Abstract

Embodiments of the present invention provide an airbag system formed of a plurality of tubular structures.

Claims

1. A tubular airbag system for use in a passenger transport vehicle, comprising:

(a) a plurality of inflatable tubular structures, each tubular structure having a length dimension that is greater than its width or height dimension, and comprising an opening at its end for receiving inflation gas;

the plurality of inflatable tubular structures comprising a first level comprising first and second side-by-side inflatable structures and a second level comprising a single inflatable structure having a conical cross section; and

(b) a system for securing the plurality of tubular structures to one another such that they deploy together.

2. The tubular airbag system of claim 1, further comprising a system for delivering inflation gas to the tubular airbag system.

3. The tubular airbag system of claim 1, wherein the system for securing the plurality of airbags to one another comprises a strap.

4. The tubular airbag system of claim 1, further comprising a system for attaching the tubular airbag system to an interior component of a vehicle.

5. The tubular airbag system of claim 4, wherein the system for attaching the tubular airbag system to an interior component of a vehicle comprises an inflation bag in fluid communication with one or more tubes extending from the inflation bag, wherein the one or tubes are in fluid communication with an inflation source.

6. The tubular airbag system of claim 1, further comprising a source of inflation gas in fluid communication with each tubular structure.

7. The tubular airbag system of claim 1, installed on a seat back of an aircraft seat, an aircraft monument, or an aircraft privacy shell.

8. The tubular airbag system of claim 1, installed in front of an aircraft seat at a securement location.

9. The tubular airbag system of claim 8, wherein a connection face of at least one of the inflatable structures comprises an angled connection face configured to compensate for an angle occurring between the securement location and the aircraft seat.

10. The tubular airbag system of claim 1, wherein the first and second side-by-side inflatable structures are in fluid communication with one another via a fluid passageway.

26. The tubular airbag system of claim 1, installed in front of an aircraft seat at a securement location.

27. The tubular airbag system of claim 26, wherein a connection face of at least one of the inflatable structures comprises an angled connection face configured to compensate for an angle occurring between the securement location and the aircraft seat.

11. A tubular airbag system for use in a passenger transport vehicle, comprising:

(a) a plurality of inflatable tubular structures, each tubular structure having a length dimension that is greater than its width or height dimension, and comprising an opening at its end for receiving inflation gas, each opening being in fluid communication with an inflation bag;

(b) wherein at least one of the inflation bag or the plurality of inflatable tubular structures comprise an angled connection face configured to be secured to a securement location in front of a passenger seat, wherein the angled connection face compensates for an angle occurring between the securement location and the passenger seat located therebehind.

12. The tubular airbag system of claim 11, further comprising a system for delivering inflation gas to the tubular airbag system.

13. The tubular airbag system of claim 11, further comprising a system for securing the plurality of airbags to one another comprising a strap.

14. The tubular airbag system of claim 11, further comprising a system for attaching the tubular airbag system to an interior component of a vehicle.

15. The tubular airbag system of claim 14, wherein the system for attaching the tubular airbag system to an interior component of a vehicle comprises an inflation bag in fluid communication with one or more tubes extending from the inflation bag, wherein the one or tubes are in fluid communication with an inflation source.

16. The tubular airbag system of claim 11, further comprising a source of inflation gas in fluid communication with each tubular structure.

17. The tubular airbag system of claim 11, installed on a seat back of an aircraft seat, an aircraft monument, or an aircraft privacy shell.

18. The tubular airbag system of claim 11, wherein the first and second side-by-side inflatable structures are in fluid communication with one another via a fluid passageway.

19. A tubular airbag system for use in a passenger transport vehicle, comprising:

(a) a plurality of inflatable tubular structures, each tubular structure having a length dimension that is greater than its width or height dimension, and comprising an opening at its end for receiving inflation gas;

(b) at least one fluid passageway along the length dimension of one or more of the plurality of inflatable tubular structures, allowing fluid communication therebetween.

20. The tubular airbag system of claim 19, further comprising a system for delivering inflation gas to the tubular airbag system.

21. The tubular airbag system of claim 19, further comprising a system for securing the plurality of airbags to one another comprising a strap.

22. The tubular airbag system of claim 19, further comprising a system for attaching the tubular airbag system to an interior component of a vehicle.

23. The tubular airbag system of claim 22, wherein the system for attaching the tubular airbag system to an interior component of a vehicle comprises an inflation bag in fluid communication with one or more tubes extending from the inflation bag, wherein the one or tubes are in fluid communication with an inflation source.

24. The tubular airbag system of claim 19, further comprising a source of inflation gas in fluid communication with each tubular structure.

25. The tubular airbag system of claim 19, installed on a seat back of an aircraft seat, an aircraft monument, or an aircraft privacy shell.
