A plurality of thickness reducing areas are formed at the top end of the bag, a plurality of buffer areas are formed between the sewing areas and top end sewing threads of the bag, a first-stage air guide opening communicated with the buffer areas is formed between the top end sewing threads of each sewing area and the top end sewing threads of the bag, and the expansion size of the first-stage air guide opening is smaller than that of an air inlet of the protection cavity. And the air flowing out of the air outlet of the air guide bag is shunted. According to the side air curtain, the multiple thickness reducing areas are formed at the top end of the bag when the bag is inflated so as to avoid the automobile ceiling interior trim part, and the problem that in the prior art, after the side air curtain is unfolded, the top of the side air curtain easily impacts the ceiling interior trim part, and consequently the ceiling interior trim part is disengaged is solved.

    本发明公开了一种侧气帘,包括囊袋和导气袋,囊袋内至少设有至少一保护腔,导气袋设置于囊袋内,且导气袋的至少一出气口朝向保护腔的进气口,囊袋还包括多个缝纫区,多个缝纫区间隔缝纫于囊袋的顶端,并在囊袋的顶端形成多个减厚区域,且多个缝纫区与囊袋的顶端缝线之间形成多个缓冲区,每一缝纫区的顶端缝线与囊袋的顶端缝线之间形成连通缓冲区的一级导气口,一级导气口的膨胀尺寸小于保护腔的进气口的膨胀尺寸,以对导气袋出气口流出的气体进行分流。本发明通过在囊袋充气时在囊袋的顶端形成多个减厚区域,以避让汽车顶棚内饰件,解决了现有技术中侧气帘展开后侧气帘顶部易冲击顶棚内饰件导致顶棚内饰件脱离的问题。
