A headpiece assembly for use with a night vision mounting arm includes a bump shell and an interior suspension assembly for seating on the head of a human. A mounting bracket is secured to the front of the bump shell for removably attaching the night vision mounting arm to the bump shell. A ballistic shell has a bottom forming an opening and a coupling mechanism for removably securing the ballistic shell to the bump shell when the ballistic shell is placed over the bump shell. The ballistic shell has a front and a notch extending upwardly from the opening into the front for receiving the mounting bracket when the ballistic shell is placed over the bump shell so as to permit the night vision mounting arm to be attached to the bump shell during use of the ballistic shell.
摘要:
A face protector comprises a protective structure shaped for extending about a person's mandibular region and a mounting for mounting the face protector to a military combat helmet. The protective structure comprises a front portion and opposed left and right side portions extending from the front portion, the front portion having a free upper edge for positioning below eye level and above mouth level when mounted to the helmet, and being size to extend to below a person's chin. The front portion has inner and outer surfaces, and the mounting is positioned to space the inner surface and the upper edge away from the person's mouth and nose when mounted to the helmet to provide a gap for the passage of ambient air therebetween to permit unobstructed breathing. The protective structure comprises a ballistic resistant material for providing protection against high velocity fragments from explosive devices.

A cooling cushion for use in military ACH helmets is described. The cooling cushion comprises a plurality of chambers each containing water absorbent polymer crystals.
摘要:
Armor for a helmet includes a soft-armor attachment and a hard-armor attachment. The soft-armor attachment encases a flexible soft-armor anti-ballistic member within its interior, and detachably mounts to the helmet exterior using one or more fasteners. The hard-armor attachment encases one or more hard-armor members within its interior, and detachably mounts to the soft-armor attachment using one or more fasteners. When both the soft-armor attachment and the hard-armor attachment are in the mounted position, the soft-armor attachment is disposed between the helmet exterior and the hard-armor attachment.
