Abstract
An air bag for vehicles is formed by a pair of sheets of composite materials for bags sewed together with a sewing thread at their peripheral portions which are inside the bag. A sewing thread protecting layer made of a rubber compound covers the exposed portions of the thread. Each of the sheets consists of a base fabric for bags and a heat-resistant film of a chloroprene rubber compound laminated on the inside surface of the base fabric. The sewing thread protecting layer is made of a rubber compound containing a blend polymer of ethylene propylene rubber and choroprene rubber with the blending formula by weight of the former and the latter being from 30/70 to 70/30.
