Abstract
A forehead support for a mask assembly includes a frame connector provided to a mask frame, a forehead cushion support movably mounted to the frame connector for generally linear movement between retracted and extended positions with respect to the frame connector, and an adjustment knob movably mounted to the frame connector and threadably engaged with the forehead cushion support such that turning movement of the adjustment knob causes the forehead cushion support to be moved between the retracted and extended positions. The adjustment knob, forehead cushion support, and frame connector are constructed and arranged such that over-rotation of the adjustment knob beyond the extended position of the forehead cushion support is adapted to release the adjustment knob from the forehead cushion support and the frame connector.
