The invention provides an overhead safety air bag. The overhead type safety air bag comprises an air bag, an air bag body and a control device, wherein the air bag body has an unfolded state and a folded state; the gas generator is used for inflating the air bag so as to enable the air bag to be expanded to enter an unfolded state; wherein the air bag comprises a first air bag used for defining a first air bag cavity and a second air bag used for defining a second air bag cavity, the second air bag is fixed to the outer side surface of the first air bag and comprises two end parts and a middle part located between the two end parts, and in the unfolded state, the first air bag and the second air bag are arranged in a staggered mode. The two end parts are respectively positioned on side panels of the first air bag, the middle part is positioned on a top panel of the first air bag, and the two end parts both protrude out of a front panel of the first air bag and define a concave part together with the front panel; and the middle part protrudes out of the front panel and forms an opening and closing part with a variable opening and closing degree together with the top panel.
本发明提供一种顶置式安全气囊。该顶置式安全气囊包括:气袋,其具有展开状态和收纳状态;和气体发生器,其用于对所述气袋充气以使所述气袋膨胀而进入展开状态;其中,所述气袋包括分别用于界定第一气袋腔室的第一气袋和用于界定第二气袋腔室的第二气袋,所述第二气袋被固定在所述第一气袋的外侧表面上,并且,包括两个端部和位于所述两个端部之间的中间部,在展开状态下,两个所述端部分别定位于所述第一气袋的侧面板,所述中间部定位于所述第一气袋的顶面板,两个所述端部均凸出于所述第一气袋的前面板并且与所述前面板共同限定凹陷部,以及,所述中间部凸出于所述前面板并且与所述顶面板共同形成具有可变开合度的开合部。
