Decorative arrangement for an interior lining of a motor vehicle and method for producing same

Abstract

A decorative arrangement for an interior lining of a motor vehicle has a carrier layer (20), a decorative layer (6) on the carrier layer (20), and a protective layer provided on the decorative layer (6). The decorative layer (6) is composed of a wood or wood veneer material. A metal structure (8) is provided on the decorative layer (6). The metal structure (8) is inlaid into the decorative layer (6).

Claims

1. A decorative arrangement for an interior lining of a motor vehicle comprising: a vehicle dash board or door panel including a plastic carrier layer; a decorative layer provided on the carrier layer; a protective layer provided on the decorative layer; the decorative layer further comprised of a wood or wood veneer material; a metal paste structure is provided on the decorative layer, the metal paste structure is inlaid into the decorative layer.

2. The decorative arrangement according to claim 1, wherein the metal paste structure provides metal strips with a maximum width of 0.5 mm.

3. The decorative arrangement according to claim 1, wherein the protective layer is produced from a transparent lacquer.

4. The decorative arrangement according to claim 1, wherein the decorative layer has a lamination facing away from view.

DETAILED DESCRIPTION

(6) FIG. 1 shows a schematic view of a dashboard 2, known per se, with a decorative arrangement 4 according to the disclosure. This has what is known as a “mesh” look. For this purpose, a metal structure 8 is inlaid into a decorative layer 6. The decorative layer 6 is composed of a wood veneer material. The metal structure 8, in this case, is constructed of metal strips with a minimum width of 0.2 mm. The metal structure 8 is produced using a metal paste 22 (see FIG. 3), known per se, by filling a decorative structure 10 with injection-compression molded grooves 11 (see in particular FIG. 2).

(7) FIG. 2 shows a schematic view of the decorative arrangement 4 in an injection-compression molding tool 12. As described above in reference to FIG. 1, the decorative arrangement 4 has a decorative layer 14 made of a wood veneer material. On the side facing away from view, the decorative layer 14 has a lamination 16, in a known manner. On the visible side, a lacquer layer 18 is provided on the decorative layer. The lacquer layer 18 is intended, in particular, to prevent the decorative layer 14 from becoming soiled during filling of the grooves 11 with the metal paste 8.

(8) In the method for producing the decorative arrangement 4, the described decorative layer 14 is placed in the injection-compression molding tool 12. The side of the decorative layer 14 that faces away from view, that is provided with the lamination 16, is acted on by an injection pressure of a liquid plastic. This molds the desired decorative structure 10, including the grooves 11, into the decorative layer 14. Once the injected plastic cures, it forms a carrier layer 20 for the decorative arrangement 4. To have a desired 3D geometry, it is advantageous for the decorative layer 14 to be reshaped prior to the described first step. The injection-compression molding tool 12 should have a depth contour T.sub.WK that is greater than a desired depth contour T.sub.SWK of the grooves 11 of the decorative structure. This will ensure that overmolding occurs over the entire region of the decorative structure 10. This will be eliminated in a subsequent removal process in order to obtain the sharpest possible edges of the grooves 11. Thus, ensuring an accurate and precise view of the metal structure 8. For this purpose it is possible, but not necessary, for overmolded parts of the decorative layer 14 to be removed prior to the second step described in the next section.

(9) In the second step, as shown in FIG. 3, the grooves 11 of the decorative structure 10 are then filled with a metal paste 22. In a third step, the decorative layer 14 with the metal structure 8 is machined to a desired target dimension. In this case, it is by a grinding tool 24. If desired, the applied lacquer layer 18 can be removed to the greatest extent possible to allow the decorative layer 14 to be treated by grinding, pickling, and/or sealing after the removal of the overmolded parts. This influences the coloring of the decorative layer. At the same time, of course, the gloss level of the metal structure 8 can also be influenced.

(10) In the fourth and last step, as shown in FIG. 4, a protective layer 26, which in the present exemplary embodiment is a clear lacquer, is then applied to the decorative layer 14 with the metal structure 8.

(11) The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.
