Abstract
The inflatable harness assembly for an aircraft oxygen crew mask includes one or more inflatable tubes having an outer layer of fabric material with an airtight coating for inflating the inflatable harness assembly. The inflatable tubes include an inner core of resilient, elastic material fixedly connected between first and second ends of the inflatable tubes that biases the inflatable tubes to shorten when the tubes are deflated. Inflation of the tubes them to expand the outer layer of material radially outwardly and lengthen axially, to allow the harness assembly to be placed over the user's head. Deflation of the tubes causes the aircraft inflatable harness assembly to grip the user's head with a desired head tension.
