Definitions

  • the invention relates to a motor vehicle door lock, with a locking mechanism consisting essentially of catch and pawl, and with an interacting with the catch and / or the pawl intermediate element which transmits movements of the locking mechanism to a sensor, according to the main patent application DE 103 20 442.3 ,
  • the main locking position of the catch or the locking mechanism is also used to switch off a drive for an associated motor vehicle door. This need arises with increasing importance in that more and more sliding door drives are used. With these you want to prevent the obligatory electric motor is unnecessarily burdened by a ride on block. In addition, associated mechanical noise is increasingly bothersome.
  • the invention is based on the technical problem of further developing a generic motor vehicle door lock in such a way that a flawless signal delivery by the sensor is ensured with a simple and compact construction.
  • the invention proposes in a generic motor vehicle door lock that the intermediate element has at least one controlled by the rotary latch and their movements storing rotary latch spring element and acted upon by the pawl pawl element whose combination movement is evaluated by the sensor, or vice versa.
  • the procedure can be reversed by the pawl is assigned a spring element (then called pawl spring element) and the rotary latch a rotary latch element whose coherent movement (combination movement) is evaluated by the sensor.
  • Decisive are therefore a spring element which stores movements and an element that follows the movement, on the one hand the catch and on the other hand the pawl, or vice versa.
  • the associated movement of both elements is evaluated by the sensor to derive a signal about the functional state of the locking mechanism.
  • the intermediate element is therefore initially formed in two parts, with pawl element (pawl spring element) and rotary latch spring element (rotary latch element).
  • the rotary latch spring element is controlled by the rotary latch, while the pawl takes over the loading or control of the pawl element (or vice versa, as already described). Since both the above elements, So rotary latch spring element and pawl element taken together define the intermediate element, they carry out an interconnected movement, the combination movement, from.
  • the rotary latch spring element releases the energy connected and recorded with the stored movement of the rotary latch only after sweeping over a predetermined actuation path of the pawl.
  • This release of energy regularly leads to an associated movement of the rotary latch spring element, which ultimately triggers the sensor or transfers it to a state other than the existing functional state.
  • This delayed sensor release as a result of the rotary latch spring element provided according to the invention has the advantage that the energy stored in the rotary latch spring element and the time of its delivery, thus the triggering of the sensor, can be preset externally. It is conceivable here to relieve the correspondingly biased rotary latch spring element by a lever or the like.
  • this provides the pawl element, so that as a result of this queried by the pawl element movement of the pawl ultimately the release of stored in the rotary latch spring element
  • the kinetic energy of the rotary latch pretends and therefore the mostly connected triggering of the sensor.
  • the invention proposes in this context that when entering into the locking mechanism locking bolt or in the course of taking the closed position on the part of the locking device queried by the sensor rotary latch spring element his occupied in the open position of the locking defined initial position substantially until, until the pawl element ensures a change of motion in the end position.
  • the pawl element triggers a blockade of the rotary latch spring element in this initial position when taking the closed position of the locking mechanism, so that the rotary latch spring element can leave the initial position by the kinetic energy stored in it from the rotary latch and moves into an end position.
  • This change of the rotary latch spring element from the initial position to the end position is detected by the sensor as a switching signal and can be evaluated, for example, as taking the Haupttrastposition the Gesperres.
  • the pawl element thus blocks the rotary latch spring element in the above-mentioned initial position until the pawl element controlling the pawl element reaches a predetermined position.
  • the rotary latch spring element In this predetermined position of the pawl, which follows the pawl member, the rotary latch spring element is released and leaves its previously blocked initial position. As a result, the rotary latch spring element assumes the end position in a spring-assisted manner, because the kinetic energy received by the rotary latch and stored in the rotary latch spring element becomes free after the blockade has been released and the rotary latch spring element is transferred from the initial position to the end position.
  • the rotary latch element is formed in two parts with spring and Abfragarm, wherein the spring accumulator stores relative movements of the rotary latch relative to the Abfragarm as kinetic energy.
  • this kinetic energy can be recorded and stored consequently, it is necessary to hold the Abfragearm against the particular moving during the closing process of the locking catch.
  • the pawl element regularly ensures this blockage of the interrogation arm.
  • the pawl element is preferably designed as a non-rotatably connected to the pawl control lever.
  • the associated pivoting of the pawl ensures that the rotatably connected to the pawl control lever also pivots and blocks the rotary latch spring element or its Abfragearm.
  • the interrogation arm can no longer move with respect to the rotary catch moving further in the course of taking the closed position of the locking mechanism, so that the desired relative movement takes place between the rotary latch spring element or its interrogation arm and the spring accumulator resting against the rotary latch.
  • the further movement of the rotary latch in the spring accumulator is converted into stored energy or tension energy of the spring accumulator.
  • This tension energy or stored energy is only released when the control lever or the pawl element, the blockage of the rotary latch spring element in the course of taking the closed position of the locking ceases. This is usually the case when the pawl is in its primary ratcheting position or just before it.
  • both aforementioned elements have mutually interacting contact surfaces which come into engagement with each other in the course of taking the closed position of the locking mechanism.
  • the senor which is usually a switch or microswitch, is mounted together with the rotary latch spring element in a housing or housing cover of the motor vehicle door lock.
  • the pawl usually experiences together with the pawl element or control lever and the catch a storage in a lock case.
  • the sensor can be placed topologically above the lock case in the housing and / or cover, whereby the required space undergoes a slimming.
  • this arrangement ensures to be able to represent a particularly narrow door lock.
  • housing and cover (and possibly also the lock case) can of course also unite to form a single component.
  • a motor vehicle door lock which convinces not only by a particularly slim and thus compact design, because the intermediate element is pivoted quasi perpendicular compared to the locking mechanism and is arranged in a plane perpendicular to the Gesperreebene intermediate element level, but at the same time the reliability is increased.
  • the intermediate element according to the invention which essentially consists of rotary latch spring element and pawl element composed that the triggering time of the sensor can be set practically variable.
  • the design will be such that the sensor receives a signal shortly before reaching the main stop.
  • this sensor signal can be evaluated, for example, to switch off a door drive.
  • the invention exploits the "momentum" built up, for example, when closing the motor vehicle door, in order to complete the residual travel of the pawl to reach the main catch. Mechanical loads on the drive such as the locking mechanism are thereby reduced or kept in a predetermined framework. The noise is minimal.

  • the locking mechanism 3, 4 consists largely of a rotary latch 3 and a pawl 4, which engage in a known manner.
  • the locking pin 2 may be located on the body for example, on a B-pillar of a motor vehicle, while the door lock 1 is installed in a sliding door. Of course, the reverse can also be done.
  • an intermediate element 5, 6, 7 and a sensor 8 are of particular importance for the present invention.
  • the intermediate element 5, 6, 7 transmits movements of the locking mechanism 3, 4 to the sensor 8 able to transmit certain functional positions of the locking mechanism 3, 4 to a control system, not shown.
  • a signal is emitted as soon as the ratchet 3, 4 in the main ratchet position after Fig. 4 located.
  • the sensor 8 receives the addressed signal even if the position after Fig. 5 is taken with completely fallen into the catch 3 ratchet 4.
  • the output from the sensor 8 signal is evaluated in the control system to stop a drive motor for the associated motor vehicle door and not shown.
  • this motor vehicle door is by way of example and not limited to a sliding door and the drive is a sliding door drive.
  • the inertia is used when closing the sliding door to the locking mechanism 3, 4 - without drive - from the position Fig. 4 in the position accordingly Fig. 5 to convict.
  • the closing process can be completed particularly noiseless and hard mechanical stops are avoided.
  • the intermediate element 5, 6, 7 is in the context of the embodiment of the already mentioned rotary latch spring element 5, 6 and a pawl element 7 together.
  • the rotary latch spring element 5, 6 is acted upon by the rotary latch 3, whereas the pawl element 7 movements of the pawl 4 follows because pawl element 7 and pawl 4 are rotatably connected to each other and coaxially rotate about a common axis A 1 .
  • the catch 3 rotates about an axis A 1 and parallel only indicated axis A2.
  • the intermediate element 5, 6, 7 transmits the movements of the locking mechanism 3, 4 to the sensor 8, in which it rests with its rotary latch element 5, 6 on the rotary latch 3.

  • the rotary latch spring element 5, 6 is formed in two parts with spring accumulator 5 and 6 Abfragarm, the spring accumulator 5 stores relative movements of the rotary latch 3 relative to the Abfragearm 6 as kinetic energy.
  • the Abfragarm 6 can perform pivotal movements relative to an axis B, which is substantially perpendicular to the axis A 1 of the pawl 4 and the pawl element 7 and thus also the axis A 2 of the rotary latch 3.
