Title
(EN) Hydroformed space frame and rearward ring assembly therefor
Abstract
(EN)

A space frame for a motor vehicle having a pair of laterally spaced, longitudinally extending side rail structures, a pair of forward-most upright structures each being connected to a respective side rail structure, thereby forming a pair of A pillars, a pair of roof rail structures, a forward end of each roof rail structure being connected to an upper end of an associated A pillar, and a rearward ring assembly connected at upper portions thereof with the roof rail structures and at bottom portions thereof with the side rail structures. The rearward ring assembly having (a) a tubular hydroformed inverted U-shaped upper member having a cross portion and a pair of leg portions extending downwardly from opposite ends of the cross portion, (b) a pair of tubular hydroformed side members, and (c) a cross structure rigidly connected in ring-forming relation between the second ends of the side members.
