The invention relates to a process for manufacturing of an elongated metal beam (1) used as a vehicle body component, wherein the finished metal beam (1) has a width and/or height varying in its lengthwise direction In this process in the course of a relative movement of a counter die (3) on the one hand and a profiling machine (7) with profiling means (7b) on the other hand a semi-shaped portion (2d) of a semi-finished metal beam (2) is profiled towards a contoured buttress face (6) of the counter die (3) which extends in the lengthwise direction of the metal beam (2). The contour of the buttress face (6) conforms to the shape of the finished metal beam. Apart from this general process a manufacturing stand allowing to work this process is disclosed as well.

Process for manufacturing of an elongated metal beam (3) used as a vehicle body component, wherein the metal beam (3) in its lengthwise direction finally has at least one segment (4) with a full cross section, followed by a tapering segment (5) with tapering of the cross section in one direction - the tapering direction - from the full cross section to a reduced cross section, followed by a segment (6) with reduced cross section. The process comprises the following manufacturing steps: Providing a planar strip of metal sheet material with a predetermined width and continuously feeding the planar strip to a roll forming station. In the roll forming station roll forming the planar strip into a shaped strip (7) with a closed cross section or an essentially U-shaped cross section. Thereafter forming the tapering segment (5) of the shaped strip (7) by progressively displacing at least one wall - the thrust wall (8) - of the shaped strip (7) in the tapering direction towards an opposite wall (9) or an opposite open side of the shaped strip (7). During roll forming of the planar strip to the shaped strip (7) at least one lengthwise extending bead (10) is roll formed into the one wall or the two opposite walls of the shaped strip (7) that extends or extend in the tapering direction - the bending wall or walls (11) -. Each bead (10) provides a predetermined bending area of the corresponding bending wall (11). Forming of the tapering segment (5) of the shaped strip (7) is done by progressively compressing the bead or beads (10) from a large cross section in the segment of the shaped strip (7) with the full cross section to a small cross section in the segment of the shaped strip (7) with reduced cross section whilst leaving the other areas of the bending wall or walls (11) essentially unaltered.

The invention relates to an infinitely variable door check, especially for a vehicle door, with a hinge 1 comprising a first hinge part 2 and a second hinge part 3 which are pivotal relative to each other about a pivot axis 4, 24. According to a first aspect of the invention, a compression unit is provided that comprises an elastically deformable material 12 which is elastically compressed during movement of the first hinge part 2 relative to the second hinge part 3. Further, according to a second aspect of the invention, a braking unit 28 is provided that applies a braking load for the pivot movement of the first hinge part 22 relative to the second hinge part 23, wherein a gear 27, 31 is provided that interacts with the hinge shaft 25 and the movement of which is controlled by the braking unit 28. These designs allow for a very compact design for an infinitely variable check for an automotive door.
摘要:
Gegenstand der Erfindung ist ein Aufprallquerträger für eine Kraftfahrzeugkarosserie, insbesondere Stoßfängerquerträger oder Seitenaufprallschutz, in Form eines langgestreckten, durchlaufenden, vorzugsweise leicht gebogen verlaufenden Hohlprofils (1), das eine Längsrichtung definiert. Dieser zeichnet sich durch eine besonders flexible Herstellungstechnik aus. Das wird dadurch erreicht, daß das Hohlprofil (1) aus zwei sich in Längsrichtung erstreckenden Teilprofilen (1a,b) besteht, die aufeinanderzu gerichtet miteinander zusammengefügt und fest miteinander verbunden sind, wobei eines des Teilprofile (1b) im Querschnitt im wesentlichen U-förmig und das andere Teilprofil (1a) U-förmig oder geschlossen ausgeführt ist, wobei die die Abmessungen quer zur Längsrichtung, also in Querrichtung, also die Breite (B) des Hohlprofils (1) definierenden Flächen (5, 6) von den Teilprofilen (1a; 1b) gebildet sind.

摘要:
A side impact protection beam for a motor vehicle door, which is designed as an elongated profiled element (2) defining a longitudinal direction and is configured as a rolled profile or roll-formed profile of flat-strip metal material. In this arrangement, as viewed in the transverse direction of the flat-strip material, a central section of the flat-strip material forms a rear wall (3) of the profiled element (2) and the two outer sections of the flat-strip material are bent back inwardly toward the central section so that they in each case form a virtually closed hollow-chamber profile (4). Further the edges (6) of the outer sections forming the hollow-chamber profiles (4) are at a small distance from the central section forming the rear wall (3) and are not welded or fixedly connected in some other way to said central section. The rear wall (3) is designed to be smoothly continuous and the outer sections forming the hollow-chamber profiles (4) are bent over at their edge region into the respective hollow chamber (5) so as to form a narrow edge strip (7) each.
