Abstract: A power operable door latch and lock mechanism for a vehicle having a central locking system includes a power actuator assembly including an actuating lever drivingly connected to blocking means of the mechanism, a main drive motor for selective powered movement of the lever between locked and unlocked positions, a manual locking lever for operative connection to a non-key controlled manually operable element, and a linkage serving to interconnect the manual lever and actuating lever for manual locking and unlocking independently of the drive motor. The linkage includes a sliding length connected at one end to the actuating lever and having a first guide slot accommodating a connecting pin of the linkage. A rocker arm of the manual locking lever has a second guide slot co-acting with the connecting pin with lost motion for selective transmission of movement of the manual lever to the linkage.
