Total Claims: 8
Claim 1
Independent Claim
131 words
In an automotive vehicle, the combination comprising, an inflatable occupant restraint mounted within an occupant compartment of the vehicle, a bumper impact bar, energy absorbing means supporting the impact bar on the vehicle and including a piston movable within a chamber containing a gas liquefied under pressure and ambient temperature, means controlling the displacement of the liquefied gas from one side of the piston to the other side of the piston upon impact of the impact bar with an obstacle to absorb the energy of the resultant impact forces, and means responsive to the displacement of a predetermined volume of liquefied gas to the other side of the piston for communicating the chamber and the restraint to release the liquefied gas for expansion and flow to the restraint for inflation thereof.
Claim 2
Dependent Claim
131 words
In an automotive vehicle, the combination comprising, an inflatable occupant restraint mounted within an occupant compartment of the vehicle, a bumper impact bar, energy absorbing means supporting the impact bar on the vehicle and including a piston movable within a chamber containing a gas liquefied under pressure and ambient temperature, means controlling the displacement of the liquefied gas from one side of the piston to the other side of the piston upon impact of the impact bar with an obstacle to absorb the energy of the resultant impact forces, and means responsive to the displacement of a predetermined volume of liquefied gas to the other side of the piston for communicating the chamber and the restraint to release the liquefied gas for expansion and flow to the restraint for inflation thereof.
Claim 3
Dependent Claim
149 words
In an automotive vehicle, the combination comprising, an inflatable occupant restraint mounted within an occupant compartment of the vehicle, a bumper impact bar, energy absorbing means supporting the impact bar on the vehicle and including a piston movable within a chamber containing a gas liquefied under pressure and ambient temperature, means controlling the displacement of the liQuefied gas from one side of the piston to the other side of the piston upon impact of the impact bar with an obstacle to absorb the energy of the resultant impact forces, means including normally closed valve means for communicating the chamber and the restraint, and means responsive to the displacement of a predetermned volume of liquefied gas to the other side of the piston for opening the valve means and communicating the chamber and the restraint to release the liquefied gas for expansion and flow to the restraint for inflation thereof.
Claim 4
Dependent Claim
149 words
In an automotive vehicle, the combination comprising, an inflatable occupant restraint mounted within an occupant compartment of the vehicle, a bumper impact bar, energy absorbing means supporting the impact bar on the vehicle and including a piston movable within a chamber containing a gas liquefied under pressure and ambient temperature, means controlling the displacement of the liQuefied gas from one side of the piston to the other side of the piston upon impact of the impact bar with an obstacle to absorb the energy of the resultant impact forces, means including normally closed valve means for communicating the chamber and the restraint, and means responsive to the displacement of a predetermned volume of liquefied gas to the other side of the piston for opening the valve means and communicating the chamber and the restraint to release the liquefied gas for expansion and flow to the restraint for inflation thereof.
Claim 5
Dependent Claim
169 words
In an automotive vehicle, the combination comprising, an inflatable occupant restraint mounted within an occupant compartment of the vehicle, a bumper impact bar, energy absorbing means supporting the impact bar on the vehicle and including an apertured piston movable within a chamber containing a gas liquefied under pressure and ambient temperature, means including resiliently seated valve means communicating the chamber and the restraint, control means on the valve means received within the piston aperture to control the displacement of the liquefied gas through the piston aperture from one side of the piston to the other side of the piston upon impact of the impact bar with an obstacle to absorb the energy of the resultant impact forces, and means operative upon the displacement of a predetermined volume of liquefied gas to the other side of the piston for engaging the control means to unseat the valve means and communicate the chamber and the restraint and release the liquefied gas for expansion and flow to the restraint for inflation thereof.
Claim 6
Dependent Claim
169 words
In an automotive vehicle, the combination comprising, an inflatable occupant restraint mounted within an occupant compartment of the vehicle, a bumper impact bar, energy absorbing means supporting the impact bar on the vehicle and including an apertured piston movable within a chamber containing a gas liquefied under pressure and ambient temperature, means including resiliently seated valve means communicating the chamber and the restraint, control means on the valve means received within the piston aperture to control the displacement of the liquefied gas through the piston aperture from one side of the piston to the other side of the piston upon impact of the impact bar with an obstacle to absorb the energy of the resultant impact forces, and means operative upon the displacement of a predetermined volume of liquefied gas to the other side of the piston for engaging the control means to unseat the valve means and communicate the chamber and the restraint and release the liquefied gas for expansion and flow to the restraint for inflation thereof.
Claim 7
Dependent Claim
169 words
In an automotive vehicle, the combination comprising, an inflatable occupant restraint mounted within an occupant compartment of the vehicle, a bumper impact bar, energy absorbing means supporting the impact bar on the vehicle and including an apertured piston movable within a chamber containing a gas liquefied under pressure and ambient temperature, valve means on the chamber including a resiliently seated valve member and a metering member projecting therefrom through the piston aperture, the metering member controlling the displacement of the liquefied gas from one side of the piston to the other side of the piston upon impact of the impact bar with an obstacle to absorb the energy of the resultant impact forces, means operable upon the displacement of a predetermined volume of liquefied gas to the other side of the piston for engaging the metering member and unseating the valve means, and means communicating the valve means and the restraint to conduct the liquefied gas from the chamber for expansion and flkow to the restraint for inflation thereof.
