The headgear (50) includes side straps (53) and rigidizers (55) provided to respective side straps (53). Each rigidizer (55) includes a first end portion (55(1)) that provides a connector (56) structured to engage a respective end of the nasal prong assembly and an inwardly curved protrusion in the form of a cheek support (62) that curves inwardly of the connector (56). The cheek support (62) is adapted to follow the contour of the patient's cheek and guide a respective end portion (63) of the side strap (53) into engagement with the patient's cheek to provide a stable cheek support.1/250 50 60 60(1) 53(1) 60(2) 53(1) -54 65 57 66 52 57(1) 5357(1 53 58 55(1) 55 62 52 63 55(3) 56 56 62 58 FIG. 1-1
