Definitions

  • the invention relates to a motor vehicle door lock, with at least one locking mechanism, a release lever for the locking mechanism, a central locking drive, which operates on a central locking lever and an actuating lever.
  • the locking mechanism is usually composed of a rotary latch and pawl, wherein the release lever acts on the pawl.
  • the operating lever may be an external operating lever.
  • an internal operating lever is used at this point.
  • the present invention comprises variants such that an actuating main lever is realized in combination with optionally an external operating lever and an internal operating lever.
  • the operating lever is designed as an external operating lever, this is usually mechanically connected to an outside door handle. The same applies in the event that this is an internal operating lever to which a door inner handle can be connected. If the outside door handle and inside door handle are realized, one usually resorts to an inside operating lever, an outside operating lever and an actuating main lever. In addition, of course, any other embodiments of actuating levers are included.
  • the central locking system can be equipped with an electronic control unit for driving the motor vehicle door lock.
  • the usual operation of the central locking lever is such that, when the central locking lever or locking lever is in the locking position, an action on the (outer) actuating lever corresponds to an idle stroke.
  • an anti-theft device optionally implemented, which prevents in the position "anti-theft on” that is unlocked via the inside door handle and the inside operating lever or actuating main lever, the locking mechanism.
  • pawl and release lever can also be made in one piece.
  • the invention is based on the technical problem of providing such a motor vehicle door lock, which is characterized by a simple and functional design by a comfortable door lock operation.
  • a motor vehicle door lock with at least one locking mechanism, a release lever for the locking mechanism, a central locking drive with drive pulley which engages over eccentric pins in a Gabelausappelung a central locking lever and this pivots either clockwise or counterclockwise, and with a Operating lever, which is provided for the coupling of the actuating lever and release lever rotatably connected to the actuating lever actuating spring, and wherein the actuating spring elastically yielding the actuating lever to the release lever at least in befindlichem in locking position Primaverriegelungshebel and thereby blocked release lever
  • the trigger lever moves against a stop on the central locking lever when the central locking lever is in the locking position, otherwise the lever is connected (ie when the central locking lever is not in the locking position) and release lever predominantly rigid (except for in a lever mechanism basically unavoidable elasticities).
  • the actuating spring realized at this point absorbs pivoting movements of the actuating lever and forwards them to the triggering lever.
  • the release lever in the locking position of the central locking lever through this
  • the actuating spring ensures the described elastically yielding coupling, because it rotationally receives rotational movements of the actuating lever.
  • the ratchet is not unlocked.
  • the trip lever moves in the course of the actuation of the actuating lever in the direction of the functional position "door open” with the central locking lever located in the locking position against the stop on the central locking lever.
  • In befindlichem in unlocking central locking lever of the release lever is pivoted freely by an actuation of the actuating lever regardless of the central locking lever and can unlock the locking mechanism. This is achieved, for example, such that when the central locking lever is in the unlocking position, the spring-loaded triggering lever moves under the abovementioned stop on the central locking lever and the pawl is transferred into the open position.
  • the invention provides that the actuating spring is designed as a leg spring, wherein one of the two spring legs cooperates with an actuating member on the release lever.
  • the external actuating lever is thus not only burdened by a normally provided return spring.
  • a force transmission between the external actuating lever and the release lever is achieved by means of the further provided actuating or leg spring, which is not rigid, but resilient and therefore correspondingly yielding, and Although at least in the locking position befindlichem central locking lever.
  • the actuating spring is arranged regularly in the pivot axis range of the actuating lever. Furthermore, the invention teaches that the (outer) actuating lever has a stop arm or retaining arm for the associated spring leg of the actuating spring, and that the spring leg abuts against the retaining arm without actuation of the release lever with unactuated (external) operating lever. In this way, it is achieved that in befindlichem in unlocking central locking lever, the relevant vehicle door still remains closed and is opened only in the course of actuation of the operating lever and thus the connected outside door handle.
  • the stop arm or retaining arm expediently has a retaining lug for the spring leg of the actuating spring, against which therefore the spring leg rests when the (outer) actuating lever is in its initial position and is therefore not actuated.
  • the release lever is designed as an L-shaped lever, whose one L-leg forms the actuating member for the spring leg of the actuating spring and the other L-leg cooperates with the pawl.
  • the pivoting of the release lever by its application to the spring leg of the actuating or leg spring in the course of actuation of the external actuating lever ensures the pivoting of the associated pawl in the open position and consequently for the release of the rotary latch when the central locking lever in the unlocked position located.
  • the central locking lever located in the locking position blocks the pivotal movement of the release lever, so that then the pawl is in the closed position or remains and locked the catch in the closed position.
  • the stop on the central locking lever may be formed as projecting against the actuator of the release lever arm with stop surface for a stop lug on the actuator or on the relevant L-leg of the release lever.
  • the stop on the central locking lever can also be a stop contour.
  • the stop lug may, as with the retention lug on the restraint arm of the (outer) actuating lever, be merely angled.
  • the invention comprises a variant in which the actuating lever is designed as an external actuating lever and in addition an actuating main lever and a clutch lever are realized. With the help of this clutch lever, an anti-theft device can be realized with the central locking lever in the locking position.
  • a motor vehicle door lock having in its basic structure a rotary latch 1, a pawl 2 and a release lever 3 for the pawl 2, further loaded by a return spring actuating lever 4 and a central locking lever 5.
  • a central locking drive of which only a reversing electric motor 6 with motor shaft 7 and worm wheel 8 are indicated, which meshes with a drive pulley 9, which in turn via eccentric pins 10 in a fork recess 11 of Central locking lever 5 engages and this can pivot either clockwise or counterclockwise (see Fig. 1).
  • the central locking drive is then applied for unlocking the locking mechanism 1, 2 from catch 1 and pawl 2 when an authorized user requests access to an associated motor vehicle door. This can be done keylessly and by simultaneously identifying the user based on their language, voice, eye iris or fingerprint.
  • an actuating spring 12 for the release lever 3 is rotatably connected.
  • the actuation spring 12 presses in the functional position "door open” pivoted external actuating lever 4, the release lever 3 in befindlichem in the locked position central locking lever 5 against a stop 13 on the central locking lever 5 (see FIG .. 4).
  • the spring-loaded release lever 3 underruns the stop 13 so that the pawl 2 is transferred into the open position (compare FIGS. 3 and 5).
  • the actuating spring 12 is designed as a leg spring 12. One of the two spring legs 14 cooperates with an actuating member 15 on the release lever 3. Further, the actuating spring 12 is disposed in the pivot axis range of the outer actuating lever 4 and just connected to the outer operating lever 4 rotatably.
  • the external actuating lever 4 has a stop arm or retaining arm 16 for the associated spring leg 14 of the actuating spring 12.
  • the spring leg 14 is at unconfirmed external operating lever 4 against the retaining arm 16 without acting on the trip lever 3 on.
  • the retaining arm 16 has a retaining lug 17 for the spring leg 14 of the actuating spring 12.
  • the actuating spring 12 couples the actuating lever or external actuating lever 4 and the release lever 3 more or less rigid, as long as both levers 3, 4 can move freely. This is the case in the unlocking position of the central locking lever 5 (see Figures 3, 5, 9 and 12).
  • the actuating spring 12 connects the actuating lever 4 with the release lever 3 elastically yielding when the locking lever 5 is in its locking position. For then the trigger lever 3 is blocked by the locking lever 5, so that the actuating lever 4 rotatably connected to the actuating spring 12 is twisted by pivoting movements of the actuating lever 4 only and the release lever 3 not (more) entrains (see Fig. 1, 2, 4 , 7, 8, 10 and 11). Only when the central locking lever 5 is transferred to its unlocked position, the actuating spring 12 then ensures that the trigger lever 3 follows the previously stored pivotal movement of the actuating lever 4 and the locking mechanism 1, 2 unlocked.
  • the release lever 3 is formed as an L-shaped lever, whose one L-leg forms the actuating member 15 for the spring leg 14 of the actuating spring 12 and whose other L-leg 18 cooperates with the pawl 2.
  • the stop 13 on the central locking lever 5 is as projecting against the actuator 15 of the trigger lever 3 arm with stop surface 19 for a stop lug 20th formed on the actuating member 15 and on the relevant L-leg of the trigger lever 3.
  • the motor vehicle door lock functions as follows:
  • the external actuating lever 4 is inactivated and the central locking lever 5 is in the locked position.
  • the pawl 2 locks the catch 1 in the closed position.
  • the external actuating lever 4 is actuated and acts of the stop arm or retaining arm 16 and its retaining tab 17 released spring leg 14 of the actuating spring 12 on the actuator 15 of the release lever 3, but can the release lever. 3 do not pivot to actuate the pawl 2, because it is against the stop 13 in the locked position located central locking lever 5 is applied.
  • the central locking lever 5 has been transferred into the unlocked position. Consequently, when the external actuating lever 4 is actuated, the triggering lever 3 or its actuating member 15 can now travel under the stop 13 on the central locking lever 5 as a result of the spring leg loading of the actuating spring 12, so that the motor vehicle door lock opens and the vehicle door can be opened.
  • the leg spring is supported on the one hand on the stop arm or retaining arm 16 of the actuating lever 4 on the other hand Twisted because the release lever 3 so far with its on-central locking lever abutment surface 19 abuts against the stop 13 of the central locking lever 5.
  • FIGS. 10 to 12 differs from the embodiment according to FIGS. 7 to 9 essentially in that additionally an actuating main lever 22 and a coupling lever 23 are realized.
  • the actuating main lever 22 is acted upon by a bending (at 24) of the external actuating lever 4 and may be connected via a further fold 25 with a door handle not expressly shown. He follows in the illustrated variant both movements of External actuating lever 4 and the internal actuating lever, not shown.
  • the locking lever located in the central locking lever 5 again ensures that when the outside door handle and thus pivoted clockwise outside door operating lever 4 of the release lever 3 can not act on the pawl 2, insofar as only the leg spring 12 is twisted.
  • the clockwise movement of the external actuating lever 4 is transmitted via the fold or nose 24 on the actuating main lever 22, which performs a counterclockwise movement in the transition from Fig. 10 to Fig. 11.
  • the clutch lever 23 also makes a clockwise movement.
  • the triggering lever 3 can pivot freely because its abutment surface 19 on the stop lug 20 no longer bears against the stop 13 of the locking lever or central locking lever 5. This in turn means that the release lever 3 can lift the pawl 2 with its L-leg 18 in this functional position.
