Abstract

An air bag system for a vehicle. The air bag system includes an air bag body and an adjustment unit. The air bag body is configured to deploy upon input of shock to a vehicle. The adjustment unit is configured to move a position of the air bag body between a lower position and an upper position.

Claims

1. An air bag system for a vehicle, the air bag system comprising:

an air bag body configured to deploy upon input of shock to the vehicle; and

an adjustment unit configured to move a position of the air bag body between a lower position and an upper position.

2. The air bag system of claim 1, wherein the lower position and the upper position correspond to an occupant'"'"'s head position.

3. The air bag system as claimed in claim 1, wherein the air bag system is configured to be installed inside an interior of a vehicle having a roof that can be opened and closed, and

wherein the adjustment unit sets a deployment position of the air bag body to the upper position when the roof is opened, and sets the deployment position of the air bag body to the lower position when the roof is closed.

4. The air bag system as claimed in claim 3, wherein the adjustment unit, in response to a roof open/close signal, adjusts the position of the air bag body.

5. The air bag system as claimed in claim 1, wherein the adjustment unit is configured to lift the air bag body to the upper position and lower the air bag body to the lower position.

6. The air bag system as claimed in claim 5, wherein the adjustment unit comprises a guide rail portion guiding the air bag body upward and downward, and

wherein an upper end portion of the guide rail portion is arranged to be inclined against a deployment direction of the air bag body.

7. The air bag system as claimed in claim 5, wherein the adjustment unit comprises a guide rail portion guiding the air bag body upward and downward, and

wherein a position of an upper end of the guide rail portion corresponds to the upper position of the air bag body, and the upper end of the guide rail portion is inclined in a horizontal direction.

8. The air bag system as claimed in claim 1, wherein the air bag system is configured to be installed in a side portion of the vehicle.

9. The air bag system as claimed in claim 1, wherein the air bag system is configured to be installed in a back seat portion of the vehicle.

10. The air bag system as claimed in claim 1, wherein the adjustment unit comprises slits guiding the air bag body upward and downward.

11. The air bag system as claimed in claim 1, wherein the adjustment unit comprises a drum configured to raise and lower the air bag body.

12. A vehicle comprising the air bag system of claim 1.

13. A method of deploying an air bag body disposed in a vehicle, the method comprising:

adjusting a position of the air bag body according to a vehicle occupant'"'"'s head position; and

deploying the air bag body in response to a shock to the vehicle.

14. The method as claimed in claim 13, wherein the adjusting is in response to an open/close signal for a roof of the vehicle.

15. An air bag system for a vehicle, the air bag system comprising:

means for deploying an air bag body in response to a shock to the vehicle; and

means for adjusting a position of the air bag body between a lower position and an upper position.
