ABSTRACT:
The invention is a smoke mask for use by passengers in an aircraft, the aircraft having a source of pressurized fresh air. The improvement comprises a container of pressurized air, incorporating a flow control valve 40 mounted to the mask 26. A first conduit 42 is coupled to the valve 40 and is adapted to deliver the flow of gas to the interior thereof upon the opening of the valve 40. The mask 26 is provided with a vent valve 76 mounted thereon which is adapted to vent exhaled air from the interior thereof. A second conduit 44 is coupled to the source of pressurized air. A disconnect valve 46 is provided for coupling the conduit 44 to the interior of the mask 26 and which is further adapted where actuated to disconnect the conduit 44 from the mask 26 and to seal off the interior of the mask. A lanyard assembly 50 is coupled to both the valve 40 and the valve 46 and is adapted to open the valve 40 and to separate the second conduit 44 from the mask when actuated. The mask 26 is configured so as to be capable of receiving and mounting an oxygen mask 200 of the type typically used on aircraft.
