Abstract

See full text

A full-face cushion comprises a substantially triangularly shaped frame from which extends a membrane. The frame has a scalloped edge by which the cushion is affixed to a mask body to form a full-face mask. The membrane has an aperture into which the wearer's nose is received. The member is spaced away from the rim of the frame, and its outer surface is of substantially the same shape as the rim. Respective notches receive the bridge of the wearer's nose. The wearer's nose and lips are received through the aperture into the chamber within the mask body. The seal forming portion thus contacts both the surface of the wearer's nose and a portion of the wearer's face in the region between the bottom lip and the chin, and around the sides and over the bridge of the nose. The shape of the seal forming portion is particularly suited to effectively seal the difficult region of the facial contour that is the crease between the sides of the nose and the face.
