Abstract
Abstract A protective helmet assembly to be worn on the head of a person includes arotective shell and a removable, adjustable suspension system mounted on the inner surface of the shell. The suspension system includes an impact liner mounted on the inner surface of the protective shell, a plurality of sizing pads removably mounted on the impact liner, and a plurality of spare sizing pads. The plurality of sizing pads and spare sizing pads are sized and shaped of varying thickness so as to enable the protective helmet assembly to accommodate a broad range of head sizes and shapes. The protective helmet assembly further includes a pair of earcups pivotally mounted on opposite sides of the shell. Each of the earcups are pivotally adjustable by a pair of ratchet buckles mounted on the protective shell, and a pair of retainer straps. Each retainer strap is attached to the outer surface of one of the earcups and to one of the ratchet buckles. When each retainer strap is tightened by stepwise adjusting the retainer strap through one of the ratchet buckles, the retainer strap pulls the earcup pivotally inward creating a tight pressure seal around the ear of the head of the person. The protective helmet assembly additionally includes a vertical strut mounted on both the front/left side and front/right side of the protective shell, each vertical strut including a hooked-shaped slot, and a facemask having a left end and a right end. The facemask includes a pair of pins, one mounted on the left end and one mounted on the right end, each pin being pivotally mountable in one of the hooked-shaped slots.
