Modular helmet-mask

Offers better and more comfortable protection of a user's head and face from hazards such as chemical and biological warfare agents

Military Technology Environmental

To highlight a few features, the two-part design offers complete enclosure of the nose and mouth 33, adjustment by rotating the knob 23, and full face enclosure by the shield 40.

Protective masks are currently used by the military and civilian entities for protection against chemical and biological contaminants. However, such masks often impose a substantial physiological burden on the wearer. These masks are typically difficult to wear for prolonged periods because they are relatively bulky and heavy, have high breathing resistance, impair vision and communications, cause thermal stress, physical discomfort, and degrade job performance. Furthermore, the demands placed on such protective masks for use by the crews of military vehicles, such as land and sea vehicles and aircraft, are even greater due to the limitations on the size or bulk of such masks in crowded spaces, the need to avoid fogging of the lenses, and wearer exhaustion from heat buildup, physical discomfort, and respiratory effort.

An improvement over the current design is offered by Army scientists and engineers in a modular helmet-mask assembly which includes a helmet, a face protection assembly, and a transparent, impact resistant lens. The face protection assembly, which can be attached and detached from the helmet, includes a  shell which is made of an impact resistant material, for protecting the head and face of the user. The face protection assembly includes a flexible nose cup assembly within the shell and flexible face seal on an inner surface of the shell. The nose cup is positioned to fully engage the mouth and nose of the user, and it includes a breathe-through airflow assembly and filter unit. A strap is attached to the shell or face seal, for adjustably securing the face seal and nose cup to the user’s face to maximize comfort and protection while preventing fogging of the lens.

This design could offer an improvement over the Army M42, M45, M48, M49 masks as well as the Air Force AERP mask system.
