Abstract

A release mechanism employing an actuating element of a shape memory alloy material. When the actuating element is heated through its phase-change transition temperature it applies a force which moves a latch to a position which activates the higher energy stored in a drive spring for moving a retaining element out of engagement with a structure. A detent when in a captured position releasably holds the retaining element in its locked position, and the detent is moved from a captured position to a retracted position to release the retaining element when the latch is moved by the actuating element.
