Abstract

PURPOSE:To enable a heater wire to be sewed in a support of a single cloth and not make stiff touch when a man is sit on a heater unit by raising in the reverse side of a heater wire supporting plane of a supporter in which the heater wire is sewed. CONSTITUTION:A heater wire 1 is sewed in a supporter 2 of a woven or a knit cloth by an upper thread 3 and a lower thread 4 and raising 6 is formed on the supporter 2 in the reverse side of the heater wire 1 sewed plane. Balance between the thickness of the thread and, in the case of a woven cloth for the supporter 2, the thread density or, in the case of a knit cloth for the supporter 2, knitting density respectively affects softness of the heat unit. Like this, a heater wire can be sewed even if the supporter 2 is a single cloth and a soft heater unit 5 which does not give stiff touch when a person sit on is provided.

拡大図、第１４図、第１５図は第１１図Ａ部の側面図を
示す。FIG. 11 shows a heater wire 33 attached to a support 32 that can be sewn, such as cloth.
An example is shown in which the upper thread 34 and lower thread 35 are used. 12th
The figure shows an enlarged view of section A in FIG. 11, FIG. 13 shows an enlarged view of section B in FIG. 11, and FIGS. 14 and 15 show side views of section A in FIG. 11.

第１１図〜第１５図において、支持体３２は不織布や布
切（＆！布、織布等）にウレタンフオームを貼合せたも
の等が一般に用いられている。In FIGS. 11 to 15, the support 32 is generally a nonwoven fabric or a fabric (&! fabric, woven fabric, etc.) bonded with urethane foam.

第１４図は支持体３２に不織布や、布切（編布、織布等
）を単独で用いた例を示す。FIG. 14 shows an example in which a nonwoven fabric or a cut cloth (knitted fabric, woven fabric, etc.) is used alone as the support 32.

また、第１５図は支持体３２として２枚の布切３６（４

を示す。In addition, in FIG. 15, two pieces of cloth 36 (4
An example is shown in which a urethane foam 37 is laminated between the fabric, woven fabric, etc.

発明が解決しようとする！ｉ題 しかしながらこのような従来のヒータユニット２５では
、次のようなｉｏがあった。Invention tries to solve! However, in such a conventional heater unit 25, there was the following io.

（１）　　第１１図に示す方法では、支持体３２が柔ら
かい場合、支持体３２がヒータ＊３３の弾性に負けて縫
合が不可能であった。(1) In the method shown in FIG. 11, when the support body 32 is soft, the support body 32 is overcome by the elasticity of the heater*33, making suturing impossible.

特に第１３図に示すようなコーナ部ではヒータ線３３の
弾性により支持体３２にしわが発生した。Particularly at the corners as shown in FIG. 13, wrinkles were generated in the support 32 due to the elasticity of the heater wire 33.

そこで、支持体３２はヒータ線３３の弾性に負けない剛
軟性を必要とし、支持体３２に樹脂加工等を施して硬さ
を与えていた。Therefore, the support body 32 is required to have flexibility comparable to the elasticity of the heater wire 33, and the support body 32 is given hardness by applying resin processing or the like.

そのため、第９図に示すように座席２０にヒータユニッ
ト２５を装着した場合、ゴワゴワ感が生し座り心地を損
なう欠点があった。Therefore, when the heater unit 25 is attached to the seat 20 as shown in FIG. 9, there is a drawback that the seat 20 feels stiff and the seating comfort is impaired.

（２）そこで、このような欠点を補う為第１５図に示す
ように支持体３２にウレタンフオーム３７を貼合せて柔
軟性を持たせる必要があった。(2) Therefore, in order to compensate for such drawbacks, it was necessary to attach a urethane foam 37 to the support 32 to give it flexibility, as shown in FIG.

この場合、ウレタンフオーム３７のみでは耐久性が無く
、又、滑りが悪く縫合が出来ないことからウレタンフオ
ーム３７に害物３６を貼合せて用いられていた。In this case, the urethane foam 37 alone lacks durability and is too slippery to be sewn, so the urethane foam 37 has been laminated with the harmful material 36.

そのため、コストアップだけでなく支持体３２の厚みが
増してロール状での供給長に限度があり作業性を著しく
悪くしていた。This not only increases costs but also increases the thickness of the support 32, which limits the supply length in roll form and significantly impairs workability.

本発明は上記課題を解決し、布切−枚の支持体でもヒー
タ線を縫合し、かつ着座時にゴワゴワ感を与えない柔軟
性をもったヒータユニットを提供するものである。The present invention solves the above-mentioned problems and provides a flexible heater unit in which heater wires can be sewn even to a support made of cut cloth, and which does not give a stiff feeling when seated.

ｉｎを解決するための手段 上記の課題を解決するた、本発明のヒータユニットは、
支持体に害物（ｍ布や織布）を用いヒータ線を縫合する
面と逆の面に起毛を施したものである。Means for Solving In In order to solve the above problems, the heater unit of the present invention has the following features:
The support is made of a harmful material (m-cloth or woven fabric), and the side opposite to the side to which the heater wire is sewn is brushed.

作用 上記構成により、支持体が害物のみであってもヒータ線
の縫合が可能で、柔軟性も確保出来る。Effect With the above configuration, even if the support is only a harmful object, the heater wire can be sutured and flexibility can be ensured.

実施例 以下、本発明の実施例を添付図面にもとすいて説明する
。Embodiments Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

第１図において、５は本発明のヒータユニットで、ヒー
タ線１は（織布や織布）を用いた支持体２に上糸３と下
糸４（第２図に示す）により縫合されている。In FIG. 1, 5 is a heater unit of the present invention, and a heater wire 1 is sewn to a support 2 made of (woven fabric or woven fabric) with an upper thread 3 and a lower thread 4 (shown in FIG. 2). There is.

第２図は支持体２に縫合したヒータ線１の状態の一例を
示す拡大側面図である。FIG. 2 is an enlarged side view showing an example of the state of the heater wire 1 sewn to the support body 2.

第２図は支持体２に、ヒータ線１が縫合される面と逆の
面に起毛６を施した例を示す。FIG. 2 shows an example in which a raised surface 6 is applied to the support 2 on the opposite surface to the surface to which the heater wire 1 is sewn.

ここで支持体２は織布の場合は糸密度、織布の場合は纏
み地密度と使用する糸の太さのバランスがその柔軟性に
大きく影響する。Here, the flexibility of the support 2 is greatly influenced by the thread density in the case of a woven fabric, and the balance between the wrapping density and the thickness of the thread used in the case of a woven fabric.

実験では織布の場合、糸の太さが２０〜３０番手（メー
トル式）、糸密度が３０〜４０本／インチにすることで
ヒータ線の縫合も可能で起毛後の柔軟性も得る事が出来
た。In experiments, in the case of woven fabric, by setting the thread thickness to 20 to 30 (metric type) and the thread density to 30 to 40 threads/inch, it was possible to sew heater wires and obtain flexibility after raising. done.

この時、起毛は柔軟性を確保するには略２〜５閣（シャ
ーリング後）の起毛であれば問題はない。At this time, in order to ensure flexibility, there is no problem if the napping is approximately 2 to 5 times (after shirring).

又、編布の場合は糸の太さが略１００デニール、密度が
略５００　ｇ　／　ｒｒｒであればヒータ線の縫合に問
題はない。Further, in the case of knitted fabric, if the thread thickness is approximately 100 denier and the density is approximately 500 g/rrr, there will be no problem in sewing the heater wire.

ただし、第７図の拡大組織図（平織の略図）に示す。However, it is shown in the enlarged organization chart (schematic diagram of plain weave) in Fig. 7.

織布９の場合は横糸１１と縦糸１０が交錯する組織の為
、ヒータ線を縫合後外形をカットした時、端面にほつれ
や糸抜け（スリップ現象）が生じやすい欠点がある。In the case of the woven fabric 9, since the weft threads 11 and the warp threads 10 intersect with each other, when the outer shape is cut after sewing the heater wires, fraying and thread slipping (slip phenomenon) tend to occur at the end surfaces.

そこでこのような場合、第３図および、第４図の拡大斜
視図に示すようにカットされた支持体２の周縁を端面か
ら３〜６ｍ（１＋）の位置で縫合７する事で上記はつれ
を防止する事が出来る。Therefore, in such a case, as shown in the enlarged perspective views of FIG. 3 and FIG. can be prevented.

又、他の手段として第５図および、第６図の拡大斜視図
に示すようにカットさた支持体２の周縁を端面から３〜
６ｍ（ｌｄの位置に樹脂８を塗布する事で上記はつれを
防止する事が出来る。Alternatively, as shown in the enlarged perspective views of FIG. 5 and FIG.
The above peeling can be prevented by applying resin 8 to the position of 6m (ld).

この場合、樹脂８は帯状や点状でも良く、又複数本の樹
脂を塗布（第５図、第６図は二本の例を示す）する事で
より効果を得る事が出来る。In this case, the resin 8 may be in the form of a band or dots, and more effects can be obtained by applying a plurality of resins (FIGS. 5 and 6 show two examples).

更に、ヒータユニット５の全体に任意の間隔で複数本の
樹脂を塗布する事でより一段と大きな効果がある。Furthermore, an even greater effect can be obtained by applying a plurality of resins to the entire heater unit 5 at arbitrary intervals.

第８図に示すような織布１２の場合は上記のようなほつ
れや糸抜け（スリップ現象）が生じる恐れがなく縫合や
樹脂の塗布は必要ない。In the case of the woven fabric 12 as shown in FIG. 8, there is no risk of fraying or thread coming out (slip phenomenon) as described above, and there is no need for stitching or resin application.

発明の効果 以上の実施例の説明から明らかなように、本発明のヒー
タユニットは、支持体に起毛を施す事により、次のよう
な効果を得る事ができる。Effects of the Invention As is clear from the description of the embodiments above, the heater unit of the present invention can obtain the following effects by applying fluff to the support.

（１）　　ヒータ線の弾性に負けないで縫合が可能であ
り、着座時ゴワゴワ感を解消する柔軟性をもったヒータ
ユニットが製造出来る。(1) It is possible to manufacture a flexible heater unit that can be sewn without losing the elasticity of the heater wire and eliminates the stiff feeling when sitting.

（２）　　ウレタンフオーム等柔軟性を得る為の別材料
を使用する必要がなく、布切（織布、編布）単体で支持
体が構成出来、コストダウンと同時に大幅に作業性が向
上する。(2) There is no need to use a separate material such as urethane foam to obtain flexibility, and the support can be constructed from a single piece of cloth (woven or knitted fabric), reducing costs and greatly improving workability.
