ABSTRACT:
A crashworthy vehicle seat comprises a seat bucket member suspended by supporting webs engaged with rotary energy absorbers attached to the overhead of the vehicle. Beneath the seat bucket member, pairs of extensible and compressible energy absorbers are attached between the seat bucket member and the floor of the vehicle. Upon impact, the rotary energy absorbers and the extensible and compressible energy absorbers are arrayed to permit controlled and energy absorbing movement to reduce the probability of injury to the occupant of the seat. In the one form of the seat it accommodates itself to fore and aft forces acting upon it. In a modified form of the seat the design is optimized to accommodate these forces. In further forms of the seat the design is arranged for a sideward or lateral facing seat and the design is optimized to accommodate lateral forces.
