Abstract: A mechanism for increasing stiffness of the side-structure of a vehicle, for transferring loads and strain energy, and for improving rigidity from the lower portion of a side pillar, to the underbody structural components of the vehicle. The vehicle includes a hydroformed tube having a horizontal portion, a vertical portion and an arcuate central portion. The upper end of the vertical portion is spot welded to the lower portion of the side pillar. The horizontal portion is received into, and spot welded to, an inner portion of a structural member. The structural member is an L-shaped bracket, and its major portion is spot welded to an inner portion of an elongated beam. The beam is fixedly attached to the side rail of the vehicle. The tubular member, the structural member, and the elongated beam, when connected, form a closed continuous box shaped structure, which reinforces the side-structure of the vehicle.

Abstract: A wheelhouse reinforcement bracket provides increased torsional rigidity for the rear wheelhouses of an automotive vehicle. The wheelhouse bracket is positioned in alignment with the location on the vehicle body where the shock absorber is located, and in alignment with the rear suspension cross frame member to create a structural ring formed by the wheelhouse bracket, the C-pillar and the rear suspension cross frame member. The wheelhouse bracket is formed with a mounting flange positionable within the inside of the U-shaped rear side frame rail to facilitate welding thereto instead of being welded to the top of the underbody floor structure. The mounting flange has a first portion configured to be mated against a first generally vertically extending wall of the rear side frame rail and a second portion configured to be mated against a generally horizontally extending wall of the rear side frame rail.
