Occupant protection apparatus for vehicle
View Patent ↗An occupant protection apparatus for a vehicle includes: a main bag that, when an occupant who is seated in a seat of the vehicle is about to fall forward, is deployed in front of the occupant and is capable of supporting the head and upper body of the occupant; a sub-bag that is deployed on a longitudinal centerline side of the head of the occupant who plunges into the main bag; and a center bag that is deployed in the center in a lateral direction of the vehicle. The sub-bag is deployed on a door side of the center bag and, when subjected to a load of the head of the occupant who plunges into at least the main bag while being inclined toward the longitudinal centerline side, comes into contact with the lateral side of the center bag on the door side so as to overlap it.
1. A occupant protection apparatus for a vehicle comprising:
a main bag that, when an occupant who is seated in a seat of the vehicle and is about to fall forward, is deployed in front of the occupant and is capable of supporting a head and upper body of the occupant;
a sub-bag that is deployed and is capable to be next to a longitudinal centerline side of the head of the occupant who plunges into the main bag; and
a center bag that is deployed in a fore-aft direction of the vehicle from a center of the vehicle in a width direction of the vehicle,
wherein the sub-bag is deployed on a door side of the center bag and, when subjected to a load of the head of the occupant who plunges into at least the main bag while being inclined toward the longitudinal centerline side, comes into contact with a lateral side of the center bag on the door side so as to overlap the lateral side of the center bag.
2. The occupant protection apparatus for a vehicle according to claim 1 , wherein the center bag comprises a far-side airbag that is deployed in the center in the width direction of the vehicle.
3. The occupant protection apparatus for a vehicle according to claim 1 , wherein a contact surface of at least one of the center bag and the sub-bag which come into contact with each other so as to overlap each other is formed so as to reduce friction.
4. The occupant protection apparatus for a vehicle according to claim 2 , wherein a contact surface of at least one of the center bag and the sub-bag which come into contact with each other so as to overlap each other is formed so as to reduce friction.
5. The occupant protection apparatus for a vehicle according to claim 1 , wherein
the center bag is deployed from a rear portion to a front portion of the vehicle, and
the contact surface of at least one of the center bag and the sub-bag is formed so as to reduce friction in the longitudinal direction of the vehicle and suppress slippage in the vertical direction of the vehicle.
6. The occupant protection apparatus for a vehicle according to claim 2 , wherein
the center bag is deployed from a rear portion to a front portion of the vehicle, and
the contact surface of at least one of the center bag and the sub-bag is formed so as to reduce friction in the longitudinal direction of the vehicle and suppress slippage in the vertical direction of the vehicle.
7. The occupant protection apparatus for a vehicle according to claim 1 , wherein the center bag is deployed to a center side of the seat of the vehicle.
8. The occupant protection apparatus for a vehicle according to claim 1 , wherein the center bag is deployed from a side of the seat opposite a door of the vehicle.
9. The occupant protection apparatus for a vehicle according to claim 1 , wherein the center bag is deployed between the occupant and a second occupant.
10. The occupant protection apparatus for a vehicle according to claim 1 , wherein the center of the vehicle and the door side of the vehicle are on opposite sides of the seat.
11. The occupant protection apparatus for a vehicle according to claim 1 , wherein the center bag is deployed from the seat.
12. The occupant protection apparatus for a vehicle according to claim 1 , wherein the center bag is deployed so as to prevent a position of the occupant from traversing over a center console of the vehicle disposed in the center of the vehicle in the width direction of the vehicle.
13. The occupant protection apparatus for a vehicle according to claim 1 , wherein in a deployed state, the sub-bag and the center bag are disposed sequentially from the door side to the center of the vehicle in the width direction of the vehicle.
14. The occupant protection apparatus for a vehicle according to claim 2 , wherein in a deployed state, the sub-bag and the center bag are disposed sequentially from the door side to the center of the vehicle in the width direction of the vehicle.
15. The occupant protection apparatus for a vehicle according to claim 1 , wherein in a deployed state, the center bag protrudes past the main bag in the longitudinal direction of the vehicle.
16. The occupant protection apparatus for a vehicle according to claim 1 , wherein the main bag and the sub-bag are deployed towards a rear of the vehicle, and
wherein the center bag is deployed towards a front of the vehicle.
17. The occupant protection apparatus for a vehicle according to claim 1 , further comprising a center tunnel disposed between the occupant of the vehicle and a second occupant of the vehicle,
wherein the center bag is deployed over the center tunnel.
18. The occupant protection apparatus for a vehicle according to claim 6 , wherein the sub-bag is deployed to a center side of the seat of the vehicle.
19. The occupant protection apparatus for a vehicle according to claim 7 , wherein the sub-bag is deployed to the center side of the seat of the vehicle.
20. The occupant protection apparatus for a vehicle according to claim 9 , wherein the sub-bag is deployed between the occupant and the second occupant.
