Abstract
A locking device with a holding device for a cover of a motor vehicle trunk is movable in a longitudinal guide and can be held in form-closed manner there by a movable projection. The projection is movable by an operating device and is rotatable about a fulcrum. The operating device includes an electromotive drive and a gear, which can be a non-self-locking gear.
Claims23
Locking device for a motor vehicle, said locking device comprising:
- a projection having a freedom of relative movement in a first direction and in a second opposite direction;
- a holding part to be locked by said projection, said projection and said holding part being movable relative to one another;
- a spring for maintaining the projection in a holding position to provide a holding action by applying a biasing force in the first direction;
- and
- an operating device co-acting with said projection, said operating device including an electromotive drive with a gear for providing relative movement of said projection from the holding position of said holding part in the second direction to a release position for releasing said holding part,
- wherein in the second direction for releasing said holding action, the movement takes place electromotively through said operating device and in the first direction said movement takes place by the force of said spring.
Locking device arrangement for locking and unlocking of an end rod that is movable along a guide so that a cover secured to the end rod is capable of closing a recess in a rear part of a motor vehicle, said locking device arrangement comprising:
- a projection for locking the end rod, said projection being movable in a first direction and in a second direction, said projection and the end rod being movable relative to one another;
- a spring for maintaining the projection in a holding position by applying a biasing force in the first direction;
- and
- an operating device co-acting with said projection, said operating device including an electromotive drive with a gear arrangement for generating movement of said projection in the second direction to a release position away from the holding position, that releases the end rod for movement along the guide,
- wherein movement in the second direction takes place electromotively through said operating device and movement in the first direction takes place by the force of said spring.
Locking device arrangement for locking and unlocking of an end rod that is movable along a guide so that a cover secured to the end rod is capable of closing a recess in a rear part of a motor vehicle, said locking device arrangement comprising:
- a projection for locking the end rod, said projection being movable in a first linear direction and in a second opposite direction, said projection and the end rod being movable relative to one another;
- a spring for maintaining the projection in a holding position for holding the end rod by applying a biasing force in the first direction;
- and
- an operating device co-acting with said projection, said operating device including an electromotive drive with a gear arrangement for generating movement of said projection in the second direction to a release position away from the holding position, that releases the end rod for movement along the guide, said gear arrangement including a toothed wheel and a rack capable of linear motion in response to rotation of said toothed wheel,
- wherein movement in the second direction takes place electromotively through said operating device and movement in the first direction takes place by the force of said spring.
