1. A bumper crossbeam, comprising:
a wave structure aligned in a vertical direction (z-direction), the wave structure comprising at least three vertex structures that extend in a longitudinal direction (y-direction) of the bumper crossbeam and are adjacent in the z-direction,
the bumper crossbeam having a first longitudinal section following its longitudinal extent and at least one second longitudinal section following its longitudinal extent, as well as at least one transition section arranged respectively between the first and second longitudinal sections,
wherein the wave structure in the second longitudinal section is inverted compared to the first longitudinal section in that the opening direction of the vertex structures changes in the transition section, and
wherein at least one additional vertex-forming structure is provided in the transition section, and a vertex of the additional vertex-forming structure is offset in a front direction (x-direction) with respect to a front plane (y-z plane) in which at least two vertex structures that are adjacent in the first and second longitudinal sections lie in the transition section.
