US Patent 9241529 Air-cooled hard hat

An air-cooled hard hat includes a hard hat and a fan arrangement. The fan arrangement has a fan, an input, and at least one outlet for distribution of air. An opening is made on the hard hat, which the at least one outlet feeds through. The opening may be located on the front face of a laterally facing wall of the hard hat. When the fan arrangement is attached to the hard hat, the outlet provides air to the interior of the hard hat through the hole. Additionally, another opening may be located along a front brim of the hard hat. A second outlet that feeds through the opening in the brim provides air down onto the face of the user.
