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.

Abstract: An aircraft inflatable harness assembly for an aircraft oxygen crew mask for providing regulated flow of oxygen on board an aircraft for an aircraft crew. The aircraft inflatable harness includes at least one inner inflatable tube having a normally deflated configuration and an inflated configuration. The inner inflatable tube has a first and second end, and is configured to inflate to cause expansion of the harness assembly to allow the harness assembly to be placed over a user's head. The inner inflatable tube includes a braided outer sleeve of elastic material. The outer sleeve is configured to have a first length when the inner inflatable tube is in a normally deflated configuration, and the outer sleeve is configured to longitudinally expand to a second length greater than the first length while remaining appreciably the same diameter in the radial direction when the inner inflatable tube is in an inflated configuration.
