- the hook-shaped hollow structure preferably has one, up to a Falzflansch outer edge expanding Vergargungs-cross section on. In this way, a stamping contour can be realized directly in the rabbet flange outer edge, which can be brought into engagement with the inner sheet metal part embossment.
- the hook-shaped hollow structure can have two closed-surface side flanks formed in the sheet-metal base section. These converge on a central floor land and go on lateral edges in the sheet metal base section of the
- the bottom web of the hook-shaped hollow structure may extend at right angles to the seam flange outer edge with regard to increased component rigidity.
- hook-shaped hollow structure converge at apex and merge into the sheet metal base portion of the outer sheet metal folding flange.

- This passes via a laterally circumferential material web 19 in the inner sheet metal part base portion 15 via.
- the material web 19 has a material thickness Si in FIG. 3, which is greatly reduced in comparison to the material thickness S2, S3 in the inner sheet metal part base section 15 and in the embossment bottom 17, as a result of which the embossment geometry stiffness is reduced.
