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.
