摘要：
An improved patient interface (4) having a cushion (12) and a headgear (16), with the headgear having a pair of engagement elements (24) that each engage the patient with an engagement force, and with the engagement forces being directed generally toward one another. The engagement forces result in frictional forces between the headgear and the patient which resist the cushion from becoming disengaged with the patient. In one embodiment, the engagement elements each include a circumferential brace (44) that engages the head and extends about the ears. In another embodiment, the engagement elements engage the ears of the patient. In a free state, at least a portion of the headgear is of a spiral configuration which makes the patient interface collapsible and relatively easy to pack, such as for traveling.
