Abstract

An airbag device with a curtain airbag mounted along the roof line of the vehicle and a cascade type inflator. The inflator is divided into sections and positioned along the length of the airbag. The divided inflator eliminates the need to bend or contort the inflator when installed in a vehicle. Deployment of the airbag is controlled by a controller.

Claims

1. An airbag device, comprising:

a curtain airbag configured to deploy along an interior side of a vehicle and an inflator;

wherein the inflator includes a plurality of separate cascade inflators positioned along a length of the airbag.

2. The airbag device according to claim 1, further comprising a controller that controls the deployment of the airbag.

3. The airbag device of claim 2, wherein the controller sends a separate initiation signal to each cascade inflator.

4. The airbag device according to claim 1, wherein the airbag device is mounted along the roof line of a vehicle.

5. The airbag device according to claim 1, wherein each of the cascade inflators are linear.

6. An airbag device, comprising:

a plurality of airbags and a corresponding number of inflators, wherein each inflator is a cascade inflator and is positioned to inflate one of the plurality of airbags.

7. The airbag device according to claim 6, further comprising a connecting strip connects each of the plurality of airbags to another one of the plurality of airbags.

8. The airbag device according to claim 6, wherein the airbag device is mounted along the roof line of a vehicle.

9. The airbag device according to claim 6, further comprising a controller that controls the deployment of each of the airbags.

10. The airbag device of claim 9, wherein the controller sends a separate signal to each of the plurality of inflators in order to initiate inflation of each airbag.

11. The airbag device of claim 6, wherein the airbag device is mounted in a side of a seat in a vehicle.

12. An airbag device, comprising:

a seat-mounted airbag configured to deploy along a side of a seat; and

an inflator,

wherein the inflator includes a plurality of separate cascade inflators positioned along a length of the airbag.

13. The airbag device according to claim 12, further comprising a controller that controls the deployment of the airbag.

14. The airbag device of claim 13, wherein the controller sends a separate initiation signal to each cascade inflator.

15. The airbag device according to claim 12, wherein each of the cascade inflators are linear.
