Abstract

The invention relates to a reinforced section for a vehicle supporting frame, said section connecting two pillars (8) of the vehicle supporting frame, in particular the C-pillars or D-pillars at their bases in the form of a transversal wall, whose ends, which are configured as pillar connection zones (6a, 7a), extend onto the pillars (8) by means of rounded corner reinforcements (6, 7). The invention is characterised in that the reinforced section and the corner reinforcements (6, 7) are configured as a one-piece double shell consisting of two blanks (10) produced in an internal high-pressure forming process and welded together around their periphery.
