<p>The present invention relates to a structural beam or bumper, especially for a vehicle, comprising an elongated profile which upon collision is adapted for absorbing collision energy and forces, the bumper being prepared from a complete and hollow blank and being further provided with different cross sections along its more or less arched extension, and 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, it is suggested that the bumper (1), has a substantially unchanged basic cross section (2) at each side of the centre (V-V), an outwardly pressed cross section (3) at the centre (V-V) in relation to said basic cross section (2), as well as a compressed or folded cross section (4) at the areas of each terminal portion.</p> |
