  • Publication number: 20020093181
    Abstract: The invention relates to a method of producing a vehicle interior lining, especially a dashboard having a carrier part and, attached to the carrier part, a gas bag module containing a gas bag carrier and a gas bag that has a folded package section. The gas bag, together with its package section, is placed into a gas bag receptacle that is formed on the gas bag carrier and that has an outlet opening for the gas bag. The outlet opening is at least partially closed in the area of the package section by a rigid part. An outside surface of the carrier part is foam-encapsulated with a plastic layer in a state in which the gas bag module is connected to the carrier part. Moreover, the invention relates to a vehicle interior lining.

  • Patent number: 6416079
    Abstract: A knee restraint device for vehicles has a base, a knee protector component which is movable toward the knees of a vehicle occupant, and a drive structure for driving the knee protector component toward the knees of a vehicle occupant. The drive structure is arranged between the base and the knee protector component. Further, a limiting- and positioning structure is provided for limiting the travel of the knee protector component towards the knees of a vehicle occupant and for positioning the knee protector component relative to the knees of a vehicle occupant. The limiting-and positioning structure is fastened to the base and is constructed in one piece with the knee protector component. The limiting-and positioning structure is deformable on activation of the drive structure and has a predetermined rigidity, this rigidity-being sufficient so as to prevent any change in shape of the limiting-positioning structure under its weight.
