A motor vehicle door lock with a lock mechanism including actuation mechanism which is manually-actuated to actuate a trigger mechanism to a coupled position via a coupling mechanism. A coupling element is engaged by a displacement mechanism which is manually or electronically actuated from the coupled position into an uncoupled position and vice versa when the actuation mechanism is not actuated. When the coupling element is in the uncoupled state and the actuation mechanism is actuated, the coupling element is moved into an intermediate storage position by actuating an adjustment mechanism. A spring element tensions the coupling element into the storage position when the coupling element is shifted. A structural simplification is achieved with the same functionality in that the spring element is an integrated component with the coupling element.

Motor vehicle door lock with elastically deflectable coupling element

A motor vehicle lock with lock elements, such as a rotary latch ( ) and a detent pawl ( ), and with a lock mechanism for controlled actuation of the detent pawl ( ). The lock mechanism has a detent pawl lever ( ), an inside actuation lever ( ), a coupling lever ( ) which couples the inside actuation lever ( ) to the detent pawl lever ( ) or decouples from it, and a central interlock lever ( ). The central interlock lever ( ), on the one hand, can be moved by a central interlock drive into the released position and the locked position, and on the other hand, can be mechanically moved out of the locked position into the release position by actuating the inside actuation lever. The coupling lever ( ) can be moved via the anti-theft lever ( ) into the coupling position and the decoupling anti-theft position. The pivot axis ( ) of the coupling lever ( ) is arranged on the inside actuation lever ( ), at a distance from the pivot axis ( ) of the inside actuation lever ( ), and is not mounted on the lock housing. The pivot axis ( ) of the inside actuation lever ( ) is preferably identical to the pivot axis ( ) of the detent pawl lever ( ).
