Abstract: A process for the production of an armoring component for motor vehicles, the process beginning with provision of an armoring element made of an armored steel. At least one region of a surface of the armoring element is then subjected to particle-impact treatment. Finally, a coating is applied to the particle-impact-treated surface of the armoring element, where the coating consists of a material that is softer than the armored steel.

Abstract: An armoring part for a vehicle includes a steel plate made of at least partially hot formed and press hardened armor steel and having a hardness of 380 to 760 Vickers (HV). Applied on at least one side of the steel plate is a coat which is made of a metal material which is softer than a metal material of the armor steel. The coat is a thermally applied layer and has a hardness of 10 to 230 Vickers (HV).

Abstract: A three-dimensional structure for armoring a motor vehicle is made of a steel plate and has a substantial hemispherical shape. The structure is reinforced by bending edges having an X-shaped configuration extending over the entire surface of the structure. Arranged between the legs of the X-shaped portion are sections which have surface areas between the legs of the X-shaped portion. The surface area of the X-shaped portion has a generally concave curvature, whereas the surface areas of the sections 11 have convex configurations in relation to the concave surface area of the X-shaped portion.

Abstract: In a method for producing an outer wall, in particular a side wall for a motor vehicle, from armored steel, having openings, a rocker panel extending in the bottom region, a roof frame area, pillars and side pieces extending between the rocker panel and the roof frame area, and openings for receiving windows, the outer contour of the outer wall is defined, and a pressing tool is provided for forming an outer wall blank having this outer contour. The outer wall blank is formed from an armor steel metal sheet and the doors and the openings are cut out from the outer wall blank.

Abstract: Apparatus for heat-treating an elongate structural body part made from a blank compressed while being soft or from steel strip of hardenable 22 Mn B5 mod. steel sheet with a thickness of 1 mm to 3 mm, includes an apparatus for positioning the structural body part in substantially upright disposition. Placed in surrounding relationship to the structural body part is an induction element which can move from bottom to top, thereby being able to follow a contour of the structural body part and allowing to at least partially heat the structural body part to an austenitizing temperature suitable for hardening. Disposed adjacent to the induction element is a cooling unit which follows the induction element in movement direction. The induction element and the cooling unit are moveable relative to one another and connected to a tool carriage which is mounted to a column for movement in a vertical direction, in a transverse direction to the column and about a horizontal axis.

Abstract: A safety arrangement for a motor vehicle, includes at least one airbag disposed in a roof frame of a vehicle body. A pressure gas source, positioned remote to the airbag, is fluidly connected with the airbag by a connection line for supply of a pressure gas to the airbag and inflation thereof. The connection line is formed by a hollow space of the roof frame or the roof frame itself, whereby the roof frame and/or the hollow space is formed by metal sheets connected to one another in a fluid-tight manner by an adhesive joint.

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. The press mold provides hereby a calibration of the depression to provide the final shape.

Abstract: In a method of making a steel crossbeam for use as component of a bumper for motor vehicles, a composite element is formed by attaching sheet metal strips in parallel disposition onto a broadside of a steel sheet strand across an entire length thereof, whereby the sheet metal strips have a width which is narrower than a width of the steel sheet strand. The composite element is then shaped through roll-forming in a direction transverse to the longitudinal extent of the composite element into a crossbeam.

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.
