Abstract
A motor vehicle door lock comprises a ratchet locking mechanism, behind the preferably bolt-shaped catch of which there can engage the flanks of two locking teeth which are arranged one behind the other and which are arranged on a pivotable locking lever which is pressed into the locking position by spring pressure and which, upon a movement of the catch relative to the lever during the locking of the door, can be pivoted by the catch against the spring pressure. For the opening of the lock there engages in the locking lever (9) or is secured thereto, a driving member (28), by means of which the locking lever can be removed from the catch (2) to such an extent that the respective abutting tooth edge becomes disengaged.
Claims36
A motor vehicle door lock comprising:
- (a) a catch for attachment to the vehicle door frame,
- (b) a pivoted locking lever for mounting on the door of said vehicle, said locking lever being movable between an engagement position and a disengaged position,
- (c) two teeth on said locking lever provided one behind the other in the direction of relative movement between said catch and locking lever, said teeth being shaped to cooperate with said catch,
- (d) a spring urging said locking lever into a locking position,
- (e) a shaft which when the lock is mounted on the vehicle passes through the vehicle door wall,
- (f) door lock operating means,
- (g) transmission levers between said door lock operating means and said shaft,
- (h) a driving member secured to said shaft, which upon actuation effects a pivotal movement of said locking lever into an unlocked position against the action of the spring, whereby relative movement between the catch and the locking lever to the disengaged position can take place, and
- (i) a spring which urges the driving member into a position in which the driving member is in a rest position in which the locking lever is not operated.
A lock according to claim 33, wherein the relay comprises a bi-stable trigger which is alternately moved into one of the two positions by a current impulse generated by at least one of the switches.
