Abstract

A restraint system for a seat is provided and may include a first portion formed from a first material and having a first end fixed for movement with the seat and a second end movable relative to the seat. A second portion may be integral with or attached to the first portion, may be formed from the first material, and may be operable between a pre-deployed state and an inflated state.

Claims

1. A restraint system for a seat, the restraint system comprising:

a first portion formed from a first material and including a first end fixed for movement with the seat and a second end attached to one of a buckle and a tongue and movable relative to the seat, said first portion including at least three segments extending along an entire length of said first portion between said first end and said second end formed by folding said first material along at least two fold lines that extend substantially parallel to a longitudinal axis of said first portion; and

a second portion attached to one of said at least three segments of said first portion and formed from said first material, said second portion operable between a pre-deployed state and an inflated state.

2. The restraint system of claim 1, wherein said first portion and said second portion are integrally formed from a same piece of said first material.

3. The restraint system of claim 2, wherein said first portion and said second portion include different weave patterns.

4. The restraint system of claim 1, wherein said first material is one of a cut-and-sewn airbag-cushion material, a one-piece woven airbag-cushion material, or a laminate airbag-cushion material.

5. The restraint system of claim 1, wherein said first end is attached to an anchor to fix said first end for movement with the seat and said one of said buckle and said tongue is in selective engagement with an other of said buckle and said tongue.

6. The restraint system of claim 5, wherein said other of said buckle and said tongue is attached to the seat by seatbelt webbing or airbag-cushion material.

7. The restraint system of claim 1, wherein said first material remains folded when said second portion is in said inflated state.

8. The restraint system of claim 1, further comprising a manifold in fluid communication with said second portion and operable to selectively deliver pressurized gas to said second portion to move said second portion from said pre-deployed state to said inflated state.

9. The restraint system of claim 8, wherein said manifold is flexible to permit movement of said first portion and said second portion relative to the seat when said second portion is in said pre-deployed state.

10. The restraint system of claim 8, wherein said manifold is received within a pocket of said second portion, said pocket including at least one passageway that communicates said pressurized gas from said manifold to an interior of said second portion to move said second portion from said pre-deployed state to said inflated state.

11. The restraint system of claim 10, wherein said at least one passageway is closed prior to movement of said second portion into said inflated state.

12. The restraint system of claim 8, wherein said first portion is in fluid communication with said manifold.

13. The restraint system of claim 1, further comprising at least one tether associated with said second portion that controls a trajectory of said second portion when said second portion is moved from said pre-deployed state to said inflated state.

14. The restraint system of claim 13, wherein said at least one tether is integrally formed with one of the first portion or the second portion.

15. In a restraint system for a seat, a seatbelt includes a first belt segment, a second belt segment, and a latch mechanism that selectively couples said first belt segment to said second belt segment to restrain an occupant in the seat, said first belt segment or said second belt segment being formed from an airbag-cushion material that includes a first portion attached at a first location to an anchor and at a second location to said latch mechanism and a second portion selectively movable from a pre-deployed state to an inflated state, said first portion including at least three segments extending along an entire length of said first portion between said first location and said second location and formed by folding said airbag-cushion material along at least two fold lines that extend substantially parallel to a longitudinal axis of said first portion.

16. The seatbelt of claim 15, wherein said first portion and said second portion are integrally formed from a same piece of said airbag-cushion material.

17. The seatbelt of claim 15, wherein said airbag-cushion material is one of a cut-and-sewn material, a one-piece woven material, or a laminate material.

18. The seatbelt of claim 15, wherein said first portion and said second portion are formed from different airbag-cushion materials.

19. The seatbelt of claim 18, wherein said first portion and said second portion include different weave patterns.

20. The seatbelt of claim 15, wherein said first portion and said second portion include different weave patterns.

21. The seatbelt of claim 15, wherein said airbag-cushion material remains folded when said second portion is in said inflated state.

22. The seatbelt of claim 15, wherein said latch mechanism includes a buckle associated with one of said first belt segment and said second belt segment and a tongue associated with an other of said first belt segment and said second belt segment.

23. The seatbelt of claim 22, wherein said first portion is attached to said tongue.

24. The seatbelt of claim 15, further comprising a manifold in fluid communication with said second portion and operable to selectively deliver pressurized gas to said second portion to move said second portion from said pre-deployed state to said inflated state.

25. The seatbelt of claim 24, wherein said manifold is flexible to permit movement of said first portion and said second portion relative to the seat when said second portion is in said pre-deployed state.

26. The seatbelt of claim 24, wherein said manifold is received within a pocket of said second portion, said pocket including at least one passageway that communicates said pressurized gas from said manifold to an interior of said second portion to move said second portion from said pre-deployed state to said inflated state.

27. The seatbelt of claim 26, wherein said at least one passageway is closed prior to movement of said second portion into said inflated state.

28. The seatbelt of claim 24, wherein said first portion is in fluid communication with said manifold.

29. The seatbelt of claim 15, further comprising at least one tether associated with said second portion that controls a trajectory of said second portion when said second portion is moved from said pre-deployed state to said inflated state.
