Bumper crossmember for a vehicle

A bumper crossmember for a vehicle, comprising:

• a crossmember with a longitudinal extent thereof configured to extend in a vehicle transverse direction and convexly curved in a direction facing away from the vehicle, the crossmember comprising a hat-shaped cross-sectional profile with an upper limb, a lower limb, and a web connecting the two limbs to form a crossmember cavity, wherein a flange is formed on each limb at an end thereof opposite the web, and each flange is angled towards an outside of the crossmember relative to a plane of the respective limb on which the flange is formed, wherein the flanges have, at least in some regions, a rebounding flange formed thereon extending over a portion of the respective limb, and wherein each end of the crossmember has a respective crash box attachment portion,
• wherein the crossmember has a greater depth adjacent the crash box attachment portions towards a center of the crossmember than in the crash box attachment portions, and wherein the crash box attachment portions transition into those having a greater depth with interposition of a deformation zone provided by a concave portion of the web in a direction of the crossmember cavity, thus reducing the depth of the crossmember compared to a course of the web without the concave structure, and wherein, in a region of the concave structure along the longitudinal extent of the crossmember, the rebounding flange has a greater flange height than adjacent portions of the rebounding flange due to a convex protrusion of the rebounding flange.
