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