Abstract

A vehicle includes a bulkhead and an airbag inflatable to an inflated position. The airbag includes a forward-facing panel mounted to the bulkhead and a rearward-facing panel opposite the forward-facing panel. Then airbag in the inflated position has a left extension and a right extension extending from the rearward-facing panel, and an intermediate extension sandwiched between the left extension and the right extension. The intermediate extension extends from the rearward-facing panel farther than the left and right extensions. During a vehicle impact, the momentum of the occupant may move the occupant towards the airbag. The airbag may absorb energy from the head and knees of the occupant.

First claim

What is claimed is:

1 . A vehicle comprising:
a bulkhead; an airbag inflatable to an inflated position; the airbag including a forward-facing panel mounted to the bulkhead and a rearward-facing panel opposite the forward-facing panel; the airbag in the inflated position having a left extension and a right extension extending from the rearward-facing panel, and an intermediate extension sandwiched between the left and right extensions and extending from the rearward-facing panel farther than the left and right extensions.

2 . The vehicle of claim 1 , wherein the forward-facing panel faces the bulkhead.

3 . The vehicle of claim 1 , further comprising a base mounted to the bulkhead and supporting the airbag, the forward-facing panel and the rearward-facing panel being inflatable upwardly and downwardly relative to the base.

4 . The vehicle of claim 3 , wherein the rearward-facing panel includes a first portion extending upwardly relative to base to a first distal end spaced from the base.

5 . The vehicle of claim 4 , wherein the left extension, the right extension, and the intermediate extension each extend from the first portion.

6 . The vehicle of claim 4 , wherein the first portion includes an opening extending into each of the left extension, the right extension, and the intermediate extension, and wherein a plurality of tethers extend across the opening.

7 . The vehicle of claim 4 , wherein the rearward-facing panel includes a second portion extending downwardly relative to the base to a second distal end.

8 . The vehicle of claim 7 , wherein the first portion and the second portion are rolled in opposite directions relative to the base in an uninflated position.

9 . The vehicle of claim 1 , further comprising a deflector extending from a base adjacent to the forward-facing panel, the deflector extending transverse to the bulkhead.

10 . The vehicle of claim 1 , further comprising a roof and a floor spaced from the roof, the airbag in the inflated position extending from the roof to the floor.

11 . The vehicle of claim 10 , further comprising a base mounted to the bulkhead and supporting the airbag, and the rearward-facing panel includes a first portion extending upwardly relative to the base along the roof to a first distal end adjacent the roof, the left extension, the right extension, and the intermediate extension each extending downwardly from the first portion towards the floor.

12 . The vehicle of claim 1 , further comprising front pillars spaced from each other in a cross-vehicle direction, the airbag extending from the one front pillar to the other front pillar.

13 . The vehicle of claim 1 , further comprising front seats spaced from each other, the intermediate extension in the inflated position disposed between the one front seat and the other front seat.

14 . The vehicle of claim 1 , wherein the intermediate extension is attached to both the left extension and the right extension.

15 . An airbag assembly comprising:
a base; an airbag inflatable to an inflated position; the airbag including a forward-facing panel mounted to the base and a rearward-facing panel opposite the forward-facing panel; the airbag in the inflated position having a left extension and a right extension extending from the rearward-facing panel, and an intermediate extension sandwiched between the left and right extensions and extending from the rearward-facing panel farther than the left and right extensions.

16 . The airbag assembly of claim 15 , wherein the forward-facing panel and the rearward-facing panel are inflatable upwardly and downwardly relative to the base.

17 . The airbag assembly of claim 15 , wherein the rearward-facing panel includes a first portion extending upwardly relative to the base to a first distal end.

18 . The airbag assembly of claim 17 , wherein the left extension, the right extension, and the intermediate extension each extend downwardly from the first portion.

19 . The airbag assembly of claim 17 , wherein the rearward-facing panel includes a second portion extending downwardly relative to the base to a second distal end, the second distal end spaced from the first distal end in the inflated position.

20 . The airbag assembly of claim 19 , wherein the first portion and the second portion are rolled in opposite directions relative to the base in an uninflated position.
