ABSTRACT:
A crashworthy seat comprises a sitting platform and a back. The sitting platform is supported by a frame adapted to be secured to the aircraft. The frame has upright members supporting the back of the sitting platform for vertical sliding movement under controlled resistance provided by an energy absorbing mechanism which comprises an elongate member extending along each upright and a cooperating cutting or deforming tool carried by the seat back. In a crash situation, the sitting platform slides downwardly under controlled resistance provided by the cutting tool cutting a shaving from the elongate member or by the deforming tool deforming the elongate member.
