A BASE FABRIC FOR AIR BAGS, A PROCESS FOR PRODUCING IT AND AN AIR BAG COMPRISING IT

摘要

A fabric for use as a base fabric in an air bag comprises a fibrous substrate having adhered to it a covering layer made of a thermoplastic synthetic resin and of 10 .mu.m or less in average thickness. The adhesion between the fibrous substrate and covering layer is effected by causing the thermoplastic synthetic resin material of the covering layer to fill intersteces between the fibers of the fibrous substrate. This may be achieved by applying to the fibrous substrate a solution or dispersion of the thermoplastic synthetic resin. An air bag may be constructed entirely from the fabric such that when it comprises sheet material additional to the base fabric, these may also be provided by the same fabric as that used for the base fabric.
