A patient interface assembly that includes a patient interface device, a headgear, and coupling member joining the interface device to a headgear. In one embodiment, a spring biases the interface device against the face during use. In a further embodiment, the patient interface device is a nasal cushion having a formable support mounted to the nasal cushion for providing support and adjustment of the nasal cushion to improve fit and comfort. The headgear assembly in one embodiment is a semi-rigid, minimal contact harness and includes an adjustment assembly that allows for a simultaneous adjustment of multiple straps. An adjustment assembly on the headgear provides a gross adjustment of the position of the interface relative to the patient and a biasing force to urge the patient interface device against the patient's face. In a further embodiment, a pair of rigid connecting members couple the patient interface device to the headgear.

What is claimed is: 1. A patient interface assembly for use in the delivery of a breathing gas to a patient, comprising: (a) a patient interface device; (b) a headgear adapted to be worn by a patient; and (c) a coupling member adapted to couple the patient interface device to the headgear, wherein the patient interface device is pivotally connected to the headgear via the coupling member, and wherein the coupling member includes an angle adjustment assembly for adjusting an angle of the patient interface device relative to such a patient, the angle adjustment assembly comprising: (1) a mounting bracket adapted to be mounted to the headgear, (2) an angular pivot housing, and (3) a pivot tube mounted within the angular pivot housing, wherein the mounting bracket, angular pivot housing, and the pivot tube are pivotable about a common axis. 2. The patient interface assembly of claim 1, wherein the mounting bracket has mounting bracket arms each having locking elements corresponding to preset angular positions, and the angular pivot housing comprises extension arms having a locking element for mating with the locking elements on the mounting bracket arms. 3. The patient interface assembly of claim 1, wherein the patient interface device comprises a nasal cushion and a nares element. 4. The patient interface assembly of claim 1, further comprising a cradle coupling the patient interface device to the coupling member. 5. The patient interface assembly of claim 4, further comprising an exhaust diffusion plate mounted on the cradle. 6. The patient interface assembly of claim 1, wherein the headgear comprises: a cross strap adapted to extend over the top of a patient's head; a forehead strap adapted to extend over the forehead and temples of such a patient; and a rear strap adapted to extend about the rear portion of such a patient's head. 7. The patient interface assembly of claim 2, wherein the cross strap, the forehead strap, and the rear strap are connected to each other by an adjustment assembly. 8. The patient interface assembly of claim 7, wherein the adjustment assembly provides simultaneous adjustment of both the cross strap and the rear strap. 9. The patient interface assembly of claim 1, wherein the coupling member includes a length adjustment assembly for adjusting a distance between the coupling member and the patient interface device. 10. The patient interface assembly of claim 1, further comprising a spring associated with the coupling member and adapted to bias the patient interface device against such a patient's face responsive to the patient interface assembly being donned by such a patient.
