Description

 A decorative element consisting of at least one first layer and a second layer applied to the first layer is described. The decorative element also has an externally visible structure. Such decorative elements are increasingly used in motor vehicles. For example, dashboards in motor vehicles on decorative elements, which give a leather-like impression. Furthermore, decor elements are known from the prior art, which imitate a wooden surface.

For example, in order to impart a leather-like impression to a surface, in the prior art a film has hitherto been correspondingly embossed or a layer provided with a corresponding embossing.

These surfaces have a structure. The structure comprises depressions and elevations in which, in particular, dust and dirt can accumulate. Moreover, the visual appearance of these surfaces is limited to the formation of the structure as such.

It is therefore an object to provide a decorative element which protects a surface structure from contamination and immediately provides an attractive visual appearance while increasing the value of the surface.

The object is achieved by a decorative element with the technical features specified in claim 1. Advantageous developments are specified in the dependent claims in detail.

A decorative element which achieves the above object consists of at least a first layer and a second layer applied to the first layer. In this case, the first layer has a first structure on the side facing the second layer, and the second layer has a negative of the first structure on the side facing the first layer. The second layer is translucent and the first layer has a light hue, the first structure having at least a depth of 0.5 mm.

The translucent, translucent formation of the second layer allows the structure to show through behind the first layer, the first structure also being included in the second layer as a negative of the first structure. In order for the first structure to be visible with respect to the second layer, the first layer has a light hue. The light hue is to be determined depending on the light transmittance of the second layer, the layer thickness of the second layer and the depth of the first structure. A clear definition of the bright hue is not possible due to the lack of uniform normalizations. In particular, the light shade in other embodiments includes a white, beige or light gray hue. If, for example, a plastic with a certain translucency is applied as the second layer, the first structures appear in a certain thickness. If the light transmission of the second layer is changed, the show through of the structure or visible of the first structure can also be controlled. In addition, the layer thickness of the second layer is decisive for this.

The depth of the first structure is also crucial to the extent to which the first structure is visible from the outside. If first structures remain visible in a second layer with a lower light transmission, greater depths are required for the first structure. For example, a lower light transmittance of the second layer allows the first structure to disappear or disappear under a given light incidence. As a result, specific optical effects can be achieved in a targeted manner. Further, the layer thickness, texture depth, and light transmittance of the second layer as well as the hue of the first layer may be used to provide different designs for day and night, as the translucency of the first structure changes due to the different lighting conditions.

The application of the second layer to the first layer also ensures that no impurities, dust or dirt particles accumulate in the first structure. As a result, the appearance of the first structure is also retained since the elevations and depressions of the first structure are filled with the material of the second layer.

The first layer may have a second structure on the side facing away from the second layer. Depending on the layer thickness of the first layer and the depth of the second structure, this can achieve special optical effects. Depending on the viewing angle and the incidence of light, elevations and depressions of the second structure with respect to the second layer may be visible or not visible. The second structure, in particular, also realizes depth effects.

The first layer may have a third layer on the side facing away from the second layer. For example, the third layer may then comprise a negative of the second structure.

The second layer may have a smooth surface on the side facing away from the first layer. A smooth surface ensures that no impurities such as dust or dirt can be deposited.

In addition, the second layer may have an at least partially shiny or matt surface on the side facing away from the first layer. A glossy or matte surface of the first layer can be made depending on the material used for the second layer, with a glossy surface usually providing a glossy surface as well.

The first structure and / or the second structure in the first layer may comprise a symbol, a pattern, a relief or a negative of a symbol, an image or a pattern. In this case, regular or irregular repetitive depressions and surveys may be provided. A random arrangement of elevations and depressions can also form a first structure and / or a second structure. The first structure and / or the second structure can also have elevations and depressions which have a smaller height or depth than 0.5 mm. These elevations and depressions are therefore less visible and can be perceived, for example, only under certain light incidents.

On the side facing away from the second layer of the first layer and / or the third layer, a lighting device may be arranged and the first layer may be at least partially translucent. The illumination device makes it possible to represent the first structure and / or the second structure more clearly or, for example, to make the second structure visible only when illuminated. In one embodiment, the first structure is visible at normal incidence of light. When the illumination device is activated, the second structure becomes visible in the first layer and is visible through the first structure. Alternatively, the first structure and the second structure may be arranged at different positions. When the lighting device is activated, the second structure is additionally visible, for example. Depending on the light transmittance of the first layer, various optical effects can also be achieved in this case. For example, then the second structure can only be seen in an active lighting device with a view of the decorative element. So it is possible to create a 3D effect only with activation of the lighting device or to increase a 3D effect.

The first layer may be translucent in the region of the first structure and / or the second structure. The degree of transparency should be selected as a function of the depth of the structures, the layer thickness of the first layer and the desired optical effects.

A fourth layer may be arranged on the side of the first layer or the third layer facing away from the second layer, wherein the fourth layer has illumination means or the fourth layer is coupled to an illumination device which introduces light into the fourth layer.

The illumination device and the illumination means for both the fourth layer and for the first or third layer comprise conventional light sources such as light bulbs, halogen lamps, LEDs, etc. The illumination means and illumination devices may have special designs. For example, flat illuminants can span one or more areas completely or only in regions. Illuminants can be incorporated in further embodiments in one of the layers.

The fourth layer may have a third structure that deflects the light introduced into the fourth layer toward the first layer. For example, in the case of a flat decorative element, a lighting device can be arranged on one side and introduce light into the fourth layer. In this case, the fourth layer has a multiplicity of deflection structures which bring about a reflection of the introduced light. Preferably, the fourth layer may consist of a first sub-layer and a second sub-layer. The first sub-layer and the second sub-layer have different layer thicknesses at the opposite regions, so that the total layer thickness of the fourth layer remains essentially the same. In addition to the increase or decrease in the layer thicknesses of the first partial layer and the second partial layer, the third structure may run in the connecting regions between the first partial layer and the second partial layer. The third structure may consist of a plurality of elevations and depressions, which are formed in cross-section, for example. Triangular and whose axes which pass through the vertices of the triangles, extending parallel to the illumination device.

The first layer, the second layer, the third layer and / or the fourth layer may consist of a plastic.

In particular, the second layer can consist of polymethyl methacrylate, polyurethane, or polyurea or have these components. The second layer may be a colored transparent / translucent layer (eg, smoked glass) which is applied to the first layer in a 2-component injection molding process. In this case, the first layer is selected from a plastic, the one has bright hue. For example, the first plastic layer is formed substantially white.

The second structure and / or the third structure may have at least a depth of 0.5 mm. Decisive here is that components of the second and / or the third structure, which have a smaller depth, can be visible only under certain conditions. Therefore, it is not excluded that smaller depths are used for the second structure and / or the third structure.

The first structure and / or the second structure can be introduced into the first layer in such a way that a lithophane is produced with illumination via a lighting device or illumination means. In this case, the illumination can reverse an optical appearance of the first and / or the second structure. For example, the first structure in the unlit state shows a pattern with peaks and valleys, which cause a light-dark effect. After activation of the illumination device, the light-dark areas turn around and a different appearance can be provided.

The decorative element can, as already stated, for example, be used for dashboards in motor vehicles. Alternatively, decorative elements can also be used for other trim parts of a motor vehicle interior. However, the decorative element can also be used for other purposes and be provided for example on the surface of a piece of furniture.

Further advantages, features and design options will become apparent from the following description of the figures of non-limiting embodiments to be understood.
