この種の車両用シートとして、特許文献１に開示の車両用シートが公知である。この車両用シートは、シートクッションと、シートバックと、ヘッドレストを有する。ヘッドレストの下部には、一対のステー部材（棒状の部材）が所定間隔をあけて突設される。
またシートバックは、シートクッションに起立可能に連結する部材（金属製）であり、シート外形をなすフレーム部材と、一対の付属部材を有する。フレーム部材は、アーチ状の枠体（中空筒状）であり、上部骨格をなす上部フレームと、側部骨格をなす側部フレームを有する。また一対の付属部材はともに筒状部材であり、それぞれステー部材を挿設できる。
公知技術では、上部フレーム（被取付け部）に一対の切込みを二組設けたのち、これら切欠きの間を押し潰して一対の凹み部位（嵌込み部）を設ける。そしてこれら一対の凹み部位にそれぞれ付属部材を嵌込み状に固定したのちステー部材を挿設することで、シートバック上部にヘッドレストを固定できる。 As this type of vehicle seat, a vehicle seat disclosed in Patent Document 1 is known. The vehicle seat includes a seat cushion, a seat back, and a headrest. A pair of stay members (bar-shaped members) are projected from the lower portion of the headrest at a predetermined interval.
The seat back is a member (made of metal) that is connected to the seat cushion so as to stand upright, and includes a frame member that forms a seat outer shape and a pair of attached members. The frame member is an arch-shaped frame (hollow cylindrical shape), and includes an upper frame forming an upper skeleton and a side frame forming a side skeleton. Further, the pair of attachment members are both cylindrical members, and a stay member can be inserted in each of them.
In the known technique, after two pairs of cuts are provided in the upper frame (attached portion), a pair of recessed portions (inserted portions) is provided by crushing between the notches. The headrest can be fixed to the upper portion of the seat back by inserting the stay member after fixing the attachment member to the pair of recessed portions, respectively.

ところで公知技術では、フレーム部材（中空筒状）を部分的に押し潰して一対の凹み部位を形成する。このとき公知技術では、フレーム部材が過度に押し潰される（過度に変形する）などして剛性が低下することがあった。
本発明は上述の点に鑑みて創案されたものであり、本発明が解決しようとする課題は、フレーム部材の剛性を極力維持しつつ付属部材を取付け可能とすることにある。 By the way, in a well-known technique, a frame member (hollow cylinder shape) is partially crushed and a pair of recessed part is formed. At this time, in the known technique, the frame member may be excessively crushed (deform excessively), and the rigidity may be reduced.
The present invention has been devised in view of the above points, and a problem to be solved by the present invention is to enable attachment of an attachment member while maintaining the rigidity of the frame member as much as possible.

上記課題を解決するための手段として、第１発明の車両用シートは、シートクッションやシートバック等のシート構成部材を有する。そしてシート構成部材が、シート骨格をなすフレーム部材と、フレーム部材の一部又は全部をなす中空筒状で金属製の被取付け部と、支持ブラケットなどの付属部材を備える。
本発明では、被取付け部に対して切欠き状又は孔状などの嵌込み部を形成する。そして付属部材を嵌込み状に取付けるのであるが、この種の構成では、フレーム部材の剛性を極力維持しつつ付属部材を取付けられることが望ましい。
そこで本発明では、被取付け部が、面状の金属部材に嵌込み部を設けたのち、中空筒状に成形されてなる。このように本発明では、面状の金属部材に対して嵌込み部（切欠き状や孔状等）を形成するため、成形後のフレーム部材を部分的に押し潰す必要がない（フレーム部材の変形を極力回避できる）。 As means for solving the above-mentioned problems, the vehicle seat of the first invention has a seat constituent member such as a seat cushion or a seat back. The seat constituent member includes a frame member that forms a seat skeleton, a hollow cylindrical metal mounting portion that forms part or all of the frame member, and an attachment member such as a support bracket.
In the present invention, a fitting portion such as a notch shape or a hole shape is formed in the attached portion. The attachment member is attached in a fitting manner. In this type of configuration, it is desirable that the attachment member can be attached while maintaining the rigidity of the frame member as much as possible.
Therefore, in the present invention, the mounted portion is formed into a hollow cylindrical shape after the fitting portion is provided in the planar metal member. As described above, in the present invention, since the fitting portion (notch shape, hole shape, or the like) is formed on the planar metal member, it is not necessary to partially crush the frame member after molding (the frame member). Deformation can be avoided as much as possible).

本発明に係る第１発明によれば、フレーム部材の剛性を極力維持しつつ、付属部材を取付け可能とすることができる。   According to the first aspect of the present invention, the attachment member can be attached while maintaining the rigidity of the frame member as much as possible.

In the present embodiment, the pair of fitting portions 6c can be formed on the upper frame portion 6a with a predetermined interval (clearance corresponding to the gap between the pair of stay members 8a) (in the drawing, for convenience, one fitting portion is provided). Only 6c is shown).

（支持ブラケット（付属部材））
そして支持ブラケット１０（略矩形）は、典型的に剛性を有する金属製の部材であり、フレーム部材６Ｆに嵌込み部６ｃを介して固定可能である（図２を参照）。

［フレーム部材の作成］
本実施例では、面状の金属部材３０を中空筒状に成形してフレーム部材６Ｆを作成する（図２及び図３を参照）。
金属部材３０は、フレーム部材６Ｆの展開形状に倣った面状部材であり、複数の折れ線部３２を有する。複数の折れ線部３２は、金属部材３０表面の線状の凹み部であり、金属部材３０の屈曲変形時の折代となる部位である。
ここで金属部材３０の材質は特に限定しないが、変形可能な金属であることが好ましく、鋼系（ステンレス鋼等）、アルミニウム合金系、マグネシウム合金系、チタン合金系等の金属を例示できる。 [Create frame member]
In the present embodiment, the planar metal member 30 is formed into a hollow cylindrical shape to create the frame member 6F (see FIGS. 2 and 3).
The metal member 30 is a planar member that follows the developed shape of the frame member 6 </ b> F, and has a plurality of broken line portions 32. The plurality of broken line portions 32 are linear dent portions on the surface of the metal member 30, and are portions serving as folding margins when the metal member 30 is bent and deformed.
Here, the material of the metal member 30 is not particularly limited, but is preferably a deformable metal, and examples thereof include steel (such as stainless steel), aluminum alloy, magnesium alloy, and titanium alloy.

（嵌込み部の形成）
本実施例では、一対の嵌込み部６ｃ（略長方形状の貫通孔Ｈ）を、金属部材３０の一部に所定間隔をあけて形成する（図３（ａ）では、便宜上一つの嵌込み部のみを図示する）。このとき嵌込み部６ｃ（略長方形状の貫通孔Ｈ）は、上部フレーム部６ａの途中に相当する部位（後述の第一面３０Ａ）に形成できる（図２及び図３（ｂ）を参照）。
ここで嵌込み部６ｃ（貫通孔Ｈ）の形成方法は特に限定しないが、パンチ機構やプレス型等を用いたプレス加工や、レーザなどの光学的加工を例示できる。
このように金属部材３０（面状）に対して嵌込み部６ｃを形成することにより、例えばプレス加工等においてフレーム部材６Ｆを過度に凹ませることを極力回避できる。そして本実施例では、面状の金属部材３０に対してプレス加工することにより、中空筒状としたのちにプレス加工する場合と比較して、どのような場所でも比較的容易に一対の貫通孔Ｈ（嵌込み部６ｃ）を形成できる。 (Formation of fitting part)
In the present embodiment, the pair of fitting portions 6c (substantially rectangular through holes H) are formed at a predetermined interval in a part of the metal member 30 (in FIG. 3A, one fitting portion for convenience). Only shown). At this time, the fitting portion 6c (substantially rectangular through hole H) can be formed in a portion (first surface 30A described later) corresponding to the middle of the upper frame portion 6a (see FIGS. 2 and 3B). .
Here, the method of forming the fitting portion 6c (through hole H) is not particularly limited, and examples thereof include press processing using a punch mechanism, a press die, and the like, and optical processing such as laser.
Thus, by forming the fitting part 6c with respect to the metal member 30 (plane shape), it can avoid as much as possible that the frame member 6F is dented too much in press work etc., for example. In this embodiment, the pair of through-holes is relatively easy at any place as compared to the case of pressing the sheet-like metal member 30 after pressing it into a hollow cylinder. H (the fitting portion 6c) can be formed.

（変形例）
ここでフレーム部材６Ｆには、支持ブラケット１０のほか、各種の付属部材を取付けることができる。付属部材の種類は特に限定しないが、エアバック及びその付属部材（図示省略）や、モータ等の電動機器（図示省略）を例示できる。
例えば一方の側部フレーム部６ｂの外面（被取付け部の他例）に、孔状の第一嵌込み部６ｄを設けて、エアバック及びその付属部材を取付けることができる。また他方の側部フレーム部６ｂの内面（被取付け部の他例）に、孔状の第二嵌込み部６ｅを設けて、モータ等の電動機器を取付けることもできる。
そして本実施例では、面状の金属部材３０に対して、一つのプレス型により複数の嵌込み部６ｃ〜６ｅ（切欠きや孔）を同時に形成できる（形成作業を簡略化できる）。 (Modification)
Here, in addition to the support bracket 10, various attachment members can be attached to the frame member 6F. Although the kind of attachment member is not specifically limited, An airbag and its attachment member (illustration omitted) and electric equipments (illustration abbreviation), such as a motor, can be illustrated.
For example, a hole-like first fitting portion 6d can be provided on the outer surface of the one side frame portion 6b (another example of the attached portion), and the airbag and its attached members can be attached. In addition, a hole-like second fitting portion 6e may be provided on the inner surface of the other side frame portion 6b (another example of the attached portion) to attach an electric device such as a motor.
In the present embodiment, a plurality of fitting portions 6c to 6e (notches and holes) can be simultaneously formed on the planar metal member 30 with a single press die (the forming operation can be simplified).

つぎに金属部材３０（面状）を、各折れ線部３２で屈曲させて中空筒状（断面視で略矩形）に成形する（図３（ａ）（ｂ）を参照）。
このとき金属部材３０の一対の端部３４を対面状に当接配置したのち（閉合部３６を形成したのち）、一対の端部３４同士を一体化する。こうすることで閉合部３６の拡開（フレーム部材６Ｆの変形）が極力阻止されて、フレーム部材６Ｆの変形による剛性低下を極力回避できる。
ここで端部３４同士の一体化の手法は特に限定しないが、溶接や接着などの手法を例示できる。また一方の端部３４を凹凸状とし、他方の端部３４を凹凸状とする。そしてこれら両端部３４を互いに噛合せて一体化することもできる。 Next, the metal member 30 (planar shape) is bent at each broken line portion 32 to be formed into a hollow cylindrical shape (substantially rectangular in a cross-sectional view) (see FIGS. 3A and 3B).
At this time, after the pair of end portions 34 of the metal member 30 are disposed so as to face each other (after the closing portion 36 is formed), the pair of end portions 34 are integrated. By doing so, the expansion of the closing portion 36 (deformation of the frame member 6F) is prevented as much as possible, and a reduction in rigidity due to the deformation of the frame member 6F can be avoided as much as possible.
Here, the method of integrating the end portions 34 is not particularly limited, and examples thereof include methods such as welding and adhesion. In addition, one end 34 is uneven, and the other end 34 is uneven. These both end portions 34 can be integrated with each other.

そして本実施例では、金属部材３０を中空筒状（断面視で略矩形）とすることで、第一面３０Ａ〜第四面３０Ｄが形成される（図３（ｂ）を参照）。
第一面３０Ａは、シートバック６の着座側を臨む面であり、第二面３０Ｂは、シートバック６の後側を臨む面である。そして第三面３０Ｃは、シートバック６の内側を臨む面（内面）であり、第四面３０Ｄは、シートバック６の外側を臨む面（外面）である。
そして本実施例では、金属部材３０（中空筒状）を、略アーチ状に曲げ加工しつつ、複数の変形部（第一変形部Ｒ１，第二変形部Ｒ２等）を形成する（図２を参照）。
このとき当該変形部分において、第三面３０Ｃ（内面）に対して縮み方向の応力がかかり、第四面３０Ｄ（外面）に伸び方向の応力がかかる（周長差が生じる）などして、閉合部３６が拡開することが懸念される。そこで本実施例では、閉合部３６を、第二面３０Ｂ（後側の面）に形成することで、極力変形時の応力がかからない構成とすることができる（周長差の発生が原因の拡開変形を極力回避できる）。また閉合部３６を、嵌込み部６ｃ（第一面３０Ａ）とは異なる位置に形成することで、フレーム部材６Ｆの剛性低下を極力回避できる。 In the present embodiment, the first surface 30A to the fourth surface 30D are formed by forming the metal member 30 in a hollow cylindrical shape (substantially rectangular in cross-sectional view) (see FIG. 3B).
The first surface 30 </ b> A is a surface facing the seating side of the seat back 6, and the second surface 30 </ b> B is a surface facing the rear side of the seat back 6. The third surface 30 </ b> C is a surface (inner surface) facing the inner side of the seat back 6, and the fourth surface 30 </ b> D is a surface (outer surface) facing the outer side of the seat back 6.
In this embodiment, the metal member 30 (hollow cylindrical shape) is bent into a substantially arch shape, and a plurality of deformation portions (first deformation portion R1, second deformation portion R2, etc.) are formed (see FIG. 2). reference).
At this time, in the deformed portion, a stress in the shrinking direction is applied to the third surface 30C (inner surface), and a stress in the extending direction is applied to the fourth surface 30D (outer surface) (peripheral length difference is generated). There is a concern that the portion 36 may expand. Therefore, in the present embodiment, by forming the closing portion 36 on the second surface 30B (rear surface), it is possible to adopt a configuration in which stress during deformation is not applied as much as possible (expansion due to the occurrence of a circumferential length difference). Open deformation can be avoided as much as possible). Moreover, the rigidity reduction of the frame member 6F can be avoided as much as possible by forming the closing part 36 at a position different from the fitting part 6c (first surface 30A).

そして各嵌込み部６ｃに、支持ブラケット１０を嵌込みつつ溶接等にて固定することで、それぞれステー部材８ａを挿設可能に配置する。
つぎにクッション材６Ｐを、フレーム部材６Ｆ上に配置して表皮材６Ｓで被覆する。表皮材６Ｓとクッション材６Ｐの上部には、それぞれ一対の貫通孔（符号省略）が形成されており、支持ブラケット１０を外部に露出可能である。そして一対のステー部材８ａを、それぞれ対応する支持ブラケット１０に挿設することで、シートバック６上部にヘッドレスト８を取付けることができる。 Then, by fixing the support bracket 10 to each fitting portion 6c by welding or the like, the stay members 8a are respectively arranged so as to be insertable.
Next, the cushion material 6P is disposed on the frame member 6F and covered with the skin material 6S. A pair of through holes (reference numerals omitted) are formed in the upper parts of the skin material 6S and the cushion material 6P, respectively, and the support bracket 10 can be exposed to the outside. The headrest 8 can be attached to the upper portion of the seat back 6 by inserting the pair of stay members 8a into the corresponding support brackets 10 respectively.

以上説明したとおり本実施例では、面状の金属部材３０に対して嵌込み部６ｃ（切欠き状や孔状等）を形成する。このため成形後のフレーム部材６Ｆを部分的に押し潰す必要がないことからフレーム部材６Ｆの変形を極力回避できる。
よって本実施例によれば、フレーム部材６Ｆの剛性を極力維持しつつ、支持ブラケット１０（付属部材）を取付け可能とすることができる。 As described above, in the present embodiment, the fitting portion 6 c (notch shape, hole shape, or the like) is formed on the planar metal member 30. For this reason, since it is not necessary to partially crush the frame member 6F after molding, deformation of the frame member 6F can be avoided as much as possible.
Therefore, according to the present embodiment, the support bracket 10 (attachment member) can be attached while maintaining the rigidity of the frame member 6F as much as possible.

(2) In the present embodiment, the configuration (shape, dimension, number of formation) of the fitting portion 6c is exemplified, but the configuration of the same portion can be appropriately changed according to the sheet configuration. For example, in this embodiment, the fitting portion 6c and the closing portion 36 are formed at different positions. Unlike this, the fitting portion and the closing portion can be formed at the same position (for example, both on the first surface). At this time, a notch is provided at one end of the metal member, and a notch is provided at the other end. And a fitting part can be formed by abutting both ends and combining both notches.

（４）また本実施形態では、金属部材３０の一対の端部３４同士を対面状に配置する例を説明した。これとは異なり一対の端部同士を重ねた状態で当接配置することもできる。このように端部同士を重ねつつ溶接することで閉合部をより強固に一体化できる。
（５）また本実施形態では、一枚の金属部材３０を用いる例を説明した。これとは異なり一対の金属部材（面状）を、それぞれ略Ｕ字状に屈曲させたのち、これらを一体化して中空筒状（断面視で略矩形状）とすることもできる。
（６）また本実施形態では、シートバック６を一例に説明したが、本実施例の構成は、シートクッション４等の各種シート構成部材に適用できる。 (3) In the present embodiment, the entire frame member 6F is formed into a hollow cylindrical shape, but this is not intended to limit the configuration of the frame member 6F. For example, the upper frame portion can be formed into a hollow cylindrical shape, and the side frame portion can be formed into a flat plate shape.
(4) Moreover, in this embodiment, the example which arrange | positions a pair of edge parts 34 of the metal member 30 facing each other was demonstrated. Unlike this, it is also possible to place a pair of end portions in contact with each other. In this way, the closing portion can be more firmly integrated by welding while overlapping the end portions.
(5) Moreover, in this embodiment, the example using the single metal member 30 was demonstrated. On the other hand, after a pair of metal members (planar shapes) are bent into a substantially U shape, they can be integrated into a hollow cylindrical shape (substantially rectangular shape in cross section).
(6) In the present embodiment, the seat back 6 has been described as an example, but the configuration of the present embodiment can be applied to various seat components such as the seat cushion 4.
