Patent attributes
A visor mounting apparatus for mounting a face shield to a helmet includes end portions mounted to the helmet and connecting ends of the shield to the helmet and a front attachment between the helmet and the shield comprising a mounting portion for attaching to the shield and an engagement portion having a tapered slot configured for clasping a brim of the helmet. In another embodiment the front attachment is a gasket that extends for the entire width of the shield and seals against liquid entering between the shield and the helmet. The face shield can have a varying thickness profile to correct for optical aberrations, the thickness profile taken from a center toward one lateral end that has a first region that sinusoidally decreases, and then an adjacent second region that sinusoidally increases to a third region adjacent the second region that sinusoidally decreases.
