Description
Claims (3)
- ガス圧力容器(7)から流出するガスを利用してガスバッグを膨張させるための冷ガス発生器であって、前記ガス圧力容器(7)は、格納されたガスに対して反対方向に湾曲し、かつ、前記ガス圧力容器(7)にガスが充填された状態において、少なくとも1の吐出開口部(11)を介してガスバッグに連通する空間(12)内に、完全に露出した態様で配向される破壊可能な膜(2)により閉鎖される吐出開口部(1)を備え、前記膜(2)は、ノズルチャンバ(5)を介して前記空間(12)内に案内され、格納されたガスに対して反対方向に湾曲した前記膜(2)の最上点(6)で集束する高温ガス噴射による部分的な加熱により弱化され、その後、前記ガス圧力容器の内圧により破壊され、高温ガス噴射は、電気パルスの印加により作動可能なプライマ(4)の点火によってのみ生じる、冷ガス発生器。
- プライマ(4)は、ハウジング(8)で囲まれた推進剤装入物(10)を備え、前記装入物は、装入物内に案内される点火ピン(9)を介して点火可能であることを特徴とする請求項1に記載の冷ガス発生器。
- 前記膜(2)の最上点とノズルチャンバ(5)の吐出開口部(13)との距離が、ガス圧力容器(7)の吐出開口部(1)の径より小さいか、または、等しいことを特徴とする請求項1または2に記載の冷ガス発生器。
