Abstract
Emergency oxygen system of the type where masks are in compartments in the backs of aircraft seats uses an underseat compartment located under the plane of the seat cushion to house the large canister of chemicals which generate the oxygen when the canister is activated. A spring loaded cable connects the two compartments so that when any of the tether cords connected to each mask is pulled, a locking pin is pulled free from a release mechanism for the cable. Once released, the cable spring immediately moves the cable axially so its lower end can actuate another release mechanism in the canister compartment to activate the canister and produce oxygen. Since the canister can reach a temperature of over 500.degree. F., its removal from the seat back reduces any possibility of burns to passengers while allowing for a lower back height and less back thickness, thereby providing more passenger living space and less obstruction to viewing of visual entertainment.
