Abstract

A seat including a seatback having a top and two sides extending downwardly from the top and an airbag supported by the top and the two sides of the seatback and including a tube inflatable forward and downward from the top. The airbag defining at least one inflation chamber in fluid communication with the tube. The inflation chamber extending from at least one side of the seatback towards the tube.

First claim

What is claimed is:

1. A seat comprising:
a seatback having a top and two sides extending downwardly from the top;
an airbag supported by the top and the two sides of the seatback and including a tube inflatable forward and downward from the top;
the airbag defining at least one inflation chamber in fluid communication with the tube, the tube being adjacent to the at least one inflation chamber, the at least one inflation chamber extending from at least one side of the seatback towards the tube; and
the tube includes a plurality of holes spaced from each other along an entire length of the tube in an inflated position from an end of the tube at the top of the seatback to an opposite end of the tube, the tube in fluid communication with the adjacent inflation chamber through the plurality of holes.

2. The seat of claim 1 , wherein the tube is disposed in the inflation chamber.

3. The seat of claim 1 , wherein the tube is external to at least one inflation chamber.

4. The seat of claim 1 , further comprising an inflator in fluid communication with the tube.

5. The seat of claim 1 , further comprising a second tube spaced from the tube, the second tube in fluid communication with at least one inflation chamber and inflatable forward and downward from the top of the seatback.

6. The seat of claim 5 , wherein the tube and the second tube each include a plurality of holes spaced from each other along the respective tube, the tubes in fluid communication with at least one inflation chamber through the holes.

7. The seat of claim 5 , wherein the tubes are disposed in the inflation chamber.

8. The seat of claim 5 , wherein the tubes are external to at least one inflation chamber.

9. The seat of claim 8 , wherein the tubes partially define one inflation chamber therebetween, the inflation chamber in fluid communication with at least one tube.

10. The seat of claim 5 , further comprising two inflators, one inflator is in fluid communication with each tube.

11. The seat of claim 1 , wherein the airbag, in an inflated position, is configured to extend from the seatback around a lower leg of an occupant seated against the seatback.

12. The seat of claim 1 , further comprising a reinforcement having a first leg fixed to the top of the seatback and a second leg pivotally coupled to the first leg, the airbag extending from the first leg to the second leg.

13. The seat of claim 12 , wherein the reinforcement defines a radial inflation path for the airbag, the path centered at a location where the second leg is pivotally coupled to the first leg.

14. The seat of claim 12 , wherein the second leg, in an inflated position, is configured to extend around a lower leg of an occupant seated in the seat.

15. The seat of claim 12 , wherein the tube extends from the first leg to the second leg of the reinforcement.

16. The seat of claim 1 , wherein the airbag includes a plurality of internal reinforcements each fixed to the airbag in the inflation chamber.

17. The seat of claim 16 , wherein the airbag includes a plurality of tethers each extending across the inflation chamber.

18. The seat of claim 1 , wherein the airbag includes a plurality of seams defining chambers therebetween.

19. The seat of claim 18 , wherein at least one of the seams includes at least one vent extending into adjacent chambers, adjacent chambers being in fluid communication through the respective vent.

20. A seat comprising:
a seatback having a top and two sides extending downwardly from the top;
an airbag supported by the top and the two sides of the seatback and including a tube inflatable forward and downward from the top;
the airbag defining at least one inflation chamber in fluid communication with the tube, the inflation chamber extending from at least one side of the seatback towards the tube; and
a reinforcement having a first leg fixed to the top of the seatback and a second leg pivotally coupled to the first leg, the airbag extending from the first leg to the second leg.
