摘要:
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.

A side impact beam to be integrated in a motor vehicle includes at least one elongated bar, which has a trapezoidal cross section and terminates on both ends in ramp-like end portions, wherein the elongated bar has a central web, flanks diverging outwardly from the central web, and flanges connected to the extremities of the flanks, and terminal attachment zones. For manufacturing such a side impact beam, a semifinished flat blank is cut to size of constant width from a sheet metal material band of constant thickness and includes an elongated center portion of constant width and a length which is at least half a length of the blank, wherein the center portion terminates on opposite ends in tongue-shaped end portions.

In a method of making a bumper structure of a motor vehicle, a blank of quenched and tempered steel is formed into a U-shaped bumper beam having a middle part and attachment parts which adjoin the middle part on opposite ends and define crash boxes. The middle part of the bumper beam is hardened either during or after the blank is formed into the bumper beam.

In a method of making a hardened sheet metal article, at least one pot-shaped depression is formed in a sheet metal blank. Thereafter, the sheet metal blank is hot formed in a press mold to a sheet metal article, and the sheet metal article is hardened. The press mold provides hereby a calibration of the depression to provide the final shape.

A B-column comprises a component of a car body for a motor vehicle. The B-column constitutes a longitudinal steel profile. The invention provides that the longitudinal profile has a first longitudinal portion comprised of a martensitic material structure and a strength of more than 1400 N/mm2 and has a second longitudinal portion of higher ductility with a predominantly ferritic-perlitic material structure and a strength of below 850 N/mm2. The lower longitudinal portion is wider then the upper longitudinal portion and has an elongation at rupture which is below 25%.

A bumper arrangement for a front end or a rear end of an automobile having a bumper cover enclosing the bumper arrangement has a transverse support having a first and a second end. First and second spacer consoles are connected to the first and second ends of the transverse support, respectively. First and second stop plates are connected to the first and second spacer consoles opposite the transverse support. The first and second stop plates secure the bumper arrangement to longitudinal support beams of the car body extending in the longitudinal direction of the automobile. A transverse beam is positioned below the transverse support in a mounted position of the bumper arrangement. Spacer stays connect the transverse beam to the stop plates and are positioned below the spacer consoles. The transverse support and/or the spacer consoles, at least over portions thereof, have two or more deformation areas arranged next to one another in the longitudinal direction of the automobile. These deformations areas have different force levels.

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.

摘要:
A door structure of a motor vehicle includes an inside door panel, and a single-piece reinforcement element which is disposed below a window parapet of the door structure and non-detachably secured to the inside door panel at a side distal to an outside door panel. The reinforcement element includes a wraparound frame having a top frame side extending along the window parapet, a bottom frame side extending along a lower edge of the door structure, a front frame side disposed in a hinge area between the top frame side and the bottom frame side, and a rear frame side disposed in a lock area between the top frame side and the bottom frame side, thereby defining an opening. Disposed in the opening and formed in one piece with the frame is an embossed door impact beam which extends from the front frame side to the rear frame side. The reinforcement element is made of high-strength hot formable steel defined by a tensile strength ranging from 1400 N/mm2 to 1600 N/mm2.
