Shock-absorbing air bag
First Claim
1. A shock-absorbing air bag comprising at least one high density woven fabric (A) composed of warps and wefts each consisting of a stretch-broken fasciated fiber yarn which comprises:
- (a) 0 to 90% by weight of thermoplastic synthetic fibers having a denier of 5 or less and a Young'"'"'s modulus of 1300 kg/mm2 or less; and
(b) 10 to 100% by weight of heat resistant organic fibers selected from the group consisting of wholly aromatic polyamide fibers, aramid-copolymer fibers, poly-p-phenylenesulfon fibers, poly-p-phenylenesulfide fibers, wholly aromatic polyester fibers, polyimide fibers, polyetheramide fibers and polyetheretherketone fibers, having a denier of 2 or less and a thermal decomposition temperature of 300°
C. or more, and evenly blended with the thermoplastic synthetic fibers (a).

Abstract
An shock-absorbing air bag for an automobile or aircraft, has a high heat and flame resistance and satisfactory mechanical strength and comprises a high density woven fabric composed of warps and wefts each comprising (a) 0 to 90% by weight of thermoplastic synthetic fibers, for example, polyester fibers, having a denier or 5 or less and a Young'"'"'s modulus of 1300 kg/mm2 or less, and (b) 10 to 100% by weight of heat resistant organic fibers, for example, aramid fibers, having a denier of 2 or less and a thermal decomposition temperature of 300° C. or more, the woven fabric preferably having a high cover factor of 1900 or more.
