ABSTRACT:
A latch for use on an aircraft ejection seat and the like to permit the optional selection, prior to ejection, as to retention of a survival kit. The latch includes a housing for receiving a bolt which is retained in position by a detent spring, and a two-position toggle having a lever extending therefrom and maintained in position by a toggle detent. In one position, the toggle retains the bolt fixed in the housing and a lanyard passing through a hole in the bolt has one end attached to the survival kit and the other end to the ejection seat through a cord cutter. In this position the cutter is activated and the survival kit separates from the seat structure. With the toggle in the other position, the bolt slips out of the detent spring upon ejection and the lanyard with the bolt attached secures the survival kit to the ejection seat.
