摘要： Airflow is improved for multi-agent chemical biological air-purifying apparatus by providing a filter module that has multiple filter elements contained within a substantially sealed housing. The housing secures the filter elements in a spaced relation such that the top and bottom faces of each filter element are exposed to the flow of air and provides an air path within the housing adapted to channel air through the multiple filter elements in a parallel flow. The filter module may be made from a flexible and resilient plastic material and may be contoured to conform to the shape of a helmet liner or similar headgear.

摘要： The invention utilizes a chemical/biological hood with a filter-blower system that is attached to the chemical/biological hood. The filter-blower system provides overpressure to the hood only. The hood is fitted to or attached to a chemical/biological mask. Overpressure created by the filter-blower around the mask is created and is independent of the wearer's respiration so that over-breathing of the positive pressure is not possible. Typically this system would be available as a hood capable of providing enhanced protection. However, the filter-blower and hood system could be integrated with the mask. Cinching or sealing the hood at the neck can improve overpressure performance.

摘要： A modular helmet-mask assembly for protecting a user's head and face from hazards such as from chemical and biological warfare agents. The invention includes an impact resistant helmet; a face protection assembly, which can be attached and detached from the helmet; and a transparent, impact resistant lens. The face protection assembly includes an impact resistant face protection shell with a vision port, through which the transparent lens can be positioned; a flexible nosecup assembly positioned to engage the mouth and nose of the user, which also includes a breathe-through airflow assembly and filter unit; and a flexible face seal which surrounds the nosecup assembly and lens and engages the face of the user. An adjustable head harness is attached to the shell or face seal, for adjustably securing the face seal and nosecup to the user's face to maximize comfort and protection while preventing fogging of the lens.
