Abstract

A patient interface assembly is configured to deliver pressurized gas to the patient's airways. The patient interface assembly includes a patient interface structure that is configured to sealingly engage the patient's face. The patient interface includes a receptacle. The patient interface assembly further includes headgear configured to support the patient interface structure on the patient's head. The headgear includes a clip that is receivable by the receptacle. The receptacle and the clip together form a multiple stage connection arrangement in which each of the multiple stages corresponds to an interlocked position of the clip in the receptacle. Each stage is associated with a corresponding range of headgear tension.
