Abstract
A motor vehicle lock, preferably an electrically actuatable motor vehicle lock, comprising a locking mechanism with a rotary latch and at least one pawl, a release lever, an electric drive unit, wherein the release lever can be actuated by the electric drive unit, and the locking mechanism can be unlocked by the release lever, also comprising a release aid, wherein additional momentum for unlocking the locking mechanism can be guided into the locking mechanism by means of the release aid, the additional momentum can be generated using the electric drive unit.
Claims15
A motor vehicle lock that is electrically actuatable, the motor vehicle lock comprising:
- a locking mechanism with a rotary latch and at least one pawl;
- a release lever;
- an electric drive unit, wherein the release lever is actuated by the electric drive unit and the locking mechanism is unlocked by the release lever;
- and
- a release aid, wherein additional momentum for unlocking the locking mechanism is introduced into the locking mechanism by the release aid, wherein the additional momentum is generated using the electric drive unit,
- wherein the release lever has a first lever arm interacting with the drive unit and a second lever arm acting on the locking mechanism, a further lever arm being provided which interacts with the release aid, the further lever arm being connected at least to the second lever arm in a non-twisting manner;
- wherein the electric drive unit incudes a first gear stage that interacts with the first lever arm of the release lever, and the release aid includes a second gear stage that interacts with the further lever arm, wherein the first gear stage meshes with the second gear stage;
- and
- wherein the first gear stage includes a first gear wheel and toothing that extends from the first gear wheel, the first gear wheel being positioned in a different plane of rotation from the second gear stage, and the second gear stage meshes with the toothing of the first gear stage.
