Abstract
A bumper beam is roll formed so that it gets a closed cross section with, along the length, constant cross section having at least two closed chambers () separated by an essentially horizontal partition wall (). Each chamber has a side (), which is turned away from the vehicle, with at least one longitudinal concave portion () extending along the entire length and one side (), which is facing the vehicle, with at least one longitudinal convex portion () extending along the entire length. After the roll forming, some portions () of the cross section are pressed together vertically or horizontally in order to adapt the deformation properties.
