In the fabric material, one part of the first piece 40f is connected to the second piece 40s and also the conductive threads are electrically connected to a power source in the other part of the first piece 40f different from the one part.

Description

本発明は、導電糸(通電可能な糸材)を有する面状の第一ピースと、第一ピースとは異なる面状の第二ピースをつなげてなる布材に関する。   The present invention relates to a cloth material formed by connecting a planar first piece having conductive yarn (a thread material that can be energized) and a planar second piece different from the first piece.

この種の布材として、特許文献1に開示の車両用シートの表皮材が公知である。この表皮材は、織物や編物等の複数の表皮ピース(第一ピースや第二ピース等)を有する。そして第一ピースには、複数の導電糸が織り込まれており(又は編み込まれており)、通電可能とされる。
ここで複数の導電糸は、適宜の間隔で並列配置しつつ、それぞれ第一ピースの一端から他端にかけて線状に延びる。そして各導電糸の端部を、接続部材(銅線等を備えた帯体)を介して電源につなげる。このように導電糸を通電状態とすることにより表皮材(第一ピース)を、静電容量式センサの電極やヒータとして機能させることができる。
As this type of cloth material, a skin material for a vehicle seat disclosed in Patent Document 1 is known. This skin material has a plurality of skin pieces (a first piece, a second piece, etc.) such as a woven fabric or a knitted fabric. The first piece is woven (or knitted) with a plurality of conductive yarns, and can be energized.
Here, the plurality of conductive yarns extend linearly from one end to the other end of the first piece while being arranged in parallel at an appropriate interval. And the edge part of each electrically conductive thread | yarn is connected to a power supply through a connection member (strip | belt body provided with the copper wire etc.). By making the conductive yarn in an energized state in this way, the skin material (first piece) can function as an electrode or a heater of a capacitive sensor.

そして公知技術の表皮材は、複数の表皮ピース(第一ピースや第二ピース等)をミシンにて縫合することで形成される。
例えば第一ピースの端部を、第二ピースの端部に重ね合わせる。そしてミシンに対して各ピースを所定の送り量で相対移動させつつ、所定のピッチでミシン針を刺し通すことにより、重ね合わせた部分を縫合する(複数のミシン目からなる縫合線を形成する)。
A known skin material is formed by sewing a plurality of skin pieces (first piece, second piece or the like) with a sewing machine.
For example, the end of the first piece is overlapped with the end of the second piece. Then, each piece is moved relative to the sewing machine by a predetermined feed amount, and the overlapped portion is stitched by piercing the sewing needle at a predetermined pitch (forms a suture line composed of a plurality of perforations). .

特開2010−94283号公報JP 2010-94283 A

ところで公知技術では、複数の導電糸が、第一ピースの一端から他端にかけて線状に配置する(第一ピースの端部に配置する)。このため各ピースの端部同士をミシンにて縫合する際に、複数のミシン目からなる縫合線が導電糸と交差するなどして、ミシン針にて導電糸が断線することがあった。
もっとも縫製を避けるために接続部材を、両ピース同士をあわせる(つなげる)間に配置することも行われているが、接続部材は銅線などを配置するために固くなりやすく、違和感・座り心地が悪くなる。また着座など強く変形させられる位置に接続部材が配置することになるため、屈曲耐久性に対して不利になる。このため典型的には接続部材を、両ピースをつなぎ合わせた外側の端に配置することが好ましく、こうすることでつなぎ合わせにより固定され、両ピースの動きも制限されるために屈曲耐久性としても有利となる。
さらに縫製により、表皮材に孔があけられるため、表皮材を撥水や防水加工しても縫製部から液体がシート内部に侵入し、導電線や接続部の電気分解を誘引していた。
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、隣り合うピース同士を性能良くつなげることにある。
In the known technique, a plurality of conductive yarns are arranged linearly from one end to the other end of the first piece (arranged at the end of the first piece). For this reason, when the ends of each piece are sewn together with a sewing machine, there are cases in which the sewing thread consisting of a plurality of perforations intersects the conductive thread, and the conductive thread breaks with the sewing needle.
However, in order to avoid sewing, it is also possible to place the connecting member between the two pieces together (join), but the connecting member is likely to become stiff due to the placement of copper wire, etc., making it uncomfortable and comfortable to sit on Deteriorate. In addition, since the connecting member is disposed at a position where it can be strongly deformed such as sitting, it is disadvantageous for bending durability. For this reason, it is typically preferable to arrange the connecting member at the outer end where the two pieces are joined together, and as this is fixed by joining, the movement of the two pieces is also limited, so that the bending durability is limited. Is also advantageous.
Further, since holes are made in the skin material by sewing, even if the skin material is subjected to water repellency or waterproofing, liquid enters the inside of the sheet from the sewing portion and induces electrolysis of the conductive wire and the connection portion.
The present invention has been devised in view of the above points, and the problem to be solved by the present invention is to connect adjacent pieces with good performance.

上記課題を解決するための手段として、第1発明の布材は、導電糸を有する面状の第一ピースと、第一ピースとは異なる面状の第二ピースとを備える。
本発明では、第一ピースの一部を第二ピースにつなげるとともに、一部とは異なる第一ピースの他部において導電糸を電源に電気的につなげることができる。この種の構成では、隣り合う第一ピースと第二ピース同士を性能良く(例えば導電糸の断線を極力回避しつつ)つなげられることが望ましい。
そこで本発明では、第一ピースの一部を第二ピースに溶着又は接着にてつなげることとした。このように隣り合うピース同士を溶着又は接着にて(ミシンを用いることなく)つなげることで、導電糸の断線を極力回避することができる。
As means for solving the above-described problems, the cloth material of the first invention includes a planar first piece having conductive yarns and a planar second piece different from the first piece.
In this invention, while connecting a part of 1st piece to a 2nd piece, a conductive thread can be electrically connected to a power supply in the other part of the 1st piece different from a part. In this type of configuration, it is desirable that the adjacent first piece and second piece can be connected with good performance (for example, while avoiding disconnection of the conductive yarn as much as possible).
Therefore, in the present invention, a part of the first piece is connected to the second piece by welding or bonding. In this way, by connecting adjacent pieces by welding or bonding (without using a sewing machine), disconnection of the conductive yarn can be avoided as much as possible.

第2発明の布材は、第1発明の布材であって、第一ピース及び第二ピースよりも熱で溶けやすい連結材が、第一ピースの一部と第二ピースの間に挟まれた状態で固化することにより、第一ピースの一部が第二ピースに溶着にてつなげられる構成である。
本発明では、連結材(各ピースとは別部材)にて、ピース同士を強度性良くつなげることができる。
The cloth material of the second invention is the cloth material of the first invention, and a connecting material that is more easily melted by heat than the first piece and the second piece is sandwiched between a part of the first piece and the second piece. By solidifying in the state, a part of the first piece is connected to the second piece by welding.
In the present invention, the pieces can be connected to each other with high strength by a connecting material (a separate member from each piece).

本発明に係る第1発明によれば、隣り合うピース同士を性能良くつなげることができる。また第2発明によれば、隣り合うピース同士を更に性能良くつなげることができる。   According to the first invention of the present invention, adjacent pieces can be connected with good performance. Further, according to the second invention, adjacent pieces can be connected with better performance.

以下、本発明を実施するための形態を、図1〜図5を参照して説明する。各図には、適宜、車両用シート前方に符号F、車両用シート後方に符号B、車両用シート上方に符号UP、車両用シート下方に符号DW、車両用シート側方に符号Lを付す。
図1の車両用シート2は、シートクッション4と、シートバック6と、ヘッドレスト8を有する。これらシート構成部材は、各々、シート外形をなして乗員を弾性的に支持するクッション材(4P,6P,8P)と、クッション材を被覆する表皮材(4S,6S,8S)を有する。
Hereinafter, embodiments for carrying out the present invention will be described with reference to FIGS. In each drawing, reference numeral F is attached to the front of the vehicle seat, reference numeral B to the rear of the vehicle seat, reference numeral UP to the upper side of the vehicle seat, reference numeral DW to the lower side of the vehicle seat, and reference numeral L to the side of the vehicle seat.
The vehicle seat 2 in FIG. 1 has a seat cushion 4, a seat back 6, and a headrest 8. Each of these seat constituent members includes a cushion material (4P, 6P, 8P) that elastically supports an occupant by forming a seat outer shape, and a skin material (4S, 6S, 8S) that covers the cushion material.

本実施形態では、シートクッション4の表皮材4Sの一部が通電可能とされて、静電容量式センサの電極又はヒータとして機能する(図1〜図3を参照)。
ここで表皮材4S(布材の一例)は、複数の表皮ピースからなる部材であり、隣り合う表皮ピース同士(第一ピース40f,第二ピース40s等)を順次つなげることで作成できる。
そして第一ピース40f(詳細後述)は、通電可能な第一糸材11(導電糸21,22)と、第二糸材12を備える。この種の構成では、隣り合うピース40f,40s同士を性能良く(例えば導電糸の断線を極力回避しつつ)つなげられることが望ましい。
そこで本実施形態では、後述の構成にて、隣り合うピース40f,40s同士を性能良くつなげることとした。以下、各構成要素について詳述する。
In the present embodiment, a part of the skin material 4S of the seat cushion 4 can be energized, and functions as an electrode or a heater of the capacitive sensor (see FIGS. 1 to 3).
Here, the skin material 4S (an example of a cloth material) is a member composed of a plurality of skin pieces, and can be created by sequentially connecting adjacent skin pieces (first piece 40f, second piece 40s, etc.).
The first piece 40f (detailed later) includes a first thread material 11 (conductive threads 21 and 22) that can be energized and a second thread material 12. In this type of configuration, it is desirable that the adjacent pieces 40f and 40s can be connected with good performance (for example, while avoiding disconnection of the conductive yarn as much as possible).
Therefore, in the present embodiment, adjacent pieces 40f and 40s are connected with good performance in the configuration described later. Hereinafter, each component will be described in detail.

[表皮材(布材)]
表皮材4S(布材の一例)は、上述の通り、複数の表皮ピース(第一ピース40f,第二ピース40sなど)を有する(図1〜図3及び図5を参照)。
そして第一ピース40fは、シート中央(シートメイン部)形状に倣った略矩形の面材であり、第一糸材11と、第二糸材12と、接続部材30を有する(各糸材及び部材の構成は後述)。そして第一ピース40f(通電可能な面材)を電源9に電気的に接続することにより、静電容量式センサの電極やヒータとして機能させることができる。
また第二ピース40sは、シート側部形状に倣った形状の面材であり、布帛(布材,編物,不織布)、皮革(天然皮革,合成皮革)又はこれらの複合材にて形成できる。
[Skin material (cloth material)]
The skin material 4S (an example of a cloth material) has a plurality of skin pieces (first piece 40f, second piece 40s, etc.) as described above (see FIGS. 1 to 3 and 5).
The first piece 40f is a substantially rectangular face material following the sheet center (sheet main portion) shape, and includes a first thread material 11, a second thread material 12, and a connecting member 30 (each thread material and The structure of the member will be described later). Then, by electrically connecting the first piece 40f (surface material that can be energized) to the power source 9, the first piece 40f can function as an electrode or a heater of a capacitance sensor.
The second piece 40s is a face material having a shape that follows the shape of the side of the seat, and can be formed of fabric (cloth material, knitted fabric, non-woven fabric), leather (natural leather, synthetic leather), or a composite material thereof.

ここで各ピース40f,40sの裏面側(クッション材を臨む側)には、バッキング層(図示省略)と、パッド材14と、裏基布16を積層状に配設できる(図2及び図5を参照)。
バッキング層は、バッキング剤(樹脂)のコーティング層であり、各ピースのホツレを防止するために施される。またパッド材14は、例えば発泡ウレタンシートであり、各ピースの初期触感向上のために配設される。そして裏基布16は、例えばハーフトリコットの裏基布であり、その下に両ピース40f,40s同士をあわせる(つなげる)際のすべり改善のために配設される。
Here, a backing layer (not shown), a pad material 14, and a back base fabric 16 can be arranged in a laminated form on the back side (the side facing the cushion material) of each piece 40f, 40s (FIGS. 2 and 5). See).
The backing layer is a coating layer of a backing agent (resin) and is applied in order to prevent the pieces from fraying. The pad material 14 is, for example, a foamed urethane sheet, and is disposed to improve the initial tactile sensation of each piece. The back base fabric 16 is, for example, a half tricot back base fabric, and is disposed below the back base fabric 16 for improving slipping when the pieces 40f, 40s are joined (connected).

[第一糸材]
第一糸材11は、通電性を有する線材であり、第一ピース40fの構成糸として使用される(図2〜図4を参照)。
本実施形態の第一糸材11は、カバリング構造を有しており、芯糸20と、芯糸にスパイラル状に巻装される導電糸(21,22)を有する。このように第一糸材11をカバリング構造とすることで、第一糸材11に力がかかったとき、カバリング糸としての導電糸(21,22)に力がかかる前に芯糸20に負担させることができる(導電糸への負荷を軽減できる)。
[First thread material]
The first thread material 11 is a conductive wire and is used as a constituent thread of the first piece 40f (see FIGS. 2 to 4).
The first thread material 11 of the present embodiment has a covering structure, and includes a core thread 20 and conductive threads (21, 22) wound around the core thread in a spiral shape. Since the first thread material 11 has a covering structure in this way, when a force is applied to the first thread material 11, the core thread 20 is burdened before the force is applied to the conductive thread (21, 22) as the covering thread. (The load on the conductive yarn can be reduced).

(芯糸)
芯糸20は、紡績糸、フィラメント糸、延伸糸及び伸縮加工糸(仮撚加工糸や座屈糸)等の糸材である(図3を参照)。芯糸20として、複数の糸材を引き揃えるなどして使用することができ、また単数の糸材を使用することもできる。
芯糸20(材質)は特に限定しないが、植物系及び動物系の天然繊維、熱可塑性樹脂又は熱硬化性樹脂からなる化学繊維及びこれらの混繊糸を例示できる。
天然繊維では、綿、麻又は羊毛が風合いに優れるため、第一ピース40f(表皮材4S)の構成糸として用いることが好ましい。また化学繊維では、ポリエステル繊維(例えばポリエチレンテレフタレートのフィラメント)やナイロン繊維は耐久性と風合いと強度に優れるため、第一ピース40f(表皮材4S)の構成糸として用いることが好ましい。
(Core yarn)
The core yarn 20 is a thread material such as a spun yarn, a filament yarn, a drawn yarn, and an elastic yarn (false twisted yarn or buckling yarn) (see FIG. 3). The core yarn 20 can be used by arranging a plurality of yarn materials, or a single yarn material can be used.
The core yarn 20 (material) is not particularly limited, and examples thereof include plant-based and animal-based natural fibers, chemical fibers made of a thermoplastic resin or a thermosetting resin, and mixed fibers thereof.
In natural fibers, cotton, hemp or wool is excellent in texture, so that it is preferably used as a constituent yarn of the first piece 40f (skin material 4S). As chemical fibers, polyester fibers (for example, polyethylene terephthalate filaments) and nylon fibers are excellent in durability, texture and strength, and are therefore preferably used as constituent yarns of the first piece 40f (skin material 4S).

(導電糸)
導電糸(21,22)は、通電可能な導電性の線材であり、典型的に比抵抗(体積抵抗率とも呼ぶ)が10〜10−12Ω・cmである(図3を参照)。
ここで「比抵抗(体積抵抗率)」とは、どのような材料が電気を通しにくいかを比較するために用いられる物性値であり、例えば「JIS C2525 7.2.C 体積抵抗率」に準拠して測定できる。
この種の導電糸として、金属や合金などの糸材、メッキ線材、炭素繊維のフィラメントを例示できる。メッキ線材は、非導電性又は導電性の線材(芯材)と、金属又は合金のメッキ層を有する。また炭素繊維とは、ポリアクリロニトリル系炭素繊維(PAN系炭素繊維)やピッチ系炭素繊維である。なかでも焼成温度1000℃以上の炭素繊維(炭素化繊維、黒鉛化繊維、黒鉛繊維)のフィラメントは良好な電気伝導性を有するため、本実施形態の導電糸として好適に使用できる。
なお導電糸(21,22)は、単数の導電糸にて形成することができ、また複数の導電糸を撚り合せて形成することもできる。
(Conductive yarn)
The conductive yarns (21, 22) are conductive wires that can be energized, and typically have a specific resistance (also referred to as volume resistivity) of 10 0 to 10 −12 Ω · cm (see FIG. 3).
Here, the “specific resistance (volume resistivity)” is a physical property value used for comparing what kind of material is difficult to conduct electricity, for example, “JIS C2525 7.2.C volume resistivity”. It can be measured in compliance.
Examples of this type of conductive yarn include metal and alloy yarn materials, plated wire materials, and carbon fiber filaments. The plated wire has a non-conductive or conductive wire (core material) and a plated layer of metal or alloy. Carbon fibers are polyacrylonitrile-based carbon fibers (PAN-based carbon fibers) and pitch-based carbon fibers. Among them, filaments of carbon fibers (carbonized fibers, graphitized fibers, graphite fibers) having a firing temperature of 1000 ° C. or higher have good electrical conductivity, and can be suitably used as the conductive yarn of this embodiment.
The conductive yarns (21, 22) can be formed of a single conductive yarn, or can be formed by twisting a plurality of conductive yarns.

(第一糸材の作成)
図3を参照して、導電糸(21,22)を、芯糸20に対してスパイラル状に巻装することで第一糸材11を作成する。ここで第一糸材11中の導電糸の本数は特に限定しないが、典型的には1本(シングルカバリング)、2本(ダブルカバリング)等の偶数本に設定できる。
例えば本実施形態では、第一導電糸21をZ撚りにて巻装するとともに、第二導電糸22をS撚りにて巻装する(ダブルカバリングする)。このように各導電糸21,22(典型的に収縮しにくい糸材)を巻装することで、第一糸材11の収縮性が、第二糸材12(後述)よりも劣ることとなる。このとき第一導電糸21と第二導電糸22のカバリング方向を異ならせることで、第一糸材11の構造を安定化しつつ、第二糸材12(後述)との糸長差をより確実に発生させることができる。
なお第一導電糸21と第二導電糸22のいずれかを使用してシングルカバリングすることで、第一糸材11の部品点数を抑えて製造コスト等を低減することもできる。
(Create the first thread material)
Referring to FIG. 3, the first yarn material 11 is created by winding the conductive yarn (21, 22) around the core yarn 20 in a spiral shape. Here, the number of conductive yarns in the first yarn material 11 is not particularly limited, but can be typically set to an even number such as one (single covering) or two (double covering).
For example, in the present embodiment, the first conductive yarn 21 is wound with Z twist, and the second conductive yarn 22 is wound with S twist (double covering). By winding the conductive yarns 21 and 22 (typically yarn materials that are difficult to shrink) in this manner, the shrinkability of the first yarn material 11 is inferior to that of the second yarn material 12 (described later). . At this time, by making the covering directions of the first conductive yarn 21 and the second conductive yarn 22 different from each other, the structure of the first yarn material 11 is stabilized, and the yarn length difference from the second yarn material 12 (described later) is more reliably ensured. Can be generated.
In addition, by carrying out single covering using either the first conductive yarn 21 or the second conductive yarn 22, the number of parts of the first yarn material 11 can be suppressed and the manufacturing cost or the like can be reduced.

ここで導電糸(21,22)の撚数は、各導電糸の太さ(繊度)、フィラメント数(シングルカバリング、ダブルカバリング)などに応じて適宜設定できる。
例えばダブルカバリングの場合、第一導電糸21と第二導電糸22の撚数を、それぞれ独立に又は統一して200〜1500T/mの範囲に設定することで、第一糸材11に所望の強度を付与することができる。
第一導電糸21又は第二導電糸22の撚数が200T/m未満であると、各導電糸21,22が切断されるまでの伸度が十分得られない傾向にある。また第一導電糸21又は第二導電糸22の撚数が1500T/mより多いと、第一糸材11の剛性が高くなり、得られる第一ピース40fの風合いや触感が過度に悪化することがある。そして第一導電糸21と第二導電糸22の撚数を400〜1000T/mの範囲に設定することで、所望の性能を備えた第一糸材11とすることができる。
Here, the number of twists of the conductive yarns (21, 22) can be appropriately set according to the thickness (fineness) of each conductive yarn, the number of filaments (single covering, double covering), and the like.
For example, in the case of double covering, the number of twists of the first conductive yarn 21 and the second conductive yarn 22 can be set to a range of 200 to 1500 T / m independently or in a unified manner so that the first yarn material 11 has a desired number of twists. Strength can be imparted.
If the number of twists of the first conductive yarn 21 or the second conductive yarn 22 is less than 200 T / m, the elongation until each of the conductive yarns 21 and 22 is cut tends to be insufficient. Moreover, when the twist number of the 1st conductive yarn 21 or the 2nd conductive yarn 22 is more than 1500 T / m, the rigidity of the 1st thread | yarn material 11 will become high, and the texture and tactile sense of the 1st piece 40f obtained will deteriorate too much. There is. And it can be set as the 1st thread material 11 provided with the desired performance by setting the twist number of the 1st conductive thread 21 and the 2nd conductive thread 22 in the range of 400-1000 T / m.

[第二糸材]
第二糸材12は、第一糸材11よりも収縮しやすい糸材であり、紡績糸、フィラメント、延伸糸又は伸縮加工糸(仮撚加工糸や座屈糸)を例示できる(図2では、便宜上、個々の第二糸材12ではなく同糸材が使用される組織部分に符号を付す)。
そして第二糸材12(材質)として、植物系及び動物系の天然繊維、熱可塑性樹脂又は熱硬化性樹脂からなる化学繊維及びこれらの混繊維を例示できる。なかでも第二糸材12(材質)として、超音波による摩擦熱にて溶融可能な材質が好ましく、この種の材質として、ポリエステル繊維などの樹脂を例示できる。
なお第一糸材11と第二糸材12の糸長差は特に限定しないが、第二糸材12に対して第一糸材11が10%〜30%長いことが望ましい。両糸材の糸長差が10%未満であると、後述のように第一糸材11が蛇行状に配置しないおそれがある。また両糸材の糸長差が30%より大きいと、第二糸材12の収縮により第一糸材11が過度に引張されることがある。
[Second thread material]
The second yarn material 12 is a yarn material that is more easily contracted than the first yarn material 11, and can be exemplified by spun yarn, filament, drawn yarn, or stretchable yarn (false twisted yarn or buckled yarn) (in FIG. 2). For the sake of convenience, a reference numeral is given to the tissue portion in which the second yarn material 12 is used instead of the individual second yarn material 12).
Examples of the second thread material 12 (material) include plant-based and animal-based natural fibers, chemical fibers made of thermoplastic resin or thermosetting resin, and mixed fibers thereof. In particular, the second thread material 12 (material) is preferably a material that can be melted by frictional heat generated by ultrasonic waves. Examples of this type of material include resins such as polyester fibers.
The yarn length difference between the first thread material 11 and the second thread material 12 is not particularly limited, but it is desirable that the first thread material 11 is 10% to 30% longer than the second thread material 12. If the yarn length difference between the two yarn materials is less than 10%, the first yarn material 11 may not be arranged in a meandering manner as will be described later. If the difference in yarn length between the two yarn materials is greater than 30%, the first yarn material 11 may be excessively pulled due to the contraction of the second yarn material 12.

[第一ピースの作成]
図2を参照して、第一ピース40fを、第一糸材11と第二糸材12を使用しつつ作成する。
例えば織物としての第一ピース40fを作成する場合、経糸としての第二糸材12を整経したのち、緯糸としての第一糸材11を適宜打ち込むことができる。また経糸として、第一糸材11を使用することもできる。また編物(横編物等)としての第一ピース40fを作成する場合、コース方向又はウェール方向の一部に第一糸材11を導入することができる。そして第二糸材12にて布材としての布帛(織物,編物,不織布)を作成したのち、この布帛表面に第一糸材11を貼り付けたり、第一糸材11を配置した面材を貼り付けたりすることができる。
[Create the first piece]
Referring to FIG. 2, the first piece 40 f is created using the first thread material 11 and the second thread material 12.
For example, when creating the first piece 40f as a woven fabric, the first yarn material 11 as a weft can be appropriately driven after warping the second yarn material 12 as a warp. Moreover, the 1st thread material 11 can also be used as a warp. Moreover, when producing the 1st piece 40f as a knitted fabric (flat knitted fabric etc.), the 1st thread | yarn material 11 can be introduce | transduced into a part of a course direction or a wale direction. Then, after creating a fabric (woven fabric, knitted fabric, non-woven fabric) as a fabric material with the second thread material 12, the first thread material 11 is attached to the surface of the fabric, or the face material on which the first thread material 11 is arranged is used. It can be pasted.

本実施形態では、図4(a)の組織構成を参照して、織物の第一ピース40fを作成する。そして第一ピース40fのベースとなる部分を第二糸材(例えば経糸としての第二糸材12a〜12c、緯糸としての第二糸材12d〜12i)にて形成する。
このとき緯糸の一部に第一糸材11を使用して、ベース部分の幅方向に沿うように織り込む。そして第二糸材12a〜12iにて誘導点10a,10b及び拘束点10c(ともに後述)を形成することで、各第二糸材との収縮差により第一糸材11を蛇行状に配置することとした。
ここで第一糸材11と交差させる各第二糸材(誘導点及び拘束点を構成する糸材)は、第一ピース40fの表面意匠を構成する糸材でもよく、表面意匠とは無関係の糸材でもよい。例えば表面意匠とは無関係の(表面側に現れない)各第二糸材を誘導点(10a,10b)及び拘束点10cの形成に用いることで、第一糸材11の表面意匠への影響を極力排除できる。
In this embodiment, with reference to the structure | tissue structure of Fig.4 (a), the 1st piece 40f of a textile fabric is created. And the part used as the base of the 1st piece 40f is formed with the 2nd thread material (For example, the 2nd thread materials 12a-12c as a warp, The 2nd thread materials 12d-12i as a weft).
At this time, the first yarn material 11 is used for a part of the weft and is woven along the width direction of the base portion. Then, by forming induction points 10a, 10b and restraint points 10c (both described later) with the second thread materials 12a to 12i, the first thread material 11 is arranged in a meandering manner due to a contraction difference from each second thread material. It was decided.
Here, each of the second thread materials intersecting with the first thread material 11 (the thread material constituting the induction point and the restraint point) may be a thread material constituting the surface design of the first piece 40f, and is independent of the surface design. Yarn material may be used. For example, by using each second thread material unrelated to the surface design (not appearing on the surface side) for forming the induction points (10a, 10b) and the restraint points 10c, the influence on the surface design of the first thread material 11 is achieved. It can be eliminated as much as possible.

(誘導点)
誘導点(第一誘導点10a,第二誘導点10b)は、第一ピース40fの面方向に第一糸材11の変位を許容する部位であり、経糸一部(第二糸材12a,12c)で構成される(図4(a)を参照)。
ここで第二糸材12aと第二糸材12cは第一糸材11(緯糸)よりも外方に配置しており、第一ピース40f表面からの第一糸材11の飛び出しを規制できる。
そして第一誘導点10aは、経糸の延びる方向で見て、第一糸材11の一側(図4で見て上側)の糸飛ばし長さ(緯糸の飛ばし量)が、第一ピース40fの他の箇所に比べて大きい箇所である。また第二誘導点10bは、経糸の延びる方向で見て、第一糸材11の他側(図4で見て下側)の糸飛ばし長さが他の箇所に比べて大きい箇所である。
(Induction point)
The guide points (first guide point 10a, second guide point 10b) are portions that allow displacement of the first thread material 11 in the surface direction of the first piece 40f, and part of the warp yarn (second thread materials 12a, 12c). (See FIG. 4A).
Here, the second thread material 12a and the second thread material 12c are disposed outward from the first thread material 11 (weft), and the first thread material 11 can be prevented from protruding from the surface of the first piece 40f.
The first guide point 10a has a yarn skipping length (weft skipping amount) on one side (the upper side in FIG. 4) of the first yarn material 11 as viewed in the direction in which the warp extends. It is a location that is larger than other locations. Further, the second guide point 10b is a portion where the yarn skipping length on the other side (lower side in FIG. 4) of the first yarn material 11 is larger than the other portions when viewed in the direction in which the warp extends.

(拘束点)
拘束点10cは、第一ピース40fの面方向に第一糸材11の変位を許容する範囲が誘導点(10a,10b)よりも小さい部位である(図4(a)を参照)。
本実施形態の拘束点10cは、経糸他部(第二糸材12b)で構成されており、第一誘導点10aと第二誘導点10bの間に形成される。なお第二糸材12bは第一糸材11よりも外方に配置しており、第一ピース40f表面からの第一糸材11の飛び出しを規制できる。
そして本実施形態の拘束点10cは、経糸の延びる方向で見て、第一糸材11一側の糸飛ばし長さが第一誘導点10aよりも小さく、また第一糸材11他側の糸飛ばし長さが、第二誘導点10bよりも小さい箇所である。
(Restriction point)
The restraint point 10c is a part where the range allowing the displacement of the first thread material 11 in the surface direction of the first piece 40f is smaller than the guide points (10a, 10b) (see FIG. 4A).
The restraint point 10c of the present embodiment is composed of the warp other portion (second yarn material 12b) and is formed between the first induction point 10a and the second induction point 10b. In addition, the 2nd thread material 12b is arrange | positioned outward rather than the 1st thread material 11, and can control | jump out the 1st thread material 11 from the surface of the 1st piece 40f.
The constraint point 10c of the present embodiment has a yarn skipping length on one side of the first yarn material 11 smaller than the first induction point 10a when viewed in the direction in which the warp extends, and a yarn on the other side of the first yarn material 11 The flying length is a portion smaller than the second guiding point 10b.

ここで結束点10cと誘導点10a(10b)の間隔(一周期の長さ)は特に限定しないが、5〜30mm程度が好ましく、より好ましくは10〜25mmである。そして一周期の長さを5〜30mm程度に設定することで、第一糸材11(剛性に優れて蛇行しにくい導電糸)を好適に蛇行させることができる。
また隣り合う拘束点10cの間に、単数又は複数の誘導点(10a又は10b)を形成できる。ここで隣り合う拘束点10cの間の距離が広くなると第一糸材11が引っかかりやすくなるため、隣り合う拘束点10cの間に緯糸に対して複数本の誘導点となる経糸を配置してもよい。誘導点を複数形成する場合、各誘導点の糸飛ばし長さを同一とすることができ、また第一糸材11の蛇行の位置(振幅の幅)に合わせて、各誘導点の糸飛ばし長さを適宜変えてもよい。
Although the space | interval (length of one period) of the binding point 10c and the induction | guidance | derivation point 10a (10b) is not specifically limited here, About 5-30 mm is preferable, More preferably, it is 10-25 mm. By setting the length of one cycle to about 5 to 30 mm, it is possible to suitably meander the first thread material 11 (conductive thread that has excellent rigidity and is difficult to meander).
Further, one or a plurality of induction points (10a or 10b) can be formed between the adjacent restraint points 10c. Here, since the first yarn material 11 is easily caught when the distance between the adjacent restraint points 10c is increased, warp yarns serving as a plurality of guide points for the wefts may be arranged between the adjacent restraint points 10c. Good. When a plurality of induction points are formed, the yarn skipping length of each induction point can be the same, and the yarn skipping length of each induction point can be matched to the meandering position (amplitude width) of the first yarn material 11. The thickness may be changed as appropriate.

なお第一ピース40f中の第一糸材11の配置本数は特に限定しないが、各種機能を好適に発揮させるために、複数の第一糸材11を、所定間隔をあけつつ平行に配置することが好ましい(図2を参照)。
例えば第一ピース40fにヒータ機能を持たせる場合、第一糸材11同士の間隔寸法W1を1mm〜60mmに設定することができる。また第一ピース40fにセンサ(電極)機能を持たせる場合、第一糸材11同士の間隔寸法W1を60mmの範囲内に設定することが望ましい。第一糸材11同士の間隔寸法W1が60mmを超えると、第一ピース40fのセンサ機能が悪化(静電容量が低下)して電極として機能しないおそれがある。好ましくは第一糸材11の間隔寸法W1の上限値を30mmとすることで、第一ピース40fがより好適なセンサ機能(静電容量)を備える。
In addition, although the arrangement | positioning number of the 1st thread | yarn material 11 in the 1st piece 40f is not specifically limited, In order to exhibit various functions suitably, several 1st thread | yarn material 11 is arrange | positioned in parallel at predetermined intervals. Is preferred (see FIG. 2).
For example, when the first piece 40f is provided with a heater function, the interval dimension W1 between the first thread materials 11 can be set to 1 mm to 60 mm. When the first piece 40f is provided with a sensor (electrode) function, it is desirable to set the interval dimension W1 between the first thread materials 11 within a range of 60 mm. If the spacing dimension W1 between the first thread materials 11 exceeds 60 mm, the sensor function of the first piece 40f is deteriorated (capacitance is reduced) and may not function as an electrode. Preferably, the first piece 40f has a more suitable sensor function (capacitance) by setting the upper limit value of the interval dimension W1 of the first thread material 11 to 30 mm.

(仕上げ処理)
本実施形態では、第一ピース40fを作成したのち、所定の仕上げ処理を行うことができる。
この仕上げ処理として、精練工程と、染色工程と、熱セット工程と、風合い出し工程と、後加工剤付与工程と、仕上げセット工程を例示でき、これら上述の工程を全て行うこともでき、1又は複数の工程を省略することもできる。
上記各工程では、第一ピース40fに熱処理(乾熱処理又は湿熱処理)を施すことが多く、例えば精練や染色工程では90〜155℃前後の熱処理が施されることが多い。そしてこの加熱処理によって、第一ピース40f中の各第二糸材が面方向に収縮する。また熱処理のほかに化学的な薬品による処理にて、各第二糸材が面方向に収縮することもある。なお第一ピース40fの収縮により、織物の地厚感や伸び付与、仕立て栄えにも効果がある。
(Finishing process)
In the present embodiment, a predetermined finishing process can be performed after the first piece 40f is created.
Examples of the finishing treatment include a scouring step, a dyeing step, a heat setting step, a texture-out step, a post-processing agent application step, and a finishing setting step, and all of the above-described steps can be performed. A plurality of steps can be omitted.
In each of the above steps, the first piece 40f is often subjected to heat treatment (dry heat treatment or wet heat treatment). For example, in the scouring or dyeing step, heat treatment at around 90 to 155 ° C. is often performed. And by this heat processing, each 2nd thread material in the 1st piece 40f shrink | contracts in a surface direction. In addition to heat treatment, the second yarn material may shrink in the surface direction by treatment with a chemical agent. Note that the shrinkage of the first piece 40f is effective in providing a sense of fabric thickness, imparting elongation, and tailoring.

本実施形態では、上述の仕上げ処理において、各第二糸材が相対的に収縮することで、第一糸材11(収縮性に劣る糸材)が蛇行状に撓み変形する。
このとき第一糸材11が、拘束点10cにて拘束された箇所を支点として、誘導点10a,10bにおいて山なりに撓み変形する。すなわち第一糸材11が、第一誘導点10aに沿って一側(図4で見て上側)に向けて山なりに撓み変形するとともに、第二誘導点10bに沿って他側(図4で見て下側)に向けて山なりに撓み変形する。
このように本実施形態では、誘導点10a,10bと拘束点10cなどにて、第一糸材11を面方向にスムーズに蛇行させることにより、第一ピース40fからの第一糸材11の飛び出しを極力阻止できる。
In the present embodiment, in the above-described finishing process, the second thread material relatively contracts, whereby the first thread material 11 (the thread material inferior in contractibility) is bent and deformed in a meandering manner.
At this time, the first thread material 11 bends and deforms in a mountain shape at the guide points 10a and 10b, with the portion restrained at the restraint point 10c as a fulcrum. That is, the first thread material 11 is bent and deformed in a mountain-like manner toward the one side (upper side in FIG. 4) along the first induction point 10a, and the other side (FIG. 4) along the second induction point 10b. Deforms and deforms like a mountain toward the lower side.
As described above, in the present embodiment, the first thread material 11 jumps out of the first piece 40f by smoothly meandering the first thread material 11 in the surface direction at the guide points 10a and 10b and the restraint point 10c. Can be prevented as much as possible.

[表皮材(布材)の作成作業]
図2及び図4を参照して、第一ピース40fの向きを調節するなどして、第一糸材11をシート幅方向に向けつつ配置する。
そして本実施形態では、第一ピース40fと、第二ピース40s(専ら第二糸材12からなる面材)を表面で接するように重ね合わせたのち、シート幅方向でみた第一ピースの側部(第一ピースの一部)を第二ピース40sの側部につなげる。そして両ピース40f,40sをつなげたのち、つなげた部分(つなぎ目)を基準として両ピースを内折り状に拡開させる(図5を参照)。
この種の構成では、隣り合うピース40f,40s同士を性能良く(例えば導電糸の断線を極力回避しつつ)つなげられることが望ましい。
[Creation work of skin material (cloth material)]
With reference to FIGS. 2 and 4, the first thread material 11 is arranged in the sheet width direction by adjusting the direction of the first piece 40 f.
In the present embodiment, the first piece 40f and the second piece 40s (a face material made exclusively of the second thread material 12) are overlapped so as to contact each other on the surface, and then the side portion of the first piece as viewed in the sheet width direction. (Part of the first piece) is connected to the side of the second piece 40s. Then, after connecting both pieces 40f and 40s, both pieces are expanded in an inwardly folded manner with reference to the connected portion (joint) (see FIG. 5).
In this type of configuration, it is desirable that the adjacent pieces 40f and 40s can be connected with good performance (for example, while avoiding disconnection of the conductive yarn as much as possible).

そこで本実施形態では、第一ピース40fの一部を第二ピース40sに溶着又は接着(後述)にてつなげることとした。
例えば図5(a)を参照して、第一ピース40fと第二ピース40sを重ね合わせて(側部同士を接触させて)、これらの側部に超音波を当ててピース表面同士を擦り合わせる。この擦り合わせにより各ピースの構成要素(専ら第二糸材12)を溶融させたのち固化させる(溶着部分CPを形成する)ことで、両ピース40f,40sをつなげることができる。
このように第一ピース40fと第二ピース40sを溶着にてつなげる(ミシンを用いずにつなげる)ことで、導電糸21,22の断線を極力阻止できる。そして溶着部分CPを、両ピース40f,40sの重なる部位全部に連続的に形成することで、これらピースの間に隙間(液体の侵入可能な隙間)が生ずることを極力阻止できる。
なお溶融方法は、超音波のほか、熱的な作用を加える各種の方法を取り得る。
Therefore, in the present embodiment, a part of the first piece 40f is connected to the second piece 40s by welding or bonding (described later).
For example, referring to FIG. 5A, the first piece 40f and the second piece 40s are overlapped (with the side portions in contact with each other), and ultrasonic waves are applied to these side portions to rub the piece surfaces together. . Both pieces 40f and 40s can be connected by melting the constituent elements (exclusively the second thread material 12) of each piece by this rubbing and then solidifying (forming the welded portion CP).
Thus, by disconnecting the first piece 40f and the second piece 40s by welding (connecting them without using a sewing machine), it is possible to prevent disconnection of the conductive yarns 21 and 22 as much as possible. Then, by continuously forming the welded portion CP in all the overlapping portions of both pieces 40f and 40s, it is possible to prevent as much as possible that a gap (a gap through which liquid can enter) is generated between these pieces.
As the melting method, various methods of applying a thermal action can be taken in addition to ultrasonic waves.

(連結材)
ここで連結材CMを用いて、第一ピース40fと第二ピース40sを溶着にてつなげることもできる(図5(b)を参照)。連結材CMは、第一ピース40f及び第二ピース40sよりも熱で溶けやすい部材であり、低融点の面材や線材を例示できる。
この種の連結材CM(材質)として、ポリアミド系樹脂、ポリエステル系樹脂、ポリエチレン系樹脂、オレフィン系樹脂を例示でき、融点が100℃以上の樹脂であることが好ましい。なかでも低融点ポリエステル製の不織布(面材)は接着強度に優れるため、低融点の面材として用いることが好ましい。
そして連結材CMの融点は、第一ピース40fと第二ピース40sの構成要素を考慮して適宜設定可能であり、他の構成要素(特に第二糸材12や芯糸20)よりも20℃以下であることが望ましい。例えばポリエチレンテレフタレートを他の構成要素(第二糸材12等)の材質として使用する場合、連結材CMの融点を100℃〜240℃の範囲に設定できる。
(Connecting material)
Here, the first piece 40f and the second piece 40s can be connected by welding using the connecting material CM (see FIG. 5B). The connecting material CM is a member that is more easily melted by heat than the first piece 40f and the second piece 40s, and examples thereof include a low melting point surface material and a wire.
Examples of this type of connecting material CM (material) include polyamide resins, polyester resins, polyethylene resins, and olefin resins, and resins having a melting point of 100 ° C. or higher are preferable. Among these, a low melting point polyester non-woven fabric (face material) is excellent in adhesive strength, and is preferably used as a low melting point face material.
The melting point of the connecting material CM can be appropriately set in consideration of the components of the first piece 40f and the second piece 40s, and is 20 ° C. than other components (particularly the second yarn material 12 and the core yarn 20). The following is desirable. For example, when polyethylene terephthalate is used as a material for other components (second thread material 12 or the like), the melting point of the connecting material CM can be set in the range of 100 ° C to 240 ° C.

そして図5(b)を参照して、連結材CM(低融点の面材等)を、第一ピース40fの一部と第二ピース40sの間に介装する(両ピースの間に挟む)。つぎに超音波等を用いて連結材CMを溶融固化させることにより、両ピース40f,40sを溶着にてつなげることができる。このように連結材CMを用いることで、各ピース40f,40s自体を極力溶融させることなく(強度低下を回避しつつ)、両ピースをつなげることができる。
このとき第一ピース40fと第二ピース40sの連結箇所に沿って連結材CMを連続的に配置することが好ましい。こうすることで第一ピース40fと第二ピース40sを連結材CMにて密着状につなげることができ、各ピースの間に隙間(液体の侵入可能な隙間)が生ずることを極力阻止できる。
なお連結材は、各ピースの構成要素の間(バッキング層とパッド材14と裏基布16のいずれかの間)に介装することもできる(図2及び図5を参照)。この場合には連結材が溶融しつつ、各ピース表面側に浸潤したのち(両ピースに挟まれた状態で)固化することにより、両ピース40f,40sをつなげることとなる。
And with reference to FIG.5 (b), connecting material CM (surface material etc. of low melting | fusing point) is interposed between the part of the 1st piece 40f, and the 2nd piece 40s (it pinches | interposes between both pieces). . Next, both pieces 40f and 40s can be connected by welding by melting and solidifying the connecting material CM using ultrasonic waves or the like. By using the connecting material CM in this way, both pieces can be connected without melting each piece 40f, 40s itself as much as possible (while avoiding strength reduction).
At this time, it is preferable to continuously arrange the connecting material CM along the connecting portion of the first piece 40f and the second piece 40s. By doing so, the first piece 40f and the second piece 40s can be connected in close contact with the connecting material CM, and the occurrence of a gap (a gap through which liquid can enter) between each piece can be prevented as much as possible.
In addition, a connection material can also be interposed between the components of each piece (between the backing layer, the pad material 14, and the back base fabric 16) (refer FIG.2 and FIG.5). In this case, both pieces 40f and 40s are connected by solidifying (in a state sandwiched between both pieces) after infiltrating the surface of each piece while the connecting material is melted.

(接着剤)
また接着剤(図示省略)を用いて、第一ピース40fと第二ピース40sを接着にてつなげることもできる。例えば図5(b)を参照して、連結材CMの代わりに接着剤を介装したのち圧着する(圧力を加えつつ接着する)ことで、両ピース40f,40sを接着にてつなげることができる。
この種の接着剤として、ウレタン系樹脂(シリル化ウレタン樹脂等)、アクリル系樹脂、アミノプラスト樹脂、エポキシ樹脂、グリオキザール系樹脂及びエチレン尿素樹脂を例示できる。例えば接着剤として、風合い及び耐久性に優れるウレタン系樹脂又はアクリル系樹脂を使用することが好ましい。
(adhesive)
Alternatively, the first piece 40f and the second piece 40s can be bonded together using an adhesive (not shown). For example, referring to FIG. 5 (b), both pieces 40f and 40s can be connected by bonding by interposing an adhesive instead of the connecting material CM and then pressing (bonding while applying pressure). .
Examples of this type of adhesive include urethane resins (such as silylated urethane resins), acrylic resins, aminoplast resins, epoxy resins, glyoxal resins, and ethylene urea resins. For example, as the adhesive, it is preferable to use a urethane resin or an acrylic resin that is excellent in texture and durability.

(引張強さ)
ここで両ピース40f,40s(織物)のつなぎ目における引張強さは実用に耐える限り特に限定しない。例えば引張強度を、後述の実施例1に記載の条件の下、経100N〜700N、緯100N〜700N、バイアス(布目に対して斜め45°の方向)200N〜1300Nに設定することで実用性に優れる布材(表皮材4S)となる。
さらに同条件の下、経200N以上、緯200N以上、バイアス300N以上に設定することで、縫合によるつなぎ目と遜色のない引張強さを有する布材(表皮材4S)とすることができる。
なお上記引張強さは、「JIS L 1093 7.1.1 グラブ法 標準時縫目引張強さ」に順じて測定でき、このとき、掴み間隔を7.6cm、引張速度を30cm/mmに設定する。
(Tensile strength)
Here, the tensile strength at the joint of both pieces 40f, 40s (woven fabric) is not particularly limited as long as it can withstand practical use. For example, it is practical by setting the tensile strength to warp 100N to 700N, weft 100N to 700N, and bias (in the direction of 45 ° oblique to the cloth) 200N to 1300N under the conditions described in Example 1 described later. It becomes an excellent cloth material (skin material 4S).
Furthermore, by setting the warp 200N or more, the weft 200N or more, and the bias 300N or more under the same conditions, it is possible to obtain a cloth material (skin material 4S) having a tensile strength comparable to a joint by stitching.
The tensile strength can be measured according to “JIS L 1093 7.1.1 Grab Method Standard Seam Tensile Strength”. At this time, the grip interval is set to 7.6 cm and the tensile speed is set to 30 cm / mm. To do.

[接続部材]
上述の作業に前後して、第一ピース40fに接続部材30(帯状の布体)を配設する(図2及び図5を参照)。
ここで接続部材30は、導電糸(21,22)と電源9を電気的につなげる部材であり、導線等の線材、導電テープ、導電化された布体を例示できる。
本実施形態では、接続部材30を、第一ピース40fの両側端部(第一ピース40fの一部よりも端部寄りの他部)にそれぞれ取付けつつ、導電糸(21,22)の両端に電気的につなげる。このように接続部材30を、両ピースのつなぎ目(溶着部分CP等)よりも端部側に配置することで、表皮材4Sの性能(屈曲耐久性等)を好適に維持することができる。
そして一対の接続部材30を、電源ケーブル9aを介して電源9につなげることで、第一ピース40fを通電可能状態とすることができる。こうすることで表皮材4Sを、例えばヒータとして機能させることができる(利便性に優れるシート構成となる)。
[Connecting member]
Before and after the above operation, the connecting member 30 (band-shaped cloth body) is disposed on the first piece 40f (see FIGS. 2 and 5).
Here, the connection member 30 is a member that electrically connects the conductive yarns (21, 22) and the power source 9, and examples thereof include a wire such as a conductive wire, a conductive tape, and a conductive cloth body.
In the present embodiment, the connecting member 30 is attached to both ends of the first piece 40f (the other part closer to the end than the part of the first piece 40f), while being attached to both ends of the conductive yarn (21, 22). Connect electrically. Thus, the performance (bending durability etc.) of the skin material 4S can be suitably maintained by arranging the connection member 30 on the end side from the joint (welded portion CP etc.) of both pieces.
And a 1st piece 40f can be made into an energizable state by connecting a pair of connecting member 30 to the power supply 9 via the power cable 9a. By doing so, the skin material 4S can be made to function as, for example, a heater (a sheet configuration having excellent convenience).

(表皮材の使用)
図1、図2及び図5を参照して、表皮材4S(両ピース40f,40s)を、クッション材4P上に配置しつつ、ヒータ等として使用する。
本実施形態では、隣り合うピース40f,40s同士を溶着又は接着にてつなげることで、表皮材4S(各ピース)にダメージを極力与えない構成である。このため表皮材4Sの本来の性能(耐久性や意匠性)を好適に維持できるとともに、導電糸(21,22)の断線を回避することで、表皮材4Sのヒータ等としての機能を好適に維持できる。
また本実施形態では、第一ピース40fと第二ピース40sの間(つなぎ目)に隙間が極力生じない構成であるため、つなぎ目から液体が侵入することを極力阻止できる。このため本実施形態によれば、液体との接触が原因の導電糸(21,22)と接続部材30の変質(錆付きや電気分解など)を好適に阻止できる(耐久性に優れる構成となる)。
そして本実施形態では、第一糸材11が表皮材4Sに蛇行状に配置する。このため表皮材4Sの幅方向に力が加わったときでも第一糸材11(蛇行状)が直線となるように変形することで表皮材4Sが力を負担し、第一糸材11に過度の力が加わらず断線を抑制できる。
この結果として本実施形態によれば、隣り合うピース40f,40s同士を性能良くつなげることができる。
(Use of skin material)
With reference to FIGS. 1, 2 and 5, the skin material 4S (both pieces 40f, 40s) is used as a heater or the like while being disposed on the cushion material 4P.
In this embodiment, it is the structure which does not give damage to the skin material 4S (each piece) as much as possible by connecting adjacent pieces 40f and 40s by welding or adhesion | attachment. Therefore, the original performance (durability and design) of the skin material 4S can be suitably maintained, and the function of the skin material 4S as a heater or the like is suitably avoided by avoiding disconnection of the conductive yarns (21, 22). Can be maintained.
Moreover, in this embodiment, since it is the structure which does not produce a clearance gap as much as possible between the 1st piece 40f and the 2nd piece 40s (joint), it can prevent that a liquid penetrate | invades from a joint as much as possible.
