Abstract:
The invention relates to a B-pillar for a vehicle including a main section (20) with a hat-shaped section (21) comprising a central flange (22), two web portions (23, 24) and two side flanges (25, 26). At least the hat-shaped section (21) is press-hardened and has a breaking strength in excess of 1400 MPa and the side flanges (25, 26) of the hat-shaped section (21) have a breaking strength below 1100 MPa along at least part of the length of the side flanges (25, 26). The B-pillar (13) includes a cover plate (40) welded to the side flanges (25, 26) of the hat-shaped section (21) so as to form a closed profile, the cover plate (40) having a breaking strength below 1100 MPa at least in the region in which it bears against the side flanges (25, 26). The side flanges (25, 26) of the hat-shaped section have a breaking strength below 1100 MPa in the region in which the side flanges bear against the cover plate (40).
