Abstract
A forehead support for a respiratory mask. The forehead support includes a pair of arms. The arms are each adapted to locate a forehead cushion. The arms are also adapted to pivot relative to each other. The arms are also selectively lockable at two or more angular positions relative to each other. The forehead support can thus be adjusted to suit the facial topography of the wearer of the respiratory mask.

21. A forehead support for a respiratory mask comprising:
-
a first arm; a second arm adjustably coupled to the first arm; and a locking mechanism configured to lock the first and second arms in at least first and second fixed angular orientations, the locking mechanism being adjacent an axis and the first and second arms being pivotable relative to each other around the axis, wherein the first and second arms engage each other at the locking mechanism. - View Dependent Claims (22)
