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: A bumper device can reduce a weight of a reinforcement member more than a weight of a conventional reinforcement member while sufficiently absorbing a given impact energy. A size “b” between both side mounting portions where the reinforcement member is mounted on a stay is set greater than a size “a” between both side longitudinal wall portions of a side frame, both outer longitudinal walls of the stay are inclined such that both outer longitudinal walls are opened toward the reinforcement member, and the distance between the inner longitudinal walls is set substantially equal to the distance between the both side longitudinal wall portions of the side frame.

Abstract: A shock absorbing member for a vehicle is designed to absorb the impact energy in a plastic deformation manner to absorb the axial compressive load. The shock absorbing member includes a hollow member whose cross-section is roughly constant and whose axis is adapted to extend forward and rearward of the vehicle. A flange is formed on the hollow member roughly along the axis of the hollow member and projects by an amount increasing gradually from one side toward the other side of the axis.

Abstract: A first frame section is hollow and has a substantially uniform polygonal cross-sectional shape. An axial load is applied to the first frame section. A second frame section is hollow and has a substantially uniform polygonal cross-sectional shape. The axial load is transmitted from the first frame section to the second frame section. A transmitting portion is provided in at least one of the first and second frame sections. The transmitting portion receives the axial load that acts on each edge of the first frame section and transmits the axial load to each edge of the second frame section.

Abstract: A bumper reinforcement structure includes a bumper reinforcement element placed at least at the front end or rear end of a vehicle body and fixed to a side member of the vehicle body. The bumper reinforcement element has a closed hollow side cross-section, extends in the vehicle lateral direction and is formed of any one of a light alloy and a steel. A concave or convex portion is formed on at least one surface of the bumper reinforcement element so as to change the shape of the cross-section of the bumper reinforcement along the vehicle lateral direction.

A size “b” between both side mounting portions where the reinforcement member is mounted on a stay is set greater than a size “a” between both side longitudinal wall portions of a side frame, both outer longitudinal walls of the stay are inclined such that both outer longitudinal walls are opened toward the reinforcement member, and the distance between the inner longitudinal walls is set substantially equal to the distance between the both side longitudinal wall portions of the side frame.

Abstract: Load is applied to a bumper reinforce. Two hollow crash boxes are coupled to the bumper reinforce. Each crash box has a substantially constant cross section, an axis and an open end. When load is applied to the bumper reinforce, each crash box is plastically deformed in the axial direction for absorbing the load. The bumper reinforce includes projections. Each projection corresponds to one of the crash boxes and faces part of the open end of the corresponding crash box. The projections reduce the load at the beginning of plastic deformation.
