Abstract
An inflatable safety balloon made of a flexible material is folded and mounted within a compartment on an elastic attachment cord which is mounted inside of a car in a manner resembling a shoulder harness so as to position the compartment in front of a wearer'"'"''"'"'s chest. A gas release mechanism and a source of pressurized gas which inflates the balloon in an area between a wearer'"'"''"'"'s chest and the dashboard or front seat when activated. The gas release mechanism may be inertially activated or manually activated.

1. A system for preventing injuries to the occupants of a vehicle upon severe deceleration thereof, said system consisting of an inflatable balloon pack, an inflating hose connected to said pack, a pneumatic pressure means remote from said pack and connected to the other end of said inflating hose for inflating said balloon upon severe deceleration of said vehicle once armed, and balloon support means attachable to said vehicle at at least two points for positioning said balloon pack across the chest of an occupant of said vehicle, said pneumatic pressure means being armed by placing said balloon support means across the chest of said occupant.
-
2. A system as in claim 1 wherein said pneumatic pressure means comprises an inertial weight means and a gas storage means, said inertial weight means adapted to effect the release of gas from said gas storage means upon severe deceleration of said vehicle to inflate said balloon.
-
3. A system as in claim 2 wherein said gas storage means is sealed by a rupturable diaphragm and said inertial weight means is adapted to slide and puncture said diaphragm upon severe deceleration.
-
4. A system as in claim 3 wherein said inertial weight is normally biased against movement by a spring, said biasing being of a force sufficient to prevent sliding movement of said weight upon ordinary vehicle deceleration but not sufficient to prevent such movement upon severe deceleration.
-
5. A system as in claim 2 wherein a safety pin is provided to prevent said inertial weight means from accidentally or when undesired effecting release of Said gas means, said pin connected to said balloon support means so that attachment of said support means arms said pneumatic pressure means.
-
6. A system as in claim 1 wherein said pneumatic means is adapted to be positioned on the floorpan or seat of said vehicle.
-
7. A system as in claim 1 wherein said pneumatic means is adapted to be positioned on the firewall of said vehicle.
-
8. A system as in claim 1 wherein said balloon support means is an elastic strap at least one end of which is adapted to be attached to the top or side of the inside of the vehicle.
-
9. A system as in claim 8 wherein said pneumatic pressure means comprises an inertial weight means and a gas storage means, said inertial weight means adapted to effect the release of gas from said gas storage means upon severe deceleration of said vehicle to inflate said balloon, a safety pin means normally biased into a position to prevent said inertial weight means from effecting release of said gas, said pin means being operatively connected to said elastic strap means so that attachment of said elastic strap means arms said pneumatic pressure means by repositioning said pin means.
-
10. A system as in claim 8 wherein said balloon pack is slidably mounted on said elastic strap means.
-
11. A system as in claim 1 wherein said balloon support means is a nonelastic shoulder harness and is adapted to be attached to the top or side of the inside of a vehicle and the other end is adapted to be secured to a lap belt.
-
12. A system as in claim 11 wherein said pneumatic pressure means comprises an inertial weight means and a gas storage means, said inertial weight means adapted to effect the release of gas from said storage means upon severe deceleration of said vehicle to inflate said balloon, a safety pin means normally biased into a position to prevent said inertial weight means from effecting release of said gas, said pin means being operatively connected to said balloon pack so that deployment of said balloon pack arms said pneumatic pressure means by repositioning said pin means.
-
13. A system as in claim 11 wherein said balloon pack is slidably mounted on said shoulder harness.
-
14. A system as in claim 1 wherein said balloon support means comprises a two section elastic strap means connected together by a buckle, the other ends of said strap means being adapted to be attached to the top and bottom of the inside structure of said vehicle respectively.
-
15. A system as in claim 14 wherein said pneumatic pressure means comprises an inertial weight means and a gas storage means, said inertial weight means adapted to effect the release of gas from said gas storage means upon severe deceleration of said vehicle to inflate said balloon, a safety pin means normally biased into a position to prevent said inertial weight means from effecting release of said gas, said pin means being operatively connected to said elastic strap means so that deployment of said elastic strap means arms said pneumatic means.
-
16. A system as in claim 14 wherein said pneumatic pressure means comprises an inertial weight means and a gas storage means, said inertial weight means adapted to effect the release of gas from said gas storage means upon severe deceleration of said vehicle to inflate said balloon, a safety pin means normally biased into a position to prevent said inertial weight means from effecting release of said gas, said pin means being operatively connected to said elastic strap means so that deployment of said elastic strap means repositions said pin means and arms said pneumatic means.
-
17. In combination with a vehicle having at least a front seat, a roof with accompanying upper structure and floor, a system for perventing injuries to the occupants of said vehicle, said system comprising an inflatable balloon pack, a balloon support means attachable to at least two points on said vehicle for positioning said balloon pack on the chest of an occupant of said vehicle, a pneumatic pressure means mounted on said vehicle for inflating said balloon upon severe deceleration of said vehicle once armed, and an inflating hose connecting said pneumatic pressure means with said balloon, said pneumatic pressure means being armed by placing said balloon support means across the chest of said occupant.
-
18. A combination as in claim 17 wherein said balloon support means comprises an elastic strap at least one end of which is secured to the upper structure of said vehicle.
-
