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.

Abstract: An automobile seat comprising a main foam pad and a sub-pad made of a softer foam material relative to the foam cushion body, the sub-pad being mounted on the main foam pad. In this seat, a covering member is provided over those pads such that the section of the covering member which covers the sub-pad is fixed in a dotted manner to the section thereof which covers the main foam pad. With this arrangement, a plurality of decorative creases are created in the lateral side portions of the covering member section which covers the lateral surfaces of the sub-pad.
