Abstract

The invention relates to a vehicle door (1) and to a method for the production thereof. The vehicle door comprises a supporting frame (11) with an opening (2). The supporting frame is joined to a body structure of the vehicle in a manner that permits it to move. The opening (2) is closed in an essentially moisture-proof manner by molding it with a curable compound while forming a supporting plate (10) for accommodating elements such as window lifters, loudspeakers (3) or the like. At least one guide rail for guiding a window pane (9), which can be displaced relative to the supporting frame, is provided for accommodating a lateral edge of the window pane in the supporting plate.

Claims

1. Method for producing an automotive vehicle door, comprising a supporting frame provided with an opening, said supporting frame being connected movably to a body structure of the vehicle, the opening being sealed in an essentially moisture-proof manner by moulding with a curable material whilst forming a supporting plate for receiving elements, such as window winders, loudspeakers or the like, at least one guide rail for guiding a window pane, which is displaceable relative to the supporting frame, being provided in the supporting plate in order to receive a lateral edge of the window pane.

3. Method according to claim 1, wherein the moulding takes place by injection of a thermoplastic or thermoset plastic material.

4. Method according to claim 1, wherein the curable material is PPLGF.

5. Method according to claim 1, wherein the moulding takes place by foaming with a multi-component foaming agent material.

6. Method according to claim 1, wherein the supporting frame is inserted in an injection moulding or foaming tool in order to produce the supporting plate.

7. Method according to claim 1, wherein an outer edge of the opening has a circumferential web for form-fitting and integral connection of the supporting plate to the supporting frame.

8. Method according to claim 1, wherein the opening is completely sealed in order to produce a liquid-proof supporting plate.

9. Method according to claim 1, wherein, after moulding the supporting plate, there is mounted detachably or non-detachably on the side orientated towards the vehicle interior, an interior lining and/or, on the side of the supporting plate pointing towards the vehicle exterior, an external panelling.

10. Method according to claim 1, wherein the supporting frame is cast or produced in a shaping method.

11. Method according to claim 1, wherein the frame is one part or multi-part.

12. Method according to claim 1, wherein merely one opening is provided in the supporting frame which is sealed by the supporting plate.

13. Method according to claim 12, wherein the surface area of the opening, in a ratio to the surface area of the surface area enclosed by the outer contour of the supporting frame, is more than 0.4, preferably more than 0.5.

14. Vehicle door produced according to claim 1.

2. Method for producing an automotive vehicle door, comprising a supporting frame provided with an opening, said supporting frame being connected movably to a body structure of the vehicle, wherein the opening is sealed at least in regions by moulding with a curable material whilst forming a supporting plate for receiving elements, such as window winders, loudspeakers or the like.

16. Vehicle door produced according to claim 2.

17. Method according to claim 2, wherein the moulding takes place by injection of a thermoplastic or thermoset plastic material.

18. Method according to claim 2, wherein the curable material is PPLGF.

19. Method according to claim 2, wherein the moulding takes place by foaming with a multi-component foaming agent material.

20. Method according to claim 2, wherein the supporting frame is inserted in an injection moulding or foaming tool in order to produce the supporting plate.

21. Method according to claim 2, wherein an outer edge of the opening has a circumferential web for form-fitting and integral connection of the supporting plate to the supporting frame.

22. Method according to claim 2, wherein the opening is completely sealed in order to produce a liquid-proof supporting plate.

23. Method according to claim 2, wherein, after moulding the supporting plate, there is mounted detachably or non-detachably on the side orientated towards the vehicle interior, an interior lining and/or, on the side of the supporting plate pointing towards the vehicle exterior, an external panelling.

24. Method according to claim 2, wherein the supporting frame is cast or produced in a shaping method.

25. Method according to claim 2, wherein the frame is one part or multi-part.

26. Method according to claim 2, wherein merely one opening is provided in the supporting frame which is sealed by the supporting plate.

27. Method according to claim 26, wherein the surface area of the opening, in a ratio to the surface area of the surface area enclosed by the outer contour of the supporting frame, is more than 0.4, preferably more than 0.5.

15. Vehicle door, comprising a supporting frame provided with a central opening, said supporting frame being connected movably to a body structure of the vehicle, wherein the opening is sealed in a moisture-proof manner by a supporting plate for receiving elements, such as window winders, loudspeakers or the like, at least one guide rail for guiding a window pane, which is displaceable relative to the supporting frame, by receiving a lateral edge of the window pane, is provided in the supporting plate.
