A vehicle is subjected to many requirements and wishes. One of these is that the vehicle is to protect passengers and load during a collision. This is achieved in that different parts in and on the vehicle are designed and constructed such that they, in different ways, absorb, distribute and channel energy during a collision. A bumper bar for a vehicle must be deformed both elastically and/or plastically during a collision. This invention offers a bumper bar that in its basic construction provides these properties. The invention concerns a bumper bar for vehicles where the bar is extended and has a closed cross-section with at least one forward flange (1) facing forwards in the normal direction of motion of the vehicle, an upper web (3) and a lower web (4). The forward flange (1) of the bumper bar is provided with elastically deformable grooves (6). |
