In a method of making a steel crossbeam for use as component of a bumper for motor vehicles, a composite element is formed by attaching sheet metal strips in parallel disposition onto a broadside of a steel sheet strand across an entire length thereof, whereby the sheet metal strips have a width which is narrower than a width of the steel sheet strand. The composite element is then shaped through roll-forming in a direction transverse to the longitudinal extent of the composite element into a crossbeam.

Method of making a steel crossbeam which crossbeam forms a component of a bumper for motor vehicles, and crossbeam

A bumper for a motor vehicle has a transverse support and impact damping members connected to the transverse support, wherein the transverse support is fastened transverse to longitudinal supports of a motor vehicle frame via the impact damping members to the longitudinal supports. The transverse support is an open profiled member opening in a direction toward the impact damping members and has an upper shell and a lower shell. The transverse support has a front stay with an upper longitudinal edge and a lower longitudinal edge, wherein each one of the upper and the lower longitudinal edges has a leg extending toward the impact damping members. Each leg has a vertical portion and an angled reinforcement flange pointing toward the vehicle frame. Each leg is slanted inwardly between 5 degrees and 45 degrees from the longitudinal edges to the vertical portions.
