Abstract

A combined trim panel and water shield includes a water shield having opposite first and second surfaces, and is of a size and shape to generally conform to a door panel and a trim panel to be protected. The trim panel is configured to cover a vehicle door panel and has a first surface configured to face an interior compartment of the vehicle and a second surface opposite the first surface. A first sealing layer, applied in a predetermined pattern, engages the first surface of the water shield and the second surface of the trim panel. A second sealing layer, applied in a predetermined pattern, engages the second surface of the water shield. In a further aspect, a sealing system is provided for application to a vehicle interior trim panel to prevent the entry of water or dust into an interior compartment of the vehicle. The system includes a trim panel configured for covering a vehicle door panel wherein the trim panel has a first surface configured to face an interior compartment of the vehicle and a second surface opposite the first surface. At least one compressible sealing member engages the trim panel and provides a sealing interference between the vehicle door panel and the trim panel when the trim panel is installed on the door panel.

Claims

1. A method for sealing a vehicle trim panel mounted to a vehicle door panel against entry of water or dust, comprising:

providing a trim panel;

attaching a compressible water shield adapted to be disposed between the door panel and trim panel against the trim panel;

attaching at least one compressible sealing member to the water shield;

installing the trim panel and water shield and sealing member onto the vehicle door panel; and

compressing the sealing member and water shield to form sealing interference between the trim panel and the vehicle door panel.

2. The method of claim 1, wherein the at least one sealing member comprises a compressible gasket engaging a peripheral edge of the trim panel.

3. The method of claim 2, wherein said gasket does not completely circumscribe the trim panel.

4. The method of claim 2, wherein said gasket completely circumscribes the trim panel.

5. The method of claim 2, further comprising a second sealing member engaging the trim panel and, when the trim panel is installed on the door panel, providing a sealing interference between the vehicle door panel and the trim panel.

6. The method of claim 5, wherein the second sealing member circumscribes one or both of an opening in the trim panel and an opening in the door panel.

7. The method of claim 1, wherein the door panel comprises a generally flat portion which is aligned with and sealingly engages the one or more sealing members when the trim panel is installed on the door panel.

8. The method of claim 1, wherein the trim panel comprises one or more pressure ribs engaging the one or more sealing members.

9. The method of claim 1, wherein the sealing member comprises a compressible foam material.

10. The method of claim 1 further comprising:

applying a release coated protective liner over the sealing member; and

removing the protective liner prior to the step of installing the trim panel and water shield and sealing member to the vehicle door panel.

22. The method of claim 1, wherein the sealing member is a removable pressure-sensitive adhesive.

23. The method of claim 1, wherein the sealing member is a generally permanent pressure-sensitive adhesive.

24. The method of claim 1, wherein the sealing member is compressible forming a compression-type gasket when the trim panel is attached to the vehicle door panel.

25. The method of claim 1, wherein the sealing member is a compressible formed-in-place gasket.

26. The method of claim 1, wherein the water shield is a foam material.

27. The method of claim 1, wherein the water shield is an open-cell foam material.

28. The method of claim 1, wherein the water shield is a closed-cell foam material.

11. A sealing system for application to a vehicle inner door panel for preventing water or dust from entering an interior compartment of the vehicle, comprising:

a trim panel having a first surface configured to face an interior compartment of the vehicle and a second surface opposite the first surface;

a compressible water shield adapted to be disposed between the vehicle door panel and the trim panel and against the first surface of the trim panel; and

a sealing member engaging the water shield and the vehicle door panel and providing a sealing interference between the vehicle door panel and the trim panel when the sealing system is installed on the door panel.

12. The sealing system of claim 11, wherein the sealing member is an adhesive.

13. The sealing system of claim 11, wherein the sealing member is a removable pressure-sensitive adhesive.

14. The sealing system of claim 11, wherein the sealing member is a generally permanent pressure-sensitive adhesive.

15. The sealing system of claim 11, wherein the sealing member is compressible forming a compression-type gasket when the trim panel is attached to the vehicle door panel.

16. The sealing system of claim 11, wherein the sealing member is a compressible formed-in-place gasket.

17. The sealing system of claim 11, wherein the water shield is a foam material.

18. The sealing system of claim 17, wherein the water shield is an open-cell foam material.

19. The sealing system of claim 17, wherein the water shield is a closed-cell foam material.

20. The sealing system of claim 11, further comprising a release coated protective liner applied over the sealing member for removal prior to the installation of the trim panel to the vehicle door panel.

21. The method of claim 11, wherein the sealing member is an adhesive.
