Abstract: A structural motor-vehicle element is made by hot-shaping and press-hardening a steel workpiece into the element and thereafter heating the hot-shaped and press-hardened workpiece to between 320° C. and 400° C. The steel workpiece constitutes in weight percent, Carbon (C) 0.18% to 0.3% Silicon (Si) 0.1% to 0.7% Manganese (Mn) 1.0% to 2.5% Phosphorus (P) max. 0.025% Chromium (Cr) up to 0.8% Molybdenum (Mo) up to 0.5% Sulfur (S) max. 0.01% Titanium (Ti) 0.02% to 0.05% Boron (B) 0.002% to 0.005% Aluminum (Al) 0.01% to 0.06% the rest iron including impurities caused by the smelting process.

Abstract: 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.

Abstract: A B column of a motor vehicle having a high strength and rigidity in the attachment area of door hinges and door locks and able to protect the occupants of the vehicle in the event of a side crash is provided. The B column includes a reinforcement plate, which extends over the entire height of the B column. Because the requirements for this reinforcement plate are not equally great in all areas, the reinforcement plate is a reshaped tailored rolled blank. The tailored rolled blank is produced by flexible rolling and has different thicknesses transversely to the rolling direction. It is thus especially thick in the areas on which especially high strength and rigidity requirements are placed, while it is implemented as correspondingly thin in the areas which must only fulfill low strength and rigidity requirements.

Abstract: 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.

Abstract: A side impact beam for incorporation into the structure of a motor vehicle comprises a sheet metal profile with flaring end portions and two longitudinal beads extending along the sheet metal profile and wherein the end portions that are provided with cross beads that are stamped in an additional tooling step during manufacturing and after the longitudinal beads have been formed, and are arranged in transverse disposition to the longitudinal beads and wherein the longitudinal beads and the cross beads are oriented in the same direction and the length of one cross bead corresponds approximately to the width of the two longitudinal beads, such that the so configured cross beads provide a stabilizing effect of the end portions and ensure the flattening of the connecting surfaces, thereby leading to a reduction of assembly problems.

Abstract: A workpiece having regions of different ductility is made by first coating opposite faces of a flat sheet-metal workpiece of low ductility and then stripping the coating from the faces in one region of the workpiece while leaving the coating on the faces in another region of the workpiece. The workpiece is then deformed into a three-dimensional profile. Only the one uncoated region of the workpiece is heated and thereby hardened while not significantly heating the other coated region of the workpiece.

Abstract: 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.

Abstract: A side impact beam for incorporation in a motor vehicle, in particular in a vehicle door, includes a profiled section of sheet metal having at least two longitudinal beads in side-by-side disposition. Each bead has an apex and two flanks depending from the apex, thereby defining an inner flank and an outer flank, wherein the inner flanks of the beads confront one another. The inner flanks are interconnected by a center web and are disposed in V-shaped relationship at an angle from 25° to 60°.

Abstract: 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.

Secured to the attachment element is a blocking element which at least partially bridges a spacing between the outer shell and the inner door panel to thereby prevent access to the actuating mechanism of the door lock via a gap in the outer shell.

Abstract: In a method of making a structural member for the automobile industry, a blank of boron steel is pre-formed at ambient temperature into an intermediary part of a configuration which substantially corresponds to an end shape of a finished structural member. The intermediary part is then coated with aluminum or an aluminum alloy and exposed to a temperature above the upper transformation line in the TTT curve. Subsequently, the intermediary part is formed in a mold into the finished structural member while being hardened at the same time.
