Abstract

An occupant side-impact protection apparatus for a motor vehicle comprising an inflatable cushion stored in a folded configuration and an inflator configured to provide gas to inflate the cushion. The cushion is configured to inflate to protect the occupant of a vehicle. The side-impact protection apparatus further includes a tether to provide tension to tailor the deployment trajectory of the cushion. The tether is coupled to the cushion at a first coupling location and a second coupling location and the distance along the tether from the first coupling location to the second coupling location is less than the distance along the cushion from the first coupling location to the second coupling location.

Claims

1. An occupant side-impact protection apparatus for a motor vehicle, the apparatus comprising:

an inflatable cushion stored in a folded configuration and deploys from a seat assembly within the motor vehicle;

an inflator configured to provide gas to inflate the cushion;

wherein the cushion is configured to inflate to protect an occupant of the vehicle; and

a tether to provide tension to tailor a deployment trajectory of the cushion;

wherein the tether is coupled to the cushion at a first coupling location and a second coupling location, the tether being disposed externally relative to the cushion;

wherein a distance along the tether from the first coupling location to the second coupling location is less than a distance along the cushion from the first coupling location to the second coupling location; and

wherein, upon deployment, one of the first and second coupling locations is located nearer to a seat back of the seat assembly than the other of the first and second coupling locations and the other of the first and second coupling locations is located at a forward location relative to the one of the first and second coupling locations in a vehicle longitudinal direction.

2. The protection apparatus of claim 1, wherein the cushion is configured to deploy from an outboard side of the seat assembly within the vehicle.

3. The protection apparatus of claim 1, wherein the cushion is configured to deploy from an inboard side of the seat assembly within the vehicle.

4. The protection apparatus of claim 1, wherein the tether is configured to couple to an external surface of the cushion.

5. The protection apparatus of claim 1, wherein the cushion includes at least one fold between the first coupling location and the second coupling location.

6. The protection apparatus of claim 1, wherein the cushion includes at least one crease between the first coupling location and the second coupling location.

7. The protection apparatus of claim 1, wherein the cushion includes at least one fold and at least one crease between the first coupling location and the second coupling location.

8. The protection apparatus of claim 1, wherein the first coupling location of the tether is located on a perimeter of the cushion and the second coupling location of the tether is located on a portion of the cushion away from the perimeter.

9. The protection apparatus of claim 1, wherein the second coupling location of the tether is located on a portion of the cushion away from a perimeter of the cushion.

10. The protection apparatus of claim 1, wherein the tether is disposed externally relative to a fillable volume of the cushion.

11. An occupant side-impact protection apparatus for a motor vehicle, the apparatus comprising:

an inflatable cushion stored in a folded configuration and deploys from a seat assembly within the motor vehicle;

an inflator configured to provide gas to inflate the cushion;

wherein the cushion is configured to inflate to protect an occupant of the vehicle; and

a tether to provide tension to tailor a deployment trajectory of the cushion,

wherein the tether is coupled to the cushion at a first coupling location and a second coupling location, the tether being disposed externally relative to the cushion;

wherein a distance along the tether from the first coupling location to the second coupling location is less than a distance along the cushion from the first coupling location to the second coupling location;

wherein both the first coupling location and the second coupling locations are located on a perimeter of the cushion; and

wherein, upon deployment, one of the first and second coupling locations is located nearer to a seat back of the seat assembly than the other of the first and second coupling locations and the other of the first and second coupling locations is located at a substantially forward location relative to the one of the first and second coupling locations in a vehicle longitudinal direction.

12. The protection apparatus of claim 11, wherein the cushion is configured to deploy from an outboard side of the seat assembly within the vehicle.

13. The protection apparatus of claim 11, wherein the cushion is configured to deploy from an inboard side of the seat assembly within the vehicle.

14. The protection apparatus of claim 11, wherein the tether further includes a shortening mechanism located between the first and second coupling locations and the shortening mechanism includes at least one fold and at least one stitch.

15. The protection apparatus of claim 14, wherein the stitch is configured to tear when the tether is subjected to a predetermined tension.

16. The protection apparatus of claim 11, wherein the tether is configured to couple to an external surface of the cushion.

17. The protection apparatus of claim 11, wherein the cushion includes at least one fold between the first coupling location and the second coupling location.

18. The protection apparatus of claim 11, wherein the cushion includes at least one crease between the first coupling location and the second coupling location.

19. The protection apparatus of claim 11, wherein the cushion includes at least one fold and at least one crease between the first coupling location and the second coupling location.

20. The protection apparatus of claim 11, wherein the tether is disposed externally relative to a fillable volume of the cushion.

21. An occupant side-impact protection apparatus for a motor vehicle, the apparatus comprising:
