A headgear for a respiratory mask of a ventilator or CPAP device is provided. The headgear includes a strap portion formed of a substantially inextensible material. The strap portion has formed on one end thereof a connecting structure configured to connect to a mask of the ventilator or CPAP device. One advantage is that the mask will not or at least will be less inclined to lift off the face as mask pressure is increased.

1. A mask for use with a ventilator or a CPAP device, comprising: a frame configured to be connected to headgear;a cushion mounted to the frame, the cushion being configured to seal around an airway of a patient, the cushion and the frame being selectively adjustable relative to one another in a plurality of discrete portions to thereby tailor the cushion to actively conform with the patient's facial contour, the frame being movable between a plurality of positions relative to the cushion at each discrete portion; anda plurality of connecting structures fixed to the frame and the cushion, each connecting structure being configured to set the frame at any of said plurality of positions independently of tension in the headgear. 2. A mask as in claim 1, wherein each connecting structure a) is connected to a corresponding discrete portion of said plurality of discrete portions, b) includes an end fixed to the cushion and c) is movable relative to the frame to thereby adjust the relative position between the frame and the cushion, and therefore the cushion and the patient's face. 3. A mask as in claim 2, wherein the frame includes two wall structures which are spaced apart with a gap between the two wall structures, and an adjustment device positioned within the gap and accessible along a periphery of the frame, the plurality of connecting structures being threadedly coupled to the adjustment device to allow movement of the respective connecting structure ends that are fixed to the cushion and allow movement of the cushion at the corresponding discrete portion of the cushion, towards and away from the frame. 4. A mask as in claim 1, wherein the cushion comprises a foam covered by a silicone skin. 5. A mask as in claim 1, wherein the frame is substantially or partially encapsulated within a material of the mask. 6. A mask according to claim 1, wherein each connecting structure connects a corresponding first connection point on the cushion to a corresponding second connection point on the frame, the corresponding first and second connection points being located at a predetermined one of the plurality of discrete portions of the mask, each connecting structure being configured so that selective adjustment of the cushion and frame relative to each other in the predetermined one of the plurality of discrete portions of the mask adjusts a distance between the corresponding first and second connection points. 7. A mask according to claim 6, wherein each discrete portion is associated with a respective connecting structure. 8. A mask as in claim 1, wherein the cushion comprises an end that is distal to the frame and a distance between the frame and the distal end of the cushion is selectively adjustable in the plurality of discrete portions, to thereby tailor the cushion to actively conform with the patient's facial contour. 9. A mask assembly for use with a ventilator or a CPAP device, comprising: a cushion configured to sealingly engage a patient's face; anda frame comprising a plurality of discrete engagement zones, the frame being adapted to adjustably engage the cushion at each engagement zone, the frame comprising a plurality of headgear connectors configured to connect headgear to the frame,wherein at each engagement zone, the frame is movable between a plurality of positions relative to the cushion and an adjustment member directly connected to the frame and the cushion is configured to set the frame at each of the plurality of positions independently of tension in the headgear. 10. A mask assembly according to claim 9, wherein a portion of the frame in each engagement zone is movable relative to the cushion independently of movement in other engagement zones. 11. A mask assembly according to claim 10, wherein each adjustment member comprises a corresponding threaded body and a threaded thumb wheel. 12. A mask assembly according to claim 11, wherein the frame is configured so that movement of each threaded thumb wheel along the corresponding threaded body corresponds to movement of the frame relative to the cushion. 13. A mask assembly according to claim 9, wherein each adjustment member engages the cushion at a location on a periphery of the cushion. 14. A mask assembly according to claim 9, wherein the cushion comprises an annular flange, and each adjustment member engages the flange. 15. A mask assembly according to claim 9 further comprising the headgear, wherein the frame is attachable to the headgear to position the mask assembly on the patient's head. 16. A mask assembly according to claim 9, wherein each adjustment member is configured to advance and retreat through the frame, and wherein the frame is configured to move between a plurality of positions relative to the cushion when at least one of the adjustment members advances and retreats through the frame. 17. A mask assembly for use with a ventilator or a CPAP device, comprising: a cushion configured to sealingly engage a patient's face;a frame adapted to adjustably engage the cushion at a plurality of discrete locations on the cushion, a portion of the frame being movable between a plurality of positions relative to the cushion at each discrete location independent of other portions of the frame at other discrete locations, the frame comprising a plurality of headgear connectors configured to connect headgear to the frame; anda plurality of adjustable support members, each adjustable support member being connected to the frame and the cushion at a respective one of the plurality of discrete locations and being configured to set the frame at any one of said plurality of positions without adjustment of tension in the headgear. 18. A mask assembly according to claim 17, wherein each of said plurality of adjustable support members comprises a threaded body and a threaded thumb wheel. 19. A mask assembly according to claim 18, wherein the portion of the frame at the corresponding discrete location is configured so that movement of the threaded thumb wheel along the threaded body corresponds to movement of the frame relative to the cushion. 20. A mask assembly according to claim 17, wherein each adjustable support member engages the cushion at a location on a periphery of the cushion. 21. A mask assembly according to claim 17, wherein the cushion comprises an annular flange, and each adjustable support member engages the flange. 22. A mask assembly according to claim 17 further comprising the headgear, wherein the frame is attachable to the headgear to position the mask assembly on the patient's head. 23. A mask assembly according to claim 17, wherein each of the plurality of adjustable support members is configured to advance and retreat relative to the frame. 24. A mask assembly for use with a ventilator or a CPAP device, comprising: a cushion configured to sealingly engage a patient's face;a frame comprising:a plurality of headgear connectors configured to connect the frame to headgear; anda plurality of discrete engagement zones, the frame being adapted to adjustably engage the cushion at each engagement zone; anda plurality of adjustment members affixed to both the cushion and the frame,wherein the cushion comprises a distal end that is distal to the frame and comprises a proximal end that is proximal to the frame,wherein the frame comprises a distal end that is distal to the cushion and comprises a proximal end that is proximal to the cushion, andwherein at each engagement zone, the proximal end of the frame is movable between a plurality of positions relative to the distal end of the cushion and one of the plurality of adjustment members is configured to set the proximal end of the frame at each of the plurality of positions independently of tension in the headgear. 25.
