Abstract
An aircraft passenger seat assembly, including an emergency oxygen system, a seat frame, seat bottom and seat back, and respective cushions for the seat bottom and seat back. A chemical reaction oxygen generating canister is positioned in the seat bottom below the seat bottom cushion. Oxyen flow conduit interconnect the oxygen canister and an oxygen mask compartment. A cable is operatively connected by a first end to the firing pin mechanism of the oxygen generating canister and extends from the firing pin mechanism to the mask compartment. A lever arm is positioned in the oxygen mask compartment to which a second end of the cable is attached. Another lever also includes a tether releasably connected to the lever arm and to a mask. The lever arms are mounted in the mask compartment for pivotal movement between a non-activated position and an activated position in which the cable activates the firing pin mechanism of the oxygen canister and the mask is released from a storage position into a use position for use by the passenger.
