  • Patent number: 11006689
    Abstract: A face protection system is provided in the form of a face shield attachable to a hard hat. An upper portion of the face shield includes at least one loop surrounding at least a portion of an opening. The opening is sized to allow at least a portion of a dome of the hard hat to fit upward therethrough, but small enough to keep the entire hard hat from passing therethrough, so that the upper portion of the face shield rests upon the hard hat. A mask extends down from the upper portion of the face shield and preferably includes a plurality of columns on a front side thereof in front of a face of a wearer of the hard hat. Preferably ribs extend laterally between the columns, with the columns and ribs together forming the mask. A visor can optionally be placed inboard of the mask.
