Abstract: A method for the roll-forming of profiles or structural parts from semifinished sheet-like products, in particular from metallic materials, in particular from steel sheet or aluminum. For this, the semifinished sheet-like product is adjusted in its temperature, the adjustment of the temperature taking place locally, in particular in forming regions of the semifinished product that are intended to undergo a forming operation. Furthermore, a component is preferably produced by using this method, in particular a structural part for a seat structure of a motor vehicle, in particular a vehicle seat rail that can be adjusted forwards and backwards to adjust the seat, and to a roll-forming device for carrying out the method.

Abstract: The present invention relates to a method for producing a component of an adjustment device for vehicle seats, wherein, in a first step, a work piece is machined such that the work piece is harder in a first region than in a second region, and/or in that the work piece is of a larger geometrical size in a third region than in a fourth region, wherein, in a second step, the work piece is deformed in such a way that a tool is moved onto the work piece at a speed greater than 1 m/s.

Abstract: A longitudinal adjustment device for a vehicle seat includes at least one rail guide with at least one upper rail and a lower rail, wherein the upper rail and lower rail are mounted movably relative to each other via a bearing. A roller cage is provided as the bearing between the upper rail and lower rail, wherein, in the roller cage, rollers are arranged inclined at a predetermined angle with respect to the horizontal plane of the rails or transversely with respect to the running direction of the rails.

Abstract: A head restraint for a vehicle seat includes a first subsection facing the occupant's head, and is displaceable due to application of a predetermined force. A third subsection includes a central hub portion that supports the second subsection. The second subsection is arranged between the first subsection and a third subsection, and is mounted to the central hub portion of the third section and the first second and third subsections are rotatably displaceable about an axis of rotation that is parallel to the direction of displacement (C). A blocking device includes a toothed portion complimentarily engaged with a spacer device on the third subsection and having a resilient member preventing engagement of the toothed portion by the spacer device when the first subsection is not subjected to the application of the predetermined force, and also controls movement of the first subsection counter to a direction of displacement.
