Abstract
Abstract A vehicle occupant restraint system having a plurality of bags which are inflated on vehicle impact with a stationary or moving object. One of the bags receives the impact of the occupant''s torso and on such impact, has controlled pressure relief to prevent excessive rebounding of the occupant. Another bag, that is located within the first-mentioned bag, receives the impact of the occupant''s legs and remains inflated on such impact to maintain the occupant in the normal seated position. Fluid delivery to pressurize both bags is delivered by a manifold which is continuously open to the outer bag and is connected by a oneway valve to the inner bag.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
163 words
In a vehicle occupant restraint system the combination of first inflatable bag means that on inflation by fluid pressure assumes a position to receive impact of a vehicle occupant''s torso; second inflatable bag means that is located within said first inflatable bag means and that on inflation by fluid pressure assumes a position to receive impact of the occupant''s legs through said first inflatable bag means to maintain the occupant in a seated position; fluid delivery means for delivering fluid under pressure simultaneously to said first and second inflatable bag means; said first inflatable bag means including pressure relief means for relieving pressure in said first inflatable bag means when said first inflatable bag means is impacted by the occupant''s torso; and said fluid delivery means including one-way valve means for delivering the fluid under pressure to said second inflatable bag means and maintaining the pressure in said second inflatable bag means while pressure is being relieved from said first inflatable bag means.
Claim 2
Dependent Claim
163 words
In a vehicle occupant restraint system the combination of first inflatable bag means that on inflation by fluid pressure assumes a position to receive impact of a vehicle occupant''s torso; second inflatable bag means that is located within said first inflatable bag means and that on inflation by fluid pressure assumes a position to receive impact of the occupant''s legs through said first inflatable bag means to maintain the occupant in a seated position; fluid delivery means for delivering fluid under pressure simultaneously to said first and second inflatable bag means; said first inflatable bag means including pressure relief means for relieving pressure in said first inflatable bag means when said first inflatable bag means is impacted by the occupant''s torso; and said fluid delivery means including one-way valve means for delivering the fluid under pressure to said second inflatable bag means and maintaining the pressure in said second inflatable bag means while pressure is being relieved from said first inflatable bag means.
Claim 3
Dependent Claim
122 words
The vehicle occupant restraint system set forth in claim 1 and said fluid delivery means comprising a manifold extending into said first inflatable bag means; first fluid delivery port means in said manifold open to the interior of said first inflatable bag means; second fluid delivery port means in said manifold; said one-way valve means mounted on said manifold interior of said first inflatable bag means and being operable to open said second fluid delivery port means to the interior of said second inflatable bag means for the fluid delivery to said second inflatable bag means and being operable to prevent fluid delivery from said second inflatable bag means to said manifold for the pressure maintenance in said second inflatable bag means.
Claim 4
Dependent Claim
95 words
A vehicle body occupant restraint system comprising, in combination, a source of pressure fluid, first inflatable cushion means engageable by the torso of a vehicle body occupant, second inflatable cushion means contained within the first cushion means and engageable therethrough by the legs of a vehicle body occupant, means communicating the first and second cushion means with the pressure fluid source for inflation thereof, means communicating the first cushion means with the atmosphere upon the pressure thereIn exceeding a predetermined level, and means maintaining the pressure fluid within the second cushion means upon inflation thereof.
Claim 5
Dependent Claim
95 words
A vehicle body occupant restraint system comprising, in combination, a source of pressure fluid, first inflatable cushion means engageable by the torso of a vehicle body occupant, second inflatable cushion means contained within the first cushion means and engageable therethrough by the legs of a vehicle body occupant, means communicating the first and second cushion means with the pressure fluid source for inflation thereof, means communicating the first cushion means with the atmosphere upon the pressure thereIn exceeding a predetermined level, and means maintaining the pressure fluid within the second cushion means upon inflation thereof.
