According to the headrest 1 according to the present invention, a headrest body (see FIGS. 10 and 11) composed of a headrest frame 3 and a pad material 4 provided at the upper end portions of the headrest stays 2 and 2 and an outer peripheral portion thereof are provided. The trim cover 10 includes a trim cover 10 to be covered, and a finisher 11 that covers a joining edge portion of the trim cover 10.

As is apparent from FIG. 8, the above-described trim cover 10 is formed of a single substantially rectangular skin material, and the opposite ends of the trim cover 10 are positioned at the left and right sides.
Hook means 12a, 12b; 13 hooked and joined to each other at positions separated by a predetermined distance on each of the right edges
a, 13b; 14a, 14b are sewn together, and both ends of the sewing thread 15 are drawn down at the center of the side edge, whereby the headrest frame 3 is clipped by the ring clip 17 (see FIG. 4). The portion 16 is formed by sewing over a predetermined range.

Here, the hook means 12a, 12
b, 13a, 13b; 14a, 14b are composed of, for example, a resin bar and a resin hook having a curved locking groove, and as shown in FIGS. By stopping, trim cover 1
Each edge of 0 can be joined with one touch.

In FIG. 8, reference numerals 18a, 18a; 1
8b and 18b are notches for inserting the above-mentioned ring clip 17, and 19 and 19 are notches for stays which escape the headrest stays 2 and 2. Further, in the drawing, reference numeral 20 denotes a state where the draw-drawing portion 16 is covered with the trim cover 10 on the pad material 4 as shown in FIGS. 9 (a) and 9 (b). It is a wrinkle-generating portion having a natural feeling generated by sequentially pulling and binding the yarn. Here, it is preferable to sew the pulling and narrowing portion 16 by, for example, esekomi sewing.

Further, in FIG. 10 and FIG.
Reference numeral 1 denotes a hole for the ring clip 17 recessed in the side surface of the headrest frame 3, and 22 denotes a finisher 11 which is bent and formed to have a substantially U-shape and is assembled over the bottom surface and both side surfaces of the headrest 1. It is a hole for engaging the locking claws 23 provided on the bent portions 11a.

According to the above configuration, the trim cover 10

Moreover, it can be easily mounted without causing a problem such as shape collapse.

In other words, in such a configuration, the trim cover 10 which is a skin material encapsulated in the outer periphery of the headrest frame 3 and the pad material 4 constituting the headrest body is simply formed by a single skin material. In addition, it can be formed with a minimum number of sewing parts, does not cause a shape collapse problem when it is put on the pad material 4, and can more positively form a wrinkle 20 or the like by well-drawn by drawing, thereby producing a trim cover. It can reduce man-hours and cost, and it is not necessary to turn over or apply excessive force when coating the pad material, and it is possible to improve workability during processing and assembly, and to improve appearance. And the headrest 1 having good appearance and low cost can be obtained.

In particular, in the above-described configuration, in the pull-down portions 16, 16 from which the sewing thread 15 has been drawn, wrinkles due to a desired pull-down can be formed very easily on the side portion of the headrest 1 with a natural feeling just by pulling. This has a great practical advantage compared to a conventional trim cover formed by combining a plurality of pieces. In short, it is preferable to press the center portion of the wrinkle with the ring clip 17.

Further, according to the above-described configuration, the trim cover 10 is provided with a substantially U-shaped finisher 11 which covers the bottom surface and both side surfaces of the headrest 1 where the joining edge exists, thereby providing an overall structure. As a result, the appearance is good, the appearance is excellent, and the quality of the product and the effect on its design can be greatly improved.

It should be noted that the present invention is not limited to the structure of the embodiment described above, and the shape, structure, etc. of each part may be appropriately modified as necessary.
It is free to change. For example, various modifications are conceivable as the shape of the headrest frame 3 and the pad material 4 constituting the headrest body, the interval between the sewing threads 15 of the drawing portion 16, and the like, and the same applies to other components. Needless to say.
