Abstract: A side impact beam for motor vehicles has a profiled section of sheet metal having a length in a longitudinal direction and having a cross-sectional shape over most of the length. The cross-sectional shape has at least one cross-sectional portion comprised of a stay extending in the longitudinal direction, a first leg and a second leg connected to opposite longitudinal sides of the stay, a first flange connected to a free end of the first leg, and a second flange connected to a free end of the second flange. At least one tension element connects the first and second legs.

Abstract: In a method of forming a hollow workpiece having open ends by inner pressure in a multi-part forming tool, the forming tool having a forming mold is heated and the workpiece is placed into the forming mold of the forming tool. Closing plugs are inserted into the open ends of the workpiece, wherein the closing plugs are components of closing cylinders, in order to seal off the open ends. The forming tool is closed. A heated pressure fluid is introduced into the hollow workpiece through at least one of the closing plugs, with the hollow workpiece having been heated and plasticized in the forming tool. The material of the hollow workpiece is pressed with the heated pressure fluid into the forming mold of the forming tool. The device for performing the method has a multi-part forming tool with a forming mold for the workpiece. Hydraulic closing cylinders with closing plugs are provided for sealing the open ends of the workpiece. The forming tool has a heating device for heating at least the forming mold.

Abstract: A door frame for motor vehicles includes a window channel laterally defined by an outer door panel and an inner door panel, wherein the outer door panel and the inner door panel are provided adjacent of the window opening with longitudinally extending stiffening or reinforcement members located in the window channel. The reinforcement members are circumferentially closed tubular sections having an essentially oval cross-section, wherein the reinforcement members are adapted in their shape to the inner surfaces of the outer door panel and the inner door panel.

Abstract: A fuel supply system for automobiles with a fuel tank to which are connected a filler pipe and at least one vent for venting the tank during operation of the automobile and one vent for venting the tank during refueling of the tank. The operation vent line and/or the refueling vent line are components of a multiple-duct line. The filler pipe may also be incorporated in the multiple-duct line.

Abstract: A steel alloy for pipes, sheet metal or sections for manufacturing body reinforcements for motor vehicles, particularly side impact beams or A- and B-column reinforcements, wherein the steel alloy contains in percent by weight 0.1 to 0.17% carbon, 2.0 to 2.8% manganese, 0.4 to 0.8% chromium, 0.1 to 0.35% molybdenum, 0.03 to 0.07% aluminum, 0.002 to 0.003% boron, 0.0001 to 0.005% titanium, 0.08 to 0.012% vanadium, 0.025 to 0.06% niobium, 0.0001 to 0.10 zirconium, 0.01 to 0.05% nitrogen, up to 0.3% silicon, up to 0.025% phosphorus and % 0.010 sulfur, wherein the remainder is iron including impurities caused by smelting, and wherein the sum of the alloy components titanium, vanadium and niobium is between 0.16 and 0.25%.

Abstract: A side impact beam for a passenger vehicle, particularly for a vehicle door, includes a hat-shaped profiled section which is open toward the external panelling of the passenger vehicle and has at least one web facing away from the external panelling, two legs connected to the web and directed toward the external panelling and two flanges connected to the ends of the legs and facing away from each other, wherein, starting from the transverse plane in the middle of the beam, the height of the profiled section decreases continuously toward the ends of the beam provided with increased width flanges serving for securing the beam to the vehicle chassis. The height of the profiled section may decrease in accordance with a uniform or non-uniform curve pattern.

Abstract: The tubular reinforcement member (2) has a circular cross section. Compared to the end portions serving for fastening the reinforcement member to the inner side of the door, the middle portion (1) in longitudinal direction of the reinforcement member has a greater resistance against bending loads. For this purpose, at least one sheet steel strip (4) extending parallel to the longitudinal axis (3) of the reinforcement member is tangentially fastened to the periphery of the middle portion (1) in a plane extending parallel to the impact direction (5). The width (B) of the sheet steel strip (4) is overall smaller than the thickness (D) of the reinforcement member. The width (B) decreases in accordance with the bending moment pattern toward the ends of the sheet steel strip (4). The decrease in width may be linear or parabolical.

Abstract: A die (2) formed of two halves (4, 5) is placed in a container (7) filled with an incompressible liquid. The die halves have a plane of contact disposed in parallel relation with and spaced from the axis of a hollow member to be deformed within a die cavity formed by the die halves. Mandrils (15) are forced into sealing contact with the open ends of the hollow member by hydraulic cylinders. A high deformation pressure is supplied into the hollow member and the mandrils are secured in sealing contact with the hollow member against such pressure.
