Description
本発明のエアバッグ装置21は、車両の衝突時や横転時に、車両用シート9に着座した乗員12の頭部12aと、例えば肩部12b・上腕部12c・胸部12dの側方部を覆うように膨張展開するエアバッグ22と、当該エアバッグ22の内部にガスを噴出するインフレータ3を備えている。エアバッグ22は、その左右に、対称な同一形状のチャンバ2cがそれぞれ形成されている。チャンバ2cは、膨張展開が完了した膨張完了状態において、乗員12の頭部12a(具体的には、頭頂部から側頭部)を覆う頭部保護チャンバ2cbと、乗員12の側方部を覆う側部保護チャンバ2caとを有している。なお、チャンバ2c、側部保護チャンバ2ca、及び頭部保護チャンバ2cbについて、「チャンバ」とは、内部空間だけでなく、その内部空間を形成するシートを含む袋体を意味する。
・インフレータ3の取付け位置をエアバッグ22の左右両側の下部とした点。
・例えばロール状に巻いた状態のエアバッグ22の、車両用シート9の背もたれ部9aへの取付け端22c側から延びる外周部分の一部に付加折り返し部22aを設けた点。
・左右方向中央部の縫製部5に通気口24を設けて左右のチャンバ2cを連通させている点。

Claims (5)
- 車両用シートに着座した乗員の頭部と側方部を一体的に覆うように膨張展開するエアバッグと、当該エアバッグにガスを供給するインフレータと、を備えたエアバッグ装置であって、
前記エアバッグは、
膨張展開が完了した膨張完了状態において、乗員の頭部を覆う頭部保護チャンバと、乗員の側方部を覆う側部保護チャンバとを有すると共に、
ロール状に巻いた状態または蛇腹状に折り畳んだ状態で、車両用シートの背もたれ部の一方側部から上部を経由して他方側部に亘って収納される収納状態において、前記収納状態のエアバッグの前記背もたれ部への取付け端側から延びる外周部分に付加折り返し部を有し、
前記付加折り返し部は、前記収納状態のエアバッグのうち、ロール状に巻かれたまたは蛇腹状に折り畳まれた部分の少なくとも後側の一部分を覆うように設けられており、
前記エアバッグは、膨張展開初期の段階で、前記付加折り返し部が、前記頭部保護チャンバ及び前記側部保護チャンバよりも先に膨張展開するように構成されており、先に膨張展開した前記付加折り返し部は、前記車両用シートに着座した乗員とは反対側の位置に前記エアバッグの膨張展開方向を決める案内壁を形成する、エアバッグ装置。 - 前記付加折り返し部は、前記背もたれ部の表面近傍から前記収納状態のエアバッグの後側の外周部分の形状に沿って上部近傍まで延び、当該上部近傍で下方に向かって折り返されて前記背もたれ部の表面近傍まで達するように設けられている、請求項1に記載のエアバッグ装置。
- 前記付加折り返し部は、前記収納状態のエアバッグの頂上部分も更に覆うように設けられている、請求項1又は2に記載のエアバッグ装置。
- 前記付加折り返し部は、前記頂上部分を経て当該頂上部分から連続する、前記収納状態のエアバッグの前側の上部の一部分も覆うように設けられている、請求項3に記載のエアバッグ装置。
- 前記付加折り返し部は、少なくとも前記頭部保護チャンバに相当する部分に設けられている、請求項1~4の何れか1項に記載のエアバッグ装置。
