Description
また、インフレータが前方側膨張部の内部に収容され、インフレータによって発生されたガスが前方側膨張部を経由して後方側膨張部へ供給される。このため、前方側膨張部の膨張が開始した後に、後方側膨張部の膨張が開始する。これにより、クッションエアバックにおいて、着座乗員に対する押し上げ量の大きい前方側膨張部が先に膨張を開始するため、上述したサブマリン現象の発生を効果的に抑制できる。しかも、各膨張部に対応したインフレータをそれぞれ設ける必要がなくなるため、クッションエアバック装置のコストアップを抑制できる。以上により、着座乗員の頸部に対する負荷を軽減しつつ、ラップベルトによる着座乗員の腰部への拘束を維持できる。
