Description

The invention relates to a molded part, in particular a decorative part (also: ornamental part) and/or trim part designed as a molded part for a vehicle interior.

Numerous decorative and trim parts are installed in the vehicle interior, such as door panels, console and instrument panels. The decorative and trim parts also include control buttons and their covers.

Out of DE 20 2016 104 031 U1 are molded parts with rear light elements that backlight translucent recesses in a decorative layer and thus make the lines formed by the recesses visible to a viewer even at night.

Out of DE 10 2021 200 379 A1 A vehicle interior trim part comprising a decorative layer with through-openings that form a light path is known.

Out of DE 20 2019 005 317 U1 An illuminable decorative part with a decorative layer that is at least partially translucent is known.

Out of EP 2686 203 B1 A lighting device for a motor vehicle with a first plate illuminated from an underside is known, wherein the first plate has a plurality of transparent and non-transparent elements, each of which extends completely from the underside to the top of the first plate.

The requirements for such molded parts are constantly increasing; in particular, there is a need for molded parts with which a variety of optical lighting effects can be realized on the visible side.

The invention is based on the object of specifying a new molded part, in particular a molded part which has a changeable light design.

This object is achieved by a molded part having the features of claim 1 and by a molded part having the features of claim 3. Advantageous embodiments and further developments are specified in the respective dependent claims.

The molded part according to the invention comprises a decorative layer with a front side designed as a visible side and a back side opposite the front side. The decorative layer is opaque to light striking the back of the decorative layer, except for translucent recesses in the decorative layer. The molded part also comprises at least one light element that emits light onto the back of the decorative layer to illuminate the translucent recesses in the decorative layer. Translucent recesses are understood to mean, in particular, light passages in an opaque environment that enable the light striking the back of the decorative layer to be passed on to the front of the decorative layer. For this purpose, the translucent recesses do not necessarily have to extend through the entire decorative layer; rather, it is sufficient if the translucent recesses extend through an opaque area of the decorative layer and the light can travel the rest of the way through the decorative layer through transparent or translucent areas of the decorative layer. In particular, a longitudinal axis of the respective translucent recess can extend perpendicular to the back of the decorative layer.

The invention provides that the translucent recesses comprise at least one first translucent recess and at least one second translucent recess. The translucent recesses can be, for example, recesses that are visible to an observer. However, they can also be, for example, a microperforation, with a perforation being placed under a microperforation that is not visible to an observer in a non-backlit state, i.e. cannot be distinguished or can hardly be distinguished from a non-microperforated area.

The at least one first translucent recess is filled with a first color and/or covered on the back of the decorative layer with a first color layer formed by the first color, so that the at least one first translucent recess forms a first color filter for light incident on the back of the decorative layer.

The at least one second translucent recess is filled with a second color and/or covered on the back of the decorative layer with a second color layer formed by the second color, so that the at least one second translucent recess forms a second color filter for light striking the back of the decorative layer. The first color and the second color are two different colors. The first color filter and the second color filter differ accordingly in terms of the wavelength spectrum they block or allow to pass through and thus in terms of their light transmission for incident light.

The light element is a two- or multi-spectral light element that can emit at least a first light color and at least a second light color, wherein the wavelength spectrum of the first light color differs from the wavelength spectrum of the second light color. A light color is defined in particular by its wavelength spectrum, i.e. by the spectral composition of the light. The wavelength spectrum can be composed, for example, of discrete individual spectral colors of a specific wavelength and/or of a light mixture of several wavelengths or wavelength ranges and/or of a continuous spectral range. In particular, the intensity distribution across the wavelengths of the spectrum is characteristic of the respective light color. The light color can be changed by filtering. Filtering can be done using a color filter, wherein a color filter, for example, selectively absorbs or transmits certain colors from the wavelength spectrum of the light, i.e. a color filter can change the color spectrum of the light and thus the light color.

Furthermore, according to the invention, it is provided that the light transmission of the first color filter for the first light color is greater than for the second light color and the light transmission of the second color filter for the second light color is greater than for the first light color. It can also be provided that the light transmissions of the first color filter and the second color filter also differ from one another for other light colors.

Furthermore, the invention provides

(Aspect 1) that the at least one first recess forms a first symbol and/or decoration and the at least one second recess forms a second symbol and/or decoration, wherein when the first light color is emitted by the light element, the first symbol and/or decoration is visible on the front side of the decorative layer, in particular primarily or exclusively the first symbol and/or decoration is visible on the front side of the decorative layer, wherein when the second light color is emitted by the light element, the second symbol and/or decoration is visible on the front side of the decorative layer, in particular primarily or exclusively the second symbol is visible on the front side of the decorative layer, and wherein the light element can emit at least a third light color, wherein the wavelength spectrum of the third light color differs from the wavelength spectrum of the first light color and the second light color, wherein when the third light color is emitted by the light element, the first symbol and/or decoration as well as the second symbol and/or decoration are visible on the front side of the decorative layer,
and/or

(Aspect 2) that the translucent recesses additionally comprise at least one third translucent recess, wherein the at least one third translucent recess is filled with a mixture or layering of the first color and the second color and/or is covered on the back of the decorative layer by a color layer formed by the first color and the second color or by two color layers layered on top of each other, wherein one of the two color layers is formed by the first color and another of the two color layers is formed by the second color, so that the at least one third translucent recess forms a third color filter for light incident on the back of the decorative layer.

A further development of the aforementioned aspect 2 provides that the at least one first recess forms a first symbol and/or decoration and the at least one second recess forms a second symbol and/or decoration, wherein when the first light color is emitted by the light element, the first symbol and/or decoration is visible on the front side of the decorative layer, and wherein when the second light color is emitted by the light element, the second symbol and/or decoration is visible on the front side of the decorative layer.

An embodiment of the aforementioned further development provides that the light element can emit at least a third light color, wherein the wavelength spectrum of the third light color differs from the wavelength spectrum of the first light color and the second light color, wherein when the third light color is emitted by the light element, the first symbol and/or decoration as well as the second symbol and/or decoration are visible on the front side of the decorative layer.

The visibility of a symbol and/or decoration is understood in particular to mean that a symbol and/or decoration formed by the shape of this recess or these recesses is recognizable to an observer by means of one or more illuminated recesses, in particular in a plan view of the front side of the decorative layer.

The symbol may, for example, be one or more functional symbols and/or geometries and/or shapes and/or one or more letters and/or lettering and/or characters and/or logos and, in the case of decorations, may, for example, be lines, in particular form-following lines, and/or other design elements and/or patterns and/or designs which are on the visible side of the decorative layer of the molded part.

In particular, the first color filter of the at least one first translucent recess primarily lets the first light color through, whereas the second light color is significantly weaker or not visible at all through the first color filter, and the second color filter of the at least one second translucent recess primarily lets the second light color through, whereas the first light color is significantly weaker or not visible at all through the second color filter. When the first light color is irradiated, the at least one first recess is therefore primarily or exclusively visible in the first light color, i.e. the at least one first recess shines in the first light color. When the second light color is irradiated, on the other hand, the at least one second recess is primarily or exclusively visible in the second light color, i.e. the at least one second recess shines in the second light color.

The colour layers can, for example, be coloured printing layers, such as screen printing layers, and/or coloured lacquer layers and/or coloured foils.

The two- or multi-spectral light element can be a light element with an adjustable wavelength spectrum that is emitted by the light element, i.e. a light element with a changeable light color. RGB LEDs, for example, can be considered as a light source for the light emitted by the light element. These are composed of diodes for the primary colors red, green and blue and can shine in different light colors that can be selected depending on how the red, green and blue diodes are controlled. For example, it can be provided that white light can also be emitted by the light element.

The light element can be arranged on the back of the decorative layer. The light element can, for example, be a flat light element.

The light element itself can comprise one or more light sources. For example, these light sources can be arranged on the back of the decorative layer. The light element can also be a light guide, in particular a flat one, or comprise one. The light from a light source arranged elsewhere, for example RGB LEDs, is radiated into this light guide. For example, the light guide, in particular a flat one, can extend on the back of the decorative layer and the light is radiated laterally into the light guide. The light sources, for example RGB LEDs, can thus be arranged laterally on this light guide, radiate the light laterally into the light guide and the light guide then radiates the light onto the back of the decorative layer to illuminate the light-permeable recesses in the decorative layer. The light guide can be a light-conducting layer of the molded part, for example a transparent or translucent carrier on the back of the decorative layer.

The advantages of the invention lie in particular in the fact that two or more different symbols and/or decorations can be displayed on the visible side of the molded part, either individually or together, simply by changing the light color of the light element. Depending on the light color, symbols and/or decorations can thus be shown or hidden, for example. For example, a red first light color can display symbols and/or decorations that are formed by first translucent recesses that are filled with red color or covered with a red layer of color. In contrast, the red first light color hides symbols and/or decorations that are formed by second translucent recesses that are filled with blue color or covered with a blue layer of color, for example. With a blue second light color, on the other hand, the symbols and/or decorations that are formed by the second translucent recesses that are filled with blue color or covered with a blue layer of color are displayed. In contrast, the blue second light color hides symbols and/or decorations that are formed by the first translucent recesses that are filled with red color or covered with a red layer of color. With light mixtures or other light colors, both of the aforementioned variants of symbols and/or decorations can be shown in different light intensities and/or color tones. By varying the light color generated by the light element accordingly, changing designs can be realized on the front of the decorative layer. The molded part has a changeable light design.

Thus, the invention makes it possible to change the symbols and/or decorations displayed on the visible side of the molded part by changing the light color of the light element. For example, parameterized designs can also be used to implement ambient display elements with, for example, a warning function.

Another advantage of the molded part is that it has a no-show effect, i.e. the symbols and/or decorations are visible when the light element is switched off. not or at least almost not recognizable. On the other hand, when the light element is switched on, the symbols and/or decorations are usually at least partially recognizable to an observer on the front of the decorative layer, depending on the light color set.

One embodiment of the invention provides that the color of the respective recess, i.e. the fill color or the color of the color layer covering the recess, is only visible to a viewer if the light color emitted by the light element corresponds to this color or at least has wavelength components that are allowed through by this color, so that the color allows light transmission for these wavelength components. The first and second colors can be complementary colors. Accordingly, the color and complementary color of the respective recesses and thus the patterns possibly formed by the respective recesses are only visible when the corresponding color or complementary color is irradiated.

One embodiment provides that the light element can be switched at least between a first state in which it emits the first light color and a second state in which it emits the second light color. In addition, one embodiment of the invention can provide that a mixed color is also possible, i.e. the emission of a mixed light color from the first and second light colors by the light element. Additional light colors and mixtures of the different light colors can also be set. For example, it can also be provided that the light element emits white light.

According to a further development, the first color and the second light color are coordinated with one another such that the light transmission of the second light color through the first color filter is at least almost zero. Alternatively or additionally, it can be provided that the second color and the first light color are coordinated with one another such that the light transmission of the first light color through the second color filter is at least almost zero. If both measures are implemented, it is achieved that when the first light color is emitted by the light element, light at least essentially only passes through the first translucent recesses and when the second light color is emitted by the light element, light at least essentially only passes through the second translucent recesses.

One embodiment provides that when the first light color is emitted by the light element, the second symbol and/or decoration on the front side of the decorative layer is not visible or at least almost not visible or at least significantly less visible than the first symbol and/or decoration. It is further provided that when the second light color is emitted by the light element, the first symbol and/or decoration on the front side of the decorative layer is not visible or at least almost not visible or at least significantly less visible than the second symbol and/or decoration.

According to a further development, the light transmission of the first light color and the second light color through the third color filter is at least almost zero.

One embodiment of the invention provides that the first and second colors are complementary colors, in particular complementary colors according to the so-called Itten color wheel. Alternatively or additionally, it can be provided that the first and second light colors are complementary colors, in particular complementary colors according to the so-called Itten color wheel.

The first color and the first light color can have at least substantially the same hue. Alternatively or additionally, the second color and the second light color can have at least substantially the same hue.

The decorative layer can have a single material layer that is opaque except for the recesses. However, it is also possible for the decorative layer to be made up of two or more layers and to comprise a transparent or translucent decorative layer on its front side and an opaque layer on its back side, with the translucent recesses being formed in the opaque layer. The light radiated from the back side can pass through these recesses and then spread further to the front of the decorative layer due to the transparent or translucent design of the further layer or layers.

The transparent or translucent decorative layer is in particular a continuous decorative layer, i.e. the decorative layer has no recesses and/or openings and/or light passages.

The opaque layer can comprise or be adhesive, in particular colored adhesive, and/or fleece, in particular light-blocking fleece, and/or a film, in particular an ABS film or a PC film or a PMMA film.

The decorative layer and the opaque layer can be directly adjacent to each other. However, it is also possible that there is a gap between the decorative layer and the opaque layer. impermeable layer a transparent or translucent stabilizing layer is arranged. Alternatively or additionally, one or more transparent or translucent adhesive layers and/or other transparent or translucent intermediate layers can also be provided.

The decorative layer and/or the decorative ply is or comprises, for example, a wood veneer and/or a metal layer and/or a plastic and/or a film and/or a textile layer and/or a fabric and/or carbon and/or a stone layer and/or a slate layer and/or a marble layer.

Furthermore, the molded part can have a carrier on which the decorative layer is arranged with its rear side, optionally with the interposition of the color layer or layers. The light element can be arranged on a rear side of the carrier opposite the decorative layer, the carrier being transparent or translucent so that the light can reach the rear side of the decorative layer. Alternatively or additionally, the light element can be arranged in the carrier, for example in a recess in the carrier. In this case too, the carrier is transparent or translucent.

The carrier can be a plastic carrier and can be, for example, injected, cast or glued onto the color layer(s) and/or the back of the decorative layer.

The light element itself can comprise one or more light sources, for example RGB LEDs. It can be provided that the light element is or comprises a light-conducting layer of the molded part, with light being radiated laterally into this light-conducting layer, and with this light-conducting layer radiating the light radiated laterally at least partially onto the back of the decorative layer to illuminate the light-permeable recesses of the decorative layer. The light-conducting layer can thus be a light guide that extends, in particular flatly, on the back of the decorative layer and into which the light is radiated laterally. The light sources of the light element, for example RGB LEDs, can thus be arranged laterally on the light-conducting layer and radiate their light laterally into the light-conducting layer. The light-conducting layer then radiates the light onto the back of the decorative layer to illuminate the light-permeable recesses of the decorative layer. The light-conducting layer can, for example, be the aforementioned transparent or translucent carrier.

A transparent or translucent protective and/or optical layer can be provided on the front side of the decorative layer, which is designed as the visible side. The protective and/or optical layer comprises, for example, varnish or polyurethane (PUR) or plastic or is formed, for example, from a varnish or polyurethane (PUR) or plastic.

The invention is explained in more detail below with regard to further features and advantages based on the description of an embodiment and with reference to the accompanying schematic drawing.

1 shows a molded part 10 according to the invention designed as a decorative and/or trim part for the vehicle interior in a schematic sectional view.

The molded part 10 comprises a decorative layer 11 with a front side 12 designed as a visible side and a rear side 13 opposite the front side 12. The decorative layer 11 comprises a transparent or translucent decorative layer 14 on its front side 12 and an opaque layer 15 on its rear side 13. In the opaque layer 15, transparent recesses 16a, 16b, 16c are formed, which allow light radiated onto the rear side 13 of the decorative layer 11 to be guided through the opaque layer 15. The recesses 16a, 16b, 16c can be filled with a transparent or translucent material.

In the example shown, a transparent or translucent stabilizing layer 20, for example made of fleece and/or adhesive, is arranged between the decorative layer 14 and the opaque layer 15 on a rear side 23 of the decorative layer 14, so that the opaque layer 15 is arranged indirectly via the stabilizing layer 20 on the rear side 13 of the decorative layer 14. Alternative embodiments do not have such a stabilizing layer 20.

Examples include 1 schematically shows a first translucent recess 16a, a second translucent recess 16b and a third translucent recess 16c. Cross sections through these recesses 16a, 16b, 16c are shown, i.e. they can be lines that extend into and out of the plane of the drawing. The recesses 16a, 16b, 16c are basically identical in the example shown except for the dimensions; they extend through the opaque layer 15 and thereby enable light transmission. The three recesses 16a, 16b, 16c are distinguished based on the differences in terms of the back side 13 of the decorative layer 11 arranged color layers 17a, 18a, whose assignment to the respective recesses 16a, 16b, 16c is described below.

It is also possible that two or three of the recesses 16a, 16b, 16c shown are a continuous, curved line and different sections of this curved line form the recesses 16a and/or 16b and/or 16c. The recesses 16a and 16b can also each be a line and the recesses 16c represent an intersection point of these two lines. For example, the first recess 16a can form a first symbol and/or decoration that is visible on the front side 12 of the decorative layer 11 with appropriate backlighting and the second recess 16b can form a second symbol and/or decoration that is visible on the front side 12 of the decorative layer 11 with appropriate backlighting. In this case, the recess 16c can be an intersection point of the first recess 16a with the second recess 16b, so that the first and second symbols and/or the decoration also have an intersection area, provided that the recesses 16a, 16b, 16c are irradiated with light of a correspondingly suitable wavelength.

The first translucent recess 16a is covered on the back 13 of the decorative layer 11 with a first color layer 17a formed by the first color 17, so that the first translucent recess 16a forms a first color filter 19a for light impinging on the back 13 of the decorative layer 11. The second translucent recess 16b is covered on the back 13 of the decorative layer 11 with a second color layer 18a formed by a second color 18, so that the second translucent recess 16b forms a second color filter 19b for light impinging on the back 13 of the decorative layer 11. The third translucent recess 16c is covered on the back 13 of the decorative layer 11, first by the first color layer 17a and then by the second color layer 18a, so that the third translucent recess 16c forms a third color filter 19c for light striking the back 13 of the decorative layer 11. The first color 17 and the second color 18 are different colors, for example complementary colors. The three color filters 19a, 19b, 19c differ accordingly in terms of the wavelength spectrum they block and allow to pass through. The color layers 17a, 18a are formed, for example, by colored foils. However, they can also be printed color layers 17a, 18a, for example.

A transparent or translucent carrier 21 is arranged on the back 13 of the decorative layer 11. The carrier 21 can, for example, be injection-molded, cast or glued on. In the area of the color layers 17a, 18b, this carrier 21 borders on the color layers 17a or 18a, in areas without color layers 17a, 18a it borders on the back 13 of the decorative layer 11, whereby an adhesive layer can optionally be provided in all or individual areas (not shown).

The representation of carrier 21 and color layers 17a, 18a in 1 is to be understood schematically and is intended to illustrate the structure of the molded part 10. In real molded parts, the carrier 21 will adapt to the rear shape specified by the rear side 13 of the decorative layer 11 and color layers 17a, 18b and will lie directly against it, so that the shape shown in the schematic representation of the 1 The existing free space is eliminated. For example, two layers of paint can basically lie in one plane and span the respective translucent recesses or penetrate them completely or partially and fill them completely or partially with their respective color, although this does not necessarily have to be the case, for example with layers of paint formed by foils. The layers of paint can be arranged completely next to each other in one plane. It is also possible, however, that the layers of paint, as shown schematically in 1 shown, partially overlapped and thus formed a layered structure in the overlapping area, which can also - as shown - span a third translucent recess. It is possible that the colors in the overlapping area mix at least partially, for example in the case of printed color layers, but it is also possible - as shown - that the color layers remain in a layered structure, for example in the case of color layers formed from foils or also in the case of printed color layers.

A light element 24 is arranged on a rear side 22 of the carrier 21, which emits light onto the rear side 13 of the decorative layer 11 to illuminate the light-permeable recesses 16a, 16b, 16c of the decorative layer 11. Alternatively, the light element could also be or comprise a light-conducting layer of the molded part, for example the one shown in 1 shown carrier 21. Light could then be radiated laterally into this light-conducting layer, for example the carrier 21, for example from one or more RGB LEDs as the light source of the light element. The light-conducting layer then radiates the light radiated laterally at least partially onto the back 13 of the decorative layer 11 to illuminate the light-permeable recesses 16a, 16b, 16c of the decorative layer 11.

The light element 24 is a two- or multi-spectral light element 24 that can emit at least a first light color and a second light color, wherein the wavelength spectrum of the first light color differs from the wavelength spectrum of the second light color. For example, the light element 24 can be switchable at least between a first state in which it emits the first light color and a second state in which it emits the second light color.

The first color 17 and thus the first color filter 19a is coordinated with the first and second radiable light colors of the light element 24 in such a way that the light transmission for the first light color is greater than for the second light color. Conversely, the second color 18 and thus the second color filter 19b is coordinated with the first and second radiable light colors of the light element 24 in such a way that the light transmission for the second light color is greater than for the first light color. In particular, it can be provided that the first color 17 and the second light color are coordinated with one another in such a way that the light transmission of the second light color through the first color filter 19a is at least almost zero, and that the second color 18 and the first light color are coordinated with one another in such a way that the light transmission of the first light color through the second color filter 19b is at least almost zero. In this case, when the first light color is emitted by the light element 24, the first symbol and/or decoration is visible on the front side 12 of the decorative layer 11, while the second symbol and/or decoration is not visible or at least barely visible. Conversely, when the second light color is emitted by the light element 24, the second symbol and/or decoration is visible on the front side 12 of the decorative layer 11, while the first symbol and/or decoration is not visible or at least barely visible. Due to the overlap of the two color layers 17a, 18b in the area of the third recess 16c, the third color filter 19c can block the transmission of both the first light color and the second light color. If this is an intersection area of the first and second symbol and/or decoration, this intersection area on the front side 12 of the decorative layer 11 appears dark or black.

For example, the first color and the first light color can be "red" and the second color and the second light color can be "blue". If the red first light color is generated by the light element 24, the first color filter 19a lets the light through, while the second color filter 19b and also the third color filter 19c block the light. In this case, the first symbol and/or decoration in red is therefore visible on the front side 12 of the decorative layer 11, while the second symbol and/or decoration is not or hardly visible, and the area of the front side 12 assigned to the third recesses 16c also appears dark. If the blue second light color is generated by the light element 24, the second color filter 19b lets the light through, while the first color filter 19a and also the third color filter 19c block the light. Thus, in this case, the second symbol and/or decoration is visible in blue on the front 12 of the decorative layer 11, while the first symbol and/or decoration is not or barely visible, and the area of the front 12 associated with the third recesses 16c also appears dark. If a mixed light or another light color is generated by the light element 24, the brightness and color of which symbol and/or decoration and also the cutting area associated with the third recesses are visible on the front 12 of the decorative layer 11 depends on the wavelength spectrum of this light color and the transmission spectrum of the color filters 19a, 19b, 19c. It is possible, for example, for both symbols to be visible in different colors; in addition, the cutting area can also have a different color if necessary. By varying the light color generated by the light element 24 accordingly, changing designs can be realized on the front 12 of the decorative layer.
