Abstract

See full text

A quick release mechanism and headpiece for use with a respirator. The quick release mechanism uses an over center latch pivotly attached to a yoke to control the tension in a pair of upper tension cords. In the latched position the upper tension cords traverse the yoke and together with a pair of lower tension cords support and seal the respirator mask against the face of the wearer. In the unlatched position the upper tension cords loosely support the mask below the chin of the wearer in a parked position. The upper and lower tension cords are attached to a circular shaped headpiece having a crown piece fitting to the top of the head of the wearer and a base portion fitting to the back of the head of the wearer. The headpiece is advantageously comprised of multiple layers wherein the outer layer is comprised of a rigid material and the inner layer is comprised of a compliant material. The rigid layer provides necessary structure to headpiece and the inner layer provides compliance and comfort to the head of the wearer.
