Abstract: A respiratory mask system includes a mask interface and a headgear assembly. The headgear assembly is adjustable and comprised of an elastic portion, a non-elastic portion and a restriction mechanism configured to provide a force resisting movement of the non-elastic portion when the elastic portion is extended. There is a support beam coupled to the non-elastic portion and extending along a portion of the headgear that is curved along its longitudinal extent. In this way particular seal modules can be comfortably fitted to a user and any blow off force is mitigated. A particular example of the respiratory mask system includes provision for removable attachment between the seal and a mask frame, the mask frame and a yoke of the headgear; and between a conduit and the mask frame.

Abstract: A headgear system and/or an interface assembly incorporating a headgear system that, in some configurations, is configured to transform from elasticated or “stretchy” behavior to “inelastic” behavior at least in response to normal or expected forces encountered during the intended therapy. In some configurations, upon fitment to the head of a user, the system automatically adjusts toward or to an appropriate size. A headgear portion or assembly for use in combination with a breathing apparatus in some configurations is at least substantially inelastic and is three dimensional in shape. The headgear portion or assembly can comprise a plastic core and a textile casing. The headgear, or part thereof, may also have integrally moulded labels, connectors, adjustment mechanisms and/or grips.

Abstract: A respiratory mask system is provided comprising a respiratory mask and a head engaging portion, wherein the head engaging portion is configured to couple to the respiratory mask to engage a wearer's head via a disengageable mechanism. The disengageable mechanism may comprise a linking member attached to the head engaging portion, a disengagement member attached to the respiratory mask and configured to receive the linking member, wherein the disengagement member is configured to be moveable between a first position and a second position, a control configured to allow a wearer of the mask to move the disengagement member towards the first position and one or more surfaces defined by the disengagement member and configured to exert a frictional force on the linking member.

Abstract: A mask assembly includes a mask interface and a headgear assembly. The mask interface includes a housing and a seal that seals around a user's nose and/or mouth in use. The headgear assembly secures the mask interface to the user's face in use. The headgear assembly can include a top strap, a rear section, and side arms. The top strap can be manually adjustable. The rear section can be temporarily expanded to allow for donning and/or doffing of the mask assembly. The side arms can be automatically adjustable.

Abstract: A ballooning patient interface has a frame that supports a scaling member. The frame and/or the scaling member is scoured to the head of a user with headgear, such as a strap. Various features of the sealing member improve comfort for the user in the nares of the users as well as on facial surfaces in contact with the seating member.

Abstract: This disclosure provides a directional adjustment unit for a headgear for a respiratory mask The directional adjustment unit provides an increased resistance to extension of one or more straps of the headgear when the headgear is under tensile forces, as compared to a lower resistance to retraction of the one or more headgear straps. The directional adjustment unit comprises a movable frictional engagement member comprising an aperture, wherein the aperture is arranged to receive a filament of a strap of the headgear therethrough, wherein the frictional engagement member in a first configuration provides a disengaged or pre-activated configuration with respect to the filament, and in a second configuration provides an engaged configuration with respect to the filament. Features are provided which improve the operation of such a directional adjustment unit.

Abstract: According to this disclosure there is provided various embodiments of directional adjustment unit for a headgear for a respiratory mask, comprising a housing, at least one frictional engagement member arranged to be movable with respect to the housing, the at least one frictional engagement member having an aperture extending therethrough for receiving a filament of a strap of the headgear therethrough, wherein the at least one frictional engagement member in a first movable configuration provides a disengaged configuration with respect to the filament, and in a second movable configuration provides an engaged configuration with respect to the filament. Also disclosed herein are various headgear, yoke assemblies, mask assemblies, mask frames and headgear filaments, some of which are for use with such a directional adjustment unit.
