An airbag includes a panel, a secondary panel, and an opening. The panel defines an inflation chamber inflatable to an inflated position and includes a valley in the inflated position. The secondary panel is connected to the panel on opposite sides of the valley and extends across the valley to define a secondary chamber between the secondary panel and the panel. The opening extends through the panel from the inflation chamber to the secondary chamber. During a vehicle impact, the momentum of the occupant may move the occupant towards the secondary panel. The secondary panel may absorb energy from the occupant and reduce or prevent the head of the occupant from rotating.

1. An airbag comprising; a panel defining an inflation chamber inflatable to an inflated position, the panel having a top end and a bottom end spaced from the top end and a valley in the inflated position extending in a direction from the top end to the bottom end;a secondary panel connected to the panel on opposite sides of the valley and extending across the valley to define a secondary chamber between the secondary panel and the panel; andan opening extending through the panel from the inflation chamber to the secondary chamber. 2. The airbag according to claim 1, wherein the secondary panel includes a top edge, a bottom edge spaced from the top edge, and sides extending from the top edge to the bottom edge, each of the top edge, bottom edge and sides connected to the panel. 3. The airbag according to claim 1, wherein the secondary panel is connected to the panel in the valley. 4. The airbag according to claim 1, wherein the secondary panel is external to the inflation chamber. 5. The airbag according to claim 1, wherein the secondary panel is generally planar when the panel is in the inflated position. 6. The airbag according to claim 1, wherein the panel defines a second inflation chamber separated from the inflation chamber by the valley, and wherein the second inflation chamber and the inflation chamber are disposed on opposite sides of the valley. 7. The airbag according to claim 6, further comprising a second opening extending through the panel from the second inflation chamber to the secondary chamber. 8. The airbag according to claim 7, wherein the panel separates the inflation chamber and the second inflation chamber to prevent fluid communication there between. 9. The airbag according to claim 1, wherein the panel includes a first segment and a second segment connected to the first segment in the valley. 10. A system comprising: a roof;an airbag supported by the roof and being inflatable away from the roof to an inflated position, the airbag including a panel having a valley in the inflated position;a secondary panel connected to the panel on opposite sides of the valley and extending across the valley to define a secondary chamber between the secondary panel and the panel;an opening extending through the panel to the secondary chamber; andwherein the panel includes a top end adjacent to the roof and a bottom end opposite the top end, and wherein the valley extends in a direction from the top end to the bottom end in the inflated position. 11. The system according to claim 10, wherein the secondary panel includes a top edge, a bottom edge spaced from the top edge, and sides extending from the top edge to the bottom edge, each of the top edge, bottom edge and sides connected to the panel. 12. The system according to claim 10, wherein the secondary panel is connected to the panel in the valley. 13. The system according to claim 10, wherein the secondary panel is generally planar when the panel is in the inflated position. 14. The system according to claim 10, wherein the panel defines an inflation chamber, and wherein the secondary panel is external to the inflation chamber. 15. The system according to claim 10, wherein the panel defines a second inflation chamber separated from the inflation chamber by the valley, and wherein the second inflation chamber and the inflation chamber are disposed on opposite sides of the valley. 16. The system according to claim 15, further comprising a second opening extending through the panel from the second inflation chamber to the secondary chamber. 17. The system according to claim 16, wherein the panel separates the inflation chamber and the second inflation chamber to prevent fluid communication there between. 18. The system according to claim 10, further comprising a seat including a seat bottom and a seatback extending upwardly from the seat bottom, and wherein the seat bottom and the seatback define an occupant region, the secondary panel being disposed adjacent to the occupant region when the panel is in the inflated position. 19. The system according to claim 10, wherein the panel includes a first segment and a second segment connected to the first segment in the valley. 20. A system comprising: a roof;an airbag supported by the roof and being inflatable away from the roof to an inflated position, the airbag including a panel having a valley in the inflated position;a secondary panel connected to the panel on opposite sides of the valley and extending across the valley to define a secondary chamber between the secondary panel and the panel;an opening extending through the panel to the secondary chamber; andwherein the secondary panel is connected to the panel in the valley. 21. An airbag comprising; a panel defining an inflation chamber inflatable to an inflated position, the panel having a valley in the inflated position;a secondary panel connected to the panel on opposite sides of the valley and extending across the valley to define a secondary chamber between the secondary panel and the panel;an opening extending through the panel from the inflation chamber to the secondary chamber;wherein the panel defines a second inflation chamber separated from the inflation chamber by the valley, and wherein the second inflation chamber and the inflation chamber are disposed on opposite sides of the valley;a second opening extending through the panel from the second inflation chamber to the secondary chamber; andwherein the panel separates the inflation chamber and the second inflation chamber to prevent fluid communication there between. 22. A system comprising: a roof;an airbag supported by the roof and being inflatable away from the roof to an inflated position, the airbag including a panel having a valley in the inflated position;a secondary panel connected to the panel on opposite sides of the valley and extending across the valley to define a secondary chamber between the secondary panel and the panel;an opening extending through the panel to the secondary chamber;wherein the panel defines a second inflation chamber separated from the inflation chamber by the valley, and wherein the second inflation chamber and the inflation chamber are disposed on opposite sides of the valley;a second opening extending through the panel from the second inflation chamber to the secondary chamber; andwherein the panel separates the inflation chamber and the second inflation chamber to prevent fluid communication there between.
