Abstract

A Bowden cable arrangement is provided for a motor vehicle door lock arrangement, wherein the Bowden cable arrangement has a cable strand and a cable conduit, and wherein an adjustment device is provided with a first coupling element and a second coupling element within the chain of operating forces of the cable strand and with a coupling mechanism. In some embodiments the coupling elements may be coupled to each other by the coupling mechanism in different coupling positions relative to each other in order to adjust the length of the cable strand.

First claim

1 . A Bowden cable arrangement for a motor vehicle door lock arrangement, the Bowden cable arrangement comprising a cable strand and a cable conduit, wherein an adjustment device is provided with a first coupling element and a second coupling element within the chain of operating forces of the cable strand and with a coupling mechanism, which coupling elements may be coupled to each other by the coupling mechanism in different coupling positions relative to each other in order to adjust the length of the cable strand.

2 . The Bowden cable arrangement according to claim 1 , wherein the coupling mechanism is of the type of a ratchet assembly with respect to the coupling elements.

3 . The Bowden cable arrangement according to claim 1 , wherein the coupling mechanism may be brought into a coupling state, in which it couples the coupling elements with each other for the transmission of operating forces, and into a decoupling state, in which it decouples the coupling elements from each other.

4 . The Bowden cable arrangement according to claim 1 , wherein the coupling mechanism couples the coupling elements only in a first direction of force between the coupling elements and lets the coupling elements run free in a second direction of force between the coupling elements.

5 . The Bowden cable arrangement according to claim 1 , wherein the coupling mechanism comprises at least one coupling spring, which coupling spring engages the two coupling elements for coupling them in the different coupling positions relative to each other.

6 . The Bowden cable arrangement according to claim 5 , wherein in the coupling state, the coupling spring is in an engagement position and therewith in form fit engagement with both coupling elements and that in the decoupling state, the coupling spring is in a disengagement position and therewith out of form fit engagement from at least one of the coupling elements.

7 . The Bowden cable arrangement according to claim 5 , wherein when driving the two coupling elements into a first direction of force the coupling spring is in engagement with a blocking contour of the first coupling element and a blocking contour of the second coupling element, blocking a relative movement between the coupling elements.

8 . The Bowden cable arrangement according to claim 5 , wherein when driving the two coupling elements into a second direction of force the coupling spring is driven by a driving contour of the first coupling element to come into engagement with a throw out contour of the second coupling element, which throw out contour forces the coupling spring into the disengagement position.

9 . The Bowden cable arrangement according claim 5 , wherein the first coupling element is of oblong design and comprises a plurality of driving contours and/or of blocking contours, which may come into engagement with the coupling spring depending from the coupling position of the coupling elements relative to each other.

10 . The Bowden cable arrangement according to claim 1 , wherein the first coupling element and/or the second coupling element is/are rotationally symmetric with respect to the path of relative movement between the coupling elements.

11 . The Bowden cable arrangement according to claim 5 , wherein the second coupling element comprises at least a first engagement arrangement with a first blocking contour and a first throw out contour and a second engagement arrangement with a second blocking contour and a second throw out contour, which engagement arrangements are spaced from each other along the path of relative movement between the coupling elements.

12 . The Bowden cable arrangement according to claim 11 , wherein the spacing between the engagement arrangements is smaller than the spacing between two adjacent blocking contours of the first coupling element.

13 . The Bowden cable arrangement according to claim 11 , wherein the first engagement arrangement is assigned the first leg of the leg spring and that the second engagement arrangement is assigned the second leg of the leg spring.

14 . A motor vehicle door lock arrangement with a motor vehicle door lock, wherein a Bowden cable arrangement is provided and wherein an actuation movement may be transmitted via the Bowden cable arrangement for operating the motor vehicle door lock, wherein an adjustment device is provided with a first coupling element and a second coupling element within the chain of operating forces of the cable strand and with a coupling mechanism, which coupling elements may be coupled to each other by the coupling mechanism in different coupling positions relative to each other in order to adjust the length of the cable strand.

15 . The motor vehicle door lock arrangement according to claim 14 , wherein the adjustment device is an integral part of the motor vehicle door lock.

16 . The Bowden cable arrangement according to claim 5 , wherein the coupling spring is a wire spring.

17 . The Bowden cable arrangement according to claim 5 , wherein the coupling spring is a leg spring with a spring body and a first leg and a second leg.

18 . The Bowden cable arrangement according to claim 8 , wherein a reset actuation on the coupling spring drives the coupling spring to come into engagement with the throw out contour of the second coupling element, which throw out contour forces the coupling spring into the disengagement position.

19 . The Bowden cable arrangement according claim 9 , wherein the first coupling element comprises a plurality of ring like grooves along its longitudinal extension, each groove being defined by a blocking contour and a driving contour, that the driving contours and/or the blocking contours is/are aligned perpendicularly to the longitudinal extension of the first coupling element.

20 . The Bowden cable arrangement according to claim 11 , wherein the spacing between the first blocking contour and the second blocking contour of the second coupling element is smaller than the spacing between two adjacent blocking contours of the first coupling element.
