A bumper assembly for a patient interface comprising a resilient seal forming portion comprising: a dome-shaped upper region (3180A); a saddle-shaped lower region (3180G); a first support region (3180E) having a constant The wall thickness, preferably 2mm, is greater than the wall thickness of the dome-shaped upper region and the saddle-shaped lower region, preferably 0.3mm; the second support region (3180D), which has a variable wall thickness and is proximally formed by the first A support region (3180E) defines and has a distal side opposite the proximal side. In claim 1, the wall thickness in the second support region (3180D) increases from distal to proximal, preferably 2 mm to 1.3 mm. Preferably, the wall thickness of the third support region (3180F) is 1.3mm, the compliant region (3180C) is 0.85mm, and the sheet portion (3180H) is 0.5mm. Preferably, the flap (3180H) moves independently of the tether 3110. |
