Abstract

A vehicle airbag assembly, method of deployment and manufacture. The airbag assembly includes at least one inflatable portion and at least one non-inflatable portion. At least one mass is operably attached to the non-inflatable portion. Upon inflation of the inflatable portion, the mass provides a substantial tautness to the non-inflatable portion. The deployment method includes providing at least one inflatable portion and at least one non-inflatable portion. The airbag assembly is operably attached to the vehicle. A mass operably attached to the non-inflatable portion is provided. The inflatable portion is inflated. The non-inflatable portion of the airbag is extended substantially taut upon inflation of the inflatable portion with the mass. The manufacturing method includes forming at least one inflatable portion and at least one non-inflatable portion. At least one mass is operably attached to the non-inflatable portion. The mass is adapted to provide a substantial tautness to the non-inflatable portion during airbag assembly deployment.

Claims

1. An airbag assembly for a vehicle, the assembly comprising:

at least one inflatable portion of an airbag of the airbag assembly;

at least one non-inflatable portion of the airbag including at least one mass comprised of a resilient material and operably attached thereto;

wherein upon inflation of the at least one inflatable portion, the mass provides a substantial tautness to the at least one non-inflatable portion.

2. The assembly of claim 1 wherein the at least one mass is positioned adjacent an end portion of the at least one inflatable portion.

3. The assembly of claim 1 wherein the at least one mass is non-inflatable.

4. The assembly of claim 1 wherein the at least one mass comprises a cylindrical member.

5. The assembly of claim 1 wherein the at least one mass is positioned within an aperture formed within the at least one non-inflatable portion.

6. The assembly of claim 1 wherein the airbag assembly comprises a side-curtain airbag.

7. The assembly of claim 1 wherein the at least one non-inflatable portion is adapted to be positioned upon the inflation adjacent a “

B”

-Post portion of the vehicle.

8. An airbag assembly for a vehicle, the assembly comprising:

at least one inflatable portion of an airbag of the airbag assembly;

at least one non-inflatable portion of the airbag including at least one mass operably attached thereto;

wherein the at least one mass is positioned within an aperture comprising a flange portion formed within the at least one non-inflatable portion;

wherein upon inflation of the at least one inflatable portion, the mass provides a substantial tautness to the at least one non-inflatable portion.

9. A method of deploying an airbag assembly for a vehicle, the method comprising:

providing at least one inflatable portion of an airbag of the airbag assembly and at least one non-inflatable portion of the airbag, the airbag assembly adapted to be operably attached to the vehicle;

providing an aperture within a flange portion of the non-inflatable portion;

providing a mass positioned within the aperture;

inflating the at least one inflatable portion; and

extending the at least one non-inflatable portion of the airbag substantially taut upon inflation of the at least one inflatable portion with the mass.

10. The method of claim 9 wherein the mass is positioned adjacent an end portion of the non-inflatable portion.

11. The method of claim 9 wherein the airbag assembly is adapted to be deployed adjacent a side portion of the vehicle.

12. The method of claim 11 wherein the at least one non-inflatable portion is adapted to be deployed adjacent a “

B”

-Post portion of the vehicle.

13. A method of manufacturing an airbag assembly for a vehicle, the method comprising:

forming at least one inflatable portion of an airbag of the airbag assembly;

forming at least one non-inflatable portion of the airbag; and

operably attaching at least one mass comprised of a resilient material to the at least one non-inflatable portion;

wherein the mass is adapted to provide a substantial tautness to the at least one non-inflatable portion during deployment of the airbag assembly.

14. The method of claim 13 wherein operably attaching the at least one mass comprises positioning the at least one mass adjacent an end portion of the at least one non-inflatable portion.

15. The method of claim 13 wherein operably attaching at least one mass comprises forming an aperture within the at least one non-inflatable portion, and positioning the at least one mass substantially within said aperture.

16. A method of manufacturing an airbag assembly for a vehicle, the method comprising:

forming at least one inflatable portion of an airbag of the airbag assembly;

forming at least one non-inflatable portion of the airbag; and

operably attaching at least one mass to the at least one non-inflatable portion by forming an aperture within the at least one non-inflatable portion by operably attaching a flange portion of the at least one non-inflatable portion to another portion of the at least one non-inflatable portion;

wherein the mass is adapted to provide substantial tautness to the at least one non-inflatable portion during deployment of the airbag.

17. The method of claim 16 wherein operably attaching the flange portion to the at least one non-inflatable portion comprises an attachment method selected from a group consisting of sewing, bonding, and welding.
