Abstract
A mask assembly adapted for use with a positive airway pressure device includes a mask frame, a cushion provided to the frame, a forehead support assembly, and a neck to connect the frame to the forehead support assembly. The neck includes at least one wall including a first edge and a second edge, wherein lower ends of the first edge and the second edge converge towards one another in an upward direction and upper ends of the first edge and second edge diverge from one another in an upward direction. The mask assembly is configured so that a relatively narrow portion of the neck overlies the bridge of the nose or is between the eyes of a user. The relatively narrow portion is a portion of the neck where a distance between the first edge and second edge is smallest.
