ABSTRACT:
Life and weight saving aircraft seat structure employs frame supported interconnected pneumatic seat and seatback cushions with automatic compensation for pressure and temperature changes primarily by provision of predetermined pneumatic overflow envelope elastic force variables; in preferred embodiment self-extinguishing inflating gas is provided, a vented sleeve or sheath limits amount of expansion of the overflow envelope and an overflow relief valve limits system pressure.
