Abstract

A space frame includes a pair of laterally spaced, longitudinally extending side rail structures and longitudinally spaced pairs of laterally spaced upright structures having joints at their lower ends with the pair of side rail structures. The longitudinal spaced pairs of laterally spaced upright structures extend upwardly from the side rails structures and define a plurality of pairs of pillars, including a pair of forward A pillars, a longitudinally spaced pair of B pillars, and a longitudinally spaced pair of rearward end pillars. A pair of the side roof structures has joints with the pair of A pillars. The pair of side roof structures extends longitudinally rearwardly from the pair of A pillars and have joints with the pair of B pillars and with the pair of rearward end pillars. Longitudinally spaced cross structures have joints with the pair of side rail structures, with the pair of A pillars and with the pair of side roof structures. A front structural assembly has joints with a forward end of the pair of side rail structures and with the A pillars at positions spaced upwardly of the pair of side rail structures. A plurality of the structures have more than two spaced successive joints which determine defining lengths in the space frame. The plurality of structures comprise a pair of hydroformed tubular members, each of which is defined by an irregularly outwardly deformed tubular metallic wall fixed into a predetermined irregular exterior surface configuration.
