Abstract

An assembly includes a seatback. The assembly includes a first airbag and a second airbag, each inflatable to an inflated position spaced from each other at the seatback and abutting each other in front of and spaced from the seatback. The assembly includes a sheet extending from the first airbag to the second airbag in front of where the first airbag abuts the second airbag in the inflated positions.

First claim

What is claimed is:

1. An assembly, comprising:
a seatback;
a first airbag and a second airbag, each supported within the seatback and inflatable to an inflated position spaced from each other at the seatback and abutting each other in front of and spaced from the seatback, the first airbag and the second airbag in the inflated positions each including a top portion and a front portion, the top portions extending arcuately from the seatback to the front portions and spaced from each other, the front portions extending toward and abutting each other; and
a sheet within the seatback prior to inflation of the first airbag and the second airbag, the sheet extending from the first airbag to the second airbag in front of where the first airbag abuts the second airbag in the inflated positions, and the sheet extending away from one of the front portions and toward the seatback.

2. The assembly of claim 1 , wherein the first airbag is in front of the second airbag where the first airbag abuts the second airbag in the inflated positions.

3. The assembly of claim 1 , wherein the seatback has a top, and the first airbag and the second airbag are supported at the top of the seatback.

4. The assembly of claim 1 , wherein the first airbag and the second airbag abut each other at a centerline defined by the seatback.

5. The assembly of claim 1 , wherein the front portions are thicker than the top portions.

6. The assembly of claim 1 , wherein the sheet extends along the top portions and the front portions of the first airbag and the second airbag.

7. The assembly of claim 1 , further comprising a side airbag supported by the seatback and inflatable to an inflated position between the seatback and the first airbag in the inflated position.

8. The assembly of claim 7 , further comprising a processor and a memory storing instructions executable by the processor to inflate the first airbag, and then inflate the side airbag.

9. The assembly of claim 1 , wherein the first airbag and the sheet are a same type of material.

10. The assembly of claim 1 , wherein the sheet is uninflatable.

11. The assembly of claim 1 , further comprising an inflator in fluid communication with the first airbag and the second airbag.

12. An assembly, comprising:
a seatback;
a first airbag and a second airbag, each inflatable to an inflated position spaced from each other at the seatback and abutting each other in front of and spaced from the seatback;
a sheet extending from the first airbag to the second airbag in front of where the first airbag abuts the second airbag in the inflated positions; and
a tether fixed to the seatback and extending to the sheet.

13. The assembly of claim 12 , further comprising a second tether fixed to the seatback and extending to the sheet, the second tether below the tether.

14. The assembly of claim 12 , wherein the tether is fixed to the sheet.

15. The assembly of claim 12 , wherein the tether is free of being directly fixed to the first airbag and is free of being fixed to the second airbag.

16. The assembly of claim 12 , wherein the seatback includes a first side and a second side opposite the first side, the tether extending from the first side of the seatback along the sheet to the second side of the seatback.

17. An assembly, comprising:
a seatback;
a first airbag and a second airbag, each inflatable to an inflated position spaced from each other at the seatback and abutting each other in front of and spaced from the seatback; and
a sheet extending from the first airbag to the second airbag in front of where the first airbag abuts the second airbag in the inflated positions, the sheet defining an opening between the first airbag and the second airbag in the inflated positions.

18. The assembly of claim 17 , wherein the opening is in front of and above the seatback.
