Description

【０００１】
【発明の属する技術分野】
本発明は主に助手席用エアバッグに係り、特にインフレータのガスフローを制御する整流布をエアバッグ内に配設した車両用エアバッグに関するものである。
【０００２】
【従来の技術】
自動車の助手席に装備するためのエアバッグ装置として、横倒したほぼ四角錐の形状を有し、その頂部に長方形の口元部を設けたエアバッグと、横長円筒状のインフレータと、エアバッグケースとからなり、該エアバッグケースの奥に上記インフレータを設置し、その入口側に上記のエアバッグを畳んで収納し、その口元部をエアバッグケースの開口部内壁に固定したものが知られている。
【０００３】
上記エアバッグは通常、長さ方向の中央部の幅を両端よりも広く形成した帯状の本体布をＵ字形に折曲し、その左右の側縁にほぼ三角形の側面布を縫着してほぼ横倒四角錐の形状に作られ、その頂部に設けた横長の長方形の口元部の横辺および縦辺にはそれぞれ４つの取付け布が取付けられ、また、側面布にはベントホールが開けられている。
【０００４】
このような助手席用エアバッグの一つとして、特開平５−２６２１９５号公報に記載のものがあり、これはエアバッグ袋体の内部にもう１つのインナーバッグを配設したもので、インフレータからのガスを先ずインナーバッグに噴出させた後、このインナーバッグに穿設した穴からガスを再び噴出させることによりインフレータガスの流路を規制するようになっている。
【０００５】
しかし、上記エアバッグでは、本来のエアバッグの内部にもう１体のインナーバッグを設けた２重の袋体構造となっていることから、縫製工数がかかる上に材料費等も割高となり、さらにエアバッグの折り畳み収納容積や折り畳み方法についても夫々に問題を有している。
【０００６】
【発明が解決しようとする課題】
エアバッグの展開制御を目的として、口元部下辺付近から乗員側布にかけて、エアバッグの内部を上下に区画する整流布を設けたものがあり、このエアバッグでは、上記整流布は、上記口元部下辺と乗員側布とに夫々縫着されている。
【０００７】
すなわち、このエアバッグにおいては、インフレータからのガスは、エアバッグ上部に優先して流入する一方、上記整流布側部とエアバッグの側面布との間隙を通って上部から下部へと流入するものであるが、エアバッグ上部から下部へのインフレータガスの流路が上記整流布の側部とエアバッグ側面布との間隙に限定されることから、ここを通過するガス流量が制限され、エアバッグの下部側に流入するガス量の調整が行いにくいという問題があった。
【０００８】
本発明は叙上の如き実状に対処し、整流布の一部に新規な構成を見出すことにより、上記上，下部の展開制御を行うエアバッグにおいて、上部から下部へのインフレータガス流量を自由に調整し、これによりエアバッグ上，下部の幅広い展開のタイミングを得ることを目的とするものである。
【０００９】
【課題を解決するための手段】
すなわち、上記目的に適合する本発明の車両用エアバッグの特徴は、エアバッグケースに固定される口元部の下辺部付近から乗員側布へ亘らせて、乗員側布の伸長を制限し、かつエアバッグ内部を上下に区画する整流布を取着してなるエアバッグにおいて、上記整流布の一部を折り畳んで、この折り畳み部をエアバッグの所定の展開圧力により破断する制御用縫製にて縫合すると共に、上記折り畳み部に、この折り畳みが展開することにより開口して、エアバッグの上部と下部とを連通させるインナーベントホールを形成せしめたところにある。
【００１０】
そして更に本発明は上記エアバッグにおいて、上記折り畳み部とエアバッグの上面布とに亘らせて、この上面布の伸長を制限するストラップを取着すると共に、このストラップの折り畳み部側の取り付けを折り畳み部の制御用縫製によって行い、このストラップの緊張を上記制御用縫製の破断のきっかけにすることも特徴とする。
【００１１】
【作用】
上記本発明のエアバッグにおいては、エアバッグの上部がほぼ膨張しかけた時点で上記整流布の折り畳み部が展開して、インナーベントホールが開口し、このインナーベントホールを通じてエアバッグの下部側へインフレータガスが流入する。
【００１２】
即ち、本発明のエアバッグでは、このインナーベントホールの数量と開口面積を調整することにより、エアバッグの上部から下部へ流れるインフレータガスの流量を自由に設定することができ、これによりエアバッグ上部と下部の幅広い展開のタイミングを得ることが可能となる。
【００１３】
【実施例】
以下さらに添付図面を参照して、本発明の実施例を説明する。
【００１４】
図１（Ａ）は本発明実施例の助手席用エアバッグの展開初期を示す透視図、同図（Ｂ）は同、断面図、図２（Ａ）は同エアバッグの展開終了時を示す透視図、同図（Ｂ）は同、断面図、図３は図２（Ａ）のＢ−Ｂ線断面図、図４は同エアバッグの折り畳み部を示す拡大図である。
【００１５】
このエアバッグは、長さ方向の中央部の幅を両端よりも広く形成した帯状の本体布１をＵ字形に折曲し、その左右の側縁にほぼ三角形の側面布２を縫着してほぼ横倒四角錐の形状に作られ、その頂部に設けた横長の長方形の口元部３は、エアバッグケース（図示せず）の開口部に固定されるようになっている。
【００１６】
上記エアバッグでは、上記口元部３の下辺部４付近から乗員側布５へ亘らせて、乗員側布５の伸長を制限し、かつエアバッグ内部を上下に区画する整流布６を取着している。
【００１７】
そして、図１，図４に示す如く、上記整流布６の一部を車両の前後方向に折り畳んで、この折り畳み部７をエアバッグの所定の展開圧力により破断する制御用縫製８にて縫合すると共に、上記折り畳み部７に、この折り畳みが展開することにより開口して、エアバッグの上部と下部とを連通させる２個の大径インナーベントホール９を形成せしめている。
【００１８】
またさらに、上記エアバッグの上部側に突出する折り畳み部７とエアバッグの上面布１０とに亘らせて、この上面布１０の伸長を制限するストラップ１１を取着し、図４に示す如く、このストラップ１１の折り畳み部７側の取り付けを折り畳み部７の制御用縫製８により行っている。ストラップ１１の折り畳み部７側の取り付けは、剥離が行われやすいようにＵ字状に折り曲げた状態でなされている。
【００１９】
一方、上記整流布６は、乗員側布５側と口元部３側とは、全部またはほぼ全部に縫着するが、側面布２側は図２（Ａ）に示す如く一部を縫着するようにしてもよく、あるいは全て縫着するか全く縫着しないかも適宜に選択しうる。
【００２０】
しかして、上記本発明実施例のエアバッグにおいては、図１に示す如くエアバッグの上部がほぼ膨張しかけた時点でストラップ１１が緊張して制御用縫製８の一部を切断し、これをきっかけとして図２に示す如く全ての制御用縫製８が切れる。これにより、上記整流布６の折り畳み部７が展開して、図１に示す状態から図２，図３に示す状態へとインナーベントホール９が開口し、図２（Ｂ）に示す如く、このインナーベントホール９を通じてエアバッグの下部側へインフレータガスが流入する。
【００２１】
この場合、整流布６の側部と側面布２との間を、全部縫製せずに開けておくことにより、この間隙を利用してインフレータガスの流入を図ることが可能である。
【００２２】
即ち、上記本発明実施例においては、上記インナーベントホール９の数量と開口面積とを調整することにより、エアバッグの上部から下部へ流れるインフレータガスの流量を自由に設定することができ、これによりエアバッグの上部と下部との夫々における幅広い展開のタイミングを獲得することが可能である。
【００２３】
以上、本発明の実施例を説明したが、上記整流布の構成を逆にすることにより、エアバッグの下部側から上部側へと展開を進めることも可能である。
【００２４】
すなわち、この場合は、前記口元部３の下辺に取着していた整流布６の基端部を口元部３の上辺またはその付近に取着する。そして折り畳み部７は、折り方向はそのままでエアバッグの下部側に突出するように折り畳み、ストラップ１１はこの下向きの折り畳み部とエアバッグの下面布とに亘るように取着する。
【００２５】
【発明の効果】
以上説明したように、本発明の車両用エアバッグは、エアバッグの口元部下辺から乗員側布にかけエアバッグ内を上下に区画する整流布を取着したエアバッグにおいて、上記整流布の一部を折り畳んで、この折り畳み部をエアバッグの所定の展開圧力により破断する制御用縫製にて縫合し、かつ、上記折り畳み部に、この折り畳み部が展開することにより開口して、エアバッグの上部と下部とを連通させるインナーベントホールを形成すると共に、折り畳み部とエアバッグ上面布とに亘らせてストラップを取着し、折り畳み部の制御用縫製を共用して取り付けたものであり、ストラップの緊張を破断のきっかけにしてエアバッグの上部がほぼ膨張しかけた時点で制御用縫製が切断し、これにより上記整流布の折り畳み部が展開して、インナーベントホールが開口し、このインナーベントホールを通じてエアバッグの下部側へインフレータガスが流入することができ、その結果、このインナーベントホールの数量と開口面積を調整することにより、エアバッグの上部から下部へ流れるインフレータガスの流量を自由に設定することができ、これによりエアバッグ上部と下部の夫々における幅広い展開のタイミングを得ることができる優れた効果を奏するものである。
