The frame has a viewing opening for a user to see out of the frame. A shield is mounted to the frame, and can be moved between a open and closed positions. A pivot arm connects the shield to the frame and is mounted to the inside of both the frame and shield to avoid exposure. An outer mount and inner mount can also be provided to automatically adjust the width of the head top. A hinge connects them allowing the inner mount to laterally pivot with respect to the outer mount to accommodate users with different head sizes. A forehead member also adjusts to a user's forehead. ## Claims ### Claim 1 An adjustable head harness mount comprising: an outer mount having a first connector for connecting the outer mount to a head top;

said body having opposed free ends; said main body being adapted to connect to headgear; a head strap connected to said free ends; said head strap drawing said free ends to a second radius of curvature which is less than said first radius of curvature; whereby said adjustable forehead frame snugly fits against a user's head. ### Claim 14 (depends on 13) The adjustable forehead frame of claim 13, further including first and second wings, said first wing extending from one of said opposed free ends and said second wing extending from the other of said opposed free ends; said first and second wings being movable with respect to said main body from a first position to a second position; said first and second wings each having an adjustable second radius of curvature which is less than said first radius of curvature when said first and second wings are in said second position; whereby said adjustable forehead frame snugly fits against a user's head. ### Claim 15 (depends on 14) The adjustable forehead frame of claim 14, further including a first hinge connecting said first wing to one of said opposed free ends and a second hinge connecting said second wing to the other of said opposed free ends. ### Claim 16 (depends on 15) The adjustable forehead frame of claim 15, wherein said hinge is a living hinge. ### Claim 17 (depends on 15) The adjustable forehead frame of claim 15, wherein said hinge is a mechanical hinge. ### Claim 18 (depends on 13) The adjustable forehead frame of claim 13, further including pads attached to said forehead member, said pad having channels to direct air over the user. ### Claim 19 A headgear comprising: a frame for mounting on a user's head; said frame having a viewing opening for a user to see out of said frame; said viewing opening having a perimeter; a shield mounted to said frame, said shield being movable between a first position wherein said shield covers said user opening and a second position wherein said viewing opening is exposed;
