Abstract

A seat includes a seatback having an exterior panel. The seat includes a first member and a second member each being inflatable to an inflated position and defining an inflation chamber, the inflation chambers spaced from each other. The exterior panel extends between and is secured to the first member and the second member external to the inflation chambers in the inflated position.

First claim

What is claimed is:

1. A seat comprising:
a seatback having an exterior panel;
a first member and a second member each being inflatable to an inflated position and defining an inflation chamber, the inflation chambers spaced from each other;
the exterior panel extending between and secured to the first member and the second member external to the inflation chambers in the inflated position; and
a tether including a first end secured to the exterior panel and a second end secured to the seatback other than to the exterior panel.

2. The seat of claim 1 , wherein the seatback incudes a second exterior panel spaced from the exterior panel when the first and second members are in the inflated position.

3. The seat of claim 2 , wherein the first and second members are inflatable from an uninflated position to the inflated position, and the exterior panel abuts the second exterior panel when the first and second members are in the uninflated position.

4. The seat of claim 3 , wherein the exterior panel is releasably fixed to the second exterior panel when the first and second members are in the uninflated position.

5. The seat of claim 1 , wherein the first member in the inflated position is parallel to the second member in the inflated position.

6. The seat of claim 1 , wherein the seatback defines a top-to-bottom axis and the first member and the second member in the inflated position each extend along the top-to-bottom axis.

7. The seat of claim 1 , wherein the first member in the inflated position is spaced from the second member in the inflated position by a threshold distance.

8. The seat of claim 7 , wherein the threshold distance is based on a shoulder width of a standard crash test dummy.

9. The seat of claim 1 , further comprising a third member inflatable to an inflated position and extending between the first member and the second member in the inflated position.

10. The seat of claim 9 , further comprising a fourth member inflatable to an inflated position and extending between the first member and the second member in the inflated position and spaced from the third member.

11. The seat of claim 10 , wherein the exterior panel is between the third member and the fourth member in the inflated position.

12. An airbag assembly comprising:
a housing;
a first member and a second member spaced from the first member, the first member and the second member each supported by the housing and inflatable from an uninflated position to an inflated position, the first member in the inflated position is spaced from the second member in the inflated position by a threshold distance based on a shoulder width of a standard crash test dummy such that the shoulders of the standard crash test dummy contact the first member and the second member and a head of the standard crash test dummy fits between the first member and the second member; and
an exterior panel secured to the first member and the second member and disposed outside of the housing and having a class-A surface while the first member and the second member are in the uninflated position.

13. The airbag assembly of claim 12 , wherein the exterior panel is made of fabric.

14. The airbag assembly of claim 12 , wherein the exterior panel is made of leather.

15. The airbag assembly of claim 12 , wherein the exterior panel includes an inner layer and an outer layer relative to the housing.

16. The airbag assembly of claim 15 , wherein the inner layer is foam.

17. The airbag assembly of claim 12 , wherein the exterior panel is an upholstered surface.

18. A seat comprising:
a seatback having an exterior panel;
a first member and a second member each being inflatable to an inflated position and defining an inflation chamber, the inflation chambers spaced from each other; and
the exterior panel extending between and secured to the first member and the second member external to the inflation chambers in the inflated position;
wherein the first member and the second member in the inflated position each have an arcuate shape with a first end and a second end opposite the first end, the first end and the second end secured to the seatback.

19. The seat of claim 18 , wherein the arcuate shape of the first member defines an apex located a distance from the seatback, and further comprising a tether including a first end secured to the exterior panel and a second end secured to the seatback other than to the exterior panel and having a length that is less than the distance from the apex to the seatback.
