Ergonomic headwear systems and apparatuses for reducing light exposure

Abstract

Headwear reduces radiation exposure with a brim on a top crown that generally surrounds the head. The brim is above a bottom of the crown to avoid interfering with the ears, face, and/or adjustment strap of the cap, which may be of critical importance for those needing protection from sunlight. Brims are positionable a half-inch or more above the bottom of the crown and may completely or partially extend about the crown. Brims may extend at an angle of 20-degrees or more to provide clearance for the ears, face, and any adjustment structure. Brims may be integral with or nondestructively removable from the crown and may include bands or cut-outs for existing brims, bills, or adjustment structures for fitting of hats to which removable brims are added. Headwear may be rigid or a flexible canvas.

What is claimed is: 
     
         1 . An apparatus for providing comfortable radiation shading, the apparatus comprising:
 a brim having an inner perimeter shaped to seat on a crown of a hat worn on a human head; and   a band configured to lay on a bill of the hat, wherein the band connects at both ends to the brim.   
     
     
         2 . The apparatus of  claim 1 , wherein the brim is opaque, flexible, and over two inches in width. 
     
     
         3 . The apparatus of  claim 2 , wherein the brim and the band are non-destructively removable from the crown, wherein the band has a lesser width than the brim, and wherein the band and the brim completely surround the hat. 
     
     
         4 . The apparatus of  claim 3 , wherein the brim and the band are sized and shaped to seat the brim on the hat over one inch above a vertical bottom of the hat so as to avoid ears of a wearer of the hat and an adjuster of the hat.
