En autostol med et støtteben kan lave et tryk på over 1 ton i et uheld. da fodpropper/støttebenen ofte kun har en smal fod. placeres trykket på et meget lille område. Så vidt vides kan ingen låg på disse gulvrum holde til sådan et pres. Monteres en autostol med støttebenet på låget til et gulvrum, kan støttebenet meget let gå igennem låget, også kan autostolen ikke yde barnet optimal sikkerhed. Rent faktisk kan lågene ikke tåle mere end et tryk svarende til maks 150 kg.
Løsninger på problemet er:
1 hvis bunden af gulvrummet er bilens stålbund, er det blot at finde ud af om støttebenet kan nå helt ned til den bund. også iøvrigt fjerne låget.
2. kan støttebenet IKKE nå bunden, kan man bede pladeværkstedet hos forhandleren skære en stålplade ud. de har skabelonerne til dem liggende. derefter er det bare at lægge stålpladen ovenpå gulvrummet. man kan så vælge om man vil lægge låget på igen eller ej.
Stålpladen spreder crashforcerne ud over hele området istedet for på et meget lille område. Den stabaliserer låget så det ikke knækker.

Footwell storage compartments:
Car seats with a footprop – sometimes referred to as a floorsupport can subject the footwell to a pressure of more than 1 tonne in an accident. Due to the often small foot of the footprop, the pressure is spread over an equaly small area. This can cause the storage lid to break under the load of a car seat footprop and leave the carseat unstable and thereby reduce it´s ability to protect a child in an accident. Storage room lids can widthstand a load of about 150 kg/300 lbs.
However, there happens to be a few solutions to the storage room issue:
1. If the buttom of the compartments is the car´s own steel buttom, you can install the footprop directly on it if it can reach.
2. If the footprop cannot reach the buttom, make an appointment with the shop at the local dealership for your type of car and have them cut out a steel plate to fit the storage compartments. They should have the frames to make them. Place the steel plate on top of the compartments and the storage room lid on top of the steel plate.
A steel plate spreads the crash forces over the entire compartment area and stabalizes the lid.

Citation from Robert Bell
I usually recommend phone books. Cheap, easily modified to get the height
right.
However, it’s not a life and death issue, in my eyes. Any engineer in this
field recognizes the existence of these spaces, and the related problem of
perforated steel floor panels (the holes are there to drain the vehicle body
during corrosion proofing and painting). The bottom line is that you can use
a floor support but you better be sure that your design will do well even if
the floor fails. So most CRS designs will perform quite well even without
the floor support in use. The floor support will help diminish rotation, even if it’s placed on a plastic lid for a storage bin or on top of a perforated area in the metal itself.
Remember, the steel floor in a modern vehicle is often no more that 0.8 or
0.7 mm thick, and even if this is high performance steel, it’s still pretty
flimsy in relation to the loads that are generated in a real world crash.
