Abstract

An airbag module includes an airbag and an inflator. The inflator is configured to have an output in the range of 180 to 320 kPa. The airbag is configured to have an inflation volume in the range of 50 to 95 L. The airbag can be a passenger-side, two chamber type airbag. The inflator can be a driver-side type inflator, such as a disc inflator. The airbag can include a membrane attached to at least one of the two chambers.

Claims

1. An airbag module, comprising:

an airbag; and

an inflator configured to have an output of 180 to 320 kPa,

wherein the airbag is configured to have an inflation volume in the range of 50 to 95 L.

2. The airbag module of claim 1, wherein the airbag includes two butterfly fabric panels.

3. The airbag module of claim 2, wherein the two butterfly fabric panels are connected by a main seam extending along a periphery of the two fabric panels.

4. The airbag module of claim 1, wherein the airbag comprises a two chamber twin airbag.

5. The airbag module of claim 4, wherein the airbag includes a membrane connected to each of the two chambers of the airbag in the front of the airbag facing an occupant.

6. The airbag module of claim 4, wherein at least one of the two chambers of the airbag includes a membrane.

7. The airbag module of claim 4, wherein the two chamber twin airbag includes two fabric panels.

8. The airbag module of claim 7, wherein each of the twin chambers includes a vent hole positioned across the chamber from a connection point between the twin chambers.

9. The airbag module of claim 1, wherein the airbag is a passenger airbag.

10. The airbag module of claim 1, wherein the inflator is a disc inflator.

11. The airbag module of claim 1, wherein the airbag is configured to have an inflation volume in the range of 55 to 90 L.

12. The airbag module of claim 1, wherein the airbag is configured to have an inflation volume in the range of 65 to 75 L.

13. The airbag module of claim 1, wherein the airbag is configured to have an inflation volume in the range of 70 to 85 L.

14. An airbag device, comprising:

an airbag; and

an inflator configured to inflate the airbag,

wherein the ratio between a real volume of the airbag and an effective volume for occupant restraint is in the range of 1;

1.2 and 1;

2.

15. The airbag device of claim 14, wherein the airbag includes two butterfly fabric panels.

16. The airbag device of claim 15, wherein the two butterfly fabric panels are connected by a main seam extending along a periphery of the two fabric panels.

17. The airbag device of claim 14, wherein the airbag comprises a two chamber twin airbag.

18. The airbag device of claim 17, wherein the airbag includes a membrane connected to each of the two chambers of the airbag in the front of the airbag facing an occupant.

19. The airbag device of claim 17, wherein at least one of the two chambers of the airbag includes a membrane.

20. The airbag device of claim 17, wherein the two chamber twin airbag includes two fabric panels.

21. The airbag device of claim 20, wherein each chamber includes a vent hole positioned across the chamber from a connection point between the twin chambers.
