【発明が解決しようとする課題】
ところで上記従来の乗員拘束装置は、2個のインフレータを必要とするために部品点数が増加する問題があり、またルーフサイドレールの前後方向中央部にインフレータを配置しているので、もともとヘッドクリアランスが小さい乗員の頭部とルーフサイドレールとの距離が更に小さくなって居住性が低下する問題がある。
【0005】
本発明は前述の事情に鑑みてなされたもので、乗員拘束装置の部品点数を減少させるとともに、乗員とルーフサイドレールとの間のヘッドクリアランスを増加させて居住性を改善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に、請求項1に記載された発明によれば、折り畳んだエアバッグをルーフの左右両側部に沿って配置し、車両の衝突時にインフレータが発生するガスでエアバッグを膨張させて車室の側部内面に沿ってカーテン状に展開させる乗員拘束装置において、前記インフレータをルーフに配置し、このインフレータから左右のエアバッグに選択的にガスを供給することを特徴とする乗員拘束装置が提案される。
【0007】
上記構成によれば、ルーフに配置したインフレータから左右のエアバッグに選択的にガスを供給するので、左右のエアバッグにそれぞれ対応して2個のインフレータを設ける場合に比べて部品点数を削減することができ、しかもルーフサイドレールにインフレータを配置する場合に比べて、ルーフサイドレールと乗員の頭部との距離を確保して居住性が高めることができる。
【0008】
【発明の実施の形態】
以下、本発明の実施の形態を、添付図面に示した本発明の実施例に基づいて説明する。
【0009】
図1〜図6は本発明の第1実施例を示すもので、図1はエアバッグの非展開時の自動車の車室内面を示す図、図2はエアバッグの展開時の自動車の車室内面を示す図、図3は図1の3方向矢視図、図4は展開したエアバッグの側面図、図5は乗員拘束装置の分解斜視図、図6は図3の6−6線拡大断面図である。
【0010】
図1および図2に示すように、前列シート11、中央列シート12および後列シート13を備えたRV車は、Aピラー14、Bピラー15、Cピラー16およびDピラー17を備えており、Aピラー14およびBピラー15間にフロントドア18が配置され、Bピラー15およびCピラー16間にリヤドア19が配置され、Dピラー17の後方にテールゲート20が配置される。乗員拘束装置Cの折り畳まれたエアバッグ21は、Aピラー14およびDピラー17に挟まれたルーフ22の側部に沿って車体前後方向に収納される。尚、乗員拘束装置Cは、実質的に同一構造のものが車体の左右両側にそれぞれ設けられているが、以下その代表として車体の右側に設けられたものについて説明する。
【0011】
図4および図5から明らかなように、エアバッグ21は2枚重ねの基布31を縫製32…して構成されるもので、その上縁に沿って前後方向に延びる筒状の前側および後側のガス分配通路21a,21bを備えるとともに、前側のガス分配通路21aから下向きに分岐して前列シート11の乗員の頭部を保護する複数個のセル21c…と、後側のガス分配通路21bから下向きに分岐して中央列シート12の乗員の頭部を保護する複数個のセル21d…と、後側のガス分配通路21bから下向きに分岐して後列シート13の乗員の頭部を保護する複数個のセル21e…とを備える。
【0012】
前列シート11の乗員用のセル21c…の前方にはガスが供給されない非膨張部21fが形成され、前列シート11の乗員用のセル21c…および中央列シート12の乗員用のセル21d…の間にはガスが供給されない非膨張部21gが形成され、中央列シート12の乗員用のセル21d…および後列シート13の乗員用のセル21e…の間にはガスが供給されない非膨張部21hが形成される。そしてエアバッグ21の上縁に沿って形成された複数個の取付部21i…が、ルーフ22、Aピラー14およびDピラー17に固定される。
【0013】
折り畳まれたエアバッグ21は前後に2分割された布製のカバー33,34によって包まれる。各々のカバー33,34は下縁に沿って縫製されて筒状に構成されており、その長手方向に沿って形成したミシン目状の破断部33a…,34a…が破断することで、エアバッグ21の膨張を可能にする。エアバッグ21のの上縁に沿って形成された複数個の取付部21i…は、カバー33,34の上面に形成された開口33b…,34b…を通して上方に突出する。
【0014】
図3〜図5から明らかなように、ルーフ22の中央部にインフレータ35が左右方向(車幅方向)に配置される。インフレータ35は、例えばルーフ22の下面を補強するルーフアーチ36の凹部に保持される。インフレータ35の左右各端部から延びるガス供給パイプ37はガス分配パイプ38の中央部に接続され、その前端のガス噴出口38aが前側のガス分配通路21aの後端の前部ガス供給口21jに挿入されて固定バンド39で固定され、その後端のガス噴出口38bが後側のガス分配通路21bの前端の後部ガス供給口21kに挿入されて固定バンド40で固定される。このとき、固定バンド39,40と干渉しないように前後のガス供給口21j,21kの下方において基布31が台形状に切り取られて開口21mが形成される。
【0015】
図6から明らかなように、インフレータ35はパイプ状の圧力容器41を備えており、その内部は2個の端部隔壁41a,41aおよび1個の中央隔壁41bで2個の蓄圧室42,42に区画されており、それぞれの蓄圧室42,42に圧縮ガスが充填されている。圧力容器41の両端部には端部隔壁41a,41aを破壊するインフレータ作動手段43,43が設けられており、これらのインフレータ作動手段43,43は、側突センサ44あるいはロールオーバーセンサ45からの信号が入力される電子制御ユニット46に接続される。
【0016】
次に、上記構成を備えた本発明の実施例の作用を説明する。
【0017】
側突センサ44あるいはロールオーバーセンサ45によって車両の側面衝突やロールオーバーが検知されると、電子制御ユニット46からの指令で例えば左右一方のインフレータ作動手段43が作動して左右一方の端部隔壁41aを破壊し、左右一方の蓄圧室42に充填されたガスがガス供給パイプ37およびガス分配パイプ38を介してエアバッグ21の前後のガス分配通路21a,21bに供給され、そこから各セル21c…,21d…,21e…に流入する。その結果、折り畳み状態でルーフ22の側部に沿って収納されていた左右一方のエアバッグ21が膨張し、その圧力でルーフガーニッシュを押し下げて形成した開口を通して、エアバッグ21が車室内に下向きに展開する。展開したエアバッグ21の前側のセル21c…は前列シート11の乗員の頭部を保護し、中央のセル21d…は中央列シート12の乗員の頭部を保護し、後側のセル21e…は後列シート13の乗員の頭部を保護する。
【0018】
以上のように、ルーフ22の左右方向中央部に単一のインフレータ35を配置し、このインフレータ35から左右のエアバッグ21,21に選択的にガスを供給して展開させるので、左右のエアバッグ21,21にそれぞれ対応して2個のインフレータを設ける場合に比べて部品点数を削減することができる。またルーフサイドレールにインフレータを配置する場合に比べて、ルーフサイドレールと乗員の頭部との距離を確保して居住性が高めることができる。
【0019】
次に、図7に基づいて本発明の第2実施例を説明する。
【0020】
第1実施例のインフレータ35の圧力容器41は中央隔壁41bで2個の蓄圧室42,42に区画されているが、第2実施例のインフレータ35の圧力容器41は中央隔壁41bを備えておらず、単一の蓄圧室42が左右のエアバッグ21,21に対して設けられる。この第2実施例によっても、前記第1実施例と同様の作用効果を達成することができる。
【0021】
次に、図8および図9に基づいて本発明の第3実施例を説明する。
【0022】
第1、第2実施例のインフレータ35は車体左右方向に配置されているが、第3実施例のインフレータ35は車体中心線に沿って車体前後方向に配置されている。インフレータ35から車体前方に延びるガス入口パイプ51の先端に分配弁52が設けられており、分配弁52から左右方向に分岐する2本のガス出口パイプ53,53がガス供給パイプ37,37を介して左右のエアバッグ21,21にそれぞれ接続される。分配弁52は、電子制御ユニット46に接続されたアクチュエータ54の出力軸55に固定されて左右に回転し、ガス入口パイプ51を左右のガス出口パイプ53,53に選択的に接続するバタフライ型の弁体56を備える。
【0023】
車両の側面衝突やロールオーバーが検知されると電子制御ユニット46からの指令で分配弁52のアクチュエータ54が作動し、弁体56を左右一方に揺動させる。これと同時にインフレータ作動手段(図示せず)を作動させることで、圧力容器41内のガスを分配弁52を介して左右一方のエアバッグ21に供給することができる。
【0024】
この第3実施例によっても、単一のインフレータ35で左右のエアバッグ21,21を選択的に作動させることができるので、左右のエアバッグ21,21にそれぞれ対応して2個のインフレータを設ける場合に比べて部品点数を削減することができ、しかもルーフサイドレールにインフレータを配置する場合に比べて、ルーフサイドレールと乗員の頭部との距離を確保して居住性を高めることができる。
【0025】
次に、図10に基づいて本発明の第4実施例を説明する。
【0026】
第3実施例では分配弁52がバタフライ型の弁体56を備えているが、第4実施例の分配弁52はロータリ型の弁体56を備えている。この第4実施例によっても、前記第3実施例と同様の作用効果を達成することができる。
【0027】
尚、本発明の技術範囲には含まれないが、単一のインフレータを車体のフロアに配置し、そのインフレータから左右のエアバッグに選択的にガスを供給することができる。
【0028】
以上、本発明の実施例を詳述したが、本発明はその要旨を逸脱しない範囲で種々の設計変更を行うことが可能である。
【0029】
例えば、実施例ではインフレータ35からのガスをエアバッグ21,21の前後方向中央部に供給しているが、図3に破線で示すようにエアバッグ21,21の前部あるいは後部にガスを供給することができる。
【0030】
またインフレータ35は高圧ガスを充填したものに限定されず、推薬の燃焼により高圧ガスを発生するものであっても良い。
【0031】
【発明の効果】
以上のように請求項1に記載された発明によれば、ルーフに配置したインフレータから左右のエアバッグに選択的にガスを供給するので、左右のエアバッグにそれぞれ対応して2個のインフレータを設ける場合に比べて部品点数を削減することができ、しかもルーフサイドレールにインフレータを配置する場合に比べて、ルーフサイドレールと乗員の頭部との距離を確保して居住性が高めることができる。
