Abstract
Official abstract text for this publication.
An inflatable face seal ( 1′; 30′ ) for a respiratory mask, the inflatable face seal comprising an annular air-tight hollow portion ( 12′; 40′ ) where a cross section through one section of the annular hollow portion ( 12; 40 ) comprises a bonded joint ( 11; 41 ) which joins two overlapping flanges ( 6,7; 35,36 ). The two flanges are bonded together such that an inwardly facing surface ( 10; 39 ) of a first flange ( 6; 35 ) of the two overlapping flanges is in contact with an outwardly facing surface ( 9; 38 ) of a second flange ( 7; 36 ) of the two overlapping flanges. In this way, the bond is strong and only exposed to shear stresses when the annular air-tight hollow portion is exposed to increased pressure.
