Abstract:
Motor vehicle door lock arrangement comprising a detent pawl, and an electrical detent pawl drive for actuating the detent pawl, a control switch for triggering the electrical detent pawl drive, and a lock mechanism with at least one mechanical opening lever which acts on the detent pawl, the detent pawl being actuatable in a normal case only by the electrical detent pawl drive, and in an emergency, being actuatable by a mechanical opening lever;wherein the electrical detent pawl drive is provided with a mechanical energy storage device which is tensioned in a rest position of the detent pawl drive and keeps the opening lever prepared for mechanical activation when a malfunction occurs; and wherein the mechanical energy storage device is connected to the opening lever by a means for causing, upon discharge of energy stored in the mechanical energy storage device, the opening lever to move one of a locking lever and a coupling lever from a locking position in which the detent pawl is isolated into an unlocking position in which the detent pawl is coupled to the opening lever.
