In another variant of the method for producing a cladding element according to one of the previously described embodiments with ambient lighting according to one of the previously described embodiments, the following method steps may be provided:

• Laminating the textile layer with the plastic film as the first support layer to a decorative composite,
• Thermoforming into a preform having a three-dimensional shape,
• • cutting to a final size,
• Back molding of the preform to produce a second support layer and
• • Mounting the point light source with preferably a light emitting diode (LED) as a light source on the side facing away from the field side of the second support layer.

in this connection is compared to the method described above, the light source, here punctiform and Favor is formed with an LED as a light source, after the rear injection, so that here a previous thermoforming of the Textile composite without flat Light source, i. without luminescent film takes place. It can, however also be provided that combines both methods together be by before the thermoforming the planar light source, in particular the electroluminescent film is applied after thermoforming Injection molding in the multi-component injection molding process for installation the light guide and thereafter the point light source is preferred LEDs is mounted. This allows the lighting device then two different types of luminaires, a flat and a punctiform Flares, can have. Naturally can also be provided several LEDs.

The Provided back molding of the preform is to stabilize serve the preform. This can be done in a multi-component injection molding process at least one area of the field is back-injected with a plastic to be different from the rest Plastic or from the rest Plastics and is preferably suitable as a light guide. Here, the optical fiber plastic, for example, a polycarbonate be. The light guide can thus also light rays in the Feed field, the electroluminescent at least over a Be at least partially transparent designed and / or should not cover the field in the area of the light guide. This can be after the back molding of the preform one or more lamps, in particular a light-emitting diode (LED), so mounted in the cladding element be that the light source or the light source to the light guide is or will be connected.

By the use of the multi-component injection molding process is the subsequent assembly process of the light guide and a necessary separate injection mold saved for its production. It only needs the bulbs, here preferred LED, later to be assembled.

The Combination of several bulbs, like the mentioned LEDs and the electroluminescent film can in the field various optical Signals are fed, which have a different information content have and therefore can be controlled differently. in this connection can, as for example in a B-pillar, the upper inlet of the Seat belt edged in the cladding element of the field in which the electroluminescent film generates a signal, that on the location of the opening indicates and after a certain time after plugging in the Ignition key goes out, while an LED a sign for the seat belt permanently while illuminated the operation of the vehicle.

By receives the thermo-forming the preform by the plastically irreversibly thermally deformed Plastic film corresponding to the geometry of the later components, rigid shape. Due to the influence of temperature can also be a lighter Flow the materials to be deformed are achieved. Thus, the preform can subsequently by means of a simple inexpensive Method, such as punching, contoured to final dimensions finished get cut.

The three-dimensional preform is inserted into the injection mold for contouring into the mold and back-injected. This procedure offers the advantage that the preform is not subject to any relative movement in the injection mold, so it does not have to be shaped by a high injection pressure, as in the conventional injection molding technique. This is the decorative textile product not damaged. Thus, the three-dimensional deformation takes place in a back-injection upstream process step, which is carried out as a low-pressure process under a lower deformation pressure and therefore represents a textile layer-friendly process. Another advantage of the presented method is that the already cut edges of the preform are enclosed and sealed during injection molding of the plastic melt, so that a possible flaw, setting up the edges of the decor composite, can be avoided. For thermoforming, the decorative composite can be thermoformed with or without electroluminescent film with simultaneous heat treatment.

Around for example, light meterware for the plastic film and the To be able to use textile layer, may after lamination or after the application of the electroluminescent already done a first crop.

In The sectional views are the individual elements in their proportions presented so that they are more easily recognizable in their location and function are. The proportions shown are thus not actual Conditions.

The cladding element 1 has a decorative composite D from a first support layer 3 and a textile layer pointing inwards in the installed position 4 on. The decorative composite D extends seamlessly over the ambient lighting 2 , wherein the first support layer 2 and the textile layer 4 each formed in one piece. The first supporting layer 3 and the textile layer 4 are by means of an adhesive layer 5 forming transparent adhesive laminated together to the decorative composite D. The ambient lighting 2 is with a lighting device 6 provided, which is in each case arranged in the exemplary embodiments on the side facing away from the interior of the decorative composite D. To that through the lighting device 6 The light emitted as undisturbed as possible is the first supporting layer 3 transparent. The textile layer 4 is semi-transparent in these embodiments, so that by the lighting device 6 emitted light attenuated can enter the interior of the car.

Exemplary is the effect of the dim light on the basis of the 1 to 7 illustrated two embodiments of the cladding element 1 shown. This shows 1 the first embodiment of the connecting element 1 in daylight with the lighting device switched on 6 However, thanks to the dim light in daylight, no illumination on the inside of the cladding element is recognizable. On the other hand are in 2 which the same connecting element 1 in darkened surroundings, due to the darkening 2 through the lighting contraption 6 illuminated fields 7 recognizable. This is surrounded by the centrally arranged field 7 an opening 8th , which, as in the other embodiments of the cladding element 1 , to serve for introducing a belt, not shown here. The second field 7 Illuminates an upper central section of the cladding element.

The same situation is in the 5 and 6 shown in which the second embodiment of the cladding element 1 is shown. In addition to the fields already mentioned 7 is another circular field 7 displayed, which has a greater luminosity than the other two fields 7 so that the circular field 7 by daylight ( 5 ) and in a darkened environment ( 6 ) is visible. For this purpose, the lighting device 6 different lighting mechanisms, which are explained below.

In the in 3 shown sectional view according to the section line III-III in 2 is the area of the upper middle field 7 shown. The illumination device in this case has an electroluminescent device 9 with an electroluminescent film 10 as a light source. The electroluminescent film 10 is with its larger side surface with the decorative composite D, or with the installation position in the interior of the car facing away from the first support layer 3 connected. The electroluminescent film 10 has a conventional structure with two electrodes, a front electrode 11 and a return electrode 12 on, and one between the electrodes 11 . 12 arranged dielectric 13 , By applying a certain supply voltage to the electrodes 11 . 12 is in the dielectric 12 generated by luminescence light.

By laminating and printing is an optimal adhesion between the individual layers 11 . 12 . 13 the electroluminescent film 10 and the front electrode 11 on the first support layer 3 achieved, so that the laminate L easily to the three-dimensional shape of the cladding element shown in the figures 1 can be brought to a preform V. Thanks to the optimal adhesion, it is also possible to transform into more complicated three-dimensional shapes with small edge radii, so that the three-dimensional shape shown in the figures can only be regarded as exemplary. The decorative composite with applied electroluminescent device 9 is after its shaping with a second supporting layer 16 provided, which has been applied on its outside by injection molding.

In 4 is a variant of the first embodiment of the connecting element 1 shown, in which case additionally a motif layer 17 is provided between the first support layer 3 and the front electrode 11 is arranged. The motif layer 17 can, as by individual sections 18 schematically indicated having a character, image, pattern or the like. Thus, the character or the like can be transmitted through the transmitted light of the lighting device 6 on the textile layer 4 be projected.

The 5 to 7 show a second embodiment of the connecting element 1 , The second embodiment differs from the first embodiment essentially in that the lighting device 6 in addition to a planar light source in the form of the electroluminescent device 9 with the electroluminescent film 10 and a punctiform light source in the form of two light-emitting diodes (LED) 19 that passes through a light guide 20 are optically connected to the decorative composite D. To the light-optical connection of the LEDs 19 to illustrate are the LEDs 19 with her light part 21 partially drawn embedded in the light guide, while its connection part 22 stands out freely. Provided, however, but not shown for clarity, that the light-emitting diodes 19 with her connection part 22 are taken in a corresponding version and connected to a supply voltage source. Again, a control is not shown here is provided, the light-emitting diodes 19 controls according to an assigned function.

The light guide 20 protrudes through the electroluminescent in this embodiment 10 until the first supporting layer 3 , By means of the LEDs 19 For example, certain operating conditions of the not shown here and through the opening 8th guided belt are displayed so that their display is visible in daylight and in a darkened environment, while those by electroluminescent 10 furnished fields 7 , as already stated, are visible only in a darkened environment and thereby the position of the opening 8th show in a darkened environment.

In a further, not shown here variant of the second embodiment of the cladding element 1 can, as in the 4 illustrated variant of the first embodiment, a motif layer may be provided, which is applied to the outside of the first support layer. The motif layer may also be before laminating the first backing 3 be applied to the decorative composite D on the side facing in the installed position inward side of the first support layer. The motif layer 17 is printed by screen printing in the embodiments shown here. However, the motif layer can also be applied in any other printing process or in the form of a film.

In the 8th to 10 is a third embodiment of the cladding element 1 with an additional modification ( 10 ). Here, the third embodiment has only two point-shaped light sources in the form of two light-emitting diodes 19 on, which, as in the second embodiment, via a light guide 20 are optically connected to the decorative composite D. In contrast to the second embodiment, the third embodiment of the connecting element 1 no surface light source. In the sectional view in 10 according to the section XX in 8th , in addition to the in 9 in a sectional view according to the sectional course IX-IX in 8th shown variant of the third embodiment of the cladding element 1 , a motif layer 17 on. The motif layer 17 is between the first support layer 3 and the second support layer 16 or between the light guide 20 and the first support layer 3 arranged. The motif layer 17 points in the area of the light guide 20 a motif in the form of a character, image, pattern or the like, which by individual bright sections 18 is indicated. The area of the motif layer 17 between the two support layers 3 . 16 is here as an opaque aperture 23 carried out to scatter the light emitted by the LEDs 19 To avoid emitted light and a visually sharp image on the textile layer 4 to be able to project.

The second supporting layer 16 is, as in the other embodiments, by injection molding on the three-dimensionally deformed connecting element 1 applied. To generate the in the second support layer 16 integrated light guide 20 the multi-component injection molding method is used, the one for the light guide 20 related plastic is a polycarbonate.

In the 11 and 12 the production of the cladding element is based on a simplified schematic sequence and associated pictorial signs 1 in its first embodiment ( 11 ) and in its third embodiment ( 12 ). Both processes have in common that the textile layer 4 with a plastic film, which is the first supporting layer 3 should give, with a transparent, the adhesive layer 5 resulting adhesive to the decorative composite D is laminated.

After that, in the first exemplary embodiment, the procedure according to FIG 11 an application of the electroluminescent film 10 by screen printing, where also at the same time the necessary contacts 14 and trace 15 can be applied. The resulting laminate L is then cut to a pre-pass. In a further method step, the laminate is formed by thermoforming, wherein the plastic of the first support layer 3 thermally cured and gives the resulting preform V a certain stability, which allows further processing of the preform V without loss of form. After thermoforming, the crop is cut to final size. Thanks to the stability of the preform V, the cutting is done by simple machine punching.

In a subsequent step, the back injection of the second support layer follows the installation position in the back of the preform, whereby the preform V reaches its final stability. For generating the light guide provided in the second and third embodiments 20 which is in the second support layer 16 is integrated, is used for injection molding a multi-component injection molding method, wherein the light guide 20 forming plastic is a light-conducting polycarbonate. Both methods thus provide an installable, stable finished part F.

Subsequent to the injection molding takes place in the in 11 process shown the assembly of the point-shaped luminous element in the form of light-emitting diodes 19 so in the finished part F that the light emitting diodes 19 light-optical to the light guide 20 are connected.
