1. A frame assembly for a patient interface for delivery of a supply of pressurised air or breathable gas to an entrance of a patient's nasal airways only, the frame assembly comprising:
a ring member; lower arms extending from lower arm connection points radially positioned on the ring member; a joining member extending posteriorly from the ring member at an upper position on the ring member; and upper arms extending from an upper arm connection point at a distal end of the joining member such that the lower arm connection points are in a position anterior from the upper arm connection point, the upper arms adapted to extend over the cheeks of the patient in use; wherein the upper arm connection point and lower arm connection points are spaced apart at a predetermined distance to provide a maximum tilting range for the frame assembly relative to the patient's face, and wherein a center of rotation or pivot point of the frame assembly is provided at a lower side of the frame assembly.
