Patent number: 11819612Abstract: A respiratory mask includes a housing and a cushion or seal that seals on a user's face in use. An upper portion of the seal that is disposed on a user's nasal bridge in use can roll toward and/or over the outer surface of the housing to form a rolling bridge feature that adjusts to different nose sizes. As the rolling bridge rolls, an apex of the seal moves away from the user's face to adjust to larger nose sizes. The apex does not move downward and can move upward relative to a location of the apex in a neutral position of the seal.Type: GrantFiled: October 8, 2020Date of Patent: November 21, 2023Assignee: Fisher & Paykel Healthcare LimitedInventor: Grant Leigh Nelson
