Abstract: Headgear for a respiratory interface comprising multiple separate sections of material joined to form the headgear and different levels of resilient extensibility or stretchability in at least four different parts or straps of the headgear.

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, for use in combination with a breathing apparatus, has a plastic or elastomer core and a fabric or textile casing. The headgear, or portions thereof, may also include a length adjustment arrangement that permits adjustment of a length of a section of the headgear. The length adjustment arrangement can comprise overlapping strap portions of the headgear. In some configurations, the overlapping strap portions can be covered by a sleeve. The sleeve can be secured to the headgear by overmolded end caps. A nasal respiratory interface can include a frame having a front surface, a rear surface, and an aperture extending from the front surface to the rear surface. The frame can have an oval form with a truncated height portion. The interface can also include a seal for a nasal pillow. The seal can be attached to the frame.

Abstract: A respiratory mask system comprising a mask interface comprising a frame for a headgear assembly. The frame comprises a body comprising a first surface and a substantially opposing second surface. The body further comprises a gas inlet and optionally an outlet vent. The gas inlet may be substantially elliptical in shape. The frame may comprise a recessed region for receiving yoke of a headgear assembly to attach the headgear to the mask interface. The respiratory mask system may also comprise a yoke for attaching to the frame.

Abstract: A headgear assembly for retaining a respiratory mask on a user's face includes arrangements or components that allow for variation in a size of the headgear assembly. In some configurations, the headgear assembly includes one or more hubs, each of which are configured to connect a top and rear strap together. The size of the headgear assembly can be determined by the size or configuration of the hub. In other configurations, the headgear assembly comprises one or more spacer elements within one or more straps of the headgear. The size of the headgear assembly can be determined by the size of the spacer element or a relative position between the strap and the spacer element.
