The invention relates to the field of automobile safety, in particular to a ceiling curtain type safety airbag for a vehicle, which comprises an airbag assembly, a gas generator and a dry hanging ring assembly, a skylight guide rod assembly comprises a guide rod and a guide rod limiting block arranged on the guide rod, and the whole guide rod limiting block is provided with a guide slope and a stop surface; the lifting ring assembly comprises a lifting ring body and a lifting ring limiting piece, the lifting ring limiting piece is provided with a guide rod mounting hole and a lifting ring sliding hole, and an elastic lifting ring guide stop piece is arranged on the inner side face of the lifting ring sliding hole. According to the technical scheme, when a vehicle rolls and collides, the air bag assembly can be rapidly expanded and unfolded along the air bag guide rod assembly to cover the skylight, the position of the air bag assembly is restrained through cooperation of the guide rod limiting block and the hanging ring guide stop piece after the air bag assembly is unfolded, the displacement amount of the air bag when a passenger collides with the air bag is reduced, and the safety of the passenger is improved. Therefore, the protection performance of the ceiling curtain type safety air bag is maximized.
本发明涉及汽车安全领域,具体为一种用于车辆的顶棚帘式安全气囊,包括气袋总成,气体发生器,干吊环总成,天窗导向杆总成包括导向杆以及设置在导向杆上的导向杆限位块,导向杆限位块整体具有导向斜坡以及止动面;吊环总成包括吊环本体和吊环限位件,吊环限位件具有导向杆安装孔和吊环滑动孔,吊环滑动孔内侧面上设置有具有弹性的吊环导向止动片。本发明技术方案在车辆发生翻滚碰撞时,气袋总成能够沿着气袋导向杆总成快速膨胀展开,覆盖天窗,并在展开后通过导向杆限位块与吊环导向止动片的配合约束气袋总成的位置,减少乘员撞击到气袋时气袋的位移量,从而使得顶棚帘式安全气囊的保护性能最大化。
