Motor vehicle door lock
First Claim
1. Motor vehicle door lock assembly of the centrally and manually operaable type having a lock latch and detent pawl, a driving journal for actuating of the detent pawl, an inner release lever for manually releasing the door lock assembly from the inside, an outer release lever for manually releasing the door lock assembly from the outside, an inner safety lever and an outer safety lever coupled to the inner safety lever, both of said safety levers being movable between an unlocking position allowing manual unlocking of the door lock assembly and a locking position preventing manual unlocking of the door lock assembly and at least one of said safety levers being in a blocked condition when both of said levers are in the unlocking position and the lock latch and detent pawl are open for preventing manual actuation of the door lock assembly into a locked condition from the inside and from the outside when said lock latch and detent are open, a central lock drive for centrally locking and unlocking the door lock assembly, and a base plate for supporting the entire lock assembly;
- the improvement for enabling central locking of the door lock assembly when said lock latch and detent pawl are open while enabling the inner and outer safety levers to prevent manual locking of the door lock assembly when said lock latch and detent pawl are open, comprising a central lock lever, said central lock lever being engageable and displaceable by said central lock drive as a means for displacement of said one of the inner and outer safety levers from its blocked condition and thereafter for displacement of both of the safety levers into the locking position condition, despite said lock latch and detent pawl still being open, when said central lock drive is actuated for locking of said door lock assembly.

Abstract
A motor vehicle door lock with lock latch (30) and detent pawl (31) with a lock mechanism with a base plate (2), an inner release lever (3), an outer release lever (4), an inner safety lever (7), an outer safety lever (8) coupled with inner safety lever (7), and a central lock lever (9) acting on outer safety lever (8) and able to be connected to a central lock drive. The outer safety lever (8) which is stopped in a released position when the lock latch (30) and detent pawl (31) are open, is mechanically optimized, while taking into consideration the requirements of a multistep locking by a central lock by making the stopping of the outer safety lever (8) disengageable, when lock latch (30) and detent pawl (31) are open, by movement of the central lock lever (9) toward a safety position, so that outer safety lever (8) can then be brought with central lock lever (9) into the safety position.
