The side air curtain comprises an air bag, an air generator and a support, the air bag is provided with a connecting port matched with the air generator, an air outlet of the air generator is inserted into the connecting port and then installed on the support, the side air curtain further comprises an elastic piece and a clamping ring, a plurality of through holes are formed in the support, and the elastic piece is connected with the clamping ring. The elastic piece penetrates through the through hole to wind the gas generator, the gas bag and the support together for first-stage closing-in fastening, and the clamping ring is tightly hooped outside the elastic piece for second-stage closing-in fastening. The elastic piece and the clamping ring are arranged, meanwhile, the through hole for the elastic piece to penetrate through is formed in the support, the elastic piece penetrates through the through hole to enable the gas generator, the gas bag and the support to be wound together, then the clamping ring is used for hooping the gas generator, the gas bag and the support to conduct first-stage closing-in fastening and second-stage closing-in fastening, and displacement between the gas generator and the support can be avoided; meanwhile, gas leakage is avoided.
本说明书实施例提供一种侧气帘,侧气帘包括气袋、气体发生器和支架,气袋上设有与气体发生器相配合的连接口,气体发生器的出气口插入连接口内,再安装于支架上,侧气帘还包括弹性件和卡环,支架上开设有若干通孔,弹性件穿过通孔将气体发生器、气袋及支架一并缠绕在一起进行一级收口紧固,卡环紧箍于弹性件外部进行二级收口紧固。通过设置弹性件和卡环,同时在支架上开设用于弹性件穿过的通孔,通过将弹性件穿过通孔将气体发生器、气袋及支架一并缠绕在一起再用卡环箍紧来进行一级收口紧固和二级收口紧固,能够避免气体发生器与支架之间产生窜动位移,同时避免气体泄漏。
