ABSTRACT:
A rear-facing crashworthy set for fixed wing aircraft comprises a seat facing in the opposite direction to the direction of flight of the aircraft and energy absorbers attached between the seat and the floor of the aircraft. The energy absorbers include forward energy absorbers attached to a forward section of the seat, intermediate energy absorbers attached rearwardly of the forward energy absorbers, and rearward energy absorbers attached rearwardly of the intermediate energy absorbers, all energy absorbers having the capability of operating in both tension and compression. Stabilizing members are attached between the seat and the floor of the aircraft. Energy attendant upon a crash is absorbed, and the seat is enabled to flex with crash-induced distortions of the floor to prevent separation of the seat therefrom, thus preventing severe injury or death as a result of a second impact of the detached seat with a structural member of the aircraft, such as a bulkhead, under crash conditions.
