Beschreibung
Zusammenfassung:	A flame resistant fabric for the use in the construction of aviation airbags comprises a polyester fiber substrate which is treated with a first flame retardant. A polyurethane coating is applied to the polyester fiber substrate, which has been treated with the first flame retardant, to impart high pressure permeability resistance to the flame resistant fabric. The polyurethane coating comprises a second flame retardant to insure that the flame resistant fabric complies with Federal Aviation Requirement 25.853. The flame resistant fabric further comprises sufficient high pressure permeability resistance which is measured as a pressure of not less than about 198 kPa after five seconds from an initial inflation and pressurization to about 200 kPa, such as may be encountered in and during an inflation of aviation airbag assemblies.
