Bag, airbag, and method of making the same
First Claim
1. A bag suitable for use in an airbag comprising:
- a seamless bag of integral, unitary, one-piece woven construction, said bag defining;
(i) a pair of opposed panels of substantial area formed in a plain weave of a first yarn density;
(ii) a single intermediate margin of slight width joining the peripheries of said opposed panels together, said intermediate margin being formed in a plain interweave of a second yarn density greater than said first yarn density; and
(iii) a single outer margin of substantially greater width than said intermediate margin extending about the periphery of said intermediate margin, said outer margin being formed in a weave looser than said plain interweave.

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.

13. A bag suitable for use in an airbag, comprising:
a seamless bag of integral, unitary, one-piece woven construction, devoid of any sewing or stitching and having a Frazier porosity of less than 8 cubic feet per minute, said bag defining; (i) a pair of opposed panels of substantial area formed in a plain weave of a first weave of about 45×
45, each of said opposed panels being of substantially rectangular configuration,(ii) a single intermediate margin having a total of about 4 picks and 4 ends and a width of about 2.0 mm. joining the peripheries of said opposed panels together, said intermediate margin being formed in a plain interweave of about 90×
90, and(iii) a single outer margin having a width of about 6.0 mm extending about the periphery of said intermediate margin, said outer margin being formed in a non-plain single/triple weave of about 90×
90 looser than said plain interweave.

14. An airbag comprising:
-
(A) an inverted seamless bag of integral, unitary, one-piece woven construction having a Frazier porosity of less than 8 cubic feet per minute, said bag prior to inversion defining; (i) a pair of opposed panels of substantial area formed in a plain weave of a first count, (ii) a single intermediate margin of slight width joining the peripheries of said opposed panels together, said intermediate margin being formed in a plain interweave of a second count greater than said first count; and (iii) a single outer margin of substantially greater width than said intermediate margin extending about the periphery of said intermediate margin, said outer margin being formed in a weave looser than said plain interweave; and (B) inflation means in gaseous communication with the interior of said inverted bag for inflating said inverted bag. - View Dependent Claims (15, 16)

17. A method of making a bag for an airbag, comprising the steps of:
(A) weaving a seamless bag of integral, unitary, onepiece woven construction having a Frazier porosity of less than 8 cubic feet per minute, said bag defining; (i) a pair of opposed panels of substantial area formed in a plain weave of a first yarn density; and (ii) a single intermediate margin of slight width joining of the periphery of said opposed panels together, said intermediate margin being formed in a plain weave of a second yarn density greater than said first yarn density; and (iii) a single outer margin of substantially greater width than said intermediate margin extending about the periphery of said intermediate margin, said outer margin being formed in a weave looser than said plain weave. - View Dependent Claims (18, 19)
