Abstract
A body side construction for an automotive vehicle is formed from multiple tubular members arranged to maximize the strength of the body side members while minimizing the amount of material utilized in the manufacture of the body side members and, thus reducing the cost of manufacture of the automobile. The body side members are formed from tubular members preferably manufactured through a hydroforming process. The tubular members extend from the front pillar to the rear pillar and can vary in number and in size as appropriate for the load being carried by the body side members. The tubular members can also be used to transition from the body side portion of the automobile to the roof structure to provide an integrated frame assembly. The formation of the body side members from multiple tubular members also creates an internal reinforcement web to further enhance the strength of the section.
