Abstract

A module comprising a packaged airbag, wherein the airbag is configured to deploy on an interior side of a vehicle in a curtain arrangement; wherein the airbag is packaged so that the bottom of the airbag is folded then rolled in an outboard direction; and wherein the packaged airbag includes a folded portion located above the outboard rolled portion; and wherein the top portion is folded along a longitudinally extending crease to create a folded section located adjacent and outboard the rolled and folded sections. A module further comprising a Z-shaped folded portion above the outboard rolled portion, a second fold of the bottom portion in the outboard direction, a Z-shaped fold located between the bottom and top portions of the airbag, an inflator system, a plurality of mounting straps, and at least one tether on each of the fore and aft ends of the module.

Claims

1. A module comprising a packaged airbag, wherein the airbag is configured to deploy on an interior side of a vehicle in a curtain arrangement;

wherein the airbag is packaged so that a bottom portion of the airbag is folded then rolled in an outboard direction to form an outboard rolled portion; and

wherein the packaged airbag includes a folded portion located above the outboard rolled portion; and

wherein a top portion of the airbag is folded along a longitudinally extending crease to create a folded section located adjacent and outboard the rolled and folded portions.

2. A module of claim 1, wherein the folded portion is Z-shaped.

3. A module of claim 1, further comprising a second fold of the bottom portion of the airbag in the outboard direction.

4. A module of claim 1, further comprising a Z-shaped fold located between the bottom and top portions of the airbag.

5. A module of claim 1, further comprising an inflator system to provide the gas for expanding the airbag.

6. A module of claim 1, further comprising a plurality of mounting straps to provide a method of attaching the module to a vehicle.

7. A module of claim 1, further comprising at least one tether on each of the fore and aft ends of the module to provide stability during deployment of the airbag.

8. A module of claim 1, wherein the airbag includes a first portion located aft of a vehicle B-pillar and a second portion located forward of the B-pillar;

and wherein the top portion only of the second portion of the airbag is folded along a longitudinally extending crease to create a folded section located adjacent and outboard the rolled and folded portions.

9. A module comprising a packaged airbag, wherein the airbag is configured to deploy on an interior side of a vehicle in a curtain arrangement;

wherein the airbag has a first portion located aft of a vehicle B-pillar and a second portion located forward of the B-pillar;

wherein the first portion is packaged so that a bottom portion of the first portion of the airbag is folded then rolled in an outboard direction to form an outboard rolled portion of the first portion, and wherein the packaged first portion of the airbag includes a folded portion located above the outboard rolled portion of the first portion; and

wherein the second portion is packaged so that a bottom portion of the second portion of the airbag is folded and then rolled in an outboard direction to form an outboard rolled portion of the second portion and wherein the packaged second portion of the airbag includes a folded portion located above the outboard rolled portion of the second portion; and

wherein a top portion of the second portion of the airbag is folded along a longitudinally extending crease to create a folded section located adjacent and outboard the folded and rolled portions of the second portion.

10. A module of claim 9, wherein the folded portion above the outboard rolled portion of the first portion of the airbag includes a Z-shaped fold.

11. A module of claim 9, wherein the folded portion above the outboard rolled portion of the second portion of the airbag includes a Z-shaped fold.

12. A module of claim 9, further comprising a second fold of the bottom portion of the first portion of the airbag in the outboard direction.

13. A module of claim 9, further comprising a Z-shaped fold located between the bottom and top portions of the airbag.

14. A module of claim 9, further comprising an inflator system to provide the gas for expanding the airbag.

15. A module of claim 9, further comprising a plurality of mounting straps to provide a method of attaching the module to a vehicle.

16. A module of claim 9, further comprising at least one tether on each of the fore and aft ends of the module to provide stability during deployment of the airbag.
