Abstract

A vehicle seat belt system is provided. The vehicle seat belt system includes a seat belt comprising a tubular seat belt webbing defining a passageway and a plurality of exhaust openings. The seat belt system also has an air porous compressible material disposed within the passageway. The seat belt buckle has an air delivery device that supplies air to the seat belt, wherein the air porous compressible material allows air to flow through the passageway when compressed.

Claims

1. A vehicle seat belt system comprising:

a seat belt comprising a tubular seat belt webbing defining a passageway and a plurality of exhaust openings;

an air porous compressible material disposed within the passageway; and

an air delivery device supplying air to the seat belt, wherein the air porous compressible material allows air to flow through the passageway when compressed.

2. The seat belt system of claim 1, wherein the air porous compressible material comprises openings having a size in the range of 100 square microns to 10 square centimeters.

3. The seat belt system of claim 1, wherein the air porous compressible material comprises a lattice structure.

4. The seat belt system of claim 1, wherein the air porous compressible material comprises a rubber foam material.

5. The seat belt system of claim 1, wherein the seat belt comprises a shoulder belt, wherein the passageway, the plurality of exhaust openings and the air porous compressible material are formed in the shoulder belt.

6. The seat belt system of claim 1 further comprising a buckle for connecting with the seat belt webbing, wherein air from the air delivery device enters the webbing through the buckle.

7. The seat belt system of claim 1, wherein the air porous compressible material comprises at least one of polyurethane, polycarbonate, polycarbonate alloys, ethyl vinyl acetate, polypropylene, polyethylene, polyvinylidene fluoride, polytetrafluoroethylene (PTFE), nylon webbing, polymer fibers (PE/PET), highly compressed polymer fibers, origami folded smart polymers, nanocapsules, aerogel, and naturally porous fibers.

8. A vehicle seat belt system comprising:

a seat belt comprising a tubular seat belt webbing defining a passageway and a plurality of exhaust openings;

an air porous compressible material disposed within the passageway; and

an air delivery device supplying air to the seat belt, wherein the air porous compressible material maintains an opening in the passageway to allow air to flow through the passageway when compressed.

9. The seat belt system of claim 8, wherein the air porous compressible material comprises openings having a size in the range of 100 square microns to 10 square centimeters.

10. The seat belt system of claim 8, wherein the air porous compressible material comprises a lattice structure.

11. The seat belt system of claim 8, wherein the air porous compressible material comprises a rubber foam material.

12. The seat belt system of claim 8, wherein the seat belt comprises a shoulder belt, wherein the passageway, the exhaust openings and the air porous compressible material are formed in the shoulder belt.

13. The seat belt system of claim 8 further comprising a buckle for connecting with the seat belt webbing, wherein air from the air delivery device enters the webbing through the buckle.

14. The seat belt system of claim 8, wherein the air porous compressible material comprises at least one of polyurethane, polycarbonate, polycarbonate alloys, ethyl vinyl acetate, polypropylene, polyethylene, polyvinylidene fluoride, polytetrafluoroethylene (PTFE), nylon webbing, polymer fibers (PE/PET), highly compressed polymer fibers, origami folded smart polymers, nanocapsules, aerogel, and naturally porous fibers.
