ABSTRACT:
A fire retardant separation wall for an aircraft cabin or transport space in an aircraft or in any other craft, is made portable by constructing such a separation wall as a foldable gas-tight wall made out of fire resistant material. A ring hose surrounds the entire separation wall. The ring hose has such a configuration that, when inflated, it will hug the inner contour of the aircraft cabin. The ring hose and, if used, reinforcing inflatable ribs, are inflated by a battery operated compressor so that the entire wall unit is portable and conveniently stored when deflated and folded. A pressurized gas container assures inflation even if a power failure should occur.
