Definitions

  • Motor vehicle lock in particular motor vehicle door lock
  • the invention relates to a motor vehicle lock, in particular a motor vehicle door lock, with an actuating lever chain with at least one trigger lever and one actuating lever, and with a safety device which mechanically decouples the actuating lever from the trigger lever in its “secured” position and “unlocks” it in its position. both levers mechanically coupled to each other.
  • the safety device In its “secured” position, the safety device thus ensures that the actuating lever chain is interrupted, so that the actuating lever is acted upon against a closed locking mechanism, essentially consisting of a rotary latch and pawl, provided at the end of the actuating lever chain. That is, even when the actuating lever chain is acted upon, the relevant locking mechanism cannot be opened via the mechanically opened or separated actuating lever chain.
  • the safety device assumes its “unlocked” functional position, the actuating lever chain in question is closed and the locking mechanism provided at the end can be opened. To do this, the release lever usually works on the pawl as part of the locking mechanism and ensures that the pawl is lifted from its engagement with the ratchet.
  • the rotary latch then opens with the help of a spring and releases a previously caught locking bolt.
  • the associated motor vehicle door lock and also the motor vehicle door can be opened.
  • Child safety device is designed.
  • the child safety device works on a control lever which, in its engaged position, entrains a locking lever when the actuating lever is triggered and, in its empty position, decouples the locking lever from movements of the actuating lever.
  • the child safety device itself has an eccentric and a pin and can usually be pivoted manually.
  • the invention is based on the technical problem of further developing such a motor vehicle lock and in particular a motor vehicle door lock in such a way that the complexity and the production costs are reduced.
  • a generic motor vehicle lock and in particular a motor vehicle door lock is characterized within the scope of the invention in that the safety device has a clutch slide which is mounted on the actuating lever and can be moved predominantly linearly for the optional mechanical decoupling/coupling of the actuating lever with the release lever.
  • the procedure is such that the clutch slide can be acted upon with the aid of a safety lever as a further component of the safety device.
  • the procedure is also such that the clutch slide is acted upon by a spring in the direction of its "engaged” position.
  • the safety lever in its “secured” position urges the clutch slide into its "disengaged” position against the force of the aforementioned spring.
  • the design is such that the safety lever is designed to be pivotable about an axis via an electric motor drive.
  • the procedure is first of all such that the safety lever, as a component of the safety device, can advantageously be actuated with the aid of an electric motor drive and can be pivoted about its axis.
  • the safety lever can advantageously be actuated with the aid of an electric motor drive and can be pivoted about its axis.
  • manual actuation and activation of the safety lever is also conceivable and is covered by the invention.
  • the safety device can easily be acted upon, for example by remote control, starting from a dashboard.
  • the safety device is generally a child safety device, ie a safety device that is typically used on rear motor vehicle side doors.
  • a child safety device ie a safety device that is typically used on rear motor vehicle side doors.
  • Another advantage according to the invention is that the electric motor drive for pivoting the safety lever about its axis can be implemented and implemented in a particularly simple and compact manner and thus inexpensively.
  • the electromotive drive and the safety lever it is only necessary in the "secured” position of the safety device to press the clutch slide against the force of the spring assigned to it into its “disengaged” position or for the duration of the assumption of the "secured” position. to keep it "disengaged” in this position.
  • the spring in question ensures that the clutch lever is acted upon with its help in the direction of its “engaged” position.
  • the clutch slide can be held in its “disengaged” position easily and with little effort via the electric motor drive and, after the release of the pressure on the clutch slide using the safety lever, it automatically switches to its "engaged” position, supported by the force of the spring.
  • this procedure opens up the possibility of realizing and implementing a so-called "override" function.
  • a single stroke of the actuating lever is sufficient to both unlock and open the motor vehicle lock.
  • the lift in question on the actuating lever may correspond to the fact that the action on the safety lever using the electric motor drive is no longer necessary,
  • the clutch slide is usually guided in a recess in the actuating lever.
  • the clutch slide advantageously has a longitudinal bore through which a guide element on the actuating lever extends.
  • the joint formation of the recess on the one hand and the longitudinal bore on the other hand means that the clutch slide is not only mounted on the actuating lever but can be moved predominantly linearly relative to the actuating lever, as already described in the introduction.
  • the recess in the actuating lever ensures that the clutch slide is guided, which is then additionally supported by the guide element on the actuating lever, which reaches through and overlaps the longitudinal bore in the clutch slide.
  • the safety lever is not only coupled to the electric motor drive, but usually also has a sensor that queries its position.
  • This sensor can be a switch and in particular a microswitch.
  • the design is usually such that the sensor and the electric motor drive are connected to a common control unit. With the help of the control unit
  • control unit can implement and implement any operating commands with regard to the safety device in the sense of "safety device on” or "safety device off”.
  • the desired functional position "safety device on” or “child safety on” corresponds to the control unit acting on the electromotive drive, which in turn swivels the safety lever around its axis so that the clutch slide on the actuating lever is moved against the force with the help of the wasted safety lever the spring is applied so that the clutch slide assumes its "disengaged” position.
  • Any actuation of the actuating lever consequently corresponds to an idle movement relative to the release lever and thus also to the closed locking mechanism. As a result, it cannot be opened.
  • the control unit ensures that the electromotive drive does not pivot the safety lever (anymore). This therefore returns to its initial position or rest position, which can be verified using the sensor querying the position of the safety lever.
  • the spring which acts on the clutch slide in the direction of its "engaged” position ensures that the actuating lever chain is closed, so that a corresponding actuation of the actuating lever is immediately converted into a desired locking mechanism opening, as described. That is, the control unit can release the electric motor drive and thus the safety lever as required, so that when it is acted upon, the actuating lever not only activates the secured one via the clutch slide
  • the safety lever can generally no longer hold the clutch slide in its "disengaged” position against the force of the spring assigned to the clutch slide. That is, the clutch slide goes (automatically) into the "engaged” position, so that any failure of the electric motor drive can be controlled without any problems, because the actuating lever chain closed by this can then be used via the actuating lever and the engaged clutch slide to act on the locking mechanism can.
  • actuating lever chain is designed as an internal actuating lever chain if a child safety unit is implemented. Any external actuating lever chain and its function consequently remain unaffected. This is where the main advantages can be seen.

  • the locking mechanism 1 is in the functional position according to FIG. 1 in its closed state. In this case, the pawl is in locking engagement with the catch.
  • a release lever 2 In order to be able to open the locking mechanism 1, a release lever 2 must be pivoted clockwise about its axis 3, as can be understood in the transition from FIGS. 1 and 2 and further to FIG.
  • the locking mechanism 1 In the functional position according to FIG. 3, the locking mechanism 1 is open, d. H. the pawl was lifted from its locking engagement with the rotary latch using the release lever 2.
  • the rotary latch then opens with the help of a spring and releases a previously caught locking bolt.
  • the locking mechanism 1 and with it the entire motor vehicle lock and an associated motor vehicle door are open.

A mechanical decoupling/coupling of the actuating lever 4 with the release lever 2 takes place with the aid of the clutch slide 5, as will be explained in more detail below.
  • the clutch slide 5 can be acted upon using the safety device 5, 6, 7 and specifically a safety lever 6 as part of the safety device 5, 6, 7.
  • the safety device 5, 6, 7 then also has a sensor 7 that queries the safety lever 6 with regard to its position.

  • a pivoting movement of the safety lever 6 about its axis 10 starting from the functional position in Fig. 7 during the transition to Fig. 8, corresponds to the safety device 5, 6, 7 being "off” from its functional position in Fig. 7 to the in The functional position of the safety device 5, 6, 7 reproduced in FIG. 8 changes to "on".
