Definitions

• the invention relates to a motor vehicle door lock, with at least one actuating lever, further with an anti-theft device, and with a child safety device.
• the actuating lever is regularly an internal operating lever and an external operating lever which can also operate on an actuating main lever. This is not mandatory.
• a motor vehicle door lock of the embodiment described above is known, for which reference is made, for example, to EP 0 826 855 A2. Comparably, DE 199 56 674 A1 precedes.
• the known devices have basically proven, but are structurally complicated and rely on a sauheblige mechanics and several drive motors back. That drives up the costs. This is where the invention starts.
• the invention is based on the technical problem of further developing a motor vehicle door lock of the design described at the beginning in such a way that the overall structure is simplified and thus reduced production costs can be expected.
• a generic Kraft ⁇ vehicle door lock in the invention is characterized in that both aforementioned safety devices are acted upon by a common control, so that either one or both operating lever (internal operating lever and / or external operating lever) go empty (child safety or locking "on") and by the way in the anti-theft position "a" is a locking element without function.
• the motor vehicle door lock has a locking mechanism consisting essentially of catch and pawl, which with the aid of Inside operating lever and / or external actuating lever is opened by, for example, the associated lever with the interposition of a trigger lever lifts the pawl.
• the child safety device designates a unit with the aid of which locks or motor vehicle door locks arranged in particular in the rear can not be opened from the inside. Nevertheless, an occupant is usually able to make an unlocking from the inside to z. B. to let an assistant open the door from the outside. The external operation works unchanged.
• the anti-theft device additionally sets the inner opener or the inner operating lever and the locking element (unlocking from inside and / or outside) out of operation. As a result, even when the window is turned on, it is not possible to transfer an associated motor vehicle door lock to the unlocked state when the theft protection has been inserted.
• the locking element is designed as a central locking element or Be ⁇ part of a central locking unit.
• the interacting both with the anti-theft device and the child safety device control has a pivotable control lever, which has two interacting contours for engagement with a control drive.
• the control drive may have a drive motor, a gear unit and an eccentrically arranged control cam.
• the two interaction contours may be formed as recesses or fork contours and at least have two control surfaces, on the one hand for representing the child safety function and on the other hand for defining the anti-theft function.
• the control cam of the control drive engages the associated control surfaces or dives into the corresponding recesses.
• the control preferably has and in addition to the control lever via a coupling element.
• the coupling element ensures that in the position of the control "child safety off” a continuous mechanical connection of the inner actuating lever or actuating lever is made to the locking mechanism.
• the inside operating lever is formed in detail in two parts with (inner) operating handle lever and (inside) actuating trigger lever, which are coupled and decoupled by means of the coupling element.
• the two previously discussed interaction contours are on the one hand designed as a parental control contour and on the other hand as a theft protection contour.
• the control element is acted upon in each case only in one direction of rotation of the control drive and ensures in this one direction of rotation that the position "child safety on” as well as “anti-theft lock on” are taken up by the pivoting control lever or the control element as a whole , This contributes to the safety of the function because the control drive can always first display the position "child safety on” and only then "anti-theft lock on” in this order.
• the actuating lever works on a locking element, which is additionally provided and whose position is changed by the already mentioned central locking unit or locking device.
• the locking element is guided in a recess of the release lever and interacts with the external operating lever.
• the external actuating lever can open the release lever and consequently the locking mechanism via the aforementioned locking element or the clutch lever. If the motor vehicle door lock is "locked” in its position, the central locking unit and a central locking drive there ensure that the coupling lever or the locking element leaves the previously indicated position. As a result, the external operation lever can not (more) act on the release lever.
• At least two sensors are provided which serve on the one hand to query the control element and on the other hand the control drive.
• a sensor querying the sensors control system is informed at any time about the actual state of the motor vehicle door lock.
• the control drive for the control without reversing the direction of the inserted anti-theft device Do not change the position because the control drive moves to the block when the control lever is in the anti-theft position when energized.
• the associated increase in the current taken up by the control drive or drive motor can be evaluated by the control system.
• the central control lever may be equipped with a locking leg, which cooperates with an associated locking contour. In this way, the manual operation when inserting the child safety device is facilitated and a safe electromechanical triggering guaranteed.
• the presented solution with the central control element or pivotable control lever with two interaction contours first of all convinces by a simple and cost-effective design.
• the presented teaching on the central Steuer ⁇ element back which in turn is applied by means of the control drive.
• the control drive operates in one direction of rotation to "on" the position of child safety and anti-theft device, which further simplifies the functional safety and the structure.
• both the child safety device and the anti-theft device can be operated manually. In the former case, this is ensured by an extension on the child safety lever, which engages in a recess on the central control lever.
• the manual operation of the anti-theft device may accomplish an external locking unit, e.g. B. a lock cylinder, which via an outside locking lever on the zen acts tral control lever, preferably via a cam on the central control lever acts on this.
• the control drive not only has the control cam, but in addition a control disk with an operating contour for the associated sensor.

These movements correspond to pulling movements on the handle 17 to open the motor vehicle door lock. As a result, the release lever 18 is pivoted about its axis B in a clockwise direction and lifts the locking pawl, not shown, of the locking mechanism.
• the child safety device 8 If, on the other hand, the child safety device is to be inserted, the child safety device 8 must be transferred to its "child safety on" position, as can be seen in FIG. 6 as the final state of the movement of the child safety device 8, starting from FIG ,

Firstly, the coupling element 10 is disengaged between the inside operating handle lever 1 and the inside operation tripping lever 2 brought, which therefore received no continuous mechanical connection more.
