FRAME STRUCTURE OF VEHICLE SEAT BACK AND VEHICLE SEAT BACK WITH THE STRUCTURE

摘要

<P>PROBLEM TO BE SOLVED: To provide the frame structure of a vehicle seat back which achieves a weight reduction in the entire structure while securing strength required for the seat back while flexibly coping with restrictions on a space requested for the frame structure without lowering manufacture efficiency. Ž<P>SOLUTION: The vehicle seat back frame structure has planar side frames 12 disposed such that they are paired on the right and left side of the seat back and the plate width is positioned in the anteroposterior direction of a vehicle in order to form the frame backbone of the seat back. Each of the side frames 12 has a closed cross-section part 26 in which the planar side frame 12 is formed into a closed cross-section in a direction roughly orthogonal to the height direction in a front edge part 22 and a rear edge part 24 respectively over the entire height direction.
