Abstract

An airbag module includes a module cover, an airbag configured to inflate in an event of a vehicle emergency, and an inflator configured to provide gas for inflating the airbag. The inflator and the airbag are connected to a retainer, and the module cover and the retainer are connected to form an enclosure volume. A ratio of the enclosure volume to a portion of the enclosure volume that is occupied by components of the airbag module is 100:40 to 100:100.

Claims

1. An airbag module comprising:

a module cover;

an airbag configured to inflate in an event of a vehicle emergency; and

an inflator configured to provide gas for inflating the airbag,

wherein the inflator and the airbag are connected to a retainer,

wherein the module cover and the retainer are connected to form an enclosure volume, and

wherein a ratio of the enclosure volume to a portion of the enclosure volume that is occupied by components of the airbag module is 100;

40 to 100;

100.

2. The airbag module of claim 1, further comprising a displacement member disposed within the enclosure volume.

3. The airbag module of claim 2, wherein the displacement member comprises metal.

4. The airbag module of claim 2, wherein the displacement member comprises a polymer.

5. The airbag module of claim 2, wherein the displacement member comprises wire mesh.

6. The airbag module of claim 2, wherein the displacement member is connected to an inner surface of the airbag module.

7. The airbag module of claim 2, wherein the displacement member is formed integrally with the module cover.

8. The airbag module of claim 2, wherein the displacement member is connected to the retainer.

9. The airbag module of claim 2, wherein the displacement member is formed integrally with the retainer.

10. The airbag module of claim 2, wherein the displacement member includes a hollow portion and is configured to be attached to an inner surface of the airbag module.

11. The airbag module of claim 10, wherein the displacement member includes at least one opening.

12. The airbag module of claim 11, wherein the opening comprises a through hole.

13. An airbag device for protecting an occupant of a vehicle, comprising:

an airbag module including an airbag, an inflator for inflating the airbag, and a retainer,

wherein the airbag and the inflator are disposed within an enclosed portion of the module, and

wherein a volume of unoccupied space within the enclosed portion of the module is no greater than 60 percent of a volume of the enclosed portion of the module.

14. An airbag device for protecting an occupant of a vehicle, comprising:

an airbag module including an airbag, an inflator for inflating the airbag, and a retainer,

wherein the airbag and the inflator are disposed within an enclosed portion of the module, and

wherein a ratio of a volume of the enclosed portion of the module to a volume occupied by the airbag and the inflator is 100;

40 to 100;

100.
