摘要:
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.

The invention relates to a structural element (100) of a motor vehicle, in particular of a motor vehicle seat, wherein the structural element (100) comprises a first component (101) and a second component (102). In an overlap region (103), the first component (101) and the second component (102) have a form-closed connection, or a form-closed and force-closed connection, wherein the connection in the overlap region (103) can be produced by an electromagnetic pulse shaping method, wherein the first component comprises at least one form-closed moulding (600), wherein the second component can be moulded into the at least one form-closed moulding (600).

The invention relates to vehicle seat comprising a seat part and to a restraint device and a corresponding method of manufacture. The vehicle seat comprises an anti-submarining restraint device for preventing an occupant from slipping through on the vehicle seat when decelerated due to a crash, said restraint device being settable to a retracted inactive position and said restraint device being settable to an extended active position. The seat part, in the longitudinal direction of the vehicle, has lateral seat parts on both sides of the seat, a padding defining a seat area and a padding support (34) below said padding. The restraint device also comprises a tilting element (24) between the padding support and the padding and spaced apart from the lateral parts, said tilting element having at least one deformable element (24) as an energy dissipation element.

The invention relates to a method for joining at least two workpiece layers (1, 2) by introducing a connecting element (10) with a coating (15) applied externally to the connecting element (10), wherein the connecting element (10) is guided, in particular punched, through the first workpiece layer (1) by means of a ram (26), forming a cut surface (1), and penetrates at least partially into the second workpiece layer and is deformed by means of a die (21) such that it connects the at least two workpiece layers (1, 2) together in a form-fitting manner. The connecting element (10) is heated such that the coating (15) applied externally to the connecting element (10) melts and wets, in particular completely closes, the cut surface in the first workpiece layer (1); after a cooling process, the re-solidified coating (15) adheres to the cut surface of the first workpiece layer (1).
