Personal protection system with head unit having easy access controls and protective covering having glare avoiding face shield

A personal protection system for providing a sterile barrier between a user and an external environment, said system comprising:

• a head unit adapted to be worn on the head of the user, said head unit including:
• a support structure;
• a ventilation unit supported by said support structure, said ventilation unit having a fan that discharges air toward the user;
• and
• a chin bar depending from said support structure;
• a protective covering draped over said head unit, said protective covering including:
• a flaccid shroud including a filter section for filtering air entering the shroud from the external environment;
• a face shield formed of a flexible and transparent material and including a top portion, a bottom portion, and a sealing perimeter, said shroud sealed to said face shield along said sealing perimeter;
• a pair of lower mounting elements disposed on said face shield along said bottom portion of said face shield;
• and
• an upper mounting element disposed on said face shield along said top portion of said face shield, said upper and lower mounting elements defining three mounting locations at which said face shield is mounted to the head unit;
• said face shield when mounted to said head unit provides a first radius of curvature along said bottom portion and a second radius of curvature along said top portion wherein said first radius of curvature and said second radius of curvature are disposed in parallel planes and wherein said first radius of curvature is smaller than said second radius of curvature to reduce glare directed toward the eyes of the user.

• a head unit adapted to be worn on the head of the user, said head unit including:
• a support structure;
• a ventilation unit supported by said support structure, said ventilation unit having a fan that discharges air toward the user;
• a chin bar depending downwardly from said support structure to define a facial opening for the user;
• and
• a control panel disposed on said chin bar, said control panel including at least one control switch for said ventilation unit;
• a protective covering draped over said head unit, said protective covering including:
• a flaccid shroud including a filter section for filtering air entering the shroud from the external environment;
• a face shield formed of a flexible and transparent material and including a top portion, a bottom portion, and a sealing perimeter, said shroud sealed to said face shield along said sealing perimeter;
• a pair of lower mounting elements disposed on said face shield along said bottom portion of said face shield;
• and
• an upper mounting element disposed on said face shield along said top portion of said face shield, said upper and lower mounting elements defining three mounting locations at which said face shield is mounted to the head unit;
• said three mounting locations providing said face shield with a first radius of curvature along said bottom portion when said face shield is mounted to the head unit using said lower mounting elements and a second radius of curvature along said top portion when said face shield is mounted to the head unit using said upper mounting element, said first radius of curvature and said second radius of curvature being disposed in parallel planes, said first radius of curvature being smaller than said second radius of curvature to reduce glare directed toward the eyes of the user.
