Abstract: A headgear assembly for a full-face under-nose respiratory mask can include a flexible headgear connector element. A free end of each of upper straps of the headgear is coupled to the headgear connector element, which is configured to extend laterally across and be removably fastened to a frame of the respiratory mask below a tip of a user's nose. A respiratory mask assembly can include a bias vent in communication with a cushion module and configured to allow air to be exhausted from the cushion module through the bias vent. The bias vent can be provided with a diffuser including a diffuser material configured to extend over the bias vent. The diffuser material provides a tortuous air path from the bias vent through the diffuser. The bias vent and/or the diffuser can be provided on various components of the assembly.

Abstract: In some embodiments there is provided a headgear assembly for a full-face under-nose respiratory mask comprising a strap assembly including a rear panel, a crown strap, a pair of opposing upper side straps, and a pair of opposing lower side straps. The assembly further comprises a flexible headgear connector element, wherein a free end of each of the upper straps is coupled to the headgear connector element, and wherein the headgear connector element is configured to extend laterally across and be removably fastened to a frame of the respiratory mask below a tip of a user's nose. There is also provided a respiratory mask assembly comprising a mask frame and a cushion module, the mask frame comprising a breathing gas inlet configured to receive a supply of breathable gas and to deliver the breathable gas to the cushion module, the cushion module being configured to form a seal with a user's face.
