The invention relates to the field of automobile safety air bags, in particular to a gas generator and a safety air bag. The gas generating part is arranged in the guide pipe, and the electric explosion unit is used for igniting the gas generating part, so that gas is quickly generated. When the gas generating piece is not ignited, the blocking piece blocks the barrel, the sealing performance of the gas generator is guaranteed, and gas leakage is avoided. When the gas generating part rapidly combusts to generate gas, the plugging part is stressed and is damaged under the action of force, so that the barrel is communicated with the outside, and the gas flows to the outside. According to the gas generator, a rupture disk and other structures are omitted, the structure is simpler, the cost is lower, the sealing performance is improved, gas leakage is avoided, and therefore the gas bag can be rapidly inflated.
本发明涉及汽车安全气囊领域,具体而言,涉及一种气体发生器及安全气囊。本发明通过在导管内设置产气件,并利用电爆单元引燃产气件,从而快速产生气体。在产气件未被引燃时,封堵件封堵筒体,保证气体发生器的密封性,避免气体泄露。在产气件快速燃烧产生气体时,封堵件受力导致其自身在力的作用下被破坏,从而使得筒体和外界连通,使得气体流动至外界。该气体发生器减少了爆破片等结构,其结构更简单,成本更低,并且提高了密封性,避免气体泄露,从而实现对气囊的快速充气。
