Abstract

The invention relates to a Bowden cable, particularly for a motor vehicle lock with a locking mechanism, comprising a rotary latch and at least one pawl for locking said rotary latch in a main latching position and a pre-latching position, preferably with a closing aid for moving said rotary latch from the pre-latching position into the main latching position. The Bowden cable comprises a securing device designed such that said Bowden cable can be adjusted and fixed in place by means of a translational movement, or that this adjustment can be fixed by deformation of at least one deformation tab. This allows said Bowden cable to be mounted in a particularly simple manner.

First claim

The invention claimed is:

1. A motor vehicle latch comprising:
a locking mechanism comprising a locking housing, a catch and at least one pawl, mounted on the locking housing, for locking said catch in a main ratchet position and in a pre-ratchet position,
a closing aid for moving the catch from the pre-ratchet position to the main ratchet position,
a Bowden cable comprising a Bowden cable core and a Bowden cable sheath, the closing aid is configured to be operatively connected to a first end of the Bowden cable sheath, said locking housing comprising a connection part that is configured to receive and connected an opposite end of the Bowden cable sheath to the locking housing, the connection part defining a ratchet profile,
a fixing device movably mounted to the connection part, the fixing device defining at least one detent cog that interconnects with the ratchet profile on the connection part, wherein, the Bowden cable sheath contains a connection device, which is received into an opening on the fixing device, for connecting a tool, so as to move the at least one cog of the fixing device with respect to the ratchet profile of the connection part, to a desired position in order to adjust the position of the Bowden cable.

2. The motor vehicle latch according to claim 1 , wherein the adjusting and fixing of the Bowden cable can be achieved by a single translation movement in a tensioning direction.

3. The motor vehicle latch according to claim 2 , wherein the fixing device has at least one detent hook for fixing the adjustment of the Bowden cable, and wherein the connecting part has a guide for retaining the detent hooks and guiding in a translation direction.

4. The motor vehicle latch according to claim 3 , wherein the fixing device contains a fixing means that is releasably attached perpendicularly to the tensioning direction in a translation direction with a positive connection to the Bowden cable core or the Bowden cable sheath.

5. The motor vehicle latch according to claim 4 , wherein at least one detent cog and/or at least one detent hook are arranged on the fixing means.

6. The motor vehicle latch according to claim 2 , wherein the detent cog and/or the ratchet profile have a saw-tooth shape in such a way that the translation movement is only possible in a tensioning direction.

7. The motor vehicle latch according to claim 2 , wherein a guide for retaining the detent hooks and guiding in a translation direction are provided in a connection part.

8. The motor vehicle latch according to claim 1 , wherein the at least one connection devices for connecting a tool for adjustment of the Bowden cable is in the form of a recess.

9. The motor vehicle latch according to claim 1 , wherein the fixing device contains a fixing means consisting of a single piece, wherein the fixing means is releasably attached perpendicularly to the tensioning direction with a positive connection to the Bowden cable core or the Bowden cable sheath by a retaining lug and respective detent opening.

10. A method for installing a motor vehicle latch according to claim 1 , wherein the installation is carried out by:
in a first step, positioning the Bowden cable relatively to the connection part; and
in a second step, adjusting, tensioning and fixing the Bowden cable relatively to the connection part by conducting a single translation movement.

11. Method according to claim 10 , wherein the motor vehicle latch is formed according to claim 6 , prior to the second installation step, the method further comprises an additional installation step for attaching a fixing means to the Bowden cable sheath.

12. Method according to claim 11 , wherein after step two, the adjustment can be corrected by carrying out the additional installation steps
releasing the fixing means,
readjusting the Bowden cable and
reattaching the fixing means.
