Abstract

PROBLEM TO BE SOLVED: To warm or cool an occupant while minimizing power to be consumed by a seat.SOLUTION: Noise generated when a vehicle travels enters through an opening section 22 and reaches a closed section 24 through a gap section 26b. The noise propagating to a stack section 26 compresses a gas in a temperature control member 20, resulting in formation of a warming section 32 in one side of the stack section 26. Additionally, a gas propagating to the opening section 22 from the closed section 24 expands, resulting in formation of a cooling section 30 in the other side of the stack section 26 different from the one side. A warming state of the warming section 32 or a cooling state of the cooling section 30 can be transferred to the occupant.

特開平8−20225号公報JP-A-8-20225

ところで公知技術の構成は、乗員の加温に比較的多くの電力を必要とすることから、シートの省電力化にはやや不向きな構成であった。とくに公知技術の構成は、電気的に走行可能な車両(電気自動車(EV)やハイブリット自動車(HV)など)の燃費を考慮すると、すんなり採用できる構成ではなかった。
本発明は上述の点に鑑みて創案されたものであり、本発明が解決しようとする課題は、シートの電力消費を極力抑えつつ、乗員を加温又は加冷可能とすることにある。
By the way, the configuration of the known technique requires a relatively large amount of electric power for heating the occupant, and thus is somewhat unsuitable for power saving of the seat. In particular, the configuration of the known technology is not a configuration that can be easily adopted in consideration of the fuel consumption of an electrically travelable vehicle (such as an electric vehicle (EV) or a hybrid vehicle (HV)).
The present invention has been devised in view of the above points, and a problem to be solved by the present invention is to enable a passenger to be heated or cooled while suppressing power consumption of the seat as much as possible.

上記課題を解決するための手段として、第1発明の車両用シートは、加温又は加冷により乗員体温を調整可能な温調部材を有する。この種のシート構成では、電力消費を極力抑えつつ、乗員を加温又は加冷できることが望ましい。
本発明では、上述の温調部材が中空の筒状であり、開口部と、閉鎖部と、スタック部を有する。閉鎖部は、温調部材の一側に設けられ、開口部は、一側とは異なる温調部材の他側に設けられる。そして開口部と閉鎖部の間にスタック部が設けられる。
As means for solving the above-mentioned problems, the vehicle seat of the first invention has a temperature adjusting member capable of adjusting the occupant body temperature by heating or cooling. In this type of seat configuration, it is desirable to be able to heat or cool the occupant while minimizing power consumption.
In this invention, the above-mentioned temperature control member is a hollow cylinder shape, and has an opening part, a closing part, and a stack part. The closing portion is provided on one side of the temperature adjustment member, and the opening is provided on the other side of the temperature adjustment member different from the one side. A stack portion is provided between the opening portion and the closing portion.

そこで本発明では、上述のスタック部が、温調部材内に収納される収納構造体と、収納構造体内に形成される隙間部とを有する。そして車両走行時などに発生する騒音が、開口部から侵入して隙間部を通り閉鎖部に到達する構成とする。このときスタック部に向かう騒音によって、温調部材内の気体を圧縮することにより、スタック部一側に加温部が形成される。また閉鎖部から開口部に向かう気体が膨張することで、一側とは異なるスタック部他側に加冷部が形成される。
そして本発明では、加温部の加温状態又は加冷部の加冷状態を乗員に伝達可能である。このように車両走行時などに発生する騒音を利用して、乗員を加温又は加冷可能としたことにより、シートの電力消費を極力抑えることができる。
So, in this invention, the above-mentioned stack part has the storage structure accommodated in a temperature control member, and the clearance gap part formed in a storage structure. And it is set as the structure which the noise which generate | occur | produces at the time of vehicle travel, etc. penetrate | invades from an opening part, and reaches | attains a closed part through a clearance gap part. At this time, the heating part is formed on one side of the stack part by compressing the gas in the temperature control member by the noise toward the stack part. Moreover, the gas which goes to an opening part from a closed part expand | swells, and a cooling part is formed in the stack part other side different from one side.
And in this invention, the heating state of a heating part or the cooling state of a cooling part can be transmitted to a passenger | crew. Thus, by making use of the noise generated when the vehicle travels, the passenger can be heated or cooled, so that the power consumption of the seat can be suppressed as much as possible.

第2発明の車両用シートは、第1発明の車両用シートであって、車両用シートが切替え部材を備えて、加温部の加温状態又は加冷部の加冷状態を選択して乗員に伝達可能である(より使い勝手のよい構成である)。   The vehicle seat of the second invention is the vehicle seat of the first invention, wherein the vehicle seat is provided with a switching member, and selects a heating state of the heating unit or a cooling state of the cooling unit, and a passenger (It is a more user-friendly configuration).

本発明の第1発明によれば、シートの電力消費を極力抑えつつ、乗員を加温又は加冷することができる。また第2発明によれば、より使い勝手の良いシート構成となる。   According to the first aspect of the present invention, the occupant can be heated or cooled while suppressing the power consumption of the seat as much as possible. According to the second aspect of the invention, the seat configuration is more convenient.

そこで本実施例では、後述の構成(温調部材20,伝達部材40)により、シートの電力消費を極力抑えつつ、乗員を加温又は加冷することとした。以下、各構成について詳述する。
<Example 1>
The vehicle seat 2 of the present embodiment includes a heater member 10, a temperature adjustment member 20, and a transmission member 40 (see FIG. 4). The heater member 10 is a zigzag linear member (for example, nichrome wire), and can generate heat by supplying power.
In this embodiment, the heater member 10 is electrically connected to an in-vehicle power source (not shown) after the heater member 10 is disposed between the cushion material 6P and the skin material 6S. Then, the occupant is heated by the heater member 10. In this type of seat configuration, it is desirable that the occupant can be heated while suppressing the power consumption of the seat as much as possible.
Therefore, in this embodiment, the occupant is heated or cooled while suppressing the power consumption of the seat as much as possible by the later-described configurations (the temperature adjustment member 20 and the transmission member 40). Hereinafter, each configuration will be described in detail.

[温調部材]
温調部材20は、加温又は加冷により乗員体温を調整可能な部材である(図1〜図3を参照)。本実施例の温調部材20は、上部フレーム6a(中空の筒状部材)であり、開口部22と、閉鎖部24と、スタック部26と、加温部32と、加冷部30を有する。
閉鎖部24は、シート外部に非開放の部位であり、上部フレーム6aの一端側に設けることができる。また開口部22は、シート外部に開放される部位(騒音の侵入を許容する部位)であり、一端側とは異なる上部フレーム6aの他端側に設けることができる。そして開口部22と閉鎖部24の間に後述のスタック部26が設けられる。
なお温調部材20は、むき出しのままシート内に配設することもできるが、断熱性を有する被覆部材(図示省略)で被覆することが望ましい。
[Temperature control member]
The temperature adjustment member 20 is a member capable of adjusting the occupant body temperature by heating or cooling (see FIGS. 1 to 3). The temperature adjustment member 20 of the present embodiment is an upper frame 6a (hollow cylindrical member), and has an opening 22, a closing part 24, a stack part 26, a heating part 32, and a cooling part 30. .
The closing part 24 is a non-opening part outside the seat, and can be provided on one end side of the upper frame 6a. Further, the opening 22 is a portion opened to the outside of the seat (a portion allowing noise intrusion), and can be provided on the other end side of the upper frame 6a different from the one end side. A stack portion 26 described later is provided between the opening portion 22 and the closing portion 24.
The temperature adjusting member 20 can be disposed in the sheet as it is exposed, but it is desirable to cover it with a covering member (not shown) having heat insulating properties.

(スタック部)
スタック部26は、収納構造体(26a)と、隙間部26bを有する(図2を参照)。
収納構造体は、温調部材20内に収納可能な構造体であり、複数の棒状部材、板状の構造体及びハニカム構造体を例示できる。収納構造体の材質は特に限定しないが、例えばステンレス等の金属、ポリイミド等の樹脂、セラミックを例示できる。
本実施例では、収納構造体26aとして、円筒状のステンレス管(外径2mm、内径1.6mm)又はポリイミド製の円筒状の細管(外径1mm)を用いる。そして複数の収納構造体26aの束を上部フレーム6a途中に収納(充填)するとともに、複数の収納構造体26aの間に複数の隙間部26bを形成する。
(Stack part)
The stack part 26 has a storage structure (26a) and a gap part 26b (see FIG. 2).
The storage structure is a structure that can be stored in the temperature control member 20, and examples thereof include a plurality of rod-shaped members, a plate-shaped structure, and a honeycomb structure. Although the material of a storage structure is not specifically limited, For example, metals, such as stainless steel, resin, such as a polyimide, and a ceramic can be illustrated.
In this embodiment, a cylindrical stainless steel tube (outer diameter 2 mm, inner diameter 1.6 mm) or a polyimide cylindrical tube (outer diameter 1 mm) is used as the storage structure 26a. A bundle of a plurality of storage structures 26a is stored (filled) in the middle of the upper frame 6a, and a plurality of gaps 26b are formed between the plurality of storage structures 26a.

隙間部26bは、気体の流通可能な流路であり、収納構造体26aの一側と他側を連通する(図2を参照)。隙間部26bは、温調部材20の内径よりも小さい流路寸法を有する。
そして車両走行時などに発生する騒音が、開口部22から侵入して隙間部26bを通り閉鎖部24に到達する。このとき温調部材20内の気体が圧縮又は膨張することで、温調部材20に、後述の加温部32と加冷部30が形成される。
The gap portion 26b is a flow path through which gas can flow, and communicates one side and the other side of the storage structure 26a (see FIG. 2). The gap portion 26 b has a flow path dimension smaller than the inner diameter of the temperature adjustment member 20.
Noise generated when the vehicle travels enters from the opening 22 and reaches the closing portion 24 through the gap 26b. At this time, a gas in the temperature adjustment member 20 is compressed or expanded, whereby a heating unit 32 and a cooling unit 30 described later are formed in the temperature adjustment member 20.

(加温部・加冷部)
加温部32とは、上部フレーム6aの常温(積極的に加温及び加却されないときの温度)よりも高い温度を有する部位(加温状態となる部位)である(図2〜図4を参照)。また加冷部30とは、上部フレーム6aの常温よりも低い温度を有する部位(加冷状態となる部位)である。
本実施例では、温調部材20に騒音が入ると、温調部材20内に1/4波長の定在波ができて、スタック部26一側(閉鎖部24寄り)で温度が上がり、スタック部26他側(開口部22寄り)で温度が下がる。これはスタック部26内の気体の小さな部分に注目すると、気体塊は音波により圧力の高いスタック部26一側に移動させられ圧縮されて体積が小さくなる。このとき断熱圧縮で温度が上がるが近くのスタック部26(収納構造体)の壁面に放熱して温度が少し下がる。先ほどの温度が高い側でスタック部26に放熱して温度が下がった分だけ周囲より温度が低くなる。この微小サイクルがスタック部26(収納構造体)に沿って連なってバケツリレーで熱を運び、結局スタック部26他側が最も低温になり(加冷部30が形成され)、一側が最も高温になる(加温部32が形成される)。
(Heating / cooling part)
The heating part 32 is a part (part which becomes a warming state) having a temperature higher than the normal temperature of the upper frame 6a (temperature when not actively heated and rejected) (see FIGS. 2 to 4). reference). The cooling unit 30 is a part having a temperature lower than the room temperature of the upper frame 6a (part to be cooled).
In this embodiment, when noise enters the temperature adjustment member 20, a ¼ wavelength standing wave is generated in the temperature adjustment member 20, and the temperature rises on one side of the stack portion 26 (closer to the closing portion 24). The temperature falls on the other side of the portion 26 (closer to the opening 22). When attention is paid to a small portion of the gas in the stack portion 26, the gas mass is moved to one side of the stack portion 26 having a high pressure by sound waves and compressed to reduce the volume. At this time, the temperature rises due to adiabatic compression, but heat is radiated to the wall surface of the nearby stack portion 26 (housing structure), and the temperature is lowered a little. The temperature becomes lower than that of the surroundings by the amount of heat that is released from the stack 26 on the higher temperature side. This micro cycle continues along the stack part 26 (housing structure) and carries heat by the bucket relay, and eventually the other side of the stack part 26 has the lowest temperature (the cooling part 30 is formed), and one side has the highest temperature. (The heating part 32 is formed).

(スタック部の配設)
スタック部26の配設方法は特に限定しない。例えば図3を参照して、上部フレーム6a内にスタック部26を挿入したのち、所定の場所に固定することができる。
また図5を参照して、上部フレーム6aを三分割して、第一筒体16aと、第二筒体16bと、第三筒体16cを形成する。そして第一筒体16aの他端に開口部22を形成するとともに、一端に、径方向外に張出すフランジ部17aを形成する。また第二筒体16bの一端に閉鎖部24を形成するとともに、他端に、径方向外に張出すフランジ部17bを形成する。そして第三筒体16c(比較的短尺)にスタック部26を充填するとともに、両端に、おのおの径方向外に張出すフランジ部17cを形成する。
そして各筒体のフランジ部17a〜17cに、ボルト部材Vを挿入可能なボルト孔Hを設ける。つぎに各フランジ部17a〜17cを面接触させたのち(ボルト孔H同士を合わせたのち)、各筒体16a〜16c同士を、ボルト部材Vで接合することで温調部材20を形成することができる。
(Arrangement of stack part)
The arrangement | positioning method of the stack part 26 is not specifically limited. For example, referring to FIG. 3, after inserting the stack portion 26 into the upper frame 6a, the stack portion 26 can be fixed at a predetermined place.
Further, referring to FIG. 5, the upper frame 6a is divided into three parts to form a first cylinder 16a, a second cylinder 16b, and a third cylinder 16c. And while forming the opening part 22 in the other end of the 1st cylinder 16a, the flange part 17a projected outside in a radial direction is formed in one end. In addition, a closing portion 24 is formed at one end of the second cylindrical body 16b, and a flange portion 17b projecting radially outward is formed at the other end. Then, the third cylindrical body 16c (relatively short) is filled with the stack portion 26, and flange portions 17c are formed at both ends so as to protrude outward in the radial direction.
And the bolt hole H which can insert the bolt member V is provided in the flange parts 17a-17c of each cylinder. Next, after making each flange part 17a-17c surface-contact (after match | combining bolt holes H), the temperature control member 20 is formed by joining each cylinder 16a-16c with the bolt member V. FIG. Can do.

ここで温調部材20内におけるスタック部26の配設位置は、車両走行時などに発生する騒音(波長、周波数)によって適宜変更できる(図3を参照)。
このときスタック部26を、閉鎖部24寄りに配設することが望ましい。例えば長さ寸法(L)の温調部材20を使用する場合、スタック部26を、離間寸法(x)だけ閉鎖部24から離間させる。そして温調部材20の長さ寸法に対する離間寸法の割合(x/L×100)を30%〜40%程度に設定することで、温調部材20(加温部32)の熱量を最大とする(熱輸送量を最大とする)ことができる。
Here, the arrangement position of the stack portion 26 in the temperature control member 20 can be changed as appropriate according to noise (wavelength, frequency) generated during traveling of the vehicle (see FIG. 3).
At this time, it is desirable to dispose the stack portion 26 closer to the closing portion 24. For example, when using the temperature control member 20 having the length dimension (L), the stack part 26 is separated from the closing part 24 by the separation dimension (x). And the ratio (x / Lx100) of the separation dimension with respect to the length dimension of the temperature control member 20 is set to about 30% to 40%, thereby maximizing the amount of heat of the temperature control member 20 (heating unit 32). (Maximum heat transport).

[伝達部材]
伝達部材40は、温調部材20の加温状態又は加冷状態を乗員に伝達する部材である(図4を参照)。本実施例の伝達部材40は、表皮材6Sと、接続部材42を有する。接続部材42は、熱伝導性を有する線状部材(例えばニクロム線)である。
本実施例では、熱伝線材と、熱伝線材とは異なる他の線材により、表皮材6Sとしての布帛を作成する。ここで熱伝線材は、熱を伝達可能な線材であり、金属線(例えば金属や合金などの導電糸)や金属メッキを施した線材を例示できる。他の線材(材質)は、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。
つぎにクッション材6Pを表皮材6Sで被覆するとともに、加温部32を、接続部材42を介して表皮材6S(熱伝線材)につなげる。そして後述するように、加温部32の加温状態を、表皮材6S及び接続部材42を介して乗員に伝達する。
[Transmission member]
The transmission member 40 is a member that transmits the heating state or the cooling state of the temperature adjustment member 20 to the occupant (see FIG. 4). The transmission member 40 of the present embodiment includes a skin material 6S and a connection member 42. The connecting member 42 is a linear member (for example, nichrome wire) having thermal conductivity.
In the present embodiment, a fabric as the skin material 6S is made of a heat transfer wire and another wire different from the heat transfer wire. Here, the heat transfer wire is a wire that can transfer heat, and can be exemplified by a metal wire (for example, a conductive yarn such as metal or alloy) or a wire plated with metal. Examples of other wires (materials) include plant-based and animal-based natural fibers, chemical fibers made of thermoplastic resins or thermosetting resins, and blended fibers thereof.
Next, the cushion material 6 </ b> P is covered with the skin material 6 </ b> S, and the heating portion 32 is connected to the skin material 6 </ b> S (heat transfer wire material) via the connection member 42. Then, as will be described later, the heating state of the heating unit 32 is transmitted to the occupant via the skin material 6S and the connection member 42.

(乗員の加温又は加冷)
図1及び図4を参照して、車両用シート2周囲で各種騒音(車両走行時の騒音、音響機器の騒音、外部の騒音等)が発生する。このとき本実施例では、各種騒音が開口部22を介して、上部フレーム6a(温調部材20)内に侵入する。
そしてスタック部26に向かう騒音によって、温調部材20内の気体を圧縮することにより、スタック部26の一側に加温部32が形成される。そして加温部32の加温状態が、伝達部材40(接続部材42及び表皮材6S)を介して乗員に伝達することで、乗員を加温することができる。このように本実施例では、温調部材20により乗員を加温することができるため、ヒータ部材10を非通電状態としたり、ヒータ部材10の設定温度を低く設定したりすることができる(シートの省電力化が図られる)。
(Crew heating or cooling)
Referring to FIGS. 1 and 4, various noises (such as noise during vehicle traveling, noise from audio equipment, external noise, etc.) are generated around vehicle seat 2. At this time, in this embodiment, various noises enter the upper frame 6a (temperature control member 20) through the opening 22.
And the heating part 32 is formed in the one side of the stack part 26 by compressing the gas in the temperature control member 20 by the noise which goes to the stack part 26. And the passenger | crew can be heated by transmitting the heating state of the heating part 32 to a passenger | crew via the transmission member 40 (connecting member 42 and skin material 6S). Thus, in the present embodiment, since the passenger can be heated by the temperature adjustment member 20, the heater member 10 can be in a non-energized state, or the set temperature of the heater member 10 can be set low (seat) Power saving).

また本実施例では、閉鎖部24で反射した騒音により、閉鎖部24から開口部22に向かって気体が膨張されることで、スタック部26他側に加冷部30が形成される。
そこで加冷部30を、接続部材42を介して表皮材6S(熱伝線材)につなげる。こうすることで加冷部30の加冷状態が、接続部材42及び表皮材6S(伝達部材40)を介して乗員に伝達される(乗員を加冷することができる)。例えば夏場においては、表皮材6S(熱伝線材)に蓄熱された熱を、接続部材40を介して加冷部30によって吸熱することができ、表皮材6Sの温度を下げることができる。
Further, in the present embodiment, the gas is expanded from the closing portion 24 toward the opening portion 22 by the noise reflected by the closing portion 24, thereby forming the cooling portion 30 on the other side of the stack portion 26.
Therefore, the cooling unit 30 is connected to the skin material 6S (heat conductor) via the connection member 42. By doing so, the cooling state of the cooling unit 30 is transmitted to the occupant via the connection member 42 and the skin material 6S (transmission member 40) (the occupant can be cooled). For example, in summer, the heat stored in the skin material 6S (heat transfer material) can be absorbed by the cooling unit 30 via the connection member 40, and the temperature of the skin material 6S can be lowered.

以上説明したとおり本実施例では、車両走行時などに発生する騒音を利用して、乗員を加温又は加冷可能であることから、シートの電力消費を極力抑えることができる。
また本実施例では、上部フレーム6a(車両用シート2の既存構成)を温調部材20に利用することから、シート構成をシンプル化できる。
また本実施例では、騒音のエネルギーを熱エネルギーに変換することにより、車室内の騒音を低減することができる(消音性能に優れるシート構成である)。
また本実施例では、温調部材20(一つの部材)で乗員を加温又は加冷することができる。このめた車両用シート2の部品点数の増加を極力抑えることができるとともに、季節を問わず(例えば一年中)温調部材20を活用することができる。
そして本実施例では、表皮材6S(乗員に近接又は当接する部材)に温調部材20の加温状態(加冷状態)を伝達できるため、より効率良く乗員を加温(加冷)できる。
As described above, in the present embodiment, the passenger can be heated or cooled using noise generated when the vehicle travels, and therefore, the power consumption of the seat can be suppressed as much as possible.
In this embodiment, the upper frame 6a (the existing configuration of the vehicle seat 2) is used for the temperature adjustment member 20, so that the seat configuration can be simplified.
In this embodiment, the noise in the vehicle cabin can be reduced by converting the energy of noise into heat energy (the seat configuration is excellent in silencing performance).
In this embodiment, the occupant can be heated or cooled by the temperature adjustment member 20 (one member). The increase in the number of parts of the vehicle seat 2 can be suppressed as much as possible, and the temperature control member 20 can be used regardless of the season (for example, all year round).
And in a present Example, since the heating state (cooling state) of the temperature control member 20 can be transmitted to the skin material 6S (member which adjoins or contacts a passenger | crew), a passenger | crew can be heated (cooled) more efficiently.

ところで一般的に、車両用シート2に乗員が着座することで、乗員腰部が、車両用シート2に押し付けられた状態となる一方、乗員背部は、やや浅く当接した状態となる。このためシートの快適性等を考慮すると、乗員腰部を速やかに加温することが好ましい一方、乗員背部を比較的ゆっくり加温できればよい。
そこで本実施例では、ヒータ部材10を、シートバック6下部位置(乗員腰部に相当する位置)に配設することで乗員腰部を速やかに加温する。
また第二の線状部材44を、シートバック6上部位置(乗員背部に相当する位置)に配設する。そして車両走行時に発生する各種騒音等により、スタック部26の一側に加温部32が形成される。そして加温部32の加温状態が、接続部材42を介して第二の線状部材44に熱伝導で伝わることで、乗員背部をゆっくり加温することができる。
By the way, generally, when an occupant sits on the vehicle seat 2, the occupant waist is pressed against the vehicle seat 2, while the occupant back is in a slightly shallow contact state. For this reason, considering the comfort of the seat and the like, it is preferable to quickly heat the occupant waist, but it is only necessary to heat the occupant back relatively slowly.

The second linear member 44 is disposed at the upper position of the seat back 6 (position corresponding to the back of the passenger). And the heating part 32 is formed in the one side of the stack part 26 by the various noise etc. which generate | occur | produce during vehicle travel. And the passenger | crew's back part can be heated slowly because the heating state of the heating part 32 is transmitted to the 2nd linear member 44 through the connection member 42 by heat conduction.

このように本実施例では、シートバック6上部(車両用シート2一部)を温調部材20で加温する。よってヒータ部材10の配設面積が減少するため、シートの電力消費を極力抑えることができる。
また本実施例では、比較的速やかに乗員腰部を加温できるとともに、乗員背部をゆっくり加温できる(使い勝手のよいシート構成である)。
Thus, in the present embodiment, the upper portion of the seat back 6 (a part of the vehicle seat 2) is heated by the temperature adjustment member 20. Therefore, since the arrangement area of the heater member 10 is reduced, the power consumption of the seat can be suppressed as much as possible.

However, the configuration of the temperature control member is not intended to be limited. For example, a temperature control member separate from the seat structure can be attached to the vehicle seat 2.
And since a temperature control member is a different body from a sheet | seat structure, structures, such as a length dimension, can be changed suitably. Here, main frequencies of noise (road noise) during typical vehicle travel are 250 Hz and 315 Hz.
Therefore, for example, referring to FIG. 3, the length dimension (L) of the temperature control member 20 is set to 34 cm, and the separation dimension (x) between the stack part 26 and the closing part 24 is set to 10.2 to 13.6 cm.

(3) Moreover, in this embodiment, the example which uses the skin material 4S and the 2nd linear member 44 as the transmission member 40 was demonstrated. Unlike this, the temperature control member 20 can be connected to the heater member 10 (the heater member 10 is used as a transmission member). In summer and the like, the non-energized heater member 10 may have heat. In such a case, the heater member 10 and the cooling unit 30 can be connected.

(4)また本実施形態では、専らシートバック6に温調部材20を配設する例を説明した。本実施例の構成は、シートクッション4、レール部材9F等の各種シート構成に適用可能である。例えば補強部材4cや操作部9cを温調部材として使用することができる(図1を参照)。またレール部材9Fが所定の密閉性を有する場合には温調部材として使用することができる。
(5)また本実施例では、ヒータ部材10を備える車両用シート2を例示した。これとは異なりクーラ部材(電力を供給することで乗員を加冷可能な部材)を備える車両用シートに、温調部材を設けることができる。
(6)また本実施例では、切替え部材の一構成を例示したが、切替え部材の構成を限定する趣旨ではない。例えば押しボタン式の切替え部材を用いることができる。
(4) Moreover, in this embodiment, the example which arrange | positions the temperature control member 20 exclusively in the seat back 6 was demonstrated. The configuration of the present embodiment is applicable to various seat configurations such as the seat cushion 4 and the rail member 9F. For example, the reinforcement member 4c and the operation part 9c can be used as a temperature control member (refer FIG. 1). Further, when the rail member 9F has a predetermined sealing property, it can be used as a temperature control member.
(5) Moreover, in the present Example, the vehicle seat 2 provided with the heater member 10 was illustrated. Unlike this, a temperature control member can be provided on a vehicle seat including a cooler member (a member capable of cooling an occupant by supplying electric power).
(6) In the present embodiment, the configuration of the switching member is illustrated, but the configuration of the switching member is not limited. For example, a push button type switching member can be used.
