Definitions

  • the invention relates to Lenkraddekorschalen and Interieurzierieri according to the preamble of claim 1 and a method for their preparation.
  • German Patent Application 29 44 797 A1 a curved strip, in particular for the interior of motor vehicles, and a method for their preparation known.
  • the visible after installation outer layer of this bar consists of a wood veneer overlay, which is applied to a supporting layer of plastic.
  • the method for producing this strip is characterized in that a wood veneer overlay is inserted into an injection mold adapted to the later strip outer surface and locked in this position and that the strip is molded after spraying with a plastic under high pressure and cooling.
  • this method has the disadvantage that the wood veneer can tear, and that through these cracks but also through pores in the wood veneer plastic can be pushed through. This can lead to rejects during production or rework is required.
  • the invention has for its object to reduce rejects and rework in Lenkraddekorschalen and Interieurzierierin. According to the invention that is achieved according to the features of claims 1 and 7.
  • the Holzfumier on the inside, ie on the side facing the plastic carrier layer is provided with fleece.
  • the fleece prevents the tearing of the wood veneer or the film and the pushing of plastic through the wood pores or other defects, such as diarrhea branches, and the spherical deformability of the wood veneer is improved.
  • the thermal load on the wood or decor is reduced and discoloration is largely excluded.
  • fleece lamination proves to be helpful to compensate for the different properties longitudinal and transverse to the wood fiber and to prevent tearing along the wood fiber in susceptible wood, eg mahogany species. Overall, rework and rejects are thus reduced.
  • the nonwoven as a layer with a minimum thickness of 0.1 mm and a maximum of 2.0 mm. Furthermore, it is expedient that the wood veneer has a thickness of less than 0.6 mm.
  • mounting and mounting aids such as hooks, pins, springs, grooves, mandrels centering and energy directors are integrally formed on the plastic carrier layer and that the plastic carrier layer consists of a thermoplastic or a thermoplastically processable natural substance.
  • a method for producing steering wheel decorative shells and interior trim elements using a wood veneer or a film is characterized in that the wood veneer or the film is first provided on the inside with a fleece, and then back-injected with plastic in an injection mold.
  • Nonwoven layer is thus laminated to the wood veneer before introduction into the injection mold, for example by gluing.
  • the wood veneer is introduced into the injection mold and can be because of the nonwoven layer better spherical deformation than without this layer.
  • provided with the fleece wood veneer can also be deformed before the injection molding process, ie, be brought into a desired shape for the intended purpose. This procedure is particularly useful when veneers are used, which are easily damaged by deformation. Such damage can especially in the case of injection in an injection mold, since this process is similar to a deep-drawing process, in which the material is heavily stressed. If the wood veneer provided with the fleece is already deformed before the back-injection process, a deformation process can be selected in which the risk of damage to the veneer is low.
  • Lenkraddekorschalen and Interieurzieriata thus represent sandwich arrangements in which veneer laminated with fleece, preferably glued, and in which the fleece is molded behind plastic with a positive fit.
  • wood veneer is ground before deformation. Sanding can be done before or after lamination. As a result, the grinding effort on the finished part, which usually has to be carried out manually because of the often complex shape, is minimized. Furthermore, wood veneer may be flexed prior to insertion into the injection mold, i. be made flexible to make it easier to deform. The wood fibers of the veneer are broken by rolling.
  • FIG. 1 shows a longitudinal section through a wooden decorative trap
  • FIG. 2 shows a cross section through the wooden decorative dish according to FIG. 1
  • the wooden decorative shell consists of wood veneer 1 which has been provided with a fleece layer 2. These two layers were provided with a plastic carrier layer 3 in an injection mold. From Fig. 2 it can be seen that the wood veneer 1 is strongly curved. With this strong curvature there is a risk that the veneer breaks. The nonwoven layer 2, however, stabilizes the wood veneer such that it can be bent so sharply without cracks, as shown in FIG. 2. At the plastic carrier layer 3 mounting aids, such as the hooks 4 shown, are formed.
