A method for the individualized adaptation of the shape of components includes providing a basic material for producing the components. Next at least one unifying production method is selected. The components are then produced with a geometrically identical base shape by the unifying production method. Then at least one individualizing production method is selected. Then the shape of the components is adapted to at least two different final shapes by the individualizing production method that is different from the unifying production method. The final shape of each component differs from its basic shape.

A method may be used to produce a seamless pressure vessel for storing hydrogen. So that such a pressure vessel withstands both very high internal pressures and pressure fluctuations and (low) temperatures and temperature fluctuations and also high mechanical loading, is resistant to embrittlement, and is comparatively lightweight, a round or tubular workpiece may be formed that includes a multi-layer composite sheet metal material comprising a carrier layer made of steel material and a shielding layer resistant to hydrogen embrittlement by a flow forming process into a seamless hollow body, which serves as a semifinished product to be further processed into the seamless pressure vessel. The shielding layer may represent an inner layer of the pressure vessel. During the flow forming of the workpiece, the shielding layer may be retained as a whole-area, uninterrupted layer.

A connector is disclosed for providing a positive and/or a non-positive connection between at least two connecting partners. The connector or connecting means has at least one first region which engages with the first connecting partner by way of a positive and/or a non-positive connection, and at least one second region is provided which engages with the at least second connecting partner by way of a positive and/or a non-positive connection. The connecting means provides a positive and/or non-positive connection between at least two connecting partners in a simple and inexpensive manner and which meets high safety requirements. The second region of the connecting means has a region which is formed from an at least partially flat material made of an Fe alloy with shape memory characteristics and which, when activated, ensures the positive and/or non-positive connection with the second connecting partner by way of a change in shape.

Connection means with shape memory

A method is provided for producing a support structure, preferably a support structure for a vehicle seat having at least one seat shell for the seat part and/or the backrest of the vehicle seat, having the following method steps of producing a metal semi-finished product and reshaping it into an essentially flat plate, detaching a plate part from the plate, and deforming the plate part, the production of the metal semi-finished product being performed by extrusion. The semi-finished product may be already formed into a flat plate by the extrusion or the extrusion is performed with production of a curved plate, which is subsequently reshaped into a flat plate.
