Description

【0001】
【発明の属する技術分野】
本発明は、車両用シートに内蔵される車両用シート空調装置に関するものである。
【0002】
【従来の技術】
従来の車両用シート空調装置は種々提案されており、空調風を送風する送風ユニットをシートのクッション部材中または外部に配置し、送風ユニットの流入ダクト部をクッション部材の導風通路に挿入するものが提案されている(例えば、特許文献1参照)。
【0003】
【特許文献1】
特開2000−152849号公報
【0004】
【発明が解決しようとする課題】
ところで、送風ユニットの流入ダクト部はクッション部材の導風通路に直接挿入されているので、送風ユニットが回転駆動されると、送風ユニットの振動がクッション部材に伝達されやすい。このため、座り心地を損ねるという不具合が発生しやすい。
【0005】
本発明は上記点に鑑みて、車両用シート内へ送風ユニットが搭載された場合に、送風ユニットの流入ダクト部の接続に起因する座り心地の悪化を抑制することを目的とする。
【0006】
【課題を解決するための手段】
上記目的を達成するため、請求項1に記載の発明では、乗員のクッション作用を行い、内部に空気を導風する導風通路(25a)が設けられたクッション部材(25)と、クッション部材(25)の外部に配置され、送風を行う送風ユニット(13)とを備え、送風ユニット(13)の空気出口側部位に、導風通路(25a)へ送風空気を流入させる流入ダクト部(30)を設け、流入ダクト部(30)が導風通路(25a)に挿入された状態で、流入ダクト部(30)と導風通路(25a)とが接続される車両用シート空調装置であって、流入ダクト部(30)の外周面(30c)と導風通路(25a)の内周面(25b)との間に隙間(25c)を設け、クッション部材(25)と流入ダクト部(30)の間に、送風ユニット(13)の振動をクッション部材(25)に伝達することを抑制する緩衝部材(32)を設け、この緩衝部材(32)を介してのみ、流入ダクト部(30)とクッション部材(25)とが接する構成としたことを特徴とする。
【0007】
これによれば、緩衝部材を設けているので、送風ユニット(13)の振動をクッション部材(25)に伝わりにくくすることができる。したがって、乗員のクッション部材(25)への座り心地を良好に維持できる。また、クッション部材(25)の振動が送風ユニット(13)に伝わりにくくできるので、両者(13、25)の共振の発生も低減できる。
【0009】
また、これによれば、流入ダクト部(30)と導風通路(25a)との間に隙間(25c)設けているので、送風ユニット(13)が振動しても流入ダクト部(30)の外周面(30c)が導風通路(25a)に接触しにくくなり、隙間(25c)がない場合に比べて送風ユニット(13)の振動をクッション部材(25)に伝わりにくくすることができる。
具体的には、請求項2に記載の発明のように、流入ダクト部(30)の先端部(30a)から所定寸法(L1)の位置に、流入ダクト部(30)の径方向に拡がる台座(30b)を設け、クッション部材(25)の送風ユニット(13)側の端面(25d)と、台座(30b)のクッション部材(25)側の端面(30d)との間に緩衝部材(32)を配置する構成とすることができる。
また、請求項3に記載の発明では、導風通路(25a)の内周面(25b)と流入ダクト部(30)の外周面(30c)との間に緩衝部材(32)を設け、この緩衝部材(32)を介してのみ、流入ダクト部(30)とクッション部材(25)とが接する構成としたことを特徴とする。
これにより、流入ダクト部がクッション部材の導風通路に直接挿入されている場合と比較して、送風ユニット(13)の振動をクッション部材(25)に伝わりにくくすることができる。したがって、乗員のクッション部材(25)への座り心地を良好に維持できる。また、クッション部材(25)の振動が送風ユニット(13)に伝わりにくくできるので、両者(13、25)の共振の発生も低減できる。
【0010】
請求項に記載の発明では、衝部材(32)は、通気性が低い部材で構成されていることを特徴とする。
【0011】
これにより、緩衝部材(32)が低通気の性質を有するので、流入ダクト部(30)と導風通路(25a)の間から送風空気が抜けにくくなる。
【0014】
請求項に記載の発明のように、衝部材(32)をクッション部材(25)および流入ダクト部(30)の少なくとも一方に接着固定すれば、接着面を気密にできるとともに、組立を容易にすることができる。
【0021】
なお、上記各手段の括弧内の符号は、後述する実施形態に記載の具体的手段との対応関係を示すものである。
【0022】
【発明の実施の形態】
(第1実施形態)
第1実施形態は、本発明の車両用シート空調装置をシートクッション部11に適用したものである。
図1は第1実施形態による車両用シート10の概要を示すもので、この車両用シート10は具体的には運転席あるいは助手席のシートとして使用されるものである。
【0023】
車両用シート10には、乗員の尻部を支持するシートクッション部11と、乗員の背中部を支持するシート背もたれ部(シートバック部)12が備えられている。シートクッション部11の内部およびシート背もたれ部12の内部にはそれぞれ、第1送風ユニット13、第2送風ユニット14が内蔵されている。
【0024】
第1送風ユニット13はシートクッション部11の下方部に空気吸入口29を配置し、この空気吸入口から車室内空気を吸入し、そして、この吸入空気をシートクッション部11の内部の空気通路15を通してシートクッション部11の表皮部材16に送風し、この表皮部材16に開口している多数の小穴からなる吹出開口部17から空気(空調風)を矢印aのように乗員の身体に向けて吹き出すようになっている。
【0025】
また、第2送風ユニット14も同様の空気送風機能を果たすものであり、シート背もたれ部12のうち下部側の部位に図示しない空気吸入口を配置し、この空気吸入口から車室内空気を吸入し、そして、シート背もたれ部12の内部の空気通路18、シート背もたれ部12の表皮部材19に設けた多数の小穴からなる吹出開口部20から空気(空調風)を矢印bのように乗員の身体に向けて吹き出すようになっている。
【0026】
なお、室内空調ユニット部21は車室内前部の計器盤(インストルメントパネル、図示せず)内側等に設置され、この室内空調ユニット部21から吹き出す空調風により車室内が空調される。従って、第1、第2送風ユニット13、14は車室内の空調された空気を送風することができる。
【0027】
また、シートクッション部11およびシート背もたれ部12において、各表皮部材16、19の裏側にそれぞれ電気ヒータ22、23が配置してある。この電気ヒータ22、23はワイヤー状の電気抵抗体から構成され、シートクッション部11およびシート背もたれ部12の乗員当たり面の広い範囲にわたって蛇行状に配置されている。
【0028】
シートクッション部11は、図2に示すように、表皮部材16の裏側(内側)に、置きパット部24とクッション部材25とを積層配置している。このうち、クッション部材25は、カバーパット部および置きパット部24に比較して十分大きな厚み寸法(例えば、40mm程度)が設定され、シートのクッション作用を主に発揮する部分である。なお、表皮部材16と置きパット部24の間には図示しないカバーパッド部が設けられている。
【0029】
また、クッション部材25の表皮部材16側には空気通路15を構成し、吹出開口部17に空気を配風する配風溝26が設けられている。なお、配風溝26の代わりに、例えば網状体からなる通気性部材を用いてもよい。
【0030】
また、第1送風ユニット13の送風ケーシング27は、図1に示すように、渦巻状のスクロールケーシングを構成するものであって、その内部には遠心式送風ファン28が回転可能に配置されている。
【0031】
この遠心式送風ファン28を図示しない駆動用モータにより回転駆動すると、車室内床面近傍の空気が矢印cのように空気吸入口29を通過して送風ケーシング27内に吸入される。この吸入空気は、送風ケーシング27内を径外方側へ送風され、図2に示すように、空気吹出部に位置する流入ダクト30を通過し、貫通穴25aに流れるようになっている。
【0032】
この第1送風ユニット13はクッション部材25の直ぐ下方部に配置したワイヤー状のシートばね31により吊り下げ状態にて支持されている。ここで、第1送風ユニット13は、ワイヤ状のシートばね31の下方側、すなわち、シートばね31のうち、クッション部材25と反対側部位に位置した状態にて吊り下げ固定される。
【0033】
次に、本発明の要部であるクッション部材25の貫通穴25aと流入ダクト30の接続構成を図2および図3により説明すると、クッション部材25にはその厚さ方向(車両上下方向)に貫通する貫通穴25aが開けてある。この貫通穴25aは本発明の導風通路を構成するものであって、クッション部材25の車両左右方向の中央部付近で、かつ、車両前後方向に対しては前方寄りの部位に位置している。
【0034】
ところで、図3に示すように、貫通穴25aに接続される流入ダクト30のうち、流入ダクト30の先端部30aから流入ダクト30の軸方向に沿って所定寸法L1の位置には、径方向に円板状に形成された台座30bが設けられている。そして、先端部30aから台座30bまでの外周面30cは貫通穴25aの内周面25bに対して隙間25cを有するように形成されている。
【0035】
また、クッション部材25の第1送風ユニット13側の端面25dには緩衝部材32が貫通穴25aを閉塞するように配置されている。緩衝部材32は所定の厚みと内周面32aを有し、外周面が貫通穴25aより大きく構成された略円筒形状をしている。内周面32aは流入ダクト30の先端部外周面30cと略同一に形成されている。
【0036】
なお、緩衝部材32は第1送風ユニット13の送風空気に対して低通気の性質を有している。上記低通気とは、第1送風ユニット13によって送風された送風空気の一部が緩衝部材32の内部を通過しても、第1送風ユニット13の送風性能に影響を与えない程度のものとし、第1送風ユニット13の送風空気を通気しないものも含むものとする。
【0037】
クッション部材25の貫通穴25aと流入ダクト30の組立は、緩衝部材32の内周面32aに流入ダクト部30の外周面30cを挿入し、クッション部材25と台座30bの間に挟み込むようにして行われる。したがって、流入ダクト30の台座30bは緩衝部材32を保持する機能を果たしている。
【0038】
緩衝部材32の材質は、具体的には、エーテル系ウレタンフォームまたはエステル系ウレタンフォームであって、送風ケーシング27の振動を抑制する性質と、遠心式送風ファン28による送風空気が不通気となる性質を兼ね備えている。
【0039】
なお、緩衝部材32は図示しない接着剤によってクッション部材25との接触面を気密に接着してもよい。また、緩衝部材32は図示しない接着剤によって台座30bとの接触面を気密に接着してもよい。
【0040】
次に、上述した第1実施形態による作用効果を説明する。
【0041】
(1)第1送風ユニット13はクッション部材25の直ぐ下方部に配置したワイヤー状のシートばね31により吊り下げ状態にて支持されている。この状態にて流入ダクト部30と貫通穴25aの間に、第1送風ユニット13の振動がクッション部材25に伝達することを抑制する緩衝部材32が設けられているので、第1送風ユニット13の振動がクッション部材25に伝わりにくい。したがって、乗員のクッション部材25への座り心地を良好に維持できる。また、クッション部材25の振動が第1送風ユニット13に伝わりにくくなるので、両者13、25の共振の発生も低減できる。
【0042】
(2)流入ダクト部30の外周面30cと、貫通穴25aの内周面25bとの間に隙間25cを設けているので、送風ユニット13が振動しても流入ダクト部30の外周面30cが導風通路25aに接触しにくくなり、隙間25cがない場合に比べて送風ユニット13の振動をクッション部材25に伝わりにくくすることができる。
【0043】
(3)緩衝部材32が低通気の性質を有するので、流入ダクト部30と貫通穴25aの間から送風空気が抜けにくくなる。
【0044】
(4)緩衝部材32をクッション部材25および流入ダクト部30の少なくとも一方に接着固定すれば、接着面を気密にできるとともに、組立を容易にすることができる。
【0045】
(第2実施形態)
第1実施形態では、緩衝部材32をクッション部材25の第1送風ユニット13側の端面25dに配置したが、第2実施形態では、図4に示すように、円筒状の緩衝部材32を貫通穴25aの内周面25bに配置するようにしてもよい。具体的には、緩衝部材32の外周面が貫通穴25aの内径部に、緩衝部材32の内径部が流入ダクト部30の外周面30bに、それぞれ圧入されるように構成されてもよい。
【0046】
なお、緩衝部材32は図示しない接着剤によって貫通穴25aとの接触面を気密に接着してもよい。また、緩衝部材32は図示しない接着剤によって流入ダクト部30の外周面30cとの接触面を気密に接着してもよい。
【0047】
(第3実施形態)
第1、第2実施形態では、緩衝部材32を用いて第1送風ユニット13の振動がクッション部材25に伝わりにくいようにしたが、第3実施形態では、図5に示すように、緩衝部材32を用いずに、貫通穴25aの径内方向に突起した円環状の突起部25eを設けた構造とした。
【0048】
この突起部25eは、クッション部材25と一体に形成され、所定の厚さを有し、中心部に穴部25fが設けられている。この突起部25eの穴部25fに直接、流入ダクト30の外周面30cを挿入している。
【0049】
なお、上記円環状とは、穴部25fが円形だけではなく、楕円、長円、矩形のものを含めるものとする。なお、突起部25eは、図6に示すように、貫通穴25aのうち、クッション部材25の第1送風ユニット13側の端面25dから所定の深さL2の位置に形成されてもよい。
【0050】
第3実施形態によれば、円環状の突起部25eがクッション部材25と一体に設けられるので、送風ユニット13の振動をクッション部材25に伝わりにくくするのに、別部品として構成する必要がなく簡単な構造で実現できる。
【0051】
(他の実施形態)
第1〜第3実施形態では、本発明の車両用シート空調装置をシートクッション部11に適用したが、シート背もたれ部12に適用してもよい。
【0052】
また、第3実施形態では、突起部25eは1つのみであったが、貫通穴25aの内周面25bのうち、軸方向に複数設けてもよい。これによれば、第3実施形態より確実に送風空気の抜け防止をすることができる。
【0053】
また、第1〜第3実施形態では、シートクッション部11およびシート背もたれ部12にそれぞれ送風ユニット13、14を設けた車両用シート10に適用したが、図7に示すように、シートクッション部11にのみ送風ユニット13を設け、シートクッション部11およびシート背もたれ部12に送風するようにしたものに適用してもよい。
【0054】
また、第1〜第3実施形態では、第1送風ユニット13が車室内空気を吸入して、シート内部の空気通路15に送風しているが、図8に示すように、シートクッション部11にのみ送風ユニット13を設け、送風ユニット13の吸入口部29を適宜の連結ダクト33を介して室内空調ユニット21の空調風取り出し口に接続し、そして、室内空調ユニット21内にて温度調整された空調風(冷風、温風)を第1送風ユニット13内に吸収して、シート内部の空気通路15、18に送風するようにしてもよい。なお、室内空調ユニット21および第1送風ユニット13は制御盤34によって制御される。
【0055】
また、第1〜第3実施形態では、第1送風ユニット13が回転駆動された際に、送風空気が空気通路15を通って表皮部材16側に吹き出される車両用シート10に適用したが、表皮部材16側から空気を吸い込むようにした車両用シート10に適用してもよい。
【0056】
更に、第1送風ユニット13はワイヤ状のシートばね31により保持されていたが、クッション部材25の下方に剛体部品を設け、この剛体部品に第1送風ユニット13が保持されていてもよい。
