Abstract: A protective helmet including an outer shell, and 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 disposed above and out of contact with a top of the head of the wearer when the helmet is worn, and two opposed side portions each configured to overlay a respective side of the head of the wearer. Each of the front, rear, side and top portions includes at least one zone where the liner assembly includes a plurality of overlapping layers.

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.

Abstract: A protective helmet including a helmet body, a facemask extending from the front portion to cover at least a portion of a face of a wearer, and one or more adjustment mechanisms securing the facemask to the helmet body. The adjustment mechanism(s) is/are connected to the helmet, include(s) an engagement member engaged with the facemask, is/are selectively engageable with the facemask in at least two vertically spaced apart positions of the facemask relative to the helmet body, and allow(s) toolless adjustment between the vertically spaced apart positions. Adjustment mechanisms and methods of positioning a facemask are also discussed.
