| Abstract: |
A face shield assembly for the protection of the eyes and face of a wearer from infectious, hazardous or undesirable substances. The shield assembly includes a semi-flexible forehead support strip joined at its ends to the ends of a semi-flexible protective face panel support strip. The forehead support strip includes a central strip portion, intermediate strip portions foldable to (and extending outwardly from) the central portion, and end strip portions foldable to (and extending outwardly from) the intermediate strip portions. A semi-flexible, transparent protective face panel is affixed at its upper edge portion to the face panel support strip. An elastic head band is affixed at its ends to an end of the forehead support strip and extends through slip fasteners affixed to the central strip portion of the forehead support strip proximate the fold line between the central portion and the intermediate strip portions. When the elastic head band is pulled through the slip fasteners the intermediate strip portions are folded to the end portions of the forehead support strip and the ends of the face panel support strip are held in abutment to the ends of the central strip portion of the support strip. Thereafter, when the head band is placed about the head of the wearer of the eye/face shield assembly the forehead support strip in its central portion forms into an arcuate shape surrounding the forehead of the wearer and supports the protective face panel support strip, with the face panel, in arcuate spaced face protection orientation on the wearer's head.
