Abstract

A protective device may be configured to be worn to protect a portion of a wearer's anatomy. A pliable first material may form a perimeter portion and at least one connecting portion. A rigid second material may form at least two plates retained within the perimeter portion and at least one connecting portion.

First claim

What is claimed is:

1. A protective device for attenuating force from an impact, the protective device comprising:
an impact plate comprising:
a first plate portion having an anterior surface, a posterior surface, and a first thickness between the anterior surface and the posterior surface of the first plate portion;
a second plate portion having an anterior surface, a posterior surface, and a second thickness between the anterior surface and the posterior surface of the second plate portion; and
a connecting tab that extends between and bridges the first plate and the second plate, the connecting tab having an anterior surface, a posterior surface, and a third thickness between the anterior surface and the posterior surface of the connecting tab, the third thickness being less than the first thickness and the second thickness; and

an elastomeric member that is more pliable than the impact shell and that includes a connecting portion that covers the anterior surface of the connecting tab.

2. The protective device of claim 1 , further comprising a plurality of connecting tabs integrally formed of a same material as the first plate portion and the second plate portion, the plurality of connecting tabs extending between the first plate portion and the second plate portion.

3. The protective device of claim 1 , wherein the first plate portion and the second plate portion each includes a plurality of ridges and a plurality of valleys extending in a substantially parallel fashion.

4. The protective device of claim 3 wherein the protective device has a convex outward face and wherein more than fifty percent of the convex outward face includes the impact plate.

5. The protective device of claim 4 wherein the elastomeric member is constructed of a thermoplastic elastomer.

6. The protective device of claim 4 wherein the elastomeric member is constructed of a thermoplastic polyurethane.

7. The protective device of claim 4 wherein the elastomeric member is constructed of a rubber.

8. The protective device of claim 4 wherein the impact plate is constructed of a nylon.

9. The protective device of claim 4 wherein the impact plate is constructed of acrylonite butadiene styrene.

10. The protective device of claim 4 wherein the impact plate is constructed of polypropylene.

11. A protective device for attenuating force from an impact, the device comprising:
at least two plate portions including a first plate portion and a second plate portion, the at least two plate portions formed of a first material;
one or more connecting tabs that connects the first plate portion to the second plate portion;
an elastomeric perimeter portion that binds terminal edges of the at least two plate portions and forms a terminal perimeter edge of the protective device, the elastomeric perimeter portion formed of a second material that is more pliable than the first material; and
at least one elastomeric connecting portion extending between two points on the elastomeric perimeter portion, the elastomeric connecting portion covering at least a portion of the connecting tab, the elastomeric connecting portion formed from the first material.

12. The protective device of claim 11 , wherein the at least one elastomeric connecting portion comprises a plurality of connecting portions.

13. The protective device of claim 11 , wherein the at least one elastomeric connecting portion extends horizontally in an as worn position.

14. The protective device of claim 11 , wherein the at least one elastomeric connecting portion extends vertically in an as worn position.

15. The protective device of claim 11 , wherein the at least one elastomeric connecting portion extends diagonally in an as worn position.

16. The protective device of claim 11 wherein the second material comprises at least one of a thermoplastic elastomer, a thermoplastic polyurethane, and a rubber.

17. The protective device of claim 16 wherein the first material comprises at least one of a nylon, acrylonite butadiene, and polypropylene.

18. The protective device of claim 17 wherein the first material and the second material have been fabricated by molding to have a complex three dimensional shape that is configured to conform to the portion of the wearer's anatomy to be protected.

19. The protective device of claim 11 wherein the first material and the second material have been fabricated by an additive manufacturing process to have a complex three dimensional shape that is configured to conform to the portion of the wearer's anatomy to be protected.
