Abstract

A molded part, in particular to an interior trim part of a motor vehicle, consists of a pressed carrier, formed from a fiber-plastic composite, a carrier structure made of a plastic for fixedly arranging the molded part on a motor vehicle, and a light source. The carrier structure is molded with an injection molding method to a surface of a rear side of the pressed carrier such that the carrier structure lies flat directly against the surface, in particular the entire surface, of the rear side of the pressed carrier. The pressed carrier is at least translucent, and the carrier structure is opaque. The carrier structure has at least one cutout, which forms a through opening to the surface of the pressed carrier. The light source is arranged for backlighting purposes on the rear side of the pressed carrier such that, with appropriate use, light is visible on a viewing side of the pressed carrier.

First claim

What is claimed is:

1. A molded part of a motor vehicle, comprising:
a pressed carrier formed from a fiber-plastic composite;
a carrier structure made of a plastic for fixedly arranging the molded part on the motor vehicle; and
a light source,
wherein the carrier structure is molded with an injection molding method to a surface of a rear side of the pressed carrier such that the carrier structure lies flat directly against the surface of the rear side of the pressed carrier,
wherein the pressed carrier is at least translucent, and the carrier structure is opaque,
wherein the carrier structure has at least one cutout, which forms a through opening to the surface of the pressed carrier,
wherein the light source is arranged for backlighting on the rear side of the pressed carrier such that, when providing backlighting, light is visible on a viewing side of the pressed carrier, and
wherein the fiber-plastic composite is formed via mixed fibers of natural fibers and plastic fibers.

2. The molded part according to claim 1 , wherein
the at least one cutout of the carrier structure is formed on the surface of the pressed carrier as a symbol or a character.

3. The molded part according to claim 2 , wherein
the carrier structure has a multiplicity of cutouts, and
wherein the cutouts on the surface of the pressed carrier form lettering or a graphic.

4. The molded part according to claim 1 , wherein
the carrier structure is a stiffening structure for the pressed carrier.

5. The molded part according to claim 1 , wherein
the pressed carrier comprises a translucent or transparent upper layer on a surface on the viewing side, and
an upper layer on the pressed carrier is a textile material, an imitation leather, a perforated leather, or a lacquer.

6. The molded part according to claim 2 , wherein
the carrier structure of the pressed carrier and the at least one cutout of the carrier structure are producible in a common production step of the injection molding method.

7. The molded part according to claim 2 , wherein
the pressed carrier is translucent in a manner such that the at least one cutout is visible from the viewing side of the pressed carrier in a state in which the light source provides backlighting for the pressed carrier and is not visible in a state in which the light source does not provide backlighting for the pressed carrier.

8. The molded part according to claim 1 , wherein
the plastic fibers comprise polyester fibers.

9. The molded part according to claim 1 , wherein the pressed carrier is transparent.

10. The molded part according to claim 1 , wherein
the carrier structure lies flat directly against the entire surface of the rear side of the pressed carrier.

11. The molded part according to claim 1 , wherein
the molded part is an interior trim part of the motor vehicle.
