Abstract
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 Analysis
Total Claims: 18
Claim 1
Independent Claim
69 words
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.
Claim 2
Dependent Claim
69 words
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.
Claim 3
Dependent Claim
37 words
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.
Claim 4
Dependent Claim
13 words
The system recited in claim 2 wherein the first means is a capacitor.
Claim 5
Independent Claim
78 words
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.
Claim 6
Independent Claim
78 words
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.
Claim 7
Dependent Claim
14 words
The system recited in claim 4 wherein the energy storage means is a battery.
Claim 8
Dependent Claim
14 words
The system recited in claim 4 wherein the energy storage means is a spring.
Claim 9
Dependent Claim
14 words
The system recited in claim 4 wherein the energy storage means is a capacitor.
Claim 10
Dependent Claim
20 words
The system recited in claim 7 wherein the gas storage means is a bladder and the gas is ambient air.
Claim 11
Dependent Claim
13 words
The system recited in claim 8 wherein the compression means is a plate.
Claim 12
Dependent Claim
14 words
The system recited in claim 1 wherein the energy delivery means is a coil.
Claim 13
Dependent Claim
17 words
The system recited in claim 10 wherein the bladder is housed in a seat in the vehicle.
Claim 14
Dependent Claim
17 words
The system recited in claim 10 wherein the bladder is housed in a door of the vehicle.
Claim 15
Dependent Claim
17 words
The system recited in claim 10 wherein the bladder is housed in a roof of the vehicle.
Claim 16
Dependent Claim
17 words
The system recited in claim 10 wherein the bladder is housed in a floor of the vehicle.
Claim 17
Dependent Claim
15 words
The system recited in claim 10 wherein an airbag is deployed in a rear direction.
Claim 18
Dependent Claim
19 words
The system recited in claim 10 wherein an airbag is deployed in a forward direction for lateral impact protection.
