Translucent decorative element and method for its production

The invention relates to a translucent decorative element and a method for producing the transilluminable decorative element and further an interior for a vehicle and a motor vehicle with the interior.

The so-called black panel technology is used in the vehicle sector for design elements. In most cases, additional lighting functions are integrated into the design elements whose structural elements should not be visible in a non-activated state. Instead, a black, often matte, surface is often desired. In an activated state of the light functions they should then in the otherwise uniform black area

emerge. The constructive elements associated with the light functions, which are usually integrated in the design element, should also be able to withstand strong light irradiation from the outside,

For example, in direct sunlight, not visible. This results in a particularly high-quality design element for a viewer.

The person skilled in various ways for producing such design elements are known. Conventionally, these are produced, for example, in a so-called in-mold labeling (I ML) process or in an in-mold decoration (IMD) process.

In the IMD process, a carrier foil with a motif to be transferred is placed inside a tool mold. The motif corresponds directly or as a negative image of a light function to be realized. For example, the motif may represent a viewing area of a control element of a vehicle to be produced, in which, for example, symbols such as arrows are recessed so that these areas can be backlit later and the light function can thus be realized. Often, the carrier film in one

Injection mold placed so that the subject faces the mold interior. If the plastic is then injected into the mold interior, the motif or the color pigments is transferred to the injection molded part. The film is not connected to the injection molded part. The motif coated injection molded part can then be taken out of the mold. In the IML process, a film is first printed with a motif and the film with the motif then placed in an injection mold. The motif points towards the inner wall of the tool. If the film is then back-injected with plastic, the film and the injection-molded part enter into a firm bond. The injection molded part is coated so to speak with the film. A visible side of the injection molded part is then decorated with the foil that carries the motif.

In such processes, it proves to be disadvantageous that the required shape tolerances and positional tolerances of the films used have to be compared to the surface to be decorated

Injection molded part can not be maintained if the design element to be produced reaches a size of 200 mm or more. The applied to the slides motifs that are transmitted to the realization of the light functions on the injection molded part, as a result, are not adequately positioned against the component edges. This results in a visually unfavorable

Appearance.

Another conventional way of producing the relevant design elements is to paint colored, for example, black colored translucent support parts on its back and partially remove the paint for producing the structure for the light function, for example with a laser again.

It proves to be disadvantageous that the wall thickness of the relevant carrier parts must be at least 3.5 mm, so that no surface defects such as sink marks occur. Due to the minimum required wall thickness and the associated distance between the paint layer and the surface of the design element, however, results in an undesirable depth effect. The light function is apparently about 3.5 mm deep inside the design element. However, this is not desirable in many cases.

The invention is based on the object, a generic transilluminable

To create decorative element which can be produced in almost any dimensions and in which an undesirable depth effect does not occur. The transilluminable decorative element should also be produced with little effort and high quality, with the latter on the

Lighting functions and the decorative element itself relates.

The object is solved by the subject matters of independent claims 1, 9, 11 and 12. The invention relates to a transilluminable decorative element, comprising at least one support member having at least partially lichttransmissiven properties on which at least partially an opaque colored layer is applied with at least one recessed area and at least one further layer with at least partially lichttransmissiven properties, at least partially on each support part and the opaque colored layer extending over the recessed area.

According to the invention, it is provided that means with optical diffusion properties and / or coloring properties are contained in the further layer and / or the carrier part.

With the help of the one or more recessed areas light functions can be realized by the recessed areas are backlit or illuminated.

The present invention offers the advantage that the recessed areas can be arranged very close below an environment-facing surface of the further layer. Thus, an undesirable depth effect can be advantageously avoided.

By the means with coloring properties, color properties of the further layer and the support part can be defined as desired. At the same time this is also a

Transmittance of the further layer and the support member influenced. By suitable coordination, the recessed areas in the opaque colored layer are advantageously not visible from the outside. Depending on the design requirements, the agents with coloring properties may be contained only in the further layer or only in the carrier part or in the further layer and the carrier part. This advantageously allows the decorative element to be adapted, for example, in terms of hue and color intensity.

Conveniently, the coloring properties of the agents may correspond to one color of the opaque colored layer to the at least one recessed area. The translucent decorative element thus receives a particularly uniform color properties and the recessed areas are particularly well hidden. In this way, for example, a black-panel effect can be realized if all colored parts are dyed black at least proportionally.

By the means with optical diffusion properties can be advantageously a

Matt effect and also achieve a particularly uniform hue. Hiding the recessed areas is thereby particularly effectively possible. The carrier part or the further layer or the carrier part and the further layer can be provided with means with optical Diffusion properties are provided. These agents may be purely exemplary color pigments on which light is also scattered. In this case, means with optical

Diffusion properties and coloring properties used. However, purely by way of example, in addition to color pigments with coloring properties, additional agents with optical diffusion properties can also be used. The latter can be, for example, a large number of finely divided small particles, on which light can be repeatedly broken and diffusely scattered.

Such and other agents having optical diffusion properties and coloring

Properties are known to the person skilled in the art.

Since the recessed areas can be produced directly on the carrier part in the present invention, without causing an undesirable depth effect, the transilluminable decorative elements according to the invention are advantageously produced in almost any size. The shape tolerances and position tolerances of the recessed areas, the latter in particular relative to outer contours of the decorative element, can be advantageously maintained. Since the recessed areas are located on one of the further layer facing side of the support member, the wall thickness of the support member in other

Directions increase almost arbitrarily. Surface defects as a result of

Manufacturing process, such as an injection molding process, advantageously not occur. The skilled person is of course aware that the increase in wall thickness is limited by superordinate boundary conditions. Such are purely exemplary

Requirements for a translucency of the support member, the realization of

Light functions is sufficient.

In a preferred embodiment of the present invention, it is provided that at least the carrier part contains agents with optical diffusion properties and coloring properties. This offers the advantage of having all the means necessary to produce one particular

uniform appearance may be needed, may be included in a single component. The recessed areas thus do not appear in a non-active state.

In a further preferred embodiment of the present invention, it is provided that at least the opaque colored layer is black and at least in the carrier part or the further layer containing agents with coloring properties are black. This offers the advantage that it is particularly easy and with high quality to have a black panel Effect is feasible. Black is basically also considered a color in the context of the present invention. When it is said in the context of the present invention that there are no agents with coloring properties, this implies that the elements in question are colorless.

In extensive experimental investigations, the following combinations, shown in Table 1, of the nature of the carrier part and of the further layer have proven to be particularly advantageous, since such a black panel effect can be realized particularly well. When used in the context of a black-panel effect of agents with coloring properties, these refer to the color black.

Table 1: Preferred combinations (X) of properties of the carrier part and the further layer

The combinations shown in Table 1 are suitable for a transilluminable

Decorative element with black panel effect with very high quality regarding the

Decorating element and the lighting functions. In principle, however, all other conceivable combinations are also suitable. By way of example, the combination of carrier part and further layer, not shown in Table 1, in which in each case only means with optical diffusion properties are contained, may be mentioned. With this combination, a black-panel effect can be realized, the black color properties are caused in this case only by the opaque black colored layer and the other layer and the support member or the means contained in these produce a particularly uniform hue of low intensity. By the strong

Diffusion effect, the recessed areas are invisible in a non-active state, even if an external light source illuminates the other layer.

In a further preferred embodiment of the present invention, it is provided that a layer thickness of the further layer is between 0.15 mm and 0.35 mm and / or one

Total thickness of the further layer and the opaque colored layer is between 0.2 mm and 0.6 mm and / or a layer thickness of the support member is at least 3 mm. This offers the advantage that a depth effect is particularly effectively avoided and a surface shape of the support member, or a region of the support member in which the opaque colored layer is applied, is particularly accurate. The term layer thickness refers to the further layer, the opaque colored layer and the support part, respectively, as a whole. The person skilled in the art will readily appreciate that the layer thicknesses of the further layer and / or of the carrier part may be subject to deviations in the recessed areas. However, those skilled in the art will readily appreciate how to design the elements concerned constructively, since the recessed areas are filled by the further layer and / or the carrier part. At this point, the layer thicknesses of the further layer and / or the carrier part may be slightly larger than mentioned above.

In a further preferred embodiment of the present invention, it is provided that a transmittance of the further layer is between 60% and 80%. This offers the advantage that on the one hand the recessed areas can be concealed particularly effectively and on the other hand the lighting functions can be realized in an active state with high quality.

In a further preferred embodiment of the present invention, it is provided that the transilluminable decorative element has an extension of 200 mm to 1000 mm. This offers the advantage that decor elements with a black panel effect are available in dimensions that could previously only be produced with disproportionately great effort.

In a further preferred embodiment of the present invention it is provided that a minimum distance from the recessed area limiting contours to each other between 0, 1 mm and 0.2 mm. This offers the advantage of having the recessed ones

Areas structural elements for the realization of lighting functions with very high resolution and high accuracy can be produced flexibly. In a further preferred embodiment of the present invention, it is provided that the carrier part consists at least partially of polycarbonate and / or the further layer at least partially consists of polyurethane or a thermoplastic elastomer. This offers the advantage that materials are used for the production of transilluminable decorative elements, which are particularly well processed, enable a variety of mechanical properties are favorable and are particularly well adapted in their optical properties.

Another aspect of the present invention relates to an interior trim for a vehicle comprising at least one transilluminable decorative element according to the invention. This offers the advantage that interior fittings with particularly high quality are particularly easy to produce and high-quality lighting functions in flexibly adaptable

May have characteristics.

In a preferred embodiment of the present invention it is provided that the

Interior equipment comprises at least one lamp, which is arranged at least partially opposite the recessed area behind and / or in the carrier part of the transilluminable decorative element. This offers the advantage that everyone has to

Realization of lighting functions required components are combined in a compact assembly. This can be easily and flexibly integrated, maintained and adjusted in a wide variety of vehicles. The arrangement of the bulb, the decorative element can be particularly simple and easy to see through. The light functions are so outstanding. Suitable lamps are combinations of light source, optical fiber and power supply into consideration. However, the term bulbs also includes variants in which not all of these elements are included. The term illuminant means technical means that are suitable by themselves or as a result of their integration into a technical environmental system to imitate light through the carrier part transilluminable in decorative elements in the direction of the recessed areas. Preferably, one or more LEDs, which are connectable to a device for power supply and control of a vehicle used.

Another aspect of the present invention relates to a motor vehicle comprising

at least one interior of the invention for a vehicle. This offers the advantage that the quality of the motor vehicle increases, the costs are reduced and the motor vehicle can be made more flexible. Advantageously, a day design and a night design for the motor vehicle can be realized with the interior. A further aspect of the present invention relates to a method for producing a transilluminable decorative element, in which a carrier part with at least partially

light transmissive properties is prepared and at least partially an opaque colored layer is applied to the support member which is recessed or removed in at least one area and at least one further layer is applied with at least partially light transmissive properties at least partially on each support member and the opaque colored layer, which runs over the recessed area. According to the invention, it is provided that in the production of the further layer and / or the carrier part, agents having optical diffusion properties and / or coloring properties are added.

Definitions of terms used apply to the method according to the invention as it were for the inventive illuminated element. With regard to the method, the opaque colored layer means to leave out in a region that this area is omitted from the outset during the production of the layer, or else this area in the

Afterwards, the layer is freed again.

The method according to the invention has the advantage that a method is available in which transilluminable decorative elements according to the invention can be produced particularly simply, flexibly and with high quality. Particularly preferred for the preparation of the support member and the further layer uhrformende methods are used. To produce the opaque colored layer, it is particularly preferable to use primary shaping or coating processes.

In a preferred embodiment of the present invention, it is provided that, at least in the production of the carrier part, agents with optical diffusion properties and coloring properties are added. This offers the advantage that in only one forming process step, a carrier part can be produced, which has all the characteristics for a particularly uniform appearance of a later transilluminable decorative element. Thus, purely by way of example, a wide range of different transilluminable

Produce decorative elements by the support member is always varied and the other layer is produced standardized in other downstream process steps.

In a further preferred embodiment of the present invention, it is provided that the recessed area is produced with a laser. This offers the advantage that the recessed areas can be produced with very high precision and very flexibly. With a Laser can produce a contour of a recessed area in compliance with shape and position tolerances with a resolution of less than 0.2 mm. With a laser, however, it is also possible to produce resolutions in significantly larger areas of, for example, several millimeters.

In a preferred embodiment of the present invention, it is provided that the carrier part is produced in an injection molding process and / or the opaque colored layer is painted or sprayed on and / or the further layer is produced in a foaming process. This offers the advantage that flexible and easy to carry out procedures are used, which are also very suitable for the production of large quantities. With regard to the foaming process, polyurethane foaming processes are particularly suitable. In this case, reactive liquid starting materials are metered, mixed and placed in a mold and react there to form a polyurethane foam.

Further preferred embodiments of the invention will become apparent from the remaining, mentioned in the dependent claims characteristics.

The various embodiments of the invention mentioned in this application are, unless otherwise stated in the individual case, advantageously combinable with each other.

Production of a transilluminable decorative element according to the invention in a further preferred embodiment.

FIG. 1 shows a schematic representation of a transilluminable decorative element according to the invention in a preferred embodiment. The transilluminable decorative element is shown here in sections in a cross-sectional view, so that its structural elements are visible. FIG. 1 shows a carrier part 10, an opaque colored layer 12, a recessed area 12 in the opaque colored layer 12 and another layer 16. The further layer 16 is applied to the opaque colored layer 12 and extends over the recessed area 14 , In the recessed area 14, the further layer is also applied to the carrier part 10. The carrier part 10 and the further layer 16 have partially lichttransmissive properties. The light transmissive properties of the further layer 16 are so pronounced that it has a clear appearance. The carrier part 10 contains agents with coloring properties 18 as well as agents with optical diffusion properties 20. The agents with coloring properties 18 are black pigments. The means with optical

Diffusion Properties 20 are small particles that diffuse light diffusely. It is also possible to use black pigments on which even light is diffusely scattered. The carrier part 10 therefore has a matt black appearance. The opaque colored layer 12 is completely light-tight and also matte black. The transilluminable decorative element therefore has an overall matt-black appearance as viewed from an outer visible side 22. The recessed area 14 is not visible in the opaque colored layer 12 against the background of the support part 10. The recessed area 14 is designed to appear as light functions when the transilluminable decorative element is transilluminated from a lighting side 24. The recessed area 14 is part of a complex symbolism that can be displayed as light functions. The carrier part 10 is made of polycarbonate and has a layer thickness which does not fall below 3.5 mm at any point. The further layer 16 is made of polyurethane and has a layer thickness of 0.25 mm. The opaque colored layer 12 is a black lacquer layer and together with the further layer 16 has a total thickness of 0.5 mm. The transilluminable decorative element has an extension up to 1000 mm. The recessed area 14 or the complex symbolism extends in different areas for the realization of locally distributed light functions, wherein individual recessed areas extend up to 150 mm, wherein limiting contours 26 have a minimum distance of 0.2 mm and less. Shape and positional accuracy of the complex realized with the recessed areas

Symbols have deviations of not more than 0, 1 mm, but not more than 0.2 mm. When the transilluminable decorative element is transilluminated, the light functions in the form of the complex symbolism emerge over the recessed areas in apparently precise form and accurate alignment relative to outer contours of the transilluminated decorative element. A corner radius of the support member 28 is 0.5 mm. This avoids that form 12 areas with different paint thickness when painting the opaque colored layer. Thus, a wavy surface, which would be detrimental to the visual appearance, prevented. A corner radius of the further layer 30 is 1 mm. This advantageously avoids that the layer thickness increases in the corner region and a depth effect occurs.

Figure 2 shows a schematic representation of an inventive interior trim for a vehicle in a preferred embodiment. If the same reference numerals are used as in FIG. 1, they describe the same features. Unless otherwise stated, the features described for FIG. 1 then apply to these features. The interior decoration in FIG. 2 is shown in a cross-sectional view. The interior includes a

Inventive transilluminable decorative element 32. The interior is purely exemplary of an interior trim for a motor vehicle with an ambient light, with a day design and a night design can be generated. The interior equipment further comprises a lighting means 34. The lighting means 34 is arranged substantially opposite a plurality of recessed areas 14 behind the carrier part 10. The luminous means 34 comprises a light guide, which is designed to emit light into the carrier part 10 in the direction of the recessed regions 14. Furthermore, the interior trim comprises further structural elements for partitioning off and fastening 36. To seal off the transilluminable decorative element 32 and the luminous means 34, for example, a chrome clasp may be provided. For attachment of the interior of various structural elements can be provided, which are known in principle to those skilled in the art. As a difference from the variant shown in FIG. 1, in this exemplary embodiment the carrier part 10 has only means with optical diffusion properties 20 and the further layer 16 contains means with coloring properties 18. The means 16 with coloring properties 18 have the further layer 16 a black appearance on. By the means with coloring Properties 18, a transmittance of the further layer 16 is reduced to 70%. When viewed from a visible side 22, the transilluminable decorative element 32 therefore has a clear black-colored appearance. The recessed areas 14 are not visible even with intensive light irradiation from the visible side 22 forth. Since the layer thickness of the further layer 16 is only 0.25 mm, a depth effect does not occur. If light is emitted from the illumination side 24 with the luminous means 34 through the carrier part 10 in the direction of the recessed regions 14, this is diffusely scattered in the carrier part 10 and causes the light function on the recessed regions 14 to be visible from the visible side 22 , Due to the diffuse scattering, the light function appears particularly even. The result is a high-quality black panel effect.

FIG. 3 shows a schematic representation of a transilluminable decorative element according to the invention in a further preferred embodiment. If the same

Reference numerals as used in Figure 1, these describe the same features. Unless otherwise stated, the features described for FIG. 1 then apply to these features. The transilluminable decorative element in this embodiment differs from the embodiment described in Figure 1, especially in that the opaque colored layer 12 is not a lacquer layer, but an injection molded part, which is molded onto the support member 10. The recessed area 14 is completely filled in here by the carrier part 10. In other words, the recessed area 14 in the opaque colored layer 12 formed as an injection molded part is realized by injecting the opaque colored layer 12 around the area of the support part 10 which is to fill the recessed area 14. Thus, in this exemplary embodiment of the transilluminable decorative element, an injection-molded part that consists of several components is involved. The further layer 16 is, as with others

Embodiments may also be the case, at least partially made of polyurethane or a thermoplastic elastomer, at least partially applied to the support member 10 and the opaque colored layer 12 cohesively. Clearly recognizable are the means distributed in the carrier part 10 with optical diffusion properties 20. The further layer 16 contains in this embodiment means with coloring properties 18 and is colored black with a clear appearance. The transmittance of the further layer 16 is thereby 70%. The layer thickness of the further layer 16 is 0.4 mm. The distance from the recessed region 14 delimiting contours 26 is at a boundary to the other layer 16 1 mm. FIG. 4 shows a schematic representation of a motor vehicle according to the invention in a preferred embodiment. The upper part of Figure 4 shows the motor vehicle 38 in a front view. The middle part of Figure 4 shows the motor vehicle 38 in a rear view. The lower part of Figure 4 shows the motor vehicle 38 in a side view. The motor vehicle 38 has at several installation positions an inventive interior equipment for a vehicle 40, which each contain at least one inventive transilluminable decorative element 32. The interiors can have different characteristics and be provided in different mounting positions. By way of example only and not by way of limitation here are an instrument panel 42 in the area of a cockpit of the

Motor vehicle 38, switching and controls 44 such as in the field of

Vehicle doors or in the area of a center console, purely by way of example on a gear lever of a gearshift called and illuminated decorative elements with day and night design 46 in various areas of the motor vehicle 38. Particularly preferred

Interior fittings used with black panel effect.

FIG. 5 shows a schematic representation of a method according to the invention for

Production of a transilluminable decorative element according to the invention in a preferred embodiment. In a first method step, first a carrier part 10 having at least partly light-transmissive properties is produced. Preferably, the carrier part 10 is produced in an injection molding process. The support member 10 is preferably at least partially made of polycarbonate. The material from which the support member 10 is made, agents having optical diffusion properties 20 and / or agents with coloring properties 18 are added. Preferably, the colorant-providing agents 18 have a black visual appearance. Preferably, a corner radius of the support member 28 is 0.5 mm. Depending on the angle over which the radius is carried out in the region of the corner, other radii may be expedient, as long as the carrier part 10 has a paintable radius in the region of the corner. As radii that can be painted, such radii are used, in the area of which, in the case of later painting, there are no areas with different radii

Form coating thicknesses. In a second method step, substantially opposite a region which will later become a recessed region 14

Masking 48 applied in sections on the support member 10. In a third

Process step is an opaque colored layer 12 at least

applied in sections on the support member 10, preferably painted. Around

Masking 48 thus results in a recess 50 in the opaque colored layer 12. Preferably, the opaque colored layer 12 is black. In a fourth method step, the masking 48 is removed and substantially opposite to Area, from which the masking 48 has been removed, made with a laser 52, a recessed area 14 in the opaque colored layer 12. In a fifth method step, a further layer 16 with at least partially light-transmissive properties is applied at least partially on the carrier part 10 and the opaque colored layer 12 in a foaming process. This process step can be carried out both under pressurization, wherein a reaction mixture for the further layer 16 is injected into a tool, as well as without pressurization by

Pour over the corresponding areas of the support part 10 and the opaque colored layer 12 with the reaction mixture. The further layer 16 is formed over the recessed area 14 away. In this case, agents having optical diffusion properties 20 and / or agents having coloring properties 18 are added to the reaction mixture from which the further layer 16 is produced. If such agents have also been added to the material for the carrier part 10 in method step one, this is optional in method step five. Preferably, the colorant-providing agents 18 have a black visual appearance. The means 18, 20 can be adjusted in the carrier part 10 and / or the further layer 16 in such a way that a black panel effect with a variety of design graduations can be realized with the producible translucent decorative elements 32. The detail view shows properties that are preferably produced in the process. For example, a layer thickness of the further layer 16 is preferably produced between 0.15 mm and 0.35 mm. A total thickness of the further layer 16 and the opaque colored layer 12 is preferably made between 0.2 mm and 0.6 mm. The layer thickness of the carrier part 10 is preferably at least 3 mm. The corner radii of the carrier part 28 and the further layer 30 are preferably 0.5 and 1 mm. In principle, the person skilled in the art can adapt the method in accordance with the design requirements, wherein a decreasing layer thickness of the further layer 16 advantageously reduces a depth effect, but must not become so small that the design requirements regarding color tone and transmittance are missed. The layer thickness of the support member 10 is limited downwards by the requirements of a dimensionally accurate surface and upwards, as well as the other layer 16 by design requirements. Overall, the further layer 16 and the support member 10, whose optical properties interact, must be coordinated so that a high-quality black panel effect remains possible and a depth effect is avoided.

FIG. 6 shows a schematic representation of a method according to the invention for

Production of a transilluminable decorative element according to the invention in a further preferred embodiment. In a first method step, first as in FIG. 5 a support member 10 made in an injection molding process. The present variant of the method differs from the method variant of FIG. 5 in that, in a second method step, the light-impermeable colored layer is then injected onto the carrier part 10 as a further structural part 54. Subsequently, in a third method step, as also in FIG. 5, the further layer 16 is applied to the carrier part 10 and the further structural part 54.
