  • Patent number: 7766420
    Abstract: The present invention aims at providing a vehicle body front-part structure which can efficiently disperse an impact load acting on the front part of a vehicle. In the vehicle body front-part structure in accordance with the present invention, a portion 6a of a radiator support supporting an upper part of a radiator arranged in the front part of a vehicle 2 is connected to a skeleton 9 of the vehicle body by a pair of first radiator support supporting members 4 which support it from both sides in the vehicle width direction, and second radiator support supporting members 11, 12 which are arranged on the inner side of the pair of first radiator support supporting members 4 in the vehicle width direction and support it from the backside.

  • Patent number: 7735870
    Abstract: A front structure 1 of a vehicle body has a shock absorber receiver 13 projecting forward from a dash panel 3, which is located at a position corresponding to a shock absorber 8 in a vehicle width direction and in a vehicle height direction. In the front structure 1 of the vehicle body, the shock absorber receiver 13 restricts backward movement of the shock absorber 8 upon a collision of a vehicle 2, so that a collision load acting on the shock absorber 8 can be efficiently dispersed to a framework of the vehicle body while being transmitted through the shock absorber receiver 13 to the dash panel 3. When the shock absorber 8 moves backward upon the collision of the vehicle 2, the shock absorber 8 comes into contact with the shock absorber receiver 13, and the distance becomes shorter between support points of the shock absorber 8 than before, so as to enhance flexural rigidity and reaction force.

  • Publication number: 20100013266
    Abstract: An impact beam that absorbs an impact of a vehicle collision is provided in a vehicle door, at a position between an inner panel and an outer panel. The impact beam has a wavy portion that undulates in the height direction of the vehicle door. The center axis of the wavy portion extends along the longitudinal direction of a vehicle.

  • Publication number: 20090256389
    Abstract: An object of the present invention is to provide a vehicle end structure capable of more reliably receiving a load upon a collision in a vehicle body of the frame construction. The vehicle end structure of the present invention is one constructed near a front end (or rear end) of a framework of a vehicle and is characterized by comprising a pair of body frame members 1 extending in an anteroposterior direction of the vehicle body; a bumper reinforce 3 hung at ends of the pair of frame members 1; a pair of brackets 4 located on the center side of the vehicle with respect to the ends of the pair of frame members 1 and projecting outwardly and laterally from the respective frame members; a pair of outer pillar members 5 extending downward from the respective brackets 4; a cross member 6 hung between the pair of outer pillar members 5; and a pair of inner pillar members 7 joining an upper surface of the cross member 6 to the respective frame members 1.

  • Publication number: 20080122255
    Abstract: An objective is to provide a vehicle body structure enabling side members to absorb impact in a simple configuration even in the event of a collision between vehicles with different bumper heights. The vehicle body structure to be installed in a front part or in a rear part of a vehicle is provided with a flexural portion disposed in each side member extending in the anteroposterior direction of the vehicle and having a vertical bending strength smaller than that of the other part, and is also provided with a pendent portion hung on a lower part of the side member on the outer end side with respect to the flexural portion and having an anteroposterior bending strength larger than the bending strength of the flexural portion.

  • Patent number: 7201249
    Abstract: A vehicle front structure of the present invention has a pair of side members longitudinally located on right and left sides of a vehicle, and a pair of sub side members juxtaposed to the respective side members and adapted to receive a impact load in the event of a frontal collision after the side members receive the impact load. In this vehicle front structure, the side members first receive the impact load and then the sub side members juxtaposed to the side members also receive the impact load after a certain interval, in collaboration with the side members. Therefore, vehicle deceleration increases in two stages. Since the vehicle front structure has such sub side members, the magnitude of deceleration in the second stage upon collision can be made greater than that in the first stage, and it becomes feasible to make a decision on activation of occupant protection apparatus well.
