Abstract
Abstract Existing devices for stabilizing a safety helmet such as a hard hat are either unduly complicated or ill adapted as retrofits for existing helmets. A simple restraining device for use on new or existing helmets includes a bracket located at the center of the interior of each side of the helmet for pivotally supporting front and rear headbands. Pins extending through the headbands into arcuate slots in the brackets limit rotation of the front and rear headbands with respect to the brackets. A force tending to lift or rotate the helmet from the wearer's head will cause the headbands to pivot downwardly and inwardly against the wearer's head, thus inhibiting removal thereof from the head of the wearer.
