Abstract

A bumper for an automobile includes a crossbeam which is formed from at least two separate hollow profiles, wherein the hollow profiles abut one another along a longitudinal wall and are joined with one another. The abutting longitudinal walls form a double web oriented in the longitudinal direction of the automobile. The hollow profiles may have an identical cross-sectional configuration. The hollow profiles may be roll-formed or extruded. The modular construction of the crossbeam from separate hollow profiles allows a lightweight construction and allows the load characteristic of the crossbeam to be functionally adapted to different requirements depending on the vehicle or vehicle class.
