Patent attributes
An actuator for a latch assembly for securing a latched member that is linked to a trigger. The trigger may be a shape memory alloy actuating element that is actuated in response to receiving an electrical signal. The trigger may be mechanically reset to a locked state by the latched member. A method of operating the latch is also disclosed wherein the trigger is actuated in response to an electrical signal resulting in a force being applied in a first direction to a cable that connects the trigger to release the latch. The trigger is reset by exerting mechanical force on the trigger in the opposite direction. The latch system may be applied to a vehicle seat having a seat back that pivots relative to a seat base to allow the seat back to pivot over the seat base.
