Description

TECHNICAL FIELD

[0001] The invention relates to an interior trim part for a motor vehicle, having an at least sectionally light-transmissive main body which is covered on one side by a viewable side by a decorative cover layer which is at least partially transparent to view, wherein at least one light-impermeable component is connected to the edge region and / or the backside of the light-transmissive main body, such that at least one transmission region of the light-transmissive main body remains, which is transparent to the light beam of at least one light-emitting device arranged in the interior trim part, wherein the light-impermeable component is configured in a frame-like manner, such that in a cross-section of the interior trim part the light-impermeable component and the light-transmissive main body only overlap in an edge-side overlapping region. BACKGROUND

[0002] Such an interior trim part is known from DE 20 2015 106 328 U1. Specifically, it is proposed in this document for a decorative part for a vehicle interior which is configured as a shaped part, comprising a decorative cover layer with a decorative layer. The decorative layer has an opening which extends through the decorative layer. At the backside of the decorative layer there is a light-transmissive first print layer, at the backside of which a light-impermeable second print layer is arranged. A transparent overmolding is bonded to the backside of the decorative cover layer, to which a transparent or translucent first carrier part can be injection-molded, which can be transparent to light. In order to avoid scattered light, a further light-impermeable carrier part is injection-molded to the first carrier part. However, scattered light can escape through the overmolding arranged between the decorative cover layer and the first carrier part.

[0003] A display element for a gear selector switch of a vehicle is described in DE 10 2016 224 847 A1, which has a carrier element with a carrier recess for receiving a light source. Furthermore, there is a transmission element with a symbol recess representing at least one three-dimensional symbol. The transmission element is light-transmissive in the region of the symbol recess and is arranged at the carrier element such that the symbol recess is opposite the carrier recess with the light source. SUMMARY

[0004] Starting from the above-mentioned prior art, the invention is based on the task of providing an interior trim part for a motor vehicle which can be improved in terms of its scattered light tightness.

[0005] The present task is solved by the interior trim part according to the invention. Advantageous configuration variants or extensions of the invention can be derived from the remaining embodiments.

[0006] The invention starts from an interior trim part for a motor vehicle, which has an at least sectionally light-transmissive main body. The light-transmissive main body is covered on one side by a viewable side by a decorative cover layer which is at least partially transparent.

[0007] Here, at least one light-impermeable, i.e. non-transparent, component is connected with the edge region and / or the back side of the light-transmissive main body. This is done in such a way that at least one transmission region of the light-transmissive main body remains, which can be arranged in the light beam transmission of at least one light-emitting device in the interior trim part.

[0008] In terms of the decorative cover layer, it should be mentioned that the decorative cover layer comprises at least one, preferably a plurality of, pigment layers. Each pigment layer is preferably a lacquer layer. For example, the decorative cover layer can be applied in a so-called IMD intaglio printing method (IMD = in-mold decoration). This method is very cost-effective and well suited to mass production. Since the method is known, it should not be discussed in detail here.

[0009] The invention now proposes that the decorative cover layer is guided up to the light-impermeable component, as seen in a cross section of the interior trim part.

[0010] In other words, the decorative cover layer is guided with one end side or edge side up to the light-impermeable component. There is no gap between the end side or edge side of the decorative cover layer and the light-impermeable component.

[0011] By the features described above, a basic prerequisite is created for the light-transmissive main body to be optically encapsulated in the surrounding edge region in such a way that it can only still be transmitted by the remaining transmission region and thus undesired lateral escaping scattered light can be avoided.

[0012] According to a first expansion of the invention, a light guide is provided, into which light of the at least one light-emitting device can be coupled in. Here, the light guide is received in a receiving space of a light-impermeable holder and is covered by the light-transmissive main body. This is done in such a way that the light guide is completely received between the light-impermeable holder and the light-transmissive main body.

[0013] Such an expansion is advantageous for a compact design and helps to avoid undesired scattered light.

[0014] According to a further constructional variant of the inventive concept, the light guide is configured in a planar manner. Light of the at least one light-emitting device is coupled in laterally into the light guide and coupled out of the light guide again in the direction of the light-transmissive main body. Here, the light guide can advantageously rest on the bottom of the light-impermeable holder.

[0015] Such a constructional solution contributes to a compact construction and to uniform light emission.

[0016] "Planar" is to be understood in the sense of the application as follows: the light guide has a planar extension in two mutually perpendicular directions, which is several times the thickness of the body in each direction.

[0017] The light outcoupling can here preferably be effected via light outcoupling structures which are introduced into the light guide at the side thereof facing away from the light emission direction or which are distributed in the light guide as interference sites for the scattered light.

[0018] In order to ensure a good functional action of the interior trim part, i.e. constant light emission properties in all driving conditions, it is proposed according to a further development that the light guide is clamped between the base of the holder and the light-transmissive body. This also contributes to a very compact construction of the interior trim part.

[0019] It is however also conceivable in a further constructional solution of the inventive concept that the light guide is clamped in the holder, such that the light guide is clamped between the base of the holder and a flexible latching means. The latching means can for example be configured as a latching projection.

[0020] In addition to high functional reliability, this has the advantage that the interior trim part can be maintained, if necessary, for servicing purposes.

[0021] If there is a clear spacing between the light-transmissive body and the light guide according to a further development, air can better circulate in the vicinity of the light guide and better cooling of the light guide, which becomes very hot in operation, can be achieved. This can also contribute to uniform light emission.

[0022] In a suitable design of the application, the light-impermeable component is welded to the light-impermeable holder. In this way, a very functionally safe, reliable connection is provided between the components. The welding is preferably carried out by ultrasonic welding, which has proven to be very reliable in practical operation.

[0023] In order to carry out a reliable welding, it is for example conceivable that a rib-like welding protrusion is injection molded at the light-impermeable component, which protrudes through an opening of the light-impermeable holder and the end of which is welded to the light-impermeable holder.

[0024] Alternatively, it is conceivable that the light-impermeable component is clipped with the light-impermeable holder. This also contributes to the maintenance friendliness of the interior trim part. The clipping can advantageously take place via latching arms on the edge side of the light-impermeable component, which latch with a more inwardly weighted latching projection onto the light-impermeable component.

[0025] In a highly suitable configuration of the inventive concept it is proposed that the decorative cover layer, the light-transmissive main body and the light-impermeable component are composite parts configured as multi-component injection-molded parts. Advantageously, the composite parts are two-component (2K) components in which the light-transmissive main body is formed from a translucent or transparent material component and the light-impermeable component is formed from an opaque, preferably black material component.

[0026] Such an expansion enables a very cost-advantageous and reliable production of the interior trim part.

[0027] According to a further configuration of the invention, the light-impermeable component is configured in a frame-like manner. In a cross-section of the interior trim part, the light-impermeable component and the light-transmissive main body overlap in a material interface, thus only in a circumferential overlap region on the edge side of the composite part.

[0028] Very advantageously, the region with the material interface is located outside the contour of the light guide in a top view of the contour of the interior trim part. In this way, the risk of optical impairments due to the collision of the different material components with each other can be significantly reduced.

[0029] In view of the minimization of defects during the flow process when injection molding, and in view of a very good optical quality, it is advantageous if the material interface extends from the circumferential edge of the composite part in such a way that the material of the light-transmissive main body continuously increases and the material of the light-impermeable component continuously decreases.

[0030] In other words, the thickness of the light-transmissive main body thus continuously decreases (not abruptly) towards the circumferential edge.

[0031] Finally, a motor vehicle is also to be protected by means of the invention, which has at least one interior trim part according to the invention. For example, the interior trim part can be a component of the dashboard and / or the door interior trim of a motor vehicle.

[0032] The preferred embodiments of the present application are shown in the figures and explained in more detail in the following description with reference to the figures. Further advantages of the present application also become apparent from this. The same reference numerals (even if in different figures) also relate to the same, comparable or functionally identical components. Here, the respective or comparable properties and advantages are also realized even if not repeated or referred to. The figures are not or at least not always to scale. In some figures, the scale or spacing can be exaggerated in order to make the features of the embodiments more clearly visible. BRIEF DESCRIPTION OF DRAWINGS

[0038] Figures 5 to 9 The interior trim part in different embodiments is shown in a sectional view rotated 90° clockwise and can be compared with the sectional plane running V to IX in Figure 4

[0039] Fig. 10 (a to f) shows a diagram of the method steps for manufacturing the interior trim part. DETAILED DESCRIPTION

[0040] Reference is first made to Figure 1 In this figure, the interior space of the motor vehicle K in the area of the cockpit 2 can be seen. From the interior space of the motor vehicle K, the dashboard 3, the steering wheel 4, the side door trim 5 and the center console 6 can be seen. Furthermore, an elongate, panel-like interior trim part 1 is shown, which extends horizontally over the dashboard 3 and along the door trim 5.

[0041] The general structure of the interior trim part 1 is now described in more detail with reference to Figure 2 The sectional view is selected according to the sectional plane running II in Figure 4

[0042] ​​​​Thus, it can be seen with the aid of the figures that the interior trim part 1 has a light-transmissive main body 10. The light-transmissive main body 10 is preferably transparent, i.e. configured glass-clear. It is also conceivable for the light-transmissive main body 10 to be colored and / or configured only transluzent.

[0043] Furthermore, the light-transmissive main body 10 is configured in a planar manner. Thus, the face extension of the light-transmissive main body is several times its thickness.

[0044] One side of the light-transmissive main body 10 is covered by a decorative cover layer 11. Thus, the decorative cover layer 11 constitutes the visible side S for a vehicle occupant located in the interior space of the motor vehicle K.

[0045] The decorative cover layer 11 is preferably a decorative cover layer produced in the so-called IMD method (IMD = In-Mold Decoration). This decorative cover layer can consist of one or more paint or lacquer layers. The decorative cover layer 11 is configured to be partially light-transmissive and can in this way contain a transmittable pattern, transmittable characters and / or symbols or the like.

[0046] The light-transmissive main body 10 is preferably injection-molded onto the decorative cover layer 11, i.e. fixedly connected thereto. This method is explained in more detail later.

[0047] Furthermore, the light-transmissive main body 10 is covered on its back side in the edge region by a light-impermeable component 12. The light-impermeable component 12 is injection-molded onto the light-transmissive main body 10, i.e. also fixedly connected thereto.

[0048] Thus, the light-transmissive main body 10, the decorative cover layer 11 and the light-impermeable component 12 form a composite component MK consisting of a plurality of components which are connected to one another in a non-releasable manner. The circumferential edge of the composite component MK is designated by R.

[0049] The light-impermeable component 12 is configured in a frame-like manner in terms of contour. This results in the production of a transmission region LB which can be transmitted by a light beam L which can be produced by one or a plurality of light-emitting means 15, preferably light-emitting diodes, which are located in the interior trim part 1.

[0050] The composite component MK or its light-impermeable main body 12 is fixedly connected, preferably welded, to a likewise light-impermeable holder 13. The holder 13 can preferably be provided with a reflective interior cover and thus acts as a reflector.

[0051] To this end, the light-impermeable component 12 has a welding rib 12a which is plugged through a through-opening 13c of the holder 13 and is converted into a welded protrusion 12a' by a welding process, thereby producing a form fit between these components.

[0052] In this way, a substantially closed receiving space 13 a is formed between the composite component MK and the holder 13 , in which receiving space the optical fiber 14 is received.

[0053] The holder 13 therefore serves, in a manner not shown in detail here, to hold the optical waveguide 14 . The optical waveguide 14 is also of planar design and rests on the bottom 13 b of the holder 13 .

[0054] The dimensions of the receiving space 13 a are preferably designed in such a way that a clear distance a remains between the light conductor 14 and the light-transmissive body 10 .

[0055] The optical waveguide 14 is also preferably designed as a transparent body. On its rear side facing away from the light-transmitting body 10, the optical waveguide may have a light coupling-out structure (not shown in detail), via which light coupled laterally into the optical waveguide 14 by the luminous means 15 is coupled out again in the direction of the light-transmitting body 10. The holder 13 designed as a reflector can also facilitate this.

[0056] As can be seen from the figure, the light-transmitting body 10 is completely covered by the decorative coating 11 at the visible side S. In particular, by means of Figure 3 It becomes clear that the decorative coating 11 is guided up to the light-opaque component 12. The decorative coating 11 rests against the light-opaque component 12 with an edge or end face.

[0057] Preferably, the light-transmissive body 10 , the light-opaque component 12 and the decorative coating 11 are configured such that in the region of the circumferential edge R, a surface 11 o of the decorative coating 11 and a surface 12 o of the light-opaque component 12 adjoin each other flush.

[0058] However, in contrast to this exemplary embodiment, it is also conceivable that the light-transmitting body 10 is designed to be slightly smaller, so that the surfaces 11o and 12o do not adjoin each other flush, but rather a so-called shingled structure is obtained. However, this shingled structure is only achieved by the light-opaque component 12 protruding beyond the light-transmitting body 10 at the edges (see reference numerals 10 ′, 11 ′).

[0059] In any case, it is important that the decorative coating 11 is guided up to the light-opaque component 12. When the decorative coating 11 is guided toward the light-opaque component 12, no gap remains between the decorative coating 11 and the light-opaque component 12 through which undesired scattered light could escape.

[0060] As a result of such a structure, in the edge region of the composite component MK, a light-technical encapsulation of the light-transmissive body 10 is achieved by the decorative coating 11 on one side and the light-opaque component 12 on the other side.

[0061] Thereby, essential prerequisites are created for very effectively avoiding undesired scattered light.

[0062] Thus, by means of Figure 2 and Figure 3 It becomes clear that a circumferential overlap region is provided by the composite component MK In this overlap region, the material components of the light-transmissive main body 10 and the light-impermeable component 12 abut against one another, forming a material interface G.

[0063] It can be seen from the illustration that the material interface G extends at least section-wise inwardly from the circumferential edge R of the composite component MK in such a way that the material of the light-transmissive main body 10 continuously increases, while the material of the light-impermeable component 12 continuously decreases.

[0064] In the manufacturing process, the flow properties of the materials are very advantageously influenced by this material progression, whereby material defects, such as discoloration problems in the light-transmissive main body 10, can be avoided as far as possible.

[0065] Furthermore, a plurality of back-side fixing protrusions 13d should also be mentioned, at the end of which the interior trim component 1 can be fixed in the interior space of the motor vehicle K by means of fixing means 13e, for example a screw connection.

[0066] In Figure 4 , the interior trim component is shown in a top view from the visible side S looking towards the contour of the interior trim component.

[0067] Here, the frame-like circumferential light-impermeable component 12 is shown in dashed lines, thereby forming a window-like see-through region LB and a circumferential overlap region

[0068] Furthermore, an elongate planar light conductor 14 is shown, at opposite end sides of which light-emitting means 15 are arranged, the light of which can be coupled into the light conductor 14.

[0069] Further embodiments for the interior trim component should now be described in more detail by means of Figures 5 to 9 It becomes clear, in particular, how the light conductor 14 is reliably fixed. In the figures, the light-emitting means 15 and the fixing protrusions 13d are no longer shown for the sake of clarity.

[0070] Thus, in Figure 5 , the interior trim component 1a can be seen, in which the light-impermeable holder 13 is configured in the form of a basin and the composite component MK formed from the light-transmissive main body 10 and the light-impermeable component 12, in particular the light-impermeable component 12, is connected to the light-impermeable holder 13 via the solder joint 12b. The solder joint 12b is preferably produced by ultrasonic welding.

[0071] Furthermore, it can be seen from the figure that the material interface G initially extends straight and parallel to the rear surface of the light-transmitting body 10 starting from the circumferential edge R. However, if it is Figure 2 and Figure 3 As can be seen, the course of the material interface G is preferred.

[0072] In the present embodiment, the light conductor 14 is clamped between the bottom 13 b of the light-tight holder 13 and the rear side of the light-transmissive body 10 .

[0073] With the help of Figure 6 An exemplary embodiment for an interior trim component 1 b is shown in which, unlike the preceding exemplary embodiments, the connection between the composite component MK and the light-impermeable holder 13 is realized via a snap-in connection.

[0074] Specifically, latching arms 12 c are injection-molded onto the light-proof component 12 on the rear side, said latching arms engaging from behind with latching means 12 d designed as latching projections in latching recesses 13 h on the edge of the light-proof holder 13 .

[0075] The connection between the composite component MK and the light-tight holder 13 is designed to be detachable. After the connection is detached, the optical waveguide 14 and, if necessary, the luminous means 15 can be removed.

[0076] and Figure 6 In comparison, according to Figure 7 In the interior decoration component 1c, the direction of the material interface G is constructed to be able to Figure 2 and Figure 3 The course of the material interface G shown in FIG is comparable. Therefore, the advantages achieved thereby will not be discussed again here.

[0077] However, as in Figure 8 As shown in the figure using the interior trim part 1d, it is also conceivable that the light conductor 14 is releasably clipped to the light-proof holder 13. For this purpose, the light-proof holder 13 has a plurality of latching arms 13f that project toward the light-transmitting body 10. The latching arms 13f are arranged within the outer, surrounding wall of the light-proof holder, as viewed from the outline of the interior trim part 1d, thereby creating an intermediate space 13i. The latching means 13g of the latching arms 13f, which are designed as latching projections, latch across the light conductor 14 resting on the bottom 13b of the light-proof holder 13 in a latching manner. The length of the latching arms 13f is selected so that they form an (additional) support surface 13k for the light-transmitting body 10.

[0078] This ensures a secure fit of the light conductor 14 in the interior trim component 1 d and a safe support of the light-transmitting body 10 , wherein a clear distance a is additionally provided between the light conductor 14 and the light-transmitting body 10 .

[0079] The latching connection between the composite component MK and the light-tight holder 13 is again achieved via the latching arms 12 c engaging in the latching recesses 13 h of the light-tight holder 13 .

[0080] Finally, in Figure 9 , an interior trim component 1f is shown in which, unlike the previous exemplary embodiments, the composite component MK or the light-tight component 12 is welded to the light-tight holder 13. Here, too, this is achieved via a welding rib 12a injection-molded onto the light-tight component 12, which projects through a through-opening 13c in the light-tight holder 13 and whose end, after the feed movement Z, is transformed by means of a welding tool W into a welding projection 12a'.

[0081] Here too, the course of the material interface G corresponds to the principle that, starting from the edge region R of the composite component MK, at least in sections, the material of the light-transmissive body 10 increases continuously, while the material of the light-opaque component 12 decreases continuously.

[0082] With the help of Figure 10a From now on, a preferred production method for the interior trim parts 1 or 1 a to 1 f will be explained in more detail.

[0083] Firstly, a film-shaped decorative coating 11 produced in the so-called IMD method on a carrier film T composed of thermoplastic plastic (for example a PET film, ie a PET film composed of polyethylene terephthalate) is placed in a mold.

[0084] The decorative coating 11 consists of one or more pigment coatings. The pigment coating is preferably designed as a lacquer coating. Furthermore, the design is such that the decorative coating 11 has light-transmitting and light-opaque areas. These areas can be used to provide patterns, characters, symbols, or the like.

[0085] The mold includes a first mold forming part 20 and a second mold forming part 21 ( Figure 10a ).

[0086] The carrier film T together with the decorative coating 11 is reshaped by closing the mold forming parts 20 and 21 ( Figure 10b ).

[0087] Subsequently, the decorative coating 11 is post-injected with a light-transmitting material 10m (also a thermoplastic) at a temperature of approximately 200° C. (Figure 10c ).

[0088] After this, i.e. after the light-transmissive material 10m has cured to the light-transmissive body 10, the mold sections 20 and 21 are again separated from one another, and the mold section 20 is turned through 180 degrees Figure 10d ).

[0089] Subsequently, from the opposite side, the other mold section 22 is guided toward the first mold section 20. From now on, the light-transmissive body 10 can be post-injected with the non- light-transmissive material 12m (also a thermoplastic) as the second material component Figure 10e ).

[0090] After the non-light-transmissive material 12m has cured to the non-light- transmissive component 12, the mold sections 20 and 22 are again separated from one another, so that the finished composite part MK consisting of the decorative cover 11, the light-transmissive body 10 and the non-light-transmissive component 12 can be removed. In the process, the decorative cover 11 located on the composite part MK is detached from the carrier film T (see Fig. 1a) Figure 10f ).

[0091] Since, in the preceding method steps, the second material component was not injected onto the decorative cover 11 together with the first material component, but in the second mold cavity of the mold section 22 onto the light-transmissive body 10, no line of confluence of the different material components is visible on the surface of the decorative cover 11 or of the visible side S of the composite part MK. For this purpose, the second material component (material 12m) is injected with as little mold offset as possible onto the mold parting and tear edge of the first injection (material 10m).
