In the above-mentioned welding process of the seat back frame, it is general to perform CO 2 welding or spot welding while securing the dimensional accuracy by positioning each member with a dedicated jig. It is. At that time, in order to accurately obtain the shape of the seat back frame 50, for example,
A side frame 52 for the upper frame 51,
The position 53 and the mounting angle R (see FIG. 12), the total width W of the left and right side frames 52 and 53 connected by the lower frame 54 (see FIG. 13), the mounting pitch and the mounting angle Q of the headrest bracket 55 with respect to the upper frame 51. (See FIG. 14). Therefore, in order to ensure the accuracy of the joint, the dedicated jig becomes larger, such as using a large air cylinder for the gripping mechanism.
The cost was high. In addition, since the upper frame 51 has a pipe structure, equipment for pipe processing is required, and the cost burden is large especially in the case of small-scale production.

Next, the headrest support mounting member 7 will be described. As shown in FIGS. 1 and 2, the headrest support mounting member 7 has a shape having flanges at both ends of the rectangular tube, and the upper frame member 2 and the upper frame member 2 are arranged such that the axis of the rectangular tube passes through the center of the through hole 2 a. It is arranged between the reinforcing members 6 and welded. Note that the headrest support mounting member 7 may be a rectangular tube having no flange or a cylindrical member. In this case, since the headrest support attachment member 7 also serves as a strength member connecting the upper frame member 2 and the upper reinforcing member 6, the rigidity of the seat back frame 1 can be increased and the headrest support can be firmly supported. By the way, welding of each part described above is fillet welding or plug welding by CO 2 welding, or
It shall be appropriately selected and applied from spot welding and other welding methods.

Further, since components (frame members) can be partially shared between seat frames of different types (dimensions), costs such as minimizing the number of parts and increasing the number of press dies are minimized. Down becomes possible. For example, when the height of the seat frame is raised, as shown in FIG. 6, the upper frame member 2 and the headrest support mounting member 7 are simply replaced with a tall upper frame member 2 'and a headrest support mounting member 7'. A seat back frame that is slightly taller than the seat back frame 1 can be manufactured by diverting other parts as they are. In addition, it is possible to cope with the case where the width of the seat frame is increased.

As described above, in the seat frame according to the present invention, the adjacent frame members are joined to each other at the fitting portions and then welded, so that the positioning jig at the time of welding can be simplified. Dimensional accuracy can be easily ensured and the effect of distortion due to welding is hard to appear because the shape retention of the joint is good.
Therefore, it is possible to reduce the processing cost and manufacture the seat frame at a relatively low cost. Further, the headrest support attaching member attached over the intermediate reinforcing member and the upper frame member can increase the rigidity of the frame and can firmly support the headrest support.
