  • Patent number: 6210147
    Abstract: This invention relates to an apparatus and method for shaping fibrous elastic bodies. The apparatus includes a preliminary shaping die and a final shaping die. A fiber material, which includes a binder fiber and a matrix fiber, is used to form the elastic bodies. The binder fiber has a lower melting point than the matrix fiber. The fiber material is placed into the preliminary shaping die and half melted to bond the unmelted matrix fiber and thereby form the preliminary shaped item. The preliminary shaped item has a preliminary shape of an objective article to be shaped. The preliminary shaped item is then transferred to the final shaping die, in which it is further heated and clamped to shape the objective article.

  • Patent number: 6003939
    Abstract: In a seat structure having a side air bag device, a longitudinal groove (36) is formed in a seat back pad (14) along the longitudinal direction of the seat back pad, and an insert wire (40) which holds a seat outer cover, is embedded in the longitudinal groove (36). Bent portions (44) are formed in portions of the insert wire (40), which portions oppose the air bag device. Each of the bent portions (44) is bent in a substantially U-shaped configuration, and a slab pad (46) is wound around an outer peripheral portion of a base portion (44A) of each bent portion. Further, the bent portions (44) of the insert wire (40) are each provided to extend rearwardly and diagonally toward the inner side of a seat back (10) so that the embedded length of the insert wire (40) embedded in the seat back pad (14) is made longer, and adverse influences on riding comfort are thereby suppressed.

  • Patent number: 5804292
    Abstract: The invention provides a laminated article such as a door trim board capable of maintaining a bonding effect for a long period of time by integrally forming a base member and a skin member without forming the skin member in the shape of a sheet and without using an adhesive, and a manufacturing method of the laminated article by which reduction in the quantity of materials to be used and simplification of manufacturing steps are achieved. A porous base member (11) molded in the shape of a door trim board and a molten resin (12melt) supplied on the surface of the porous base member are pressed between a pair of molds (31, 32) so that the molten resin (12melt) is impregnated into the porous base member at least at the front surface thereof and hardened to form a skin member (12) on the porous base member (11). In the door trim board thus obtained, the resin forming the skin member (12) and the porous base member (11) are integrated by an anchor effect of resin with a reliable strength thereof retained.

  • Patent number: 5630638
    Abstract: A seat lift mechanism in an automotive vehicle incorporates a swivel base mounted on a stationary base secured to a compartment floor of the vehicle for rotation about a vertical axis so as to be moved between a forward-facing position where the front side of the swivel base is oriented to the front of the vehicle, and a sideways position where the front side of the swivel base is opposed to a side door opening of the vehicle. A frame is supported on the swivel base for rotation therewith and a lift rack provided thereon with a passenger seat is mounted on the frame. The lift rack is connected to the frame by means of a link mechanism in such a manner that when the swivel base is retained in the sideways position, the lift rack and seat are movable from a first position on the frame to a second position close to the ground where the seating surface of the seat is maintained at an inclined angle.

  • Patent number: 5490718
    Abstract: A seat cushion of a vehicle front seat, including a cushion panel and a cushion frame, in which the cushion panel and the cushion frame are elastically held together in close proximity to a front edge portion of the cushion panel by means of a torsion spring, and are connected together at a rear portion of the cushion panel by a pair of rear-linking members which is subjected to an urging force in a tension direction by a pair of tension springs. Thus, the seat cushion can be formed with a simplified spring arrangement, and provides easy tuning of these springs because the tension spring exhibits a linear spring characteristic. Furthermore, the seat cushion eliminates pitching because the cushion frame and the cushion panel are connected together at the rear portion thereof behind a hip point of an occupant who is seated in the front seat. Moreover, the seat cushion provides a wider space for an occupant seated in the rear of a vehicle to stretch his legs.
