A bumper beam is made of at least one rolled formed steel sheet containing an upper beam and a lower beam extending in a transversal direction, the upper beam and the lower beam each having a closed cross-section defined by a front wall, a rear wall, an upper wall and a lower wall, the upper wall and the lower wall joining the front wall to the rear wall, each of the front walls of the upper beam and of the lower beam containing a front rib extending transversally and towards the interior of the bumper beam. At least one of the upper wall of the upper beam, the lower wall of the lower beam, the rear wall of the upper beam and the rear wall of the lower beam further containing a rib extending transversally and towards the interior of the bumper beam.

Bumper beam having ribs on several walls of the bumper beam

A bumper beam made of at least one roll formed steel sheet is described. The bumper beam contains an upper beam and a lower beam extending in a transversal direction, the upper beam and the lower beam each having a closed cross-section defined by a front wall, a rear wall, an upper wall and a lower wall, the upper wall and the lower wall joining the front wall to the rear wall, and a central wall extending between the front walls, the rear walls of the upper beam and of the lower beam forming both the lower wall of the upper beam and the upper wall of the lower beam, the central wall extending in at least two different planes.
