Abstract
Abstract An improved ear guard assembly, particularly for amateur wrestlers. The ear guard includes a reinforcing plate member having head strap engaging slots with inner and outer sheet foam energy absorbing layers. The assembly is enclosed by a molded plastic skin cover having strap engaging apertures in registry with the strap engaging slots of the reinforcing plate which are reinforced to prevent tearing of the ear guards. The cover further has an inside peripheral surface which has ribs engaging the outer edge of the reinforcing plate to reduce the tendency for tearing of the cover by the plate edge. The outer cover preferably has a glossy outer surface, present a low coefficient of friction and a matte inner surface thereby aiding in retaining the ear guards in position on the wearer's head.
