Abstract

An air bag system for a vehicle including a cover for housing an air bag in a folded state along a side of a roof of the vehicle is provided. The cover includes a pair of opposed walls approximately parallel to each other, a connection wall that connects the pair of the opposed walls, an opening that is defined by the pair of the opposed walls and opens downward, a bent section that is formed to be bent three-dimensionally upward and inward so as to go along a face shape of the vehicle body where the cover is installed, at least one load transmission part that is provided on the connection wall so as to transmit a load from a vehicle interior side to a vehicle exterior side, and a locking portion that is provided on the load transmission part on the vehicle exterior side.

Claims

1. An air bag system for a vehicle comprising a cover for housing an air bag in a folded state along a side of a roof of the vehicle,

the cover comprising:

a pair of opposed walls approximately parallel to each other;

a connection wall that connects the pair of opposed walls

an opening that is defined by the pair of opposed walls and opens downward,

a bent section that is formed to be bent three-dimensionally upward and inward so as to extend along a face shape of the vehicle body where the cover is installed;

at least one load transmission part that is provided on the connection wall so as to transmit a load from a vehicle interior side to a vehicle exterior side; and

a locking portion that is provided on the load transmission part on the vehicle exterior side.

2. The air bag system for a vehicle according to claim 1, wherein the cover further comprises at least one sub-locking portion provided lower than the connection wall, and a finger-insert provided on the vehicle interior side of the sub-locking portion.

3. The air bag system for a vehicle according to claim 1, wherein the bent section is provided at a position corresponding to an upper portion of a pillar.

4. The air bag system for a vehicle according to claim 2, wherein the bent section is provided at a position corresponding to an upper portion of a pillar.

5. The air bag system for a vehicle according to claim 1, wherein the cover is further provided on the connection wall with reinforcement ribs parallel to a lateral direction of the vehicle body.

6. The air bag system for a vehicle according to claim 2, wherein the cover is further provided on the connection wall with reinforcement ribs parallel to a lateral direction of the vehicle body.

7. The air bag system for a vehicle according to claim 3, wherein the cover is further provided on the connection wall with reinforcement ribs parallel to a lateral direction of the vehicle body.

8. The air bag system for a vehicle according to claim 4, wherein the cover is further provided on the connection wall with reinforcement ribs parallel to a lateral direction of the vehicle body.

9. The air bag system for a vehicle according to claim 1, wherein

one of the pair of opposed walls on the vehicle exterior side further comprises an outer-side wall face, and

the outer-side wall face at the bent section downwardly extends lower than the outer-side wall face at other positions.

10. The air bag system for a vehicle according to claim 2, wherein

one of the pair of opposed walls on the vehicle exterior side further comprises an outer-side wall face, and

the outer-side wall face at the bent section downwardly extends lower than the outer-side wall face at other positions.

11. The air bag system for a vehicle according to claim 3, wherein

one of the pair of opposed walls on the vehicle exterior side further comprises an outer-side wall face, and

the outer-side wall face at the bent section downwardly extends lower than the outer-side wall face at other positions.

12. The air bag system for a vehicle according to claim 4, wherein

one of the pair of opposed walls on the vehicle exterior side further comprises an outer-side wall face, and

the outer-side wall face at the bent section downwardly extends lower than the outer-side wall face at other positions.

13. The air bag system for a vehicle according to claim 5, wherein

one of the pair of opposed walls on the vehicle exterior side further comprises an outer-side wall face, and

the outer-side wall face at the bent section downwardly extends lower than the outer-side wall face at other positions.

14. The air bag system for a vehicle according to claim 6, wherein

one of the pair of opposed walls on the vehicle exterior side further comprises an outer-side wall face, and

the outer-side wall face at the bent section downwardly extends lower than the outer-side wall face at other positions.

15. The air bag system for a vehicle according to claim 7, wherein

one of the pair of opposed walls on the vehicle exterior side further comprises an outer-side wall face, and

the outer-side wall face at the bent section downwardly extends lower than the outer-side wall face at other positions.

16. The air bag system for a vehicle according to claim 8, wherein

one of the pair of opposed walls on the vehicle exterior side further comprises an outer-side wall face, and

the outer-side wall face at the bent section downwardly extends lower than the outer-side wall face at other positions.

17. The air bag system for a vehicle according to claim 1, wherein, in a cross section parallel to the lateral direction of the vehicle body, the pair of opposed walls are formed to extend generally vertically downward such that an opening direction angle of the opening of the opposed walls relative to the vertical direction becomes approximately zero.
