ABSTRACT:
A quick-loosening mechanical linking device that includes housing, a release cavity having a predetermined height, a bolt, and an actuator. The bolt is disposed within the housing and includes an attachment means projecting out from the housing, a release zone such as an intended failure zone, and a head with a piston face. Upon actuation of the actuator, the bolt deforms and/or fails at the release zone and the attachment means moves farther out from the housing by a distance equal to the height of the release cavity. The release cavity preferably includes an abutment formed at its bottom, and the actuator is preferably an electric initiator having a pyrotechnic charge.
