1. A frame assembly for a patient interface for treatment of sleep disordered breathing, the frame assembly configured to connect headgear of the patient interface to a cushion assembly of the patient interface, the frame assembly comprising:
a shroud constructed of a rigid plastic material and including an opening formed therein to receive a flow of air from an air delivery tube, the shroud being structured to, in use, facilitate support of a cushion assembly on a patient's face; and
a pair of upper headgear connector arms extending from respective sides of an upper portion of the shroud and, in use, configured to extend along respective sides of the patient's face, each upper headgear connector arm having a shape that, in use, curves in an upwards direction such that the upper headgear connector arm extends between the patient's eye and ear;
each upper headgear connector arm including:
an upper headgear connection point adapted to receive a respective upper headgear strap;
a shroud connection portion that is connected to the respective side of the upper portion of the shroud; and
a first flexible portion positioned proximal the shroud connection portion and between the shroud connection portion and the upper headgear connection point, the first flexible portion being configured to, in use, allow the upper headgear connector arm to flex outwardly away from the patient's face and inwardly towards the patient's face to adapt to varying facial widths,
wherein the first flexible portion is a living hinge formed by a relatively thinner portion of the upper headgear connector arm disposed immediately between relatively thicker portions of the upper headgear connector arm to form a flexible area,
wherein each upper headgear connector arm further comprises a second flexible portion provided between the first flexible portion and the upper headgear connection point,
wherein the second flexible portion allows the upper headgear connector arm to, in use, flex along its length to conform to the width and profile of patient cheek regions,
wherein a textile material covers a portion of each upper headgear connector arm to provide a patient-contacting surface,
wherein each upper headgear connector arm includes a textile receiving area extending from a first shoulder of the upper headgear connection point to a second shoulder of the first flexible portion to receive the textile material,
wherein the textile receiving area has a reduced thickness as compared to the first shoulder, an upper end of the textile material being adjacent the first shoulder when the textile material is positioned in the textile receiving area, and
wherein the textile receiving area has a reduced thickness as compared to the second shoulder, a lower end of the textile material being adjacent the second shoulder when the textile material is positioned in the textile receiving area.
