摘要： A vehicle-seat component releasing device including a shape-memory actuator is provided to simply and efficiently operate the vehicle-seat tippable components, such as a headrest and a backrest, by controlling movement of the seat components sloping down from an upright position or reversely from the downward slope to the upright position through the shape-memory actuator serving as a bistable actuator. A vehicle-seat component releasing device comprises a first member; a second member installed on the first member to shift between a first position and a second position against the first member; a locking unit(6) for locking the second member at the first position; and a lock releasing means including a shape-memory actuator(7) composed of a shape-memory metallic element. The shape-memory actuator comprises a means for providing electric current through a shape-memory cable having variation in length and generating a heat and a sheath(18) for surrounding the shape-memory cable. The sheath is parallel to the shape-memory cable and mechanically set between a controlling member and a controlled member so that the controlled member is electrically driven by activating the shape-memory cable or mechanically operated by using the sheath as a tie-rod.
