PERSONAL PROTECTION SYSTEM WITH HEAD UNIT HAVING EASY ACCESS CONTROLS AND PROTECTIVE COVERING HAVING GLARE AVOIDING FACE SHIELD
First Claim
1. A protective covering for draping over a head unit to provide a sterile barrier between a user and an external environment, said protective covering comprising:
- 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 being configured to provide 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 being smaller than said second radius of curvature to reduce glare directed toward the eyes of the user.

Abstract
A personal protection system is provided for creating a sterile barrier between a user and an external environment. The personal protection system includes a head unit having a ventilation unit with a fan for distributing air to the user. The personal protection system also provides a protective covering draped over the head unit. The protective covering includes a flaccid shroud and a transparent face shield mounted to the flaccid shroud. The face shield is mounted to the head unit using a plurality of mounting elements. The face shield is mounted such that a top portion of the face shield has a larger radius of curvature when mounted that a bottom portion of the face shield. This reduces the glare directed toward the user. A control panel for the ventilation unit is also provided on a chin bar of the head unit for easy access by the user.
