INTEGRATED BALLISTIC HELMET AND GAS MASK

摘要

An integrated helmet and respirator system comprises a shell defining a helmet portion, the helmet portion being bounded by a peripheral edge. An annular shroud has an upper edge and a lower edge, the upper edge removably attached to the peripheral edge of the helmet portion and the lower edge attached to an annular frame member. A front portion of the annular shroud defines a visor. A one-way exhaust valve is received within an opening in the annular frame member. The one-way exhaust valve is configured to allow an exhalation gas exhaled by a user to exit an interior of the integrated helmet and respirator system and to prevent or minimize ambient air from entering the interior of the integrated helmet and respirator system. A neck dam extends downward from the frame and is configured to prevent or minimize ambient air from entering the interior of the integrated helmet and respirator system.
