Abstract
Abstract An inflatable bag is located in a vehicle forwardly of an occupant. Solid propellant thrusters or thrusters powered by a stored or generated fluid are used for deploying the bag. Ambient air may be admitted into the bag during inflation, through either openings in the bag wall or openings in a vehicle wall to which the bag is secured. In either case the openings are provided with check valves for preventing or at least decreasing outward flow of the inflation fluid from the bag.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
151 words
Safety apparatus for a vehicle having a passenger compartment comprising an inflatable cushion located within the vehicle movable between a collapsed, inoperative position and an inflated, operative position for restraining an occupant of the vehicle during a collision; a flexible, inflatable, tubular framework operatively associated with said cushion and operable upon inflation to move said cushion to said operative position and causing inflation of said cushion by aspiration of air into said cushion during such movement, said framework including at least one opening into the interior of said cushion to provide inflating fluid supplemental to the air pumped into said cushion by aspiration during movement of said cushion to said operative position; a source of inflating fluid operatively associated with said framework for inflating said framework; and a collision sensor mounted on said vehicle for initiating fluid flow from said source to said framework upon the sensing of A vehicle collision.
Claim 2
Dependent Claim
151 words
Safety apparatus for a vehicle having a passenger compartment comprising an inflatable cushion located within the vehicle movable between a collapsed, inoperative position and an inflated, operative position for restraining an occupant of the vehicle during a collision; a flexible, inflatable, tubular framework operatively associated with said cushion and operable upon inflation to move said cushion to said operative position and causing inflation of said cushion by aspiration of air into said cushion during such movement, said framework including at least one opening into the interior of said cushion to provide inflating fluid supplemental to the air pumped into said cushion by aspiration during movement of said cushion to said operative position; a source of inflating fluid operatively associated with said framework for inflating said framework; and a collision sensor mounted on said vehicle for initiating fluid flow from said source to said framework upon the sensing of A vehicle collision.
Claim 3
Dependent Claim
110 words
Safety apparatus for a vehicle having a passenger compartment, said apparatus comprising: a. an inflatable cushion located within the vehicle and movable between a collapsed, inoperative position and an inflated, operative position, for restraining an occupant of the vehicle during a collision; b. a flexible, inflatable, tubular framework operatively associated with said cushion and operable upon inflation to move said cushion to said operative position, and c. said inflatable framework having openings facing inwardly into said cushion so that as inflating fluid flows into said inflatable framework, some of said fluid escapes through said openings into the cushion creating a reaction force for moving the cushion toward a distended condition.
Claim 4
Dependent Claim
110 words
Safety apparatus for a vehicle having a passenger compartment, said apparatus comprising: a. an inflatable cushion located within the vehicle and movable between a collapsed, inoperative position and an inflated, operative position, for restraining an occupant of the vehicle during a collision; b. a flexible, inflatable, tubular framework operatively associated with said cushion and operable upon inflation to move said cushion to said operative position, and c. said inflatable framework having openings facing inwardly into said cushion so that as inflating fluid flows into said inflatable framework, some of said fluid escapes through said openings into the cushion creating a reaction force for moving the cushion toward a distended condition.
Claim 5
Dependent Claim
55 words
The apparatus as recited in claim 2, further comprising means defining an inlet opening for aspiration of air into said cushion during movement to its operative position, so that movement of said cushion to its operative position draws aspirated air into said cushion, in addition to fluid discharged into said cushion from said inflatable framework.
