Vehicle airbag assembly
A vehicle includes a body defining a passenger cabin with a front end, the body having a bulkhead at the front end of the passenger cabin. The vehicle includes a telescoping member supported by the bulkhead and movable from a stowed position to a deployed position. The vehicle includes an airbag supported by the telescoping member and movable from the stowed position to the deployed position, the airbag inflatable from an uninflated position to an inflated position.
1. A vehicle, comprising:
a body defining a passenger cabin with a front end, the body having a bulkhead at the front end of the passenger cabin;
a telescoping member supported by the bulkhead and movable from a stowed position to a deployed position;
an airbag supported by the telescoping member and movable from the stowed position to the deployed position, the airbag inflatable from an uninflated position to an inflated position;
a seat assembly facing the airbag and defining a recline angle; and
a computer having a processor and a memory storing instructions executable by the processor to:
compare the recline angle of the seat assembly to a threshold recline angle;
detect a certain impact to the vehicle;
in response to determining that the recline angle is greater than the threshold recline angle and detecting the certain impact to the vehicle, move the telescoping member to the deployed position and inflate the airbag; and
in response to determining that the recline angle is not greater than the threshold recline angle and detecting the certain impact to the vehicle, inflate the airbag without moving the telescoping member to the deployed position.
2. The vehicle of claim 1 , further comprising a plate supported by the telescoping member and movable from the stowed position to the deployed position, the airbag supported by the plate.
3. The vehicle of claim 2 , further comprising an inflator supported by the plate and in fluid communication with the airbag to permit inflation medium flow from the inflator to the airbag.
4. The vehicle of claim 1 , wherein the telescoping member includes a first member and a second member slidable along the first member away from the bulkhead to the deployed position.
5. The vehicle of claim 4 , further comprising a lock configured to maintain the second member at the deployed position.
6. The vehicle of claim 4 , wherein the first member is slidable rearward from the bulkhead to the deployed position.
7. The vehicle of claim 6 , further comprising a first lock configured to maintain the second member at the deployed position and a second lock configured to maintain the first member at the deployed position.
8. The vehicle of claim 1 , wherein the airbag in the inflated position is spaced from the bulkhead with the telescoping member at the deployed position.
9. The vehicle of claim 1 , further comprising a tether extending from the airbag to the bulkhead.
10. The vehicle of claim 1 , wherein the bulkhead includes an instrument panel.
11. The vehicle of claim 1 , further comprising a pyrotechnic material that moves the telescoping member to the deployed position upon actuation.
12. The vehicle of claim 1 , further comprising a second airbag inflatable to a second inflated position, the second airbag in the second inflated position being below the airbag in the inflated position.
13. The vehicle of claim 12 , wherein the airbag is in fluid communication with the second airbag to permit inflation medium to flow from the airbag to the second airbag.
14. The vehicle of claim 12 , wherein the second airbag extends from the airbag toward the bulkhead.
15. The vehicle of claim 12 , further comprising a tether extending from the second airbag to the bulkhead.
16. The vehicle of claim 1 , wherein the instructions include instructions to inflate the airbag a threshold amount of time after moving the telescoping member to the deployed position.
17. A vehicle, comprising:
a body defining a passenger cabin with a front end, the body having a bulkhead at the front end of the passenger cabin;
a telescoping member supported by the bulkhead and movable from a stowed position to a deployed position;
an airbag supported by the telescoping member and movable from the stowed position to the deployed position, the airbag inflatable from an uninflated position to an inflated position; and
a tether extending from the airbag to the bulkhead.
18. A vehicle, comprising:
a body defining a passenger cabin with a front end, the body having a bulkhead at the front end of the passenger cabin;
a telescoping member supported by the bulkhead and movable from a stowed position to a deployed position;
an airbag supported by the telescoping member and movable from the stowed position to the deployed position, the airbag inflatable from an uninflated position to an inflated position; and
a second airbag inflatable to a second inflated position, the second airbag in the second inflated position being below the airbag in the inflated position.
19. The vehicle of claim 18 , wherein the airbag is in fluid communication with the second airbag to permit inflation medium to flow from the airbag to the second airbag.
20. The vehicle of claim 18 , wherein the second airbag extends from the airbag toward the bulkhead.
