Abstract

An airbag assembly for use within a vehicle, which includes an airbag; an inflator; and an airbag housing. The airbag housing includes a cavity for storing the airbag and is configured to be mounted in the vehicle. The cavity includes a plurality of fins, which are configured to direct inflation gas and to conduct heat from the inflation gas to the fins. The housing further includes a plurality of walls and a base that form a frame structure surrounding the cavity and an opening through which the airbag deploys into the vehicle. The airbag is configured to be deployed by inflation gas provided by the housing inflator, and configured to provide protection to an occupant. The inflator is mounted in and coupled to the housing.

Claims

1. An airbag assembly for use within a vehicle, comprising:

an airbag;

an inflator;

an airbag housing including a cavity for storing the airbag;

wherein the housing is configured to be mounted in the vehicle;

wherein the airbag is configured to be deployed by inflation gas provided by the housing inflator, and configured to provide protection to an occupant;

wherein the housing includes a plurality of walls and a base that form a frame structure surrounding the cavity and including an opening through which the airbag deploys into the vehicle;

wherein the inflator is mounted in and coupled to the housing; and

wherein the cavity includes a plurality of fins, which are configured to direct inflation gas and to conduct heat from the inflation gas to the fins.

2. The airbag assembly of claim 1, wherein the cavity of the housing is made from magnesium using a thixomolding process.

3. The airbag assembly of claim 1, wherein the housing includes a vent and a corresponding vent gate, wherein the vent gate is configured to be displaced by a displacing member from a first position to a second position.

4. The airbag assembly of claim 3, wherein the displacing member comprises a micro-gas generator.

5. The airbag assembly of claim 3, wherein the first position of the vent gate allows inflation gas to pass through the vent of the housing and the second position of the vent gate covers at least part of the vent of the housing, prohibiting at least a portion of the inflation gas from passing through the vent.

6. The airbag assembly of claim 3, wherein the inflation gas that passes through the vent of the housing inflates an inflatable protection device other than the airbag.

7. An airbag assembly for use within a vehicle, comprising:

an airbag;

an inflator;

an airbag housing including a cavity for storing the airbag;

wherein the housing is configured to be mounted in the vehicle;

wherein the airbag is configured to be deployed by inflation gas provided by the housing inflator, and configured to provide protection to an occupant;

wherein the housing includes a plurality of walls and a base that form a frame structure surrounding the cavity and including an opening through which the airbag deploys into the vehicle;

wherein the inflator is mounted in and coupled to the housing; and

wherein the housing further includes a vent and a corresponding vent gate, wherein the vent gate is configured to be displaced by a displacing member from a first position to a second position.

8. The airbag assembly of claim 7, wherein the displacing member comprises a micro-gas generator.

9. The airbag assembly of claim 7, wherein the first position of the vent gate allows inflation gas to pass through the vent of the housing and the second position of the vent gate covers at least part of the vent of the housing, prohibiting at least a portion of the inflation gas from passing through the vent.

10. The airbag assembly of claim 7, wherein the inflation gas that passes through the vent of the housing inflates an inflatable protection device other than the airbag.

11. The airbag assembly of claim 7, wherein the housing is made from glass fiber reinforced polymer using a molding process.

12. The airbag assembly of claim 7, wherein the housing is made from magnesium using a thixomolding process.
