Abstract

An airbag for protecting passengers in a car or the like. An airbag apparatus includes an airbag mounted in a side of a vehicle and a non-inflatable curtain that is mounted in the side of the vehicle. The non-inflatable curtain may be activated by inflation gas provided by an inflator for the airbag. The non-inflatable curtain may be arranged above the airbag prior to deployment of the airbag. The airbag may be positioned closer to an interior of a vehicle than the non-inflatable curtain.

Claims

1. An airbag apparatus, comprising;

an airbag configured to deploy along a side of a vehicle cabin; and

a non-inflatable curtain configured to deploy between the airbag and the side of the vehicle cabin.

2. The airbag apparatus as claimed in claim 1, further comprising a mechanism for deploying the non-inflatable curtain.

3. The airbag apparatus as claimed in claim 2, wherein the mechanism is activated by an inflator configured to provide inflation gas for the airbag.

4. The airbag apparatus as claimed in claim 3, wherein the mechanism is connected to the non-inflatable curtain by a wire.

5. The airbag apparatus as claimed in claim 4, wherein the mechanism includes a piston-cylinder actuator.

6. The airbag apparatus as claimed in claim 5, wherein the mechanism includes:

a spring;

a first plate arranged within a tube, wherein the first plate includes an aperture;

a stop attached to the spring;

a second plate connected to the piston-cylinder actuator, wherein the second plate has an aperture and the second plate is arranged so that the second plate slides in relation to the first plate so that the apertures of the first and second plates come into alignment and the stop may pass through the apertures; and

wherein the piston-cylinder actuator is arranged to activate the spring through movement of the second plate when the piston-cylinder actuator is activated.

7. The airbag apparatus as claimed in claim 5, further including:

a plurality of balls positioned in the cylinder and configured to be moved by gas provided by the inflator; and

a gear that is arranged in a path of movement of the balls so that the gear rotates due to the movement of the balls.

8. The airbag apparatus as claimed in claim 5, wherein the wire is connected to the piston and the non-inflatable curtain.

9. The airbag apparatus as claimed in claim 4, wherein the mechanism includes a wire that is connected to both the airbag and to the non-inflatable curtain.

10. The airbag apparatus as claimed in claim 9, wherein the apparatus is arranged so that the non-inflatable curtain moves in response to movement of the airbag.

11. The airbag apparatus as claimed in claim 9, wherein the wire passes through a one-way pulley.

12. The airbag apparatus as claimed in claim 3, wherein the apparatus is arranged so that the airbag deploys upwardly and the non-inflatable curtain deploys downward from above the airbag.

13. The airbag apparatus as claimed in claim 3, wherein the apparatus is arranged so that the airbag is positioned closer to the interior of the vehicle than the non-inflatable curtain.

14. The airbag apparatus as claimed in claim 13, wherein the non-inflatable curtain and airbag overlap one another.

15. The airbag apparatus as claimed in claim 3, wherein the airbag and non-inflatable curtain are arranged between two pillars of the vehicle before deployment and after deployment.

16. The airbag apparatus as claimed in claim 2, wherein the entire airbag apparatus is contained in a door module for a vehicle.

19. The airbag apparatus as claimed in claim 1S, wherein a mechanism for deploying the non-inflatable curtain is activated by an inflator configured to provide inflation gas for the airbag.

17. An airbag apparatus, comprising:

an airbag configured to deploy along a side of a vehicle cabin;

a non-inflatable curtain configured to deploy along the side of the vehicle cabin; and

wherein the apparatus is arranged so that the airbag deploys upwardly and the non-inflatable curtain deploys from above the airbag.

18. An airbag apparatus, comprising:

an airbag configured to deploy along a side of a vehicle cabin;

a non-inflatable curtain configured to deploy along the side of the vehicle cabin; and

wherein the apparatus is arranged so that the airbag deploys upwardly.

20. The airbag apparatus as claimed in claim 18, wherein the apparatus is arranged so that the airbag is positioned closer to the interior of the vehicle than the non-inflatable curtain.

21. The airbag apparatus as claimed in claim 18, wherein the airbag and non-inflatable curtain are arranged between two adjacent pillars of the vehicle before deployment and after deployment.

22. The airbag apparatus as claimed in claim 18, wherein the entire airbag apparatus is contained in a door module for a vehicle.

23. An airbag device including an airbag configured to deploy along a side of a vehicle cabin and a non-inflatable curtain configured to deploy between the airbag and the side of the vehicle cabin, wherein prior to deployment the curtain is stored above the airbag.

24. The airbag apparatus as claimed in claim 23, wherein a mechanism for deploying the non-inflatable curtain is activated by an airbag inflator configured to provide inflation gas for the airbag.
