An airbag is disclosed that comprises a first fabric layer, a second fabric layer, and an adhesive. The first and second fabric layers are coated with silicone elastomer coatings. The adhesive is a heat-cured silicone adhesive, and forms a seam-bond between the first and second layers such that a bag-like structure is created.
1. An airbag comprising:
a first fabric layer coated with a first silicone elastomer coating;
a second fabric layer coated with a second silicone elastomer coating; and
a heat-cured silicone adhesive, wherein the heat-cured silicone adhesive forms a seam-bond between the first and second layers such that a bag-like structure is created,
wherein the bag-like structure is configured to be a curtain airbag with a non-sewn periphery.
2. The airbag according to claim 1 , wherein the heat-cured silicone adhesive directly adheres to the first coated fabric layer and the second coated fabric layer.
3. The airbag according to claim 1 , wherein the heat-cured silicone adhesive has sufficient strength such that the bag-like structure does not rupture upon deployment of the airbag in an event of a crash.
4. The airbag according to claim 1 , wherein the first and second coated fabric layers are solely attached to each other by the heat-cured silicon adhesive.
5. The airbag according to claim 1 , wherein the heat-cured silicone adhesive comprises is an addition-cure type with a platinum hydrosilation chemistry.
6. The airbag according to claim 1 , wherein adhesive strength of the seam-bond is between 96 lbs min. and 120 lbs. min.
7. The airbag according to claim 1 , where the heat-cured silicone adhesive is an elevated temperature accelerated cure silicon adhesive.
8. The airbag according to claim 1 , where the heat-cured silicon adhesive is configured to be cured between 50 and 190° C.
9. An occupant safety module, comprising:
a gas inflator; and
a curtain airbag in fluid communication with the gas inflator, wherein the curtain airbag comprises:
a first fabric layer coated with a first silicone elastomer coating;
a second fabric layer coated with a second silicone elastomer coating; and
a heat-cured silicone adhesive,
wherein the heat-cured silicone adhesive forms a seam-bond between the first and second layers such that a bag-like structure is created,
wherein the curtain airbag has a non-sewn periphery.
10. The occupant safety module according to claim 9 , wherein the heat-cured silicone adhesive has sufficient strength such that the bag-like structure does not rupture upon deployment of the airbag in an event of a crash.
11. The occupant safety module according to claim 9 , wherein the first and second coated fabric layers are solely attached to each other by the heat-cured silicon adhesive.
12. The occupant safety module according to claim 9 , wherein the heat-cured silicone adhesive is an addition-cure type with a platinum hydrosilation chemistry.
13. The occupant safety module according to claim 9 , wherein adhesive strength of the seam-bond is between 96 lbs min. and 120 lbs. min.
14. The occupant safety module according to claim 9 , where the heat-cured silicone adhesive is an elevated temperature accelerated cure silicon adhesive.
15. The occupant safety module according to claim 9 , where the heat-cured silicon adhesive is configured to be cured between 50 and 190° C.
