摘要： 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.

摘要： 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.
