The face shield assembly includes a transparent shield panel coupled with a front strap and back strap. The front strap contacts the forehead and spaces the transparent shield panel away from the face. The back strap extends around the head and holds the transparent shield panel on the head. Each of the straps are adjustable for different type head sizes. ## Claims ### Claim 1 A one-piece protective face shield comprising: a transparent shield panel, an integral front and an integral back strap made using a clear flexible sheet material that is optically clear: the transparent shield having a first side edge, a second side edge, and multiple transparent shield panel attachment slots proximate the first side edge and the second side edge; the front strap having a first end and a second end, the first end integrally extending outward from the first side edge, and the second end having a front strap attachment lock tab configured to slide into one of the multiple transparent shield panel attachment slots proximate the second side edge and lock in place; and the back strap having a first end and a second end, the first end integrally extending outward from the second side edge, and the second end having a back strap attachment lock tab configured to slide into one of the multiple transparent shield panel attachment slots proximate the first side edge and lock in place to hold the protective face shield on a person's head. ### Claim 2 (depends on 1) The protective face shield of claim 1, wherein coupling the front strap attachment lock tab to the transparent shield panel attachment slot or slit creates a space between the front strap and the transparent shield panel, wherein the space is configured to position the transparent shield panel a distance D away from a person's face. ### Claim 3 (depends on 2) The protective face shield of claim 2, wherein lengthening or shortening the front strap varies the distance D away from the person's face. ### Claim 4 (depends on 2) The protective face shield of claim 2, wherein coupling the front strap attachment lock tab to different ones of the multiple transparent shield panel attachment slots varies the distance D away from the person's face. ### Claim 5 (depends on 1) The protective face shield of claim 1, wherein prior to sliding into the multiple transparent shield panel attachment slots, the front strap attachment lock tab and the back strap attachment lock tab are prepared by bending or folding inward to allow them to slide into the attachment slots, then once through, bent open or unfolded to prevent pullout, thereby locking the front strap attachment lock tab and the back strap attachment lock tab in the corresponding transparent shield panel attachment slot. ### Claim 6 (depends on 1) The protective face shield of claim 1, wherein the transparent shield panel, the front strap, and the back strap are made of an optically clear flexible sheet material. ### Claim 7 (depends on 1) The protective face shield of claim 1, wherein the transparent shield panel is made of an optically clear material and the front strap and/or the back strap are made from a non-optically clear material. ### Claim 8 (depends on 1) The protective face shield of claim 1, further comprising a pad coupled to the front strap to configured to contact the person's forehead. ### Claim 9 (depends on 8) The protective face shield of claim 8, wherein the pad may be made of a frictional material configured to prevent slippage of the face mask on the person's forehead. ### Claim 10 (depends on 1) The one-piece protective face shield of claim 1, further comprising a pad coupled to the front strap configured to contact the person's forehead. ### Claim 11 (depends on 10) The one-piece protective face shield of claim 10, wherein the pad may be made of a frictional material configured to prevent slippage of the face mask on the person's forehead. ### Claim 12 A protective face shield comprising: a transparent shield panel, an integral front strap and an integral back strap made using a flexible sheet material that is optically clear: the transparent shield panel includes a first side edge, a second side edge, and multiple transparent shield panel hook and loop attachment features proximate the first side edge and the second side edge; the front strap having a first end and a second end, the first end integrally extending outward from the first side edge, and the second end having a front strap hook and loop attachment feature configured to couple with one of the multiple transparent shield panel hook and loop attachment features proximate the second side edge; and the back strap having a first end integrally extending outward from the second side edge and a second end having a hook and loop attachment feature configured to couple with one of the transparent shield panel hook and loop attachment features proximate the first side edge to hold the protective face shield to a person's head, wherein coupling the front strap hook and loop attachment feature to the transparent shield panel hook and loop attachment feature creates a space between the front strap and the transparent shield panel, wherein the space configured to position the transparent shield panel a distance D away from a person's face. ### Claim 13 (depends on 12) The protective face shield of claim 12, wherein lengthening or shortening the front strap varies the distance D away from the person's face. ### Claim 14 (depends on 12) The protective face shield of claim 12, wherein coupling the front strap hook and loop attachment feature to different ones of the multiple transparent shield panel hook and loop attachment feature varies the distance D away from the person's face. ### Claim 15 (depends on 12) The protective face shield of claim 12, wherein the transparent shield panel, the front strap and the rear strap are made of an optically clear flexible sheet material. ### Claim 16 (depends on 12) The protective face shield of claim 12, wherein the transparent shield panel is made of an optically clear material and the front strap and/or the back strap are made from a non-optically clear material. ### Claim 17 (depends on 12) The one-piece protective face shield of claim 12, further comprising a pad coupled to the front strap configured to contact the person's forehead. ### Claim 18 (depends on 17) The one-piece protective face shield of claim 17, wherein the pad may be made of a frictional material configured to prevent slippage of the face mask on the person's forehead. ### Claim 19 A one-piece protective face shield comprising: a transparent shield panel, an integral front and an integral back strap made using a clear flexible sheet material that is optically clear; the front strap having a first end integrally extending outward from a first side edge of the transparent shield panel and a second end configured to adhesively couple with a second side edge of the transparent shield panel; and the back strap having a first end integrally extending outward from the second side edge of the transparent shield panel and a second end configured to adhesively couple with the first side edge of the transparent shield panel to hold the protective face shield to a person's head; wherein adhesively coupling the front strap to the transparent shield panel creates a space between the front strap and the transparent shield panel, wherein the space configured to position the transparent shield panel a distance D away from a person's face. ### Claim 20 (depends on 19) The one-piece protective face shield of claim 19, wherein the distance D may vary by changing a length of the front strap.
