Abstract

A motor-vehicle door latch has a housing, a lock fork pivotal on the housing between open and closed positions, a latch pawl pivotal on the housing and engageable with the fork in the closed position to retain it therein and disengageable from the fork to allow to move from the closed to the open position, and an opening lever coupled to the latch pawl and displaceable between an actuated position displacing the latch pawl out of engagement with the fork and an unactuated position with the latch pawl engageable with the fork. A rotary drive couplable to the opening lever can displace it between its actuated and unactuated positions. Structure engageable between the fork and the opening lever decouples the opening lever from the drive on displacement of the fork from the open to the closed position.
