Helmets and vests
View Patent ↗Disclosed is an assembly which can include a hardened outer shell and an inner surface comprising a polymeric gel. The polymeric gel is enclosed within an envelope having opposed layers and is attached to the outer hardened surface cover. The hardened outer surface cover may be comprised of most any material known within the art. The sporting or shooting vest comprises a garment including gel-filled pockets or envelopes whereby impact can be absorbed and dissipated. Additionally, the outer layer of the shooting vest may be comprised of a Kevlar material wherein the vest would become a ballistic vest.
1. A shock absorbing sporting or shooting vest comprising;
a sleeveless vest for covering the upper body of a wearer including an outer shell and a gel filled envelope connected to the outer shell whereby impact can be absorbed and dissipated; and
wherein the gel filled envelope comprises a first layer, a second layer opposing the first layer, and a shock attenuating, polymer gel residing between the first and second opposed layers, and
wherein the shock attenuating polymer gel includes polymeric material that comprises at least greater than 50% by weight of an epoxidized vegetable oil, a thermoplastic polymer; and a prepolymer.
2. The vest of claim 1 , wherein the prepolymer comprises at least one of an isocyanate or an isocyanate monomer, or both.
3. The vest of claim 2 , wherein the thermoplastic polymer includes a hydroxy functional thermoplastic elastomer.
4. The vest of claim 2 , wherein the thermoplastic polymer includes a polybutadiene.
5. The vest of claim 3 , wherein the shock attenuating polymer gel comprises an activator that includes an alkyl tin compound, wherein the epoxidized vegetable oil is selected from the group consisting of soybean oil, linseed oil, and combinations thereof, and wherein the thermoplastic polymer comprises a polydiene.
6. The vest of claim 5 , wherein the thermoplastic polymer is substantially free of a polyurethane.
7. The vest of claim 5 , wherein the first layer and the second layer are fused together to enclose the shock attenuating, polymer gel.
8. The vest of claim 7 , wherein the first layer and the second layer are fused together to form a plurality of envelopes to encompass the shock attenuating, polymer gel.
9. The vest of claim 1 , wherein the shock attenuating polymer gel comprises an activator.
10. The vest of claim 9 , wherein the activator is an alkyl tin compound.
11. The vest of claim 1 , wherein the epoxidized vegetable oil is selected from the group consisting of soybean oil, linseed oil, and combinations thereof.
12. The vest of claim 1 , wherein the thermoplastic polymer comprises a polydiene.
13. The vest of claim 1 , wherein the thermoplastic polymer is a polybutadiene.
14. The vest of claim 1 , wherein the prepolymer comprises at least one of an isocyanate or an isocyanate monomer, or both.
15. The vest of claim 14 , wherein the thermoplastic polymer includes a hydroxy functional thermoplastic elastomer.
16. The vest of claim 15 , wherein the shock attenuating polymer gel comprises an activator that includes an alkyl tin compound, wherein the epoxidized vegetable oil is selected from the group consisting of soybean oil, linseed oil, and combinations thereof, and wherein the thermoplastic polymer comprises a polydiene.
17. The vest of claim 16 , wherein the thermoplastic polymer is substantially free of a polyurethane.
18. The vest of claim 16 , wherein the first layer and the second layer are fused together to enclose the shock attenuating, polymer gel.
19. A shock attenuating vest comprising;
a sleeveless vest for covering the upper body of a wearer including an outer shell, a ballistics layer connected to the outer shell, an inner surface and a pocket connected to one of the outer shell, the ballistics layer and the inner surface;
a gel-filled envelope positioned in the pocket, the gel-filled envelope to attenuate and dissipate forces thereon; and
wherein the gel filled envelope comprises a first layer, a second layer opposing the first layer, and a shock attenuating, polymer gel residing between the first and second opposed layers, and wherein the shock attenuating polymer gel includes polymeric material that comprises at least greater than 50% by weight of an epoxidized vegetable oil, a thermoplastic polymer; and a prepolymer.
20. The vest of claim 19 , wherein the pocket is beneath the outer shell.
