Abstract

An occupant restraint system for a motor vehicle having a seat system configured to provide seating to an occupant positioned adjacent to a console having a top surface and configured to provide utility; which includes a cushion stored in the folded configuration and having an inflatable chamber configured to inflate adjacent to an occupant to provide impact restraint to the occupant; an inflator configured to provide gas to inflate the inflatable chamber of the cushion; wherein a bottom portion of the cushion deploys to a position below the top surface of the console and a top portion of the cushion deploys to a position above the top surface of the console; wherein, during occupant loading, a portion of cushion contacts the console to receive lateral support and to react the forces imparted into the cushion induced by the occupant impacting the cushion, wherein the lateral support impedes lateral displacement of the cushion providing additional restraint to the occupant.

wherein such lateral support impedes lateral displacement of the cushion providing additional restraint to the occupant.

2. The restraint system of claim 1, wherein the bottom portion of the cushion that deploys to the position below the top surface of the console includes at least a portion of the inflatable chamber.

3. The restraint system of claim 1, wherein the inflatable chamber includes a lower portion having a downwardly narrowing tapered thickness during deployment.

4. An occupant restraint system for a motor vehicle having a seat system configured to provide seating to an occupant positioned adjacent to a console having a top surface and configured to provide utility, the restraint system comprising:

a cushion stored in the folded configuration;

wherein the cushion includes an inflatable chamber, which is configured to inflate adjacent to an occupant to provide impact restraint to the occupant;

an inflator configured to provide gas to inflate the inflatable chamber of the cushion;

wherein a bottom portion of the cushion deploys to a position below the top surface of the console, and a top portion of the cushion deploys to a position above the top surface of the console;

wherein, during occupant loading of the cushion, a portion of the cushion contacts the console to receive lateral support and to react the forces imparted into the cushion induced by the occupant impacting the cushion;

wherein such lateral support impedes lateral displacement of the cushion providing additional restraint to the occupant; and

a second inflatable chamber configured having a smaller inflatable volume relative to the inflatable volume of the first inflatable chamber of the cushion, wherein the second inflatable chamber reacts forces between the first inflatable chamber and the console during airbag deployment.

5. The restraint system of claim 4, wherein the first and second inflatable chambers are separated by a dividing layer of fabric, which prohibits fluid from moving directly between the two chambers.

6. An occupant restraint system for a motor vehicle having a seat system configured to provide seating to an occupant positioned adjacent to a console having a top surface and configured to provide utility, the restraint system comprising:

a cushion stored in the folded configuration;

wherein the cushion includes an inflatable chamber, which is configured to inflate adjacent to an occupant to provide impact restraint to the occupant;

an inflator configured to provide gas to inflate the inflatable chamber of the cushion;

wherein a bottom portion of the cushion deploys to a position below the top surface of the console, and a top portion of the cushion deploys to a position above the top surface of the console;

wherein, during occupant loading of the cushion, a portion of the cushion contacts the console to receive lateral support and to react the forces imparted into the cushion induced by the occupant impacting the cushion;

wherein such lateral support impedes lateral displacement of the cushion providing additional restraint to the occupant; and

a positioning mechanism having a first end coupled to the cushion and a second anchored end, wherein the bottom portion of the cushion that deploys to the position below the top surface of the console includes at least a portion of the positioning mechanism.

7. The restraint system of claim 6, wherein the bottom portion of the cushion that deploys to the position below the top surface of the console includes at least a portion of the inflatable chamber.

8. The restraint system of claim 6, wherein the inflatable chamber includes a bottom surface configured to deploy to a position above the top surface of the console.

9. The restraint system of claim 6, wherein during occupant loading of the cushion, at least a portion of the positioning mechanism contacts the console to receive lateral support and to react the forces imparted into the cushion by the occupant impacting the cushion.

10. The restraint system of claim 6, wherein the positioning mechanism configuration is selected from the group consisting of sail-panel shaped, strap-shaped, and tapered.

11. The restraint system of claim 6, wherein the anchored end of the positioning mechanism is coupled to a device that is selected from the group consisting of seat system, the console, a seatbelt system, and a floor member of the vehicle.

12. The restraint system of claim 6, wherein the anchored end of the positioning mechanism is slideably coupled to allow the anchored end to displace during airbag deployment.

13. The restraint system of claim 6, wherein the positioning mechanism includes a selvage portion stiffened by having a plurality of layers of fabric coupled together.

14. The restraint system of claim 6, wherein the positioning mechanism routes from one side of the cushion to a different side of the cushion to decrease the effective length of the mechanism during airbag deployment.

15. The restraint system of claim 6, wherein the positioning mechanism routes through a slot in a non-inflated portion of the cushion.

16. The restraint system of claim 6, wherein the anchored end of the positioning mechanism is coupled to at least a portion of the cushion, wherein the portion is selected from the group consisting of a selvage portion, an inflated portion, and a non-inflated portion.

17. The restraint system of claim 6, wherein the positioning mechanism deploys through the exterior surface of the seat system, as the positioning mechanism moves from a stored configuration to a deployed configuration.

18. An occupant restraint system for a motor vehicle having a seat system configured to provide seating to an occupant positioned adjacent to a console having a top surface and configured to provide utility, the restraint system comprising:

a cushion stored in the folded configuration;
