Abstract

A motor-vehicle door latch has a pivotal latching fork, a release pawl engageable with the fork and displaceable between latched and unlatched positions, and a release lever engageable with the pawl for displacing same between its positions and formed with an elongated slot. An outside actuating lever is provided with an entrainment nose aligned with an end of the release-lever slot. Separate inside and outside locking levers are coupled via a spring to a main locking lever displaceable by the inside and outside levers between a locked and an unlocked position. A link lever pivoted on the main locking lever carries a coupling pin projecting through the slot and engageable with the entrainment nose in the unlocked position of the main locking lever and unengageable with the entrainment nose in the locked position of the main locking lever. The link lever is slidably mounted on the main locking lever and is biased toward the entrainment nose so that on movement of the main locking lever from the locked to the unlocked position with the actuating lever actuated the coupling pin engages the nose and the link lever slides against spring force on the main locking lever.
