Abstract
Disclosed is a molding having a translucent surface layer and to a method for producing a molding that has a translucent surface layer.
Claims19
1:
- A molding with a transilluminable surface layer at a visible side, comprising
- a functional film having at least one transilluminable region,
- a surface layer applied to the functional film on the visible side of the molding, wherein the surface layer is formed by a textile, leather, imitation leather, wood veneer or wood laminate or from a metal foil,
- a transilluminable layer injection-molded on the rear side of the functional layer and serving as a diffusing pane for incident light, wherein the rear side of the functional layer forms the side opposite the surface layer,
- and wherein lateral shielding of the transilluminable layer by bent-over regions of the functional film and the surface layer is realised, wherein a light barrier preventing lateral issue of light is provided by the thus-formed edge fold and wherein an optical conductor into which light can be introduced by way of a light source is arranged at the lower side of the transilluminable layer so that the transilluminable layer formed as a diffusing pane is illuminated over the whole area by way of the optical conductor for illumination of the at least one illuminatable region.

2:
- A molding with a transilluminable surface layer at a visible side, comprising
- a functional film having a reflective structure and at least one light source, wherein the reflective structure through laterally introduced radiation by the at least one light source produces irradiation at the visible side of the molding,
- the at least one light source is integrated in the functional film,
- a carrier layer of plastics material injection-molded on the rear side of the functional film, wherein the rear side of the functional film forms the side opposite the visible side of the molding,
- an at least regionally transilluminable surface layer disposed on the visible side of the molding, wherein the surface layer is formed by a textile, leather, imitation leather, wood veneer or wood laminate or from a metal foil,
- a transilluminable connecting layer arranged between the functional film and the surface layer and connected by a chemical connection and/or a mechanically positive connection with both the functional film and the surface layer,
- and wherein
- lateral shielding of the transilluminable connecting layer is realised by bent-over regions of the surface layer and
- the edge fold realised by the bent-over regions is held by a third plastics material which is injection-molded at the lower side of the functional film at the bent-over regions.

3:
- The molding according to claim 1, wherein the functional film comprises at least one functional element for operating and/or controlling at least one component connectible by way of signal connection with the functional film and the at least one functional element.
4:
- The method for producing a molding according to claim 1, with a transilluminable surface layer at a visible side, in a one-shot process without subsequent processes, comprising the following method steps:

- connecting the surface layer with the functional film,
- back-molding the functional film with a transilluminable plastics material in an injection-molding process, wherein the transilluminable plastics material is applied to the functional film and at least one side has an at least regionally smaller dimension than the functional film and
- bending over the projecting part of the functional film.
2 more elements
5:
- The method according to claim 4, wherein connecting the surface layer with the functional film is carried out prior to or after back-molding the functional film.
6:
- The method according to claim 4, wherein the surface layer completely covers the area of the functional film on the visible side.
7:
- The method of producing a molding according to claim 2, with a transilluminable surface layer at a visible side, in a multi-component injection-molding method in a one-shot process without subsequent processes, comprising the following method steps:
- inserting a functional film into a cavity of a mold half of an injection-molding tool, wherein the functional film has a reflective structure and at least one light source,
- back-molding the functional film in the injection-molding tool with a first plastics material for formation of a carrier layer for the functional film,
- transferring the first intermediate product formed from the functional film and the carrier layer into a second cavity of the injection-molding tool,
- introducing an at least regionally transilluminable surface layer into the second cavity, wherein the surface layer has a larger area dimension than the first intermediate product consisting of the functional film and carrier layer and wherein the surface layer is formed by a textile, leather, imitation leather, wood veneer or wood laminate or from a metal foil,
- injection-molding a second plastics material between the first intermediate product and the surface layer, wherein the second plastics material connects with the surface layer and the functional film,
- bending over projecting regions of the surface layer,
- transferring the second intermediate product consisting of the functional film, carrier layer, surface layer and second plastics material into a further cavity and
- over-molding the bent-over regions of the surface layer with a third plastics material at the rear side of the functional film, wherein the rear side is opposite the visible side of the molding.
