Abstract

Abstract The present disclosure is directed to a heat reflective shield having a plurality of spherical triangular panels each having aluminum foil on one side and a heat resistant fabric adhered to the other side, for use with a hard hat. The panels are stitched together along their long sides and along their bases with binding tape to define an equatorial stitched bound base border to form a highly reflective side of the shield directed upwardly toward the crown of the hard hat thus forming a reflective heat shield to direct the heat from the sun or other hot heat sources away from the skull of the wearer of the hard hat. A strip of double sided adhesive tape is provided, one side of which is adapted to be adhered to the outside of the top of the heat reflective skull cap and the other side of which is adapted to adhere to the inside of the crown of the hard hat. An adjustable hat band is secured within the hard hat positioned to lie between the hard hat shell and the head of the wearer, and suspension bands are secured to the hat band at their ends with their intermediate portions flex arched to form supports to keep the heat reflective skull cap supported above and out of contact with the head of the wearer.
