Abstract: A suspension arm made of an aluminum alloy extruded profile having a portion forming a bottom portion, portions forming at least two vertical walls, and a horizontal rib which connects the two vertical walls, wherein a suspension part lower end support portion is formed between the two vertical walls or at the bottom portion by removing a part of the horizontal rib. It is preferable to gradually change the interval between the two vertical walls in the portion in which the horizontal rib is removed.

Abstract: An energy absorbing member (12) is installed in a bumper reinforcement (4) so that one end of the energy absorbing member (12) faces the side member (3) of an automobile. During an accident, if a force is applied to the bumper apparatus (2), the energy absorbing member (12) collapses like a bellows in order to absorb this shock. The energy absorbing member (12) will reliably collapse in this desired manner under many conditions, for example, where the automobile is large and heavy or where the accident occurs under a high-speed condition. The energy absorbing member (12) is of a tubular shape with smooth and straight surfaces so that the energy absorbing member (12) can be easily produced by an extraction forming method or the like. Furthermore, the energy absorbing member (12) is installed within the bumper reinforcement (14) so that the bumper apparatus (2) projects less from an automobile body (1) in comparison to conventional bumpers.

Abstract: An automotive vehicle bumper assembly includes a pair of side members constituting part of a vehicle body, a bumper reinforcement supported on the side members and extending transversely of the vehicle body, and an energy absorber arranged on a front surface of the bumper reinforcement. The bumper reinforcement has a rectangular cross section, upper and lower walls, and an intermediate wall connecting the upper and lower walls.

Abstract: A vehicular bumper reinforcement to which a rear portion of a bumper shell mounting a lamp is secured includes a vertical front wall having a cut-out portion through which a mounting portion of the lamp is passed, a vertical rear wall having a cut-out portion through which the lamp is capable of moving at the time of a collision, and flanges provided above and below the cut-out portions and spaced apart from each other by a distance somewhat greater than the height of the lamp mounting portion. At least one hollow portion formed integral with the reinforcement is provided above and below each of the flanges.
