Abstract

A patient interface device (10) includes a patient sealing assembly (60) including a cushion (70), and a frame member (80) coupled to the cushion, and an adjustable forehead support assembly (200) provided at the distal end (120) of the frame member. The adjustable forehead support assembly includes an adjustment mechanism (202) coupled to a forehead cushion (204), wherein the adjustment mechanism includes a forehead cushion support member (212) having a base portion (216) coupled to the forehead cushion and an vertical/upright rotatable wheel member (214). Rotation of the wheel member causes movement of the frame member and the cushion relative to the forehead cushion.
