以下に、図を用いて本発明の実施例を説明する。 In the present invention, a skin layer of a seat cushion and a seat back of a vehicle seat such as a passenger car is constituted by a skin member, a flexible intermediate layer member, and a back side member, and the intermediate member has a ventilation path and a skin member on the ventilation path. A hole that leads to the side is formed, and the wind sent from the blower through the duct for blowing is sent to the ventilation path of the intermediate member, and the occupant is exposed from the surface of the seat cushion and the seat back from the skin member side through the hole. It is designed to be discharged to the seated side.
Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１は、本発明の対象である車両用シート１００の外観を示す。車両用シート１００は、乗員(図示せず)が座るシートクッション１１０と、シートクッション１１０に座った乗員が背を凭れるシートバック１２０、乗員の頭部を支えるヘッドレスト１３０を備えている。   FIG. 1 shows the appearance of a vehicle seat 100 that is the subject of the present invention. The vehicle seat 100 includes a seat cushion 110 on which an occupant (not shown) sits, a seat back 120 on which the occupant sitting on the seat cushion 110 turns his back, and a headrest 130 that supports the head of the occupant.

図２は、車両用シート１００の断面を模式的に示したものである。１１１はシートクッション１１０のシートカバー、１１２はウレタンで形成されたシートクッション１１０のパッド部材である。また、１２１はシートバック１２０のシートカバー、１２２はウレタンで形成されたシートバック１２０のパッド部材である。図２では、ヘッドレスト１３０の表示およびフレーム部材の表示を省略している。   FIG. 2 schematically shows a cross section of the vehicle seat 100. Reference numeral 111 denotes a seat cover of the seat cushion 110, and 112 denotes a pad member of the seat cushion 110 made of urethane. Reference numeral 121 denotes a seat cover of the seat back 120, and 122 denotes a pad member of the seat back 120 formed of urethane. In FIG. 2, the display of the headrest 130 and the display of the frame member are omitted.

車両用シート１００は、シートクッション１１０の下部に送風機であるファン１４０と、送風用ダクト１４１を備えている。ファン１４０は、シートクッション１１０の下部で車内の空気を吸い込んで送風用ダクト１４１の側に排出する。ファン１４０から吸い込まれて送風用ダクト１４１の側に排出された空気(風)は、シートクッション１１０とシートバック１２０のシートカバー１１１および１２１の表面から、乗員が着座する側に送り出される。   The vehicle seat 100 includes a fan 140 that is a blower and a blower duct 141 under the seat cushion 110. The fan 140 sucks air in the vehicle at the lower part of the seat cushion 110 and discharges it to the air duct 141 side. Air (wind) sucked from the fan 140 and discharged to the air duct 141 side is sent out from the surface of the seat covers 111 and 121 of the seat cushion 110 and the seat back 120 to the side where the occupant is seated.

図３にシートカバー１１１および１２１の構成を示す。シートカバー１１１および１２１は、座面側表皮部材３１、中間層部材３２、パッド側部材３３で構成されている。   FIG. 3 shows the configuration of the seat covers 111 and 121. The seat covers 111 and 121 include a seat surface side skin member 31, an intermediate layer member 32, and a pad side member 33.

座面側表皮部材３１は通気性のある布、または多数の孔３１１を設けて通気性を持たせた皮などで形成されている。一方、パッド側部材３３は、不織布又は樹脂製のシートなどの通気性を持たない材料で形成されている。   The seat surface side skin member 31 is formed of a breathable cloth or a skin provided with a large number of holes 311 to provide a breathability. On the other hand, the pad side member 33 is formed of a non-breathable material such as a nonwoven fabric or a resin sheet.

中間層部材３２は、例えばウレタンなどの弾力性のある材料を素材とし、シートクッション１１０の前後方向、シートバック１２０の上下方向に沿って凹部３２１が複数形成されている。また、凹部３２１の上面３２２には、孔３２３が複数形成されている。孔３２３の位置を変えることにより、シートカバー１１１および１２１の表面から乗員が着座する側に空気を送り出す位置を変えることができる。   The intermediate layer member 32 is made of, for example, an elastic material such as urethane, and a plurality of concave portions 321 are formed along the front-rear direction of the seat cushion 110 and the vertical direction of the seat back 120. A plurality of holes 323 are formed in the upper surface 322 of the recess 321. By changing the position of the hole 323, the position at which air is sent from the surface of the seat covers 111 and 121 to the side where the occupant is seated can be changed.

図４にシートカバー１１１および１２１の断面を示す。図中の矢印は、送風用ダクト１４１を介してファン１４０から送られてきた空気の流れを示している。図で、右側の方向から送られてきた空気は、中間層部材３２に形成した凹部３２１と通気性を持たないパッド側部材３３とで形成される空間(溝空間)に沿って流れる。凹部３２１は中間層部材３２の端部３２４が残るように形成されているので、凹部３２１とパッド側部材３３とで形成される空間に沿って図の右側から送られてきた空気が左側に抜けてしまうことはない。   FIG. 4 shows a cross section of the seat covers 111 and 121. The arrows in the figure indicate the flow of air sent from the fan 140 via the air duct 141. In the drawing, the air sent from the right direction flows along a space (groove space) formed by the recess 321 formed in the intermediate layer member 32 and the pad side member 33 having no air permeability. Since the recess 321 is formed so that the end 324 of the intermediate layer member 32 remains, the air sent from the right side of the drawing along the space formed by the recess 321 and the pad side member 33 escapes to the left side. There is no end to it.

凹部３２１とパッド側部材３３とで形成される空間に沿って流れた空気は、中間層部材３２の凹部３２１の上面３２２に形成した多数の孔３２３から通気性のある座面側表皮部材３１を通って、座面側表皮部材３１から外部の乗員が着座する側に流れ出す。   The air that flows along the space formed by the recess 321 and the pad side member 33 passes through the air-permeable seat surface side skin member 31 through the numerous holes 323 formed in the upper surface 322 of the recess 321 of the intermediate layer member 32. It flows out from the seat surface side skin member 31 to the side where an external occupant is seated.

このように、ファン１４０から送り出された空気がシートクッション１１０およびシートバック１２０の表面を覆う座面側表皮部材３１から外部の乗員が着座する側に流れ出すことにより、シートクッション１１０及びシートバック１２０の通気性が良くなり、着座した乗員に対して快適な座り心地を提供することができる。   As described above, the air sent out from the fan 140 flows out from the seat surface side skin member 31 covering the surfaces of the seat cushion 110 and the seat back 120 to the side where the external occupant is seated, so that the seat cushion 110 and the seat back 120 are The air permeability is improved, and a comfortable sitting comfort can be provided to a seated passenger.

図２のＡ部、即ち、送風用ダクト１４１とシートクッション１１０側のシートカバー１１１及びシートバック１２０側のシートカバー１２１との接続部の構成の拡大図を、図５に示す。送風用ダクト１４１の先端部分付近は、シートクッション１１０側のシートカバー１１１とシートバック１２０側のシートカバー１２１とに挟まれている。   FIG. 5 shows an enlarged view of the configuration of the connection part between the portion A in FIG. 2, that is, the air duct 141, the seat cover 111 on the seat cushion 110 side, and the seat cover 121 on the seat back 120 side. The vicinity of the front end portion of the air duct 141 is sandwiched between the seat cover 111 on the seat cushion 110 side and the seat cover 121 on the seat back 120 side.

このような構成で、ファン１４０から送り出された空気は、矢印で示すように送風用ダクト１４１の先端部分から、送風用ダクト１４１の先端部分付近のシートクッション１１０側のシートカバー１１１とシートバック１２０側のシートカバー１２１とに挟まれた空間２１０に排出される。空間２１０に排出された空気は、シートカバー１１１及びシートカバー１２１の通気性のある座面側表皮部材３１から中間層部材３２に形成した多数の孔３２３を通って凹部３２１の側に流れる。   With such a configuration, the air sent out from the fan 140 flows from the front end portion of the air duct 141 to the seat cover 111 and the seat back 120 on the seat cushion 110 side near the front end portion of the air duct 141 as indicated by arrows. The sheet is discharged into a space 210 sandwiched between the side seat cover 121. The air discharged into the space 210 flows from the air-permeable seating surface side skin member 31 of the seat cover 111 and the seat cover 121 through the numerous holes 323 formed in the intermediate layer member 32 to the concave portion 321 side.

凹部３２１は中間層部材３２の端部３２４が残るように形成されているので、凹部３２１の側に流れた空気は、前述したように、凹部３２１と通気性を持たないパッド側部材３３とで形成される空間に沿って、図４で説明したようにシートクッション１１０側またはシートバック１２０側に流れて、中間層部材３２の凹部３２１の上面３２２に形成した多数の孔３２３から通気性のある座面側表皮部材３１を通って、座面側表皮部材３１から外部の乗員が着座する側に流れ出す。   Since the concave portion 321 is formed so that the end portion 324 of the intermediate layer member 32 remains, the air flowing to the concave portion 321 side is, as described above, between the concave portion 321 and the pad side member 33 having no air permeability. As described with reference to FIG. 4, along the space to be formed, it flows toward the seat cushion 110 or the seat back 120, and is air permeable from a large number of holes 323 formed in the upper surface 322 of the recess 321 of the intermediate layer member 32. It flows out from the seat surface side skin member 31 to the side where an external occupant is seated through the seat surface side skin member 31.

図６に図５のＢ−Ｂ断面図、即ち送風用ダクト１４１とシートクッション１１０側のシートカバー１１１およびシートバック１２０側のシートカバー１２１との接合部の断面を示す。シートクッション１１０側のシートカバー１１１とシートバック１２０側のシートカバー１２１とは、送風用ダクト１４１を挟むようにして両側の１５１および１５２の位置で縫合されている。これにより、送風用ダクト１４１から空間２１０に排出され空気のうち送風用ダクト１４１とシートカバー１１１およびシートカバー１２１との隙間から外部の漏れ出る空気の量を少なくして、中間層部材３２の凹部３２１の側に流れる空気の量を多くすることができる。   FIG. 6 is a cross-sectional view taken along the line B-B of FIG. 5, that is, a cross section of a joint portion between the air duct 141, the seat cover 111 on the seat cushion 110 side, and the seat cover 121 on the seat back 120 side. The seat cover 111 on the seat cushion 110 side and the seat cover 121 on the seat back 120 side are stitched at positions 151 and 152 on both sides so as to sandwich the air duct 141. Accordingly, the amount of air leaking outside from the gap between the air duct 141 and the seat cover 111 and the seat cover 121 out of the air discharged from the air duct 141 into the space 210 is reduced, and the concave portion of the intermediate layer member 32 is formed. The amount of air flowing to the 321 side can be increased.

図７に、送風用ダクト１４１とシートクッション１１０側のシートカバー１１１及びシートバック１２０側のシートカバー１２１との接続部の構成の変形例を示す。   FIG. 7 shows a modification of the configuration of the connecting portion between the air duct 141 and the seat cover 111 on the seat cushion 110 side and the seat cover 121 on the seat back 120 side.

図７に示した例においては、シートカバー１１１とシートカバー１２１との座面側表皮部材３１と中間層部材３２との長さを通気性を持たないパッド側部材３３よりも短くして、送風用ダクト１４１をパッド側部材３３で挟み込み、送風用ダクト１４１の両側のパッド側部材３３を図６の場合と同様に縫合する構造とした。この場合、中間層部材３２の凹部３２１は、中間層部材３２を突き抜けるように形成されており、送風用ダクト１４１の先端部分とシートカバー１１１とシートカバー１２１と囲まれる空間２２０に、中間層部材３２に形成された凹部３２１の端面が開口している状態になる。   In the example shown in FIG. 7, the lengths of the seat surface side skin member 31 and the intermediate layer member 32 of the seat cover 111 and the seat cover 121 are made shorter than the non-breathable pad side member 33, The duct 141 is sandwiched between the pad-side members 33, and the pad-side members 33 on both sides of the blower duct 141 are sewn in the same manner as in FIG. In this case, the concave portion 321 of the intermediate layer member 32 is formed so as to penetrate the intermediate layer member 32, and the intermediate layer member is formed in a space 220 surrounded by the tip portion of the air duct 141, the seat cover 111, and the seat cover 121. The end surface of the recess 321 formed in 32 is in an open state.

このような構成で、ファン１４０から送り出された空気は、送風用ダクト１４１の先端部分から、空間２２０に排出される。空間２２０に排出された空気は、矢印で示したように中間層部材３２の端面の凹部３２１の開口から凹部３２１と通気性を持たないパッド側部材３３とで形成される空間に沿ってシートクッション１１０側またはシートバック１２０側に流れて、中間層部材３２の凹部３２１の上面３２２に形成した多数の孔３２３から通気性のある座面側表皮部材３１を通って、座面側表皮部材３１から外部の乗員が着座する側に流れ出す。   With such a configuration, the air sent out from the fan 140 is discharged into the space 220 from the tip portion of the air duct 141. The air discharged into the space 220 is seat cushioned along the space formed by the recess 321 and the non-breathable pad side member 33 from the opening of the recess 321 on the end surface of the intermediate layer member 32 as indicated by the arrow. From the seat surface side skin member 31 through the air-permeable seat surface side skin member 31 through a large number of holes 323 formed on the upper surface 322 of the recess 321 of the intermediate layer member 32. It flows out to the side where the external passenger is seated.

中間層部材３２の凹部３２１の上面３２２に形成する孔３２３の大きさの分布や数、孔の間隔(配置)等を変えることで、空気の流れだす量及びその分布を変えることができる。例えばシートクッション１１０側に対してシートバック１２０側の中間層部材３２の孔３２３の大きさを小さくした数を少なくすることにより、シートクッション１１０側から流れ出す空気の量に対してシートバック１２０側から流れ出す空気の量を少なく設定することができる。   By changing the size distribution and number of the holes 323 formed in the upper surface 322 of the concave portion 321 of the intermediate layer member 32, the interval (arrangement) of the holes, and the like, the amount of air flowing out and the distribution thereof can be changed. For example, by reducing the number of holes 323 of the intermediate layer member 32 on the seat back 120 side smaller than the seat cushion 110 side, the amount of air flowing out from the seat cushion 110 side is reduced from the seat back 120 side. The amount of air flowing out can be set small.

また、同じシートクッション１１０又はシートバック１２０の面内でも、中間層部材３２の孔３２３の大きさの分布や孔３２３の間隔(配置)等を調整することにより、周辺部に対して中央部から流れ出す空気の量を多くなるように設定したり、その逆に少なくなるように設定することもできる。   Further, even within the surface of the same seat cushion 110 or seat back 120, the distribution of the size of the holes 323 of the intermediate layer member 32, the interval (arrangement) of the holes 323, and the like can be adjusted from the central portion to the peripheral portion. The amount of air that flows out can be set to be large, or vice versa.

本実施例によれば、ファン１４０から送り出されて送風用ダクト１４１からシートカバー１１１とシートカバー１２１の側に送り出された空気を、シートカバー１１１とシートカバー１２１の中間層部材３２に形成した凹部３２１と通気性を持たないＰＡＤ側部材３３とで形成される空間に沿って流れるように構成したので、中間層部材３２を形成時に一緒に凹部３２１を形成することができ、比較的低いコストで空気の流路を形成することができるようになった。   According to the present embodiment, the recessed portion formed in the intermediate layer member 32 of the seat cover 111 and the seat cover 121 by the air sent from the fan 140 and sent from the air duct 141 to the seat cover 111 and the seat cover 121 side. 321 and the PAD side member 33 that does not have air permeability are configured to flow along the space formed therein, so that the concave portion 321 can be formed together with the intermediate layer member 32 at the time of formation, at a relatively low cost. An air flow path can be formed.

以上、本発明者によってなされた発明を実施例に基づき具体的に説明したが、本発明は前記実施例に限定されるものではなく、その要旨を逸脱しない範囲で種々変更可能であることは言うまでもない。   As mentioned above, although the invention made by the present inventor has been specifically described based on the embodiments, it is needless to say that the present invention is not limited to the above embodiments and can be variously modified without departing from the gist thereof. Yes.
