Abstract: The invention relates to a method for producing a torsional profile from a blank. The torsional profile has torsionally rigid tubular end sections, a torsionally flexible U-shaped middle longitudinal section and, between the middle longitudinal section and the end sections, transition sections which change from the U-shaped cross section to the tubular cross section.

Abstract: A window and/or roof frame for an automobile, which has at least two bows running transversely to a direction of travel and at least two longitudinal members, wherein the window and/or roof frame is produced as a one-piece sheet metal formed component from a single blank in one press stroke. Different wall thicknesses and/or strengths are formed locally, wherein the wall thicknesses or tensile strengths differ by at least 10%.
