The invention discloses a side air curtain which comprises a bag, the bag comprises an air inlet, an air guide channel is formed in a bag area located below the air inlet, a pull belt is arranged at the front end of the bag, and the bag further comprises a top cavity sewing thread and an oblique direct filling cavity. The head end of the top cavity sewing thread is connected with a top end sewing thread of the bag and extends towards the front end of the bag to be matched with the top end sewing thread of the bag to form a top buffer cavity, and a buffer air inlet of the top buffer cavity is formed between the tail end of the top cavity sewing thread and the top end sewing thread of the bag and/or the front end sewing thread of the bag; the oblique direct inflation cavity is formed below the top buffering cavity and extends from the front end of the air guide channel to the lower portion of the front end of the bag, and the end, away from the air guide channel, of the oblique direct inflation cavity communicates with the top buffering cavity. The front end of the side air curtain can be prevented from floating outwards from the vehicle window, and the problem that in the prior art, the air curtain is only rolled and folded, so that the air curtain interferes with the edge of the vehicle window or floats out of the vehicle window when unfolded is solved.

    本发明公开了一种侧气帘,包括囊袋,囊袋包括进气口,位于进气口下方的囊袋区域形成有导气通道,囊袋的前端端部设有拉带,囊袋还包括顶部腔体缝线和斜向直充腔。顶部腔体缝线的首端与囊袋的顶端缝线连接,并向囊袋的前端延伸以配合囊袋的顶端缝线形成顶部缓冲腔,且顶部腔体缝线的尾端与囊袋的顶端缝线和/或囊袋的前端缝线之间形成顶部缓冲腔的缓冲进气口;斜向直充腔形成于顶部缓冲腔的下方,斜向直充腔从导气通道的前端向囊袋的前端下部延伸,且斜向直充腔远离导气通道的一端与顶部缓冲腔连通。本发明能够避免侧气帘前端从车窗向外飘,解决了现有技术中气帘只卷折导致气帘展开时与车窗边缘干涉或飘向车窗外的问题。
