Modular chemical/biological headgear system

摘要

A modular chemical/biological headgear system includes a helmet liner of a resilient shock absorbing material that conforms generally to the shape of a wearer's head, provides a cavity for removable installation of one or more modular filters in the back, and a duct to convey filtered air from the one or more modular filters to a face mask. The helmet liner may be equipped and configured with a variety of interchangeable modular components including hardened outer shells, communications modules, enhanced chemical biological filters, and the like, to meet a wide variety of operational needs.

1. A modular chemical-biological headgear system, comprising:
a helmet liner that is adapted to conform generally to the shape of a wearer's head and which includes a longitudinal cavity adapted for removable installation of a longitudinal duct, and a rear lateral cavity adapted for removable installation of a lateral duet and a modular filter; a facemask module that is releasably attachable to the helmet liner and is adapted to be sealable to the face of the wearer; an exhaust port to enable exhausted air to be vented from the facemask module; a nose cup assembly that is adapted to form a seal over the wearer's nose and mouth and is pneumatically coupled to the exhaust port to prevent exhausted air from circulating inside the facemask module; and wherein when installed said longitudinal duct is disposed in said longitudinal cavity and couples to the lateral duct and facemask module to convey filtered air from the modular filter to the facemask module, and wherein the longitudinal duct and modular filter are removable from the helmet liner.
