ABSTRACT:
A motor-vehicle door latch has a housing, a latching fork pivotal on the housing, and a release pawl pivotal on the housing between a latched position retaining the fork in a latched position engaged around a bolt and securing a motor-vehicle door closed and an unlatched position in which the fork can release the bolt and allow the door to open. An inside door handle can move between a center rest position, an end open position, and an end lock position. A bowden cable has a sheath fixed to the housing and a core having a pair of ends one of which is attached to the handle for displacement of another end of the core jointly with the door handle. A locking lever can pivot between a locked position and an unlocked position. A first actuating lever pivotal on the locking lever offset from its axis has one end connected to the other end of the cable core and an opposite end and a second actuating lever pivotal on the housing between an actuated and an unactuated position has a formation engageable with the opposite end of the actuating lever only in the unlocked position of the locking lever. Mechanism between the second actuating lever and the pawl displaces the pawl into the unlatched position on displacement of the second actuating lever into the actuated position.
