Abstract

Aspects of the invention relate to a panel for a vehicle interior. The panel includes a relatively non-deformable support having at least one shaped portion, and a relatively deformable inlay pad that can be mounted in the shaped portion. The inlay pad may be formed as a foam pad, as an air cushion and/or as a gel cushion. Aspects of the invention also relate to a method for forming a panel for a vehicle interior.

Claims

1. A panel for a vehicle interior, the panel comprising:

a relatively non-deformable support defining a first portion of a vehicle interior side of the panel that is to be visible from the vehicle interior side, the support being preformed with at least one shaped recess portion that defines a footprint, the shaped recess portion including a recess at least at one edge region of the shaped recess portion; and

a relatively deformable inlay pad defining a second portion of the vehicle interior side of the panel, other than the first portion, and that is constructed separately from the support and that has a size and shape that correspond to the footprint such that the inlay pad itself substantially occupies the footprint of the shaped recess portion, the inlay pad including a foam pad, a decoration layer and an offset, the decoration layer overlying a first surface of the foam pad to be visible from the vehicle interior side, the offset being located below a second surface of the foam pad opposite the first surface, the recess accommodating the offset.

2. The panel according to claim 1, wherein the support includes a sheet joined to the support, the shaped recess portion being formed in the support and the sheet.

3. The panel according to claim 2, wherein the sheet is a decorative sheet, wherein the sheet is formed from a material chosen from at least one of thermoplastic polyolefin (TPO), polyurethane (PU), polyvinly chloride (PVC) or polyacrylonitril-styrene-acrylate (ASA), and further wherein the sheet is formed as a mould skin, a polyurethane spray skin, a polyurethane cast skin, a slush or as an in-mold coating (IMC) slush.

4. The panel according to claim 2, wherein the support is coated by the sheet or the sheet is rear-injected or rear-embossed with the support.

5. The panel according to claim 1, wherein the inlay pad is mounted permanently in the shaped recess portion.

6. The panel according to claim 1, wherein the inlay pad is mounted in the shaped recess portion in a releasable manner.

7. The panel according to claim 1, wherein the inlay pad is mounted in the shaped recess portion with an additional mounting element.

8. The panel according to claim 1, wherein the inlay pad is positively joined to the shaped recess portion and further wherein the shaped recess portion and the inlay pad are formed with a trapezoidal cross-section.

9. The panel according to claim 1, wherein the shaped recess portion is formed into the support as a reinforcing rib.

10. The panel according to claim 1, in combination with a vehicle door, wherein the panel is mounted to the vehicle door.

11. The panel according to claim 1, wherein the foam pad is made of polyurethane (PU), polyethylene (PE), polypropylene (PP), thermoplastic elastomer (TPE), as an air cushion, or as a gel cushion.

12. The panel according to claim 11, wherein the decoration includes a textile, a non-woven fabric, imitation leather or leather.

13. The panel according to claim 11, wherein the inlay pad is joined to the panel via the support element.

14. The panel according to claim 11, further comprising at least one welding dome that is used to mate the inlay pad to the support.

15. The panel according to claim 11, further comprising locking hooks that are used to mate the inlay pad to the support.

16. The panel according to claim 11, further comprising a sensor and/or an actuator for a comfort setting.

25. The panel according to claim 1, wherein the offset extends from the decoration layer.

26. The panel according to claim 1, wherein the offset results from a manufacturing inaccuracy during fabrication of the inlay pad.

17. A method for forming a panel for a vehicle interior, the method comprising:

providing a relatively non-deformable support defining a first portion of a vehicle interior side of the panel, the support being preformed with a shaped recess portion defining a footprint, the shaped recess portion including a recess at least at one edge region of the shaped recess portion;

forming a relatively deformable inlay pad into a shape and size that correspond to the footprint of the shaped recess portion, the inlay pad defining a second portion of the vehicle interior side of the panel, other than the first portion, the inlay pad including a foam pad, a decoration layer and an offset, the decoration layer overlying a first surface of the foam pad and the offset being located below a second surface of the foam pad opposite the first surface; and

then

mounting the deformable inlay pad into the shaped recess portion to substantially occupy the shaped recess portion with the deformable inlay pad itself to form the panel and with the first and second portions of the panel visible from the vehicle interior side, the recess accommodating the offset.

18. The method according to claim 17, wherein the support is coated with a sheet before the inlay pad is mounted thereto.

19. The method according to claim 17, wherein the shaped recess portion is formed in the support by rear-injecting or rear-embossing.

20. The method according to claim 17, further comprising:

coating the inlay pad with a decoration after mounting the inlay pad into the shaped recess portion.

21. The method according to claim 17, wherein mounting the inlay pad into the shaped recess portion comprises riveting, gluing, welding, securing with screws, and or securing with clips.

27. The method according to claim 17, wherein the offset extends from the decoration layer.

28. The method according to claim 17, wherein the offset results from a manufacturing inaccuracy during fabrication of the inlay pad.

22. A panel for a vehicle interior, the panel comprising:

a non-deformable support, the support defining a first portion of a vehicle interior side of the panel and a recessed pad mounting surface defining a footprint, the recessed pad mounting surface being preformed with a recess at least at one edge region of the footprint; and

a pad, that is deformable relative to the support, defining a second portion of a vehicle interior side of the panel, other than the first portion, and that is fully formed prior to being mounted to the pad mounting surface, the pad itself having a size and shape that conform substantially to the footprint such that the recessed pad mounting surface is substantially occupied by the pad, the first portion of the panel visible from the vehicle interior side and the second portion of the panel visible from the vehicle interior side, the pad including a foam pad, a decoration layer and an offset, the decoration layer overlying a first layer of the foam pad to be visible from the vehicle interior side, the offset being located below a second surface of the foam pad opposite the first surface, the second surface being mounted to the recessed pad mounting surface with the recess accommodating the offset.

23. The panel according to claim 22, wherein the offset extends from the decoration layer.

24. The panel according to claim 22, wherein the offset results from a manufacturing inaccuracy during fabrication of the pad.
