  • Patent number: 9623910
    Abstract: There are provided a hinge pillar comprising an outer panel and an inner panel which form a closed cross section extending vertically, a hinge pillar reinforcement provided in the closed cross section, a front door attached to the hinge pillar via a pair of upper-and-lower door hinges, and a hinge bracket attaching the lower door hinge to the hinge pillar reinforcement, the hinge bracket being provided to face a front wheel in a longitudinal direction. Herein, the hinge bracket has a lower strength than a portion of the hinge pillar reinforcement where the hinge bracket is provided. Accordingly, when receiving a collision load from the front wheel, the hinge bracket changes a contact portion of the front wheel to the hinge pillar so as to guide the retreating front wheel outward in a vehicle width direction.

  • Patent number: 9604674
    Abstract: A rear pillar inner provided at a side panel inner and extending upward from a front-side upper portion of a rear wheel house, a rear pillar reinforcement joined to an outside portion of the rear pillar inner, and an outside reinforcing member connecting an outside portion of the side panel inner and the rear wheel house are provided. The rear pillar reinforcement has a rear-side pillar-reinforcement ridge portion extending vertically. The outside reinforcing member has a front-side reinforcing-member ridge portion extending vertically. A lower end portion of the rear pillar reinforcement and an upper end portion of the outside reinforcing member are joined such that the both ridge portions are arranged to align substantially straightly, when viewed from the side, and to slant in such a manner that an upper side thereof is positioned relatively forward compared to a lower side thereof.

  • Patent number: 9409605
    Abstract: A structure is configured such that a viewer hardly feels strangeness of color tone or texture even when paint mist is attached to a center pillar 3 during coating of a body outer plate. A panel surface of an outer panel 35 of the center pillar 3 has a protrusion in a middle in the vehicle vertical direction such that at least part of a lower portion of the panel surface projects toward the outside of the vehicle body relative to an upper portion of the panel surface. A start end HL of the protrusion is located at substantially an identical height to a door body upper edge line UL in at least a center portion in a pillar width of the pillar outer panel.

  • Patent number: 6793276
    Abstract: A floor is partitioned into a plurality of areas S1 to S4 by a floor tunnel portion 11, side frames 13, side sills 12, and cross members 7, 8, 15, and 16, and the rigidity of the floor panels of the areas S1 to S3 is adjusted by rigidity adjustment portions 20, 21, 22, 23, and 25. These floor panels are set such that their natural frequency in a 2×1 mode, in which two antinodes are generated in the length direction of the automobile and one antinode is generated in the width direction of the automobile, is 240 to 260 Hz. Thus, a reduction in road noise due to automobile tire cavity resonance is achieved.

  • Patent number: 5318338
    Abstract: An upper body structure of a vehicle includes a front header extending in a transverse direction of the vehicle. The front header is formed as a generally boxed channel by an upper header frame and a U-channel shaped lower header frame. A side rail extends in a lengthwise direction of the vehicle and has upper and lower rail frames connected so as to form a generally boxed channel. The U-channel shaped lower header frame and the upper rail frame are interconnected by a generally U-channel shaped rigid reinforcement structure.

  • Patent number: 5246263
    Abstract: In a rear body structure of a vehicle, a rear pillar forms a rear edge portion of an opening for a door which is formed on one side portion of the vehicle body. A rear fender is connected to the rear pillar and extends rearwardly therefrom. A suspension tower is connected to the rear fender at a distance from the rear pillar. A reinforcement is connected to upper portions of the rear fender and the suspension tower so as to extend in the longitudinal direction of the vehicle body. An impact absorbing portion is provided between the rear pillar and the suspension tower to prevent the rear pillar from being deformed in response to forward displacement of the suspension tower which is caused by a forward impact load acting on the suspension tower.
