Abstract: A tube suitable for use in a vehicular airbag comprises a seamless tube of integral, unitary, one-piece woven construction. The tube defines a pair of opposed panels of substantial area formed in a plain weave of a first yarn density. A pair of intermediate margins of slight width joins an opposed pair of sides of the opposed panels together, the intermediate margins being formed in a plain interweave of a second yarn density greater than the first yarn density. A pair of outer margins is provided, each of substantially greater width than one of the intermediate margins and extending about the outer side of a respective one of the intermediate margins, the outer margins being formed in a weave looser than the plain interweave. The airbag is made by joining a second opposed pair of sides of the opposed panels together to form a bag, inverting the bag and positioning inflation means in gaseous communication with the interior of the inverted bag for inflating the inverted bag.

Abstract: A bag suitable for use in a vehicular airbag comprises a seamless bag of integral, unitary, one-piece woven construction. The bag defines a pair of opposed panels of substantial area formed in a plain weave of a first yarn density. A single intermediate margin of slight width joins the peripheries of the opposed panels together, the intermediate margin being formed in a plain interweave of a second yarn density greater than the first yarn density. A single outer margin of substantially greater width than the intermediate margin extends about the periphery of the intermediate margin, the outer margin being formed in a weave looser than the plain interweave. The airbag is made by inverting the bag and positioning inflation means in gaseous communication with the interior of the inverted bag for inflating the inverted bag.
