Abstract

A safety system including a substantially membrane-like panel which is deployable at least partially across a window opening of a transportation vehicle in a rapid manner from a position generally below the window opening. The panel provides a restraining barrier against undesired egress through the window opening during an extended rollover collision event. The panel may be used either alone or in combination with an inflatable air bag cushion.

Claims

1. A safety system for protection of an occupant within a transportation vehicle, the safety system comprising:

a panel of pliable material normally stored in a nonactivated storage position generally below a window opening adjacent to the occupant, the panel of pliable material being deployable upwardly away from the storage position at least partially across the window opening such that the panel of pliable material forms a restraining barrier at least partially across the window opening.

2. The invention as recited in

claim 1

, wherein the pliable material is a net structure comprising a plurality of crossing structural elements separated by interstitial voids.

3. The invention as recited in

claim 1

, wherein the panel is retractable to the storage position generally below the window opening subsequent to deployment.

4. The invention as recited in

claim 1

, wherein the panel is manually activatable upon demand by an occupant within the vehicle.

5. The invention as recited in

claim 1

, wherein the panel is substantially see through.

6. The invention as recited in

claim 5

, wherein the panel comprises a light interrupting grating such that the panel provides a see through shade against sunlight.

7. The invention as recited in

claim 1

, wherein the panel is deployable in a plane of deployment inboard of a window disposed at least partially across the window opening.

8. The invention as recited in

claim 7

, wherein the panel is deployable upwardly between the window and a sealing strip inboard of the window along the lower boundary of the window opening.

9. The invention as recited in

claim 1

, wherein the panel of pliable material is operatively connected to an arrangement of hoist lines extending away from the panel and wherein the operative length of the hoist lines is adjustable such that upon shortening the operative length of the hoist lines, the panel is raised away from its nonactivated storage position.

10. A safety system for protection of an occupant within a transportation vehicle, the safety system comprising:

a panel of pliable material normally stored in a nonactivated storage position generally below a window opening adjacent to the occupant, the panel of pliable material being deployable upwardly away from the storage position at least partially across the window opening, the safety system further comprising an inflatable air bag cushion deployable between the occupant and the panel of pliable material such that the panel of pliable material provides a backing support for the inflatable air bag cushion.

11. The invention as recited in

claim 10

, wherein the inflatable air bag cushion is deployable downwardly away from a storage position above the window opening.

12. The invention as recited in

claim 10

, wherein the pliable material is a net structure comprising a plurality of crossing structural elements separated by interstitial voids.

13. The invention as recited in

claim 10

, wherein the panel is retractable to the storage position generally below the window opening subsequent to deployment.

14. The invention as recited in

claim 10

, wherein the panel is manually activatable upon demand by an occupant within the vehicle prior to deployment of the inflatable air bag cushion.

15. The invention as recited in

claim 14

, wherein the panel is substantially see through.

16. The invention as recited in

claim 15

, wherein the panel comprises a light interrupting grating such that the panel provides a see through shade against sunlight prior to deployment of the inflatable air bag cushion.

17. The invention as recited in

claim 10

, wherein the panel is deployable upwardly between a moveable window within the window opening and a sealing strip inboard of the window, wherein the sealing strip extends along the lower boundary of the window opening.

18. The invention as recited in

claim 10

, wherein the panel of pliable material is operatively connected to an arrangement of hoist lines extending away from the panel and wherein the operative length of the hoist lines is adjustable such that upon shortening the operative length of the hoist lines, the panel is raised away from its nonactivated storage position.

19. A safety system for protection of an occupant within a transportation vehicle, the safety system comprising:

a panel of pliable material normally stored in a nonactivated storage position generally below a window opening adjacent to the occupant, the panel of pliable material being deployable upwardly away from the storage position at least partially across the window opening by a plurality of hoist lines extending away from the panel and over pulley guides disposed adjacent to lateral edges of the window opening, the hoist lines being operatively connected to length adjusting take up mechanisms disposed below the pulley guides to lengthen or shorten the operative length of the hoist lines such that upon shortening the operative length of the hoist lines the panel is raised into an operational position at least partially spanning the window opening.

20. The invention as recited in

claim 19

, wherein the length adjusting take up mechanisms comprise reversible take up rolls driven by a reversible motor.

21. The invention as recited in

claim 20

, further comprising a reversible storage roll supporting the panel at the storage position generally below the window opening, the reversible storage roll being operatively connected to the reversible take up rolls along a common spindle such that the reversible motor causes the substantially simultaneous rotation of the reversible storage roll and the reversible take up rolls.

22. The invention as recited in

claim 19

, further comprising an inflatable air bag cushion deployable between the occupant and the panel of pliable material such that the panel of pliable material provides a backing support for the inflatable air bag cushion.

23. The invention as recited in

claim 22

, wherein the inflatable air bag cushion is deployable downwardly away from a storage position above the window opening.
