Title
(EN) Bumper, and the fabrication thereof
Abstract
(EN)

A structural beam or bumper, especially for a vehicle, including en elongated profile which upon collision is adapted for absorbing collision energy and forces. The bumper is prepared from a complete and hollow blank and is further provided with different cross sections along its more or less arched extension. Also, for the purpose of providing a structural beam or bumper bar which renders possibilities for rational and structural sturdy attachment to the frame of the vehicle, the bumper (1), has a substantially unchanged basic cross section (2) at each side of the center (V--V), an outwardly pressed cross section (3) at the center (V--V) in relation to the basic cross section (2), as well as a compressed or folded cross section (4) at the areas of each terminal portion.
