Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism consisting essentially of catch and pawl, further comprising an electric drive for the locking mechanism, and with an actuating lever chain between the electric drive and the locking mechanism, wherein the actuating lever chain with the aid of a manually actuated Notbetutz Incsijns on and disengaged is.
  • Motor vehicle door locks with electric drive for the locking mechanism are known in practice in a variety of configurations.
  • the electric drive ensures the opening of the locking mechanism.
  • the locking mechanism can basically also be opened mechanically. This can be done for example via an internal operating lever.
  • a sensor usually acted upon by the outer door handle ensures that the electric drive is activated.
  • an emergency opening operation is described. This emergency opening operation is run as a function of the signal of a sensor.
  • the sensor may be an airbag sensor that provides a signal in the event of an accident.
  • the electric drive in the known teaching impinges the ratchet not only for electrical opening, but also connects an outside door handle with the locking mechanism to realize an emergency opening.
  • an intermediate lever which can be controlled by the electric drive is provided, which couples a release lever, which can be acted on by the external actuating lever, with the pawl.
  • the intermediate lever in question can be controlled by means of a manually actuatable emergency operating element in the form of a lock cylinder or a comparable mechanical adjusting device in which the release lever with the pawl coupling position transfer.
  • a manually actuatable emergency operating element in the form of a lock cylinder or a comparable mechanical adjusting device in which the release lever with the pawl coupling position transfer.
  • the invention is for this reason the technical problem of further developing such a motor vehicle door lock so that the locking mechanism even in case of failed or blocked electric drive following an opening process can still be converted into its closed state.
  • the emergency closure realized in this way should be implemented with the least possible effort and taking into account a structurally simple design and manual loading.
  • the invention proposes in a generic motor vehicle door lock, that the Notbetuschistselement is arranged in a lock side accessible from the outside area, for example in the inlet mouth.
  • the region accessible to the lock side from the outside means an area of the motor vehicle door lock which is typically accessible from outside in its state installed in the motor vehicle door. Since primarily a so-called manual "emergency closure" is in the focus, in particular areas accessible from the lock side are possible here, which are exposed in the open state of an associated motor vehicle door, in particular for the inlet mouth.
  • the invention is based on the finding that the inlet mouth of a motor vehicle door lock, so the area of the motor vehicle door lock, in which when closing the vehicle door a typically body side mounted locking plunger dips and interacts with the located inside the motor vehicle door lock mechanism, at least in the open state of the relevant Motor vehicle door is accessible.
  • the motor vehicle door lock is placed in the interior of the associated motor vehicle door with recess of the inlet mouth, while the locking pin or an associated lock holder is usually attached to the body side of a B-pillar or C-pillar.
  • the emergency operating element can be integrated as it were in the motor vehicle door lock and stored, for example, in a housing surrounding the motor vehicle door lock housing.
  • An additional external adjusting device in the form of the lock cylinder described in the prior art is expressly not required.
  • the motor vehicle door lock according to the invention can be constructed in a particularly compact, simple and cost-effective manner, and the emergency operating element can be realized in all installation situations of the motor vehicle door lock and is accessible in each case. This applies explicitly not only for side doors of a motor vehicle, but in principle for a tailgate, a bonnet or even a fuel filler flap.
  • the emergency operating element can be acted upon simply and intuitively and manually by an operator in such a way that, with his help, the operating lever chain is usually disengaged.
  • the actuating lever chain is advantageously disengaged by means of the Notbetuschists institutes
  • the previously lifted by means of the actuating lever chain pawl can be returned to its basic position, in which it is usually acted upon spring assisted in the direction of a closed position of the locking mechanism.
  • the locking pin entering via the inlet opening in the motor vehicle door lock ensures that the rotary latch is transferred from its open to the closed position. Since the pawl in the disengaged position of the operating lever chain is not (more) lifted from the catch, it can spring assisted in the Vorrast or main catch of the catch and can close the lock as desired or emergency close.
  • the main benefits are the main benefits.
  • the Notbetuschistselement is designed as, for example, mounted in the inlet mouth Betat Trentsnuss.
  • the emergency operating element or the actuating nut is mounted in the housing of the motor vehicle door lock.
  • the operating nut generally has a front-side actuating slot in which, for example, a screwdriver, a key, a coin, etc. can engage, in order to provide the desired operation.
  • a screwdriver a key
  • the emergency operating element is advantageously equipped with an eccentric. With the aid of the eccentric, the emergency operating element ensures that the actuating lever chain for the described emergency closure is generally disengaged. In this case, the design is also advantageously made such that the emergency operating element largely extends parallel to the actuating lever chain with the eccentric acting perpendicular thereto.
  • the invention is based on the further realization that the inlet mouth and a scaffolding plane spanned by the rotary latch and pawl extend substantially parallel to one another.
  • the operating lever chain is arranged largely perpendicular to this Gesperreebene. Since the emergency operating element extends for the most part parallel to the actuating lever chain, the emergency operating element is consequently arranged predominantly perpendicular to the extension of the inlet mouth and to the scaffolding plane in question. In this way, the eccentric acting perpendicularly thereto, which consequently acts in or parallel to the scaffolding plane, can easily work on the actuating lever chain. In fact, the interpretation is usually made so that the emergency actuator interacts with a clutch lever as part of the actuating lever chain.
  • the clutch lever is generally implemented in addition to two release levers and defined together with these two release levers and essentially the operating lever chain.
  • the clutch lever ensures that the two release levers of the actuating lever chain are mechanically connected to each other in the engaged state and separated from each other in the disengaged state.
  • the clutch lever also has a guide.
  • the clutch lever is advantageously guided by means of at least one release lever. Usually both release levers are equipped with a corresponding guide for the clutch lever.
  • the design is such that the clutch lever interacts in the disengaged state with a housing-fixed stop.
  • the electric drive is generally composed of an electric motor with output shaft and arranged thereon worm.
  • the worm on the output shaft meshes regularly with a gear or an external toothing of a worm wheel realized in this way.
  • the worm wheel is generally equipped with an eccentric cam. Consequently, the electric drive regularly acts on the actuating lever chain via the eccentric cam in question.
  • the electric drive or its worm wheel acts on the first eccentric cam with the eccentric cam located thereon. If the first release lever on the Clutch lever is mechanically connected to the second trip lever, this action with the eccentric cam ensures that the second trigger lever directly lifts the pawl from its engagement with the catch in the closed state of the locking mechanism. As a result, the locking mechanism, which is initially in the closed state, is opened by means of the electric drive.

  • This is possible - as I said - purely mechanically and with the help of the release lever 12.
  • Another way to mechanically open the locking mechanism 1, 2, 3 can be realized such that an unspecified internal operating lever in the opening sense on a boom 8 'of the second trigger lever 8 attacks.
  • the locking mechanism 1, 2, 3 are also opened. Because the counterclockwise movement of the trigger lever 8 ensures that the two previously mentioned trigger levers 12, 13 are acted upon in the sense described and initially the blocking pawl 2 is lifted from the comfort pawl 3. Subsequently, the comfort latch 3 is opened.
