A patient interface device (2) includes a frame member (4) and a cushion (6) having a main body, a sealing portion, and first and second posts extending from the main body. The frame member defines a first orifice and a second orifice. The first post of the cushion is rotateably received within the first orifice and the second post is rotateably received within the second orifice in a manner that permits the cushion to rotate relative to the frame member.La présente invention concerne un dispositif dinterface patient (2), comprenant un élément de cadre (4) et un coussinet (6) pourvu dun corps principal, dune partie de fermeture hermétique, et de premier et second montants sétendant depuis le corps principal.
