　開口形成片１１は、シートクッション２の着座面に沿って延在する板状の部材である。開口形成片１１には、シート１に着座した乗員の臀部から大腿部に対応する部分に沿って、列をなすように複数の開口部１２が設けられている。開口部１２が車室内に連通するように、表皮材８の開口部１２に整合する部分は、織布等の通気性を有する素材からなるか、又は、各々の開口部１２の少なくとも一部に整合するように設けられた孔（図示せず）を有する。 The opening forming piece 11 is a plate-like member extending along the seating surface of the seat cushion 2. The opening forming piece 11 is provided with a plurality of openings 12 so as to form a row along the portion corresponding to the thigh from the buttocks of the occupant seated on the seat 1. The portion of the skin material 8 aligned with the opening 12 so that the opening 12 communicates with the vehicle interior is made of a material having air permeability such as a woven fabric, or at least a part of each opening 12. It has a hole (not shown) provided to align.
　配風通路形成片１０は、板状の部材である。配風通路形成片１０は、配風通路形成片１０を上下方向に貫通するように設けられた、一繋がりの溝を有し、この溝がパッド本体９と開口形成片１１とに挟まれることによって、開口部１２に連通する配風通路１３が形成される。配風通路１３は、複数の開口部１２が並んだ方向に沿って延在する２つの流入部１３ａと、２つの流入部をその後端側で連結する連結部１３ｂと、連結部の後方に設けられた１つの流出部１３ｃとを有する。開口部１２が複数設けられ、配風通路１３の流入部１３ａがその全ての開口部１２に連通することによって、乗員の臀部から脚部にかけての広範囲から生体ガスを含む気体を収集することができる。 The air distribution passage forming piece 10 is a plate-like member. The air distribution passage forming piece 10 has a continuous groove provided so as to penetrate the air distribution passage forming piece 10 in the vertical direction, and the groove is sandwiched between the pad main body 9 and the opening forming piece 11. Thus, the air distribution passage 13 communicating with the opening 12 is formed. The air distribution passage 13 is provided in the rear of the two inflow portions 13a extending along the direction in which the plurality of openings 12 are arranged, a connection portion 13b for connecting the two inflow portions on the rear end side, and the connection portion. One outflow portion 13c. A plurality of openings 12 are provided, and the inflow portion 13a of the air distribution passage 13 communicates with all of the openings 12, so that a gas containing biological gas can be collected from a wide range from the occupant's buttocks to the legs. .
　パッド本体９は、上下方向に於いて流出部１３ｃに整合する位置に、上下方向に貫通する連通孔１４が設けられている。開口部１２、配風通路１３及び連通孔１４を画成する壁面は、パッド７を構成する空隙の多い素材からなるため、これらの壁面を非通気性に加工することが好ましい。 The pad main body 9 is provided with a communication hole 14 penetrating in the vertical direction at a position aligned with the outflow portion 13c in the vertical direction. Since the wall surface that defines the opening 12, the air distribution passage 13, and the communication hole 14 is made of a material having many voids constituting the pad 7, it is preferable that these wall surfaces be processed to be non-breathable.
　シートクッション２に設けられた開口部１２、配風通路１３及び連通孔１４と同様の構成が、シートバック３にも設けられる。シートバック３の開口部１２は、シート１に着座した乗員の背中に沿って延在する。シートバック３の配風通路１３及び連通孔１４の形状や、開口部１２に対する配置及び向きは、シートクッション２に設けられたものと同様であるため、図示及び詳細な説明を省略する。なお、開口部１２、配風通路１３及び連通孔１４をシートクッション２にのみ設けるように変更してもよく、これらをシートバック３にのみ設けるように変更してもよい。 The same configuration as the opening 12, the air distribution passage 13 and the communication hole 14 provided in the seat cushion 2 is also provided in the seat back 3. The opening 12 of the seat back 3 extends along the back of the occupant seated on the seat 1. Since the shape of the air distribution passage 13 and the communication hole 14 of the seat back 3 and the arrangement and orientation with respect to the opening 12 are the same as those provided in the seat cushion 2, illustration and detailed description thereof are omitted. The opening 12, the air distribution passage 13, and the communication hole 14 may be changed so as to be provided only in the seat cushion 2, or may be changed so as to be provided only in the seat back 3.
　シートクッション２の連通孔１４には、第１ダクト管１５の一端側が接続されている。第１ダクト管１５の連通孔１４に取り付けられた端部は、取付を容易にするため、また、シートクッション２の振動を許容できるようにするため、可撓性を有する蛇腹状になっていることが好ましい。また、シートバック３の連通孔１４には、第２ダクト管１６の一端側が接続されている（図示せず）。第２ダクト管１６の他端側は、第１ダクト管１５の中間部１５ａに接続されており、第２ダクト管１６の内部は、第１ダクト管１５の内部に連通しているため、シートバック３の開口部１２から流入した気体が、シートクッション２の開口部１２から流入した気体に合流する。 One end side of the first duct pipe 15 is connected to the communication hole 14 of the seat cushion 2. The end portion attached to the communication hole 14 of the first duct pipe 15 has a flexible bellows shape in order to facilitate attachment and to allow vibration of the seat cushion 2. It is preferable. Further, one end side of the second duct pipe 16 is connected to the communication hole 14 of the seat back 3 (not shown). The other end side of the second duct pipe 16 is connected to the intermediate portion 15a of the first duct pipe 15, and the inside of the second duct pipe 16 communicates with the inside of the first duct pipe 15, so that the seat The gas flowing in from the opening 12 of the back 3 merges with the gas flowing in from the opening 12 of the seat cushion 2.
　第１ダクト管１５の他端側は、送風機１７が内部に設置された送風室１８に接続されている。送風室１８と集気室５とは、第３ダクト管１９が両者に接続されることで、互いに内部が連通している。送風機１７は、開口部１２を上流側とし、集気室５を下流側とするように気体を流す。 The other end of the first duct pipe 15 is connected to a blower chamber 18 in which a blower 17 is installed. The interior of the air blowing chamber 18 and the air collecting chamber 5 is in communication with each other by connecting the third duct pipe 19 to both. The blower 17 flows gas so that the opening 12 is on the upstream side and the air collecting chamber 5 is on the downstream side.
　配風通路１３、連通孔１４、第１ダクト管１５の内部、第２ダクト管１６の内部、送風室１８の内部、及び第３ダクト管１９の内部が、開口部１２から集気室５に至る通気路２０を構成する。集気室５には、送られてきた気体を排出する排出口に圧力弁（図示せず）が設けられており、集気室５では、気体が圧縮されて、生体ガスの成分濃度が高められる。 The air distribution passage 13, the communication hole 14, the inside of the first duct pipe 15, the inside of the second duct pipe 16, the inside of the blower chamber 18, and the inside of the third duct pipe 19 are moved from the opening 12 to the air collecting chamber 5. To reach the ventilation path 20. The air collection chamber 5 is provided with a pressure valve (not shown) at the discharge port for discharging the sent gas. In the air collection chamber 5, the gas is compressed to increase the component concentration of the biological gas. It is done.
　ガス検知センサ２１は、集気室５に配置されており、車内に設けられたＥＣＵ２２に検知したガスの情報を送信することができる。ＥＣＵ２２は、受信した情報を分析して、分析結果を、スピーカー（音声又は警報）やディスプレイ等の車室内に設置された出力手段（図示せず）に出力し、又は、携帯型又は固定型の情報端末に送信することができる。 The gas detection sensor 21 is disposed in the air collecting chamber 5 and can transmit information of the detected gas to the ECU 22 provided in the vehicle. The ECU 22 analyzes the received information and outputs the analysis result to output means (not shown) installed in the vehicle interior such as a speaker (sound or alarm) or a display, or a portable or fixed type. It can be transmitted to the information terminal.
　人の体調や病気と、体臭として分泌されるにおい及びにおいの主成分との間には関連がある。例えば、糖尿病を患っているときや体脂肪が燃焼しているときは、甘い匂いの体臭がして、その主成分はケトン体（アセトン）である。胃の障害があるときは、卵が腐ったような体臭がして、その主成分は、硫化水素である。胃や肝臓の機能に障害があるときは、アンモニア臭、ねずみ臭又はどぶ臭のような体臭がして、その主成分はアンモニアである。がんの人は、化学調味料や腐ったにおいの体臭がして、その主成分は、メタンチオールやＶＳＣ（揮発性硫黄化合物）であり、その他の成分も含まれるが明らかになっていない。二日酔いのときは、アルコール臭の体臭がして、その主成分はアセトアルデヒドである。疲労しているときは、アンモニア臭の体臭がして、その主成分はアンモニアである。てんかんの人には、腐ったにおいの体臭がするといわれているが、その主成分は明らかになっていない。 There is a relationship between a person's physical condition and illness and the odor secreted as body odor and the main component of the odor. For example, when suffering from diabetes or when body fat is burning, the body smells sweet and its main component is a ketone body (acetone). When there is a stomach disorder, the body smells like rotten eggs and its main component is hydrogen sulfide. When there is a disorder in the function of the stomach or liver, there is a body odor such as an ammonia odor, a mouse odor or a stink odor, and its main component is ammonia. People with cancer have a chemical seasoning or rotten odor, and the main components are methanethiol and VSC (volatile sulfur compounds), which contain other components, but it has not been clarified. In the case of a hangover, there is a body odor of alcohol odor, and its main component is acetaldehyde. When tired, the body smells like ammonia and its main component is ammonia. People with epilepsy are said to have a rotten smell of body odor, but the main ingredient is not clear.
　ガス検知センサ２１は、乗員の口、鼻、皮膚、肛門等から排出された気体成分、すなわち、生体ガスの種類及び濃度を検地して、その結果をＥＣＵ２２に送る。ＥＣＵ２２は、その結果を分析し、上述のような体調及び症状と気体成分との関係に基づき、乗員の健康状態を判断し、必要に応じて出力する。ガス検知センサ２１として、例えば、電気化学式、半導体式、熱線式、赤外線吸収式、又は人口脂質膜式等のセンサを使用することができる。 The gas detection sensor 21 detects the gas component discharged from the passenger's mouth, nose, skin, anus, etc., that is, the type and concentration of the biological gas, and sends the result to the ECU 22. The ECU 22 analyzes the result, determines the health state of the occupant based on the relationship between the physical condition and symptoms as described above, and the gas component, and outputs it as necessary. As the gas detection sensor 21, for example, an electrochemical type, semiconductor type, heat ray type, infrared absorption type, artificial lipid membrane type sensor or the like can be used.
　皮膚から排出される生体ガスは微量であるが、開口部１２が、着座した乗員の体表面の近傍に位置するため、周囲の空気によって希釈される前に、微量な生体ガスを比較的高濃度で得ることができる。汗をかきやすい大腿部や背中を支持するべき部分の近傍に開口部１２を設けたことにより、汗に含まれる生体ガスを更に高濃度で得ることができる。また、シートクッション２の開口部１２の一部は、乗員の臀部を支持すべき位置の近傍にあるため、多様な成分を含んで多様な生体情報を得ることができる体内ガス（おなら）を高濃度で得ることができる。ガス検知センサ２１にガスクロマトグラフィを使用すれば、更に微量の生体ガスでも検知することができる。また、集気室５にフィルターを設けて、検知対象ガスを捕集してもよい。 Although the amount of biological gas discharged from the skin is very small, since the opening 12 is located in the vicinity of the body surface of the seated occupant, the biological gas is relatively high in concentration before being diluted with the surrounding air. Can be obtained at By providing the opening 12 in the vicinity of the thigh and the part that should support the back that are likely to sweat, the biogas contained in the sweat can be obtained at a higher concentration. Further, since a part of the opening 12 of the seat cushion 2 is in the vicinity of the position where the occupant's buttocks are to be supported, a body gas (fart) that can obtain various biological information including various components can be obtained. It can be obtained at a high concentration. If gas chromatography is used for the gas detection sensor 21, even a trace amount of biological gas can be detected. Further, a filter may be provided in the air collecting chamber 5 to collect the detection target gas.
　ガス検知センサ２１は、他の位置に設置することもできる。例えば、図１に二点鎖線で示すように、連通孔１４や、第１ダクト管１５（第２ダクト管１６又は第３ダクト管１９でも可）に取り付けてもよく、送風機１７に組み込んでもよい。連通孔１４に取り付けた場合は、車両が振動しても、パッド７によってその振動が吸収されるため、固定性が向上する。第１ダクト管１５に取り付けた場合は、管部材は容易に取り外すことができるため、ガス検知センサ２１のメンテナンスが容易となる（第２ダクト管１６又は第３ダクト管１９に取り付けた場合も同様）。送風機１７に組み込んだ場合は、電源を送風機１７と共有することができる。これらの場合は、集気室５は不要となる。 The gas detection sensor 21 can be installed at other positions. For example, as shown by a two-dot chain line in FIG. 1, it may be attached to the communication hole 14, the first duct pipe 15 (or the second duct pipe 16 or the third duct pipe 19), or may be incorporated into the blower 17. . When attached to the communication hole 14, even if the vehicle vibrates, the vibration is absorbed by the pad 7, so that the fixability is improved. When attached to the first duct pipe 15, the pipe member can be easily removed, so that the maintenance of the gas detection sensor 21 is facilitated (the same applies to the case where it is attached to the second duct pipe 16 or the third duct pipe 19). ). When incorporated in the blower 17, the power source can be shared with the blower 17. In these cases, the air collecting chamber 5 is not necessary.
　開口部１２、通気路２０及び送風機１７は、シート１の表面に対して空気を吸引又は送風することにより、汗むれを防止し、湿度を調整するエアーベンチレーションシステム（ＡＶＳ）と共通する構成であるため、効率的に、ガス検知機能及び湿度調整機能を車両に設けることができる。なお、エアーベンチレーションシステムに於いて、シート１の表面に対して空気を吸引する構成（プル式）のときは、送風機１７や通気路２０をそのまま使い、シート１の表面に対して空気を送風する構成（プッシュ式）のときは、送風機１７が軸流式等の逆回転によって反対方向に送風可能なものであればこれを逆回転させ、そうではない遠心式等のものであれば、切り替え用の送風経路を設け、又は他の送風機を設置する。 The opening 12, the air passage 20, and the blower 17 are configured in common with an air ventilation system (AVS) that prevents sweating and adjusts humidity by sucking or blowing air to the surface of the seat 1. Therefore, the gas detection function and the humidity adjustment function can be efficiently provided in the vehicle. In the air ventilation system, when the air is sucked to the surface of the sheet 1 (pull type), the air is blown to the surface of the sheet 1 by using the blower 17 and the air passage 20 as they are. If the blower 17 is capable of blowing air in the opposite direction by reverse rotation, such as an axial flow type, the rotation is reversed, and if it is not the centrifugal type, switching is performed A ventilation path is provided, or another blower is installed.
　シート１を用いた乗員の健康状態の確認は、車両の始動時に行われることが好ましく、運転時間の経過に伴う変化を確認するため、所定の間隔毎に、また、連続的に行ってもよい。開口部１２、通気路２０及び送風機１７等が、エアーベンチレーションシステムを兼ねる場合は、ガスの検知及び湿度の調整にそれぞれ最適な風量を設定するため、ガスの検知は、車両の始動時及び／又は所定の時間間隔毎に行われ、その他の時間に湿度調整を行えることが好ましい。 Confirmation of the health condition of the occupant using the seat 1 is preferably performed at the start of the vehicle, and may be performed at predetermined intervals or continuously in order to confirm changes with the passage of driving time. . When the opening 12, the air passage 20, the blower 17, etc. also serve as an air ventilation system, an optimum air volume is set for gas detection and humidity adjustment, respectively. Alternatively, it is preferably performed at predetermined time intervals, and humidity adjustment can be performed at other times.
　以上で具体的実施形態の説明を終えるが、本発明は上記実施形態に限定されることなく幅広く変形実施することができる。本発明に係るシートは、車両の助手席や後部座席のシートに適用してもよく、航空機等の車両以外の乗物のシートにも適用してもよい。開口部の位置をずらしてもよい。 This is the end of the description of the specific embodiment, but the present invention is not limited to the above-described embodiment, and can be widely modified. The seat according to the present invention may be applied to a passenger seat or a rear seat of a vehicle, or may be applied to a vehicle seat other than a vehicle such as an aircraft. The position of the opening may be shifted.
