A contractible shape memory alloy (SMA) wire is used to throw a lever in a latch. The SMA actuator provides weight and space savings. In one embodiment, the SMA actuator is incorporated in the handle of the latch in order to provide a child lock or double lock function. The handle has a lever which includes a relatively short slot leg and a relatively long slot leg. A toggle sits in the slot. At least one SMA wire is connected to the toggle to move it between the relatively short slot leg, wherein the lever is prevented from pivoting, and the relatively long slot leg, where the lever is enabled to pivot. In another embodiment, the SMA actuator is embedded in the latch itself, and used to throw a lever that controls the child lock function.

An improved electric latch including latch position registration at power loss. A small motor affects a number of independent electrical actuations using an index gear, actuations of: Central Locking, Super Locking, Selective Locking, Power/electrical door opening (Passive Opening), and Power/electrical door closing (Soft Closing). The improved latch uses at least one sensor and several targets positioned on latch hardware to register drive mechanism positions of a latching system after loss of power. The improved system uses a sensor and target specifically for registered function. The present invention avoids the complexity of prior Latch designs by providing for latch position registration.

A power-release door lock system for an automotive door having a latch, including a ratchet (18) and pawl (20), and an electro-mechanical exterior latch release mechanism (220) for actuating the pawl to release the ratchet. The system includes a controller (210) and a pressure sensitive switch (216) mounted to an outside door handle (214) of the automotive door and electrically connected to the controller. The controller is programmed to disable the pressure sensitive switch in response to a predetermined “lock” signal and enable the pressure sensitive switch in response to a pre-determined “unlock” signal, in which case the controller energizes the exterior latch release mechanism to release the ratchet in the event the pressure sensitive switch is actuated. The system eliminates the need for an exterior lock assembly and its attendant inside lock button or rod.
