  • Films in the form of multilayer composite films for coating or surfaces of any objects are widely known in the art, including in the surface design of furniture and interior trim parts of vehicles, especially motor vehicles.
  • flexible, grained, patterned, or finely structured plastic skins are used as surfaces for the interior lining, here often as relatively soft foamed-in films with a pleasant feel, for example for the paneling of dashboards or the inner shells of doors, etc.
  • the multi-layered construction usually consists of an upper cover or decorative layer provided with the embossed or molded surface, and one or more sub-layers.
  • the cover layer is usually provided with a lacquer layer and can also be colored.
  • the CA 2 454 911 AI discloses a vehicle roof as a molded part, which is provided with strip-shaped electroluminescent elements.
  • the headliner consists of a molded carrier which is pressed with a coating film to form a component.
  • first electroluminescent elements are positioned in the carrier, guided with their connecting cables through the carrier and then covered with the applied coating film, fixed and pressed.

  • an optical layer is arranged on the back side of the cover layer which has light-transmitting, light-refracting and light-reflecting properties or a combination thereof, ie is optically active or has optical properties.
  • the transmission, refraction and reflection properties are designed so that an illumination of the optical layer, in particular a back-side illumination of the optical layer leads to a passage of light, preferably to a uniform passage of light through the cover layer.
  • the term "uniformly" is to be understood that in relation to a certain surface area, an equally strong glow and a uniform light emission from the cover layer arise.
  • the optical properties of the optical layer can also be adjusted so that over different surface areas a different intensity illumination or a different strong light emission from the cover layer is formed.
  • a wave structure or other decorative designs of the lighting can be adjusted.

  • the entire component on which the multilayer composite film is as a surface coating used as a luminous body or signal body and turned on or off as desired.

Such embossing can be carried out on one side or on both sides, so that incoming and outgoing light can be influenced accordingly.

  • the cover layer is processed with appropriately trained embossing tools or needle wheels, for example, with approximately circular or diamond-shaped needle tips, so that a kind of hole pattern with however, does not arise from the total thickness of the cover layer reaching holes, from the outside or in the section roughly comparable with blind holes.
  • Semi-perforation or decorative perforation thus describes the appearance of a perforation, but without real perforation of the surface or Oberfietzenmaterials.
  • the layer thickness of the cover layer which is reduced in the holes, always leads to the passage of light from the underlying optical film through these "thinned residual layers" being considerably more pronounced than in the non-thinned areas ,

  • a further advantageous embodiment consists in that the cover layer is perforated, preferably provided in the form of linear or sheet-like perforation patterns. This makes it easy to create decorative patterns by:

Abstract

L'invention concerne une feuille composite multicouche transparente en matière plastique utilisée comme revêtement de surface d'un objet. Cette feuille composite comprend au moins une couche de recouvrement externe au moins partiellement transparente éventuellement pourvue d'un vernis, ainsi qu'au moins une couche supplémentaire disposée à l'arrière de la couche de recouvrement. A l'arrière de cette couche de recouvrement se trouve une couche optique, de préférence une couche optique en polyéthylène téréphtalate (PET) présentant des propriétés de transmission de lumière, de réfraction de lumière et de réflexion de lumière ou une combinaison de ces propriétés, et ces propriétés de transmission, réfraction et réflexion sont conçues de manière qu'un éclairage de la couche optique, en particulier un éclairage face arrière de la couche optique entraîne un passage de la lumière de préférence homogène à travers la couche de recouvrement.
