The present application relates to a reinforcement element () arranged to be attached to a profile () for forming a B-pillar for a vehicle, which profile () is arranged with attachment areas () for door hinges, characterised in that the reinforcement element () is designed with two elongated strips () of material, wherein the strips () are inter-connected at least at one attachment area () for door hinges when the reinforcement element () is attached to profile (), wherein the profile () is hat-shaped with a central flange () and two sides (), and wherein each strip () is attached to the transition area () between the central flange () and a side (). The present application alsorelates to a B-pillar provided with the reinforcement element as well as a method of manufacturing a B-pillar with the reinforcement element.

Corner patch

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 ().

B-pillar for a vehicle

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