Estimating the term…
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 interstices 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.
An air bag comprising an air bag fabric comprising a fabric material comprising a fibrous substrate and a covering layer made of a thermoplastic synthetic resin of less than 5 .mu.m in average thickness, said covering layer being adhered to a surface of the fibrous substrate such that interstices between the fibers are bridged by the thermoplastic synthetic resin covering layer and the thermoplastic synthetic resin is present in an amount of 0.05 to 20% based on the weight of the fibrous substrate.
An air bag comprising a plurality of fabric portions each comprising a fabric material, the fabric material of each said portion comprising a fibrous substrate and a covering layer made of a thermoplastic synthetic resin and being less than 5 .mu.m in average thickness, said covering layer being adhered to a surface of the fibrous substrate such that interstices between the fibers are bridged by the thermoplastic synthetic resin covering layer, at least one of said fabric portions providing a base fabric of the air bag and each of said fabric portions having stitches sewn at an external peripheral region thereof to secure the respective fabric portions in position in a desired configuration in the air bag and the thermoplastic synthetic resin is present in an amount of 0.05 to 20% based on the weight of the fibrous substrate.
