Can efficiently discharge static electricity to the outside and prevent the occurrence of static electricity failure.
　また、特許文献２には、「繊維フィラメントからなるワディング材の表面に表皮材を接着一体化した自動車内装用表面材において、前記ワディング材に自己放電により静電気中和機能を発揮する除電繊維を混入させた自動車内装用表面材」が開示されている。 Patent Document 2 states that “in a car interior surface material in which a skin material is bonded and integrated to the surface of a wadding material made of fiber filaments, the wading material is mixed with a neutralizing fiber that exhibits a static neutralization function by self-discharge. "Surface material for automobile interior".
　特許文献２の自動車内装用表面材によれば、導電糸および導電性物質を用いることなくワディング材に除電繊維を混入するのみで十分な帯電防止機能を発揮することができ、また表皮材の色や柄の選択自由度を拡げることができるとともにワディング材が硬くなることがなく優れたクッション性を確保することができ、更にはアースを必要とせず簡単な構造であり、また表面材としての構造も極めて簡単で生産コストも大幅に低減することができる。 According to the automotive interior surface material of Patent Document 2, it is possible to exhibit a sufficient antistatic function only by mixing the neutralizing fiber into the wadding material without using conductive yarns and conductive materials, and the color of the skin material. In addition to expanding the degree of freedom of selection of patterns and patterns, it is possible to ensure excellent cushioning without stiffening the wadding material, and further, a simple structure that does not require grounding, and a structure as a surface material It is extremely simple and the production cost can be greatly reduced.
　一方、自動車用シートの抗菌性、消臭効果に関する背景技術としては、例えば、特許文献３のような技術がある。特許文献３には、「光触媒粒子表面をフッ素系多孔質層で被覆した抗菌性防臭粒子を繊維表面に付着させた抗菌性防臭繊維」が開示されている。 On the other hand, as a background art regarding the antibacterial property and deodorizing effect of the automobile seat, for example, there is a technique such as Patent Document 3. Patent Document 3 discloses “an antibacterial deodorant fiber in which antibacterial deodorant particles whose photocatalyst particle surfaces are coated with a fluorine-based porous layer are attached to the fiber surface”.
　特許文献３の抗菌性防臭繊維によれば、水（若しくは水蒸気）の存在下、不存在下に拘わらず、銅及びアルミニウムの組み合わせによる抗菌性能を遥かに凌ぐ優れた抗菌性防臭性能が、常に発揮される。 According to the antibacterial deodorant fiber of Patent Document 3, an excellent antibacterial deodorant performance that far surpasses the antibacterial performance of the combination of copper and aluminum is always exhibited regardless of the presence or absence of water (or water vapor). Is done.

　上記のように、自動車用シートなどの車両用シートにおいては、振動吸収性やクッション性などの座り心地に加え、静電気対策や抗菌性、消臭効果といった乗員の快適性を向上するシートづくりが重要な課題となっている。 As mentioned above, it is important to make seats that improve passenger comfort, such as anti-static, antibacterial, and deodorizing effects, in addition to seating comfort such as vibration absorption and cushioning, for vehicle seats such as automobile seats. It is a difficult issue.
　従来の自動車用シートにおいては、シートのクッション材として一般的に使用されているウレタンパッドは、主原料であるイソシアネート溶液およびポリオール溶液等を混合させながら型に流し込み、混合溶液の化学反応により発泡させることにより形成される。この発泡したウレタンフォームは導電性が低く（電気抵抗値：１０６Ω・ｍ以上）、摩擦により容易に静電気が溜まる、いわゆる帯電体である。 In a conventional automobile seat, a urethane pad generally used as a cushion for a seat is poured into a mold while mixing an isocyanate solution and a polyol solution, which are main raw materials, and foamed by a chemical reaction of the mixed solution. Is formed. This foamed urethane foam has a low electrical conductivity (electric resistance value: 10 6 Ω · m or more) and is a so-called charged body in which static electricity easily accumulates due to friction.
　そのため、シートクッションやシートバックと乗員の被服との間の摩擦により静電気が発生し、ウレタンパッドに静電気が蓄積され、乗員及び乗員の被服にも同様に静電気が溜まる。帯電状態のまま車を降りようとする際に、ドアの金属部分や物に触った瞬間に乗員の体に溜まった静電気が放電され不快に感じてしまう。 Therefore, static electricity is generated by friction between the seat cushion or the seat back and the occupant's clothing, static electricity is accumulated on the urethane pad, and static electricity is similarly accumulated on the occupant and the occupant's clothing. When trying to get out of the car in a charged state, the static electricity accumulated on the passenger's body is discharged at the moment of touching the metal part or object of the door, which makes it uncomfortable.
　また、ウレタンは通気性が悪く蒸れ易いため、シートの表面に菌が繁殖し不衛生な状態となり易く、臭いも付き易い。 In addition, since urethane is poorly breathable and easily stuffy, bacteria are likely to grow on the surface of the sheet, making it unsanitary and easily odorizing.
　特許文献１の静電気誘導放出装置では、シートの表面又は内部に導電体で形成された鎖或は導線又は網若しくは薄板、盤体等の静電気誘導体を設けているため、シートへの静電気の蓄積は緩和されるものの、シートのクッション性が損なわれてしまう。 In the electrostatic induction emission device of Patent Document 1, since a sheet or chain formed of a conductor or a conductive wire, or a net or thin plate, a board or other electrostatic derivative is provided on the surface or inside of the sheet, accumulation of static electricity on the sheet is not Although it is alleviated, the cushioning property of the seat is impaired.
　また、特許文献２の自動車内装用表面材は、ワディング材に除電繊維を混入することで帯電防止を行うため、シートのクッション性は確保されるが、アースに接続せずにワディングに混入した除電繊維のみで除電を行うため、ワディング材に混入した除電繊維の除電能力を超えた静電気に対する除電は不十分である。 In addition, since the surface material for automobile interior of Patent Document 2 prevents the electrification by mixing the neutralizing fiber into the wading material, the cushioning property of the seat is ensured, but the neutralization mixed into the wadding without being connected to the ground. Since the neutralization is performed only with the fibers, the neutralization with respect to static electricity exceeding the neutralization capability of the neutralization fibers mixed in the wadding material is insufficient.
　また、特許文献３の抗菌性防臭繊維では、抗菌性、消臭効果は得られるものの、放電シートによる静電気対策は限界があり、乗員の快適性を向上するには不十分である。 In addition, although the antibacterial deodorant fiber of Patent Document 3 can provide antibacterial and deodorizing effects, there are limits to countermeasures against static electricity using a discharge sheet, which are insufficient for improving passenger comfort.
　そこで、本発明の目的は、車両用シートにおいて、通気性及びクッション性を維持しつつ、静電気の発生を抑え、抗菌性・消臭効果に優れた車両用シートを提供することにある。 Therefore, an object of the present invention is to provide a vehicle seat that is excellent in antibacterial and deodorizing effects while suppressing the generation of static electricity while maintaining breathability and cushioning properties.

　以下、図面を用いて本発明の実施例を説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
　先ず、図１５を用いて、自動車等に用いられる一般的な車両用シートについて説明する。図１５は一般的な車両用シートの全体概要を示している。車両用シート１は、その主な部位として、シートの座面部分となるシートクッション２、シートの背もたれ部分となるシートバック３、乗員の頭部および頸部を保護するヘッドレスト４を有している。シートクッション２の両脇には、座面部のサイド部分のサポートとなるサイドサポート５が設けられている。 First, a general vehicle seat used for an automobile or the like will be described with reference to FIG. FIG. 15 shows the general outline of a general vehicle seat. The vehicle seat 1 includes, as main parts thereof, a seat cushion 2 that serves as a seat surface portion of the seat, a seat back 3 that serves as a seat back portion, and a headrest 4 that protects the head and neck of the occupant. . On both sides of the seat cushion 2, side supports 5 are provided to support the side portions of the seat surface portion.
　図１５に図示していないが、シートクッション２およびシートバック３の内部（下部）にはシートの骨格となるシートフレームを有しており、シートフレームは車体に固定されている。つまり、車両用シート１は、シートの骨格となるシートフレーム上に座面部分となるシートクッション２が設けられ、シートクッション２の背側にはリクライニングアジャスタを介して背もたれ部分となるシートバック３が据え付けられ、さらにそのシートバック３の上部には乗員の頭部および頸部を保護するヘッドレスト４が取り付けられる構造となっている。 Although not shown in FIG. 15, the seat cushion 2 and the seat back 3 have a seat frame serving as a skeleton of the seat, and the seat frame is fixed to the vehicle body. That is, the vehicle seat 1 is provided with a seat cushion 2 serving as a seat surface portion on a seat frame serving as a skeleton of the seat, and a seat back 3 serving as a backrest portion via a reclining adjuster on the back side of the seat cushion 2. In addition, a headrest 4 for protecting the head and neck of the occupant is attached to the upper portion of the seat back 3.
　図１３および図１４を用いて、本発明の課題をより詳しく説明する。図１３は従来の車両用シートの全体概要を示し、図１４は従来の車両用シートのシートクッション２の断面を示している。 The problem of the present invention will be described in more detail with reference to FIGS. FIG. 13 shows an overall outline of a conventional vehicle seat, and FIG. 14 shows a cross section of the seat cushion 2 of the conventional vehicle seat.
　図１３に示すように、車両用シートはその主要な構成部品として、シートの座面部分となるシートクッション２およびシートの背もたれ部分となるシートバック３から構成されている。図１３は、表皮およびワディングからなるトリムカバー（シートカバー）を取り除いた状態を示しており、その素材はウレタン発泡体である。 As shown in FIG. 13, the vehicle seat is composed of a seat cushion 2 serving as a seat surface portion of a seat and a seat back 3 serving as a seat back portion of the seat as main components. FIG. 13 shows a state in which a trim cover (seat cover) composed of a skin and a wadding is removed, and the material thereof is urethane foam.
　このウレタン発泡体は、上記のように、主原料であるイソシアネート溶液およびポリオール溶液等を混合させながら型に流し込み、混合溶液の化学反応により発泡させることにより形成される。この発泡したウレタンフォームは導電性が低く（電気抵抗値：１０６Ω・ｍ以上）、摩擦により容易に静電気が溜まり易い、いわゆる帯電体である。 As described above, this urethane foam is formed by pouring into a mold while mixing an isocyanate solution and a polyol solution, which are main raw materials, and foaming by a chemical reaction of the mixed solution. This foamed urethane foam is a so-called charged body that has low conductivity (electric resistance value: 10 6 Ω · m or more) and easily accumulates static electricity due to friction.
　従来の車両用シートのシートクッションは、図１４に示すように、シートフレーム９上にクッション材の基盤となるウレタンパッド８設けられ、さらに表皮材６およびワディング７からなるトリムカバーにより覆われている。ワディング７は、ウレタンパッド８と同様にウレタンを素材として形成されており、シートの中綿としての機能も果たしている。ウレタンパッド８およびトリムカバーとして使われるワディング７は、上述の通り、ウレタンフォームを素材として形成されているため、帯電体となり静電気などの電荷が容易に蓄積してしまう。 As shown in FIG. 14, a conventional seat cushion for a vehicle seat is provided with a urethane pad 8 which is a base of a cushion material on a seat frame 9 and is further covered with a trim cover made of a skin material 6 and a wadding 7. . The wadding 7 is made of urethane as a material like the urethane pad 8 and also functions as a batting of the sheet. Since the urethane pad 8 and the wadding 7 used as the trim cover are formed of urethane foam as described above, they become a charged body and easily accumulate charges such as static electricity.
　また、トリムカバーの一部である表皮材６は、一般的に合成皮革やポリエチレンテレフタレート（ＰＥＴ）等の合成繊維などを素材として形成さており、やはり導電性が低く、帯電体であり、ワディング７やウレタンパッド８と同様に、静電気が蓄積し易い。このように、従来の車両用シートでは、表皮材６、ワディング７、ウレタンパッド８のいずれも帯電体であり、それぞれの表面および内部に静電気が蓄積し易い。そのため、乗員の被服１０とシートクッションとの間に摩擦が生じた際に、乗員の被服１０すなわち乗員自体も帯電してしまい、例えば、降車する際にドアに触れた瞬間に放電し、電気ショックにより不快に感じる。 Further, the skin material 6 which is a part of the trim cover is generally made of synthetic leather or synthetic fiber such as polyethylene terephthalate (PET), etc., and has low conductivity and is a charged body. Like the urethane pad 8, static electricity tends to accumulate. Thus, in the conventional vehicle seat, all of the skin material 6, the wadding 7 and the urethane pad 8 are charged bodies, and static electricity tends to accumulate on the respective surfaces and inside. Therefore, when friction is generated between the occupant's clothing 10 and the seat cushion, the occupant's clothing 10, that is, the occupant itself is also charged, and for example, the electric shock is discharged at the moment of touching the door when getting off the vehicle. Feels uncomfortable.
　また、ワディング７、ウレタンパッド８の素材であるウレタンは通気性が悪く蒸れ易いため、菌が繁殖し易く、不衛生で臭いも付き易い。 In addition, urethane, which is the material of the wadding 7 and the urethane pad 8, has poor air permeability and is easily stuffy, so that bacteria are easy to propagate, and it is unsanitary and easily smells.
　次に、図１乃至図４を用いて本発明の実施例１における車両用シートについて説明する。図１は、実施例１における車両用シートの全体概要を示している。本実施例における車両用シートの主要な構成は、図１３に示す従来の車両用シートと同様に、シートクッション２およびシートバック３から構成されている。 Next, the vehicle seat according to the first embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows an overall outline of a vehicle seat in the first embodiment. The main structure of the vehicle seat in the present embodiment is composed of a seat cushion 2 and a seat back 3 as in the conventional vehicle seat shown in FIG.
　図２に、本実施例における車両用シートのシートクッション２およびシートバック３の一部断面を示す。シートフレーム９上にウレタンパッド８が設けられ、さらにその上を表皮材６およびワディングからなるトリムカバーにより覆われた形で形成されている。その点においては、図１４に示す従来の車両用シートの断面と同じ構成となっている。しかし、本実施例における車両用シートは、図２に示すように、ワディング１１に銀（Ａｇ）を添加した繊維体を用いている点において、従来の車両用シートとは異なる。つまり、本実施例の車両用シートでは、トリムカバーのワディングに銀（Ａｇ）添加ワディング１１を用いている。 FIG. 2 shows a partial cross section of the seat cushion 2 and the seat back 3 of the vehicle seat in the present embodiment. A urethane pad 8 is provided on the seat frame 9 and is further covered with a trim cover made of a skin material 6 and a wadding. In that respect, it has the same configuration as the cross section of the conventional vehicle seat shown in FIG. However, the vehicle seat in the present embodiment is different from the conventional vehicle seat in that a fiber body in which silver (Ag) is added to the wadding 11 is used as shown in FIG. That is, in the vehicle seat of the present embodiment, the silver (Ag) -added wadding 11 is used for the wadding of the trim cover.
　図３および図４を用いて、本実施例における車両用シートの作用効果について説明する。図３に示すように、シートクッション２と乗員の被服１０との摩擦により発生した静電気は、銀（Ａｇ）添加ワディング１１を介して、銀（Ａｇ）添加ワディング１１と電気的に接続しているシートフレーム９に流れて（逃げて）行く。シートフレーム９は、自動車等の車体１２に固定されており、フレームグラウンドとしてシートクッション２に発生した静電気を受容する機能を果たしている。つまり、銀（Ａｇ）添加ワディング１１はシートフレーム９に接するように取り付けられているため、銀（Ａｇ）添加ワディング１１およびシートフレーム９はアースとして機能している。 3 and 4 will be used to explain the effects of the vehicle seat in this embodiment. As shown in FIG. 3, static electricity generated by friction between the seat cushion 2 and the occupant's clothing 10 is electrically connected to the silver (Ag) -added wadding 11 via the silver (Ag) -added wadding 11. It flows to the seat frame 9 (runs away). The seat frame 9 is fixed to a vehicle body 12 such as an automobile, and fulfills a function of receiving static electricity generated in the seat cushion 2 as a frame ground. That is, since the silver (Ag) -added wadding 11 is attached so as to contact the seat frame 9, the silver (Ag) -added wadding 11 and the seat frame 9 function as a ground.
　ここで、本実施例における表皮材６は、材質にポリエチレンテレフタレート（ＰＥＴ）を用いて形成されており、その厚みは１ｍｍ～１．５ｍｍ程度である。また、銀（Ａｇ）添加ワディング１１は、その材質として、例えば、ポリプロピレン（ＰＰ）およびポリエチレンテレフタレート（ＰＥＴ）を素材とした繊維で形成されており、銀（Ａｇ）の含有量はワディング全体の重量の１％～５％程度が好適である。また、クッション性を確保するため、その厚みは３ｍｍ～１０ｍｍ程度としている。ウレタンパッド８は、ウレタンフォームを素材として形成されており、その厚みはやはりクッション性を確保するため、５５ｍｍ～１００ｍｍ程度としている。 Here, the skin material 6 in the present embodiment is formed using polyethylene terephthalate (PET) as a material, and the thickness thereof is about 1 mm to 1.5 mm. The silver (Ag) -added wadding 11 is made of, for example, fibers made of polypropylene (PP) and polyethylene terephthalate (PET) as materials, and the content of silver (Ag) is the weight of the entire wadding. About 1% to 5% is preferable. Further, in order to ensure cushioning properties, the thickness is about 3 mm to 10 mm. The urethane pad 8 is made of urethane foam, and its thickness is about 55 mm to 100 mm in order to ensure cushioning.
　また、繊維材は芯鞘構造繊維を使用し、繊維に電気伝導性に優れた銀（Ａｇ／電気抵抗値：１０－８Ω・ｍ以下）を添加することで繊維材の導電性を確保している。 The fiber material uses core-sheath structure fibers, and the conductivity of the fiber material is ensured by adding silver (Ag / electric resistance value: 10 −8 Ω · m or less) excellent in electrical conductivity to the fiber. ing.
　本実施例では、シートフレーム９をフレームグランドとして説明したが、シートフレーム９が直接接地していても良く、また、シートフレーム９が固定される車体１２が接地されていても同様の効果を得ることができる。 In the present embodiment, the seat frame 9 is described as the frame ground. However, the seat frame 9 may be directly grounded, and the same effect can be obtained even when the vehicle body 12 to which the seat frame 9 is fixed is grounded. be able to.
　また、図２のように、表皮材６或いはウレタンパッド８もシートフレーム９と接触するように、すなわち表皮材６或いはウレタンパッド８がシートフレーム９と電気的に接続するように設けても良い。 Further, as shown in FIG. 2, the skin material 6 or the urethane pad 8 may be provided so as to come into contact with the seat frame 9, that is, the skin material 6 or the urethane pad 8 may be electrically connected to the seat frame 9.
　本実施例の車両用シートによれば、乗員すなわち乗員の被服１０とシートクッションとの間で発生した静電気を、乗員（乗員の被服）から、トリムカバーすなわち表皮材６および銀（Ａｇ）添加ワディング１１、シートフレーム９を介して車体１２へ逃がすことができる。また、銀（Ａｇ）添加ワディング１１に含まれる銀（Ａｇ）は抗菌性、消臭効果を有しており、シートクッションにおける菌の増殖を抑えることができる。 According to the vehicle seat of the present embodiment, static electricity generated between the occupant, that is, the occupant's clothing 10 and the seat cushion, is transferred from the occupant (occupant's clothing) to the trim cover, that is, the skin material 6 and the silver (Ag) -added padding. 11. It can escape to the vehicle body 12 through the seat frame 9. In addition, silver (Ag) contained in the silver (Ag) -added wadding 11 has antibacterial and deodorizing effects, and can suppress the growth of bacteria in the seat cushion.
　さらに、銀（Ａｇ）添加ワディング１１は、銀（Ａｇ）添加繊維により形成されているため、従来のウレタンを素材とするワディングに比べて、通気性の点においても優れている。従って、通気性及びクッション性を損なうことなく、静電気の発生を抑え、抗菌性・消臭効果に優れた車両用シートを実現することが可能となる。 Furthermore, since the silver (Ag) -added wadding 11 is formed of silver (Ag) -added fibers, it is superior in terms of air permeability as compared with a conventional wadding made of urethane. Therefore, it is possible to realize a vehicle seat that suppresses the generation of static electricity and has an excellent antibacterial and deodorizing effect without impairing air permeability and cushioning properties.
　なお、本実施例においては、銀（Ａｇ）添加ワディング１１をシートクッション２に用いた例を主に説明したが、シートバック３に銀（Ａｇ）添加ワディング１１を用いることにより、シートバック３においても同様に静電気の発生を抑え、抗菌性・消臭効果を得ることができる。 In this embodiment, the example in which the silver (Ag) -added wadding 11 is mainly used for the seat cushion 2 has been described. However, by using the silver (Ag) -added wadding 11 for the seat back 3, the seat back 3 In the same way, the generation of static electricity can be suppressed and antibacterial and deodorizing effects can be obtained.
　図５乃至図７を用いて、本発明の実施例２における車両用シートについて説明する。図５は、その構造が分かり易いように、トリムカバーすなわち表皮材６およびワディング７を取り除いたシートクッション２の斜視図および一部断面を示している。本実施例におけるシートクッション２は、図５に示すように、ウレタンパッド８の一部に、ウレタンパッド８の上面から下面にかけて貫通する開孔が設けられており、その開孔内部に銀（Ａｇ）添加繊維１３が充填されている。つまり、本実施例のウレタンパッド８は、その素材であるウレタンの一部を銀（Ａｇ）添加繊維に置き換えたハイブリッド構造のパッドすなわちハイブリッドパッドとなっている。 The vehicle seat according to the second embodiment of the present invention will be described with reference to FIGS. FIG. 5 shows a perspective view and a partial cross section of the seat cushion 2 with the trim cover, that is, the skin material 6 and the wadding 7 removed, so that the structure can be easily understood. As shown in FIG. 5, the seat cushion 2 in this embodiment is provided with an opening penetrating from the upper surface to the lower surface of the urethane pad 8 in a part of the urethane pad 8, and silver (Ag) inside the opening. ) Additive fiber 13 is filled. That is, the urethane pad 8 of the present embodiment is a hybrid pad, that is, a hybrid pad in which a part of urethane as the material is replaced with silver (Ag) added fibers.
　図６は、図５のハイブリッドパッドを用いたシートクッションの一部断面を示している。ハイブリッドパッドをシートフレーム９上に据え付け、さらにハイブリッドパッド上にシートクッションの中綿となるワディング７および表皮材６を設けている。シートフレーム９は、実施例１と同様に車体１２に接続し、フレームグラウンド或いはアース（接地）として機能する。図６に示すように、ウレタンパッド８の開孔に充填された銀（Ａｇ）添加繊維１３とシートフレーム９は電気的に接続しており、表皮材６やワディング７或いはウレタンパッド８に溜まった静電気は、銀（Ａｇ）添加繊維１３およびシートフレーム９を介してフレームグラウンドへ放電される。 FIG. 6 shows a partial cross section of a seat cushion using the hybrid pad of FIG. The hybrid pad is installed on the seat frame 9, and the wadding 7 and the skin material 6 which are the padding of the seat cushion are provided on the hybrid pad. The seat frame 9 is connected to the vehicle body 12 as in the first embodiment, and functions as a frame ground or an earth (ground). As shown in FIG. 6, the silver (Ag) -added fibers 13 filled in the openings of the urethane pad 8 and the seat frame 9 are electrically connected and accumulated in the skin material 6, the wadding 7, or the urethane pad 8. Static electricity is discharged to the frame ground through the silver (Ag) -added fibers 13 and the seat frame 9.
　図７に、図６のハイブリッドパッドによる静電気の放電経路を示す。乗員の被服１０とシートの表皮材６との摩擦によって表皮材６やワディング７或いはウレタンパッド８に溜まった静電気は、ハイブリッドパッドの銀（Ａｇ）添加繊維１３部分およびシートフレーム９を通り、車体１２へと放出することができる。 FIG. 7 shows a discharge path of static electricity by the hybrid pad of FIG. Static electricity accumulated in the skin material 6, the wadding 7 or the urethane pad 8 due to the friction between the occupant's clothing 10 and the seat skin material 6 passes through the silver (Ag) -added fiber 13 portion of the hybrid pad and the seat frame 9, and the vehicle body 12. Can be released.
　ここで、銀（Ａｇ）添加繊維１３に含まれる銀（Ａｇ）の含有量は、ウレタンパッド８の開孔に充填される繊維全体の重量の１％～５％程度が好適である。 Here, the content of silver (Ag) contained in the silver (Ag) -added fiber 13 is preferably about 1% to 5% of the total weight of the fiber filled in the pores of the urethane pad 8.

Further, it can escape to the vehicle body 12 through the wadding 7, the silver (Ag) -added fiber 13 filled in the opening of the urethane pad 8, and the seat frame 9.
　また、銀（Ａｇ）添加繊維１３に含まれる銀（Ａｇ）は抗菌性、消臭効果を有しており、シートクッションにおける菌の増殖を抑えることができる。さらに、銀（Ａｇ）添加繊維１３は、繊維をベースとして形成されているため、従来のウレタンパッドに比べて、通気性の点においても優れている。従って、通気性及びクッション性を損なうことなく、静電気の発生を抑え、抗菌性・消臭効果に優れた車両用シートを実現することが可能となる。 Further, silver (Ag) contained in the silver (Ag) -added fiber 13 has antibacterial and deodorizing effects, and can suppress the growth of bacteria in the seat cushion. Furthermore, since the silver (Ag) -added fiber 13 is formed based on a fiber, it is superior in terms of air permeability as compared with a conventional urethane pad. Therefore, it is possible to realize a vehicle seat that suppresses the generation of static electricity and has an excellent antibacterial and deodorizing effect without impairing air permeability and cushioning properties.
　なお、本実施例においても、上記で説明したハイブリッドパッドをシートバック３に用いることにより、シートクッション同様にシートバックの静電気の発生を抑え、抗菌性・消臭効果を得ることができる。 In the present embodiment as well, by using the hybrid pad described above for the seat back 3, it is possible to suppress the generation of static electricity in the seat back and obtain an antibacterial and deodorizing effect as in the seat cushion.
　図８を用いて、本発明の実施例３における車両用シートについて説明する。図８は、図５に示すハイブリッドパッドすなわち一部に銀（Ａｇ）添加繊維１３を用いたウレタンパッドに替えて、パッド全てを銀（Ａｇ）添加繊維１３に置き換えた実施例を示している。つまり、図６におけるウレタンパッド８および銀（Ａｇ）添加繊維１３の部分を全て銀（Ａｇ）添加繊維１３で形成している。 The vehicle seat according to the third embodiment of the present invention will be described with reference to FIG. FIG. 8 shows an embodiment in which the entire pad is replaced with silver (Ag) -added fibers 13 instead of the hybrid pad shown in FIG. 5, that is, a urethane pad partially using silver (Ag) -added fibers 13. That is, the urethane pad 8 and the silver (Ag) -added fiber 13 in FIG. 6 are all formed of the silver (Ag) -added fiber 13.
　素材の全てを銀（Ａｇ）添加繊維１３で形成したパッドを、図示しないが、図６のように、シートフレーム９上に据え付け、さらにパッド上に表皮材６およびワディング７からなるトリムカバーを設けるシートクッション構造となっている。 Although not shown, a pad made of silver (Ag) -added fibers 13 is installed on the seat frame 9 and a trim cover made of the skin material 6 and the wadding 7 is provided on the pad as shown in FIG. It has a seat cushion structure.
　ここで、銀（Ａｇ）添加繊維１３に含まれる銀（Ａｇ）の含有量は、繊維全体の重量の１％～５％程度が好適である。 Here, the content of silver (Ag) contained in the silver (Ag) -added fiber 13 is preferably about 1% to 5% of the total weight of the fiber.
　本実施例の車両用シートによれば、実施例１或いは実施例２と同様に、乗員すなわち乗員の被服１０とシートクッションとの間で発生した静電気を、乗員（乗員の被服）から、トリムカバーすなわち表皮材６およびワディング７、銀（Ａｇ）添加繊維１３、シートフレーム９を介して車体１２へ逃がすことができる。 According to the vehicle seat of the present embodiment, as in the first or second embodiment, static electricity generated between the occupant, that is, the occupant's clothing 10 and the seat cushion, is removed from the occupant (occupant's clothing) and the trim cover. That is, it can escape to the vehicle body 12 through the skin material 6 and the wadding 7, the silver (Ag) added fiber 13, and the seat frame 9.
　また、銀（Ａｇ）添加繊維１３に含まれる銀（Ａｇ）は抗菌性、消臭効果を有しており、シートクッションにおける菌の増殖を抑えることができる。 Further, silver (Ag) contained in the silver (Ag) -added fiber 13 has antibacterial and deodorizing effects, and can suppress the growth of bacteria in the seat cushion.
　さらに、本実施例のシートは、従来のウレタンパッド８の部分が全て銀（Ａｇ）添加繊維１３により形成されているため、従来のウレタンパッドに比べて、通気性の点においても優れている。また、銀（Ａｇ）添加繊維１３の素材のベースとなっている繊維はウレタンパッドに比べて重量が軽いため、シートの重量を２割から３割程度軽量化することができる。 Furthermore, the sheet of this example is superior in terms of air permeability as compared with the conventional urethane pad because the portion of the conventional urethane pad 8 is entirely formed of silver (Ag) -added fibers 13. Moreover, since the fiber which is the base of the material of the silver (Ag) -added fiber 13 is lighter than the urethane pad, the weight of the sheet can be reduced by about 20 to 30%.
　従って、通気性及びクッション性を損なうことなく、静電気の発生を抑え、抗菌性・消臭効果に優れた車両用シートを実現することが可能となる。 Therefore, it is possible to realize a vehicle seat that suppresses the generation of static electricity and has excellent antibacterial and deodorizing effects without impairing air permeability and cushioning properties.
　なお、本実施例においても、上記で説明したように、従来のウレタンパッド８の部分を全て銀（Ａｇ）添加繊維１３に置き換えてシートバック３に用いることにより、シートクッション同様にシートバックの静電気の発生を抑え、通気性、抗菌性・消臭効果を得ることができる。 Also in this embodiment, as described above, by replacing the conventional urethane pad 8 part with the silver (Ag) -added fiber 13 and using it for the seat back 3, the static electricity of the seat back is similar to the seat cushion.
