Abstract
Abstract A protective helmet of hard thermoplastic synthetic resin is provided with a flexible harness having a sweatband strap extending around the inside of the crown at the lower edge of the crown with a plurality of integral projecting portions extending upwardly and inwardly from the strap toward the center of the crown. At the terminal end of each of the projecting portions there is provided an integral outwardly protruding generally cylindrical hollow cup which opens inwardly and which has a through opening in the bottom of the cup of a smaller diameter than the inside diameter of the cup. A plurality of inwardly extending studs integral with the crown pass, one through each of the openings of the cups. Friction may be relied upon to hold the cups in place or heat may be applied to the end of the stud inside of the receiving cup to expand the end of the stud and hold the harness more firmly to the helmet.
