    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.

    Abstract translation: 车体屋顶结构包括大体上共同延伸的内外屋顶板。 外板的纵向边缘在内板的相似边缘上下摆边缘。 面板的侧边缘设置有彼此焊接的配合夹持法兰。 内板的中心部分紧邻外板的相似部分并通过多个胶粘剂固定在其上。 限定内板的中心部分和外板的相似部分的横向和纵向边缘部分提供侧轨和集管结构。 这些边缘部分比中心部分间隔开更大的距离。 内板设置有纵向间隔开的一排横向对齐的开口，用于接收列表线安装夹。 某些开口和前侧边​​缘部分设置有向外压花的坝，以在装配后在所得结构的运输期间限制未固化的粘合剂相对于这种开口和边缘部分的流动。 内板还设有穿孔以允许在内板和外板之间的空间中的吸声。 一个或多个压纹肋可以设置在内板中，并且内板的中心压花支撑着与外板接合的吸声垫。
