ABSTRACT:
A rear structure of a seat back for an automotive seat is disclosed. In order to increase the depth dimension of a seat cushion, a rearwardly curved reinforcing rod is welded to the lower portion of an inverted U-shaped frame forming the seat, and the shape holding portions of a cushion member thicker than the turned-back portions thereof covering the upper portion of the frame are applied against the frame with the rod welded thereto. The outer surfaces of the shape holding portions are arranged to form the same plane with the outer surfaces of the turned-back portions, so that the right and left corners of the rear portion of the seat back can be formed square.
