For the description of this part, the description in the above embodiment can be used as appropriate within a technically consistent range. Also, part of the above-described embodiments and all or part of the modifications can be applied in combination as appropriate within a technically consistent range.

A blindfold part in a modified example will be described with reference to FIG. FIG. 5 is a sectional view of a blindfold part in a modified example corresponding to FIG.

As shown in FIG. 5, in the modified example, a resin plate 39 is sewn into a cloth 35 as a core material in place of the wire core wire 34 as the core material of the blinds 32 and 33 of the embodiment. The resin plate 39 is a resin plate used as a core material of a sheet pocket, and is, for example, a closed-cell sheet (PP 1.3 times foamed sheet) obtained by extruding and foaming polypropylene to about 1.3 times. More specifically, the vicinity of the edge of the cloth 35 is folded back, the resin plate 39 is passed through the folded portion 35a, and the entire surface of the resin plate 39 facing the seated person and the vicinity of the edge of the opposite surface of the resin plate 39 are covered with the cloth 35. The surface 35b on the side of the seat and the surface 35c on the opposite side are fixed by sewing thread 36. As shown in FIG. The blindfold part 33 has the same configuration as the blindfold part 32 .

In this embodiment and its modification, the headrest is provided with a pair of left and right blindfolds that can be stored by combining a wire core or a resin core material with cloth, and the blindfolds are configured to be fixed by hook-and-loop fasteners or the like. . Unlike a sun visor that reduces the glare of sunlight, cloth is used instead of a transparent or semi-transparent plate-shaped light shielding body to reduce glare by cutting ultraviolet rays while securing a certain transmittance of visible light. Since it does not transmit visible light, the left and right vision can be blocked by using cloth without any sense of danger. In addition, it is possible to obtain a personal feeling of the seated person. Moreover, the combination of the cloth and the core material enables a lightweight and simple construction, so that the problem of Patent Document 1 described above can be solved. Furthermore, it also serves as a protective wall when the glass is scattered due to an accident or the like, and can contribute to safety.
