    • A light, inexpensive air bag having improved rebound preventing characteristics and obtained through the steps of forming a bag body (1), which has a gas generator fixing opening (4), by combining (9) the circumferential portions of at least two pieces of woven cloths (2, 3), and providing films (5, 6, 7, 8) of coating on predetermined parts of the outer surface of the bag body (1) so that these films (5, 6, 7, 8) work as both bag body-reinforcing members and driver-protecting members, with the areas of regions (2a, 3a), on which the films (5, 6, 7, 8) of coating are not provided, determined suitably in accordance with the gas-permeability of the woven cloths (2, 3) to use these regions (2a, 3a) as air discharge surfaces. If the combining portion (9) is formed by a combined single-layer texture, an air bag having further improved performance and capable of being manufactured at a lower cost can be obtained.
    • 轻便廉价的气囊具有改进的防回弹特性,通过以下步骤获得,该袋体具有气体发生器固定开口(4),通过组合(9)至少两片 (2,3),并且在袋体的外表面的预定部分上提供涂层(5,6,7,8),使得这些膜作为袋体加强构件和驱动保护构件两者起作用, 与没有设置涂膜的区域(2a,3a)适当地根据织布的透气性来适当地使用这些区域作为排气表面。 如果组合部分由组合的单层结构形成,则可以获得具有进一步改进的性能并能够以较低成本制造的气囊。
