  • Patent number: 7201436
    Abstract: The invention relates to a composite component and a method of producing such composite component, in particular a car body attachment part for a motor vehicle, which includes an outer skin that is defined by an outer skin foil associated with the motor vehicle. An inner layer made of plastic is applied to a rear side of the outer skin foil by providing a foamed or injection-molded backing. A mounting piece is disposed in a depression of the outer skin foil and is anchored therein. An intermediate foil is situated between the mounting piece and the outer skin foil and prevents, at least in sections, any direct contact between the mounting piece and the outer skin foil.

  • Patent number: 7189450
    Abstract: A foamed vehicle component has a foamed main component and an insert. The insert serves as a fastening element and is embedded in the foamed main component by foaming. The insert, in a portion embedded in the foamed main component, is surrounded at least in sections by an elastic intermediate component. Pliability of the elastic intermediate component is larger than that of the foamed main component, so that the insert is resiliently supported in the foamed main component.

  • Publication number: 20070023947
    Abstract: A method of producing a foamed part, in particular a car body attachment part for a motor vehicle, includes the following steps. A foaming tool is provided that includes a tool bottom part and a tool upper part. An outer skin is placed in the tool bottom part and an expandable material is applied. The foaming tool is closed, with at least one portion of the outer skin being located in a gap between the tool bottom part and the tool upper part. After the foaming process, during opening of the foaming tool, the outer skin is trimmed by the foaming tool itself. The invention further relates to a foaming tool for applying such a method.

  • Publication number: 20060237994
    Abstract: A car body attachment part, when mounted to a motor vehicle, has an inner side comprising a surface portion, and an opposite, visible outer side. A method for producing the car body attachment part includes the following steps. A foaming mold is provided that includes a first tool mold die and a second tool mold die. The inner side of the car body attachment part is associated with the first tool mold die, and the outer side is associated with the second tool mold die. Next, a protective foil is inserted in the first tool mold die, at least in a region of the surface portion. The protective foil is provided with a foam backing so that the inner side in the region of the surface portion is constituted by the protective foil. The protective foil is connected with the foam backing such that the protective foil can be peeled off from the foam backing in a non-destructive manner. The car body attachment part is particularly useful as a roof module mounted to a roof of a motor vehicle.

  • Publication number: 20060208539
    Abstract: A vehicle body attachment part for a motor vehicle, in particular a roof module, comprises a large-area outer skin having first and second large-area outer skin portions that are formed from different materials. The vehicle body attachment part also includes a rear carrier layer that receives the outer skin. The first large-area outer skin portion is formed by a foil and the rear carrier layer is formed by providing the foil with a foamed backing. The carrier layer integrally extends under the second large-area outer skin portion, which is subsequently fastened to the rear carrier layer.

  • Patent number: 6938946
    Abstract: A car body part for a motor vehicle has an outer skin formed of an at least partially deformable material. An inner layer is formed of a foamed plastic. A mounting part which is placed in a recess of the outer skin and is anchored via an interlocking fit between the outer skin and a deformed portion of the mounting part. The interlocking fit may be created when the foamed plastic is expanded in a mold, which increases interior pressure within the mold and deforms the outer skin against the mounting part.

  • Publication number: 20040256889
    Abstract: A method of manufacturing a vehicle body part embeds an insert piece into a foamed layer of the body part by holding the insert piece in a foaming tool using a magnetic force. The magnetic force holds the insert piece into position, eliminating the need for any additional holding structures in the foaming tool. A body part made by this method has improved visual quality, particularly at a transition area between the insert piece and a decorative part.

  • Publication number: 20040258888
    Abstract: A method of manufacturing a composite vehicle body part includes producing an embossed portion on a foil in the part via plastic deformation. The embossed portion is formed by pressing the foil against a thin, detachable decoration negative in a deep-drawing tool or a foaming tool. The embossed portion remains visible even after a foam backing or injection-molded backing is provided on the foil.

  • Publication number: 20040247854
    Abstract: A foaming tool has a first mold part, a second mold part, and at least two cavities for producing at least two composite parts from a substrate. A compensation zone is disposed between the two cavities and is adapted to accommodate a relief zone formed on the substrate. The substrate has a first component section and a second component section adapted to be arranged in the cavities of the foaming tool. The first and second component sections receive a foamed backing of an expandable material to form the composite parts. The substrate has a relief zone between the first and second component sections to handle any stresses on the substrate and prevent surface defects in the substrate.

  • Publication number: 20040234729
    Abstract: A composite part, such as a mount-on car body panel, is manufactured as a foil part covered by a protective foil. The foil part and protective foil are both inserted into a foam die. Before the insertion, the protective foil is reworked on an outer side of the protective foil to remove rough areas. The resulting composite part has improved surface characteristics due to the reworking step.

  • Publication number: 20040169400
    Abstract: A vehicle body panel and a method for manufacturing a vehicle body panel includes a thin plastic film that is applied to a deep-drawn, film-like exterior covering before a back-foamed layer is applied to the exterior covering. When the film hardens, it improves the structural stability of the film, preventing indentations due to varying levels of shrinkage of the back-foamed layer from becoming visible on the exterior covering.
