When it comes to floor storage and child car seats, many owners of people carriers who have gone car seat shopping will have come across “this seat isn’t compatible with your car; you can’t rest the leg on the lid of the floor storage box”. It is an issue that plagues owners of vehicles with floor storage compartments, as many ISOFIX, and a few seat belt fitted restraints, have a support leg that must be used.
But why, exactly, is the support leg and the lid of the floor storage compartment not compatible?
The concern is that if a child restraint has a support leg that rests on the lid of the storage box, it could go through the lid from the force of a collision.
If the support leg did go through the box, it would compromise the stability of the seat, and it would not work how it is supposed to in a collision, potentially not protecting your child adequately.
If you have read this blog post and realised that your child’s car seat has a support leg resting on the lid of the storage box, don’t make another trip out in the car until you have confirmed if the seat is a safe fit or not.
If you have these floor boxes and you are looking for a child seat to fit your car, be aware that there may be some seats that will not be compatible with your vehicle.
If you have three full size vehicle seats with 3 x 3 point seat belts, you could fit the seat with the support leg in the middle seating position to avoid the problem, as the leg will miss both of the boxes.
Child car seats that have a support leg are classed as a “semi-universal” restraint. As the seat is a semi universal restraint it must have a vehicle fitting list. If your car is listed, you may use the seat with support leg in your car, if your vehicle is not listed; do not use the child seat. Some manufacturers will advise you to have the fitment checked by a professional, as fitment may differ between each car – even if they’re the same model!
You can find the fitting lists on the manufactures website, or it will come with the instruction booklet provided with the child seat.
Here at Good Egg, we would only recommend you fill the floor storage box with an official filler from your vehicle manufacturer, rather than use a DIY filler. Not all manufacturers have a filler available, and a DIY filler has not been tested, so it has no guarantee of doing the job you need it to.
If the leg of your seat fits down into the bottom of the box securely, it is often said to be a safe fitment. However, you do need to double check with your child seat manufacturer if they recommend this for their seat.
As with the above situation, this is often said to be safe, but to be sure contact your child seat manufacturer for their advice.
The issue about either filling the storage box or putting the leg into it is you don't know if the storgage box isa depression in the steel floor with a plastic lid or a hole in the steel floor filled with a plastic box.
In the former case can probably can be made safe, but in the latter it will probably fail no matter what is done.
