Protective headgear system with filter protector

摘要

This invention is directed to a protective headgear system (10) which includes a relatively light weight, substantially rigid, headgear structure (100) which may include an internal, adjustable headband (175). The system includes filter means (400) which is attachable to the headgear structure (100) to cover the structure. A fan mechanism is mounted on the headgear structure to draw air into the headgear structure (100) through the filter means (400). A power supply selectively powers the fan. A facial shield (200) is attachable to the headgear structure (100) to cover the face of the wearer to maintain non-contaminating conditions relative to the wearer. A flexible cuff or hood (300) is attachable to the facial shield (200) to enclose the lower opening of the lens and provides protection for the wearer through which air can be exhausted.
