Abstract: A base fabric for non-coated air bags, in which both the warp and the weft or either of them comprise synthetic fiber multifilaments of flattened cross-section monofilaments having a degree of flatness of from 1.5 to 8.

Abstract: 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 &mgr;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.

The back roller is equipped with a positive easing mechanism, and the easing quantity by the easing mechanism is adjusted in a range from about 5 to about 15 mm. Where the warp yarns positioned in the selvages of the fabric among the warp yarns are called selvage yarns and the warp yarns additionally added to the selvage yarns are called insert yarns, then the number of insert yarns per 10 selvage yarns is in a range of from 1 to 10, and one selvage yarn each and one insert yarn each are guided through each dent of the reed.
