  • Patent number: 9428129
    Abstract: A front structure of a vehicle comprises a pair of side members arranged in a longitudinal direction of the vehicle, a pair of crash boxes arranged at front ends of the side members, and a body back-up structure located at a rear end of the front portion. The front structure is adapted to give an impact response curve with deceleration versus time, when subjected to a full frontal barrier impact at 35 mph according to USNCAP. The impact response curve comprises in sequence: a first phase during which deceleration increases, a second phase forming a first peak level of the deceleration, a third phase during which the deceleration is less than during the second phase, and a fourth phase forming a second peak level of the deceleration, during which fourth phase the deceleration is greater than during the third phase.

  • Publication number: 20040211286
    Abstract: A pedal arrangement (1) for a vehicle, comprising a pedal arm (2) being pivotally arranged in a pedal bracket structure (6, 7) which defines a pivot axis (3) for said pedal arm (2) and which is adapted to be fixedly mounted in said vehicle, and a stop element (14) mounted on said pedal arm (2) so that it faces the rear direction of said vehicle. The stop element (14) is mounted on the pedal arm (2) at a position chosen so that, in the event of a collision, said stop element (14) comes into contact with an existing beam structure (13) extending generally transversally in said vehicle. The invention also relates to a vehicle comprising a pedal arrangement (1) of the above-mentioned type. By means of the invention, an improved pedal arrangement is provided, which reduces the risk for injury to the driver's feet.
