Description

[0001] The invention relates to a molded part for a vehicle interior according to the preamble of claim 1.

[0002] Such molded parts comprise a decorative layer on a molded part front side designed as a visible side, a carrier, in particular a plastic carrier, on a rear side of the decorative layer, at least one light element arranged in and / or on the carrier for generating light and at least one light-guiding region for transmitting the light generated by the light element for backlighting at least part of the decorative layer, wherein the light-guiding region is formed by the carrier itself and / or is formed on a rear side of the carrier.The molded part comprises an opaque panel which forms a molded part rear wall on a side of the molded part opposite the visible side and forms one or more molded part side walls on side surfaces formed between the visible side and the molded part rear side, wherein the panel delimits the molded part in such a way that light generated by the light element does not exit from the rear or side of the molded part, wherein the panel is designed in several parts, wherein the panel comprises a main part for fully covering the rear of the molded part and one or more side parts for fully covering the side surfaces of the molded part.

[0003] In this context, “full-surface” means covering the entire surface or the entire area.

[0004] It is common practice to backlight the decorative layer of molded parts for vehicle interiors to create a particularly high-quality visual impression. For this purpose, lighting elements are installed behind the decorative layer, which backlight the decorative layer or shine through it. However, this often causes the problem that the light also radiates to the back and sides of the molded part or exits the molded part from the back or sides. This effect is undesirable and impairs the overall visual impression.

[0005] For the prior art, reference is made to DE 10 2006 011 849 A1, DE 20 2007 016 053 U1, DE 10 2011 016 417 A1, DE 10 2010 050 511 A1, DE 103 22 187 A1, EP 2 322 962 A1, WO 2007 / 045 338 A1, DE 40 06 649 C1, the generic EP 2 172 129 A2, DE 103 15 251 A1, DE 203 13 996 U1, DE 101 57 740 A1 and DE 41 37 135 C2.

[0006] It is therefore an object of the invention to provide a new molded part, in particular a molded part with a light element, in which an undirected radiation of the light is avoided.

[0007] This object is achieved by the features of claim 1. Advantageous embodiments and further developments are specified in the respective dependent claims.

[0008] The molded part according to the invention is characterized in that the side part(s) are Z-shaped.

[0009] The advantages of the invention lie in particular in the fact that this aperture effectively prevents undirected radiation of the light, whereby the optical quality of the molded part can be significantly increased.

[0010] A further development of the invention provides that the side part(s) and the main part are connected to one another at least in regions in a form-fitting and / or force-fitting and / or materially bonded manner, and / or the main part forms a projection on its end regions associated with the side part(s), wherein the projection preferably bears against at least two surfaces of the associated side part.

[0011] According to a further development, the side part(s) are at least partially molded onto the carrier, preferably on the side surfaces, or mounted on the carrier. Furthermore, it can be provided that the main part is at least partially molded onto the carrier and / or the side part(s) or mounted on the carrier and / or the side part(s), wherein the shape of the main part preferably corresponds substantially or at least partially to the shape of the carrier.

[0012] Preferably, the cover covers the side surfaces in such a way that the cover forms a positive fit with the front of the visible side in its end areas.

[0013] An advantageous and expedient development of the invention provides that the light element is or comprises a light source, wherein the light source is preferably or comprises at least one lamp and / or at least one illuminant and / or at least one LED and / or at least one luminous film, in particular an electroluminescent film.

[0014] One embodiment variant of the invention provides that a protective layer is provided on a front side of the decorative layer, wherein the protective layer comprises in particular a protective lacquer and / or a thermoplastic cover layer, preferably made of polymethyl methacrylate (PMMA), and / or a polyurethane (PUR) system, wherein the protective layer is preferably transparent and / or translucent and / or crystal clear.

[0015] It can be provided that the decorative layer is or comprises at least partially a natural material, in particular a wood veneer, and / or a plastic, in particular a film, and / or a textile material, in particular a fabric, and / or a metal. The decorative layer preferably has light openings and / or light guides for transmitting the light from the light-guiding region to the front side of the molded part and / or is at least partially translucent, in particular transparent and / or translucent and / or crystal-clear.

[0016] According to one embodiment of the invention, the panel has fastening elements for mounting the molded part in a vehicle interior. Alternatively or additionally, the carrier can have fastening elements for mounting the molded part in a vehicle interior, wherein the fastening elements extend through recesses in the panel, with light-shielding elements arranged on, in, or around the recesses.
