Abstract

A motor vehicle door has a removable door outer skin, a module carrier, a door inner skin and a door inner trim. The door inner skin is connected on one side to the removable door outer skin and on the other side to the module carrier. A door inner trim is fixed on a side of the module carrier facing a vehicle interior and at least one guide rail of a cable window lifter is prefitted on the other side of the module carrier. In one of an upper and lower region of the guide rail, a pivotal bearing is provided with a pivotal axis running substantially horizontal and parallel to the door plane for the purpose of prefitting the guide rail on the module carrier. Proximate to the other of the upper and lower regions of the guide rail, a stop face is provided that is associated with a side of the door inner skin which faces the door outer skin.

Claims

1. A motor vehicle door comprising:

a removable door outer skin;

a module carrier;

a door inner skin coupled on one side to the removable door outer skin and on its other side to the module carrier;

a door inner trim is fixed on a side of the module carrier facing a vehicle interior and on a side of the module carrier facing the door outer skin at least one guide rail of a cable window lifter is prefitted, wherein in one of an upper and lower region of the guide rail, a pivotal bearing is provided with a pivotal axis running substantially horizontal and parallel to the door plane for the purpose of prefitting the guide rail on the module carrier and at least a stop face proximate to the other of the upper and lower regions of the guide rail is associated with a side of the door inner skin which faces the door outer skin.

2. The motor vehicle door according to claim 1, wherein parts of the pivotal bearing proximate to the module carrier are integral constituent parts of the module carrier, and wherein the module carrier comprises plastics.

3. The motor vehicle door according to claim 1, wherein parts of the pivotal bearing proximate to the module carrier form a separate unit and are connected to the module carrier.

4. The motor vehicle door according to claim 1, wherein parts of the pivotal bearing proximate to the guide rail are integral constituent parts of one of the guide rail, and a cable guide connectable to the guide rail, and the one of the guide rail and cable guide comprises plastics.

5. The motor vehicle door according to at least one of the preceding claims, wherein the pivotal bearing forms on one side a cylindrical bearing socket which in relation to the pivotal axis has a radially aligned opening with a width which is reduced relative to a bearing bush diameter through which an associated bearing bolt with opposing flattened sides can be inserted, whereby the width of the bearing bolt between the flattened sides corresponds roughly to the width of the radially aligned opening of the bearing socket.

6. The motor vehicle door according to claim 5, wherein the radially aligned opening of the bearing socket points upwards and the flattened sides of the bearing bolt run transversely to the alignment of the opening when the guide rail is located in its useful a first position so that the guide rail can be fitted or dismantled from the pivotal bearing only when it is pivoted at an angle to the module carrier.

7. The motor vehicle door according to claim 1, wherein the pivotal bearing is the sole fixing point proximate to the pivotal bearing and the guide rail.

8. The motor vehicle door according to claim 1, wherein the pivotal bearing forms an end of one of a cable guide and the guide rail.

9. The motor vehicle door according to claim 1, wherein the pivotal bearing is spaced from an upper edge of one of a cable guide and the guide rail, wherein in the module carrier there is sufficient clearance so that when pivoting the guide rail about an angular region required for fitting the guide rail through an opening in the door inner skin, the end of one of the the guide rail at the pivotal bearing side and the corresponding cable guide is not stopped from pivoting against the module carrier.

10. The motor vehicle door according to claim 9, wherein the pivotal bearing serves mainly for prefitting and the one of the guide rail and the cable guide can be fixed in proximate to the pivotal bearing by means of a separate fixing element on the door inner skin.

11. The motor vehicle door according to claim 1, wherein a fixing axis of a fixing spot of the guide rail, which are not formed by the pivotal bearing, run through a cable guide.

12. The motor vehicle door according to claim 11, wherein the fixing axis is identical with a rotary axis of a cable guide pulley.

13. The motor vehicle door according to claim 1, wherein a transport securing device is provided which holds the guide rail in a defined position prior to fitting the module carrier.

14. The motor vehicle door according to claim 13, wherein the transport securing device is provided at a distance from the pivotal bearing.

15. The motor vehicle door according to claim 3, wherein the parts of the pivotal bearing proximate to the module carrier are connected to the module carrier through at least one of screws and rivets.

16. The motor vehicle door according to claim 6, wherein the flattened sides of the bearing bolt run orthogonal to the alignment of the opening when the guide rail is located in the first position.

17. The motor vehicle door according to claim 14, wherein the transport securing device is provided in a region of the other of the upper and lower regions of the guide rail.

18. The motor vehicle door according to claim 14, wherein the transport securing device is provided in the form of a clip-on connection.
