1. Motor vehicle door lock which can be locked and unlocked by motor and can be opened both mechanically and also by motor, comprising:

  • a lock mechanism with several interacting elements, including;

    a lock element in the form of a detent pawl, a lock latch which is held in a lock position by the lock element and which is released from the lock position when the lock element is actuated, and a coupling element, wherein said coupling element has;

    a coupled position in which an outside actuating element, when actuated by hand from the outside door handle, actuates the lock element via the coupling element, and a decoupled position in which the outside actuating element, when actuated by hand from the outside door handle, executes an idle stroke; and

    a central interlock drive having a motor for moving the coupling element from the coupled position to the decoupled position and from the decoupled position to the coupled position when the outside actuation element is not actuated, wherein, if actuation of the outside actuating element begins with the coupling element in the coupled position, actuation of the lock element can be obtained mechanically by the operation of the outside actuating element, wherein, if the outside actuating element is already in the idle stroke and the coupling element has not yet reached the coupled position, the coupling element is prevented from reaching the coupled position, but actuation of the lock element can be obtained in that position in a motorized manner by the motor of the central interlock drive; and

    wherein the coupling element is actuable by the motor of the central interlock drive via an adjustment element;

    wherein the coupling element is moveable by motorized actuation from the decoupled position, when the outside actuation element is actuated, into a storage position preceding the coupled position, the coupling element being automatically moveable from the storage position into the coupled position when the actuation if the outside actuation element is not actuated;

    wherein the drive element is connected to a pivot arm which, when the drive element is actuated, pivots in a direction around a pivot axis such that a free end thereof meets said one of the release element and the lock element and actuates it if the coupling element is not in the coupled position, and runs freely if the coupling element is in the coupled position; and

    wherein the adjustment element is a lever which is supported on the pivot arm at a distance from the pivot axis and which, when the pivot arm pivots around the pivot axis, executes an essentially linear motion.
