Abstract: 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).

In the method for manufacturing the bumper bar, the at least one part of the rear flange is wholly or partially pressed in towards the at least one part of the front flange.

Abstract: The invention concerns a method for manufacturing quenched metal hollow casings of steel by blow-moulding whereby a preheated hollow casing billet, preferably above austenitising temperature, is introduced into a blow-moulding tool (1) and moulded by being expanded against the inner walls of the tool by the introduction of a preheated, pressurized medium into the interior cavity of the hollow casing, whereby the moulded hollow casing (6) is rapidly cooled in a process adapted to obtain quenching of the steel material by the dominating heated medium in the hollow casing being replaced by a pressurized cooling medium and that a cooling medium is led through the moulding tool to achieve its cooling.

Abstract: In a method of manufacturing a curved and quenched profile element, a profile element is positioned in a die tool with relatively movable tool halves for forming the profile element into a desired curved shape. The profile element is pushed between the tool halves thereby heating the profile element to a quenching temperature and forming it into the desired curved shape. Heat is dissipated from the curved profile element at an elevated cooling device whereat a cooling liquid flows through the die tool while the profile element is still contained therewithin. The profile element is transported in a forward direction along a manufacturing path to the cooling device and is transported in the same forward direction to remove it from the cooling device thereby providing continuous mechanical handling of the profile element during the manufacturing process.
