Description

本発明は、空調機能を有するシート、とくに、空調機能の自由度を大きくできるシートの構造に関する。   The present invention relates to a sheet having an air conditioning function, and more particularly to a structure of a sheet that can increase the degree of freedom of the air conditioning function.

従来知られている車両用空調シートは、図4に例示されているように、シートクッション1のパット材2内、及び、シートバック3のパット材4内に、それぞれシートクッション1の座面全体に複数の吹き出し口5が分散配置された冷風路6、及び、シートバック3の背もたれ面全体に複数の吹き出し口7が分散配置された冷風路8を形成させ、冷風源9からそれぞれ導風路10、11を経て冷風路6、8へ送給された冷風が、それぞれ吹き出し口5、7から通気性のシート表皮12、13を通って、着座者へ送り出されるようになっている。   As shown in FIG. 4, the conventionally known vehicle air-conditioning seat has the entire seating surface of the seat cushion 1 in the pad material 2 of the seat cushion 1 and in the pad material 4 of the seat back 3. A cooling air passage 6 in which a plurality of air outlets 5 are distributed and a cooling air passage 8 in which a plurality of air outlets 7 are distributed over the entire backrest surface of the seat back 3 are formed. The cold air fed to the cold air passages 6 and 8 through 10 and 11 is sent out to the seated person through the breathable sheet skins 12 and 13 from the blowout ports 5 and 7, respectively.

しかしながら、この場合には、空調機能を持たないシートのパット材とは全く別構造のパット材2、4を特別に準備する必要があって、パット材の種類が増加することとなるため、結果的に車両用シートの製造コストを全体的に押し上げる要因となっていた。   However, in this case, it is necessary to specially prepare the pad materials 2 and 4 having a completely different structure from the pad material of the sheet that does not have the air conditioning function. In particular, the manufacturing cost of the vehicle seat has been increased as a whole.

なお、空調機能を有するシートとして、下記特許文献1及び特許文献2に示された技術も従来から知られている。   In addition, as a sheet | seat which has an air-conditioning function, the technique shown by the following patent document 1 and the patent document 2 is also known conventionally.

特開平10−215975号公報Japanese Patent Laid-Open No. 10-215975 特開平11−59163号公報Japanese Patent Laid-Open No. 11-59163

特許文献1の場合には、シートクッションにおける送気路、及び、シートバックにおける送気路の広がり形状によって、シートクッション及びシートバックでの送風分布がほぼ決められてしまうため、送風分布の自由度が比較的小さくなると同時に、パット材中に特定の大きな送気路を設置する必要があるため、製造コストが嵩むという問題があり、また、特許文献2の場合は上記従来技術と同等の不具合を避けることができないものである。   In the case of Patent Document 1, the air distribution in the seat cushion and the seat back is almost determined by the air supply path in the seat cushion and the shape of the air supply path in the seat back. Is relatively small, and at the same time, it is necessary to install a specific large air supply path in the pad material. Therefore, there is a problem that the manufacturing cost increases, and in the case of Patent Document 2, there is a problem equivalent to the above prior art. It cannot be avoided.

本発明は、空調機能の自由度を容易に大きくできるシートを提供しようとするものである。   The present invention is intended to provide a seat that can easily increase the degree of freedom of the air conditioning function.

このため、本発明にかかる空調シートは、シートクッションまたはシートバックがそれぞれ弾性の大きいシートクッション基材またはシートバッククッション基材と、上記シートクッション基材または上記シートバッククッション基材の着座者側に配置された空調クッションと、通気性をそなえて上記空調クッションを覆う表皮とを有し、上記空調クッションは通気性のあるクッション材が実質的に通気性のない生地材で包まれ、上記生地材に空調空気の送入口と着座者側に開いた複数の吹き出し口とが形成されている。   For this reason, the air-conditioning seat according to the present invention is provided on the seat cushion base or the seat back cushion base where the seat cushion or the seat back has great elasticity, and on the seated person side of the seat cushion base or the seat back cushion base. An air-conditioning cushion arranged and a skin covering the air-conditioning cushion with air permeability, wherein the air-conditioning cushion is wrapped with a non-breathable fabric material, and the fabric material In addition, an inlet port for conditioned air and a plurality of outlets opened on the seated side are formed.

すなわち、弾性の大きいシートクッション基材またはシートバッククッション基材の着座者側(着座面側または背もたれ面側)に配置された空調クッションは、目の粗い可撓性の生地であってその面方向及びその面と交わる方向のいずれにも通気性が大きい、いわゆる、通気性のあるクッション材を実質的に通気性のない生地材が包んでいるので、生地材に形成された送入口から通気性のあるクッション材へ空調空気が送給されると、その空調空気は通気性のあるクッション材内を適宜その面方向等へ流れ、生地材において着座者側に開いた複数の吹き出し口から流出し、通気性をそなえた表皮を通って着座者側へ吹き出される結果、着座者に対する空調作用を果たすことができる一方、生地材における吹き出し口の分布、個数、形状、大きさ等を調整することにより、上記空調機能を容易に制御できるため、空調機能の自由度を簡単に高めることが可能となる。   That is, the air-conditioning cushion arranged on the seat occupant side (the seating surface side or the back surface side) of the seat cushion base material or the seat back cushion base material having high elasticity is a flexible fabric with a coarse mesh and its surface direction. In addition, air permeability is great in both the direction intersecting with the surface, so-called air-permeable cushion material is wrapped in a substantially non-breathable fabric material, so the air permeability from the inlet formed in the fabric material When air-conditioned air is supplied to a cushioning material, the air-conditioned air flows in the air-permeable cushioning material as appropriate in the direction of the surface, etc., and flows out from a plurality of outlets opened on the seated person side in the fabric material. As a result of being blown out to the seated person through the skin with air permeability, the air conditioning function for the seated person can be achieved, while the distribution, number, shape and size of the outlets in the fabric material By adjusting the like, it is possible to easily control the air conditioning function, it is possible to increase easily the freedom of the air conditioning function.

以下、本発明の実施例について説明する。
図1において、車両用空調シート20は、シートクッション21が弾性の大きいシートクッション基材(パット材)22と、シートクッション基材22の着座面側に配置された空調クッション23と、通気性をそなえて空調クッション23を覆う表皮24とを有していると共に、シートバック25が弾性の大きいシートバッククッション基材(パット材)26と、シートバッククッション基材26の背もたれ面側に配置された空調クッション27と、通気性をそなえて空調クッション27を覆う表皮28とを有している。
Examples of the present invention will be described below.
In FIG. 1, a vehicle air-conditioning seat 20 has a breathable property with a seat cushion base material (pad material) 22 having a large seat cushion 21 and an air-conditioning cushion 23 disposed on the seating surface side of the seat cushion base material 22. In addition, it has a skin 24 that covers the air conditioning cushion 23, and the seat back 25 is disposed on the backrest surface side of the seat back cushion base material (pad material) 26 having high elasticity and the seat back cushion base material 26. The air conditioning cushion 27 and the skin 28 that covers the air conditioning cushion 27 with air permeability are provided.

空調クッション23、27は、図2に示されているように、それぞれ実質的に通気性のない生地材30により、通気性のあるクッション材、例えば、ダブルラッセル組織をセンターカットしたダブルラッセル生地31が包まれているものであって、図3に空調クッション23の場合が例示されているように、それぞれ生地材30の着座面側及び背もたれ面側に、それぞれ着座者が接触する表皮24、28の部位に接して複数の吹き出し口32が開かれ、吹き出し口32は適宜の分布状態で、適宜の個数、形状、大きさに形成されていると共に、生地材30の着座者側と反対側における中央部付近にそれぞれ単一の送入口33が形成され、上記各送入口33は、それぞれシートクッション基材22内及びシートバッククッション基材26内に設けられた空気通路34によって冷風源35と接続されている。   As shown in FIG. 2, the air-conditioning cushions 23 and 27 are made of a breathable cushion material, for example, a double raschel fabric 31 obtained by center-cutting a double raschel structure with a substantially non-breathable fabric material 30. As shown in the case of the air-conditioning cushion 23 in FIG. 3, the skins 24 and 28 where the seated person comes into contact with the seating surface side and the backrest surface side of the fabric material 30, respectively. A plurality of air outlets 32 are opened in contact with each other, and the air outlets 32 are formed in an appropriate number, shape and size in an appropriate distribution state, and on the opposite side of the fabric material 30 from the seated person side. A single inlet 33 is formed near the center, and each inlet 33 is provided in the seat cushion base material 22 and the seat back cushion base material 26, respectively. And it is connected to the cold air source 35 by the air passage 34 which is.

従って、冷風源35から空気通路34を通って空調クッション23、27の各送入口33により各ダブルラッセル生地31へ送給された冷風は、各ダブルラッセル生地31内を適宜その面方向等のあらゆる方向へ拡散して流れ、それぞれ生地材30の吹き出し口32から流出して、それぞれ通気性をそなえた表皮24、28の着座者が接触する部位を通って着座者側へ吹き出されることとなって、着座者の背中及び膝下等に対する空調機能を果たすことができるが、このとき、吹き出し口32の分布、個数、形状、大きさ等を適宜選定することにより、表皮24、28から吹き出される個所や風量等を調整でき、しかも、吹き出し口32の分布、個数、形状、大きさ等の設定はきわめて自由、かつ、容易であるため、上記空調機能を容易に制御できることとなって、空調機能の自由度を簡単に高めることが可能となる特色がある。   Accordingly, the cold air fed from the cold air source 35 through the air passage 34 to the double raschel fabrics 31 through the inlets 33 of the air conditioning cushions 23 and 27 is appropriately transmitted through the double raschel fabrics 31 in any direction such as the surface direction. It flows in a direction, flows out from the outlet 32 of the dough material 30, and is blown out to the seated person side through the part where the seated person of the skins 24 and 28 having air permeability contact each other. Thus, the air conditioning function for the seated person's back and under the knee can be achieved. At this time, the air outlet 32 is blown out from the skins 24 and 28 by appropriately selecting the distribution, number, shape, size, and the like of the outlet 32. The location, air volume, etc. can be adjusted, and the distribution, number, shape, size, etc. of the outlets 32 can be set very freely and easily. Becomes able to, there is a feature that is possible to increase easily the freedom of the air conditioning function.

また、空調クッション23、27はそれぞれ表皮24、28に覆われているので、シート20の外観が従来のシートと変わらず、しかも、着座者によって損耗することがないためその耐久性を確実に向上させることができると共に、空調クッション23、27の吹き出し口32から流出した冷風はそれぞれ表皮24、28を通って着座者側へ吹き出されるため、着座者に対し直接的に吹きつけることがなくて、穏やかな空調作用を行わせることができる。   In addition, since the air conditioning cushions 23 and 27 are covered with the skins 24 and 28, respectively, the appearance of the seat 20 is the same as that of the conventional seat and is not worn out by the seated person, so that the durability is surely improved. In addition, the cool air that has flowed out from the air outlet 32 of the air conditioning cushions 23 and 27 is blown out to the seated person through the skins 24 and 28, respectively, so that it is not blown directly to the seated person. It can be made to have a gentle air conditioning.

さらに、空調シート20では、従来のように、シートクッション21のシートクッション基材22内、及び、シートバック25のシートバッククッション基材26内に、冷風の吹き出し口や冷風路を形成させる必要が全くないので、単に、空調クッション23、27を取り除くことにより、空調機能を持たないシートとすることができる、すなわち、比較的大型のシートクッション基材22及びシートバッククッション基材26を、空調シート20と空調機能を必要としないシートとに容易に共用化できることとなるので、シート形状やシートレイアウトが異なる車両用シートの製造コストを全体的に低減させることができる実用的長所がある。   Furthermore, in the air-conditioning seat 20, it is necessary to form a cold air outlet and a cold air passage in the seat cushion base material 22 of the seat cushion 21 and in the seat back cushion base material 26 of the seat back 25 as in the past. Since there are no air conditioning cushions 23 and 27, the seat without air conditioning function can be obtained by simply removing the air conditioning cushions 23 and 27. That is, the relatively large seat cushion base material 22 and the seat back cushion base material 26 can be used as the air conditioning seat. 20 and a seat that does not require an air-conditioning function can be easily shared. Therefore, there is a practical advantage that the manufacturing cost of a vehicle seat having a different seat shape and seat layout can be reduced as a whole.

なお、空調シート20から空調クッション23、27を取り除いた場合、仮に、シートクッション基材22と表皮24との間や、シートバッククッション基材26と表皮28との間に少々の隙間が生じやすいとしても、表皮24、28の厚みによってそれぞれ容易に吸収させることができるので、あるいは、上記吸収が完全でないときには、それぞれ空調クッション23、27とほぼ等しい厚み等の板状クッション材を空調クッション23、27と置き換えるようにすれば、上記共用化を容易に達成することが可能となるものである。   When the air conditioning cushions 23 and 27 are removed from the air conditioning seat 20, a slight gap is likely to be generated between the seat cushion base material 22 and the skin 24 or between the seat back cushion base material 26 and the skin 28. However, since it can be easily absorbed by the thickness of the skins 24 and 28, or when the absorption is not complete, a plate-like cushion material having a thickness substantially equal to the air conditioning cushions 23 and 27, respectively, is used. If it is replaced with 27, the above-mentioned sharing can be easily achieved.

また、上記実施例では、生地材30の着座者側と反対側における中央部付近に送入口33が形成されているが、ダブルラッセル生地31の面方向における通気性が大であるため、吹き出し口32の分布、個数、形状、大きさ等を考慮して送入口33の位置を適宜変更し、あるいは、必要に応じて空調クッション23、27の周縁部で生地材30に、上記送入口33に代わる送入口を設けるようにしても、上記実施例と同等の作用効果を発揮することができ、また、上記各実施例における冷風を温風あるいは常温風に代えることができ、さらに、通気性のあるクッション材として、ダブルラッセル生地の外に、ダブルラッセル編みが施されたままの生地や、不織布や、ファイバーシート等の通気性材料を使用することもできるのはいうまでもない。   Moreover, in the said Example, although the inlet 33 is formed in the center part vicinity on the opposite side to the seated person side of the fabric material 30, since the air permeability in the surface direction of the double Russell fabric 31 is large, a blower outlet The position of the inlet 33 is appropriately changed in consideration of the distribution, number, shape, size, etc. of 32, or, if necessary, the fabric material 30 at the periphery of the air conditioning cushions 23, 27 and the inlet 33. Even if an alternative inlet is provided, the same effects as the above-described embodiments can be exhibited, and the cold air in each of the above-described embodiments can be replaced with warm air or room temperature air. Needless to say, as a cushioning material, in addition to the double raschel fabric, a fabric that has been subjected to double raschel knitting, a non-woven fabric, or a breathable material such as a fiber sheet can be used. .
