A patient interface device (100, 200, 300, 400) for a pressure support system, the pressure support system comprising a fluid coupling conduit and a gas flow generator coupled to the fluid coupling conduit, the gas flow generator being structured to produce a flow of breathing gas for a patient, the patient interface device comprising: (a) a frame member (120, 220, 320, 420) structured to be secured to the patient; the frame member having a first arm portion and a second arm portion; wherein the first arm portion extends from proximate the body member in a first direction; wherein the second arm portion extends from proximate the body member in a second direction generally opposite the first direction and (b) an adjustment assembly (110, 210, 310, 410) comprising: a body member (130, 230, 330, 430) coupled to the frame member, the body member being structured to be fluidly coupled to the fluid coupling conduit, and a dial member coupled to each of the frame member and the body member, wherein the dial member has a first recessed portion and a second recessed portion opposite the first recessed portion, and the frame member partially wraps around dial member so that dial member is generally internal with respect to frame member, and the frame member is under tension in operation, wherein the adjustment assembly is structured to move between a first position and a second position, wherein the frame member exerts a force on the dial member, and wherein, when the adjustment assembly moves from the first position to the second position, the force increases, and wherein when adjustment assembly (110, 210, 310, 410) is in the first position, first and second arm portions (122,124) engage respective recessed portions (180,182) and when adjustment assembly is in the second position, first and second arm portions (122,124) do not engage recessed portions (180,182). (a) a frame member (120, 220, 320, 420) structured to be secured to the patient; the frame member having a first arm portion and a second arm portion; wherein the first arm portion extends from proximate the body member in a first direction; wherein the second arm portion extends from proximate the body member in a second direction generally opposite the first direction and (b) an adjustment assembly (110, 210, 310, 410) comprising: a body member (130, 230, 330, 430) coupled to the frame member, the body member being structured to be fluidly coupled to the fluid coupling conduit, and a dial member coupled to each of the frame member and the body member, wherein the dial member has a first recessed portion and a second recessed portion opposite the first recessed portion, and the frame member partially wraps around dial member so that dial member is generally internal with respect to frame member, and the frame member is under tension in operation, a body member (130, 230, 330, 430) coupled to the frame member, the body member being structured to be fluidly coupled to the fluid coupling conduit, and a dial member coupled to each of the frame member and the body member, wherein the dial member has a first recessed portion and a second recessed portion opposite the first recessed portion, and the frame member partially wraps around dial member so that dial member is generally internal with respect to frame member, and the frame member is under tension in operation,
