    • An airbag includes two base cloths sewn together at their outer peripheries by a seam extending from a central portion to the outer periphery of the base cloths into a vortical shape. When gas is supplied from an inflator to a center aperture of one of the base cloth to inflate the airbag, load generated by gas pressure breaks the seam sequentially from the central portion to the outer periphery, preventing sudden deployment of the airbag in fore and aft directions at the initial stage of deployment, thereby enabling not only soft restraining of passengers but also sufficient restraining by deploying the airbag into a final shape that is flat in fore and aft directions upon completion of breaking of the seam.
    • 安全气囊包括通过从基布的中心部分延伸到外围的接缝形成涡卷形状的缝合在其外周的两个基布。 当气体从充气机供应到基布之一的中心孔以使气囊膨胀时,由气压产生的载荷从中心部分到外周依次断开接缝,防止气囊在前后突然展开 在部署的初始阶段的方向,从而不仅能够轻松地限制乘客,而且还能够通过在完成接缝断裂之后将气囊展开成前后平坦的最终形状来进行充分的约束。
