Abstract
A protective helmet having a rigid shell with a headband and crown suspension system and provided with readily adjustable sound-attenuating earcup assemblies, in which right and left hand flexible fabric earcup assembly supports are secured at locations adjacent to the upper ends thereof to the rigid shell for movement of the earcup assemblies carried thereby toward and away from the wearer's head, and in which an adjustable chin strap assembly, the ends of which are anchored to the rigid shell at locations below the points of attachment of the earcup supports to the shell, carries respective fastener elements adapted releasably to be engaged with fastener elements adjacent to the lower ends of the cup supports so that, when the chin strap is pulled to draw the helmet down firmly to engage the suspension with the wearer's head, the earcup assemblies are moved toward the wearer's head to cause the seals thereof firmly to engage the portions of the wearer's head around his ears. One or more pads of energy absorbing material are readily detachably and reattachably secured to the outer surface of the earcup supports and to the portion of the headband at the back of the wearer's head.
