Having Impact Absorbing Means Patents (Class 280/784)
  • Patent number: 6866115
    Abstract: A front body structure is provided to restrain a collision load, which has been applied on a front wheel by a vehicle front collision, to be concentrated on a front end of a side sill excessively. In the structure, a front energy absorbing member 23 is attached to a back face of a lateral end of a bumper 21. A recess 18 is formed by a front end of the side sill 7 and a front face of an outrigger 15. A rear energy absorbing member 19 is attached into the recess 18. The outrigger 15 connects the side sill 7 with a front side member extension 5 joined to the rear end of a front side member 3. At the vehicle front collision, the front energy absorbing member 23 interferes with the right-and-front part of the front wheel 1 to allow the left-and-front part of the front wheel 1 to interfere with the side face of the front side member 3 and also allow the rear part of the wheel 1 to interfere with the rear energy absorbing member 19.

  • Patent number: 6764099
    Abstract: In order to have an external force heading from the front toward the occupant received, a bumper member extending substantially along the length of the vehicle is disposed under or by the sides of the cabin (riding space). The shock absorbing members are connected at the rear ends of the bumper member. Even in the case of the vehicle in which it is difficult to dispose the shock absorbing member at the front portion of the vehicle within the range of the length of the vehicle for example, when an impact load is exerted to such a vehicle, the impact load may be efficiently absorbed. As a consequent the riding space for an occupant can be maintained. The shock absorbing body may be constructed of an upper shock absorbing member and a lower shock absorbing member. The upper and lower shock absorbing members may be formed of two types of members having different crushing features.

    Abstract: A cab body mounting (100) in a vehicle has a frame-side bracket (102) attached to a chassis frame side rail (18) and a body-side bracket (104) attached to a cab body rail (16). An elastomeric bushing (108) and a fastener (109) associate brackets 102, 104 so as to allow limited motion between them accompanied by bushing deformation. Bracket (102) has an upright wall (110) that is spaced a distance from an end (16E) of rail (16). A sufficiently large relative acceleration of the body on the frame, such as during a frontal impact, will cause an edge portion of bracket (104) to abut wall (110), which arrests further movement of the bracket in the fore-aft direction, and thereby shares the loading that is being imposed on the mounting due to the acceleration force. This occurs before the stress in the shank of fastener (109) reaches the characteristic maximum allowable shearing stress for the fastener material.

    Abstract: A multi-section support rail has a first section with an outer circumferential wall, a parallel inner circumferential wall and a transverse web extending longitudinally therealong, a second section hollow tubular section with an outer circumferential wall and a parallel inner circumferential wall. The outer circumferential walls are substantially identical dimensionally. The sections are joined at mating surfaces. The joined sections are pre-bent at the second section and then hydroformed to a final desired shape. The transverse web retains the extruded dimensions throughout the hydroforming process.

  • Patent number: 6547020
    Abstract: A battery mounting assembly for mounting batteries to a vehicle. The battery mounting assembly has lower battery tray and an upper battery tray disposed below and above one another respectively. The battery mounting assembly is constructed to move and deform in predetermined ways when it is subjected to relatively large forces such as might occur when the vehicle is involved in a traffic accident. The battery mounting assembly has one or more bumper components intended to protect batteries mounted to the battery mounting assembly from being subjected to a direct impact. Steel components of the battery mounting assembly are coated with an elastomer that has a high electrical resistance.

  • Patent number: 6523885
    Abstract: The deformation member (1) is disposed between a longitudinal member (2) and a cross member (3) of a motor vehicle, with the cross member having a horizontal central longitudinal plane which is vertically offset to the horizontal central longitudinal plane of the longitudinal member (2). The deformation member includes an elongate, hollow base body (4) of polygonal cross section and a height which is greater than its width, and an upper and a lower reinforcing shell (14, 19) which are connected through welding to the base body (4) via the longitudinal edges of their legs (13, 18). The end walls of the lower reinforcing shell (19) are closed by cover plates (22, 24). The deformation member (1) can be coupled via a plate (23) with the longitudinal member (2) of the motor vehicle.

  • Publication number: 20020153719
    Abstract: Disclosed is a collision energy absorbing structure of a vehicle capable of relieving impact by using a tubular pipe member having equally-sized rectangular cross section and equal plate thickness and including no inside ribs and by adding a suitable trigger, and being easily manufactured at a low cost. By forming a cutout portion on the left side of the front end portion of the collision energy absorbing structure, the deformation starting portion is provided. The cutout portion is formed at parts of three flat plate portions comprised of one of the four flat plate portions and corresponding opposite portions thereof. The general portion, which follows the deformation starting portion, is tubular with rectangular cross section and has a closed cross-section structure.

  • Patent number: 6460889
    Abstract: A stopper 1 is fixedly mounted on and projects from an outer surface of that portion of a side frame 7 disposed in the vicinity of a front wheel 14. A reinforcement 2 is mounted on an inner surface of that portion of the side frame 7, on which the stopper 1 is mounted, thereby reinforcing the stopper 1. At the time of a collision of a vehicle, a rear side 17 of an outer periphery of the front wheel 14 strikes against the stopper 1, and also the movement of the stopper 1 is prevented by the reinforcement 2, thereby limiting the movement of the front wheel 14. Therefore, the deformation of the side frame 7 and so on toward the vehicle frame is reduced.

  • Publication number: 20020125710
    Abstract: In order to have an external force heading from the front toward the occupant received, a bumper member extending substantially along the length of the vehicle is disposed under or by the sides of the cabin (riding space). The shock absorbing members are connected at the rear ends of the bumper member. Even in the case of the vehicle in which it is difficult to dispose the shock absorbing member at the front portion of the vehicle within the range of the length of the vehicle for example, when an impact load is exerted to such a vehicle, the impact load may be efficiently absorbed. As a consequent the riding space for an occupant can be maintained. The shock absorbing body may be constructed of an upper shock absorbing member and a lower shock absorbing member. The upper and lower shock absorbing members may be formed of two types of members having different crushing features.
