Abstract
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.
