Abstract

An airbag fabric which has been coated with a polyamide coating, comprising a thermoplastic silicone vulcanizate. The coating may be adhered to the airbag fabric without the use of a primer and may be cured at room temperature. The coated airbag fabric may be reheated during fabrication and heat welded at the fabric boundary.

Claims (24)

1. An airbag fabric comprising:

a matrix of nylon yarns; and

a coating comprising a thermoplastic silicone vulcanizate,

wherein the thermoplastic silicone vulcanizate comprises silicone particles or powder dispersed in a thermoplastic binder.

2. The airbag fabric of claim 1 , wherein the coating is cured at room temperature when adhered to the matrix of nylon yarns.

3. The airbag fabric of claim 1 , wherein the nylon yarns coated with the coating may be reheated during fabrication; and

wherein the airbag fabric may be heat welded at a fabric boundary.

4. The airbag fabric of claim 1 , wherein the coating is self-sealing on the matrix of nylon yarns.

5. The airbag fabric of claim 1 , wherein the matrix of nylon yarns is coated with the coating by an extrusion coating process.

6. The airbag fabric of claim 1 , wherein the thermoplastic silicone vulcanizate may directly adhere to the nylon yarns without the use of a primer.

7. The airbag fabric of claim 1 , wherein the nylon yarns and the coating are both polyamides to increase adhesion of the coating to the nylon yarns.

8. The airbag fabric of claim 1 , wherein the coating comprises a liquid silicone rubber.

9. A method of coating an airbag fabric comprising the steps of:

applying a thermoplastic silicone vulcanizate coating directly onto a nylon airbag fabric, wherein the thermoplastic silicone vulcanizate coating comprises silicone particles or powder dispersed in a thermoplastic binder; and

curing the coating at room temperature.

10. The method of claim 9 , wherein the step of applying the coating does not include a use of a primer.

11. An airbag comprising:

an airbag fabric; and

a thermoplastic silicone vulcanizate coating covering the airbag fabrics,

wherein the thermoplastic silicone vulcanizate coating comprises silicone particles or powder dispersed in a thermoplastic binder.

12. The airbag according to claim 11 , wherein the airbag is configured to deploy along a side of a vehicle to protect an occupant of the vehicle during a vehicle rollover condition.

13. The airbag fabric of claim 1 , wherein the thermoplastic binder is polyamide, nylon, or polypropylene.

14. The method of claim 9 , wherein the thermoplastic binder is polyamide, nylon, or polypropylene.

15. The airbag according to claim 11 , wherein the thermoplastic binder is polyamide, nylon, or polypropylene.
