Abstract

A one-piece B-pillar having a front flange and a rear flange formed on an upper portion of the B-pillar. The front and rear flanges extend forwardly and rearwardly from a trapezoidal section of the B-pillar. An inner concave portion is provided in a lower portion of the B-pillar. The one-piece B-pillar is secured to the outer and upper surfaces of a roof rail and to the outer surface of a rocker to provide side impact strength. The B-pillar is hydroformed in one-piece to provide superior strength for roof crush performance. The tubular portion of the B-pillar is partially collapsed to form a trapezoidal section in the upper portion of the B-pillar.
