Claim 11:
12. A method of producing a shaped structure support for a vehicle, comprising:
providing a hollow workpiece of a boron steel material with a circular cylindrical shape;
heating the hollow workpiece to a material transformation range to provide the boron steel material with an austenitic microstructure;
forming the hollow workpiece into the shaped structure support having a predefined complex geometry by deforming the hollow workpiece in a press while the hollow workpiece is still in the material transformation temperature range;
quenching the hollow workpiece in the press to provide the shaped structure support with a martensitic microstructure;
wherein forming the hollow workpiece and quenching the hollow workpiece are performed in the same step where the hollow workpiece is pressed and held in a closed die set between a first die and a second die of the press.
