The flange portion 25B of the pillar support member 25 is disposed on the upper surface of the recess bottom portion 42, and sandwiches the recess bottom portion 42 with the recess bottom wall 30A of the seatback pad 12. Thus, the concave bottom surface portion 42 is fixed on the concave bottom wall 30A of the seatback pad 12 without slack by the pillar support member 25.

  By covering the surface material 13 on the seat back pad 12 and covering the surface of the pad-side recess 30 and the front surface of the front plate 20A of the bracket 20 with the recess bottom 42, recess side 43 and recess rear side 44, A headrest storage recess 60 is formed on the upper end front side of the seat back 3. A headrest storage recess 60 is formed by the recess formed by the pad-side recess 30 and the bracket 20 in cooperation with each other and the skin material 13. The headrest storage recess 60 is recessed on the upper front side of the seat back 3 and opens forward and upward. The bottom of the headrest storage recess 60 is formed by the recess bottom portion 42, the left and right side surfaces are formed by the left and right recess side portions 43, and the rear side surface is formed by the recess rear side portion 44 to form a substantially rectangular parallelepiped. When the headrest 4 is in the lowermost position as shown in FIGS. 1 and 5, the rear of the headrest 4 is stored in the headrest storage recess 60.

  The effects of the seat 1 configured as described above will be described. In the present embodiment, the rear wall portion of the headrest storage recess 60 is formed by covering the bracket 20 with the skin material 13. The support plate 50 is sewn on the back surface of the concave back surface portion 44 constituting the skin material 13 and coupled to the front plate portion 20A of the bracket 20 with the support plate 50 facing forward and backward. This can be along the front plate portion 20A, and the position of the recess rear side surface portion 44 is stabilized. Further, when a load is applied from the outside, the front plate portion 20A supports the skin material 13 from the back surface side, and the extension of the skin material 13 is suppressed. Thereby, the slack of the surface material 13 is suppressed. The recess side surface portion 43 and the recess rear side portion 44 are supported by the recess bottom wall 30A and the recess side wall 30B that constitute the pad-side recess 30, so that slack is also suppressed.

  The positioning of the support plate 50 relative to the bracket 20 is facilitated by the support plate 50 being received in the plate receiving recess 20D. Further, since the amount of forward protrusion of the support plate 50 with respect to the bracket 20 is reduced, the skin material 13 can be more easily along the front plate portion 20A of the bracket 20.

  Since the skin material 13 is sewn to the support plate 50 at a position corresponding to the lower end portion and the rear end of the pad side recess 30, the cover 13 is fixed to the support plate 59 at the deepest portion of the headrest storage recess 60. Therefore, the skin material 13 is disposed on the surface of the pad-side recess 30 and the surface of the bracket 20 without slack.

  The bracket 20 is coupled to the upper frame 16, the extension frame 18, and the pan frame 21, so the position is stabilized and it is difficult to deform. Therefore, the bracket 20 can support the support plate 50 with high stability. Further, the bracket 20 forms a high rigidity portion which is not easily deformed at the upper end portion of the seat back 3. As a result, it is possible to stably support the tether extending from the child seat attached to the seat 1 through the upper end of the seat back 3 and extending downward to the rear.

  Although the description of the specific embodiment is finished above, the present invention can be widely modified and implemented without being limited to the above embodiment. For example, the shape of the bracket 20 is not limited to the above embodiment, and can be changed as appropriate. For example, the plate receiving recess 20D, the first connecting recess 20E, and the second connecting recess 20F are not essential components and can be selected.
