ABSTRACT:
A motor-vehicle door latch has a housing, a latching fork on the housing pivotable into and out of a locked position, a latching pawl engageable with the fork and pivotable into and out of a retaining position holding the lock in the locked position, and a release lever connected to the latching pawl. A main inside actuating lever pivotal on the housing carries a secondary inside actuating lever provided with an actuating pin and pivotal on the main inside actuating lever between a coupling position with the pin engageable with the release lever on pivoting of the main lever and a decoupling position unengageable with the release lever on pivoting of the main lever. An inside door handle connected to the main inside actuating lever can pivot same and, only in the coupling position of the secondary lever, engage the pin against the release lever and displace the pawl out of the retaining position. An integral child-safety assembly including a knob, a shaft fixed on the knob, and a fork fixed on the shaft and engaging directly around the pin is displaceable between an off position holding the pin in the coupling position and an on position holding the pin in the decoupling position.
