    摘要: A quick release mechanism and headpiece for use with a respirator. The quick release mechanism uses a cam latch pivotally attached to a yoke to control the tension in an upper tension strap. In the latched position the upper tension strap traverses the yoke to support and seal the respirator mask against the face of the wearer. In the unlatched position the upper tension straps loosely support the mask below the chin of the wearer in a parked position. In one embodiment, a guide is provided on the yoke to ensure that the mask may be consistently donned and doffed with minimal effort (e.g., potential one-handed donning and doffing). An opening may also be provided in the face mask and optionally in the yoke, and a filter may be disposed within the opening to provide the desired filtration of inhaled gases.
