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.
Claims37
Headgear for a respiratory interface, comprising:
- a rear part of the headgear,
- a pair of upper side straps,
- a pair of lower side straps, and
- a top strap,
- composed of multiple separate sections of material joined to form the headgear, said separate sections comprising:
- two upper side strap parts which form the upper straps, each including a curved rear portion, joined at the rear of the headgear to also form an upper rear strap,
- a lower rear strap part which forms a lower rear strap;
- and
- two lower side strap parts which form the lower side straps and are joined to the lower rear part on left and right sides;
- and
- wherein the headgear comprises at least four different levels of resilient extensibility or stretchability in at least four different parts or straps of the headgear.

- wherein the rear part or at least a lower portion of the rear part of the headgear and top strap have relatively highest stretchability, the pair of upper side straps are stretchable but have relatively less stretchability than the rear part of the headgear and top strap, and the pair of lower side straps have least stretchability or are substantially non-stretchable, or
- wherein the upper side straps and top strap have relatively highest stretchability, the rear part or at least a lower portion of the rear part of the headgear has relatively less stretchability than the upper side straps and the top strap, and the pair of lower side straps has least stretchability or is substantially non-stretchable.
