Abstract
A cushion assembly for a patient interface includes an elastomeric seal-forming portion that includes a dome-shaped superior region and a saddle-shaped inferior region. The elastomeric sealing portion further includes a first support region extending from the saddle-shaped inferior region to the dome-shaped superior region, the first support region having a consistent elastomeric wall thickness that is greater than the elastomeric wall thickness of the dome-shaped superior region and the saddle-shaped inferior region. In addition, the seal-forming portion include a second support region adjacent the first support region that extends from the saddle-shaped inferior region to the dome-shaped superior region, the second support region being bounded by the first support region on a proximal side and having a distal side opposite the proximal side, the elastomeric wall thickness in the second support region increases from the distal side to the proximal side.
