Abstract
A respiratory mask has an adjustable forehead support member that is simple and inexpensive to manufacture. The forehead support member may be adjusted by rotating a forehead pad about an off-center bore or by bending an angular adjustment beam. The mask has a mask cushion with an accordionate membrane having at least two hinged portions. The mask may be constructed with a mask frame, the mask cushion, and the forehead support member molded as one piece.
