Abstract
【解決手段】車両が衝突した際乗員側へ膨張展開されるエアバッグ本体1と、エアバッグ本体の展開状態に応じてベントホール6c、6eの開度を複数段階に調整自在な内圧調整手段6と、内圧調整手段に一端側が接続されたテザーベルト7と、テザーベルトの他端側を係脱自在に係止する係止手段4とを備え、シートベルト着用時に車両が衝突した際には、エアバッグ本体の展開初期に内圧調整手段を全開状態にし、その後エアバッグ本体が最終展開状態となるまで内圧調整手段を半開状態に維持すると共に、シートベルト着用せずに車両が衝突した際には、エアバッグ本体の展開初期を過ぎたときから最終展開状態まで内圧調整手段を全閉状態に維持するようにした。

Claims (3)
- 車両が衝突した際インフレータより噴出される高圧ガスにより乗員側へ膨張展開されるエアバッグ本体と、前記エアバッグ本体に設けられ、かつ前記エアバッグ本体の展開状態に応じてベントホールの開度を複数段階に調整自在な内圧調整手段と、前記内圧調整手段に一端側が接続されたテザーベルトと、前記テザーベルトの他端側を係脱自在に係止する係止手段とを備え、
展開状態における前記エアバッグ本体が低反力を必要とするときには、前記係止手段により前記テザーベルトの他端側を係止して、前記エアバッグ本体の展開初期に前記内圧調整手段を全開状態にし、その後前記エアバッグ本体が最終展開状態になるまで前記内圧調整手段を半開状態にし、
展開状態における前記エアバッグ本体が高反力を必要とするときには、前記係止手段による前記テザーベルトの係止を解除して、前記エアバッグ本体の展開初期を過ぎたときから最終展開状態まで前記内圧調整手段を全閉状態にすることを特徴とするエアバッグ装置。 - 前記内圧調整手段を、前記エアバッグ本体内と連通する有底のカバーと、前記カバーの底部に開口された外側ベントホールと、前記底部の内側に接離自在に縫着され、かつ前記外側ベントホールと互い違いとなる位置に内側ベントホールが開口された弁部材とから構成し、前記テザーベルトの一端側を前記弁部材に接続してなる請求項1に記載のエアバッグ装置。
- 前記係止手段を、シートベルト着用時に車両の衝突が発生した場合は前記テザーベルトの係止状態を維持し、シートベルトを着用していないときに衝突が発生した場合に前記テザーベルトの係止状態を解除するパイロアクチュエータ或いは電磁ソレノイドにより形成してなる請求項1または2に記載のエアバッグ装置。
