Definitions

  • the invention relates to a motor vehicle door lock with the features of the preamble of claim 1 (see. DE-U-8812485).
  • the outer casing of the Bowden cable is connected to the securing lever, while the soul of the Bowden cable is connected to the transmission lever, and can only be stressed in tension.
  • the safety lever By pulling / pushing the outer casing of the Bowden cable, the safety lever can be moved back and forth between the secured position and the unlocking position. If the outer casing of the Bowden cable is in the unlocked position, the transmission lever can be pulled by pulling the soul and the pawl can be actuated (DE-U 8 812 485).
  • This construction corresponds to the motor vehicle door locks operated with a Bowden cable in general (EP-B 0 169 644).
  • the invention has for its object to design and refine the known motor vehicle door lock so that it is more space-saving while maintaining the functions stored on the Bowden cable.
  • the motor vehicle door lock shown schematically in FIG. 1 first has a lock carrier 1 with a lock latch 2 pivotally mounted thereon in the form of a rotary fork latch and a pawl 3 locking the lock latch 2 in the closed position.
  • An entry slot 4 can be seen in the housing-like lock carrier 1, through which a conventional locking block 5 enters in order to engage the lock latch 2 in the door lock.
  • a pawl 6 serving for actuation is located on the pawl 3 and projects laterally from the pawl 3.
  • the pawl 3 is actuated by a transmission lever 8 by means of a force transmission surface 7.
  • a locking lever 9 is provided.
  • the transmission lever 8 and the safety lever 9 are operated together by a Bowden cable 10 (pull / push transmission cable).
  • the transmission lever 8 In the secured position, the transmission lever 8 carries out an idle stroke. In the exemplary embodiment shown, as in the prior art, this is achieved in that the force transmission surface 7 of the transmission lever 8 does not in itself have an overlap with the driving pin 6, that is to say it passes the driving pin 6 when the transmission lever 8 is pivoted.
  • a displaceable (or pivotable) additional lever is also provided, which interacts with a clutch plate 11, which covers both the driver pin 6 and the force transmission surface 7.
  • this coupling plate 11 does in the coupling position; in the uncoupling position, it either does not cover the driver pin 6 and / or the force transmission surface 7.
  • the movement of the clutch plate 11 from the additional lever is controlled by the locking lever 9, so that the clutch plate 11 is in the uncoupling position in the locking position. This is not shown in detail here.
  • Fig. 1 shows the parts of the motor vehicle door lock in the unlocking position, a movement of the transmission lever 8 would be transmitted in this position by means of the coupling plate 11 to the driver pin 6 on the pawl 3.
  • the outer shell 12 of the Bowden cable 10 is fixed to the lock carrier 1 and the core 13 of the Bowden cable 10 is connected to the transmission lever 8 under tension and pressure, so that the transmission lever 8 by means of the core 13 of the Bowden cable 10 in three positions, namely the securing position, the unlocking position and the open position, is adjustable and that the locking lever 9 is not connected to the Bowden cable 10, but is connected via a coupling spring 14 acting in both directions to the transmission lever 8 and can thus be carried by the transmission lever 8 .
  • the interior opening handle also represents an interior security element, thus replacing the door security button. 1 that the safety lever 9 is coupled to an externally operable outer safety element 16, so that securing and unlocking from the outside is also possible here. Of course, this is known per se.
  • the external securing element 16 also defines the end positions of the securing lever 9 at the same time.
  • the illustrated embodiment is characterized in that the locking lever 9 is pivotally mounted on the same bearing axis 15 as the transmission lever 8. This is a structurally particularly simple solution that also minimizes the space required in the castle.
  • the coupling spring 14 is designed as a wrap around the bearing axis 15, fixed on the transmission lever 8, with both legs on a driver pin 17 of the locking lever 9 on both sides.
  • the definition on the transmission lever 8 is realized in that a driver pin 18 is also present near the bearing axis 15.
  • Fig. 1 of the drawing further clarifies that in the embodiment shown here, a central locking drive 19 is fixedly attached to the lock carrier 1, which engages on the locking lever 9.
  • the safety lever 9 is designed here as a two-armed lever.
  • the clutch spring 14 it is advisable to install it with a preload, preferably with a preload of approximately 20 N. Installed with a preload, the clutch spring 14 precisely defines the desired position of the safety lever 9 with respect to the transmission lever 8.
  • a certain bias also has the advantage that, for example, in the case of a hydraulically operating central locking drive 19, this is mechanically moved back from the securing position into the unlocking position by pulling the inner opening handle. In order to overcome the counterforce that occurs in the central locking drive 19, the clutch spring 14 must be able to transmit a minimum force, that is, it must be installed with a minimum preload.
  • a certain maximum tension preferably that of approximately 40 N. This can be done, for example, by limiting the travel, i.e. stops for the levers.
  • Fig. 2 now shows a particularly preferred embodiment, which is characterized in that the central locking drive 19 can be locked in a locking position - anti-theft position - and that the locking lever 9 is divided into two parts, namely an inner part 9a connected to the transmission lever 8 and one with the central locking drive 19 connected outer part 9b, which are coupled via a central locking clutch, in particular a central locking clutch spring 20, that the actuating force of the central locking clutch, in particular the spring force of the central locking clutch spring 20 is greater than the maximum tension of the clutch spring 14 and that engages on the inner part 9a of the outer door lock or the like.
  • Actuatable emergency release lever The principle of operation of such a connection also results, for example, from the prior art; a corresponding coupling spring is expediently also a leg spring.
  • DE-U 8 812 485 for alternatives.
  • the door lock can still be unlocked from the outside by means of the key, at least on the driver's side.
  • the inner part 9a of the locking lever 9 is then moved mechanically and brought into the unlocking position, while the outer part 9b, blocked by the central locking application 19, remains in its position.
  • the central locking clutch spring 20 must of course be “harder” than the normal clutch spring 14 so that this connection normally acts as a solid, one-piece connection.
