Abstract
A harness assembly (40) for a nasal mask (42) for communicating breathable gas to a patient'"'"'s airways, for example in the administering CPAP or like breathable gas delivery treatments. The harness assembly (40) includes a cap portion (44) adapted to engage, in use, the occipital region of the skull (43). In one form, the cap portion (44) includes a D-shaped coupling (48) at each end and the harness assembly (40) includes a pair of upper (52) and lower (54) straps, each of the straps (52, 54) extending between one of the D-shaped couplings (48) and the nasal mask (42). The harness assembly (40) grips the head (43) in a region substantially fixed relative to the face and, as such, tension of the straps (52, 54) is not substantially affected by head movement. Couplings of other shapes are also discussed.
