The invention provides a side air curtain device and a folding method, and relates to the technical field of automobile safety, the side air curtain device comprises an air bag body and an air generator, the air bag body comprises a main chamber, an air guide bag and a small air bag chamber; the main cavity is formed by a first main cloth piece and a second main cloth piece, the first main cloth piece is arranged close to the metal plate side, and the second main cloth piece is arranged close to the passenger side. The air guide bag is arranged in the small air bag cavity, the air generator is installed in the air guide bag, and a flow guide hole is formed in the air guide bag; the gas generator generates gas to enter the gas guide bag, and the flow guide hole guides the gas flowing into the gas guide bag to the small gas bag cavity. The two sides, in the vehicle length direction, of the small air bag cavity are in a tearable state or an open state, and after air in the air guide bag flows into the small air bag cavity, the small air bag cavity is bulged and breaks through the two sides of the small air bag cavity to flow into the main cavity. By arranging the main cavity, the air guide bag and the small air bag cavity, when the air bag body is unfolded, the air bag body can cross and does not damage the stand column decoration plate, the structure is simple, and installation is easy.

    本申请提供一种侧面气帘装置及折叠方法,涉及汽车安全技术领域,其包括气袋本体和气体发生器,气袋本体包括主腔室、导气袋及小气袋腔室;主腔室由主布片一和主布片二形成,主布片一靠近钣金侧设置,主布片二靠近乘员侧设置;导气袋设置于小气袋腔室内,气体发生器安装于导气袋内,导气袋上设置有导流孔;气体发生器产生气体以进入导气袋内,导流孔将流入导气袋的气体导向小气袋腔室;小气袋腔室沿车长方向的两侧为可撕裂状态或者开口状态,导气袋内的气体流入小气袋腔室后,使得小气袋腔室鼓起,并突破小气袋腔室的两侧流入主腔室。通过设置主腔室、导气袋及小气袋腔室,使得气袋本体在展开时,可以越过且不破坏立柱饰板,且结构简单,容易安装。
