Airbag supported by an armrest of a vehicle seat
An assembly includes a vehicle seat. The assembly includes an armrest supported by the vehicle seat. The armrest includes an upright portion elongated along an axis and an arm support portion supported by the upright portion. The assembly includes an airbag supported by the arm support portion of the armrest. The airbag inflatable to an inflated position. The airbag includes an upper portion extending upwardly from the arm support portion when the airbag is in the inflated position and a lower portion extending downwardly from the arm support portion when the airbag is in the inflated position. The upper portion is vehicle-inboard of the axis and the lower portion being vehicle-outboard of the axis.
1. An assembly comprising:
a vehicle seat;
an armrest supported by the vehicle seat, the armrest including an upright portion elongated along an axis and an arm support portion supported by the upright portion; and
an airbag supported by the arm support portion of the armrest, the airbag inflatable to an inflated position;
the airbag including an upper portion extending upwardly from the arm support portion when the airbag is in the inflated position and a lower portion extending downwardly from the arm support portion when the airbag is in the inflated position;
the upper portion being vehicle-inboard of the axis and the lower portion being vehicle-outboard of the axis.
2. The assembly of claim 1 , wherein the lower portion of the airbag abuts the upright portion of the armrest when the airbag is in the inflated position.
3. The assembly of claim 1 , wherein the upper portion of the airbag includes an inboard panel and the lower portion of the airbag includes an outboard panel, the inboard panel being spaced cross-vehicle from the outboard panel.
4. The assembly of claim 3 , wherein the inboard panel is offset vehicle-inboard from the axis when the airbag is in the inflated position and the outboard panel is offset vehicle-outboard from the axis when the airbag is in the inflated position.
5. The assembly of claim 3 , wherein the vehicle seat defines an occupant seating area, the lower portion of the airbag being between the occupant seating area and the upright portion of the armrest.
6. The assembly of claim 3 , wherein the outboard panel is spaced from the axis by a first distance and the outboard panel is spaced from the inboard panel by a second distance, the second distance being larger than the first distance.
7. The assembly of claim 1 , wherein the upper portion is vehicle-inboard of the vehicle seat.
8. The assembly of claim 1 , wherein the vehicle seat defines an occupant head area and an occupant hip area below the occupant head area, the upper portion being adjacent the occupant head area and the lower portion being adjacent the occupant hip area.
9. The assembly of claim 1 , wherein the airbag defines an inflation chamber that extends from the upper portion to the lower portion of the airbag.
10. The assembly of claim 1 , wherein the upper portion is elongated upwardly along the axis and the lower portion is elongated downwardly along the axis.
11. The assembly of claim 1 , wherein the airbag is supported by and inflatable from a seat-inboard side of the arm support portion.
12. The assembly of claim 1 , wherein the armrest is extendable upwardly along the axis from a lowered position to a raised position.
13. The assembly of claim 12 , wherein the airbag is inflatable from an uninflated position to the inflated position, the airbag being in the inflated position when the armrest is in the raised position and the airbag being in the uninflated position when the armrest is in the lowered position.
14. The assembly of claim 1 , wherein the arm support portion is movable upwardly along the axis.
15. The assembly of claim 1 , wherein the upright portion includes a track elongated along the axis, the arm support portion being movable along the track from a lowered position to a raised position.
16. The assembly of claim 1 , wherein the upright portion includes a piston elongated along the axis, the arm support portion being movable along the axis by the piston.
17. The assembly of claim 16 , further comprising a pyrotechnic device operatively coupled to the piston.
18. The assembly of claim 1 , further comprising a computer including a processor and a memory storing instructions executable by the processor to:
initiate movement of the armrest along the axis from a lowered position to a raised position; and
inflate the airbag to the inflated position after initiation of movement of the armrest.
19. The assembly of claim 18 , wherein the instructions to move the armrest along the axis from the lowered position to the raised position includes instructions to activate a pyrotechnic device to move the armrest along the axis.
