Definitions

  • the invention relates to a single or multilayer plastic skin as a surface covering of coated objects. Likewise, particularly suitable methods for producing such a plastic skin are disclosed as well as a covering part coated with such a plastic skin for the interior of a motor vehicle.
  • Grained, patterned, or finely textured plastic skins are widely known as surfaces for articles and are used e.g. B. used for interior trim in vehicles, often as relatively soft foamed films with a pleasant feel about for the cladding of dashboards or the inner shells of doors, etc. In appropriate adjustment of strength and design, such films are of course also for other high-quality coated goods used.
  • thermoplastic film present as sheet material is provided with the aid of an embossing roll having a three-dimensionally structured embossed surface, that is to say a grained "leather surface”.
  • mold-falling mold skins here more or less rigid plastic moldings are referred to, for example, by various sintering or spraying in Molds are made in which one or more liquid or powdered components are placed in a mold and ausreagieren / harden there. Tool-falling mold skins are thus also produced by rotational sintering, for example by methods for producing so-called slush skins.
  • these tool-dropping methods provide the possibility of having the surface texture / texture, i.
  • the surface of the plastic skin such as the appearance of a scar, and the geometry of the entire component in a single molding process during manufacture.

  • Both the sheeting and the skins are usually provided on the back with a layer of plastic foam, either after embossing and / or after insertion / deep drawing in the component form (web goods) or already in the
  • EP 1 190 828 A1 describes a method for the production of tool-deposited fusible bodies / cast bodies, such as dashboards, door panels or glove boxes, in which a divided lower mold is initially and at least partially laid out with an elastic film which covers the seams present in the mold, and which has on its inside a grain, for example, a leather texture.
  • the elastic film is sprayed with a reactive mixture, which then forms the outer skin of the component, before further reinforcements or foam layers are applied by various different spraying or melt molding methods.
  • the molded skins are treated with the support structure after the manufacturing process again clean, ie possibly existing skin edges are cut off and dashboard z. B. then the necessary recesses or holes for instruments, switches, trim holders, radio, etc. manufactured. Thereafter, for example, all switches, instruments, bulbs, speakers and signal elements are individually installed in the dashboard and possibly wired.
  • moldings such as handle or storage troughs, surface parts with special decor, moldings and their respective brackets.
  • the object was to provide a plastic skin, on the one hand as possible such elaborate steps of further processing as possible and on the other hand combines a high component integration with a pleasing appearance of the plastic skin.
  • molding and / or ornamental elements are already embedded in the plastic skin or within the plastic composite of the plastic skin.
  • Such elements in the plastic skin eliminates the subsequent installation of the same in the form of separate trim, recessed grips, etc., which in turn would have to be securely connected as individual elements with the plastic skin.
  • the forming and / or decorative elements are arranged on the outer surface of the plastic skin. So they are visible from the outside, which is required for decorative elements, or reachable for the occupants of a vehicle, which is useful, especially for handle elements.
  • a further advantageous embodiment is that the forming and / or decorative elements are designed in the form of decorative strips or strips. This eliminates z. As in a dashboard, the subsequent complex installation such parts that can be bent quickly when handling often due to their lightweight construction.
  • a further advantageous embodiment is that within the plastic skin mold elements are arranged, which partially dilute the plastic skin, preferably plastic strips or cords. With the use of these elements, it is also possible to incorporate "functions" such as a thinned line in the dashboard for an air bag system positioned behind this area, inflating the air bag and tearing the plastic skin along the line of tearing -Bag free.
  • plastic skin is formed as a rolled and / or embossed thermoplastic continuous film.
  • Such an endless film can then easily before or after cutting for the subsequent deep-drawing process in a component form - for example, on their component form facing later outside - are provided with appropriate shape and / or decorative elements, which then melt in the heat of the deep drawing process.
  • a further advantageous embodiment of such a plastic skin is that the plastic skin is formed as mold-falling molded skin.
  • a molded skin which generally results from sintering, spraying or filling processes within a mold, it is possible in a simple manner to introduce molds and / or ornamental elements. This can for example be done in a particularly advantageous manner by one or more liquid or powdered plastic components are placed in a reaction form and react or harden there. The resulting skin is then backfoamed with a layer of plastic foam, preferably polyurethane foam, and possibly connected to a support frame. In a first preliminary process step while the shape and / or decorative elements are inserted into the reaction form and positioned there in their distance to the subsequent surface of the plastic skin.
  • the form and / or ornamental elements are integrated in the most easily predeterminable positions in the plastic skin, dimensionally stable and optically perfectly integrated into the surface of the plastic skin.
  • An advantageous development of the production method is that powdered plastic components are placed in a heated reaction form and melted there in a sintering or slushing process, preferably sintered by rotation.
  • the slow sintering process of the finely powdered granules at elevated temperature during rotation results in particularly secure confinement in or reliable melting onto the mold and / or ornamental elements.
  • a plastic powder is in the heated and rotating mold / reaction mold and then melts against the heated wall portions of the mold.

  • the connected tool parts ie lower tool box and upper mold must be rotated about an axis of rotation.
  • the filled with plastic powder lower tool box the so-called “Bücket” rotates so with, so that the plastic powder trickles over the inner surface of the heated upper mold box, so that the plastic powder during Rotational sintering on the upper mold (reaction form) melts and binds the mold and / or decorative elements during melting and curing.
  • the plastic skin according to the invention can be used as a trim part for the interior of a vehicle, preferably as a dashboard, as well as illustrated by an exemplary embodiment of a tool-covered plastic skin, which further explains the invention.

  • the hatched areas 2, 3 of the molded skin are excess mold edges, which are removed in the post-processing.
  • the hatched area 4 is also cut out in the post-processing and then forms the recess for the display instruments to be used later.
  • the moldings 5, 6, and 7 are integrated and melted into the outer surface areas of the molded skin. These elements are first inserted into the reaction mold, ie, the upper mold of a mold for the rotary sintering process, and positioned there in such a way that that they essentially complete with the surface of the molded skin or easily survive.
