摘要：
A mask assembly has a cushion 1216 which is attached to a frame 1214 by a flexible lip on the cushion engaging in a recess between outer and inner walls 1220,1222. Inner wall 1222 has a protrusion 1223 to provide interference with and retain the cushion 1216 to the frame 1214. The protrusion 1223 is angled to guide the lip into the recess.
