The invention relates to the technical field of safety air bags, and provides an air bag folding method, an air bag and an overhead safety air bag. An air bag of the overhead safety air bag is provided with an inflation part used for being connected with an air generator and an extension part extending from the inflation part. The air bag folding method comprises the steps that the air bag is spread out, the stretching part is spread out, the inflation part is stacked on the back face of the stretching part, and the back face of the stretching part faces a protected object in an inflation unfolding state; and the two ends of the spread extending part are opposite to the inflation part and are folded oppositely until the two ends of the extending part are overlapped. According to the overhead safety air bag, by improving the folding mode of the air bag, the air bag of the overhead safety air bag can be prevented from hitting a protected object in the inflation and unfolding process, potential safety hazards are avoided, and therefore stable and reliable anti-collision protection can be provided.

    本发明涉及安全气囊技术领域,提供一种气袋折叠方法、气袋和顶置式安全气囊。顶置式安全气囊的气袋具有用于连接气体发生器的充气部和自所述充气部延伸的伸展部;气袋折叠方法包括:铺展所述气袋,使所述伸展部铺平、所述充气部叠置于所述伸展部的背面,所述伸展部的背面在充气展开状态下朝向被保护对象;将铺平的所述伸展部的两端背向所述充气部、且相向翻折,至所述伸展部的两端相重叠。本发明能够通过气袋折叠方式的改进,使顶置式安全气囊的气袋在充气展开过程中避免弹打被保护对象,以避免安全隐患,从而能够提供稳定可靠的防撞保护。
