ABSTRACT:
A releasable fastener for securing together lap belt straps, shoulder harness straps and a parachute ripcord lanyard. The fastener includes a buckle member or release assembly on one lap belt interengageable with a tongue member or link assembly on the other lap belt. A key on the end of the ripcord lanyard is releasably attached to the link assembly. The shoulder harness straps are engaged with the release assembly before it is coupled with the link assembly. The fastener provides for automatic release of the lap belt and shoulder harness straps to release the user from an aircraft ejection seat after its ejection from the aircraft, while retaining the parachute ripcord in attachment to the ejection seat for initiating automatic deployment of the parachute. Upon manual release of the fastener, the lap belt and shoulder harness straps are released and the ripcord lanyard key is positively ejected from the fastener to ensure its release.
