  • Patent number: 6601902
    Abstract: A motor vehicle cockpit is prefabricated and contains a flat shaped piece serving as a mounting plate for a visible shell, a heating or air-conditioning system and operational elements. An impact protection is formed by a box-section of the motor vehicle body that extends under the front edge of the windscreen and a cross-member. The impact protection is completed by the flat shaped piece that couples to the box-section and the cross-member, preferably coupled with a linear introduction of force. In the event of a vehicle frontal impact, the flat shaped piece and coupled box-section and cross-member absorb the energy of impact.

  • Patent number: 6467220
    Abstract: A device for fastening a lock module including at least one lock part, an actuating part, and a covering on a module support which is provided for a two-shelled vehicle door and supports the function modules of the vehicle door. A supporting arm which is elastic in a longitudinal direction, polydirectionally pliable, and thus capable of being readjusted, is fastened to the module support. The supporting arm fixes the lock module in the installation position in an unsupported and resilient manner via a supporting plate. The supporting arm is constructed with a tubular shape in order to accommodate a Bowden pull wire for the actuating part of the lock module and/or electric cable.

  • Patent number: 6318752
    Abstract: The invention relates to an instrument panel for motor vehicles, made of a thermoplastic material and providing an invisible cover for an airbag system which, as seen from the inside of the motor vehicle, is positioned behind the instrument panel (rear side). The instrument panel is characterized in that it has a weakened section on the rear side which defines an opening area in the instrument panel for the airbag and fully surrounds said opening area, and in that it has an ejection channel for the airbag fixed to it. The opening area in the instrument panel designed for the airbag is connected with the ejection channel by means ofa polymer hinge. Both the ejection channel and the polymer hinge are fixed at least to the opening area of the instrument panel designed for the air bag by means of a welded material. The instrument panel, ejection channel and polymer hinge are made ofa thermoplastic material having the same polymer basis but flexibilized in different ways.

  • Patent number: 6274219
    Abstract: A multilayer formed part having acoustic damping properties is composed of a binder containing carrier fibrous web of natural fibers and/or synthetic fibers of low compression, which is covered at both sides with cover layers and/or decorative layers. The carrier fibrous web across the surface thereof is interlaced with prismatic regions of any suitable cross section, with prismatic regions having increased strength and not being connected with each other, and being connected to the covering layer and/or the decorative layer in a shearing resistant manner.

  • Patent number: 6106003
    Abstract: The invention relates to an interior trim panel for motor vehicles fitted with an airbag. Said panel consists of a dimensionally stable supporting member (3) with a film cover (1) on its visible face, and is provided with a tear-open airbag penetration area for expansion of airbag at the point where the airbag is installed (9'). The airbag penetration area is defined by notches (5) in the supporting member (3). The support member has a guide channel (3'), which is integrally formed at the rear, for the expanding airbag. The opening (12) of this channel is covered by the supporting member and the film cover on the visible face which is devoid of any markings. The notches of the guide-channel opening define a pocket-like opening penetration area during airbag expansion. Said notches form a pattern of lines consisting of a center line and side lines which branch off parallel to or diagonally from the center line.

  • Patent number: 5658511
    Abstract: A method of manufacturing molded parts, preferably having the same wall thickness, from mixtures of cellulose and/or lignocellulose fibers with more than 20% by weight of thermal binders, in which the molded article results from application of heat and pressure to fiber mat prefabricated therefrom. In a first step, the fiber mat undergoes preliminary compression as a planar, endless matted fiber fleece, with only a small degree of compression of the fiber composite, the matted fiber fleece containing at least 2% by weight of a binder which cross-links under heat, its "start-off temperature", i.e. the temperature at which cross-linkage begins, being lower than the softening temperature of the thermoplastic binder. The cellulose and/or lignocellulose fibers are provided, before production of the fiber composite, with a surface finish of the cross-linking binder.

  • Patent number: 5549327
    Abstract: A shock absorber for improving the safety in passenger compartments of motor vehicles during impact accidents. It is intended that the impact between the outer skin of bodywork parts such as doors and the associated inner lining in the passenger compartment shall be reduced.The shock absorber is in the form of an impact pot, in such a way that the energy absorption, at least to a considerable extent, is effected via a plurality of chronologically successive shearing procedures of the absorber material during an impact. The impact pot is subdivided into shearing zones for the successive shearing procedures, which are defined along enclosed curves. The impact pot is in the shape of a stepped pyramid or terrace arrangement with optional plan projections.

  • Patent number: 5525283
    Abstract: A method for the production of laminated moldings, such as internal linings or panellings of motor vehicles and the like, and dimensionally stable parts in which a support part is provided with a surface lamination and in which initially a preform having the same volume as the support part, but not having the same surface area with respect to the final shaping, is produced. Utilizing the inherent production heat, the preform is then connected by pressure action to the lamination by back-embossing with the thermoplastic material of the support part and is given its final shape by material flow processes. The invention improves back-embossing in the production of laminated moldings in such a way that with reduced embossing forces the surface-unitary adhesion of the lamination to the support part is improved and the risk of bubble formation is eliminated.

  • Patent number: 5275865
    Abstract: An overhead lining for vehicular inside roof linings of passenger cars is described, which is designed as self-supporting, integral shaped bowl. The overhead lining is made by compressing a mat of refuse nonwoven fabric, while exerting a pressure thereon at an elevated temperature. For this purpose, the refuse nonwoven fabric is made up of a mixture of at least 30 percent up to a maximum of 90 percent of partially stretched polyester fibers with parts of polyester high-bulk fibers, supplemented to 100 percent. The weight per unit area of the finished shaped bowl is between 600 and 1,200 grams per square meter, and the thickness is between 1 and 10 millimeters. The shaped bowl, on its one visual surface, is lined without an additional cement being used. The wall thickness of said shaped bowl may vary across its surface, and compaction of said shaped bowl, in the regions of its mounting elements, may be higher than in other regions.

  • Patent number: 5200128
    Abstract: Process for producing binder-containing fibrous mats from lignocellulose fibres or the like together with stabilizing additives is described. These mats are then generally processed by hot pressing to shaped or moulded articles, such as for the internal lining of the passenger compartments of motor vehicles. The dry fibrous material thoroughly mixed with the binder is applied to a conveyor in such a way that there is an alternate application of several wood fibre layers and synthetic fibre layers. The accumulation densities of the synthetic fibres and the wood fibres are placed to produce a mat cross-section in accordance with a statistical distribution, or curve, which roughly corresponds to an edge-blurred, periodic comb profile. The curve base width for the synthetic, fibres is much smaller than that for the wood fibres. The individual fibre accumulations are interconnected by means of suitable adhesives.
