Airbag module on passenger door

1. An airbag module for a passenger door of an aircraft, comprising:

(a) a door bustle configured to store an aircraft escape slide, the door bustle comprising an inner surface and an outer surface comprising a breakable area;

(b) an airbag positioned adjacent the inner surface of the door bustle and the breakable area, wherein the breakable area is configured to allow the airbag to deploy through the outer surface; and

(c) an inflator coupled to the airbag and positioned adjacent the inner surface of the door bustle.

2. The airbag module of claim 1 , wherein the breakable area is pivotally coupled to a portion of the outer surface of the door bustle.

3. The airbag module of claim 1 , further comprising a stop positioned adjacent the breakable area and configured to prevent the breakable area from rotating forward past the stop.

4. The airbag module of claim 1 , wherein the door bustle further comprises a film that is positioned to cover at least the breakable area.

5. The airbag module of claim 1 , wherein the escape slide is positioned adjacent the inner surface of the door bustle and the airbag.

6. An airbag module for a passenger door comprising:

(a) a door bustle;

(b) an airbag positioned adjacent the door bustle;

(c) an inflator positioned adjacent the door bustle, wherein the inflator is configured to release a pressurized gas when activated; and

(d) a pneumatic system coupled to the inflator and the airbag, wherein the pneumatic system comprises a slide lock that is configured to couple a girt bar of an escape slide to a passenger door sill when the inflator is activated.

7. The airbag module of claim 6 , further comprising a valve that is coupled to an inlet of the airbag, wherein the valve is configured to prevent the pressurized gas from flowing from the inflator to the airbag when the valve is closed and is configured to allow the pressurized gas to flow from the inflator to the airbag when the valve is open.

8. The airbag module of claim 6 , wherein the escape slide is positioned adjacent the door bustle and coupled to the girt bar.

9. The airbag module of claim 6 , wherein the door bustle comprises an outer surface comprising a breakable area and the airbag is positioned adjacent the breakable area, wherein the breakable area is configured to allow the airbag to deploy through the outer surface.

10. The airbag module of claim 9 , wherein the breakable area is pivotally coupled to a portion of the outer surface of the door bustle.

11. The airbag module of claim 9 , further comprising a stop positioned adjacent the breakable area and configured to prevent the breakable area from rotating forward past the stop.

12. The airbag module of claim 9 , wherein the door bustle further comprises a film that is positioned to cover at least the breakable area.

13. A method of controlling an airbag module comprising (i) an airbag and (ii) an inflator, and a pneumatic system comprising a slide lock, wherein an outlet of the inflator is coupled to an inlet of the pneumatic system, an outlet of the pneumatic system is coupled to an inlet of a valve, and an outlet of the valve is coupled to an inlet of the airbag, the steps comprising:

detecting a signal from a sensing circuit;

determining that a crash has occurred;

transmitting a signal instructing the inflator to release pressurized gas; and

transmitting a signal instructing the valve to open.

14. The method of claim 13 , further comprising a switch that activates a control system connected to the inflator and the valve.

15. The method of claim 13 , further comprising the step of extending the slide lock to couple a girt bar of an escape slide to a passenger door sill.

16. The method of claim 15 , further comprising the step of deploying the airbag through a door bustle.

17. The method of claim 16 , further comprising the step of pivoting a breakable area away from an outer surface of the door bustle.

18. A method of controlling an airbag module comprising (i) an airbag and (ii) an inflator, and a pneumatic system comprising a slide lock, wherein an outlet of the inflator is coupled to an inlet of the pneumatic system, an outlet of the pneumatic system is coupled to an inlet of a valve, and an outlet of the valve is coupled to an inlet of the airbag, the steps comprising:

detecting a signal from a sensing circuit;

determining that a crash has not occurred;

detecting a signal from a door positioning sensor;

determining that a passenger door is being opened from within an interior of a vehicle;

transmitting a signal instructing the inflator to release pressurized gas; and

transmitting a signal instructing the valve to close.

19. The method of claim 18 , further comprising a switch that activates a control system connected to the inflator and the valve.

20. The method of claim 19 , further comprising the step of extending the slide lock to couple a girt bar of an escape slide to a passenger door sill.
