Abstract: A mechanically-activated decoupler is used in the actuator of the cinching latch mechanism. The decoupler activates with an input from door handle operation such that the motor drive within the actuator decouples from the remainder of the actuator gear train and latch mechanism whenever the door handle is operated. At rest the actuator is direct-coupled to the latch mechanism having a lost motion provision to allow manual latch function. Because of this the actuator with its motor drive is unloaded and routine door handle-activated decoupling carries little friction. In the event of a power failure during a cinching or release cycle, the handle input activates the clutch and decouples the otherwise binding motor drive of the actuator allowing the remainder of the latch mechanism to return to its at rest state using light return springs. After returning to its at rest state the latch mechanism retains normal manual function until the power failure is corrected.
