Shaped memory alloy actuator
The invention is a decklid latch with a SMA actuator. The actuator includes a latch plate (14) with a ratchet (30) rotatably mounted to the latch plate (14) and is pivotal between a released position and an engaged position operable to retain a striker. A pawl (32) is rotatably mounted to the latch plate (14) and is pivotal between a an engaged position operable to retain the ratchet (30), and a release position operable to allow the ratchet (30) to pivot. An selectively-contractible wire (56) is connected to the pawl (32) by a lost motion connection (66, 68) and is operable to move the pawl (32) to the release position when contracted to actuate the latch. Portions (72) of the selectively contractible wire (56) have been annealed to reduce brittleness. Multiple material crimps (63) are used to further reduce strain on the selectively contractible wire (56). A transitional region (74), situated proximate to the annealed portion (72), provides strain relief.
