An A-pillar for a vehicle includes a first part (15) extending as far as the windscreen and supporting the door hinges and a second arcuate part (16) extending up along the windscreen and continuing towards the back in order to serve as a roof beam (19) above the door. This second part consists of two open sections (23, 24) with flanges (25, 26; 27, 28) welded together so as to give the pillar a closed profile. At least one of the sections (23) is press-hardened and has a breaking strength in excess of 1400 MPa and the flanges (25, 26; 27, 28) of the sections have a breaking strength below 1100 MPa in a portion (35) situated above the door. |
