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.
