Abstract
Abstract A fabric for use in an air bag is provided. The fabric of the invention is produced by mechanically compressing a preliminary fabric constructed substantially of synthetic yarn such that the packed volume per unit area of the compressed fabric is less than the packed volume per unit area of the preliminary fabric. Air permeability is not adversely affected.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
97 words
A woven fabric for manufacture of an air bag, comprising the (a) a preliminary woven fabric constructed substantially of synthetic yarns wherein the preliminary woven fabric has a reference packaged volume per unit area and a reference dynamic air permeability; and after processing (b) compressed fabric having a mass per unit area at least 4 percent greater than the mass per unit area of the preliminary woven fabric and wherein both the packed volume per unit area and the dynamic air permeability of the compressed fabric are less than the reference values of the preliminary woven fabric.
Claim 2
Dependent Claim
97 words
A woven fabric for manufacture of an air bag, comprising the (a) a preliminary woven fabric constructed substantially of synthetic yarns wherein the preliminary woven fabric has a reference packaged volume per unit area and a reference dynamic air permeability; and after processing (b) compressed fabric having a mass per unit area at least 4 percent greater than the mass per unit area of the preliminary woven fabric and wherein both the packed volume per unit area and the dynamic air permeability of the compressed fabric are less than the reference values of the preliminary woven fabric.
Claim 3
Dependent Claim
36 words
The invention as in claim 1 , wherein step (b), the packed volume per unit area is at least about 8 percent less than the reference packed volume per unit area of the preliminary woven fabric.
Claim 4
Dependent Claim
13 words
An air bag made of the woven fabric according to claim 2 .
Claim 5
Dependent Claim
12 words
