Definitions

  • the invention relates to a motor vehicle door lock, with at least one locking mechanism, a first lever, a second lever and a drive unit and with an actuator, wherein with the aid of the drive unit via the actuator both the first lever from a first functional position to a second functional position and the second Lever from a first functional position in a second functional position can be transferred or transferred and vice versa.
  • First lever and second lever generally means different levers within a motor vehicle door latch.
  • the first lever can be a locking lever, in particular a central locking lever.
  • the second lever is usually designed as anti-theft lever.
  • First and / or second lever can also be designed as a child safety lever or as a lever for the operation of a secondary lock.
  • Always means with the first lever and second lever two lever of a motor vehicle door closure, which define at least two (different) lock functions that correspond to their two different functional positions (first functional position and second functional position).
  • the mentioned locking usually consists of a rotary latch and acting on the rotary latch and cooperating with her pawl together.
  • the mentioned locking lever and the anti-theft lever act in a manner known per se with a corresponding locking mechanism and / or actuating mechanism in such a way that the locking lever in its first functional position, for example, "unlocked" a corresponding force action chain (eg., mecanicbetutzskette and / ororgbet2011 Trente) Activation of the locking mechanism releases and in blocked in its locked position (second operating position) or generates a free-stroke.
  • Motor vehicle door locks of the type described above are known from practice in various embodiments, including in addition to the DE 43 43 340 A1 referenced. There, such a motor vehicle door lock is described in which a single electric motor drive operates on both a central locking lever and an anti-theft lever. For this purpose, an output element with eccentric control pin is connected to the reversible electric motor, which engages on the one hand in a fork receptacle of the central locking lever and on the other hand acts on a corresponding control surface on the anti-theft lever.
  • Such motor vehicle door locks have basically proven, but are able to be improved in terms of manufacturing costs. This is where the invention starts.
  • the invention is based on the technical problem of further developing such a motor vehicle door lock in such a way that the most simple and cost-effective design is achieved.
  • the invention proposes in a generic motor vehicle door lock of the type described above, that the first lever via a first coupling element to the actuator and (the first and) of the second lever via a further second coupling element to the actuator are each releasably connected ,
  • the invention thus makes use of two coupling elements, namely a first coupling element and a second coupling element, which in conjunction with the one drive motor of the drive unit ensure that a selective actuation of both the first lever and the second lever succeeds. That is, both the first lever and the second lever can be independently controlled by means of the actuator (and the one single drive motor) in their respective first and second functional position and back.
  • the functionality is therefore the same as if a separate drive motor for the first lever, in particular locking lever, preferably central locking lever, and a second motor for the second lever, in particular anti-theft lever, would be provided. In this way, the already mentioned selective activation and actuation of the first and the second lever with only a single drive motor succeeds.
  • the design is such that the actuator transfers the first lever from its first to its second functional position, wherein during or at the end of this adjustment process, the second lever is in operative connection with the actuator. This is usually accomplished so that during or at the end of the relevant setting process, the first and second lever releasably connecting coupling element assumes its position "engaged". In this position, a renewed action by the actuator causes the second lever is transferred from its first to the second operating position.
  • the actuator by means of the coupling element, the first lever - regardless of an existing or non-existing operative connection of the two levers with each other or the second lever with the actuator - from its first transferred to the second functional position and back.
  • the first coupling element In order to control the second lever from its first to its second functional position and back, regardless of the first lever, the first coupling element is transferred to its disengaged position, so it is ineffective. As a result, the first lever connected to the actuator via the first coupling element is not influenced by corresponding actuating movements on the second lever. Conversely, it has already been explained that the actuator can transfer the first lever with the aid of the first coupling element from its first to the second functional position and back, regardless of an existing or non-existing operative connection of the second lever with the actuator. This is achieved in such a way that the second coupling element connecting the first lever and the second lever occupies only its engaged or disengaged position, but the second lever experiences no influence whatsoever due to the actuating movements in question on the first lever.
  • the two levers can thus be independently and selectively transferred to their two functional positions, and in each case by the actuator performs respective actuating movements in a first or a second direction of movement.
  • the actuating movements of the actuator are initiated by means of the drive unit, which in turn includes a single drive motor.
  • the first coupling element is blocked in its disengaged position by a further adjusting element arranged on the actuator.
  • This actuator is in turn by a contour, for. B. a cam, a web or the like acted on the second lever. That is, the second lever ensures with its contour that regularly connected to the second lever further actuator holds the first coupling element in its disengaged position or blocked. As a result, actuation movements of the second lever initiated by the actuator are not transmitted to the first lever, which retains its position (second functional position).
  • the first lever transferred in the second functional position is not influenced by adjusting movements on the second lever.
  • This is the usual functionality, namely such that the locking lever in the "locked” position permits unimpeded engagement and disengagement of the anti-theft device without any change in the state of the locking lever.
  • the actuator is usually equipped with a first contour and a second contour.
  • the first contour is configured for interaction with the first coupling element and the second contour for interaction with the second coupling element.
  • This allows the actuator to transfer the first lever and the second lever from their respective first functional position in their respective second functional position and back each performs a two-stage movement with associated return to a basic position. That is, the actuator ensures in a first movement step that, for example, the first lever is transferred from its first to the second functional position. Then, the actuator returns to its normal position and thereby allows the second coupling element can connect the first lever and the second lever together and the second coupling element connects the actuator with the second lever. At the same time, the second coupling element takes its engaged position - possibly spring assisted - a. This allows the actuator in the subsequent second movement step in the same direction of movement to control the second lever from its first to the second functional position.
  • the actuator is acted upon in the opposite direction of movement and ensures in a first step that the second lever returns from its second functional position to the first functional position. Subsequently, the actuator resumes its basic position and thereby allows the previously disengaged first clutch is transferred to the position "engaged". Now, in a second movement step, the first lever can be returned from its second functional position to the first functional position in the same (compared to previously opposite) movement direction.
  • 1 to 7 show the motor vehicle door lock according to the invention in different functional positions, wherein in each case with a) a front view and b) a rear view of the associated and reduced to the essential components motor vehicle door lock is designated.
  • a motor vehicle door lock which has a not explicitly shown locking mechanism, for example, rotary latch and interacting with it pawl.
  • the ratchet may be arranged in a plane below that shown in FIGS. 1 to 7 or also perpendicular thereto.
  • an actuating lever chain which is brought into each case by means of the locking or theft protection to be described respectively in engagement or disengagement with the locking mechanism, as has already been described in the introduction and is well known in the art.
  • a first lever 1 which is present and not limiting as a locking lever, in the embodiment of the central locking lever 1, is formed.
  • a second lever 2 in the embodiment and not limiting an anti-theft lever 2, realized.
  • a merely indicated drive unit 3, 4 is composed of a single drive motor or electric motor 3 and an output shaft 4.
  • the drive unit 3, 4 operates or acts on an actuator 5, which is configured in the example and also not restricting as a worm wheel 5.
  • the worm wheel 5 can - following the rotational movements of the electric motor 3 - are acted upon in a clockwise and counterclockwise direction, which indicates a shown in Fig. 1 a double arrow.
  • both the first lever or central locking lever 1 and the second lever or theft prevention lever 2 can be moved from a respective first functional position to a respective second functional position and back, namely selectively, ie, as it were independently from each other.
  • two coupling elements 6, 7 are realized according to the invention.
  • the first lever or central locking lever 1 is detachably connected via the first coupling element 6 to the actuator 5.
  • the second coupling element 7, however, ensures a releasable connection of the actuator 5 with the second lever or theft prevention lever. 2
  • first coupling element 6 is designed as a central locking coupling 6, while the second coupling element 7 assumes the function of an anti-theft clutch 7.
  • Both clutches or coupling elements 6, 7 are each spring-loaded.
  • a central locking clutch spring 8 and on the other hand an anti-theft clutch coupling spring 9 is realized.
  • Both clutch springs 8, 9 are formed as helical springs, wherein a spring arm the respective coupling element or the coupling 6, 7 acted upon and the other spring arm is supported in each case on the first lever or central locking lever 1.
  • an adjusting element 10 which is arranged on the second lever or theft prevention lever 2 and connected thereto.
  • center-zero spring 11 which acts on the actuator or worm wheel 5 and each ensures that the worm wheel 5 spring-assisted assumes its basic position shown for example in Fig. 1 a and 1b. Because each movement of the worm wheel 5 in a clockwise or counterclockwise direction causes the aforementioned center-zero spring 11 is tensioned, because an associated and attached to the worm wheel 5 pin 12 ensures that the two belonging to the center-zero spring spring legs under tensioning the center-zero spring 11 are moved apart.
  • the worm wheel 5, the anti-theft lever 2 and the central locking lever 1 are each rotatably mounted about a common axis 13, the in turn may be set in a lock case or lock housing, not shown.
  • a contour 14 or a pin 14 on the anti-theft lever 2 is important for the operation, which interacts with the rotatable about an axis 15 to the anti-theft lever 2 control element 10, as will be explained in more detail below.
  • first contour 16 or central locking coupling contour 16 a further second contour 17 on the actuator respectively worm wheel 5 is added.
  • This second contour 17 is designed as anti-theft clutch coupling contour 17.
  • the first contour or central locking coupling contour interacts 16 with the first coupling element or the central locking clutch 6, while the second contour 17 or anti-theft clutch coupling contour 17 cooperates with the second coupling element or the anti-theft clutch 7.
  • the insertion of the lock as the anti-theft device is thus initiated by a two-or two-stage movement process of the actuator 5 in a direction of movement (clockwise), wherein the actuator 5 occupies each of its basic position between these two movements.
  • the second lever or theft prevention lever 2 in operative connection with the actuator 5, because insofar the anti-theft clutch 7 for a mechanical connection of both levers. 1 , 2 ensures that the second contour 17 can act on the actuator 5 via the anti-theft clutch 7 on the anti-theft lever 2.
  • the actuator 5 - starting from the functional position of Fig. 3a - the central locking lever 1 of course "locked” by its second functional position back to the first functional position "unlocked” can convict, regardless of whether the anti-theft lever 2 enters into an operative connection with the actuator 5 or not.
  • the actuator 5 - starting from the Fig. 3a - acted upon in a counterclockwise direction, so that the central locking lever 1 is taken by the located in the engaged position central locking clutch 6 in its "unlocked” position and can be.
  • FIGS. 4a, 4b the motor vehicle door lock overall has reached its position “locked” and "secured”.
  • the worm wheel 5 is moved in the counterclockwise direction in FIG. 5a and assumes the position shown in FIGS. 6a, 6b.
  • the worm wheel or actuator 5 takes through the position in the "coupled” anti-theft clutch 7, the anti-theft lever 2 in the position "not secured or unlocked” with. This is shown in FIGS. 6a and 6b, which describe the motor vehicle door lock in the "locked” and “unlocked” positions.
  • the anti-theft lever 2 has its "unlocked" position as shown in FIGS. 6a, 6b and can be unlocked in a second step of the central locking lever 1.
  • the central locking clutch 6 is engaged and thus the first contour 16 or central locking coupling contour 16 abuts the central locking coupling 6.
  • a renewed action on the worm wheel or actuator 5 in the counterclockwise direction transfers the motor vehicle door lock - starting from FIGS. 7a, 7b - into the initial position according to FIGS. 1a, 1b into the position "unlocked” and "unlocked".
