Abstract:
1. A motor vehicle door lock comprising: a locking mechanism having a locked state and an unlocked state; a locking device comprising a drive motor and a driving worm directly engaging a drive element; at least one actuating element; a release lever pivotable to place the locking mechanism in the unlocked state; and a coupling unit between the at least one actuating element and the release lever, and movable between a first position and a second position, wherein the coupling unit contains a carrier pin engaging in an actuating recess of the at least one actuating element and the coupling unit engaging with the release lever when the coupling unit is in the second position, wherein when the drive element of the locking device is in a locked position, the drive element is placed in an unlocked position by a first traveling movement of the at least one actuating element in a first rotational direction, and the coupling unit is moved to the second position to engage the release lever by a second traveling movement of the at least one actuating element in a second rotational direction opposite to the first rotational direction, wherein the drive element acts directly upon the coupling unit via an actuating contour of the drive element, such that the actuating contour interacts with an actuating pin on the coupling unit, and the drive element and the at least one actuating element share an identical, common axis, which extends through an approximately central main body area of both the drive element and the at least one actuating element.
