    • An inflatable bag for airbag passive restraints for driver which comprises upper and lower circular base cloths of the same size seamed together at their outer peripheries and lateral regulating means for regulating inflation of the bag in lateral and upward directions and causing downward inflation, which means extends to link between an inner periphery of the lower base cloth and the outer peripheries in a shorter length than the radial distance therebetween, thus forming a sag portion on the lower cloth. When the bag is deployed, the lateral regulating means enables the sag portion to bulge sideways out of a steering wheel to protect a driver. The bag may further include upward restricting means for upward inflation. The lateral and the upward regulating means may be located in a whole circumferential area or within a range of 1/2 to 1/4 the circumference of both cloths. A method of producing the bag having lateral or both regulating means is characterized by using a third cloth of the same size having strap-like portion or portions defined by communicating hole or holes. After superposing and sewing of the lower, upper and third cloths, the strap-like portions are each raised and folded into two and sewn at two roots, thus forming the lateral means. Then the folded strap-like portions are cut at one root and the unfolded strap ends are sewn to the upper base cloth to form upward strap members.
    • 一种用于驾驶员的气囊被动约束装置的充气袋,其包括在其外围处接合在一起的相同尺寸的上下圆形基布和侧向调节装置,用于调节袋在侧向和向上方向上的膨胀并引起向下膨胀,这意味着延伸 在下基布的内周和外周之间以比其间的径向距离更短的长度连结,从而在下布上形成下垂部。 当袋部署时,侧向调节装置使得下垂部分从侧向凸出方向盘以保护驾驶员。 袋子还可以包括用于向上膨胀的向上限制装置。 横向和向上调节装置可以位于两个布的整个圆周区域中或在两个布的圆周的1/2至1/4的范围内。 制造具有侧面或两个调节装置的袋的方法的特征在于使用具有由连通孔或孔限定的带状部分或部分的具有相同尺寸的第三布。 在下,上和第三布的叠加和缝合之后,将带状部分分别升高并折叠成两个,并在两个根部缝合,从而形成横向装置。 然后将折叠的带状部分在一个根部切割,并将展开的条带端部缝合到上部基布上以形成向上的带状部件。
