Abstract
A motor vehicle door lock with a lock latch (4) and a detent pawl (5) which holds the lock latch (4) in the locked position (main catch (4a) and optionally a preliminary catch (4b)) and with a motorized opening drive (6), the motorized opening drive (6) having a drive motor (7) which is preferably an electric motor and has a step-down gear (8) which, on the driven side engages the detent pawl (5) of a detent pawl lever (9) or the like which moves the detent pawl (5) and lifts the detent pawl (5) when the drive motor (7) is triggered accordingly, so that the lock latch (4) is released—opening position. This releasing is optimized with regard to opening forces by a lifting spring (11) being provided which acts in the lifting direction of the detent pawl (5) in association with the step-down gear (8) or the detent pawl lever (9) or the like, so that the lifting spring (11) is tensioned when the opening drive (6) reverses from the open position into the locked position and so that the lifting spring (11) reinforces the opening motion and the lifting motion of the detent pawl (5) with its spring force when the opening drive (6) is advanced from the locked position into the open po…
