Body structure of a motor vehicle

A vehicle body structure of a vehicle comprising:

• a pair of body side frame assemblies extending longitudinally on the vehicle and precisely spaced from each other, and each having a lower horizontal surface projecting outboard;
• and
• an underbody sub-assembly transversing the vehicle and having a generally planar floor pan including a pair of longitudinal edges and a horizontal surface adjacent each of the longitudinal edges and each of the horizontal surfaces of the floor pan underlying and engaging one of the lower horizontal surfaces of the body side frame assemblies;
• and weld means attaching the horizontal surfaces of the floor pan to the lower horizontal surfaces projecting outboard of the body side frame assemblies subsequent to adjusting the underbody sub-assembly transversely relative to the body side frame assemblies.

A vehicle body structure of a vehicle comprising:

• (a) a pair of body side frame sub-assemblies running longitudinally on the vehicle and each including;
• (i) a body side outer panel having an appearance portion extending vertically and longitudinally, outboard projecting horizontal flange extending longitudinally and projecting outboard, and a forward generally vertical outboard projecting flange,
• (ii) a rocker inner frame extending longitudinally having an inboard vertical wall spaced inboard from the body side outer panel and a lower horizontal wall projecting outboard having an extreme outboard portion underlying the lower horizontal flange of the body side outer panel,
• (iii) an inverted "U" shaped cross member extension secured to the inboard vertical wall of the rocker inner frame and projecting transversely inboard
• (b) an underbody sub-assembly for extending transversely across the vehicle and including
• (i) a generally planar floor pan having a pair of outboard longitudinal edges and a horizontal surface adjacent each of the longitudinal edges and underlying and engaging the lower horizontal wall of the rocker inner frame of one of the body side frame sub-assemblies,
• (ii) an inverted "U" shaped cross member extending transversely and overlying and secured to the floor pan and having a pair of ends, each end underlying one of the cross member extensions and the horizontal surface of the floor pan secures to the extreme outboard portion and the cross member secures to the cross member extension subsequent to the underbody sub-assembly adjusted transversely relative to the body side frame sub-assemblies, and
• (iii) a dash panel having a horizontal portion including a lip securing to the floor pan and the dash panel having a generally vertical firewall portion flexed and conformed to the forward vertical flange of the body side outer panel of the body side frame sub-assemblies.
