Abstract
Abstract The ends of a strap are connected by fastening members to opposite sides of the bottom of a safety hat at locations that are in front of the ears when the hat is worn. The strap slants from the hat down across the ears and around the nape of the neck. A pair of ear covers between the strap and the head engage the head around the ears and are connected to the strap by retaining members connected to the outer sides of the ear covers, across which the strap extends obliquely to hold them against the head.
