The magnetic fastener component is provided between a distal end of the strap and an anterior portion of the positioning and stabilising structure, and can be formed to the strap. Methods of manufacturing a positioning and stabilising structure which has at least one strap, where the methods attach or provide a magnetic fastener component to the strap. In forms, the magnetic fastener component is formed to the strap e.g. when forming the strap. ## Claims ### Claim 1 A positioning and stabilising structure for a patient interface system, comprising a rear strap assembly, at least one strap which extends away from the rear strap assembly and along a side of the patient's face, wherein the at least one strap has a distal end, and a first strap fastener that comprises a magnetic fastener component provided to the at least one strap and that is positioned between the distal end and the rear strap assembly. ### Claim 2 A positioning and stabilising structure for a patient interface system, comprising at least one strap and a strap fastener half, wherein the strap fastener half comprises a magnetic fastener component which is formed to the at least one strap. ### Claim 3 A positioning and stabilising structure for a patient interface system, comprising at least one strap and a strap fastener half which is permanently attached to the positioning and stabilising structure, wherein the strap fastener half comprises a magnetic fastener component, and further wherein the strap fastener half is configured to in use engage with a corresponding fastener half on a patient interface to attach the positioning and stabilising structure to the patient interface. ### Claim 4 (depends on 1) The positioning and stabilising structure as claimed in claim 1, comprising a first strap and a second strap, wherein the first strap comprises a first strap fastener half and the second strap comprises a second strap fastener half, and further wherein the first strap fastener half and the second strap fastener half each comprises a magnetic fastener component. ### Claim 5 (depends on 4) The positioning and stabilising structure as claimed in claim 4, wherein the magnetic fastener components are both permanently attached to, or formed to, the respective strap. ### Claim 6 (depends on 4) The positioning and stabilising structure as claimed in claim 4, wherein at least one of the first strap fastener half and the second strap fastener half comprises an insertion portion configured to in use be inserted into a corresponding receiving portion of a patient interface fastener half. ### Claim 7 (depends on 1) The positioning and stabilising structure as claimed in claim 1, wherein the strap fastener half is attached to a first layer of material. ### Claim 8 (depends on 7) The positioning and stabilising structure as claimed in claim 7, wherein the first layer of material is a textile material. ### Claim 9 (depends on 7) The positioning and stabilising structure as claimed in claim 7, wherein the strap(s) have a multi-layer construction comprising the first layer of material and at least one additional layer of material. ### Claim 10 (depends on 9) The positioning and stabilising structure as claimed in claim 9, wherein the multi-layer construction comprises at least one additional layer and wherein the additional layer of material is a textile material. ### Claim 11 (depends on 9) The positioning and stabilising structure as claimed in claim 9, wherein the multi-layer construction comprises a layer of foam material. ### Claim 12 (depends on 10) The positioning and stabilising structure as claimed in claim 10, wherein the multi-layer construction comprises a plurality of layers that are laminated or glued together. ### Claim 13 (depends on 1) The positioning and stabilising structure as claimed in claim 1, wherein the strap has a patient contacting surface, and wherein the strap fastener component is located on the distal side of the patient contacting surface from the patient's face in use. ### Claim 14 (depends on 4) The positioning and stabilising structure as claimed in claim 4, further comprising a third strap and a fourth strap. ### Claim 15 (depends on 14) The positioning and stabilising structure as claimed in claim 14, wherein the first strap and the second strap provide a pair of lower straps for the positioning and stabilising structure and the third strap and the fourth strap provide a pair of upper straps for the positioning and stabilising structure. ### Claim 16 (depends on 14) The positioning and stabilising structure as claimed in claim 14, wherein the third strap and the fourth strap each comprises a connector configured to in use releasably attach the positioning and stabilising structure to a patient interface. ### Claim 17 (depends on 16) The positioning and stabilising structure as claimed in claim 16, wherein the connectors on the third strap and the fourth strap each comprises a magnetic fastener component configured to in use engage with a corresponding magnetic fastener component on a patient interface. ### Claim 18 A treatment system, comprising a patient interface to deliver a supply of pressurised breathable gas to one or more of a patient's airways, and a positioning and stabilising structure; wherein the positioning and stabilising structure comprises at least one strap having a strap fastener half, wherein the strap fastener half comprises a magnetic fastener component which is formed to the at least one strap, and the patient interface comprises a patient interface fastener half which includes a magnetic fastener component, and further wherein in use the magnetic fastener components together releasably attach the at least one strap to the patient interface. ### Claim 19 A method of manufacturing a positioning and stabilising structure for a patient interface system, comprising the following steps in any order: selecting a first layer of material; positioning a magnetic fastener component and the first layer of material relative to each other; attaching the magnetic fastener component to the first layer of material. ### Claim 20 (depends on 19) The method as claimed in claim 19, wherein the step of attaching the magnetic fastener component to first layer of material involves forming at least a portion of a strap for the positioning and stabilising structure. ### Claim 21 (depends on 20) The method as claimed in claim 20, wherein forming the strap involves laminating at least two layers of material to each other to form a multi-layer structure. ### Claim 22 (depends on 21) The method as claimed in claim 21, wherein laminating the at least two layers of material to each other forms the magnetic fastener component to the strap. ### Claim 23 (depends on 19) The method as claimed in claim 19, including the step of shaping the strap to have a desired shape. ### Claim 24 (depends on 23) The method as claimed in claim 23, wherein the step of shaping the strap includes cutting. ### Claim 25 (depends on 19) The method as claimed in claim 19, including the step of attaching the strap to another component of the positioning and stabilising structure. ### Claim 26 (depends on 25) The method as claimed in claim 25, wherein the step of attaching the strap to another component involves sewing to create a joint.
