Abstract

An airbag device is disclosed. The airbag device comprises an airbag housing, an inflator connected to the airbag housing and capable of exerting an deployment force, a cushion assembly accommodated in the airbag housing and having a cushion deployable outside the airbag housing when the deployment force of the inflator is exerted thereon, and a pad mounted so as to cause friction with at least some parts of the cushion assembly. The eccentric deployment of the cushion is prevented, and the initial deployment force of the cushion is suppressed, thereby effectively coping with POF and OOP.

Claims

1. An airbag device, comprising:

an airbag housing;

an inflator connected to the airbag housing and capable of exerting an deployment force;

a cushion assembly accommodated in the airbag housing and having a cushion deployable outside the airbag housing when the deployment force of the inflator is exerted thereon; and

a pad mounted so as to cause friction with at least some parts of the cushion assembly.

2. The airbag device of claim 1, wherein the cushion assembly consists of the cushion and a cushion cover covered so as to cover at least some parts of the cushion.

3. The airbag device of claim 1, wherein the pad is attached to an inner side of the cushion cover.

4. The airbag device of claim 1, wherein the pad is attached to the front side of the cushion accommodated in the airbag housing.

5. The airbag device of claim 1, wherein the pad is attached to an inner wall of the airbag housing.

6. The airbag device of claim 5, wherein the pad is attached to a side wall of the airbag housing.

7. The airbag device of claim 1, wherein the pad is made of rubber.

8. The airbag device of claim 1, wherein the pad is formed by laminating a plurality of rubber plates and connecting the adjacent rubber plates.

9. The airbag device of claim 1, wherein the pad is formed by laminating two rubber plates and connecting some parts of the two laminated rubber plates.

10. The airbag device of claim 1, wherein the airbag device is mounted on a vehicle, and some parts of the pad are interposed between the body of the vehicle where the airbag housing is mounted and the airbag housing.

11. The airbag device of claim 1, wherein some parts of the pad are interposed between the cushion assembly and the airbag housing.

12. An airbag device, comprising:

an airbag housing mounted to an instrument panel;

an inflator connected to the airbag housing and capable of exerting an deployment force;

a cushion accommodated in the airbag housing and deployable outside the airbag housing when the deployment force of the inflator is exerted thereon;

a cushion cover covered on the outer side of the cushion; and

a pad interposed between the cushion cover and the cushion.

13. The airbag device of claim 12, wherein the pad is attached to an inner side of the cushion cover.

14. The airbag device of claim 13, wherein the pad is attached to the front side of the cushion accommodated in the airbag housing.

15. The airbag device of claim 13, wherein the pad is made of rubber.

16. The airbag device of claim 13, wherein the pad is formed by laminating a plurality of rubber plates and connecting the adjacent rubber plates.

17. An airbag device, comprising:

an airbag housing mounted to an instrument panel;

an inflator connected to the airbag housing and capable of exerting an deployment force;

a cushion accommodated in the airbag housing and deployable outside the airbag housing when the deployment force of the inflator is exerted thereon;

a cushion cover covered on the outer side of the cushion; and

a pad interposed between the cushion cover and the airbag housing

18. The airbag device of claim 17, wherein the pad is attached to an inner side of the cushion cover.

19. The airbag device of claim 17, wherein the pad is made of rubber.

20. The airbag device of claim 17, wherein the pad is formed by laminating a plurality of rubber plates and connecting the adjacent rubber plates.
