Car seat without bus seats?

Hey guys...

So... now trying to work out where my son's seat will be mounted/restrained. The front passenger seat (not installed yet) I've been told is the only safe spot.. however I don't like the idea of him being up front. I like the idea of more steel and space around him.

What are you guys doing for child seat mounting when not using a factory seat in the rear passenger area of your bus? My shorty doesn't have the space for it.

I was thinking about a forward facing seat that could be mounted in the aisle way and be removable... with mounts and restraints anchored to the frame... or a harness bar under the couch ( again anchored to the frame.. not wood) but have been told by countless people that mounting the seat sideways is a BIG no-no. Not sure how force applied to the seat would be any different mounted that way then mounted facing forward and being hit from the side.. but anyways...

Thanks for the input.

Sideways isn't good for the child in an impact.

So I've been told... but no one can tell me how it is any different then a forward facing seat during a side impact collision such as someone running a stop light or sign.

So what are others doing?

I'd say side impact would be less severe to a heavy bus. Severe impact is more likely from a sudden stop. Rear facing is obviously best for the very little ones. Side facing child seats are illegal in my country.

So how to implement a forward facing seat when there isn't room for something permanent.

Some people retain a couple of seats to install a booth-style dinette. The rear-facing seat would be a good place for kids to travel.

Side impacts usually happen at a 35mph impact force or less, where head on collisions frequently happen at 100mph force or greater.

I guess so... unless a large truck blows a light or something along those lines.

Well I think I've got a plan in mind. I have a small seat that folds down nice and compact. Its fairly narrow as well (going to test fit his car seat on it tonight to see how well it fits).

Now my thought is basically a sandwich plate setup... Cut a piece of 1/8-1/4" plate say 12x12 or so. Drill 4-6 holes in the plate and either thread the holes or weld/capture some 3/8" nuts to it. Mount the plate under the bus body floor and mark/drill the holes up all the way through the floor. Permanently attach the plate via 4 more holes and bolts. Then a couple long bolts with handles on them that will go through the seat mount.. through the floor.. threading into the large plate under the bus body. Would only take a few minutes time to attach and remove the seat from the center aisle... would fold up and fit under the bed for storage once we reach our destination. Should also be narrow enough to squeak by while in place if we weren't stopping for long. The seat has built in restraints so it should work fairly well. I'll beef them up if they aren't up to the task.

I am also tossing around the idea of doing the same thing.. but using L-Track or "Aircraft Track" instead of the large plate. Either way, I think it would be plenty strong to keep him in place... yet be easy enough to remove and stow away.

Thoughts?

Having the seat mounted sideways would make a front/rear collision more like a side impact collision. Most car seats in the US are not tested for or rated for protection in side impact collisions. And even when they are they are typically not as good in side collisions as they are in a frontal or rear crash. Front crashes are the most common type of collision, but side impacts are much more likely to result in fatalities including of children in car seats.

In a front collision the child is restrained by the straps, which distribute the force and prevent excess forward movement. This distributed force and lack of head restraint can still injure / kill very small children which is why they go in rear facing seats. Then the force is distributed more evenly across their entire body by the seat shell and the head is supported. The reclined body angle also helps reduce head movement in a rear collisions. In a side collision the straps are often less effective at preventing movement. And the child is thrown sideways until the less restrained parts of their bodies, often the head, slam into the side of the carseat.

The more improvised your seat and attachment method are, the less confident you can be about the results in a crash. Even if the seat used to mount the car seat into is a tested automotive type seat, if it's not mounted more or less exactly as originally intended all bets may be off with regard to the testing done to ensure safety of the seat design. The whole seat, mount, and attachment to the vehicle works as a system in the event of a crash. In the worst case the whole thing could shear loose and be launched with the car seat still attached.

IMHO this is a place to be very conservative with the creativity. We are going with original bus seats with integrated child restraints that will be mounted essentially as originally intended. If you can't do that I'd say the original front passenger seat is the next best thing. If it has one, the front passenger air bag should probably be disabled.
