Respiratory mask assembly

A respiratory mask assembly for delivering breathable gas to a patient, comprising:

• a frame having an extended support arm with a housing provided on a free end of the support arm;
• a mask assembly cushion associated with the frame;
• a forehead support provided with a slider that is slidably received within a receiving space defined by the housing to move between extended and retracted positions, the slider being equipped with a forehead cushion that is structured to engage a patient's forehead;
• and
• an adjustment mechanism to allow linear movement of the forehead support in a direction substantially perpendicular to a longitudinal axis of the support arm, the adjustment mechanism including an actuator with only a single finger-operated push button to releasably lock the forehead support relative to the housing in one of a plurality of predetermined fixed positions,
• wherein the housing includes a front side and a rear side, the receiving space extending from the rear side of the housing, and the front side of the housing includes a closed configuration such that a free end of the slider is enclosed by the housing throughout movement between the extended and retracted positions.

A respiratory mask assembly for delivering breathable gas to a patient, comprising:

• a frame;
• a facial cushion engaged with the frame;
• a forehead support provided with a forehead cushion that is structured to engage a patient's forehead, the forehead support being slidably mounted to the frame to allow linear movement of the forehead support;
• and
• an adjustment mechanism to allow selective adjustment of the forehead support relative to the frame in a plurality of predetermined fixed positions, the adjustment mechanism including an actuator with only a single finger-operated push button,
• wherein the frame includes a main body, a support arm extending substantially vertically upwards from the main body, and a housing provided to a free end of the support arm, and the forehead support includes a slider that is slidably received within a receiving space located inside the housing to move between extended and retracted positions,
• wherein the forehead support is slidably mounted for linear, substantially horizontal movement which is substantially perpendicular to the substantially vertically extending support arm, and
• wherein the housing includes a forwardly facing side and a rearwardly facing side, the receiving space extending from the rearwardly facing side of the housing, and the forwardly facing side of the housing includes a closed configuration.
