Abstract

A motor vehicle Bowden cable arrangement, in particular for application in the event of and in conjunction with motor vehicle door locks. The Bowden cable arrangement has a core and a sheath which accommodates the core. Moreover, a spring is implemented between the sheath and an abutment. The abutment is formed on or in a support which is preferably mounted flying on the sheath.

First claim

The invention claimed is:

1. A motor vehicle Bowden cable arrangement for a motor vehicle door latch, the motor vehicle Bowden cable arrangement comprising:
a core;
a sheath that receives the core;
an abutment;
a spring between the sheath and the abutment, wherein the abutment is formed on or in a support which is mounted on the sheath in a cantilever manner; and
a collar that surrounds the sheath in an interior of the support, wherein the collar is wholly contained within the interior of the support and is moveable with the sheath to compress the spring, the collar has a surface that extends around and is in direct contact with an axial end of the sheath, and the sheath extends outward from the collar oppositely from the spring;
wherein the collar is of an axial length that specifies a maximum path that the sheath can move inside the support in a direction that compresses the spring, and the axial length of the collar is greater than the maximum path that the sheath can move.

2. The motor vehicle Bowden cable arrangement according to claim 1 , wherein the support is equipped with an extension that receives the core and/or the sheath.

3. The motor vehicle Bowden cable arrangement according to claim 1 , wherein the support surrounds the spring.

4. The motor vehicle Bowden cable arrangement according to claim 1 , wherein the support comprises an opening for the sheath, including the core guided therein.

5. The motor vehicle Bowden cable arrangement according to claim 4 , wherein the opening in the support is arranged opposite an extension.

6. The motor vehicle Bowden cable arrangement according to claim 1 , wherein the support comprises an integrated sensor.

7. The motor vehicle Bowden cable arrangement according to claim 6 , wherein the sensor records movements of the sheath or of the collar receiving the sheath.

8. The motor vehicle Bowden cable arrangement according to claim 1 , wherein the support comprises an adjustable base as the abutment.

9. The motor vehicle Bowden cable arrangement according to claim 1 , wherein the core is connected to a linear actuator.

10. The motor vehicle Bowden cable arrangement according to claim 1 , wherein the support and the sheath are configured for axial movement between the support and the sheath.

11. The motor vehicle Bowden cable arrangement according to claim 1 , wherein the support is formed as a hollow cylinder.

12. The motor vehicle Bowden cable arrangement according to claim 1 , wherein the support has a cylindrical extension.

13. The motor vehicle Bowden cable arrangement according to claim 6 , wherein the collar comprises a projection or contour which interacts with the sensor.

14. The motor vehicle Bowden cable arrangement according to claim 1 , wherein the spring is completely compressed when the sheath reaches an end of the maximum path of travel.

15. The motor vehicle Bowden cable arrangement according to claim 1 , wherein the spring is a helical spring.

16. The motor vehicle Bowden cable arrangement according to claim 6 further comprising a closing drive, wherein the sensor corresponds to a switching signal for deactivating the closing drive.

17. The motor vehicle Bowden cable arrangement according to claim 1 , wherein the spring abuts against the collar oppositely from the abutment.
