Description
Technical Field
[0001] The present application relates to a vehicle decorative part with a lighting function, and in particular to a vehicle interior decorative part with a lighting function. Background Art
[0002] Vehicle trims with lighting functions can be used to improve the overall aesthetic impression and visibility of operating and display elements of the vehicle. Typical vehicle trims of this type from the prior art include, for example, simple backlight panels or carriers with through holes corresponding to the backlight or backlight pattern. In order to additionally create an impression that is as aesthetically pleasing as possible and pleasant to the touch, the vehicle trim in this case usually includes a decorative, at least partially light-transmissive covering layer.
[0003] However, the solutions known from the prior art are not satisfactory, since the through-holes arranged behind the covering layer often create an uneven impression of the vehicle trim, at least in terms of feel. Summary of the invention
[0004] The object of the present invention is to provide an improved vehicle trim part, the improvement consisting in that the vehicle trim part provides a uniform tactile impression.
[0005] According to the invention, this object is achieved by a vehicle trim having the features of the independent claim. Possible embodiments and developments can be found in the dependent claims and in the following description.
[0006] The proposed vehicle decorative part with lighting function comprises a covering layer that is at least partially light-transmissive, a light-emitting lighting system for at least partially emitting light toward the covering layer, and a carrier arranged between the lighting system and the covering layer. The carrier comprises a plurality of recesses and a plurality of through holes, each of which is arranged on a surface of the carrier facing the covering layer and opens toward the covering layer, the recesses are closed toward the lighting system, and the through holes are open toward the lighting system.
[0007] The vehicle trim thus comprises a carrier which can be backlit by a lighting system, which means that a predetermined light pattern can be formed on the cover layer. Since the carrier comprises both through-holes which are open to the cover layer and the lighting system and recesses which are open only to the cover layer, a particularly uniform tactile impression of the vehicle trim is conveyed.
[0008] In the present context, light-transmissive is essentially intended to be understood as an optically transparent or translucent material, as opposed to non-translucent or opaque. In this context, light refers to visible light, i.e. light in the visible electromagnetic spectrum.
[0009] The vehicle trim may in particular be provided for a motor vehicle having an interior, for example for a passenger car. The vehicle trim may be a vehicle interior trim, for example as part of a door trim, a center console, a front console, a trunk trim or a roof trim.
[0010] The covering layer may be a translucent covering layer, i.e. it may be arranged to transmit the light emitted by the lighting system substantially diffusely. Alternatively, the covering layer may be transparent, i.e. it may be arranged to transmit the light emitted by the lighting system in a substantially directional manner. In the present case, the covering layer is a layer visible from the outside, such as a decorative layer, when the vehicle trim is used as intended. The intended use of the vehicle trim is understood to mean its use as part of the vehicle trim when installed in a vehicle. Therefore, when the vehicle trim is used as intended, for an observer, the carrier and the lighting system are arranged behind the covering layer.
[0011] The covering layer can be a substantially elastic covering layer. The covering layer can, for example, have an elastic modulus of 0.01 GPa to 0.5 GPa, in particular 0.2 GPa. In contrast, the carrier can be a substantially hard carrier. The carrier can, for example, have an elastic modulus of 0.5 GPa to 10 GPa, in particular 1 GPa to 2 GPa. The carrier can be a substantially dimensionally stable carrier that gives the vehicle trim its basic shape and stability. The covering layer can be arranged adjacent to (in particular directly adjacent to) the carrier. The covering layer can cover through-holes and recesses. When the vehicle trim is used as intended, the covering layer can at least partially (in particular completely) cover the surface of the vehicle trim visible from the outside. The covering layer can have depressions at least on the surface of the covering layer away from the carrier, which are arranged in the region of the through-holes and recesses. In other words, the covering layer can structurally reproduce and / or partially penetrate the contours of the through-holes and recesses (in particular the contours of the adjacent covering layer) at least in certain regions on the surface of the covering layer away from the carrier. The depth of the depressions measured substantially toward the through-holes and recesses may be at least 0.1 mm, and the minimum diameter measured orthogonally thereto may be at least 0.5 mm. In the case where the covering layer comprises recesses, the covering layer may also be a substantially hard covering layer, which is provided, for example, by deep drawing on a carrier or embossed according to the through-holes and recesses. When the vehicle trim is used as intended, the covering layer may be a layer of the vehicle trim that is directly contactable from the outside. The covering layer may be a substantially soft covering layer and have a compressive strength of 1 kPa to 50 kPa.
[0012] The carrier may be an at least partially reflective carrier. In this case, the carrier may at least partially have a reflective surface. The carrier may be arranged to reflect light emitted by the lighting system on its surface. The reflectivity of the carrier may be at least 40% or 60%. The reflectivity generally describes the ratio between incident radiation and reflected radiation. The carrier may at least partially comprise a reflective material. For example, the surface facing the through hole and / or the lighting system and / or the wall surface of the through hole may be reflective. For example, the surface of the carrier may be provided with a reflective film and / or another reflective coating. Alternatively, the carrier may at least partially consist of a reflective material. For example, the carrier may consist of a substantially white reflective material.
[0013] The carrier may be at least partially a substantially opaque carrier. It may be arranged to transmit substantially only light emitted by the lighting system which has passed through the through-hole to the cover layer.
[0014] The vehicle trim, the covering, the carrier and / or the lighting system may be substantially flat, i.e. have a base surface whose expansion in any direction is greater than the thickness of the corresponding component. In this case, the thickness of the covering is to be understood as its layer thickness. The covering, the carrier and / or the lighting system may extend substantially parallel to each other and / or complementary in their flat design. At least the carrier and / or the covering may be substantially flat or at least curved in the portion of its surface visible from the outside. The covering, the carrier and / or the lighting system may be substantially flat or at least curved in some portions.
[0015] The lighting system may be arranged to provide a substantially uniform backlighting of the carrier. Alternatively, the lighting system may be arranged to more intensely illuminate a predetermined area of the carrier, in particular an area in which the through hole is facing the lighting system and / or opening towards the cover layer. The lighting system may comprise at least one light source, such as an LED, a light panel or other illuminant. In addition, the lighting system may comprise at least one light guide, which is arranged to guide the light coupled in from the light source and to emit it at least partially towards the cover layer. In the light guide, the light may be guided along the device in a targeted manner, for example depending on the angle of incidence, and emitted in a scattered or non-scattered manner. The light guide may extend substantially parallel to the carrier and / or the cover layer. The light guide may, for example, comprise one or more laterally or radially emitting optical light guides, which extend, for example, substantially in a plane parallel to the cover layer and / or the carrier. As another example, the light guide may be designed as a panel, into which the light from the light source may be coupled from the side or, conversely, from the front.
[0016] According to one embodiment, the vehicle trim may also include a reflector, which is arranged behind the lighting system, in particular substantially behind the light guide of the lighting system, as viewed from the cover. Similar to the case of the reflective carrier, the reflector may at least partially include or consist of a reflective material, in particular on the surface of the reflector facing the cover and / or the carrier. The reflectivity of the reflector may be at least 40%, 60% or 80%. The reflector may be arranged to reflect the light emitted by the lighting system at least partially toward the cover and / or toward the carrier. The reflector may be a planar reflector and / or extend substantially in a plane parallel to the carrier, the cover and / or the lighting system, in particular to the light guide of the lighting system. The reflector may be arranged directly adjacent to the lighting system, in particular adjacent to the light guide of the lighting system. The reflector may be formed integrally with the carrier. The lighting system may be at least partially enclosed in a carrier integral with the reflector. The reflector may have a higher rigidity than the carrier, in particular a higher flexural strength.
[0017] In the region of the through hole, in particular in the region where the through hole opens toward the lighting system, an open space may be formed between the lighting system and the carrier and / or between the lighting system and the reflector, in which space the light emitted by the lighting system can propagate substantially unhindered. In other words, the carrier and / or the reflector may be spaced apart from the lighting system in this region.
[0018] The through holes and / or open spaces may be filled with a filler, in particular a transparent filler. The filler may be a polymer. The filler may have a strength greater than or equal to the strength of the carrier. Alternatively or in addition, the filler (in particular the filler filling the through holes) may have a refractive index>1. For example, the refractive index may be in the range between 1.4 and 1.6.
[0019] The through hole extends from the end opening toward the cover layer to the end opening toward the lighting system. The recess extends from the end opening toward the cover layer to the end closed toward the lighting system. In this case, the corresponding end can be formed by a step in the carrier. The through hole and the recess can extend all the way to the cover layer. The through hole and / or the recess can have a minimum diameter and a maximum diameter at least at the end opening toward the cover layer, as well as a minimum depth measured from the end opening toward the cover layer in the extension direction. The minimum diameter can be 0.5mm or 5mm, and the maximum diameter can be 10mm or 20mm. The minimum depth can be 0.1mm to 10mm, for example 0.3mm or 0.5mm. These dimensions can be selected so that the recess and / or the through hole are in principle tactilely and / or visually perceptible, and the visual perceptibility is intended to be particularly based on a distance of, for example, 30cm to 3m, which is common in the passenger compartment. The elasticity, light transmittance and / or thickness of the cover layer toward the carrier can be selected so that the recess and / or the through hole are tactilely and / or visually perceptible. Alternatively, the light transmittance and / or the thickness of the cover layer may be selected such that only the through-opening is visually perceptible and in particular only when the light-emitting lighting system is switched on.
[0020] The minimum distance between two through holes on the surface of the carrier facing the cover layer can be less than the thickness of the cover layer, in particular the layer thickness of the cover layer in the region of the through holes. At least some of the through holes can extend substantially parallel to each other or obliquely relative to each other in the extension direction.
[0021] The through holes may taper towards the cover layer. Alternatively, only some of the through holes may taper towards the cover layer. Other continuous or discontinuous shape gradients in the direction in which the through holes extend are also possible, depending on the desired light pattern on the cover layer.
[0022] At least on the surface of the carrier facing the cover layer, the through holes and recesses may be at least partially substantially uniform and / or of the same size. In this case, they may, for example, have a substantially circular, annular, triangular or square shape and / or have substantially the same diameter. The through holes and recesses may be arranged in a substantially regular pattern and / or be equidistant from adjacent through holes or adjacent recesses.
[0023] The carrier may comprise or consist of polypropylene (PP), a blend of polycarbonate / acrylonitrile butadiene styrene (PC ABS), polycarbonate (PC) and / or natural fiber reinforced polypropylene (NFPP). The covering layer may comprise or may be a film, leather and / or fabric. The covering layer may have a layer thickness of at least 0.5 mm, 1 mm or 5 mm. The vehicle trim may essentially have an absolute depth of 6 mm to 60 mm, or 10 mm to 40 mm, measured between the side of the covering layer facing away from the carrier and the side of the carrier or reflector facing away from the covering layer.
[0024] In the present case, several embodiments have been disclosed. Other embodiments of the present invention will become apparent to those skilled in the art through the following detailed description, which shows and describes yet another embodiment of the present invention by way of example. Therefore, the drawings and detailed description should be regarded as illustrative rather than restrictive. Recurring features are provided with the same reference numerals in the drawings. BRIEF DESCRIPTION OF THE DRAWINGS
[0025] In the attached picture:
[0026] Figure 1 is a schematic cross-sectional view of an embodiment of a vehicle trim according to the present invention;
[0027] Figure 2 yes Figure 1 A schematic plan view of an embodiment of wherein the lighting system is turned on; and
[0028] Figure 3 yes Figure 1 Schematic plan view of an embodiment in which the lighting system is turned off. DETAILED DESCRIPTION
[0029] Figures 1 to 3 A possible embodiment of a vehicle trim 10 with lighting function according to the present invention is shown. In the following, for both figures, recurring features are described only once.
[0030] The vehicle decoration part 10 with lighting function includes a cover layer 110 that is at least partially light-transmissive, a light-emitting lighting system 200 for at least partially emitting light toward the cover layer 110, and a carrier 120 arranged between the lighting system 200 and the cover layer 110. The carrier 120 includes a plurality of recesses 121 and a plurality of through holes 122, each of which is arranged on a surface of the carrier 120 facing the cover layer 110 and is open toward the cover layer, the recesses 121 are closed toward the lighting system 200, and the through holes 122 are open toward the lighting system 200.
[0031] The vehicle trim 10 thus comprises a carrier 120 which can be backlit by a lighting system 200, whereby a predetermined light pattern can be formed on the cover layer 110 depending on the arrangement of the through holes 122 and the recesses 121. Figure 2 , the lighting system 200 is turned on, i.e. the carrier 120 is illuminated from behind, and according to Figure 3, the lighting system 200 is turned off, i.e. the carrier 120 is not illuminated from behind. Since the carrier 120 comprises both a through hole 122 which is open towards the cover layer 110 and the lighting system 200, and a recess 121 which is open only towards the cover layer 110, a particularly uniform tactile impression of the vehicle trim 10 is conveyed. In addition, the recess 121 can contribute to a coordinated or more coordinated aesthetic impression of the vehicle trim 10. For example, depending on the design of the cover layer 110, in particular its layer thickness or light transmittance, and depending on the light conditions, in particular the light intensity of the luminous lighting system 200 and the ambient light independently thereof, the recess 121 can be visible on the cover layer 110 and thus complement the through hole 122 in a coordinated manner. In addition, since the recess 121 is provided in addition to the through hole 122, the weight of the vehicle trim 10 can be reduced. The proposed arrangement of only three main components is particularly easy to manufacture. For example, the carrier 120 may be formed together with the through-holes 122 and the recesses 121 in a single step, or these features may be drilled out of the carrier 120 later. Figure 2 and Figure 3 It can be seen that the vehicle trim 10 has a particularly coordinated design, for example, it is particularly easy to depict the Figure 2 The desired light pattern on the cover layer 110 in FIG.
[0032] The vehicle trim 10 may be provided in particular for a motor vehicle having an interior, such as for a passenger car. The vehicle trim 10 may be a vehicle interior trim, such as part of a door trim, a center console, a front console, a trunk trim or a roof trim.
[0033] The covering layer 110 can be translucent, i.e. it can be arranged to transmit the light emitted by the lighting system 200 in a substantially diffuse manner. The translucent covering layer 110 is particularly suitable for contributing to the coordinated impression of the vehicle trim 10, because, for example, the light emitted by the lighting system 200 can appear particularly soft. Alternatively, the covering layer 110 can be transparent, i.e. it can be arranged to transmit the light emitted by the lighting system 200 in a substantially directional manner. In the present case, when the vehicle trim 10 is used as intended, the covering layer 110 is a layer that can be seen from the outside, such as a decorative layer. Therefore, when the vehicle trim 10 is used as intended, for an observer, the carrier 120 and the lighting system 200 are arranged behind the covering layer 110.
[0034] The cover layer 110 can be substantially elastic. This can contribute to improving the tactile impression of the vehicle trim 10. The cover layer 110 can, for example, have an elastic modulus of 0.01 GPa to 0.5 GPa, in particular 0.2 GPa. In contrast, the carrier 120 can be substantially rigid. Therefore, the carrier 120 can be tactilely perceptible through the cover layer 110. The carrier 120 can, for example, have an elastic modulus of 0.5 GPa to 10 GPa, in particular 1 GPa to 2 GPa. The carrier 120 can be substantially dimensionally stable and provide the vehicle trim 10 with its basic shape and stability.
[0035] The cover layer 110 is arranged directly adjacent to the carrier 120. The cover layer 110 covers the through hole 122 and the recess 121. Figure 2 and Figure 3 It can be seen that when the vehicle trim 10 is used as intended, the covering layer 110 completely covers the surface of the vehicle trim 10 that is visible from the outside. In this case, when the vehicle trim 10 is used as intended, the covering layer 110 is a layer of the vehicle trim 10 that can be directly contacted from the outside. The combination of the elastic covering layer 110 covering the through-holes 122 and the recesses 121 and the hard carrier 120 (especially directly adjacent thereto) can provide a vehicle trim 10 that is particularly harmonious to the touch. In an alternative embodiment not shown in the drawings, the covering layer 110 may have recesses at least on the surface of the covering layer 110 that faces away from the carrier 120, which are arranged in the region of the through-holes 122 and the recesses 121. In other words, the covering layer 110 may structurally reproduce and / or partially penetrate the contours of the through-holes 122 and the recesses 121 (especially the contours of the adjacent covering layer 110) at least in certain areas on the surface of the covering layer 110 that faces away from the carrier 120. The depth of the depressions measured substantially towards the through-holes 122 and the recesses 121 may be at least 0.1 mm, and the smallest diameter measured orthogonally thereto may be at least 0.5 mm. In the case where the covering layer 110 comprises the depressions, the covering layer 110 may also be a substantially hard covering layer 110, which is provided, for example, by means of deep drawing on a carrier or is embossed according to the through-holes 122 and the recesses 121. By means of the depressions formed according to the through-holes 122 and the recesses 121, the covering layer 110 may contribute to a particularly coordinated tactile and / or aesthetic impression of the vehicle trim 10. The covering layer 110 may in principle be substantially soft and have a compressive strength of 1 kPa to 50 kPa, in order to further improve the tactile impression of the vehicle component 10.
[0036] exist Figure 1 , as an example, the light trajectory of the light emitted by the illumination system 200 is schematically indicated by a dashed arrow. By way of example, the carrier 120 shown is correspondingly at least partially reflective.
[0037] As a result, the light output provided at the cover layer 110 in the region of the through hole 122 can be increased, but the light emission angle can also be increased. In this case, the carrier 120 may at least partially have a reflective surface. The carrier 120 is arranged to reflect the light emitted by the lighting system 200 on its surface. The reflectivity of the carrier 120 may be at least 40% or 60%. The carrier 120 may at least partially include a reflective material. According to Figure 1 , at least the surface of the carrier facing the through hole 122 and the lighting system 200 is reflective, and the wall surface of the through hole 122 is also reflective. Figure 1 , the carrier 120 consists of a reflective material (eg a substantially white material). This variant is particularly easy to manufacture. Alternatively, the carrier 120 may be provided with a reflective film and / or another reflective coating on its surface.
[0038] In the present case, the carrier 120 is opaque and is designed to transmit only the light emitted by the illumination system 200 which has passed through the through hole 122 to the cover layer 110. Thus, for example Figure 2 As shown, the light pattern that may be provided on the cover layer 110 is substantially predetermined by the through holes 122 rather than by the recesses 121 .
[0039] according to Figures 1 to 3 The entire vehicle trim 10 and in particular the cover 110, the carrier 120 and the lighting system 200 are flat and substantially planar, the latter three components extending substantially parallel to one another and in a complementary manner to one another according to their flat design. Figure 1 The cross-sectional view in is orthogonal to the base surface of the vehicle trim 10. On the other hand, Figure 2 and Figure 3 1 is a plan view of the cover layer 110, at least schematically indicating the through-holes 122 and the recesses 121 arranged behind it. The carrier 120 and the cover layer 110 are flat on their externally visible surfaces. Alternatively, these components may also have curved and in particular parallel and / or complementary parts.
[0040] In the present case, the lighting system 200 is arranged to provide a substantially uniform backlighting of the carrier 120. Alternatively, the lighting system 200 may be arranged to more intensely illuminate predetermined areas of the carrier 120, in particular areas in which the through holes 122 open towards the lighting system 200 and / or towards the cover layer 110. For example, predetermined lighting effects and light patterns may be provided or intentionally manipulated. The lighting system 200 comprises at least one light source 210, such as an LED. Alternatively, the lighting system 200 may also comprise a light panel or other luminous body. Furthermore, the lighting system 200 comprises at least one light guide 220, which is arranged to guide the light coupled in from the light source 210 and to emit it at least partially towards the cover layer 110. By using the light guide 220, the lighting system 200 may generally be more flexibly and variably adapted to environmental conditions. The light guide 220 extends substantially parallel to the carrier 120 and the cover layer 110. According to the example shown here, the light guide 220 comprises at least one laterally or radially emitting optical light guide extending in a plane parallel to the cover layer 110 and the carrier 120. Figure 1 As another example, the light guide device 220 can be designed as a panel, and the light from the light source 210 can be coupled into the panel from the side or conversely from the front.
[0041] according to Figure 1, the vehicle trim 10 further comprises a reflector 130, which is arranged behind the lighting system 200, in particular behind the light guide 220, as viewed from the cover layer 110. Similar to the case of the reflective carrier 120, the reflector 130 may at least partially comprise or consist of a reflective material, in particular on the surface of the reflector 130 facing the cover layer 110 and / or the carrier 120. The reflectivity of the reflector 130 may be at least 40%, 60% or 80%. The reflector 130 is arranged to reflect the light emitted by the lighting system 200 at least partially towards the cover layer 110 and towards the carrier 120. As a result, the light output provided at the cover layer 110 in the region of the through hole 122 can be increased, and if necessary, the light emission angle can also be increased. The reflector 130 has a flat design and extends in a plane parallel to the carrier 120, the cover layer 110 and the lighting system 200, in particular to the light guide 220. In the present case, the reflector 130 is arranged at a distance from the lighting system 200. However, it can also be arranged directly adjacent to the lighting system 200, in particular adjacent to the light guide 220. The reflector 130 can be formed integrally with the carrier 110. In this case, the lighting system 200 can be at least partially enclosed in the carrier 120 that is integral with the reflector. This can increase the stability of the vehicle trim 10 and / or simplify its manufacture. The reflector 130 can have a higher rigidity than the carrier 120, in particular a high flexural strength. This can be particularly advantageous because the reflector 130 can thus compensate for the reduced stability of the carrier 120, which is provided with a plurality of through holes 122 and recesses 121.
[0042] like Figure 1 As shown, in the region of the through hole 122, in particular in the region where the through hole 122 opens toward the lighting system 200, an open space 140 is formed between the lighting system 200 and the carrier 120 and between the lighting system 200 and the reflector 130, in which space the light emitted by the lighting system 200 can propagate substantially unhindered. In other words, the carrier 120 and the reflector 130 may be spaced apart from the lighting system 200 in this region. This may also contribute to increasing the light output provided at the cover layer 110 in the region of the through hole 122, in particular in combination with the reflector 130 and / or the at least partially reflective carrier 120.
[0043] The through holes 122 and / or the open spaces 140 may be filled with a filler, in particular a transparent filler. The filler may be a polymer. The filler may have a strength greater than or equal to the strength of the carrier 120. This may also compensate for the reduced stability of the carrier 120, which is provided with a plurality of through holes 122 and recesses 121. Alternatively or in addition, the filler (in particular the filler filling the through holes 122) may have a refractive index>1. A refractive index>1 may increase the light emission angle at the through holes 122 toward the cover layer 110, which may contribute to a more uniform aesthetic impression of the vehicle trim 10. The refractive index of the filler may be in a range between 1.4 and 1.6. These values are particularly common values for transparent polymers.
[0044] The through hole 122 extends from the end opening toward the cover layer 110 to the end opening toward the lighting system 200. The recess 121 extends from the end opening toward the cover layer 110 to the end closed toward the lighting system 200. In this case, the corresponding ends are formed by steps in the carrier 120. The through hole 122 and the recess 121 extend all the way to the cover layer 110. The through hole 122 and / or the recess 121 may have a minimum diameter and a maximum diameter at least at the end opening toward the cover layer 110, and a minimum depth measured from the end opening toward the cover layer 110 in the extension direction. The minimum diameter may be 0.5 mm or 5 mm, and the maximum diameter may be 10 mm or 20 mm. The minimum depth may be 0.1 mm to 10 mm, for example 0.3 mm or 0.5 mm. In this case, these dimensions can be selected so that the recess 121 and / or the through hole 122 are in principle tactilely and / or visually perceptible, the visual perceptibility being intended to be based in particular on a distance of, for example, 30 cm to 3 m, which is common in the passenger compartment. The selection of appropriate dimensions can contribute to a coordinated or more coordinated tactile and / or aesthetic impression of the vehicle trim 10. In this case, the elasticity, light transmittance and / or thickness of the cover layer 110 toward the carrier 120 can be selected so that the recess and / or the through hole are tactilely and / or visually perceptible. Alternatively, the light transmittance and / or thickness of the cover layer 110 can be selected so that only the through hole 122 is visually perceptible, and specifically only when the light emitting lighting system 200 is turned on.
[0045] In each case, the minimum distance between two through holes 122 on the surface of the carrier 120 facing the cover layer 110 is smaller than the thickness of the cover layer 110, as in Figures 1 to 3. This may be particularly desirable in combination with a translucent cover layer 110, since this means that if there are two adjacent fully backlit through-holes 122, they can no longer be visually distinguished from each other on the cover layer 110, i.e. the luminous pattern appears more uniform. At least some of the through-holes 122 may extend in the extension direction substantially parallel to each other or obliquely with respect to each other. This enables, for example, visual effects to be produced depending on the viewing direction. According to Figure 1 , the two outer through holes 122 extend parallel to each other, while the middle through hole 122 extends at an angle relative to them.
[0046] The through holes 122 may taper toward the cover layer 110. Alternatively, only some of the through holes 122 may taper toward the cover layer 110. Figure 1 This is the case for the cross-sectional view shown for the through-hole 122 arranged on the outer right-hand side. By tapering the through-hole 122 accordingly, a higher light output and a larger light emission angle at the cover layer 110 can be achieved at said through-hole. However, other continuous or discontinuous shape gradients in the extension direction of the through-hole 122 are also possible, depending on the desired light pattern on the cover layer 110. As a result, optical effects (e.g. viewing angle-dependent effects) and light intensity gradients can be selectively influenced on the cover layer 110.
[0047] For example, in order to allow the most harmonious impression of the vehicle trim 10, the through holes 122 and the recesses 121 are uniform and of the same size at least on the surface of the carrier 120 facing the cover layer 110. In the present case, they have an annular shape with the same diameter. However, other shapes are of course possible. In addition, the through holes 122 and the recesses 121 are arranged in a regular pattern and are equidistant from adjacent through holes 122 or adjacent recesses 122.
[0048] The carrier 120 may include or consist of polypropylene (PP), a blend of polycarbonate / acrylonitrile butadiene styrene (PC ABS), polycarbonate (PC) and / or natural fiber-reinforced polypropylene (NFPP). These materials not only meet the requirements for the carrier 120, but they are also recyclable. The covering layer 110 may include or may be a film, leather and / or fabric. The covering layer 110 may have a layer thickness of at least 0.5 mm, 1 mm or 5 mm. The vehicle trim 10 may basically have an absolute depth of 6 mm to 60 mm, or 10 mm to 40 mm, which is measured between the side of the covering layer 110 facing away from the carrier 120 and the side of the carrier 120 or the reflector 130 facing away from the covering layer 110.
