Claim:
1. A patient interface device, comprising: a patient sealing assembly adapted to communicate a flow of breathing gas within an airway of a patient, the patient sealing assembly including a cushion and a frame member having a faceplate portion and an extension portion extending from the faceplate portion, the cushion being coupled to the faceplate portion; a forehead member structured to engage a forehead of the patient; a flexible elongated member having a first end portion and a second end portion, the first end portion being coupled to the forehead member and the second end portion being coupled to the extension portion of the frame member; a drive assembly coupled to the second end portion of the flexible elongated member, the drive assembly being structured to selectively cause the second end portion of the flexible elongated member to move relative to the extension portion of the frame member in a first direction, wherein movement of the flexible elongated member relative to the extension portion in the first direction causes movement of the frame member relative to the forehead member in a second direction transverse to the first direction; and a shaping form, wherein the flexible elongated member is moveably received through the shaping form, wherein the shaping form is structured to change a shape of the flexible elongated member when the flexible elongated member is moved through the shaping form, and wherein movement of the flexible elongated member relative to the frame member in the first direction causes a selected portion of the flexible elongated member to move through the shaping form, wherein the shaping form includes a front surface and a rear surface, the rear surface being positioned closer to the forehead member than the front surface, wherein the flexible elongated member is a tubular member, wherein the shaping form is structured to change the shape of the selected portion from a generally flat shape to a generally rounded shape when the flexible elongated member is moved through the shaping form from the front surface to the rear surface.
