Definitions
- the invention relates to a motor vehicle door lock, with a locking mechanism and a closing / opening device, which has at least one drive and a lever drive.
- Cinching / opening devices are generally used for convenience in motor vehicles and serve to either transfer a vehicle door to its fully closed position (main closed position) or to provide for its opening. Due to the not inconsiderable mechanical and cost overhead Zuzieh- / opening devices are nowadays mainly reserved for high-priced automobiles. However, since total safety can also be increased by means of closing aids, an integrated equipment is increasingly being promoted.
- the invention is based on the technical problem of further developing a motor vehicle door lock of the embodiment described at the beginning in such a way that, with a simple and economical construction of the closing / opening device, the possibility of effortless interruption of its function is given at the same time.
- a generic motor vehicle door lock that the lever drive is held in the engaged position by an unactuated release lever and occupies its disengaged position upon actuation of the release lever.
- the lever drive is usually found in engaged position, namely, when the release lever is not actuated. On the other hand, if the release lever experiences an actuation, the lever drive is thereby transferred to the disengaged position and at the same time the mechanical operative connection between the drive and the locking mechanism is interrupted. As a result, the drive can not work (more) on the ratchet and the closing / opening device is switched as it were ineffective.
- the lever drive is designed in two parts. It generally has a support lever and a drive lever. Both the support lever and the drive lever are usually designed as Einarmhebel and equipped at one end with a rotation axis.
- the axis of rotation for the support lever is usually in or on a lock case, which receives the essential elements of the motor vehicle door lock.
- the off-axis free end of the support lever is held between the (unactuated) release lever on the one hand and the drive lever on the other hand.
- the drive lever and the Release lever be equipped with each stop pin, which receive the support lever between them.
- the support lever is generally equipped with an associated spring.
- This spring ensures that the support lever is acted upon, with a force in the direction of contact with the drive lever. As a result, it is ensured on the whole that the support lever, as it were, supports or holds the drive lever, in a position that enables the drive lever to be able to engage the ratchet or a catch of the ratchet there.
- the engaged state of the lever drive corresponds.
- the drive lever is ejected as it were. That is, the drive lever is designed ausierd in disengaged position of the lever drive itself.
- the drive lever is generally connected at one end to the drive and interacts with the other end of the locking mechanism.
- the self-ejecting effect is now preferably achieved by virtue of the fact that the drive lever has a stop surface with a pre-cut or chamfer at its locking-side end.
- the precut or the chamfer is designed so that an already obligatory and the locking associated spring ensures that the drive lever is ejected immediately when the supporting or blocking action of the support lever is omitted because the release lever has been actuated.
- the release lever engages over both the support lever and the drive lever, in its unactuated position.
- the support lever and the drive lever do not become (more) fixed by the release lever or held.
- the rotary latch acting on the stop surface with precut and acted upon by the spring in the direction "open” can eject the drive lever.
- the drive lever with its stop surface is not (more) on the locking mechanism and the closing / opening device can also develop no effect.
- the lever drive is in its disengaged position.
- the release lever effecting its operation by means of its actuation is generally a lock operating lever.
- This lock operating lever may be configured as an inner operating lever and / or an outer operating lever and / or an operating main lever.
- Actuator main lever means an operating lever in the context of the invention, on which both the inner operating lever and the outer operating lever work.
- the inside operating lever is mechanically connected to an inside operation and a inside door handle, respectively, whereas an outside door handle interacts with the outside operating lever.
- an action on the inside door handle and / or the outside door handle ensures that the lever drive is disengaged and the drive lever or a drive pawl realized at this point is released from the locking mechanism because it is itself ejected.
- the locking mechanism returns to its prelocking position when the motor vehicle door lock as a whole is in the "locked” position or even assumes the open position. This applies in the event that the motor vehicle door lock is in the "unlocked” position.
- lock operating lever is sufficient to disengage the lever drive and thus the mechanical operative connection from the drive to the locking mechanism.
- This process is usually associated with an emergency interruption, for example, when a closing process, an object or a hand is trapped between the door and body.
- Fig. 2 shows the object of FIG. 1 in the "disengaged" position of
- Fig. 3 is a perspective view of the motor vehicle door lock total with befindlichem in the main position locking mechanism.
- a motor vehicle door lock is shown, which is composed essentially of a motor vehicle door lock 1 and a cooperating and only hinted locking bolt 2.
- the motor vehicle door lock 1 or the motor vehicle door lock is with a conventional locking mechanism 3, 4 equipped, which is composed of a rotary latch 3 and a pawl 4.
- a schematically indicated drive 5 is realized, which together with a lever drive 6, 7, 8 defines a closing / opening device 5 to 8.
- the closing / opening device 5 to 8 is designed as a closing aid 5 to 8 within the scope of the exemplary embodiment.
- the lever drive 6, 7, 8 is in the engaged position and establishes a mechanical operative connection between the drive 5 and the locking mechanism 3, 4.
- a pulling action on a transmission lever 6 with the aid of a Bowden cable provided in the direction of the arrow in FIG. 1 ensures that a drive lever 7 connected to the transmission lever 6 abuts against the rotary catch 3 of the locking mechanism 3, 4.
- the rotary latch 3 and with it the locking mechanism 3, 4 of the Vorrastsannon of FIG. 1 in the main closed position or main latching position according to FIG. 3 over.
- the rotary latch 3 is moved in the counterclockwise direction, as indicated by an associated arrow.
- a differently shaped connecting means between drive 5 and transmission lever 6 can be used.
- Fig. 1 is the locking mechanism 3, 4 in the Vorschdaledian or Vorrastsander, in which the pawl 4 has fallen into a pre-catch of the rotary latch 3 as is common practice.
- This position has been initiated or achieved that the locking pin 2 is retracted into an inlet mouth of the rotary latch 3 when closing the vehicle door and has pivoted the rotary latch 3 to Vorrastsannon counterclockwise.
- the drive 5 is acted upon as described. That is, via the drive 5 and the transmission lever 6, the drive lever 7 is moved in the illustration of FIG.
- the drive lever 7 is guided by means of a support lever 8, so that the two stop surfaces 7a, 3a on the one hand on the drive lever 7 and on the other hand on the catch 3 remain engaged.
- the drive lever 7 and the support lever 8 are each formed as a Einarmhebel.
- the drive lever 7 is mounted with its one end in a rotation axis on the transmission lever 6. Its other end has the already mentioned stop surface 7a.
- the support lever 8 finds at its one end a pivot bearing in a rotation axis, which is defined in a lock case 9. His other free end is held on the one hand between a trigger lever 10 and on the other hand, the drive lever 7.
- both the drive lever 7 and the release lever 10 each have stop pins 11, 12.
- the stop pin 11 on the drive lever 7 and on the other hand the stop pin 12 on the release lever 10 of the support lever 8 is received, in the "unactuated or not actuated "of the trigger lever 10.
- the drive lever 7 and also the support lever 8 of the release lever 10 are free when it is actuated.
- This operation corresponds to a pivoting of the release lever 10 about its arranged in the lock case 9 axis of rotation D in a clockwise direction, as indicated in Fig. 3 by an arrow.
- the basic structure still includes a merely indicated spring, which acts on the support lever or blocking lever 8 with a force in the direction of engagement with the drive lever 7.
- Another spring which is not explicitly shown, ensures that the locking mechanism 3, 4 or its rotary latch 3 is acted upon in the direction of the "open" position.
- a clockwise force acts on the rotary latch 3 (compare the arrow in FIG. That is, the spring acts in the opposite direction to the movement of the rotary latch 3 during the closing operation (counterclockwise).
- the drive 5 operates on, for example, an output-side Bowden cable or generally a flexible connecting element on the transmission lever 6 and acts on this with a vertical force at one end down, as indicated by a local arrow.
- the other end of the executed as Zweiarmhebel transmission lever 6 is moved upward, which then also applies to the rotatably mounted on the transmission lever 6 drive lever 7.
- the abutment surface 7a of the drive lever 7 strikes directly on the rotary latch 3 (abutment surface 3a) and transfers the rotary latch 3 in the counterclockwise direction to its main latching position (see FIG.
- the motor or drive 5 is stopped. This is the usual functionality of the Zuziehfunktion.
- the release lever 10 has naturally not been actuated, because the motor vehicle door should be closed and not opened.
- the release lever 10 As a result, the release lever 10, the support lever 8 and the drive lever 7 no longer overlap and therefore no longer hold in position, as shown in FIG. 2 reflects. For as soon as the release lever 10 is actuated, this corresponds to the disengaged position of the lever mechanism 6, 7, 8. In this disengaged position of the lever drive 6, 7, 8, the drive lever 7 itself is ejected.
- the stop surface 7a of the drive lever 7 is equipped with a precut or bevel, which rotatably (clockwise) on the rotary latch 3 working said spring ensures that the drive lever 7 from the locking mechanism 3, 4 and the stop surface 3a on the Rotary latch 3 is pushed away.
- the support lever 8 is taken, against the force of the spring. That's it attributed that the spring force of the locking member 3, 4 associated spring exceeds that force that lives in the spring of the support lever 8 and in addition the door seal pressure, the rotary latch 3 presses.
- the drive lever 7 is thus issued upon actuation of the release lever 10 by the force of the locking mechanism 3, 4 associated spring, the back pressure of the door and under an optional entrainment of the support lever 8.
- the drive lever 7 is therefore formed aus-d even as soon as the lever drive 6, 7, 8 assumes its disengaged position when the trigger lever 10 is actuated.
- the actuation of the release lever 10 is - as mentioned - initiated by applying an internal door handle and / or outside door handle.
