Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 143 words
In an automotive vehicle cabin having an inflatable bag operable to inflate within the cabin providing a soft bumper and passenger motion restraint responsive to a preselected threshhold of deacceleration of the automotive vehicle, the improvements comprising: a tube for conducting gas to the inflatable bag; the inflatable bag being wrapped around said tube prior to inflation; said tube having apertures for conducting gas from inside the tube to the bag; a plug preventing passage of gas through the tube operable to slide through the interior of the tube, allowing passage of gas through the tube; said plug having a hollow portion for conducting gas from aft of the plug to immediately aft of the forward face of the plug and to said bag in an amount and rate substantially less than gas being fed to the bag immediately aft of the plug.
Claim 2
Dependent Claim 143 words
In an automotive vehicle cabin having an inflatable bag operable to inflate within the cabin providing a soft bumper and passenger motion restraint responsive to a preselected threshhold of deacceleration of the automotive vehicle, the improvements comprising: a tube for conducting gas to the inflatable bag; the inflatable bag being wrapped around said tube prior to inflation; said tube having apertures for conducting gas from inside the tube to the bag; a plug preventing passage of gas through the tube operable to slide through the interior of the tube, allowing passage of gas through the tube; said plug having a hollow portion for conducting gas from aft of the plug to immediately aft of the forward face of the plug and to said bag in an amount and rate substantially less than gas being fed to the bag immediately aft of the plug.
Claim 3
Dependent Claim 45 words
The apparatus of claim 1 wherein said hollow portion comprises an aft interior chamber communicating with a forward interior chamber and a plurality of apertures leading from said interior forward chamber of the plug to the exterior of the plug and interior of said tube.
Claim 4
Dependent Claim 91 words
The apparatus of claim 2 wherein said plug has a forward portion with an exterior right circular cylindrical shape coaxial and flush with the interior surface of said tube and an aft portion with an external right circular cylindrical surface co-axial with and flush with said tube and a middle portion having an exterior surface connecting and integral with said forward and aft portions having a narrowed shank external surface defining a chamber external to the plug but interior to the tube between said forward and aft sections of the plug.
Claim 5
Dependent Claim 32 words
The apparatus of claim 3 wherein said forward interior chamber is within said forward section and said aft interior chamber passes through said aft portion and said middle portion of said plug.
Claim 6
Dependent Claim 38 words
The apparatus of claim 4 wherein said apertures leading from said forward portion of said plug to externally of the plug are in radially array about the central axis of all of the right circular cylindrical configurations aforementioned.
Claim 7
Dependent Claim 44 words
The apparatus of claim 1 wherein said tube has a plurality of apertures longitudinally and radially dispersed about the central axis of said tube and said bag being tightly wrapped about said tube and operable to be inflated through said plurality of said apertures.
Claim 8
Dependent Claim 30 words
The apparatus of claim 1 and means for forcing said plug through said tube by expanding gas behind the plug responsive to movement of a mechanical member about an axis.
Claim 9
Dependent Claim 31 words
The apparatus of claim 7 wherein said mechanical member is biased against rotation and has an additional limit against translation that is rendered inoperable responsive to a predetermined threshold of force.
Claim 10
Dependent Claim 22 words
The apparatus of claim 1 and means for venting said cabin responsive to a predetermined threshold of air pressure within said cabin.
