1 . A protective helmet comprising: an outer shell; a liner assembly received in the outer shell and connected to the outer shell, the liner assembly defining a front portion configured to overlay a front of a head of a wearer, a rear portion configured to overlay a rear of the head of the wearer, a top portion configured to overlay a top of the head of the wearer, and two opposed side portions each configured to overlay a respective side of the head of the wearer; 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 F 1 , F 2 and F 3 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 R 1 and R 2 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 S 1 and S 2 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 T 1 and T 2 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 F 1 , F 2 and F 3 set forth in Table 4. 3 . The protective helmet as defined in claim 1 , wherein the rear portion includes the zones R 1 and R 2 set forth in Table 4. 4 . The protective helmet as defined in claim 1 , wherein the side portions include the zones S 1 and S 2 set forth in Table 4. 5 . The protective helmet as defined in claim 1 , wherein the top portion includes the zones T 1 and T 2 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 F 1 , F 2 and F 3 , of the at least one of the zones R 1 and R 2 , of the at least one of the zones S 1 and S 2 and of the at least one of the zones T 1 and T 2 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 F 1 , F 2 , F 3 , R 1 , R 2 , S 1 , S 2 , T 1 and T 2 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 F 1 , F 2 , F 3 , R 1 , R 2 , S 1 , S 2 , T 1 and T 2 set forth in Table 4. 13 . The protective helmet as defined in claim 11 , wherein the respective thickness of the layers of the at least one of the zones F 1 , F 2 , F 3 , R 1 , R 2 , S 1 , S 2 , T 1 and T 2 is at least the thickness set forth in Table 3. 14 . The protective helmet as defined in claim 11 , 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. 15 . The protective helmet as defined in claim 11 , wherein the first, second, third and fourth materials correspond to the type of material set forth in Table 2. 16 . The protective helmet as defined in claim 11 , wherein, the density of each of the first, second, third and fourth materials is within the respective density range set forth in Table 2. 17 . The protective helmet as defined in claim 11 , wherein the hardness of each of the first, second, third and fourth materials is within the respective hardness range set forth in Table 2. 18 . A protective helmet comprising: an outer shell; a liner assembly received in the outer shell and connected to the outer shell, the liner assembly defining a front portion configured to overlay a front of a head of a wearer, a rear portion configured to overlay a rear of the head of the wearer, a top portion configured to overlay a top of the head of the wearer, and two opposed side portions each configured to overlay a respective side of the head of the wearer; 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 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, and: the at least one zone of the front portion includes at least one of the zones F 1 , F 2 and F 3 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 rear portion includes at least one of the zones R 1 and R 2 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 S 1 and S 2 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 T 1 and T 2 where the layers are made of the material and have a respective thickness of at least the thickness set fo
