  • Patent number: 7390039
    Abstract: A bumper absorber for protecting pedestrians is formed into a W-shaped cross-sectional configuration, as taken along a direction which is orthogonal to a longitudinal direction of the bumper absorber. The W-shaped cross sectional configuration has portions in which a front notch portion, an upper rear notch portion, and a lower rear notch portion overlap with one another in a vertical direction of a vehicle. Ribs are formed respectively at the upper rear notch portion and the lower rear notch portion, and a triangular notch is formed from a vehicle rear side at each of the rib. Further, the ribs 30 are formed at the upper rear notch portion and the lower rear notch portion so as to be separated from each other at predetermined intervals in a longitudinal direction of the bumper absorber, namely, in a transverse direction of the vehicle. With this structure, a rise in impact load acting on a pedestrian who is hit by a bumper can be controlled.

  • Patent number: 7226097
    Abstract: A bumper absorber for protecting pedestrians (20) is formed into a W-shaped cross-sectional configuration, as taken along a direction which is orthogonal to a longitudinal direction of the bumper absorber. The W-shaped cross sectional configuration has portions in which a front notch portion (22), an upper rear notch portion (24), and a lower rear notch portion (26) overlap with one another in a vertical direction of a vehicle. Ribs (30) are formed respectively at the upper rear notch portion (24) and the lower rear notch portion (26), and a triangular notch (32) is formed from a vehicle rear side at each of the rib (30). Further, the ribs 30 are formed at the upper rear notch portion (24) and the lower rear notch portion (26) so as to be separated from each other at predetermined intervals in a longitudinal direction of the bumper absorber, namely, in a transverse direction of the vehicle. With this structure, a rise in impact load acting on a pedestrian who is hit by a bumper can be controlled.

  • Patent number: 6279982
    Abstract: When a rear seat is moved forward, a front leg is swung forward around a roller arm. When the front leg of the rear seat is swung forward by a predetermined angle, a hook provided in the roller arm is detached from a round bar portion of a striker so that a roller is moved downward along a guide rail. Further, as the roller is moved downward along the guide rail, the front leg of the rear seat is swung forward around the roller arm. Therefore, a radius of rotation of the seat is reduced when the rear seat is moved to a position for storage on a vertical-front-side floor surface.

  • Patent number: 6015856
    Abstract: A composite resin material exhibiting excellent physical properties, which is formed by adding semi-rigid or rigid polyurethane resin waste to a thermoplastic reactive resin, a nonreactive resin, a polymer alloy or the like. A first kind of the composite resin material is composed of a crosslinking polyurethane resin and a reactive resin, a nonreactive resin or a polymer alloy, which is formed by kneading the crosslinking polyurethane resin and the reactive resin, the nonreactive resin or the polymer alloy at a predetermined temperature or more. A second kind of the composite resin material is composed of a hydrolysis product of crosslinking polyurethane resin and a solid filler, which are mixed with a nonreactive resin and a polymer alloy by kneading.

  • Patent number: 5958988
    Abstract: A cross-linked polyurethane resin powder includes a powder including particles made from a hard or a semi-hard polyurethane resin. The particles have a superficial portion and an internal portion disposed inside the superficial portion, and involve cross-linked bondings therein. Part of the cross-linked bondings are unchanged, and another part thereof are broken to result in activated groups. At least part of the activated groups are exposed on the superficial portion of the particles. The cross-linked polyurethane resin powder is produced by hydrolyzing a hard or semi-hard polyurethane resin in the presence of water and in a temperature range of from a hydrolysis temperature of the resin to a liquefying temperature thereof, and by applying a predetermined shearing force to the resin. The cross-linked polyurethane resin powder can disperse well in resinous substrates, and can upgrade the physical properties of the resulting recycled products.
