Abstract: A patient interface device (8) that includes a cushion (12) structured to receive a flow of treatment gas, a frame (14) having a central portion (17) structured to couple with the cushion and a strap (18a, 18b) extending from the central portion, a headgear component (28) including at least one of a top portion (30) adapted to fit on top of a patient's head and a rear portion (32) adapted to fit behind the patient's head, and a coupling mechanism (34a, 34b) structured to couple the strap to the headgear component, wherein an end portion of the strap is structured to pass through an opening in the coupling mechanism, fold back in a direction toward the central portion of the frame, and releasably attach to the strap, such that pulling the end portion of the strap toward the central portion of the frame tightens the patient interface device.

Abstract: A patient interface device for delivering a flow of breathing gas to an airway of a patient, comprises a mask component and auto-adjusting headgear. The auto-adjusting headgear comprises one or more straps wherein the materials have elasticity characteristics such that the headgear self-adjusts. The headgear comprises two lateral strap sections, a rear strap section, and a top strap section. The strap sections are of varying materials and thicknesses to control the properties of the strap sections. In one embodiment, at least a portion of a strap includes a high friction material disposed so as to contact a portion of the user responsive to the headgear being donned by a user.
