Vehicle body roof structure
Abstract:
A vehicle body roof structure includes inner and outer roof panels generally coextensive in size. The longitudinal edges of the outer panel are hem flanged over like edges of the inner panel. The lateral edges of the panels are provided with mating pinchweld flanges welded to each other. The central portion of the inner panel is located immediately adjacent a like portion of the outer panel and secured thereto by a plurality of adhesive drops. The lateral and longitudinal marginal portions bounding the central portion of the inner panel and like portions of the outer panel provide the side rail and header structures. Such marginal portions are spaced a greater distance from each other than are the central portions. The inner panel is provided with longitudinally spaced rows of laterally aligned openings for receiving listing wire mounting clips. Certain of the openings and the front lateral marginal portion are provided with outwardly embossed dams to limit flow of the uncured adhesive with respect to such openings and marginal portion during shipment of the resultant structure after assembly. The inner panel is further provided with perforations to allow for sound absorption in the space between the inner and outer panels. One or more embossed ribs may be provided in the inner panel, and a center embossment of the inner panel supports a pad of sound absorbing material in engagement with the outer panel.
