Abstract
A box (10) for safe stowage of a flight crew oxygen mask (16) having an inflatable harness (35) and a switch-on/switch-off comfort adjustment system is provided which ensures that the mask (16) is properly stowed only when the switch member (40) controlling the comfort adjustment system is shifted to the switch-off or 'emergency' position. The box (10) is preferably designed for mounting on the cockpit floor within close proximity to the intended wearer for one-handed retrieval of the mask (16) from within the box (10) and includes walls (24-32) defining an enclosure for receiving the mask (16), an apertured top cover (18) permitting a portion of the mask (16) to protrude therethrough for ready access by the wearer, and two inwardly extending abutment elements (20, 22) attached to opposing walls (24, 26) of the box. One of the abutment elements (22) is configured for receiving and supporting the body (34) of the mask (16) and the other abutment element (20) is configured for presenting an interference with the switch member (40) and thereby preventing proper mask stowage when the switch member (40) is shifted to the switch-on or the 'comfort' position, while otherwise permitting proper stowage of the mask (16) when the switch member (40) is shifted to the switch-off or 'emergency' position. Once properly stowed, the abutment elements (20, 22) will also serve to prevent shifting of the switch member (40) from the switch-off or 'emergency' position to the switch-on or 'comfort' position. The box (52) may also be designed for mounting on the cockpit wall within close proximity of the intended wearer.
