  • 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: 7017978
    Abstract: The present invention the related to a shock absorption pad for a vehicle for protecting occupant's lower legs. The shock absorption pad according to the present invention on which an occupant's foot is placed is attached on a surface of a toe board. The shock absorption pad includes a first shock absorption layer provided on the occupant's foot-placing side for absorbing an impact generated in a boundary region at which an energy absorption load of a vehicle body becomes different in a deformation process of the vehicle body at a vehicle crash, and a second shock absorption part provided on the toe board's side for absorbing an impact generated in a region in which the energy absorption load is high.
