Abstract

A protective helmet having a liner assembly received in an outer shell and connected to the outer shell, with front, rear, side and top portions each including at least one zone where the liner assembly includes a plurality of overlapping layers, each of the layers being made from one of first, second, third and fourth materials, where the first material has a greater density and/or hardness than that of the second, third and fourth materials, the second material has a greater density and/or hardness than that of the third and fourth materials, and the third material has a greater density and/or hardness than that of the fourth material, and wherein the liner assembly includes one or more particular zones set forth in Table 3 or 4.

Claims

1. A protective helmet comprising:

wherein each of the front, rear, side and top portions includes at least one zone where the liner assembly includes a plurality of overlapping layers, each of the layers being made from one of first, second, third and fourth materials, where the first material has a greater density than that of the second, third and fourth materials, the second material has a greater density than that of the third and fourth materials, and the third material has a greater density than that of the fourth material, and;

the at least one zone of the front portion includes at least one of the zones F1, F2 and F3 where the layers are made of the material set forth in Table 4 and have a respective thickness of at least the thickness set forth in Table 4;

the at least one zone of the rear portion includes at least one of the zones R1 and R2 where the layers are made of the material and have a respective thickness of at least the thickness set forth in Table 4;

the at least one zone of the side portions include at least one of the zones S1 and S2 where the layers are made of the material and have a respective thickness of at least the thickness set forth in Table 4; and

the at least one zone of the top portion includes at least one of the zones T1 and T2 where the layers are made of the material and have a respective thickness of at least the thickness set forth in Table 4.

2. The protective helmet as defined in claim 1, wherein the front portion includes all of the zones F1, F2 and F3 set forth in Table 4.

3. The protective helmet as defined in claim 1, wherein the rear portion includes the zones R1 and R2 set forth in Table 4.

4. The protective helmet as defined in claim 1, wherein the side portions include the zones S1 and S2 set forth in Table 4.

5. The protective helmet as defined in claim 1, wherein the top portion includes the zones T1 and T2 set forth in Table 4.

6. The protective helmet as defined in claim 1, wherein the respective thickness of each of the layers of the at least one of the zones F1, F2 and F3, of the at least one of the zones R1 and R2, of the at least one of the zones S1 and S2 and of the at least one of the zones T1 and T2 corresponds to at least the thickness forth in Table 3.

7. The protective helmet as defined in claim 1, wherein the first material has a greater hardness than that of the second, third and fourth materials, the second material has a greater hardness than that of the third and fourth materials, and the third material has a greater hardness than that of the fourth material.

8. The protective helmet as defined in claim 1, wherein the first, second, third and fourth materials correspond to the type of material set forth in Table 2.

9. The protective helmet as defined in claim 1, wherein, the density of each of the first, second, third and fourth materials is within the respective density range set forth in Table 2.

10. The protective helmet as defined in claim 1, wherein the hardness of each of the first, second, third and fourth materials is within the respective hardness range set forth in Table 2.

11. A protective helmet comprising:

an outer shell;

a liner assembly received in the outer shell and connected to the outer shell, the liner assembly having at least one zone where the liner assembly includes a plurality of overlapping layers, each of the layers being made from one of first, second, third and fourth materials, where the first material has a greater density than that of the second, third and fourth materials, the second material has a greater density than that of the third and fourth materials, and the third material has a greater density than that of the fourth material, and wherein the at least one zone includes at least one of the zones F1, F2, F3, R1, R2, S1, S2, T1 and T2 where the layers are made of the material and have a respective thickness of at least the thickness set forth in Table 4.

12. The protective helmet as defined in claim 11, wherein the liner assembly includes all of the zones F1, F2, F3, R1, R2, S1, S2, T1 and T2 set forth in Table 4.
