A motor vehicle lock, especially a tailgate lock in which the opening motion can be triggered by a pure switching measure and then proceeds automatically without fault, preferably without using microswitches. This motor vehicle lock has a lock latch (1) with a front catch (3) and a main catch (4), a detent pawl (6, 6') with a catch projection (9) and an actuating surface (10), as well as a drive element (11) and a driver (12, 12') located thereon. The driver (12, 12') strikes an actuating surface (10) by turning in one direction and lifts the catch projection (9) of the detent pawl (6) out of the main catch (4) and turns off the drive after the lifting process, with the detent pawl (6, 6') remaining in the lifted position. Importantly, the catch projection (9) of the detent pawl (6) overlaps the lock latch (1) on the front catch (3) when the detent pawl (6, 6') is lifted out of main catch (4), and by shifting lock latch (1) into the open position, the detent pawl (6) is moved further into an overtravel position. In the overtravel position, the driver (12) is then released by the detent pawl (6) and is moved into its initial position or another position which no longer influences detent pawl (6). Essentially, a mechanical scanning of the open position of the lock latch is created which makes use of a microswitch superfluous.

[ We claim:] [1.] Motor vehicle lock comprising:a lock latch having front catch and a main catch, the lock latch being movable from an open position into a front catch position and into a main catch position, and from the main catch position into the front catch position and into the open position,a detent pawl having a catch projection and an actuating surface, the catch projection engaging the front catch of the lock latch in the front catch position and engaging the main catch of the lock latch in the main catch position, anda motor drive with a drive element having a driver located thereon, the drive element being rotatable by the motor drive, the drive being positioned so as to strike the actuating surface as a means for lifting the catch projection of the detent pawl out of the main catch, and stop means being provided for turning off the motor drive after the catch projection of detent pawl has been lifted out of the main catch;wherein the catch projection of the detent pawl and the front catch of the lock latch overlap each other when the detent pawl has been lifted out of the main catch and the motor drive stopped by the stop means;wherein, when the lock latch is displaced into the open position, the detent pawl is free to lift into an overtravel position in which the driver is released by the detent pawl and is moved into a position in which it is out of a path of movement of the detent pawl.
