ABSTRACT:
A motor-vehicle door latch for use on a vehicle door having a handle and a locking element has a housing, a latch fork pivotal on the housing and engageable in a locking position with a door bolt to retain same and lock the door, an operating lever pivoted on the housing and connected to the handle, a locking lever pivoted on the housing and connected to the respective locking element, and an actuating lever operatively engageable with the fork to release same from the locking position. A link coupled to the locking lever is displaceable thereby between a position coupling the operating lever to the actuating lever for displacement of the fork out of the locking position by actuation of the operating lever and a position decoupling the operating lever from the actuating lever. Thus in the decoupling position actuation of the operating lever will not unlock the door. A central actuator in the latch can displace an antitheft lever into an antitheft position thereof and mechanism between the antitheft lever and the link decouples the locking lever from the actuating lever in the antitheft position of the antitheft lever so that the antitheft position actuation of the inside lever will not be able to release the fork.
