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