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.
Claims19
A portable fire retardant wall for separating a space portion where a fire started from the remainder of an enclosed space, comprising foldable wall means made of a gas-tight, flame resistant material, inflatable ring hose means also made of a foldable, gas-tight, flame resistant material, said ring hose means being secured all around said foldable wall means for forming a frame around said foldable wall means when said ring hose means are inflated, means for inflating said ring hose means when said fire retardant wall is to be installed, and a portable base plate (12) substantially shorter than a width of said enclosed space, said ring hose means and said inflating means being permanently mounted to said portable base plate to form an easily storable unit that is transportable to any desired location within said enclosed space.
A system for separating a space where a fire has started in an aircraft cabin from the remainder of said aircraft cabin, comprising a plurality of stationary system portions secured at spaced intervals to said aircraft cabin inside thereof, and a portable system portion constructed for cooperation with any one of said stationary system portions when said portable system portion is to be deployed, each of said stationary system portions comprising first snap-fastener elements permanently installed at said spaced intervals, said portable system portion comprising foldable wall means made of a gas-tight, flame resistant material, inflatable ring hose means also made of a foldable, gas-tight, flame resistant material, said ring hose means being secured all around said foldable wall means for forming a frame around said foldable wall means when said ring hose means are inflated, portable means for inflating said ring hose means for installation, said portable system portion further comprising second snap-fastener elements permanently attached to a peripheral surface of said ring hose means in positions for cooperation with said first snap-fastener elements when said ring hose means are inflated for a rapid installation of said portable system portion.
