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.
