    • A nasal cushion (30) comprises a substantially triangularly shaped frame (32) from which extends a membrane (34). The frame (32) has a scalloped edge (36) by which the cushion (30) is affixed to a mask body. The membrane (34) has an aperture (38) into which the wearer's nose is received. The membrane (34) is spaced away from the rim (40) of the frame (32), and its outer surface (41) is of substantially the same shape as the rim (40). Respective notches (42, 44) receive the bridge of the wearer's nose. The wearer's nose is received through the aperture (38) into the chamber within the mask body (46). The seal forming portion (45) thus contacts both the surface of the wearer's nose and a portion of the wearer's face in the region between the base of the nose and the upper lip, and around the sides and over the bridge of the nose. The shape of the seal forming portion (45) 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.
    • 鼻垫(30)包括基本上三角形的框架(32),膜从框架(32)延伸出来。 框架(32)具有扇形边缘(36),通过该扇形边缘将衬垫(30)固定到面罩主体。 膜(34)具有孔(38),佩戴者的鼻子被接纳到该孔中。 膜(34)与框架(32)的边缘(40)间隔开,并且其外表面(41)具有与边缘(40)基本相同的形状。 切口(42,44)接纳穿戴者鼻子的桥梁。 佩戴者的鼻子通过孔(38)被容纳到面罩主体(46)内的腔室中。 密封形成部分45因此在鼻子的基部和上唇之间的区域中以及在鼻子的两侧和上方接触穿戴者鼻部的表面和穿着者脸部的一部分。 密封形成部分(45)的形状特别适合于有效地密封作为鼻部和脸部两侧之间的折痕的面部轮廓的困难区域。
