Single-handle inside actuator for motor-vehicle door latch

Abstract

A motor-vehicle door latch has a latching fork and a release pawl engageable with the fork and pivotal between a latched position retaining the fork and an unlatched position. An inside door handle displaceable between a center rest position, an end open position, and an end locked position is connected to one end of the core of a bowden cable having a sheath fixed to the housing. A first actuating lever pivotal about an axis offset from the locking-lever axis has an arm and is connected to the other end of the cable core for joint movement of the first actuating lever with the inside handle. A second actuating lever pivotal between an actuated and an unactuated position has a formation engageable with the first actuating lever. A first locking lever pivotal about an axis fixed offset from the axis of the first actuating lever between a locked position and an unlocked position is formed with a cutout in which is engaged the arm of the first actuating lever in the rest and locked positions of the inside handle. A second locking lever pivotal also between a locked and unlocked position is permanently coupled to the first locking lever for synchronous movement therewith. The pawl is displaced into the unlatched position on displacement of the second actuating lever into the actuated position and is decoupled from the second locking lever in the locked positions of the locking levers.
