The restricting portion of this embodiment has a first locking portion 31 and a second locking portion 32, which are integrally provided in the first portion 21 or the second portion 22 (see FIGS. 4 and 5). reference).
And the 1st latching | locking part 31 is a through-hole (substantially rectangular shape by a front view) which penetrates the 1st site | part 21 in the thickness direction, and is long in the elongate direction of the 1st site | part 21. FIG. Each first locking portion 31 has a relatively short dimension W1 (opening size in the seat inside / outside direction), and a second locking portion 32 (claw portion 34) to be described later can be inserted ( (See FIG. 4 (a)).
In the present embodiment, the plurality of first locking portions 31 are formed in parallel in the longitudinal direction of the first portion 21 at appropriate intervals, and outward from the fixing portion (SEW) with the seat cover 6S. Deploy. For example, in the side hook member 20a, three first locking portions 31 are formed and arranged in parallel in the longitudinal direction of the first portion 21 at an appropriate interval.

また第二係止部32は、第二部位22の末端側に連なる平板部位であり、その厚み方向に突出する爪部34を有する(図4(b)を参照)。爪部34は、第二係止部32の末端(内面)から第一部位21に向けて突出する。
そして本実施例では、第二部位22の末端側が、第一係止部31(貫通孔)に対応して複数に分割されており(複数の第二係止部32が形成されており)、それぞれ対応する第一係止部31に挿入可能に配置する。例えば側方フック部材20aでは、第二部位22の末端側が三分割されており、これらの間が切欠き(符号省略)にて区分けされる。
なお他のフック部材では、第一係止部31と第二係止部32の形成数を適宜変更できる。例えば本実施例では、上方フック部材20d〜20fと、下方フック部材20jに、それぞれ第一係止部と第二係止部が一対形成される(なお図1及び図2では、便宜上、各係止部の符号を省略する)。
Moreover, the 2nd latching | locking part 32 is a flat plate part continued in a terminal side of the 2nd site | part 22, and has the nail | claw part 34 which protrudes in the thickness direction (refer FIG.4 (b)). The claw portion 34 protrudes from the end (inner surface) of the second locking portion 32 toward the first portion 21.

For example, in the side hook member 20a, the distal end side of the second portion 22 is divided into three parts, and these are divided by notches (reference numerals omitted).
In other hook members, the number of first locking portions 31 and second locking portions 32 formed can be changed as appropriate. For example, in this embodiment, the upper hook members 20d to 20f and the lower hook member 20j are each formed with a pair of a first locking portion and a second locking portion (in FIG. 1 and FIG. The sign of the stop portion is omitted).

[シートバックの形成作業]
図1〜図3を参照して、シートカバー6Sを、各フック部材20a〜20jを介してシートフレーム6Fに配設してシートバック6を形成する。
本実施例では、シートフレーム6F内にシートカバー6Sを張設しつつ、各フック部材20a〜20jを、対応する掛止部10a〜10cに掛け回し状に嵌めつける(図1及び図5(a)を参照)。
こうして第一部位21と第二部位22を対面状に配置させてこれらの間に各掛止部10a〜10cを保持しつつ、シートカバー6Sにて乗員を弾性的に支持する。そしてこの種の構成では、シートカバー6Sの中央が押圧されるなどして、その端部側が、各フック部材20a〜20jとともに中央に引っ張られる。このとき各フック部材20a〜20jが拡開する向きに過度に撓むなどして、対応する掛止部10a〜10cから抜け外れるおそれがある。
[Forming seat back]
With reference to FIGS. 1 to 3, the seat cover 6 </ b> S is disposed on the seat frame 6 </ b> F via the hook members 20 a to 20 j to form the seat back 6.
In the present embodiment, while hooking the seat cover 6S in the seat frame 6F, the hook members 20a to 20j are hooked around the corresponding latching portions 10a to 10c (FIGS. 1 and 5 (a)). )).
In this way, the first portion 21 and the second portion 22 are arranged in a face-to-face manner, and the occupant is elastically supported by the seat cover 6S while holding the latching portions 10a to 10c therebetween. In this type of configuration, the center of the seat cover 6S is pressed, and the end side is pulled to the center together with the hook members 20a to 20j. At this time, the hook members 20a to 20j may be excessively bent in the expanding direction or the like, and may be detached from the corresponding latching portions 10a to 10c.

そこで本実施例では、各フック部材20a〜20jに規制部31,32を設けて、第一部位21と第二部位22の離間方向の相対移動を規制する(これらの対面状態を維持する)構成とした。
例えば図4及び図5を参照して、側方フック部材20aを第二掛止部10bに嵌めつけつつ、第一部位21と第二部位22を対面状に配置させる。そして各第二係止部32を、ロール状に内向きに湾曲させながら第一係止部31に挿入して、爪部34を、第一係止部31のシート外側の縁部(長尺方向に沿って延びる縁部)に係止する。
こうして第一係止部31と第二係止部32の係止により、第一部位21に対する第二部位22の離間方向の相対移動(拡開方向の撓み)が規制されてこれらの対面状態が維持されることとなる。さらに本実施例では、爪部34が、第一係止部31のシート外側の縁部に係止する。このため側方フック部材20aがシート中央に張引されるに従って、次第に第一係止部31に対して第二係止部32が強く押付けられる(係止が強くなる)構成である(図5(b)を参照)。
このため本実施例では、シートカバー6Sが、各フック部材20a〜20jとともに中央に引っ張られても、規制部31,32にて、各フック部材20a〜20jの過度の撓みが規制されてその抜け外れを防止又は低減できる。
Therefore, in the present embodiment, the restricting portions 31 and 32 are provided on the hook members 20a to 20j to restrict the relative movement in the separating direction between the first portion 21 and the second portion 22 (maintaining these facing states). It was.

And each 2nd latching | locking part 32 is inserted in the 1st latching | locking part 31, curving inward in roll shape, and the nail | claw part 34 is made into the edge part (elongate) of the sheet | seat outer side of the 1st latching | locking part 31. (Edges extending along the direction).
In this way, by the locking of the first locking portion 31 and the second locking portion 32, the relative movement (bending in the expanding direction) of the second portion 22 with respect to the first portion 21 is restricted, and these facing states are prevented. Will be maintained. Further, in the present embodiment, the claw portion 34 is locked to the edge portion of the first locking portion 31 outside the seat. Therefore, as the side hook member 20a is pulled to the center of the sheet, the second locking portion 32 is gradually pressed against the first locking portion 31 (the locking becomes stronger) (FIG. 5). (See (b)).
For this reason, in this embodiment, even if the seat cover 6S is pulled to the center together with the hook members 20a to 20j, excessive restriction of the hook members 20a to 20j is restricted by the restricting portions 31 and 32, and the seat cover 6S is removed. Detachment can be prevented or reduced.

以上説明したとおり本実施例では、各フック部材20a〜20jの張引時に、規制部31,32にて第一部位21に対する第二部位22の拡開方向の相対移動を規制する。このため各フック部材20a〜20jが各掛止部10a〜10cから抜け外れることを防止又は低減することができる。
また本実施例では、各フック部材20a〜20jと一体の規制部31,32(比較的シンプルな構成)にて、各フック部材20a〜20jの抜け外れを防止又は低減できる。
そして本実施例では、各フック部材20a〜20jがシート中央に張引されるに従って、次第に第一係止部31と第二係止部32の係止が強くなる構成である。
このため本実施例によれば、シートカバー6S(面状部材)を、各フック部材20a〜20jを介してシートフレーム6F(支持部材)により安定的に係止することができる。
As described above, in the present embodiment, when the hook members 20a to 20j are stretched, the restricting portions 31 and 32 restrict relative movement of the second part 22 in the expanding direction with respect to the first part 21. For this reason, it can prevent or reduce that each hook member 20a-20j slips out from each latching | locking part 10a-10c.
In the present embodiment, the hook members 20a to 20j can be prevented from coming off or reduced by the restricting portions 31 and 32 (relatively simple configuration) integrated with the hook members 20a to 20j.
In this embodiment, as the hook members 20a to 20j are pulled in the center of the seat, the first locking portion 31 and the second locking portion 32 are gradually locked.
Therefore, according to the present embodiment, the seat cover 6S (planar member) can be stably locked by the seat frame 6F (support member) via the hook members 20a to 20j.
