Adjustable locking forehead support for a patient interface device

Abstract

A patient interface device () includes a patient sealing assembly () including a cushion () and a frame member (), and an adjustable forehead support assembly () provided at the distal end () of the frame member. The assembly includes an adjustment mechanism () coupled to a forehead cushion (), the adjustment mechanism including a housing (), a forehead cushion support member () having a base portion () and an elongated post member () extending from the base portion and received within the housing, and a locking member () structured to be selectively coupled to the elongated post member. In the locked condition, the locking member engages the elongated post member and prevents the elongated post member from moving relative to the housing, and in the unlocked condition the locking member does not engage the elongated post member such that the elongated post member and the housing are freely linearly movable with respect to one another.
