Isofix vs bilsele/seatbelt

Dansk:

Er isofix mere sikkert i kollsioner ud over at være nemmere at montere rigtigt? Det spøgsmål har jeg stillet Robert Bell, som har over 35 års erfaring indenfor autostole. Hans svar kommer her:

English:

Which configuration is safer in collisions when you disregard ease of installation? I posed this question to Robert Bell who has worked in the child car restraint industry for more than 35 years. This is his reply.

Posted here with kind permission form Robert himself:

Hi Lena

The answer is both easy and a little complicated. The basic idea with ISOFIX
is to reduce the risk of misuse, and we have a few studies that make us
pretty sure that ISOFIX systems do get installed correctly more often. As a
result, they are better in crashworthiness.

But even if we disregard misuse, there are some reasons for believing that
the actual performance of the product improves. The basic goal for child
restraints is to restrain, to keep the child from moving in the vehicle,
while the vehicle structure itself crumples and absorbs energy, retarding
the movement of the passengers in a way which the automotive engineers
design to yield the best chances of reducing injury. You tie the passengers
as tightly to the car chassis as you can, and you let the chassis be the
primary means of protecting the occupants.

This is one of the ways rearward facing systems outperform forward facing
systems, entirely ignoring the issue of head and neck loads. The forward
facing system, typically anchored to seat belts, moves forward in a crash as
the seat belts extend, the plastic in the seat itself stretches, the child
stretches the internal child harness in the seat and the vehicle seat
cushion collapses under the load of the seat. The outcome is that the child
moves forward, close or beyond the 550 mm extension that is allowed in the
standard. What this means is that during perhaps a third of the crash the
child cruises, motion unchecked, forward in space, and the retardation ends
up taking place in a shorter period of time, resulting in a higher load on
the child during the 40 ms or so that remain.

This is just physics, and the rearward facing system exploits the physics of
the vehicle better.

The rearward facing seat, when placed on dash, moves very little in the
crash, perhaps as little as a centimeter or two and as a result the child is
retarded throughout the entire ride down. The loads on the child are
therefore much lower than they would be in a forward facing system. It is
also important to remember that the loads on the fragile neck and head are
reduced dramatically in relation to forward facing systems. But one of the
additional big advantages of those rearward facing systems is that they
restrain more effectively. Rearward facing seats in the rear are
disadvantaged by the rear seat back, which moves more than the dashboard,
but they are still superior to forward facing CRS in this regard.

Now you can improve both systems with ISOFIX. But the improvement is not
very dramatic for a rearward facing system, particularly one that is
installed on dash in the front seat. A forward facing system, on the other
hand, is much more tightly tied to the vehicle in the case of a European
style hard ISOFIX installation, when compared to the traditional seat belt
installed versions. It is also important to remember the contribution of the
upper tether/ floor support in reducing the motion of these ISOFIX forward
facing systems. Some of these features have also migrated to belt installed
systems, so they get a least part of the improvement.

Lastly, in studies performed by the UK Transport Research Lab, improvements
were noted in side impact performance for various types of ISOFIX seats. The
reason is most likely linked to the lateral stiffness provided by the hard
European ISOFIX anchors. These seat move less in side impact and are
therefore likely to perform better in the real world.

How is all this expressed in actual crashes? In the case of the rearward
facing systems we will be hard pressed to note improvements. Excepting fires
and the like, and accidents in which the car is crushed flat by a lorry or
cut in two by a tree, we never see fatalities in the seats now in use in
Sweden. Most every summer we have a dramatic crash in which families are
decimated in frontal accidents, except for the toddlers that are seated in
rf systems. We had one this summer in Piteå, parents killed, two siblings,
one killed and one seriously injured, rear facing toddler unharmed. So we
don’t expect major improvement in the real world of rear facing systems as
ISOFIX becomes more common.

In jurisdictions with forward facing systems, I expect that we will see a
reduction of fatalities and serious injuries among children. Most
specifically, I think we will see a reduction in compressive head and neck
injuries, as these may occur in frontal crashes when the child is flung
forward and impacts the back of the front seats with the head. ISOFIX seats
will reduce the chance of that sort of impact and the resultant injury. My
guess is that ff systems will be very much improved in the real world by the
increased use of ISOFIX equipped CRS.

Does this make sense to you? Let me know if you have questions on this
score.

Kollisionspude vs bagudvendt/Impact shield vs rearfacing

Impact shield seats vs rearfacing

 

Stolene med kollisionspude bliver næsten altid testvindere i forbrugertest udført i Tyskland hos Adac. Disse tests udgives af Tænk og FDM hvert år. De bliver markedsført som supersikre autostole.

Hvilke fordele og ulemper er der ved dem set i forhold til bagudvendte autostole?

Hvor høj er sikkerheden i autostole med kollisionspude sammenlignet med bagudvendte autostole?

 Shield seats allmost allways get the Best Buy when tested for consumers by Adac in Germany. The test results are then distributed to Which? For them to publish each year. Shield seats are market as super safe car seats.

 What are their advantages and disadvantages when compared with rearfacing systems?

How well do shield seats protect young children in car crashes compared with rearfacing systems?

Safety Performance of Shield Systems in Comparison to 5-Point-Belt Syste…

 Det drejer sig om fremadvendte autostole/this concerns forward facing car seats only

Notice

Safety Performance of Shield Systems in Comparison to 5-Point-Belt Systems
23
5 Conclusion
In the current study, accident data, test data and misuse study results were analysed to
compare the performance of shield and 5-point harness systems using Q dummies.
While the data is limited, nothing clearly suggests better performance for shield systems in
general. To the contrary, limited accident data suggest different neck injury patterns for
shield systems that cannot be evaluated with the current Q1 dummies, and higher risks for the
abdomen and thorax (but the sample size is very limited and older CRS were included in the
sample). Dummy readings in tests do not demonstrate a general benefit of shield systems for
the neck either, but the loading to the thorax and abdomen are much more severe than with 5-
point harness, which is consistent with the accident analyse results (within the limitation
regarding older CRS) and the results of other studies. This suggests that additional dummy
readings need to be considered in the evaluations. No conclusive data could be found in
misuse studies regarding the potential benefit of shields but the sample size may have been
too small to capture the limited market penetration.
In summary, based on the data that was analysed, the consequences of the current revival of
shield systems on child protection cannot be determined with certainty. No clear benefit
could be established from the observations and potential risks have been identified. It is also
unclear if test procedures are sufficient for the evaluation of shield systems real world
protection. Caution should therefore be exercised with these systems and studies should be
performed (e.g. simulation with human models, accident data analysis, comparison of
performance between older CRS for which accident data is available and newer CRS) in
order to understand and detect as early as possible potential real world issues.

Roll over crash test shield vs harness:

roll-over accident

Montering/Installation

Stol med kollisionspude:Monteringen er ligetil. Dette foregår med bilens 3-punktssele. Må ikke monteres med hoftesele.

Shield seat: The installation is very easy and quick. This is often done with the car 3 point seatbelt. No installation with 2-point belts.

Bagudvendt autostol: Montering af en selemonteret bagudvendt autostol kan godt være lidt besværlig og tidskrævende ind til man har fundet fidusen og ved hvor hvad skal være. De kan monteres i hoftesele.

Rearfacing car seat: Installing a belted rearfacing seat can be a bit troublesome and time consuming until one gets the hang of it and knows where what goes. They can be mounted with the 2-point seatbelt.

 

Hvileposition i bilen/recline position in the car

Autostol med kollisionspude: Er i kraft af sædernes hældning ikke et problem.

Shield seat: The angle of the seat cushion in the car results in a good recline position.

Bagudvendt autostol: Hældningen kan være et problem pga hældningen af sæderne i bilen. Nogle af autostolene klarer dette problem ganske godt og andre mindre godt

Rearfacing car seat: The recline position can be a problem due to the shape of the seats in the car. Some seats can handle this very well – others cannot.

 

Skift imellem biler/Moving between cars

 Autostol med kollisionspude: Er nemt i kraft af deres vægt og montering.

Shield seat: is very easy in the light of the installation and recline position.

Bagudvendt autostol: Skift mellem biler er lidt sværere hvis autostolen monteres med sikkerhedsselen. Man kan lette skiftet ved at købe et ekstra sæt forankringsseler hvorved disse kan blive i bilen.

Rearfacing seat: swapping between cars is a bit more difficult if is a belted seat. However, it is possible to make the swap easier by purchasing an extra set of teher straps and let these stay in the car.

 

Økonomi/Economics

Autostole med kollisionspude: De fleste af dem spænder over vægtklasser fra 9-36 kg og en del er billige i anskaffelse. De er ofte billige i anskaffelse. Så de er typisk meget økonmiske.

Shield seats: Most shield seats span over a wider weight range right from 9-36 kg/20-85 LBS. Most are cheap. So very money friendly.

Bagudvendt autostol: Mange af de bagudvendte autostole spænder over 2 vægtklasser. 0-18 kg eller over sidde selv til 25 kg. Klippan Triofix spænder over 9-36 kg. Så de er lidt mindre økonomiske. Men anvendningstiden er stadig lang. Enkelte er billige i anskaffelse.

Rearfacing seat: Many rearfacing seats span over 2 weight ranges. 0-40 lbs or sitting unaided – 55 lbs. Klippan Triofix is from 20-85 lbs. So they are a little less economically friendly, but usage is still long. A few are cheap.

 

Kollisionspude vs 5-Punkts-sele – even til at holde barnet i stolen/Impact shiled vs 5-point harness – the ability to keep the child in the seat.

Autostol med kollisionspude:  I og med at kollisionspuden IKKE holder barnet i stolen ved skuldrene og mellem benene er risikoen for at barnet skubbes ud af stolen i et uheld – især ved ulykker med rulning væsenligt højere end i autostole med 5-punktssele. Ligeså er risikoen for at barnet kan komme ud af stolen ved egen hjælp. Forældre der har oplevet sidstnævnte scenario, har jeg været i kontakt med via Sikkerautostol. Det ældste barn der kom ud ved egen hjælp var en dreng på 3 år.

Kollisionspuden kan ikke tilpasses det enkelte barns krop og barnet er dermed mere løst spændt fast. Dette resulterer i større rotation af barnet i disse stole.

I tillæg til sektionen “Økonomi” kan nævnes at en kollisionspude er billigere at producere end en 5-punktssele i og med at teknologien i systemet ikke er så sikkerhedsmæssigt advanceret som tilfældet er med en 5-punktssele.

Impact shield: The risk of the child being ejected from the car seat in a collision – particulary roll-over accidents and the child escaping the seat on its´ own is much higher than in seats with a 5-point harness. This is due to the lack of restraining device on the shoulders and between the legs. I have met parents with escape artists for children here at Sikkerautostol. The oldest child so far is a 3 year-old.

The impact cushion cannot be adjusted to each individual child thus resulting in greater rotation of the child in a crash, generally creating higher loads on the child.

In addition to the section on “Economics” the technology used to produce an impact cushion is not as advanced as that used with the 5-point harness. It is therefore cheaper thus reducing the prices on these seats.

5-Punktssele: Risikoen for at barnet enten kastes ud af stolen i en ulykke og at barnet kan komme ud af stolen ved egen hjælp er lille. Barnet er fastholdt over 5 stærke punkter herunder skuldrene, hofter og mellem benene.  For et korrekt fastspændt barn i en 5-punktssele er mission Ud-af-autostolen nærmest umulig. Selespændet vil desuden være meget svært at åbne for små fingre.

5-Punktssele-systemet kan nemt tilpasses det enkelte barns kropsbygning. Barnet er derfor m´´bedre fastspændt i stolen og rotationen i en ulykke dermed mindre.

I tillæg til sektionen “Økonomi” kan nævnes at teknologien som anvendes til at producere 5-punktsselen er dyrere end kollisionspuden. dette har indflydelse på prisen i butikkerne. Den del af systemet som er synligt for øjnene udgør kun en lille del af hele systemet. Inde bagved gemmer der sig en masse teknologi. 5-punktsselen placeres på nogle meget stærke punkter på stolen og placeringen af det er samtidig med til at sikre mindst mulig belastning på barnet samt den bedst mulige beskyttelse af barnet.

5-Point harness: The risk of the child being ejected from the seat in an accident as well as the child getting out of the seat on its own small. The child is held in the seat on 5-strong points of the body: The shoulders, hips and between the legs. Mission “getting-out-of- the-car seat is next to impossible. Moreover the buckle is very tough to open for small fingers

The 5-point harness can easierly be adjusted to fit and fully restrain each individual child. The child is therefore better restrained and the rotation in a crash is less than in a seat with impact cushion.

In addition to the section on “Economics”  it is worth mentioning that the technology used to produce a 5-point harness is much more advanced and more exspensive. This influences the price in shops. Also the part of the harness system that is visiable to parents is really only an small part of the entire system. There is a lot of technology hidden in this system. The 5-point harness is placed on strong points of the car seat and it´s position is carefully chosen to ensure the best overall protection of the child in a crash by better restraining it and reducing the loads on the child more effectively.

 

 Anvendelse med internt fastgørelsessystem/Using the internal restraining system

Autostol med kollisionspude: Stolene er høje og går langt op i barnehøjde. Dermed kan kollisionspuden rent faktisk anvendes til barnet vejer 18 kg. Dette rykker overgangen til selepude med høj ryg.

Shield seat: Shield seats are tall seats meaning they´ll last long in child height. Thereby the shield can be used to the full 18 kg/40 LBS before one MUST remove it. This postphones the transfer to highback booster mode.

Bagudvendt autostol:Mange af de bagudvendte autostole kan anvendes med 5-punktsselen til 25 kg. Stolene går for de meste tilsvarende op i højden. De passer typisk til barnet fylder 5-6 år. Anvendelsestid og højde på stolene passer godt sammen. Det forhindrer tidlig overgang til selepude.

Rearfacing car seat: Many rearfacing systems can be used with the harness system to 25 kg or 55 lbs. heightwise they´ll typically last until age 5 or 6. Usage and height of the seats match in these seats. This can prevent early transfer to booster seats.

 

Vægt/Weight

Autostol med kollisionspude: De vejer typisk 5-8 kg.

Shield seat: Most of them weigh between 12-1lbs

Bagudvendt autostol: vejer mellem 7-15 kg

Rearfacing seat: weigh from 15 lbs- 33 lbs.

 

Benkomfort for barnet/Comfort for child´s legs

Autostol med kollisionspude: Barnet vil typisk have masser af plads til benene. Men det kan godt være ubehageligt at skulle sidde med hængende og dinglende ben.

Shield seat: Legroom is plentyfull for the child. However, it can sometimes be uncomfortable to sit with the legs hanging and dangling.

Bagudvendt autostol: Er faktisk ret god i og med benene ikke bare hænger ned og dingler. Bøjede ben er en helt naturlig og behagelig position for børn

Rearfacing seat: is usually very good due to the fact that the legs don´t hang down and dangle. Bent legs is a natural position for children to sit in when playing.

 

Sikkerhed for ben og fødder/safety for legs and feet

Autostol med kollisionspude: Sikkerheden i autostole med kollisionspude foran er den samme som for de fremadvendte med 5-punktssele. Der er stor risiko for at benene bliver slynget hårdt og unkontrollerbart fremad og kan slås hårdt ind i feks. Forsædet med skader til følge. Skader på ben og fødder ses hyppigt I fremadvendte autostole.

Shield seat: safety for the legs and feet is the same as in forward facing systems with a 5-point harness. There is a high risk that the legs will be flung violently and uncontrollably forwards and possibly hitting car interior such as the front seat hard. The child´s legs and feet may receive injuries as a result. Leg injuries are often seen in forward facing seats.

 Bagudvendt autostol: Er ret høj. Bevægelsen i de værste kollisioner og hårde opbremsninger er meget kontrolleret og de flyver ikke fremad med stor kraft. De kan ramme ryglænet på bilsædet men med noget mindre kraft og risikoen for skader er derfor ekstremt lille

Rearfacing seat: Is very high. The movement in the worst kinds of collisions as well as in emergency braking is very well controlled and they don´t fly forward and about with great force. The legs may hit the backrest of the seating position in the car but the force is low. Therefore injuries to this part of the child are extremely rare.

 

Sikkerhed for ben og fødder I kollisioner bagfra/leg and feet safety in rearend collisions

Autostol med kollisionspude: Her er bevægelsen og kraften selvfølgelig kontrolleret og risikoen for at ramme noget I bilen er meget lav. Derfor er risikoen for skader også meget lav.

Shield seat: The movement and force is ofcause much better controlled and the risk of hitting car interior is very small. As a result the risk of receiving injuries is very low.

Bagudvendt autostole: Er ret god grundet monteringen af dem samt selve fysikken og farten I denne type kollision. De bagudvendte autostole monteres enten med en bøjle op ad ryglænet eller to ekstra seler forbindet til bunden af bilen eller forsædet som forhindrer stolene i at rejse og bevæge sig mod bagenden af bilen. Risikoen for skader på fødder og ben er derfor alligevel meget lille

Rearfacing car seat: is very good due to the installation as well as the nature and speed of this type of collision. Rearfacing systems are installed with a front brace up the back of the seating position in the car or a pair of tether straps installed in the front seat or the seat runners. Both methods prevent the seats from flipping and moving towards the back of the car. The risk of injuries to the feet and legs are still very small.

 

Beskyttelsen af overkroppen/Protection of the upperbody  

Autostol med kollisionspude/Shield seat

Maven: Der findes endnu ikke en testdukke der kan måle kraftpåvirkingen på maven. Men den er på tegnebrættet. Det er derfor vanskeligt at sige præcis hvor høj risikoen for skader på denne del er hos et barn bag en kollisionspude. Indtil da har vi kun virkelige ulykker at forholde os til, og her forekommer der skader på denne del i denne type autostol.

Vi ved at maveregionen er både blød og sårbar samt at den indeholder de livsvigtige organer.

Vi ved også, at kollisionspuden er lavet af stødabsorberende materiale.

Vi ved at det er kollisionspuden der er det primære middel der skal beskytte barnet i de alvorligste typer kollisioner. Barnet ryger ind i den og roller hen over den.

The abdomen: There is no crash teest dummy that can meassure the loads on the abdomen as of yet. However, these are on the drawing board. Therefore it is difficult to make an exact estimate of the risks with using a shield. So far we only have real life road accidents for reference, and injuries to this part of the child has happened in this type of car seat.

We know that the abdomen is both soft and fragile and that it contains the vital organs.

We are also aware of that the shield is made of shock-absorbent materials.

We know that the shield is the primary means of protecting the child in the most dangerous types of collisions. The child is pressed into the shield and rolls over it in a crash.

 

Brystkassen: her finder vi bla. Ribben og lunger. Der er risiko for skader på disse dele, og der er sket skader på disse dele i denne type stol.

The torso: here we find the ribcage and the lungs. There is a risk of injuries to these parts, and injuries to these parts have occurred in this type of child car seat.

 Nakken: Belastningerne og udmålning af skadesrisiko på nakken måles ikke ved ECE R- godkendelsen endnu. Den kan dog måles i forbrugertests samt i den svenske Plus Test. Vurderingen af målningerne i forbrugertests og i den svenske Plus Test må dog anses for at være meget forskellig. Grænsen for lav belastning ligger meget sandsynligt væsenligt højere i forbrugertestene end i den svenske Plus Test.

Det ses på vurderingen af den af autostolene med kollisionspude, som har fået et godt resultat i sikkerhed og hvor nakkebelastningen er vurderet til at være lav i forbrugertesten. Samme autostol blev i oktober 2012 udsat for Plus Test hos VTI i Sverige på foranledning af en finsk TV-kanal – Yle 5. Den faldt med et brag på trods af at testen blev udført i en noget mildere form end  normalt.

Testdukkerne har ingen sensorer i  den nedre del af nakken, hvor en belastning også finder sted for denne type autostol

The neck: The loads and the risk of injury to the neck are not meassured in the ECE R approval stage. This can only be measured in consumer tests as well as in the Swedish Plus Test.  The assessment of the neck loads seems to be very different tough. The lower assessment for neck loads in the consumer test seems to be somewhat higher than the limit set out in the Swedish Plus Test.

This is clearly visiable in the consumer test results issued to the consumers, where neck loads are deemed low for one particular shield seat that was put to test at VTI to meet the requirements of the Plus Test. The same seat failed miserably despite the fact that the Plus Test on this seat was carried out in a somewhat milder form than usual. 

The test dummies used today have no sensors in the lower neck region, where high loads can occur in this type of car seat.

Ryggen: der kan opstå høje belastninger og stræk i ryggen. dette kan dog ikke måles i tests da testdukkerne mangler sensorer i ryggen som kan måle belastningerne og skadesrisiko på denne del.

The spine: High loads can occur and back stretching can occur. This cannot be meassured as the test dummies lack sensors in the spine to meassure loads and asses the risk of injury in this area

 

Bagudvendt autostol/Rearfacing car seat

Maven: Barnet presses ind i stoleryggen og i retning væk fra 5-punktsselen.

5-punktsselen spreder kollisonsbelastningerne over 5 stærke punkter på barnet: Skuldre, bækken og hofter.

5-punktsselen er desuden designet således at selve materialet den er lavet af udvider/strækker sig med op til ca 10% – primært i en fremadvendt autostol. Strækket vil være mindre i en bagudvendt autostol, i og med at belastningen på selen er mindre

Risikoen for skader på den del af kroppen er derfor ekstremt lille.

The abdomen: The child is pressed against the back of the child seat and away from the 5-point harness.

The forces are spread over 5 strong spots on the child: Shoulders, pelvis and hips.

The 5-Point harness is made of strong stretchable materials that make it possible for it to stretch  app.: 10% in a crash if the child is placed in a forward facing seat. The stretch is less in a rearfacing seat as the loads on the  harness are less severe.

The risk of injuries to this area is extremely small.

Brystkassen: samme som maven.

The torso:  Same as the abdomen.

Nakken: Samme som ovenfor.

The neck: Same as above

Ryggen: samme som ovenfor

The spine: Same as above

They are way above the maximum level in the Plus Test.

 

Udsyn ud af bilen / View out of the car

Autostol med kollisionspude: Udsynet er begrænset i kraft af stolens placering samt dens sidevinger. Barnet kan se ud af sidevinduerne hvis det læner sig fremad og ud af stolen beskyttende sider. Ellers er der udsyn til forsædernes ryglæn og en smule af den ene forældre. Dette har denne type autostol tilfælles med alle andre fremadvendte systemer.

Shield seat: The view is reduced due to the direction of the seat in the car as well as it´s deep sidewings. The child can see out the sidewindows if it leans forward and out of the protective sides of the seat. Other than that, it will be able to see the back of the front seat and a bit of one of the parents. This is common for all types of forward facing systems and not restricted to this type.

Bagudvendt autostol: udsynet ud af bilen er altid godt igennem sidevinduer. Mange af dem placerer barnet højt nok til at de kan se ud af bagruden. Udsyn med det samme. Med andre lader dette vente lidt på sig.

Rearfacing seat: View out of the car´s sidewindows is allways good from the start. Some seats place the child high enough for them to see out the backscreen very early on. Others place the child lower and rearview will come later.

Kommunikation med ældre søskende/Communication with older siblings

Autostol med kollisionspude: Se afsnittet om udsyn hvis de andre børn er fremadvendte. Kommunikationen er derfor ikke helt uden risici.

Shield seat: See the section about the View out of the car. If the other children are forward facing too. Communicating with sibs is therefore not without risks.

Bagudendt autostol: Er nem, i og med børnene sidder modsat hinanden i bilen. Dette forhindrer begge børn i at læne sig fremad og ud af stolenes beskyttende sider – noget som have have negativ indflydelse i en evt kollision.

Rearfacing seat: is easy as the children sit opposite one another in the car. They don´t have to lean forward and lout of the seats´ protective sidewings in order to see one-another and talk – something which can impede the safety in a car crash.

 

Pladsbehov I bilen/Space requirements

Autostol med kollisionspude: En hvilken som helst type fremadvendt autostol har 2 pladsbehov.

Det ene ses så snart autostolen sættes ind i bilen.

Det andet ses kun i de alvorligste typer ulykker.

Fremadvendte autostole inkl disse er designet til at barnet slynges fremad med op til 55 cm fra panden. Er stolen fejlmonteret eller fejlanvendt øges dette. Dette er naturligvis forbundet med risici.

Shield seat: Any type of forward facing child car seat has 2 types of space requirements in the car.

One is what you see when you have installed the seat into your car.

The other one can only be seen in the most serious types of accidents.

 Forward facing seats incl. these are designed to let the child go forwards by up to 55 cm from the child´s forehead  IF used correctly. The number will rise if the child seat is incorrectly mounted or incorrectly used. This is ofcause not risk free.

Bagudvendt autostol: En bagudvendt autostole har en type pladsbehov og det er den man ser når stolen monteres I bilen. Stolens ryg opfanger barnet i kollisionen. Pladsbehovet for selve stolen kan være stort men kan kun vurderes af ejeren selv. Til gengæld leverer de ikke overraskelser i en kollision.

Rearfacing seat: A rearfacing seat has only one type of space requirement: The one that you see when the seat gets installed into your car. Physical space requirements vary a lot and can only be judged by the owner. In turn, they do not give you negative surprices in crashes.

 

Sidevejs stabilitet/Sideways stability

Autostol med kollisionspude: God sidevejs stabilitet kan kun opnås med en isofixmodel.

Shield seat: A good sideways stability can only be achived with isofix.

Bagudvendt autostol: God sidevejs stabilitet er nemt at opnå med alle store  bagudvendte stole. De kan nemt monteres stenhårdt i bilen.

Rearfacing seat: A good lateral stability is easierly achived with all big rearfacing seats.

 

Sætte barnet ind I stolen/Boarding the child

Autostol med kollisionspude: At sætte et barn in di en autostol med kollisionspude er altid meget nemt. De lærer hurtigt at kravle ind og ud selv.

Problemer kan dog opstå på parkeringspladser fordi bildøren skal åbnes helt op. Dette er ikke specifik rettet mod denne type fremadvemdt autostol. Sådan er det for dem alle.

Shield seat: Putting a child into a shield seat is allways very easy. They soon learn to climb in on their own.

 There might be problems in parking lots because the car door must be fully opend. This is the same for all types of forward facing systems.

Bagudvendt autostol: Små børn behøver ofte hjælp. Det er lidt sværere at bestige en bagudvendt autostol end en fremadvendt. Alternativt kan man sætte dem på kanten af stolen sidevejs og svinge deres ben rundt. De vil med tiden kunne stige ind i dem på egen hånd.

Rearfacing seat: Small children will often need help as it is more difficult to mount a rearfacing seat than a forward facing seat. Alternatively you can put the child into it sideways by placing the child on the side of the seat and swing the legs around.

 

3 Autostole I bilen/Getting three car seats across

 Autostol med kollisionspude: Det er ikke muligt at få 3 fremadvendte autostole ind I en bil med mindre der er tre lige brede bagsæder.

Shield seat: It is not possible to get three forward facing seats across unless the car has three full-sized backseats.

 Bagudvendt: Det er muligt at få tre autostole på tværs I bilen selvom der kun er ½ sæde I midten.

  Rearfacing seat: It is possible to get three seats across even if there is only ½ a seat in the middle.

 

Tilpasning af kollisionspude vs sele til barnet/

Adjusting the shield vs the harness system on the child

 

Autostol med kollisionspude: Det er en myte at barnets størrelse ikke har nogen betydning for anvendelsen af en autostol med kollisionspude. Der er ingen sandhed i den. Mange forældre skifter fra babystol til autostol med kollisionspude så snart barnet vejer 9 kg. Men at barnet vejer 9 kg er langt fra nok. Ej heller at de er 9 måneder gamle og kan sidde selv.

 

Hvis barnet er for lille, kan det nemt komme ud af stolen ved at mase sig enten under kollisionspuden eller kravle over den. Dette er sket desværre. 

Puden må ikke sidde så højt på barnet at armene hæves over skulderniveau. Desuden skal man se hvor meget plads der er under puden, for at forhindre barnet i at kravle eller glide under puden.

Ydermere er det vigtigt IKKE at efterlade såkaldt ”slack” i sikkerhedsselen. Den skal strammes – dog ikke så meget at det bliver ubehageligt. Er sikkerhedsselen for løs har barnet en større chance for at komme ud af stolen ved at skubbe kollisionspuden fra sig. Det svarer til at 5-punktssleen ikke strammes ordenligt.

Shield seat: That the height of the child does not matter when placing it in a shield seat is an untrue myth. Many parents make the transfer as soon as the child hits 20 lbs or 9 kg. That does NOT mean it is okay to make the transfer from babyseat to a shield seat at this stage – not even when they can sit unaided and are 9 months old

The child can easierly come out of the seat by climbing over the shield og squeeze or slide under it. This has happened unfortunately.

The shield must not raise the child´s arms above shulder level. It is also important that the gap between the legs and the shield is not big.

It is also important to make sure there is no slack in the seatbelt. It is easy for the child to push the shield away and climb out of the seat or slide under the shield. A loose seatbelt is like a loose 5-point harness

Bagudvendt autostol: Vi ved at 5-punktsselens primære function I en bagudvendt autostol er at sikre barnet er i stolen når der sker et uheld.

Vi ved at det er autostolen selv som er det primære middel der skal beskytte barnet.

Derfor vil man opleve forskellige anbefalinger ang. Selejusteringen på barnet.

Nogle producenter har valgt en retningslinje for alle deres stole for ikke at forvirre.

Andre producenter skelner mellem de bagudvendte autostole som kan vende begge veje og dem som kun kan anvendes bagudvendt . I de autostole der kan vende begge veje vil man se at selestropperne skal være placeret lige på elelr lige over barnets skuldre. I de bagudvendte autostole som kun kan bruges bagudvendt vil man derimod kunne læse at selestropperne må være lige på skuldrene eller lige under fra man sætter det lille barn i til det store barn er vokset ud af stolen. Britax er et godt eksempel på dette.

Med andre ord FØLG PRODUCENTENS ANVISNINGER.

Rearfacing seat: Vi know that the primary function of a 5-point harness is to make sure the child is in the car seat when a crash happens.

 We know that the car seat itself is the primary menas of protecting the child in  a crash.

Therefore, the recommendations regarding harness position will differ.

Some manufactorers advice you to position the shoulder straps at or  slightly above the shoulder in all of their seat in order not to casue confusion.

Other manufactorers will advice you to position the shoulder straps at or slightly above in seats that can be used both rearfacing and forward facing. In seats that can only be used rearfacing they´ll advise you to position the harness slightly at or below the shoulders. This goes right from the baby is placed in the seat for the first time until the big child has outgrown the seat. Britax is a good exsmaple of this.

In other words: FOLLOW THE INSTRUCTIONS BY THE MANUFACTORER.

Dansk Haverikommission

 

Så er det endelig blevet helt officielt: Bagudvendt placering af børn under mindst 4 år i bilen er den mest sikre løsning. Dette har Dansk Haverikommission slået  fast via undersøgelser af rigtige ulykker på de danske veje.

Resultatet er blevet offentliggjordt i November 2012.

Læs Haverikommissionens endelige rapport her.

 

 Sikkerhedsudstyr Til Børn I Biler

 

At bagudvendt er bedst hersker der ingen tvivl om. Bare se på videoen her og læg godt mærke til testdukkens hoved i den fremadvendt stol.

There is no doubt what is best for children in cars: facing the back of the car. Just watch the video and pay close attention to the forward facing test dummy´s head

I-Size – Nyt Reglement/New Regulations

New Regulation Reqirement for Child Restraint Systems

Unece.org

UNECE adopts three new regulations to increase the safety of drivers and passengers

Published:14 November 2012

 

 

Notice

 Child Restraint Systems (CRS)

The main aim of the new child restraint system is to create a well-anchored seat like that of an adult, safeguarding children to the maximum degree possible in the event of a collision or of abrupt deceleration of the vehicle, by limiting the mobility of the child’s body.

The new Regulation on CRS foresees four new sets of provisions;

  • § The introduction of a simplified classification, called “ i -Size” which is based on the stature rather than the weight of the child, which was found to be more appropriate to ensure the best protection.
  • § The introduction of a side impact test procedure which will lead to a better protection of the child’s head especially for younger children. Until today, there was no dynamic test requirement for lateral impacts.
  • § The mandatory rear-facing position of children is extended to 15 months, instead of 9 months in the current Regulation.
  • § The introduction of a “support leg” which connects the child seat with the vehicle in order to create a tight and secure position of the seat during any driving condition.

Childsafety Europe

Notice

ANEC, ECSA and Euro NCAP share the view that rearward-facing travel is the preferable
way to transport children and should be encouraged for as long as possible. We especially
note the recommendation of the European Parliament “that children up to the age of three
travelling in vehicles should be secured in rear-facing child seats”iv
.
Consequently, the adoption of a new regulation on child-restraint systems (the “I-size
Regulationv
”) by UNECE (United Nations Economic Commission for Europe) World Forum
for the Harmonization of Vehicle Regulations (WP 29) at its 158th session on 14 November
2012 has been welcomed warmly by ANECvi, ECSA and Euro NCAP as progress in the right
direction. The new “I-size regulation” requires – apart from other improvements – the
mandatory rearward-facing transport of children until the age of 15 months

1. No mass groups./Ingen grupering baseret på vægt.

2. Classification based on standing height./Grupering baseret på stående højde.

3. Maximum permissible weight (Child+CRS) 33kg./Maks. vægtangivelse (Barn + autostol) = 33 kg for isofix

4. Age limit for forward facing use.Min. 15 month./aldersbegrænsning for fremadvendt placering: Mindst 15 måneder

5. Use of measurement device for CRS size control./anvendelse af udstyr til udmålning af autostolens dimensioner.

Klippan Triofix.

6. The use of Q-dummies for frontal, rear and lateral impact on a new test bench./Anvendelse af Q-Test dukker i frontal, bagende og sidekollisionstest på en ny testbænk.

7. The use of a support leg as well as a top tether as universal anti rotation device./Brugen af støtteben eller Topsele som universiel anti-rotationsmiddel

 

 

1. Grupering af autostol baseret på vægt fjernes idet mange forældre sætter deres børn i en større autostol for tidligt.

1. Grouping the car seats according to mass will be terminated as many parents have transferred their children to bigger seats too soon.

3. Indførelsen af en maksimal vægt for isofix stole op til ca 4 år skal forstås som at isofix er tested til en samlet vægt på 33 kg = autostol + barn. Fremadrettet bliver det således at hvis en autostol + base vejer 8 kg ialt i og med den skal testes med en 23 kg tung testdukke for at kunne blive godkendt til 25 kg 25+8= 33. Så må barnet sidde i den med 5 punktsselen i til det vejer 25 kg. Vejer stol og base 8 kg ialt, må barnets veje 25 kg. På det tidspunkt vil de fleste børn være 5-6 år gamle.

Vejer stolen mere end 8 kg testes den med den 14½ kg tunge testdukke Q3 istedet for

The introduction of a maximum weight car seats up to app 4 years of age means that the isofix system has been tested to a maximum weight of 33 kg which means the total weight of car seat + base unit + child. This means that if the car seat + base (if there is a base unit) is 8 kg, it can be crashtested with the Q6 dummy that weighs 23 kg and thereby the seat can be approved for 25 kg children. Most children will be 5 or 6 years old by then.

If the isofixseat weighs more than 8 kg it will be tested with the Q3 test dummy weighing 14½ kg.

4. Vægtklassifikationen erstattes med alder, fordi vægtangivelserne har vist sig at lede til fejlanvendelse i form af for tidlig overgang til en større stol.

Weight classification will be replaced by age as the weight clas. has proven to be too confusing to parents thus resulting in misuse a.o. early graduation from one size of seat to the next.

5. Man anvender et specielt værktøj til at måle på stolenes bredde, dybde og højde for at sikre de kan være i biler som har I-Size isofix systemet. Man vil derigennem sikre at autostolene kan være i bilerne samt monteres sikkert i dem uden at tjekke billister. 

Mht. ældre biler med et ældre isofix system (2-punkts system) vil man fortsat kunne bruge I-Size såfremt stolene passer ind i disse biler.

A special tool is used to meassure the width, depht and height of the seats. this is to make sure that they will fit into cars that are I-Size ready – meaning they are equipted with the new Isofix 3 point system without cheking wether or not the seats will fit.

Regarding cars with the old isofix system. It is possible to use an I-Size car seta provided that the car has all the equiptment for it – such as the third anchorage point.

Anvendelse af stole godkendt ECE R 44/04 

Autostole godkendt efter disse regelsæt, vil kunne bruges efter ikrafttrædelsen af det nye regelsæt. Men sandsynligvis kun i få år efter. det er ikke sådan at hele det nye reglement træder i kraft på én gang. Det bliver indført i 3 stadier. Det betyder heller ikke at autostole som er godkendt ihenhold til ECE R 44/04 ikke ville kunne godkendes i det nye regelsæt. Det kræver blot at firmaerne lader dem teste igen. Med tiden vil autostolene alle have isofix. det kræver at alle biler fremover udstyres med isofix, hvilket bliver et krav til bilproducenterne. Så det er ikke sådan at man skal smide sin autostol ud hvis den ikke har isofix. ved indtrædelsen af det nye reglement.

Første stadie indføres per 9.Juli 2013 efter planen. Første Stadie kommer til at indbefatte.

 - bagudvendt placering af børn under 15 måneder.

 

Hele det nye reglement ECE R 129 skulle være fuldt implementeret i år 2018. Autostole lavet efter ECE 44/04 reglementet vil kunne bruges i få år derefter.

 

 

Usage of seats approved for ECE R 44/04:

Car seats approved according to this set of regulations can be used even after the introduction of the new regulations. But this will likely be so for a few years after the introduction. All the changes that will be in the new regulations won´t be introduced all at once. it will happen over a number of a few years and in 3 stages. Furthermore, it does not mean that seats approved to meet the ECE R 44/04 regulations cannot be approved to meet the new regulations. It is up to the manufactorers to let them be tested again. The plan is that all seats will have isofix, and so this calls for the car manufactorers to add the isofix system to all their cars. In other words, do not throw your non-isofix car seat away as soon as the introduction of the new regulations begins.

 

The introduction of stage 1 will happen end of 2013-begining 2014 according to plan. This stage will include mandatory rearfacing to minimum 15 months. Parents are strongly advised to buy the new seats instead the old ones.

 

All three stages of the new regulations named ECE R 129 should be completed by 2018. Parents can continue to use seats that meet the ECE R 44/04 a few years after that

Fra babystol til barnestol/From baby seat to child seat

Hvornår kan man skifte fra babystol til 13 kg over til barnestolen til 18 kg? Svaret kan drille selv personalet i babyudstyrsforretninger. 

 

Svaret kommer an på hvilken stol man vælger i den næste gruppe. 

Fremadvendt autostol:

* Barnet skal veje mindst 9 kg. 

* Barnet skal kunne sidde stabilt selv

* Barnet bør være fyldt 9 måneder

De to første kriterier skal være opfyldt som det ser ud nu. Det sidste skal ikke, men bør være opfyldt.

 

Bagudvendt autostol:

Her er kriterierne for skiftet noget mindre betydelige end ved skift til en fremadvendt autostol. Faktisk er det sådan at der ikke er noget der skal være opfyldt. Nogle kriterier bør være opfyldt. Hvad disse er afhænger helt og holdent af autostolstolen og det kan læses i brugermanualen.

Nogle af stolene går helt fra fødslen.

Nogle går fra 0 kg. men bør først anvendes når barnet kan sidde stabilt selv.

Nogle går fra 9 kg og bør sidde stabilt selv

Rollover Crash – Finland 2012

Rollover i glatføre i Finland med 60-70 km/t. 1Årig dreng slap helt uskadt.

Rollover accident in Finland at 60-70 km/h. 1-year-old boy unharmed.

My husband yesterday skidded with our car at a speed of 60-70 km/h (38-45 mph), spun around and hit the front wheels in the snow which led to the car flying through the air landing on drivers side at a ditch on the side of the road.

Our one year old son made it without a scratch, he even sat there laughing when my husband looked at him after the accident.  He was then “hanging” in his seat.  Good seat and a guardian angle for our son:-)

Klarade sig mirakulöst Trots att bilen krossades i krocken klarade sig den ettåriga flickan utan allvarliga skador.
Foto: ANDERS WESTERGREN

Ettåringen lever – tack vare bilstolen

Hennes mamma, pappa och lillasyster dog när familjens bil krockade med en buss.

Men den ettåriga flickan i framsätet klarade sig utan allvarliga skador – tack vare bilbarnstolen.

Familjens silvergrå Volvo 945 totalförstördes i krocken. Den tillåtna hastigheten på vägsträckan är 90 kilometer i timmen och bilen voltade efter den våldsamma kollisionen.

Polisen var först på plats och kunde direkt ta ut den ettåriga flickan som satt i en bakåtvänd bilbarnstol i framsätet. De andra fyra i familjen satt fastklämda. Ettåringen vårdades i går på Sunderby sjukhus i Luleå, men hennes tillstånd är stabilt.

Utan skador
Flera experter som Aftonbladet talat med är överens om att bilbarnstolen räddade hennes liv. Tack vare skyddet från stolen och att hon satt så lågt fick hon inga allvarliga skador trots att bilen krossades.

– Den räddade definitivt hennes liv. Särskilt med tanke på att det var en frontalkrock, säger Jan Wenäll, forskningsingenjör på VTI, Statens väg- och transportforskningsinstitut.

”Bästa skyddet”
Han undersökte samtliga trafikolyckor där barn dödats 1992-1997. Av 79 döda barn upp till 15 år satt bara nio i bakåtvänd bilbarnstol, åtta av dem färdades i bilar som totalförstördes i en krock med tåg, buss eller lastbil.

– Barn som sitter i bakåtvänd bilbarnstol har det allra bästa skyddet i en personbil, säger Jan Ifver, statistiker på Transportstyrelsen.

Fejlanvendt stol/Misused seat

Isofix løser problemer med monteringen langt hen ad vejen. men det løser desværre ikke det store problem med Misuse – altså fejlanvendelse. I katagorien fejlanvendelse ligger bla.

Forkert selehøjde

Tykt overtøj

Selen i stolen snos ved ændring af selehøjde

Selen sættes fast i to forskellige hak

Selen er for løs

Tidligt skift til næste stole-størrelse

isofix solves issues with the installation to a huge degree. However, it does not solve problems regarding various types of “Misuse”. Misuse is a huge problem, but parents are not aware of the mistakes they make – if they make them. Misuse includes

Incorrect harness height.

Thick clothing means wrong harness positioning on the shoulders

Twisted harness straps

The harness straps are in two different slots

The harness is too loose

early graduation to a bigger seat

Her er selen for lav/The harness is set too low

her er selehøjden korrekt/Harness height is correct

her er selen for løs/The harness is too loose in this picture

Endnu et billed af selen mens den er for lav/Another picture of the harness set too low

Tykt overtøj resulterer her i en fejlposition af selen på skuldrene og den kan ikke spændes godt nok/The thick jacket has resulted in wrong positioning of the harness on the shoulders and cannot be tightend enough.

Korrekt seleposition på skuldrene og selen er spændt godt nok/Correct harness positioning on the shoulders and it is tight enough

Endnu et eksempel på korrekt højde og position af selen som er strammet korrekt. Another exsample of correct harness height and positioning as well as correct tightening.

 

 

Denne ulykke skete i Storbritanien i slutningen af november 2011. Hvilken stol drengen sad i vides ikke. Men faktum er at han IKKE var korrekt spændt fast i sin autostol. Foruden at han ikke var korrekt spændt fast i stolen, er sandsynligheden for at selve stolen ikke var korrekt monteret osse høj. Ulykken understreger vigtigheden af at læse manualerne der følger med autostole samt at lytte til eksperters råd

Autostole laves med børns sikkerhed i bilen for øje. Anvisninger bør følges til punkt og prikke.

This accident happend in Great Britain in ultimo November 2011 The type of seat that the boy used is unknown. But fact is that he was not correctly fastend in the seat. The likelyhood that the seat itself wasn´t correctly installed is high. The accident really stresses the importance of reading and following the user guide that comes with your car seat as well as not to ignore expert advice.

Car seat anufactorers make car seats with childrens´ safety in cars as their 1st priority.

MERCY FOR MUM WHO KILLED HER BADLY-STRAPPED TODDLER IN CRASH

 

 

 

 

 

Sophie Boyeldieu couldn’t explain to police why she had been out of control at the wheel.

 

Friday November 25,2011

 

By Paul Jeeves

 

A WOMAN motorist who smashed head-on into a minibus caused the death of her baby son because she hadn’t strapped him in properly.

 

Sophie Boyeldieu, 21, was seen repeatedly swerving at 60mph across a carriageway into the opposite lane before the horrific crash.

 

The mother broke down in tears when told 17-month-old Aidan might have survived had she fitted his seat straps correctly in the Honda Jazz.

 

But he was loose enough to smash his head on the roof when the car flipped over, and died despite being airlifted to hospital.

 

Boyeldieu and her partner John Grice were on the A63 near Selby, North Yorkshire, in April when she began to drive erratically.

 

She hit a charity minibus and the volunteer driver, ­Desmond O’Neills, suffered multiple injuries including a broken collar bone.”

Kayne West og Kim Kadarshian har købt en Cybex Sirona til deres baby.

Kim Kadarshian´s Cybex Sirona

 Crash test

 

Cybex opgraderer Sirona: Cybex er muligvis igang med at lave Sirona lidt større på baggrund af kritik på dens størrelse fra brugere.

Cybex to update the Sirona: Rumor has it that Cybex are about to make the back of the Sirona longer due to criticism from parents on it´s rather short back.

 

Hvorfor har Sikkerautostol.dk ikke denne stol/Why does Sikkerautostol.dk not have this seat for testfitting?

Lad mig slå en ting fast med 7-tommersøm: Det er ikke pga manglende sikkerhed og dårlig kvalitet. Cybex Sirona er en MEGET sikker og kvalitetsmæssig rigtig god autostol. Men den er meget kort i ryggen, og vil derfor næppe holde til 18 kg eller ca. 4 år.

Let me put one thing straight right away. The reason that sikkerautostol.dk doesn´t have the Cybex Sirona is NOT due to poor safety and quality. The Cybex Sirona is a VERY safe and good quality car seat. However, it is very short, and will likely not last until 18 kg or app 4 years of age.

 

Stolen sælges i Danmark hos
