Child safety seats

I am a parent of a 5yo who is beginning to enjoy RVing. We do not try to put any kind of child seat or booster in the RV. The seat belts in the living area are just not correct for use with any child restraint. The barrel chair behind the front passenger has a retracting lap belt, but it is in a strange position and won't work with anything but a no-back booster, there is no real point there. The seat belts in the couch and the dinette are the non-retracting long strap type which have to be pulled tight and again won't work with anything, except maybe a no-back booster. The point of a booster is to bring the child up to a height in which the shoulder belt will go across their body at a proper point. Since none of these seating positions have a shoulder strap, the booster is unnecessary. As pigman1 said, the point of the seat belts in the house are concerned is to keep the occupants from being projectiles in a collision or an unexpected maneuver. None of the seats or seating positions are structurally sufficient enough to provide occupant protection as you would have in a vehicle car seat. This doesn't mean it is unsafe, just that seat belts and restraints are not as useful or beneficial and the type of benefit they provide is different.
