Apparatus, system and method for repositioning occupant in a crash event

1. An airbag system for repositioning a seat occupant in a moving vehicle during a potentially injurious event, the airbag system comprising:

a first inflatable airbag in a normally deflated state disposed proximate to a front portion of a seat pan;

a second inflatable airbag in the normally deflated state disposed proximate to a rear portion of the seat pan; and

an inflation control device controlling deployment of the first and second inflatable airbags, the inflation control device operatively communicative with the first and second inflatable airbags, the inflation control device comprising:

a programmable controller controlling inflation parameters of the first and second inflatable airbags to achieve a desired lift, subject to monument constraints; and

a plurality of inflation devices, each one configured to inflate each one of the first inflatable airbag and the second inflatable airbag, each of the plurality of inflation devices performing:

receiving a signal from a sensor device indicating detection of the potentially injurious event comprising an acceleration/deceleration above a pre-defined magnitude of force; and

responsive to receiving the signal, deploying its connected airbag to an inflated state, thereby repositioning the seat occupant by upwardly raising the seat occupant to a pre-specified height;

wherein the first and second inflatable airbags are deployed independently in a timed sequence with the second inflatable airbag being deployed before the first inflatable airbag, thereby lifting the seat occupant's torso before lifting the seat occupant's knees.

2. The airbag system of claim 1 wherein the first and second inflatable airbags are disposed between the seat pan and a seat cushion in direct contact with the seat occupant.

3. The airbag system of claim 1 wherein the first and second inflatable airbags are disposed between the seat pan and a seat frame.

4. The airbag system of claim 1 further comprising a mechanical lift operatively communicative with the inflation control device, the mechanical lift actuated by the inflation control device to exert an upwards force on the seat pan during the deployment of the first and second inflatable airbags.

5. The airbag system of claim 1 further comprising a bladder coupled with at least one of the first and second inflatable airbags to collect gaseous overflow upon deployment of the at least one of the first and second inflatable airbags.

6. The airbag system of claim 1 further comprising the sensor device operable to detect and measure vehicle acceleration and deceleration.

7. The airbag system of claim 1 wherein the programmable controller adjusts the timed sequence of deployment based on the monument constraints.

8. The airbag system of claim 1 wherein the first and second inflatable airbags are housed within a seat cushion, the seat cushion comprising:

a top surface in direct contact with the seat occupant; and

a bottom surface proximate to the seat pan.

9. An airbag system for repositioning a seat occupant in a moving vehicle during a potentially injurious event, the airbag system comprising:

a plurality of inflatable airbags in a normally deflated state disposed proximate to a seat pan; and

an inflation control device controlling deployment of the plurality of inflatable airbags, the inflation control device comprising:

a manifold having an inlet and a plurality of outlets, where each one of the plurality of outlets is connected to each one of the plurality of inflatable airbags;

a programmable controller controlling inflation parameters of each of the plurality of inflatable airbags to achieve a desired lift, subject to monument constraints; and

an inflation device connected to the inlet,

whereupon, the inflation control device receiving a signal from a sensor device indicating detection of the potentially injurious event comprising an acceleration/deceleration above a pre-defined magnitude of force; and

responsive to receiving the signal, activating the inflation device, thereby repositioning the seat occupant by upwardly raising the seat occupant to a pre-specified height;

wherein each of the plurality of inflatable airbags are deployed independently in a timed sequence configured by the manifold, thereby lifting the seat occupant's torso before lifting the seat occupant's knees.

10. The airbag system of claim 9 wherein the plurality of inflatable airbags are disposed between the seat pan and a seat cushion in direct contact with the seat occupant.

11. The airbag system of claim 9 wherein the plurality of inflatable airbags are disposed between the seat pan and a seat frame.

12. The airbag system of claim 9 further comprising a mechanical lift operatively communicative with the inflation control device, the mechanical lift actuated by the inflation control device to exert an upwards force on the seat pan during the deployment of the plurality of inflatable airbags.

13. The airbag system of claim 9 further comprising a bladder coupled with at least one of the plurality of inflatable airbags to collect gaseous overflow upon deployment of the at least one of the plurality of inflatable airbags.

14. The airbag system of claim 9 further comprising the sensor device operable to detect and measure vehicle acceleration and deceleration.

15. The airbag system of claim 9 wherein the programmable controller adjusts the timed sequence of deployment based on the monument constraints.

16. The airbag system of claim 9 wherein the plurality of inflatable airbags are housed within a seat cushion, the seat cushion comprising:

a top surface in direct contact with the seat occupant; and

a bottom surface proximate to the seat pan.
