Abstract
Abstract A lifesaving support system comprising inflatible panels positioned on the seats, bulkheads and baggage racks of an airplane or the like. A gas system is provided for inflating the panels with carbon dioxide during takeoff and landing, the inflated panels cushion the shock and thereby protect the passengers in case of a crash or a violent landing.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
115 words
A lifesaving support system for use in a transportation vehicle having at least two seats, one being in front of the other, comprising an inflatable, expansible panel adapted to be positioned in said vehicle, a source of gas under a greater than atmospheric pressure, means connecting said source to the interior of said inflatable panel, controllable means for inflating said panel from said source and for deflating said panel, and valve means connected to the interior of said panel for venting the gas within said panel, said valve means being responsive to the deceleration of said transportation vehicle and opening to vent said gas when the deceleration of said transportation vehicle exceeds a predetermined limit.
Claim 2
Dependent Claim
115 words
A lifesaving support system for use in a transportation vehicle having at least two seats, one being in front of the other, comprising an inflatable, expansible panel adapted to be positioned in said vehicle, a source of gas under a greater than atmospheric pressure, means connecting said source to the interior of said inflatable panel, controllable means for inflating said panel from said source and for deflating said panel, and valve means connected to the interior of said panel for venting the gas within said panel, said valve means being responsive to the deceleration of said transportation vehicle and opening to vent said gas when the deceleration of said transportation vehicle exceeds a predetermined limit.
Claim 3
Dependent Claim
95 words
A lifesaving support system for use in a transportation vehicle having at least two seats, one being in front of the other, comprising: a plurality of inflatable, expansible panels adapted to be positioned at various locations in said vehicle, means for storing a gas under pressure, controllable means for delivering said gas from said storing means to the interior of each of said panels to inflate said panels and for pumping gas from said panels into said storing means, and control means positioned at a location remote from said panels for operating said controllable means.
Claim 4
Dependent Claim
95 words
A lifesaving support system for use in a transportation vehicle having at least two seats, one being in front of the other, comprising: a plurality of inflatable, expansible panels adapted to be positioned at various locations in said vehicle, means for storing a gas under pressure, controllable means for delivering said gas from said storing means to the interior of each of said panels to inflate said panels and for pumping gas from said panels into said storing means, and control means positioned at a location remote from said panels for operating said controllable means.
Claim 5
Dependent Claim
26 words
A lifesaving support system according to claim wherein said gas is carbon dioxide whereby when the panels are punctured the carbon dioxide provides retardation against fire.
Claim 6
Dependent Claim
17 words
A lifesaving support system according to claim 2 in which said controllable means comprises a reversible pump.
