The embodiment of the invention provides a side air curtain, and relates to the technical field of automobile accessories. A side face air curtain comprises a bag, an air generator, a support and a belt-shaped piece, the bag comprises a main cavity and an air inlet part, the air inlet part is tubular and extends in the direction away from the main cavity, the belt-shaped piece surrounds the support and the air generator inserted into the air inlet part and is fixed, the bag comprises a sealing part, and the sealing part is formed by combining a sealant material with a cloth piece. The sealing part is wound along the outer part of the gas inlet part, and at least part of the sealing part is propped against the outline edge of the bracket and/or is arranged in an overlapping area between the bracket and the gas inlet part inserted into the gas generator, so that the sealing part is deformed under the fastening action of the belt-shaped piece; and a gap generated between the strip-shaped piece and the surface of the air inlet part due to the fall between the surface of the bracket and the surface of the air generator is sealed. According to the treatment scheme, when the gas curtain is exploded, gas leakage from gaps can be avoided, and the pressure maintaining effect of the gas curtain is improved.
本说明书实施例提供一种侧面气帘,涉及汽车配件技术领域。一种侧面气帘包括囊袋、气体发生器、支架和带状件,囊袋包括主腔和进气部,进气部呈管状且向远离主腔的方向延伸,带状件包围支架及插入进气部的气体发生器并固定,囊袋包括封闭部,封闭部由密封胶材料结合布片而成,封闭部沿进气部外部卷绕,至少有部分封闭部抵接支架轮廓边缘和/或置于支架与插入气体发生器的进气部间的重叠区域,以使在带状件的紧固作用下,封闭部发生形变,封闭由于支架表面和气体发生器表面的落差造成的带状件和进气部表面间产生的缝隙。通过本申请的处理方案,可使得气帘点爆时,避免气体由缝隙泄漏,提高气帘的保压效果。
