Abstract

The invention relates to a motor vehicle door lock comprising at least one actuation lever ( 3 ) that is arranged in a lock housing ( 1, 2 ). Furthermore, a connection means ( 4, 5 ) is used for coupling the actuation lever ( 3 ) to an actuation element ( 6 ) arranged outside the lock housing ( 1, 2 ). Finally, an attachment element ( 2 ) is provided for mounting the connection means ( 4, 5 ) on the lock housing ( 1, 2 ). According to the invention, the attachment element ( 2 ) is designed as a partial housing ( 2 ) which can be combined with a main housing ( 1 ) to form the lock housing ( 1, 2 ) and which, in the mounted state, at least largely covers an opening ( 7 ) in the main housing ( 1 ) as well as a joining zone ( 8 ) between the actuation lever ( 3 ) and the connection means ( 4, 5 ).

First claim

The invention claimed is:

1. Motor vehicle door lock comprising;
a main housing defining an opening, wherein the main housing includes a first side and a second side;
at least one actuation lever arranged in the main housing and accessible through the opening:
a connection means for coupling the at least one actuation lever to an actuation element, arranged outside the main housing, the connection means having a longitudinal axis and wherein the connection means is coupled to the at least one actuation lever at a joining zone;
an attachment element adapted to mount the connection means on the main housing wherein the attachment element is a partial housing that, when mounted on the main housing, is adapted to at least largely cover the opening and the joining zone to form a lock housing;
a socket; and
a pin received in the socket to detachably connect the attachment element to the main housing, wherein the socket and in together form an axis of rotation about which the attachment element can pivot relative to the main housing when installing or removing the attachment element from the main housing, wherein the axis of rotation is substantially perpendicular to the longitudinal axis of the connection means.

2. Motor vehicle door lock according to claim 1 , wherein the attachment element contains a bearing seat for a fixing ring of the connection means.

3. Motor vehicle door lock according to claim 2 , wherein the bearing seat is designed as a slotted seat.

4. Motor vehicle door lock according to claim 2 , wherein the fixing ring contains a fixing groove between fixing flanges surrounding said fixing groove.

5. Motor vehicle door lock according to claim 2 , wherein the bearing seat is designed as a counter bearing for the fixing ring and thus the connection means as a whole.

6. Motor vehicle door lock according to claim 1 , wherein the attachment element has a third side and a fourth side that define an L-shaped cross section.

7. Motor vehicle door lock according to claim 6 , wherein the third side of the attachment element is adapted to form a continued surface with the first side of the main housing when the attachment element is installed on the main housing.

8. Motor vehicle door lock according to claim 7 , wherein an internal surface of the attachment element opposite the third side contains one or more interlocking elements corresponding to interlocking counter elements on the first side of the main housing to secure the attachment element in position on the main housing.

9. Motor vehicle door lock according to claim 7 , wherein the fourth side of the attachment element is adapted to form a continued surface with the second side of the main housing when the attachment element is installed on the main housing.

10. Motor vehicle door lock according to claim 1 , further comprising a fixing pin adapted to secure the attachment element in position on the main housing.

11. Motor vehicle door lock according to claim 1 , wherein the attachment element includes an interlocking element adapted to interlock with corresponding interlocking counter elements on the main housing to secure the attachment element in position on the main housing.

12. Motor vehicle door lock according to claim 1 , wherein the connection means is selected from the group comprising a Bowden cable and a rod.

13. Motor vehicle door lock according to claim 1 , wherein the attachment element is adapted to permit interchanging the connection means between a Bowden cable and a rod.

14. Motor vehicle door lock according to claim 1 , wherein the main housing and the attachment element are formed from the same material.

15. Motor vehicle door lock according to claim 1 , wherein the at least one actuation lever can extend out of the main housing through the opening.

16. Motor vehicle door lock according to claim 1 , wherein the connection means can pivot with the attachment element relative to the main housing when installing or removing the attachment element form the main housing.

17. A motor vehicle door lock comprising:
a main housing defining an opening;
an actuation lever in the main housing, wherein the actuation lever is accessible through the opening;
a connection means for coupling an actuation element located outside the main housing to the actuation lever;
an attachment element that mounts the connection means on the main housing;
a socket; and
a pin received in the socket that detachably connects the attachment element to the main housing;
wherein the socket and pin form an axis of rotation about which the attachment element and the connection means pivot relative to the main housing when installing or removing the attachment element from the main housing;
wherein the attachment element, in combination with the main housing, at least largely covers the opening when the attachment element is mounted on the main housing to form a lock housing.

18. The motor vehicle door lock according to claim 17 , further comprising a fixing pin adapted to secure the attachment element in position on the main housing.

19. The motor vehicle door lock according to claim 17 , wherein the attachment element mounts the connection means on the main housing and wherein the connection means can remain mounted on the attachment element when the attachment element is not mounted on the main housing.
