    Abstract

    Implementations of the invention comprise a molded part, especially a decorative part and/or paneling part for a vehicle interior fashioned as a molded part, comprising a backing, especially a plastic backing, and a decorative layer, especially a wood veneer, wherein the decorative layer has a rear side facing the backing and a front side designed as a visible side, wherein at least one light source, especially a laser or a LED designed as the light source, is provided on or in the molded part. Implementations of the present invention also comprise a method for producing a molded part according to the invention.

    Claims

    1. A molded part, especially a decorative part and/or paneling part for a vehicle interior fashioned as a molded part, comprising: a backing, especially a plastic backing, and a decorative layer, especially a wood veneer, wherein: the decorative layer has a rear side facing the backing and a front side designed as a visible side, at least one light source, especially a laser or a LED designed as the light source, is provided on or in the molded part, one or more side lighting fibers connected to the light source are provided on the front side of the decorative layer, designed as the visible side, and the side lighting fiber or side lighting fibers run at least for a section in parallel with the front side of the decorative layer in one or more grooves provided in the front side of the decorative layer to accommodate the side lighting fiber or side lighting fibers.

    2. The molded part as claimed in claim 1, wherein: the at least one light source is provided at the rear side of the molded part or in a recess in the backing or at the side on the molded part, and the side lighting fiber or side lighting fibers are led backwards through the molded part or sideways out from the molded part at least at one of its respective ends for the connection with the light source.

    3. The molded part as claimed in claim 1, wherein: the side lighting fiber or side lighting fibers comprise polymer optical fibers and/or glass fibers, especially quartz glass fibers.

    4. The molded part as claimed in claim 1, wherein: the groove or the grooves extend into the decorative layer or entirely through the decorative layer, especially as far as the backing, preferably orthogonally to the front side of the decorative layer.

    5. The molded part as claimed in claim 1, wherein: the groove or the grooves are fashioned half-round or parabolic or rectangular in cross-section.

    6. The molded part as claimed in claim 1, wherein a transparent or translucent protective and/or optical layer is provided on the front side of the decorative layer, especially one made of PUR.

    7. The molded part as claimed in claim 1, wherein: the side lighting fiber or side lighting fibers are bonded and/or press-fitted into the groove or grooves.

    8. The molded part as claimed in claim 1, wherein: the side lighting fiber or side lighting fibers or a partial set of the side lighting fibers have a colored jacketing.

    9. A method for producing a molded part as claimed in claim 1, comprising the steps: providing of a material intended to form the decorative layer of the molded part, back injection of the material designed to form the decorative layer by means of injection molding with a backing material, especially a plastic, to form the backing, forming of at least one or more grooves on the front side of the decorative layer, inserting of one or more side lighting fibers into the groove or into the grooves.

    10. The method as claimed in claim 9, wherein: the side lighting fiber or side lighting fibers are introduced by bonding and/or press-fitting into the groove or grooves.

    11. The method as claimed in claim 9, wherein: a transparent or translucent protective and/or optical layer is provided, especially by depositing or casting, on the front side of the decorative layer, especially one made of PUR.

    12. The method as claimed in claim 9, wherein: the groove or grooves are milled on the front side of the decorative layer, or embossed, preferably by the top mold of an injection molding die.

    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

    [0027] FIG. 1 to FIG. 3 show a decorative part and/or paneling part for a vehicle interior fashioned as a molded part 10, comprising a plastic backing 12 and a wood veneer designed as the decorative layer 11. The decorative layer 11 has a rear side 13 facing the backing 12 and a front side 14 fashioned as the visible side. On the rear side of the molded part 10 there is provided a laser as the light source 15.

    [0028] There are three side lighting fibers 16 connected to the light source 15 provided on the front side 14 of the decorative layer 11 designed as the visible side. The side lighting fibers 16 run in sections in parallel with the front side 14 of the decorative layer 11 in three grooves 17 in the front side 14 of the decorative layer 11, designed to accommodate the side lighting fibers 16.

    [0029] The side lighting fibers 16 are led at one of their respective ends for connection to the light source 15 backward through the molded part 10, as can be seen in FIG. 2.

    [0030] The side lighting fibers 16 may be polymer optical fibers or glass fibers, especially quartz glass fibers. These are bonded or press-fitted in the grooves 17. The side lighting fibers 16 or some of the side lighting fibers 16 may have a colored jacketing.

    [0031] The grooves 17 extend orthogonally to the front side 14 of the decorative layer 11 in into the decorative layer 11 and are parabola-shaped in cross-section, as can be seen in FIG. 3. The grooves 17 are milled into the front side 14 of the decorative layer 11.

    [0032] FIG. 2 and FIG. 3 show that a transparent protective and/or optical layer 19 of polyurethane (PUR) is cast on the front side 14 of the decorative layer 11.
