Abstract
The invention relates to a motor vehicle door lock which is equipped with a locking mechanism consisting substantially of a rotary latch and a pawl. A triggering element is additionally provided in order to lift the pawl and thereby open the locking mechanism. The motor vehicle door lock finally comprises an accumulator element which is impinged upon by a spring and which holds the pawl in the lifted position until the rotary latch is opened. According to the invention, the spring and the accumulator element form one component. Furthermore, the spring and the accumulator element are designed as a spring lip which impinges upon the trigger element.
Claims19
A motor vehicle door lock with a locking mechanism comprising:
- a catch movable between a locked position and an unlocked position, wherein the catch comprises a contour,
- a pawl movable between a blocking position where the pawl blocks the catch from moving to the unlocked position and a free position where the pawl does not block the catch from moving,
- a release lever movable between a first position where the release lever does not move the pawl and an unlocking position where the release lever moves the pawl to the free position to lift the pawl off the catch and open the locking mechanism,
- a buffer element movable between a holding position where the buffer element holds the release lever in the unlocking position and a disengaged position where the buffer element does not block the release lever from moving, wherein the buffer element is biased toward the holding position and wherein when the catch moves to the unlocked position, the contour moves the buffer element from the holding position to the disengaged position, wherein, in the free position, at least a portion of the buffer element rests on the release lever which prevents the buffer element from returning to the holding position.

- a pawl movable between a blocking position where the pawl blocks the catch from moving to the unlocked position and a free position where the pawl does not block the catch from moving,
- a release lever movable between a first position where the release lever does not move the pawl and an unlocking position where the release lever moves the pawl to the free position to lift the pawl off the catch and open the locking mechanism,
- a buffer element movable between a holding position where the buffer element holds the release lever in the unlocking position and a disengaged position where the buffer element does not block the release lever from moving, wherein the buffer element is biased toward the holding position and wherein when the catch moves to the unlocked position, the contour moves the buffer element from the holding position to the disengaged position,
- wherein the pawl and the release lever rotate about a common rotational axis.

- wherein the catch and pawl rotate on a first plane and the release lever rotates on a second plane that is spaced apart from the first plane.
