The invention discloses a safety air bag which comprises a main air bag, an air guide bag main piece and an air generator, an air generator placing opening is formed in the main air bag, the air guide bag main piece and the air generator are both arranged in the main air bag, and the side edge of the first end of the air guide bag main piece is connected with the fixed lower edge of the air generator placing opening; the safety air bag further comprises a first anti-deflection piece, the first anti-deflection piece is arranged at the edge position of the second end of the air guide bag main piece, the first end of the first anti-deflection piece is connected with the second end of the air guide bag main piece, and the second end of the first anti-deflection piece is connected with the periphery of the main air bag. Compared with the prior art, the degree of freedom of the air guide bag is reduced, the situation that the air guide bag is impacted by high-temperature gas generated by the gas generator to move irregularly is avoided, and the problem that due to the fact that an existing air guide bag is high in flexibility in the main air bag, main cloth pieces of the air guide bag can be impacted by the high-temperature gas, and the hole breaking risk exists is solved.

    本发明公开了一种安全气囊,包括主气袋、导气袋主片和气体发生器,主气袋上设置有气体发生器放入口,导气袋主片和气体发生器均设置于主气袋内,导气袋主片的第一端侧边与气体发生器放入口的固定下边缘连接;安全气囊还包括第一防偏转片,第一防偏转片设置于导气袋主片第二端的边缘位置,第一防偏转片的第一端与导气袋主片的第二端连接,第一防偏转片的第二端与主气袋的外周连接。本发明相对于现有技术降低了导气袋的自由度,避免导气袋被气体发生器产生的高温气体冲击进行无规则运动,解决了现有的导气袋在主气袋中灵活度高而导致导气袋的主布片会被高温气体冲击而存在破孔风险的问题。
