A breathing mask arrangement includes a mask frame, a sealing device provided to the mask frame, a forehead support device movably mounted to the frame for adjustable movement with respect to the frame, and a rotatable adjustment knob operatively associated with the forehead support device such that rotative movement of the adjustment knob is adapted to cause relative movement between the forehead support device and the frame.
