Vehicle body structure
A vehicle body structure includes a rear pillar assembly, an attachment panel and a reinforcement panel. The rear pillar assembly has an upper end, a lower end and a mid-section and partially defines a rear corner area of a passenger compartment. The rear pillar assembly includes an inner panel that has a first upright edge that at least partially defines one side of a rear window opening and a second upright edge that at least partially defines a door opening. The attachment panel is fixedly attached to the inner panel along the mid-section of the rear pillar assembly. The reinforcement panel overlays the inner panel and the attachment panel and has a curved portion that extends from the attachment panel along the inner panel and curves downward along the inner panel. The curved portion is welded to the mid-section of the inner panel.
