Bow-formed bumper beam for vehicle, has hat profile with central flange, two webs and side flanges, where flanges have bent edges in area between fastening areas, and bent edges have transverse dents at beginning of bent edges

摘要

The beam has a hat profile with a central flange, two webs and side flanges. The webs and the flanges form a crown of the hat profile. The central portion of the central flange has an elongate stiffener in a depression form. The webs are convex to control the deformation. Fastening portions of the beam are at the sides. The side flanges form fastening areas and have holes for fastening the beam to the vehicle with the central flange facing outwards. The side flanges have bent edges (26) in the area between the fastening areas, where the bent edges have transverse dents (29) at the beginning.
