摘要：
A cushion assembly for a patient interface includes an elastomeric seal-forming portion that includes a dome-shaped superior region (3180A)； a saddle-shaped inferior region (3180G)； a first support region (3180E) having a consistent wall thickness, preferably 2 mm, that is greater than the wall thickness of the dome-shaped superior and the saddle-shaped inferior regions, preferably 0.3 mm； a second support region (3180D) having a varied wall thickness and is bounded by the first support region (3180E) on a proximal side and having a distal side opposite the proximal side. In claim 1, the wall thickness in the second support region (3180D) increases from the distal side to the proximal side, preferably 2 to 1.3 mm. Preferably, wall thickness of a third support region (3180F) is 1.3 mm, a compliant region (3180C) is 0.85 mm and a flap (3180H) is 0.5 mm. Preferably flap (3180H) moves independently of a loop connection (3110).
