What is claimed is: 1. A method of manufacturing a respiratory mask for delivering a pressurized flow of breathable gas to a patient, the method comprising; molding integrally a mask frame, an inlet portion comprising an inlet for the flow of pressurized breathable gas, a forehead support member, a first hinge connecting the mask frame to the inlet portion, a second hinge connecting the mask frame to the forehead support member, and a cooperative interlocking structure on the mask frame and the inlet portion; folding the mask frame relative to the inlet portion; interlocking the cooperative interlocking structure so that the mask frame is locked in a position relative to the inlet portion; and folding the forehead support member relative to the mask frame so that the inlet portion is interposed between the forehead support member and the mask frame. 2. A method according to claim 1, further comprising attaching a cushion to the mask frame. 3. A method according to claim 2, wherein attaching a cushion to the mask frame comprises integrally molding the cushion with the mask frame. 4. A method according to claim 2, wherein attaching the cushion to the mask frame comprises overmolding or co-molding the cushion with the mask frame. 5. A method according to claim 2, wherein attaching the cushion to the mask frame comprises attaching the cushion to the mask frame by a friction fit, a strap, a clip, or adhesive. 6. A method according to claim 1, further comprising molding a forehead pad integrally with the forehead support member. 7. A method according to claim 1 further comprising molding a folding beam integrally with the forehead support member, wherein, after the forehead support member is folded relative to the mask frame, the angle of the forehead support member relative to the interlocked mask frame and inlet portion may be adjusted by altering an angle of the foldable beam. 8. A method according to claim 7, wherein molding the folding beam comprises: molding a third integral hinge between the forehead support member and a first end of the foldable beam; molding at least one fourth integral hinge between the first end of the foldable beam and a second end of the foldable beam; and molding a fifth integral hinge between the at least one fourth integral hinge and the second end of the foldable beam. 9. A method according to claim 8, wherein the foldable beam comprises a channel between the third living hinge and the at least one fourth living hinge and the second end of the foldable beam comprises a tab configure to be inserted in the channel. 10. A method according to claim 9, wherein the tab is configured to be retained in a plurality of discrete positions in the channel. 11. A respiratory mask for delivering a flow of pressurized breathable gas to a patient, comprising: a mask frame; an inlet portion comprising an inlet for the flow of pressurized breathable gas, the inlet portion being connected to the mask frame by a first living hinge; and a forehead support member connected to the mask frame by a second living hinge, wherein the mask frame and the inlet portion comprise interlocking structure to lock the mask frame and the inlet portion together when the mask frame is folded relative to the inlet portion and the inlet portion is interposed between the forehead support member and the mask frame when the mask frame is folded relative to the forehead support member. 12. A respiratory mask according to claim 11, further comprising a cushion supported by the mask frame. 13. A respiratory mask according to claim 12, wherein the cushion is integrally molded with the mask frame, overmolded to the mask frame, co-molded with the mask frame, or attached to the mask frame by a friction fit, a strap, a clip, or adhesive. 14. A respiratory mask according to claim 11, further comprising a folding beam, wherein the folding beam is connected at a first end to the forehead support member by a third living hinge and, after the forehead support member is folded relative to the mask frame, the angle of the forehead support member relative to the interlocked mask frame and inlet portion may be adjusted by altering an angle of the foldable beam. 15. A respiratory mask according to claim 14, wherein the folding beam comprises at least one fourth integral hinge between the first end of the foldable beam and a second end of the foldable beam and a fifth integral hinge between the at least one fourth integral hinge and the second end of the foldable beam. 16. A respiratory mask according to claim 15, wherein the foldable beam comprises a channel between the third living hinge and the at least one fourth living hinge and the second end of the foldable beam comprises a tab configure to be inserted in the channel. 17. A respiratory mask according to claim 16, wherein the tab is configured to be retained in a plurality of discrete positions in the channel. 18. A respiratory mask according to claim 17, wherein the tab comprises a plurality of detent lugs and the channel comprises a plurality of detent slots. 19. A respiratory mask according to claim 11, wherein the forehead support portion comprises an offset portion configured to at least partially over the mask frame when the mask frame is folded relative to the forehead support member. 20. A respiratory mask according to claim 11, further comprising strap attachment portions provided to the forehead support member. 21. A respiratory mask, comprising: a mask frame comprising a mask cushion; an air inlet portion having an inlet tube, the air inlet portion being connected to the mask frame by at least one first living hinge; and a forehead support comprising forehead padding, the forehead support being connected to the mask frame by at least one second living hinge.
