Vehicle airbag system
An assembly includes a seat. The assembly includes a housing. The assembly includes an airbag inflatable to an inflated position having a first inflatable leg and a second inflatable leg extending from the housing, and an inflatable member extending from the first inflatable leg to the second inflatable leg. The assembly includes a tether having a first end fixed to the first inflatable leg and a second end spaced from the first end and the airbag.
1. An assembly comprising:
a seat;
a housing;
an airbag inflatable to an inflated position and having a first inflatable leg and a second inflatable leg extending from the housing along a longitudinal axis, and an inflatable member extending from the first inflatable leg to the second inflatable leg along a lateral axis; and
a tether having a first end fixed to the first inflatable leg and a second end spaced from the first end and the airbag.
2. The assembly of claim 1 , wherein the inflatable member is elongated upward and away from the seat when the airbag is in the inflated position.
3. The assembly of claim 1 , wherein the seat is rear-facing.
4. The assembly of claim 1 , wherein the second end of the tether is behind the seat.
5. The assembly of claim 1 , further comprising a vehicle roof, the housing supported by the roof, and the second end of the tether fixed to the vehicle roof.
6. The assembly of claim 1 , further comprising a vehicle roof, the inflatable member spaced from the vehicle roof when the airbag is in the inflated position.
7. The assembly of claim 1 , wherein the seat includes a seat back defining a midpoint, the first and second inflatable legs extending below the midpoint when the airbag is in the inflated position.
8. The assembly of claim 1 , further comprising a processor and a memory storing instructions executable by the processor to actuate the airbag in response to detecting a vehicle rear impact.
9. The assembly of claim 1 , further comprising:
a second seat, the seat and the second seat positioned to face each other;
a second housing;
a second airbag inflatable to an inflated position having a first inflatable leg and a second inflatable leg extending from the housing, and an inflatable member extending from the first inflatable leg to the inflatable second leg; and
a second tether having a first end fixed to the first inflatable leg of the second airbag and a second end spaced from the first end of the tether and the second airbag.
10. The assembly of claim 9 , further comprising a processor and a memory storing instructions executable by the processor to actuate the airbag and to refrain from actuating the second airbag upon detecting a vehicle impact.
11. An assembly comprising:
a housing;
an airbag inflatable to an inflated position having a first inflatable leg and a second inflatable leg extending from the housing and along a longitudinal axis, and an inflatable member extending from the first inflatable leg to the second inflatable leg along a lateral axis; and
a tether having a first end fixed to the first inflatable leg and a second end spaced from the first end and the airbag.
12. The assembly of the claim 11 , wherein the first inflatable leg has a first end and a second end spaced from the first end along the longitudinal axis, and a first length at the first end and a second length at the second end that is greater than the first length, when the airbag is in the inflated position.
13. The assembly of claim 11 , further comprising a second tether external of the airbag and having a first end fixed to the first inflatable leg and a second end spaced from the first end and the airbag along the longitudinal axis.
14. The assembly of claim 13 , wherein the first end of the tether is spaced from the first end of the second tether along a vertical axis.
15. The assembly of claim 13 , wherein the first end of the tether is spaced from the first end of the second tether along the longitudinal axis.
16. The assembly of claim 13 , wherein the second end of the tether and the second end of the second tether are fixed at a same location.
17. The assembly of claim 11 , wherein the inflatable member is arcuate when the airbag is in the inflated position.
18. The assembly of claim 11 , wherein the first inflatable leg includes an inner panel and an outer panel spaced from the inner panel along the lateral axis, and a plurality of panels extending from the inner panel to the outer panel within the airbag.
19. The assembly of claim 11 , wherein the inflatable member includes a front panel and a rear panel spaced from the front panel along the longitudinal axis and a plurality of panels extending from the front panel to the rear panel within the airbag.
20. The assembly of claim 11 , wherein the first inflatable leg includes a plurality of panels internal of the airbag and extending to distal edges, the distal edges spaced from each other and free of attachment to other panels.
