Definitions

  • the invention relates to an interior trim part for a motor vehicle according to the type defined in detail in the preamble of claim 1. Furthermore, the invention relates to a method for producing an interior trim part for a motor vehicle.
  • EP 1 577 165 B1 discloses a method for producing a motor vehicle interior trim part, in which a metal structure which is permeable perpendicularly to its surface area for fluids is connected to a barrier layer and a further layer, wherein the barrier layer penetrates the further layer through the metal structure limited. With this method, the scope for interior trim parts of motor vehicles should be increased.
  • interior trim parts can be made with the method described therein, there is still considerable interest in interior trim parts for motor vehicles, which enable novel effects, particularly with regard to the surface effect.
  • the solution according to the invention in which the film is present in the region of the at least one breakdown of the metal layer on the outer surface thereof, makes it possible to achieve completely new optical and haptic effects in interior trim parts for motor vehicles which can not be produced with the hitherto known technical means ,
  • the result is a visible part of the surface of the interior trim part, which is visible in the at least one opening, that is visible on the outside of the interior trim part. denden film a magnifying glass effect, which leads to a depth effect that has not yet been generated.
  • a further advantage of the solution according to the invention consists in the material combination present on the outside of the inner lining part by the different material of the foil and the metal layer. On the surface of the interior trim part so there are two different materials, which additionally reinforces the effect described.
  • the use of metal is particularly advantageous because, on the one hand, metal can be easily deformed to achieve the desired shape of the interior trim part, and it also has a very high stability to give the entire interior trim part a sufficiently high rigidity.
  • the thickness of the film is 0.7 - 1, 2 mm.
  • a thickness of the film in this area has proved to be a particularly good compromise with respect to a stiffness sufficient to prevent damage to the film on the one hand and a good deformability of the same on the other hand.
  • the size of the at least one aperture is at least 2 mm, preferably at least 3 mm.
  • a method for producing an interior trim part, in particular an interior trim part according to the invention, is specified in claim 9.
  • the inner lining part can be produced in a simple and reliable manner, wherein it is particularly advantageous that during the formation of the carrier layer at the same time the film is pressed through the at least one opening of the metal layer, so that very few operations for the production of the interior trim part are required , Further advantageous embodiments and modifications of the invention will become apparent from the remaining dependent claims.
  • an embodiment of the invention with reference to the drawing is shown in principle.
  • FIG. 1 shows a schematic partial view of an interior trim part according to the invention.
  • FIG. 2 shows a section through the inner lining part of FIG. 1.
  • Fig. 1 shows a portion of an interior trim part 1 for a motor vehicle, not shown.
  • the interior trim part 1 can be mounted in the interior of the motor vehicle in the area of a dashboard, on the inside of doors and at other locations known per se.
  • the interior trim part 1 has a carrier layer 2, a film 3 arranged on the carrier layer 2 and a metal layer 4 which is arranged on the film 3 and forms the outside of the interior trim part 1, that is to say the side of the interior of the motor vehicle facing it, which are also referred to as metal part can.
  • the inner lining part 1 thus formed may have any shape in order to be adapted to the shape of the component on which the inner lining part 1 is attached.
  • the metal layer 4 has at least one opening 5, in the present case a plurality of apertures 5, which are formed in the illustrated embodiment in honeycomb form and arranged side by side. In principle, however, any shapes and arrangements of the at least one opening 5 or of the multiplicity of openings 5 over the surface of the metal layer 4 are conceivable.
  • the interior trim part 1 is preferably produced as follows:
  • the at least one opening 5 or the openings 5 are produced, for example by means of a stamping method.
  • the metal layer 4 could also be an expanded metal part.
  • the metal layer 4 is deformed, to which also known methods can be used, and preferably painted or anodized. In principle, it is of course also possible to first reshape the metal layer 4 and then introduce the apertures 5 in the same.
  • the step of painting or anodizing, by which a kind of adhesion mediation between the metal layer 4 and the film 3 is achieved, can in principle be done at any time.
  • an aluminum material is particularly suitable for the same.
  • the film 3 which is preferably made of plastic, in particular of a transparent plastic such as polymethyl methacrylate, and preferably has a thickness between 0.7 - 1, 2 mm, is also deformed, in particular thermally deformed, and thereby in one of the shape of the metal layer 4 adapted form brought. Due to this thickness of the film 3, the magnifying effect described can be achieved particularly well.
  • the film 3 can be printed in a manner not shown in order to enhance the effect described yet.
  • the metal layer 4 and the film 3 are then placed touching each other in a tool, not shown, and it is preferably applied to the film 3 by so-called back injection a material for forming the carrier layer 2.
  • This application of the material for forming the carrier layer 2 takes place in such a way that the film 3 is pressed into the apertures 5 by the applied pressure such that the film 3, as described above, forms the outer surface of the inner lining part 1 in the region of the apertures 5 or on the outer surface of the interior trim part 1 is present.
  • the tool ensures that the film 3 does not protrude beyond the outer surface of the metal layer 4.
  • a plastic material is used to form the carrier layer 2, which can be processed in a conventional manner to form the carrier layer 2. If the carrier layer 2 has a light color, the effects described above are further enhanced.
  • a diameter or a clear width of at least 2 mm, preferably at least 3 mm has proved to be advantageous. If the aperture 5 is not formed symmetrically, as shown in the present case, the smallest side length of the aperture 5 should be at least 2 mm, preferably at least 3 mm. This ensures that the film 3 passes through the apertures 5 to the surface of the metal layer 4.
