ABSTRACT:
In a safety seat installation in a vehicle such as a bus or coach, where the seat is one of a longitudinal row of similar forward facing seats, the back is constructed in two portions 4 and 5 which are pivotally mounted at 3 and 6 respectively. In the event of sudden deceleration, for example in an accident, the rearwardly seated occupant's knees push the bottom of the lower seat back portion 4 forwards so that the top of this portion pushes the upper seat back portion 5 backwards into a position to restrain the rearwardly seated occupant's torso.
