Definitions

  • the invention relates to a multilayer film laminate which has at least one top-lying compact decorative film of thermoplastic material as a cover film and a foam layer arranged thereunder.
  • Such multilayer film laminates also called foam films, with an outer decorative film with a grained, patterned or finely textured surface are as
  • such film laminates are applied to the surface of a carrier or a dimensionally stable support structure made of hard plastic or other materials, wherein the foam layers produce a soft and pleasant grip or feel.
  • foam layers produce a soft and pleasant grip or feel.
  • End customer usually used area, be covered with a soft foam-backed, while the lower door leaf receives about an injection molding surface or is provided separately with a different and thin foam-backed film.
  • the latter causes additional costs by providing a second production line for the door leaf and requires an additional process step with the second joining process required in the final assembly.
  • the object was to propose a multilayer film laminate, which is provided in some areas with a necessary or desirable handle-softness, while other areas with the same panel only fulfill decorative purposes, are designed according to abrasion-specific criteria and do not meet any special haptic requirements need to be able to be produced easily and with the best practices.
  • the foam layer on at least two foam layers which are arranged so that the thickness of the foam layer is changed in some areas.
  • a vehicle interior trim or a trim part with a foamed over the area or width asymmetrically with respect to the film thickness film This is e.g.
  • the thicker film area on the area of a door sill is limited and provides the necessary softness, while the thinner film area covers the door area, which only has to meet decorative requirements.
  • foam layers of the same thickness are arranged at least partially overlapping. This results in a particularly simple manufacturability without costly change in the previous manufacturing processes.
  • foam layers of different thickness are arranged side by side or at least partially overlapping.
  • foam layers are arranged adjacent to each other. This results in a very simple form of Thickness adaptation and consequently a simplest version of the production of
  • foam layers are strip-shaped, preferably formed as strips of the same width. Again, the production further simplified by the fact that only foam strips of the same width
  • Foam material need to be produced, which are then only applied accordingly.
  • a further advantageous embodiment is that individual foam layers have a different density compared to the other foam layers.
  • An advantageous method for producing a film laminate according to the invention is that a film laminate already having a thin foam layer is provided on the foamed side with further strip-shaped foam layers. This results in an improvement of the manufacturing process in the sense of integrating the production of fiction, contemporary vehicle interior trim in existing
  • Decorative film is provided on its underside with at least two mutually parallel foam layers / foam strips, preferably during the embossing of the outside of the decorative film. The application of the foam layers takes place
  • Figure 1 shows a section through a thickness transition region of a film laminate according to the invention 1 of a vehicle interior panel, which is an overhead compact decorative sheet 2 made of thermoplastic material and arranged underneath
  • Foam layer 3 has.
  • the foam layer has two foam layers 4, 5, which are arranged so that the thickness of the foam layer is changed in some areas.
  • the underside of the film laminate is applied to a carrier, not shown here.
  • a curvature of the decorative film results here in the thickened foam regions, ie towards the viewer / vehicle occupant.
  • Foam layer 3 a maximum of 2.3 mm, while the minimum thickness of only one foam layer 4 existing foam layer 3 in the right part 7 of the cutting area only a total of about 0.8 mm.
  • the foam layers 4 and 5 are here foam layers of the same thickness, wherein the foam layer 4 right portion 7 of the cutting area by rolling and embossing operations of the decorative film 2 was compressed more than this left part 6 of the cutting area is the case.
