Description

本発明は、導電線材と接続部材を有する布材の製造方法に関する。   The present invention relates to a method for manufacturing a cloth material having a conductive wire and a connecting member.

この種の布材として特許文献１の織物が公知である。この織物は、ヒータとして使用可能であり、主構成としての他の線材（絶縁繊維などの非導電糸）と、導電線材と、導電線材に電力を供給可能な接続部材を有する。導電線材は、通電により発熱可能な導電糸であり、金属、合金、導電性プラスチック又は炭素繊維にて構成される。
そして公知技術では、経糸又は緯糸の大部分に非導電糸を用いるとともに、これら糸の一部に導電線材を用いて織物を織製する。つぎに接続部材を織物に熱溶着又は貼着する（接続作業を行う）ことで、導電線材と接続部材を電気的につなげることができる。 As this type of fabric material, the woven fabric of Patent Document 1 is known. This woven fabric can be used as a heater, and has another wire (non-conductive yarn such as insulating fiber) as a main configuration, a conductive wire, and a connecting member capable of supplying power to the conductive wire. The conductive wire is a conductive yarn that can generate heat when energized, and is made of metal, alloy, conductive plastic, or carbon fiber.
And in a well-known technique, while using a nonelectroconductive thread | yarn for the most part of a warp or a weft, a textile fabric is woven using a conductive wire for a part of these thread | yarns. Next, the conductive wire and the connection member can be electrically connected by thermally welding or sticking the connection member to the fabric (performing a connection operation).

特開２００７−２２７３８４号公報JP 2007-227384 A

しかし公知技術では、織物の主構成である非導電糸が、導電線材と接続部材の接触の邪魔となるなどして、両者の接続性が悪化することがあった。
もっとも他の線材を除去すればよいが、そうすると支えを失った導電糸が湾曲などして、他の導電糸と混線しやすくなる（接続作業に手間取る構成となる）。
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、より簡単な接続作業によって、接続部材と導電線材を接続性良く電気的につなげることにある。 However, in the known technique, the non-conductive yarn, which is the main component of the woven fabric, may interfere with the contact between the conductive wire and the connection member, and the connectivity between the two may deteriorate.
However, the other conductive material may be removed, but the conductive yarn that has lost its support is bent and is easily mixed with the other conductive yarn (having a structure that requires time for connection work).
The present invention has been devised in view of the above points, and a problem to be solved by the present invention is to electrically connect the connection member and the conductive wire with good connectivity by a simpler connection operation.

上記課題を解決するための手段として、第１発明の布材の製造方法は、通電可能な導電線材と、導電線材に電力を供給可能な接続部材とを備える布材の製造方法である。
そしてこの種の布材では、より簡単な接続作業によって、接続部材と導電線材を接続性良く電気的につなげられることが望ましい。
そこで本発明では、布材の一部を導電線材で構成するとともに、一部とは異なる布材の他部を、導電線材よりも脆弱な他の線材（強度の低い線材、溶融しやすい線材、燃焼しやすい線材、耐薬品性に劣る線材等）にて構成する。 As a means for solving the above-mentioned problems, a method for manufacturing a cloth material according to a first aspect of the present invention is a method for manufacturing a cloth material including a conductive wire material that can be energized and a connection member that can supply power to the conductive wire material.
In this type of cloth material, it is desirable that the connecting member and the conductive wire can be electrically connected with good connectivity by a simpler connecting operation.
Therefore, in the present invention, a part of the cloth material is made of a conductive wire, and the other part of the cloth material different from the part is made of another wire that is weaker than the conductive wire (low-strength wire, easy-to-melt wire, Wires that are easy to burn, wires that are inferior in chemical resistance, etc.).

そして下記の２工程によって、導電線材と接続部材を電気的につなげることとした。
第１工程：分割手段によって他の線材を布材から除去して、布材本体と布材片に分割することにより、両者の間の分割部（分断部や分割孔部）から導電線材を露出させる。
第２工程：布材本体と布材片によって、複数の導電線材の相対位置関係を維持しつつ、分割部から露出した複数の導電線材に接続部材を電気的につなげる。
本発明では、上述の布材片を、露出した導電線材（被接続部分）を固定するための冶具として使用する構成（比較的シンプルな構成）である。そしてこの構成によって、複数の導電線材の相対位置関係を維持することにより、各導電線材を極力混線させることなく接続部材と電気的につなげることができる。 Then, the conductive wire and the connecting member are electrically connected by the following two steps.
1st process: The other wire is removed from the cloth material by the dividing means and divided into the cloth material main body and the cloth material piece, so that the conductive wire is exposed from the divided portion (divided portion or divided hole) between the two. Let
Second step: The connecting member is electrically connected to the plurality of conductive wires exposed from the divided portion while maintaining the relative positional relationship of the plurality of conductive wires by the cloth body and the cloth pieces.
In this invention, it is the structure (relatively simple structure) which uses the above-mentioned cloth material piece as a jig for fixing the exposed electrically conductive wire (connected part). And by this structure, by maintaining the relative positional relationship of a some conductive wire, it can electrically connect with a connection member, without causing each conductive wire to mix as much as possible.

第２発明の布材の製造方法は、第１発明に記載の布材の製造方法であって、第３工程において、上述の布材片で接続部材を覆う（保護する）こととした。
本発明では、接続部材を布材片で保護することにより、運搬時や使用時における接続部材の破損等を防止又は低減して、布材の耐久性を向上させることができる。 The cloth material manufacturing method according to the second invention is the cloth material manufacturing method according to the first invention, and in the third step, the connecting member is covered (protected) with the above-mentioned cloth material piece.
In the present invention, by protecting the connecting member with the piece of cloth material, damage or the like of the connecting member during transportation or use can be prevented or reduced, and the durability of the cloth material can be improved.

本発明に係る第１発明によれば、より簡単な接続作業によって、接続部材と導電線材を接続性良く電気的につなげることができる。そして第２発明によれば、布材の構成要素を有効利用して、布材の耐久性を向上させることができる。   According to the first aspect of the present invention, the connection member and the conductive wire can be electrically connected with good connectivity by a simpler connection operation. And according to 2nd invention, the durability of a cloth material can be improved by utilizing the component of a cloth material effectively.

以下、本発明を実施するための形態を、図１〜図７を参照して説明する。各図では、便宜上、一部の導電線材にのみ符号を付すことがある。
そして各図には、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を付す。 Hereinafter, embodiments for carrying out the present invention will be described with reference to FIGS. In each figure, a code | symbol may be attached | subjected only to one part conductive wire for convenience.
In each of the drawings, a reference symbol F is attached to the front of the vehicle seat, a reference symbol B is attached to the rear of the vehicle seat, a reference symbol UP is provided above the vehicle seat, and a reference symbol DW is provided below the vehicle seat.

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。これら部材は、各々、シート外形をなすクッション材（４Ｐ，６Ｐ，８Ｐ）と、表皮材（４Ｓ，６Ｓ，８Ｓ）を有する（図４を参照）。
そして各実施形態では、シートクッション４の表皮材４Ｓが、複数の導電線材２０を備える布材１０（詳細後述）にて構成されている（図２を参照）。この布材１０は、複数の導電線材２０に接続部材３０を電気的につなげることで、静電容量式センサの電極又はヒータとして機能するのであるが、このとき導電線材２０と接続部材３０を接続性良くつなげることが望まれる（図３を参照）。
そこで各実施形態では、後述する各工程（簡単な接続作業）によって、接続部材３０と導電線材２０を接続性良く電気的につなげることとした。 A vehicle seat 2 in FIG. 1 includes a seat cushion 4, a seat back 6, and a headrest 8. Each of these members has a cushion material (4P, 6P, 8P) and an outer skin material (4S, 6S, 8S) forming the outer shape of the seat (see FIG. 4).
And in each embodiment, the skin material 4S of the seat cushion 4 is comprised by the cloth material 10 (it mentions details later) provided with the some conductive wire 20 (refer FIG. 2). The cloth material 10 functions as an electrode or a heater of a capacitive sensor by electrically connecting the connection member 30 to the plurality of conductive wire materials 20. At this time, the conductive wire material 20 and the connection member 30 are connected. It is desirable to connect them with good performance (see FIG. 3).
Therefore, in each embodiment, the connection member 30 and the conductive wire 20 are electrically connected with good connectivity by each step (simple connection work) described later.

＜実施形態１＞
本実施形態では、表皮材４Ｓとしての布材１０を作製（前工程）したのち、下記の２工程によって接続部材３０と導電線材２０を電気的につなげる（図２及び図３を参照）。
第１工程：分割手段によって他の線材を布材１０から除去して、布材本体１０ｂと布材片１０ｆに分割する。そして布材本体１０ｂと布材片１０ｆの間の分断部２２ａ（分割部の一例）から導電線材２０を露出させる。
第２工程：布材本体１０ｂと布材片１０ｆによって、複数の導電線材２０の相対位置関係を維持しつつ、分断部２２ａから露出した複数の導電線材２０に接続部材３０を電気的につなげる。 <Embodiment 1>
In this embodiment, after producing the cloth material 10 as the skin material 4S (pre-process), the connecting member 30 and the conductive wire material 20 are electrically connected by the following two processes (see FIGS. 2 and 3).
First step: The other wire material is removed from the cloth material 10 by the dividing means and divided into the cloth material body 10b and the cloth material piece 10f. And the conductive wire 20 is exposed from the parting part 22a (an example of a division | segmentation part) between the cloth material main body 10b and the cloth material piece 10f.
Second step: The connecting member 30 is electrically connected to the plurality of conductive wire members 20 exposed from the dividing portion 22a while maintaining the relative positional relationship of the plurality of conductive wire members 20 by the cloth material body 10b and the cloth material piece 10f.

［前工程］
前工程では、導電線材２０と他の線材を用いて布材１０を作製する。この布材１０は、織物、編物及び不織布のいずれでもよい。
また後述するように、表皮材４Ｓとして布材１０を用いる場合には、適宜パッド材１２や裏基布を用いることができる（図４を参照）。以下、各構成について詳述する。 [pre-process]
In the pre-process, the fabric material 10 is produced using the conductive wire 20 and another wire. The fabric material 10 may be a woven fabric, a knitted fabric, or a non-woven fabric.
As will be described later, when the cloth material 10 is used as the skin material 4S, a pad material 12 or a back base cloth can be used as appropriate (see FIG. 4). Hereinafter, each configuration will be described in detail.

（他の線材）
他の線材は、導電線材２０（後述）よりも脆弱な線材であり、布材１０の主構成として使用することができる（図２を参照）。例えば他の線材は、導電線材２０と比較して、強度の低い線材、溶融しやすい線材、燃焼しやすい線材又は耐薬品性に劣る線材であることが望ましい。
上記他の線材（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紡繊維を例示できる。そして絶縁繊維の線材（フィラメントや紡績糸等）を布材１０の構成として使用することができる。 (Other wire)
The other wire is a wire more fragile than the conductive wire 20 (described later), and can be used as the main configuration of the cloth material 10 (see FIG. 2). For example, the other wire is desirably a wire having a low strength, a wire that is easily melted, a wire that is easily combusted, or a wire that is inferior in chemical resistance as compared with the conductive wire 20.
Examples of the other wire (material) include plant-based and animal-based natural fibers, chemical fibers made of a thermoplastic resin or a thermosetting resin, and blended fibers thereof. An insulating fiber wire (filament, spun yarn, or the like) can be used as the structure of the cloth material 10.

上述の絶縁繊維の多くは、導電線材２０よりも脆弱である（例えば強度に劣る）。
また一般的な天然繊維は、導電線材２０よりも燃焼しやすい。そして天然繊維の主成分であるタンパク質は、タンパク質分解酵素や変性剤（酸や塩基）などの薬剤によって比較的簡単に分解又は脆弱化することができる。
そして一般的な化学繊維は、導電線材２０よりも低融点であるか又は燃焼しやすい傾向にある。また化学繊維は、有機溶剤などの薬剤によって比較的簡単に溶解又は脆弱化することができる。 Many of the above-described insulating fibers are more fragile than the conductive wire 20 (for example, inferior in strength).
Further, general natural fibers are easier to burn than the conductive wire 20. And the protein which is the main component of natural fiber can be decomposed or weakened relatively easily by drugs such as proteolytic enzymes and denaturing agents (acids and bases).
The general chemical fiber has a lower melting point than the conductive wire 20 or tends to burn easily. Chemical fibers can be dissolved or weakened relatively easily by chemicals such as organic solvents.

（導電線材）
導電線材２０は、通電可能な導電性の線材である（図２を参照）。この導電線材２０を布材１０に取付けることで、布材１０自体を、静電容量式センサの電極やヒータとして用いることができる。
上述の導電線材２０として、金属や合金などの導電糸、炭素繊維のフィラメント及びメッキされた非導電糸（メッキ線材）を例示できる。
ここで炭素繊維とは、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）は良好な電気伝導性を有するため、本実施形態の導電線材２０として好適に使用できる。 (Conductive wire)
The conductive wire 20 is a conductive wire that can be energized (see FIG. 2). By attaching the conductive wire material 20 to the cloth material 10, the cloth material 10 itself can be used as an electrode or a heater of a capacitive sensor.
Examples of the conductive wire 20 include conductive yarns such as metals and alloys, carbon fiber filaments, and plated non-conductive yarns (plated wires).
Here, the carbon fibers are polyacrylonitrile-based carbon fibers (PAN-based carbon fibers) and pitch-based carbon fibers. Among these, 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 wire 20 of the present embodiment.

そして導電線材２０は、他の線材よりも高強度の線材、高融点の線材、燃焼しにくい線材又は耐薬品性の高い線材であることが好ましい。例えば金属、合金又は炭素繊維の導電線材２０はいずれも剛性に優れ、上述の絶縁繊維よりも高強度であることが多い。
また導電糸やメッキ線材は、典型的に絶縁繊維よりも高融点であるか、または絶縁繊維よりも燃焼しにくい傾向にある。そして導電糸やメッキ線材は、典型的なタンパク質分解酵素や樹脂の溶解薬剤に耐性を有する。
そして炭素繊維（ＰＡＮ系炭素繊維及びピッチ系炭素繊維）は、非溶融性であるとともに、典型的に天然繊維や合成繊維よりも燃焼しにくい。また炭素繊維は、典型的なタンパク質分解酵素や樹脂の溶解薬剤に耐性を有する。 And it is preferable that the conductive wire 20 is a wire rod with a higher strength than other wires, a wire with a high melting point, a wire that is difficult to burn, or a wire with high chemical resistance. For example, the conductive wire 20 made of metal, alloy, or carbon fiber is excellent in rigidity and often has higher strength than the above-described insulating fiber.
Conductive yarns and plated wires typically have a higher melting point than insulating fibers or tend to be less flammable than insulating fibers. Conductive yarns and plated wire materials are resistant to typical proteolytic enzymes and resin dissolving agents.
Carbon fibers (PAN-based carbon fibers and pitch-based carbon fibers) are not meltable and are typically less flammable than natural fibers or synthetic fibers. Carbon fibers are resistant to typical proteolytic enzymes and resin dissolution drugs.

（布材の作製）
本実施形態では、布材１０の一部を複数の導電線材２０で構成する。そして布材１０の他部を、導電線材２０よりも脆弱な他の線材にて構成する。ここで複数の導電線材２０を、布材１０上に並列して配置させることが好ましい。例えば導電線材２０は、直線状又は波状として布材１０に配置する。
なお導電線材２０同士の間隔寸法（Ｗ１）は特に限定しないが、典型的には５ｍｍ〜５０ｍｍに設定することができる。ここで間隔寸法（Ｗ１）を５ｍｍ未満としてもよいが、導電線材２０の数が必要以上に増加してコスト高となる。また間隔寸法（Ｗ１）を５０ｍｍよりも長く設定すると、布材１０中の導電線材２０がまばら（疎ら）となり、センサ機能やヒータ機能の悪化を招きやすい。 (Production of fabric material)
In the present embodiment, a part of the cloth material 10 is composed of a plurality of conductive wires 20. And the other part of the fabric material 10 is comprised with the other wire material weaker than the conductive wire 20. FIG. Here, it is preferable to arrange the plurality of conductive wires 20 in parallel on the cloth material 10. For example, the conductive wire 20 is disposed on the cloth material 10 as a straight line or a wave.
In addition, although the space | interval dimension (W1) between the conductive wire materials 20 is not specifically limited, Typically, it can set to 5 mm-50 mm. Here, the interval dimension (W1) may be less than 5 mm, but the number of the conductive wires 20 increases more than necessary, resulting in an increase in cost. Moreover, when the interval dimension (W1) is set longer than 50 mm, the conductive wire 20 in the cloth material 10 becomes sparse (sparse), and the sensor function and the heater function are likely to deteriorate.

例えば布材１０としての織物を作製する場合、緯糸と経糸の一部に導電線材２０を用いるとともに、一部以外の他部に他の線材（絶縁繊維）を用いる。
また布材１０としての編物を作製する場合、ウェール方向の糸又はコース方向の糸の一部に導電線材２０を用いるとともに、一部以外の他部に他の線材（絶縁繊維）を用いる。
そして布材１０としての不織布を作製する場合、例えば導電線材２０と他の線材（典型的にいずれも短繊維）を混合してウェブを形成したのち交絡して不織布とする。 For example, when producing a woven fabric as the fabric material 10, the conductive wire 20 is used for a part of the weft and the warp, and another wire (insulating fiber) is used for the other part than the part.
Moreover, when producing the knitted fabric as the fabric material 10, the conductive wire 20 is used for part of the yarn in the wale direction or the yarn in the course direction, and another wire (insulating fiber) is used for the other part than the part.
And when producing the nonwoven fabric as the cloth material 10, for example, the conductive wire 20 and another wire (typically all short fibers) are mixed to form a web, and then entangled to obtain a nonwoven fabric.

ここで布材１０を表皮材４Ｓに用いる場合、シートの着座性を考慮して、布材１０の裏面にバッキングを施したのち（樹脂層を形成したのち）、パッド材１２や裏基布（図示省略）を配設することができる（図４を参照）。パッド材１２は、柔軟性を備える多孔性の部材であり、例えばウレタンパッドや軟質ウレタンフォームを用いることができる。また裏基布は、例えば織編物や不織布（他の線材）にて構成できる。
そして布材１０とパッド材１２等をこの順で積層して接合手段により一体化したのち、所定の形状にカットする。接合手段として、ラミネート加工（溶着）、縫着、接着などの手法を例示できる。 Here, when the cloth material 10 is used for the skin material 4S, in consideration of the seating property of the sheet, after backing the cloth material 10 (after forming the resin layer), the pad material 12 and the back base cloth ( (Not shown) can be provided (see FIG. 4). The pad material 12 is a porous member having flexibility, and for example, a urethane pad or a flexible urethane foam can be used. The back base fabric can be composed of, for example, a woven or knitted fabric or a non-woven fabric (other wire).
Then, after the cloth material 10 and the pad material 12 are laminated in this order and integrated by the joining means, they are cut into a predetermined shape. Examples of the joining means include techniques such as laminating (welding), sewing, and adhesion.

［第１工程］
第１工程では、分割手段（後述）によって他の線材を布材１０から除去して、布材１０の側部に切れ目を形成する（図２を参照）。このとき他の線材は、分割手段によって切断されるが、導電線材２０は切断されることなくそのままの状態で残存する。
なおパッド材１２（樹脂層又は裏基布）を布材１０に設けた場合には、このパッド材１２等も同時に切断することが好ましい（図４を参照）。 [First step]
In the first step, another wire is removed from the cloth material 10 by a dividing means (described later), and a cut is formed in the side portion of the cloth material 10 (see FIG. 2). At this time, the other wire is cut by the dividing means, but the conductive wire 20 remains as it is without being cut.
In addition, when the pad material 12 (resin layer or back base fabric) is provided in the cloth material 10, it is preferable to cut | disconnect this pad material 12 grade | etc., Simultaneously (refer FIG. 4).

そして布材本体１０ｂから布材片１０ｆを剥き取るように引離して、布材本体１０ｂと布材片１０ｆに分割する。そして分断部２２ａから複数の導電線材２０を露出させる。
このとき各導電線材２０の一端は布材本体１０ｂに固定されており、各導電線材２０の他端は布材片１０ｆに固定されている。すなわち布材片１０ｆが、露出した導電線材２０（被接続部分）を固定するための冶具となる。このため複数の導電線材２０の相対配置位置（並列状）が、布材本体１０ｂと布材片１０ｆによって維持されることとなる。 And it separates so that the cloth material piece 10f may be peeled off from the cloth material main body 10b, and it divides | segments into the cloth material main body 10b and the cloth material piece 10f. And the some conductive wire 20 is exposed from the parting part 22a.
At this time, one end of each conductive wire 20 is fixed to the cloth body 10b, and the other end of each conductive wire 20 is fixed to the cloth piece 10f. That is, the cloth piece 10f serves as a jig for fixing the exposed conductive wire 20 (connected portion). For this reason, the relative arrangement position (parallel shape) of the plurality of conductive wire members 20 is maintained by the cloth material body 10b and the cloth material piece 10f.

（分割手段）
ここで分割手段とは、導電線材２０を残しつつ、極力他の線材だけを除去する手段である。この分割手段は、導電線材２０と他の線材の特性差を考慮して適宜選択される。
例えば両線材の強度差を考慮して、分割手段として、布材１０を物理的に分割する装置（カッターやハサミ等）を使用できる。また両線材の融点や燃焼度合いを考慮して、分割手段としてレーザなどの光学装置を使用できる。また両線材の耐薬品性を考慮して、分割手段として各種の薬剤を使用できる。
なおこれら分割手段を適宜組み合わせて使用することもできる。 (Division means)
Here, the dividing means is means for removing only other wire as much as possible while leaving the conductive wire 20. This dividing means is appropriately selected in consideration of the characteristic difference between the conductive wire 20 and another wire.
For example, in consideration of the difference in strength between the two wires, an apparatus (such as a cutter or scissors) that physically divides the cloth material 10 can be used as the dividing means. In consideration of the melting point and the degree of combustion of both wires, an optical device such as a laser can be used as the dividing means. In consideration of the chemical resistance of both wires, various chemicals can be used as the dividing means.
These dividing means can be used in appropriate combination.

［第２工程］
第２工程では、布材本体１０ｂと布材片１０ｆによって、複数の導電線材２０の相対位置関係を維持しつつ、分断部２２ａから露出した複数の導電線材２０に接続部材３０を電気的につなげる（図３を参照）。
本実施形態の接続部材３０は、導電線材２０の配置方向と直交する向きに長尺な部材であり、複数の導電線材２０に跨ることのできる長さ寸法を有することが好ましい。 [Second step]
In the second step, the connection member 30 is electrically connected to the plurality of conductive wire members 20 exposed from the dividing portion 22a while maintaining the relative positional relationship of the plurality of conductive wire members 20 by the cloth material body 10b and the cloth material piece 10f. (See FIG. 3).
The connection member 30 of the present embodiment is a member that is long in a direction orthogonal to the arrangement direction of the conductive wire 20, and preferably has a length dimension that can extend over the plurality of conductive wires 20.

（接続部材）
接続部材３０として、例えば導線（電線）や導電糸などの接続部材３０（線状）や、導電テープやメッキ体などの接続部材３０（帯状）を用いることができる。メッキ体とは、布帛やゴム製の基材（帯状）にメッキ処理を施した部材であり、湾曲又は屈曲可能な柔軟性を有することが好ましい。
なお接続部材３０と導電線材２０の取付け手法は特に限定しないが、接着、溶着及びカシメ等の手法を例示することができる。 (Connecting member)
As the connection member 30, for example, a connection member 30 (wire shape) such as a conductive wire (electric wire) or conductive yarn, or a connection member 30 (band shape) such as a conductive tape or a plated body can be used. The plated body is a member obtained by plating a fabric or rubber base material (band shape), and preferably has a flexibility that can be bent or bent.
In addition, although the attachment method of the connection member 30 and the conductive wire 20 is not specifically limited, methods, such as adhesion | attachment, welding, and crimping, can be illustrated.

そして図３を参照して、分断部２２ａの導電線材２０上に接続部材３０（帯状）を配置したのち、導電線材２０と接続部材３０を縫着する。そして導電線材２０を接続部材３０で包み込みつつ、布材本体１０ｂに対して布材片１０ｆを下方向（一方向）に内折りする。つぎに布材本体１０ｂの表裏面に接続部材３０を縫着することで、導電線材２０と接続部材３０を電気的につなげる。
このとき本実施形態では、上述の接続作業後において、布材本体１０ｂから布材片１０ｆを剥き取るなどして、導電線材２０の端部２０ｅを露出させることができる。この端部２０ｅ（本数など）を確認することにより、全ての導電線材２０が接続部材３０と電気的につながっているかどうかを確認することができる。 Then, referring to FIG. 3, after connecting member 30 (strip shape) is arranged on conductive wire 20 of dividing portion 22 a, conductive wire 20 and connecting member 30 are sewn. Then, while wrapping the conductive wire 20 with the connecting member 30, the cloth piece 10f is folded inward (one direction) with respect to the cloth body 10b. Next, the conductive wire 20 and the connection member 30 are electrically connected by sewing the connection member 30 to the front and back surfaces of the fabric body 10b.
At this time, in the present embodiment, after the connecting operation described above, the end portion 20e of the conductive wire 20 can be exposed by peeling off the cloth piece 10f from the cloth body 10b. By confirming this end 20e (the number or the like), it is possible to confirm whether or not all the conductive wire members 20 are electrically connected to the connection member 30.

そして接続部材３０に電源ケーブルの端子（図示省略）をつなげて、複数の導電線材２０の電気回路を布材１０（表皮材４Ｓ）に形成する。最後に所定形状の布材１０と、他の布材１１を縫合して表皮材４Ｓを形成する（図４を参照）。

Finally, the cloth material 10 having a predetermined shape and another cloth material 11 are stitched together to form the skin material 4S (see FIG. 4).
After covering the cushioning material 4P with the skin material 4S, the skin material 4S can be used as an electrode or a heater of the capacitive sensor by energizing the plurality of conductive wires 20.

以上説明したとおり、本実施形態では、上述の布材片１０ｆを、露出した導電線材２０（被接続部分）を固定するための冶具として使用する構成（比較的シンプルな構成）である。この構成によって、複数の導電線材２０の相対位置関係を維持することにより、複数の導電線材２０を極力混線させることなく接続部材３０と電気的につなげることができる。このため本実施形態によれば、より簡単な接続作業によって、接続部材３０と導電線材２０を接続性良く電気的につなげることができる。
また本実施形態では、接続後の端部２０ｅを確認することにより、全ての導電線材２０が接続部材３０とつながっているかどうかを容易に確認することができる。 As described above, in the present embodiment, the above-described cloth piece 10f is a configuration (relatively simple configuration) that is used as a jig for fixing the exposed conductive wire 20 (connected portion). With this configuration, by maintaining the relative positional relationship between the plurality of conductive wire rods 20, the plurality of conductive wire rods 20 can be electrically connected to the connection member 30 without being mixed as much as possible. For this reason, according to this embodiment, the connection member 30 and the conductive wire 20 can be electrically connected with good connectivity by a simpler connection operation.
Moreover, in this embodiment, it can be confirmed easily whether all the conductive wire 20 is connected with the connection member 30 by confirming the edge part 20e after a connection.

A connecting member 30 is disposed at the end of the cloth material 10 and protrudes from the back surface of the skin material 4S.

次に図６を参照して、表皮材４Ｓとしての布材１０でクッション材４Ｐを被覆する。そしてクッション材４Ｐの凹部に布材端部（接続部材３０）を配置するのであるが、この構成では、乗員の着座動作などによって接続部材３０とクッション材４Ｐが接触（摩擦）することが懸念される。
そこで本実施形態では、接続部材３０を布材片１０ｆで保護することにより、上記構成において接続部材３０の摩耗や破損を防止又は低減することができる。
また表皮材４Ｓ（布材１０）の搬送時においても、接続部材３０が他部材に接触することがある。このときにも布材片１０ｆの保護により、接続部材３０の摩耗や破損を防止又は低減することができる。
本実施形態によれば、上述の通り、運搬時や使用時における接続部材３０の破損等を防止又は低減して、表皮材４Ｓ（布材１０）の耐久性を向上させることができる。 Next, referring to FIG. 6, cushion material 4P is covered with cloth material 10 as skin material 4S. The cloth material end (connecting member 30) is disposed in the concave portion of the cushion material 4P. With this configuration, there is a concern that the connecting member 30 and the cushion material 4P may come into contact (friction) due to the seating operation of the occupant. The
Therefore, in the present embodiment, by protecting the connecting member 30 with the cloth piece 10f, it is possible to prevent or reduce wear or damage of the connecting member 30 in the above configuration.
In addition, the connection member 30 may come into contact with other members even during the transport of the skin material 4S (cloth material 10). Also at this time, the wear and breakage of the connecting member 30 can be prevented or reduced by protecting the cloth piece 10f.
