摘要： A mechanism for actuating a restraint divestment system for instant release of a crewman equipped with a parachute and restraint harness from an aircraft ejection seat mounted restraint assembly in the event of any emergency requiring such separation. In non-ejection emergencies, the mechanism effects the release of leg restraints, seat lap belt, and the disconnect couplings connecting the parachute riser and shoulder straps and survival kit to the harness so that, in the event of a surface emergency, the crewman can escape from the aircraft with his harness intact. The actuating mechanism includes a pull cord actuated bell crank mechanism which actuates the various release mechanisms and is then latched in its full release position, and an interlock which is actuated by the seat's ejection control, to prevent release of the parachute risers and survival kit thereafter, so that the system can then be utilized by a crewman for manual separation from the seat and parachute descent with his survival kit still attached to his harness.
