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.

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 pr…
