Claims (5)
- 乗員保護部の中央に凹部を備えた展開形状をなすエアバッグと、
前記乗員保護部側の展開を一部規制することによって前記凹部を非規制時よりも深く形成する規制手段と、
個別に点火制御可能な複数のインフレータ部を有する多段式のインフレータと、
車速センサ及び加速度センサからの信号に基づいて車両の衝突を判定し、前記インフレータの点火制御を行う制御手段と、を備え、
前記規制手段は、前記エアバッグの展開時の内圧が設定圧力以上となったとき前記規制を解除するよう構成され、
前記制御手段は、前記インフレータの前記各インフレータ部の点火タイミングを制御することによって前記エアバッグの最大内圧を制御する点火制御パターンとして、前記エアバッグの展開時における最大内圧を前記設定圧力以上に制御する第1の制御パターンと、前記エアバッグの展開時における最大内圧を前記設定圧力未満に制御する第2の制御パターンとを有し、加速度が閾値以上で且つ車両が設定車速以上の大衝突を判定して前記第1の制御パターンを選択したときは前記エアバッグ展開時の内圧により前記規制を解除させ、加速度が閾値以上で且つ車速が前記設定車速未満の小衝突を判定して前記第2の制御パターンを選択したときは前記エアバッグ展開時の内圧により前記規制を解除させないことを特徴とするエアバッグ装置。 - 前記規制手段は、エアバッグの基部側と前記乗員保護部側とを連結する連結部材で構成されたことを特徴とする請求項1に記載のエアバッグ装置。
- 前記規制手段は、前記エアバッグ展開時の内圧によって中途が断裂されることにより、前記規制を解除することを特徴とする請求項2に記載のエアバッグ装置。
- 前記規制手段は、断裂用のスリット部を有することを特徴とする請求項3に記載のエアバッグ装置。
- 前記規制手段は、中途が折り返されて縫合された縫合部を有し、前記エアバッグの展開時の内圧によって当該縫合部が解放されることにより、前記規制を解除することを特徴とする請求項2に記載のエアバッグ装置。
