摘要： A restraint divestment system for releasing a crewman equipped with a parachute and restraint harness from an aircraft ejection seat mounted restraint assembly in the event of a ground emergency. A single point crewman actuated mechanism releases the 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 ground emergency, the crewman can escape from the aircraft with his harness. The actuating mechanism includes an interlock which prevents release of the parachute risers and survival kit in the event of an emergency ejection from the aircraft when in-flight, so that the system can then be utilized by a crewman for manual seat separation and parachute descent. The actuating mechanism includes a pull cord actuated bell crank mechanism which actuates the various release mechanisms and is latched in its full release position. The parachute riser disconnect couplings and the survival kit disconnect couplings are actuated by rapid deflagrating cord, and the cord system includes quick release pull away swivel fittings allowing the rapid deflagrating cords to be separated quickly from the ejection seat.
