Abstract

Airbag systems for protecting passengers during collision. The airbags are inflated with ambient air at atmospheric pressure in the vehicle cabin. In a preferred aspect, the airbags are interfaced with bladders which store the ambient air and which are compressed by an electromagnetic plate hurling process which compresses the bladder. The airbags can be deployed in any direction and protect the passengers in all places in the vehicle without the dangerous side effects of overpressure buildup.

Claims

1. An airbag system for protecting a passenger during collision, comprising:

an airbag which is inflatable with ambient air;

a bladder interfaced with the airbag for storing the ambient air before the collision;

a first means for storing energy which will be used to compress the bladder and thereby inflate the airbag; and

a plate interfaced to the first means which will be hurled against the bladder during a collision.

2. The system recited in claim 1 further comprising switch means interfaced to the first means for switching the energy to the plate, thereby causing the plate to force the ambient air from the bladder into the airbag.

3. The system recited in claim 2 wherein the first means is a capacitor.

10. The system recited in claim 1 wherein the energy delivery means is a coil.

11. The system recited in claim 10 wherein the bladder is housed in a seat in the vehicle.

12. The system recited in claim 10 wherein the bladder is housed in a door of the vehicle.

13. The system recited in claim 10 wherein the bladder is housed in a roof of the vehicle.

14. The system recited in claim 10 wherein the bladder is housed in a floor of the vehicle.

15. The system recited in claim 10 wherein an airbag is deployed in a rear direction.

16. The system recited in claim 10 wherein an airbag is deployed in a forward direction for lateral impact protection.

4. A system for inflating an airbag in a vehicle comprising:

energy storing means for storing energy which will be used to inflate the airbag;

gas storage means for storing gas to inflate the airbag;

compression means for compressing the gas storage means to cause the airbag to inflate;

an energy delivery means interfaced with the compression means for delivering the energy to the compression means, thereby causing the compression means to be hurled against the gas storage means.

5. The system recited in claim 4 wherein the energy storage means is a battery.

6. The system recited in claim 4 wherein the energy storage means is a spring.

7. The system recited in claim 4 wherein the energy storage means is a capacitor.

8. The system recited in claim 7 wherein the gas storage means is a bladder and the gas is ambient air.

9. The system recited in claim 8 wherein the compression means is a plate.
