- 32 - Abstract Protective Face Mask System Using Varying Thicknesses of Energy Absorption & Dissi- pation Material A protective facial mask system having an outer, high impact, rigid, polycarbonate layer and an inner, flexible, relatively soft layer of energy absorption and dissipating material (e.g. an viscoelastic polymer). The inner layer has dif- ferent thicknesses (-1/8"-1/4"), affording greater (thicker) protection where underlying bone structure is weaker (e.g., nasal region), and thinner where the bone structure is stronger (e.g. over flanking, supra-orbital/glabella regions). The mask covers the zygomatic, temporal, nasal and frontal bones, resting on the buttresses of the cranial facial area, and also can cover the maxilla and the man- dible sides. At its upper perimeter, the mask extends above the supra-orbital ridges, leaving the remainder of the frontal bone, eyes, nostrils, and mouth of the user open. The inner layer closely contacts and conforms to the contours of the person's face, preferably in face-to-face surface engagement.
