Patent number: 11529489Abstract: A respiratory mask assembly for delivering breathable gas to a patient includes a frame and a cushion. The cushion has a non-face contacting portion structured to be connected to the frame, a face-contacting portion structured to engage the patient's face, and a central portion that interconnects the non-face contacting portion and the face contacting portion. The frame may be structured to allow a forehead support to assume multiple positions, to compensate for replacement cushions that may have a different profile, shape or size. The cushion is structured to compensate for variations in strap tension, treatment pressure and/or movement of the patient. Headgear may be provided with a strap assembly in which one or more straps is provided with selectively adjustable elasticity or extensibility that may be automatically changed in dependence of treatment pressure and/or treatment type.Type: GrantFiled: July 9, 2021Date of Patent: December 20, 2022Assignee: ResMed Pty LtdInventors: Robert Henry Frater, Joanne Elizabeth Drew, Philip Rodney Kwok, Patrick John McAuliffe, Aaron Samuel Davidson, Robin Garth Hitchcock, Michael Kassipillai Gunaratnam, Donald Darkin, Gary Christopher Robinson
