ABSTRACT:
An energy absorbing seat arrangement, particularly for a helicopter, in which a seat pan is carried by a frame slidably mounted on parallel upwardly extending pillars secured to the helicopter. In normal conditions, downward sliding of the frame on the pillars is prevented, in one embodiment, by metal rods fixed with respect to the pillars, and extending through drawing dies fixed with respect to the seat frame. In a variant the rods and dies are replaced by a deformable metal tube and a mandrel extending through the tube. In the event of a crash in which rapid downward movement of the helicopter and the pillars is halted suddenly, the seat and seat frame continue to move downwardly, sliding along the pillars, while drawing of the rods through the dies, or drawing of the mandrel through the deformable tube, to dissipate the kinetic energy of the seat and its occupant relatively gradually.
