POSITIONING AND STABILISING STRUCTURE WITH PATIENT CONTACTING PORTIONS

Abstract: a positioning and stabilising structure is configured to hold a seal-forming structure of a patient interface in a therapeutically effective position on the patient's head. the positioning and stabilising structure comprises a tie which is constructed and arranged so that at least a portion overlies a region of the patient's head superior to an otobasion superior, wherein a portion of the positioning and stabilising structure extends around a back of the patient's head. a flexible portion of the positioning and stabilising structure comprises at least one patient contacting portion which is configured to contact the patient's check. the coefficient of friction between at least a portion of the patient contacting portion and the patient's skin is higher than the coefficient of friction between an adjacent portion of the positioning and stabilising structure and the patient's skin.
