an outer frame of a seatback frame, the outer frame forming a framework of a seatback of the vehicle seat;
a frame bracket coupled to a coupling location of the outer frame, the coupling location being located on a coupling side, which is either of the left or right side, of the outer frame;
a module bracket fastened to the frame bracket at one or more fastening points and configured to support an airbag module;
a pan frame coupled to the rear side of the outer frame; and
a shape former coupled to the outer frame on the coupling side, and configured to form an outer shape of the seatback,
wherein the pan frame includes a protrusion section protruding from an upper portion of the pan frame on the coupling side such that the fastening points are located below the protrusion section,
wherein at least part of the airbag module is positioned frontward of the protrusion section along the front-rear direction of the vehicle seat,
wherein the shape former is coupled to the protrusion section,
wherein the outer frame comprises two side frames on the left and right sides, and an upper frame connecting the two side frames,
wherein the frame bracket is coupled to a side frame, one of the two side frames on the coupling side, at points in front and rear edges of the side frame,
wherein the shape former is a curved wire member having a shape former upper portion, a shape former lower portion, and a shape former center portion connecting the shape former upper portion and the shape former lower portion,
wherein the shape former is coupled to the side frame so that the shape former protrudes outward from the side frame,
wherein the shape former center portion includes an upper half portion which extends along an outer edge of the protrusion section of the pan frame and a lower half portion which extends downward from a lower end of the upper half portion, and
wherein a through-hole space extending in the front-rear direction is defined by the shape former, the protrusion section, and the side frame, the through-hole space being formed rearward of the fastening points.
