Abstract

The invention relates to a B-pillar reinforcement of a motor vehicle having an upper region for joining the B-pillar reinforcement to the roof region of the motor vehicle and a lower region for joining the B-pillar reinforcement to a floor support of the motor vehicle, which B-pillar reinforcement comprises at least one hollow profile made of metal, in particular steel, and the hollow profile forms the upper and lower regions of the B-pillar reinforcement. The object of providing an improved B-pillar reinforcement which, on the one hand, is optimised in respect of a load-appropriate configuration with a minimum weight, allows a very good integration of additional components of the B-pillar, is achieved in that the hollow profile has at least to some extent a substantially trapezoidal cross-sectional surface in one of the regions and has an at least partly U-shaped cross-sectional surface in the other region.
