Definitions

  • the invention relates to a lock for a motor vehicle door according to the preamble of claim 1.
  • a door lock for a motor vehicle with an outer latch, an inner latch, a locking lever, and a rotatably mounted central locking element for a drive by a central locking drive is known.
  • the central locking element can assume the three angular positions “unlocked”, “locked” and “theft-proof", while the locking lever can assume the two functional positions “unlocked” and “locked”.
  • the central locking element has an eccentric control cam which cooperates with the locking lever such that the control cam blocks the locking lever in the functional position "locked” when the central locking element is in the angular position "theft-proof".
  • the problem here is the emergency release, d. H. if the locking lever is blocked by the control cam in the theft deterrent mode and the central locking drive fails.
  • a complex mechanism is provided which decouples the blocked locking lever of the other lock mechanism, when in the case of emergency unlocking the outer latch is actuated.
  • the Jardinverrieglung to a lock cylinder which can be operated manually with the door key.
  • the anti-theft mode is here understood the functionality that it is not possible to unlock the vehicle by means of the inner latch and to open, ie even with a chosen disc a potential thief can not unlock the vehicle door by operating the inner latch and / or open ,
  • the object of the invention is to overcome the disadvantages known from the prior art and to provide a door lock for a vehicle that is simpler, less expensive and safer.
  • the inner latch acts directly on the locking lever and the outer latch on the central locking element on the locking lever, can be dispensed with a complex mechanical decoupling for emergency release. Rather, the already existing central locking element is used to transmit the movement of the outer lock on the locking lever. By contrast, the internal lock acts directly on the locking lever.
  • the central locking element in the angular position "theft-proof" blocks the locking lever, this can not be spent by actuation of the inner latch in the functional position "unlocked".
  • the central locking element is freely movable between the three angular positions and can thus be brought by the outer latch in one of the three angular positions.
  • the emergency unlocking can thus be carried out by the external locking in case of failure of the same.
  • the central locking element from the angular position "theft-proof” in the angular position "locked” and / or “unlocked” are spent.
  • the vehicle can no longer be unlocked by means of the mecanicverrieglung, but only on the outer latch and in particular a key and an associated lock cylinder, which is arranged externally operable on the vehicle and which is part of the outside lock.
  • the outer lock comprises a lock cylinder which is arranged in the lock housing.
  • the lock can be built compact and theft-proof.
  • DE 197 04812 A1 such a structure is disclosed.
  • the disclosure of the DE 197 04812 A1 is hereby incorporated by reference into the disclosure of this specification.
  • a particularly anti-theft lock can be built.
  • the central locking element preferably has an outer locking cam, which cooperates with the outer locking. This will be the force or the movement the Jardinverrieglung transferred directly to the central locking element.
  • an outer locking rod of the outer latch is connected to the outer locking cam.
  • the connection between the central locking element, in particular the outer locking cam, and the outer locking, in particular the outer locking bar, is advantageous with a predetermined play.
  • a movement that performs the central locking element due to actuation by the central locking drive and / or an actuation by the inner latch be decoupled from the outer latch.
  • These movements of the central locking element are thus not transferred to the other component of the external locking, in particular a lock cylinder.
  • the movement of the outer lock during unlocking or locking must then bridge this game to move the central locking element.
  • the lock on a central locking drive with a motor wherein the motor is connected by gearing with the central locking element.
  • the central locking drive may comprise a plurality of gear elements, in particular gears, which transmit the movement of the motor to the central locking element in one or more stages.
  • actuators suitable that can apply a required movement of the central locking element movement and force directly or indirectly, ie z.
  • connection between the engine of the central locking drive and the central locking element is subject to a predetermined game.
  • a movement of the central locking element due to an actuation of the outer and / or the inner latch are decoupled from the engine, ie an actuation of the outer and / or the inner latch moves only the central locking element, but not the motor. If the motor for driving the central locking element is heavily stunted, the locking forces, if the engine would have to be moved, would be quite high, which is thus avoided.
  • a spring-loaded return element is arranged in the connection between the engine and the central locking element.
  • the drive of the motor can be supported in a certain direction, the return direction.
  • the required motor drive forces or torques can be reduced and the motor can be made lighter.
  • the spring-loaded return element is coupled in a gearbox with the motor and the return element returns when the motor is switched back spring-loaded in a rest position.
  • the central locking drive is always in the same position when the engine is not driven. For an electric motor, this would be the case if it is not energized.
  • the restoring element has a driving cam, whereby the movement of the restoring element is transmitted to the central locking element, wherein the restoring element depending on the position of the central locking element and depending on the direction of rotation of the engine has a certain idling before the central locking element is actuated. This creates a defined clearance between the engine and the central locking element.
  • This embodiment is particularly in connection with the spring-loaded return element, which spends the engine in the off state in a rest position provided. Then, the return element or the engine always has the same starting position when the engine receives a drive signal.
  • the central locking element is free in its movement, especially if it is due to the interior and / or External lock is moved.
  • the motor drives it compensates for the resulting play until the drive cam has "unlocked”, “locked” or “theft-proofed” the central locking element in the desired angular position. After switching off the drive, the restoring element and thus the motor spring-loaded returns to the rest position, while the central locking element remains in the set angular position.
  • the driving cam does not have to act directly on the central locking element, but the movement can also by intermediate transmission elements, for. As gears, levers, etc. are transmitted.
  • control cam cooperates with a control groove in the locking lever.
  • control cam By the control cam is guided in a control groove in the locking lever, precisely defined states of motion between the central locking element and the locking lever can be produced.
  • this may represent a geared coupling such that the angular position "unlocked” of the central locking element and the functional positions “unlocked” of the locking lever or the angular position "locked” and the functional positions “locked” always occur together with central locking element and locking lever.
  • the contour of the cam groove is shaped so that the control cam is in the angular position "theft-proof” to the control groove, that a resultant force of the locking lever on the control cam passes substantially through the axis of rotation of the central locking element.
  • This is essentially achieved in that the contact surface between the cam and control cam is aligned or shaped so that the vertical runs on this contact surface through the axis of rotation of the central locking element. If in this position of the central locking element, the internal locking is actuated with the aim to bring the locking lever "unlocked” in the functional position, acting on the central locking element only forces through its axis of rotation, but none Torques.
  • the locking lever is divided into two parts into a locking lever central part, which cooperates with the control cam, and a locking lever inner part, which cooperates with the inner latch, wherein locking lever central part and locking lever inner part are non-positively connected to each other. This allows a relative movement of the two locking lever parts to each other and / or the arrangement of the two parts at different levels.
  • the locking lever central part and the locking lever inner part advantageously rotate about a common locking lever axis.
  • both parts can be mounted on the axis itself, or a part is rotatably mounted in the other, which in turn sits rotatably on the locking lever axis.
  • the common axis of rotation for both parts can be mounted on the axis itself, or a part is rotatably mounted in the other, which in turn sits rotatably on the locking lever axis.
  • Parts allows a compact design of the two-part locking lever.
  • locking lever central part and locking lever inner part are non-positively connected via a coupling spring.
  • This functionality is particularly advantageous in connection with the locking lever blocked by the control cam when the central locking element is in the angular position "theft-proof". If in this position of the central locking element, the inner latch is actuated with the aim to bring the locking lever in the functional position "unlocked”, the inner latch works against the clutch spring and can indeed be moved, so that the impression of unlocking arises, but it will "Unlocking movement” is not transmitted to the locking central lever part, which is blocked by the control cam.
  • Locking lever central part and locking lever inner part are preferably positively connected via positive locking when the locking lever inner part is moved from the functional position "unlocked” into the functional position “locked” upon actuation of the internal locking system, and locking lever central part and locking lever inner part are frictionally connected via the coupling spring when the locking lever inner part is actuated upon actuation of the internal locking from the functional position "locked” in the functional position "unlocked” is moved.
  • This functionality ensures the function that the Certainlyverrieglung as described above “empty” runs when the control cam in the angular position "theft-proof” the locking lever central part in the functional position "locked” blocks.
  • the lock has an actuating lever, which is actuated by an internal operation and an external operation.

  • the actuating lever acts on a pawl, which in turn releases a catch of the lock and thus allows the door to open.
  • the operating lever is spring-loaded and returns to an operation by the internal or external operation in the starting position.
  • Internal and external operation usually act directly on the operating lever, wherein internal and / or external operation can be made in one piece or in several parts, i. they may also consist of several intermediate elements and levers for transmitting the corresponding actuating movement.
  • the inner operation is usually connected to a manually operable inner handle, which is arranged in the interior of the vehicle, which is preferably in the vehicle door itself.
  • the external operation is usually also connected to a manually operable external handle, which is arranged on the outside of the vehicle, preferably on the vehicle door itself.

  • the inner actuating lever can be rotatably mounted on the lock housing, and transmits the actuating movement of the inner handle of a transmission means to the actuating lever.
  • the lock comprises an inside lock lever as part of the inside lock, the inside lock lever cooperating with the lock lever.
  • the inner locking lever can be rotatably mounted on the lock housing, and transmits the locking movement of an inner locking handle in the same way to the locking lever as previously described for the inside operating lever.
  • the inner actuating lever and mecanical struts cooperate such that an actuation of the inner actuating lever "unlocks” the locking lever from the functional position "locked” in the functional position and vice versa spends.
  • Such a coupling of the two functions "operating" and “locking / unlocking” on the lock has the advantage that in the vehicle interior, only an inner handle and only a transmission means is required to transmit both the manual actuating movement and the locking or unlocking movement , Such an inner handle is for example in the EP 0 169 644 disclosed.

It establishes, as it were, the mechanical connection between the locking mechanism and the actuating mechanism and displaces the actuating mechanism either into the "unlocked” or “locked” functional states.
  • the transmission element is rotatable via a bolt connection with the Locking lever connected. Then, the rotational movement of the locking lever can be transmitted to a longitudinal movement of the transmission element, which, depending on the storage in the lock housing, this longitudinal movement can be superimposed by a rotational movement.
  • the lock has a pawl, in particular for triggering a rotary latch, wherein the transmission element between pawl and an actuating lever is arranged so that in the functional position "unlocked” the operation of the actuating lever is transmitted by means of the transmission element on the pawl, and in the functional position "locked” no transmission of the actuation of the actuating lever is done on the pawl.
  • the transmission element serves to transmit the opening force and the opening movement of the actuating lever to the pawl when the transmission element is "unlocked” in the functional position. In the functional position "locked” the transmission element is so crazy that there is no transmission of the opening movement of the actuating lever on the pawl; the movement of the operating lever and thus also the operation of the inside or outside operation go into the void.

Then the transmission element can be accommodated relatively flat and space-saving in the castle. Where the coupling of actuating lever and pawl is needed to transmit the opening movement, the transmission cam is mounted on the transmission element, so that it can transmit exactly the force between the actuating lever and pawl.

  • the angular position III or Functional position III can only be achieved by acting on the central locking element 17 locking movement V4 of the central locking drive.
  • the functional position II and III of the locking lever 16 do not differ.
  • the transfer cam 32 is in a transfer position "locked” outside the sphere of operation of the actuating cam 34 so that even in the functional position III "theft-proof” of the locking lever 16 is an actuating movement B of the actuating lever as in FIG. 3b shown in the "emptiness” goes and the pawl 4 is not moved.
  • the locking lever 16 is normally moved from the functional position III "protected against theft” into the functional position II "locked” with the unlocking movement E4 by the central locking drive 17 rotates the central locking element in the angular position II.
  • the central locking element 17 can also be brought into the angular position II by means of the unlocking movement E5 via the external locking. This is then done via acting on the outer locking cam 26 outer locking bar 27 and the cooperating lock cylinder. In the two cases, the movement of the central locking element 17 via the control cam 23 and the control groove 24 is transmitted to the locking lever 16.
  • the process corresponds substantially inversely to the locking movement V4 described above.
  • the special function of theft protection consists in the interaction of the control cam 23 and the control groove 24 in the blockage position as already described above. If an attempt is made to "lock out” the locking lever 16 by means of an unlocking movement E6 from functional position III into the functional position II, the profile projection 35 of the locking lever 16 presses on the control cam 23.
  • the direction of the resultant Entriegelungskraft Fe between control cam 23 and profile projection 35 extends slightly offset from the central locking axis 22. This results in the central locking element 17 is a low resulting torque, which would rotate the central locking element 17 in the locking direction V.
  • the central locking element 17 since the central locking element 17 is supported in the angular position III in the locking direction V on the lock housing, the central locking element 17 can not be rotated from its blocking position in the angular position III "theft-proof" by means of unlocking E6.
  • the control cam 23 of the central locking element 17 blocks the locking lever 16, whereby the lock can not be unlocked by the inner latch and thus can not be opened.
  • the locking lever 16 shown is divided into two parts.
  • the locking lever central part 20 the control groove 24 and is accordingly blocked in the functional position III "theft-proof".
  • the locking lever inner part 21 is indeed also rotatably mounted on the same locking lever axis 19, but arranged opposite the locking lever central part 20 rotatable.
  • a rotational force coupling between the two parts takes place by a coupling cam 36 is arranged on the locking lever central part 20, which engages in a coupling groove 37 of the locking lever inner part 21.
  • a coupling spring 38 arranged in the coupling groove 37 presses the coupling cam 36 against a rear wall 39 of the coupling groove 37.
  • FIG. 4b It is shown how the unlocking movement E6 acts on the locking lever inner part 21 by twisting under load of the coupling spring 38 relative to the locking lever central part 20.
  • the unlocking movement E6 goes into the "void".
  • the locking lever inner 21 the functional position I "unlocked” as in FIGS. 2a and 2b has been reached, however, the locking lever central part 20 remains in the functional position III "theft-proof”.
  • the unlocking movement E6 goes into the "void”. Since the transmission element 18 on Locking lever central part 20 is fixed, also the lock remains in the "locked” position, although in FIG. 4b the inside lock is "actuated".
  • the transferable force of the coupling spring 38 is sufficient to "unlock” the locking lever central part 20 at an unlocking movement E1 of the internal locking of functional position II "locked” to functional position I to spend.
  • the locking movement V1 the rear wall 39 of the coupling groove 37 acts directly against the coupling cam 36 so that there is a positive connection between the locking lever central part 20 and locking lever inner part 21.
