- 作動開始手段として機能する点火器を点火器カラー部材で保持して成る点火器組立体と、点火器の作動によって着火されてガスを生じさせるガス発生剤と、ガス発生剤を収容するカップ状部材とを含んで構成されるガス発生器であって、
カップ状部材の開放側端部には、点火器組立体における点火器カラー部材に結合する結合部が設けられ、この結合部により、カップ状部材と点火器組立体とは一体化されており、
当該カップ状部材に設けられる結合部の肉厚は、カップ状部材に於ける側壁部の肉厚よりも厚く形成されており、
前記カップ状部材の側壁部には、カップ状部材の内部で生じた圧力又は熱に対して最も脆く形成された脆弱部が設けられ、前記脆弱部は、カップ状部材の軸方向に沿う向きに延伸して形成され、かつ結合部と閉塞面側端部との間に前記側壁部を貫通することなく形成されたスリットである、ガス発生器。 - 前記結合部は、カップ状部材の開放側端部を曲折して形成されたフランジ部である請求項1に記載のガス発生器。
- 前記カップ状部材のフランジ部は、前記点火器組立体における点火器カラー部材に対してかしめにより固定されている請求項2に記載のガス発生器。
- 前記脆弱部は、カップ状部材の周方向に均等に設けられる請求項1に記載のガス発生器。
- カップ状部材に設けられている結合部の肉厚は、カップ状部材の側壁部の肉厚の1.3倍以上である請求項1〜4の何れか一項に記載のガス発生器。
