- エアバッグクッションに形成され、内部の膨張ガスを排出するように構成されているメインベントホールと、
前記エアバッグクッションの外側面に設けられ、提供される引張力によって前記メインベントホールと離隔して前記メインベントホールを開放した状態と、前記メインベントホールに密着して前記メインベントホールを閉鎖した状態とを切り替えるように構成されているカバーと、
前記カバーに一端部が連結され、他端部が前記エアバッグクッションの内部に固定されて、前記メインベントホールを介して前記カバーに引張力を提供するように構成されているテザーと、
周縁が前記エアバッグクッションの内側面に固定されて前記エアバッグクッションとの間に空間を形成し、前記テザーが通過して支持される状態で摺動するように構成されているテザーガイドと、
前記エアバッグクッションの内部に前後端および両端が固定されて前記エアバッグクッションの展開形状を規制する形状維持テザーと、を含み、
前記形状維持テザーの前端部が、前記テザーの他端部とともに前記エアバッグクッションの前方に固定されていることを特徴とする車両のエアバッグ装置。 - 前記メインベントホールと前記テザーガイドとの間に設けられて前記テザーを支持し、前記テザーガイドを通過した前記テザーが前記エアバッグクッションの内側面に摺動しながら通過するように構成されている密閉ガイドをさらに含むことを特徴とする請求項1に記載の車両のエアバッグ装置。
- 前記カバーには、前記エアバッグクッションの内部の膨張ガスを排出するように補助ベントホールが形成され、前記補助ベントホールは、前記カバーが前記メインベントホールを閉鎖した状態で前記メインベントホールの内側または外側に位置するように形成されていることを特徴とする請求項1に記載の車両のエアバッグ装置。
- 前記カバーは、前記メインベントホールの周囲を囲むように前記エアバッグクッションに一部が接合し他の部分は開放されて、前記エアバッグクッションの外側面とともに前記メインベントホールから放出した膨張ガスを大気中に排出させるポケット状の排出口を形成するように構成されていることを特徴とする請求項1に記載の車両のエアバッグ装置。
- 前記メインベントホールは、前記エアバッグクッションの側面に形成され、
前記テザーガイドは、前記エアバッグクッションに搭乗者の頭が接触する部分の内側に設置されていることを特徴とする請求項1に記載の車両のエアバッグ装置。 - 前記テザーガイドが固定された前記エアバッグクッションの外面は、その周縁のエアバッグクッションの外面より搭乗者に向かって突出した状態で展開されるように構成されていることを特徴とする請求項5に記載の車両のエアバッグ装置。
