Abstract
A bumper crossmember comprising a wave structure oriented in the vertical direction (z direction), wherein the wave structure comprises at least three apex structures which extend in the bumper crossmember longitudinal direction and are adjacent in the vertical direction. This crossmember comprises a first length section that follows its longitudinal extent, at least one second length section that follows its longitudinal extent, and at least one transition section that is arranged respectively between these length sections. In the second length section, the wave structure is inverted with respect to the first length section, in that the opening direction of the apex structures switches in the transition section. In the transition section, there is at least one additional apex-forming structure, the apex of which is offset in the frontal direction (x direction) with respect to a frontal plane (yz-plane) in which at least two apex structures that are adjacent in the longitudinal sections lie.
