Abstract

2015 Invention Summary Revised 20/10/2015 The objective is to reinforce both the hinge attachment shoulder portion in the top portion of the opening section for securing the rear door and the top corner portion of the opening section by means of a simple and lightweight construction. A closed sectional structure (21) is formed by the roof panel and the rear interior member of the roof and is connected to the side bodies in the top corner portion (3) of the opening section. The reinforcement bar (13) extends rigidly from the hinge attachment shoulder (8) to the side bodies (7) between the roof panel (4) and the rear interior member of the roof (12), and is connected to the hinge attachment shoulder (8) and the vertical wall (9) formed in the rear portion of the roof panel. The reinforcement bar (13) has a crank shape in cross-section and has a mountain crease line on the top (20L) and a valley crease line on the bottom (19L). The distance (H) between the top and bottom ridges is small around the hinge attachment shoulder portion in the vehicle width direction and large around the section. Outside in the vehicle width direction of the side body -------------------------------------------------------------- The object of the present invention is to reinforce the hinge mounting shoulder for the top portion of the rear door attachment opening section and the top corner portion of the opening section at the same time by using a simple and light weight structure. A closed cross-sectional structure (21) is formed by the roof panel and the rear interior member of the roof. The closed cross-sectional structure is connected to the side body by the top corner portion (3) of the opening section. Reinforcement bars (13) are arranged and fastened from the hinge mounting shoulder (8) across to the side body (7). Between the roof panel (4) and the rear interior member, the roof (12) and the reinforcement (13) are connected to the vertical wall (9) formed in the rear portion of the roof panel and to the hinge mounting shoulder (8). The reinforcement (13) is shaped so as to form a crank-shaped cross-section such that there is a ridge-shaped fold line (20L) on its top and a valley-shaped fold line (19L) on its bottom, and such that there is a distance (H) between the top and bottom ridge lines. Narrows in the vicinity of the inner hinge mounting shoulder in the vehicle width direction and widens in the vicinity of the outer side body in the vehicle width direction.
