Cross member behind outer skin of bumper of motor vehicle has plastically deformable profile with upper and lower surfaces each having on end of cross member at least one cut-out located perpendicularly to direction of impact force

摘要

The cross member (1) for a motor vehicle is polygonal in cross section and constructed as a stable but plastically deformable profile (2) with an upper (12) and a lower (13) surface which yield above a predetermined load during an impact-like force action. The upper and lower surfaces of the profile each have on the end of the cross member at least one cut-out (3) located perpendicularly to the direction of force. The cut-outs are located close to the impact surface (14) of the profile.
