Abstract
A headgear for a patient interface, such as a respiratory interface, includes a plurality of panels which are lapped against each other. The panels define lapped parts of the headgear where panels overlap and/or underlap each other, and non-lapped parts of the headgear where a panel or panels are not lapped by another panel. The panels at the lapped regions are bonded to each other by an adhesive, such as a hot-melt adhesive. By combining panels having different properties, interfaces between panels having different lapping configurations, and by controlling the properties such as extensibility and stiffness of the adhesive when set a headgear may be provided location-specific features and properties.

A headgear for a patient interface, the headgear comprising:
- a rear portion configured for location at a rear position of a user's head in use;
- a pair of upper side strap portions, each of the pair of upper side strap portions comprising a first end portion configured to connect to the patient interface and a second end portion connected to the rear portion;
- a pair of lower side strap portions, each of the pair of lower side strap portions comprising a first end portion configured to connect to the patient interface and a second end portion connected to the rear portion;
- a pair of crown strap portions connected to a respective one of the upper side strap portions, wherein the pair of crown strap portions and the rear portion form a closed rear loop in use;
- the rear portion comprising an upper peripheral edge extending between the pair of crown strap portions;
- a lower peripheral edge extending between the pair of lower side strap portions;
- and a pair of lateral peripheral edges extending between respective upper and lower strap portions and defining ear loops configured to be positioned behind the ear of the user in use and,
- wherein the rear portion is formed from individual fabric panels comprising a first extensible fabric panel and a second fabric panel, wherein the second fabric panel is bonded to the first extensible fabric panel forming a laminated panel layup having at least one lapped region and at least one unlapped region, the at least one unlapped region having an area defined by a convex upper edge and a concave lower edge, and
- wherein the at least one lapped region of the laminated panel layup is less extensible than the at least one unlapped region.
A headgear for a patient interface, the headgear comprising:
- a rear portion configured for location at a rear position of a user's head in use;
- a pair of upper side strap portions, each of the pair of upper side strap portions comprising a first end portion configured to connect to the patient interface and a second end portion connected to the rear portion;
- a pair of lower side strap portions, each of the pair of lower side strap portions comprising a first end portion configured to connect to the patient interface and a second end portion connected to the rear portion;
- the rear portion comprising a first fabric panel and a second fabric panel bonded to the first fabric panel forming a laminated panel layup having a lapped region formed by the first and second fabric panels, and at least one unlapped region formed by the first fabric panel, the at least one unlapped region having an area defined by a convex upper edge and a concave lower edge.
A rear portion of a headgear for use with a patient interface, the rear portion comprising:
- a laminate of individual fabric panels, the laminate of individual fabric panels comprising:
- a first fabric panel comprising a first upper peripheral edge, a first lower peripheral edge, and a pair of first lateral peripheral edges;
- and
- a second fabric panel comprising a second upper peripheral edge, a second lower peripheral edge, and a pair of second lateral peripheral edges,
- where the second fabric panel is bonded to the first fabric panel forming a laminated panel layup having at least one lapped region and at least one unlapped region, the at least one unlapped region being located between the first lower peripheral edge and the second lower peripheral edge and defining an area having a convex upper edge and a concave lower edge, wherein the concave lower edge is coextensive with at least a portion the first lower peripheral edge.
A rear portion of a headgear for use with a patient interface comprising a laminate of individual fabric panels, the laminate of individual fabric panels consisting essentially of:
- a first fabric panel comprising a first upper peripheral edge, a first lower peripheral edge, and a pair of first lateral peripheral edges;
- and
- a second fabric panel comprising a second peripheral upper edge, a second peripheral lower edge, and a pair of second lateral peripheral edges,
- wherein the second fabric panel is bonded to the first fabric panel forming a laminated panel layup having at least one lapped region and at least one unlapped region, the at least one unlapped region being located between the first lower peripheral edge and the second lower peripheral edge and defining an area having a convex upper edge and a concave lower edge.
