Abstract

The invention relates to a nasal breathing mask and a mask cushion for a nasal breathing mask. The nasal breathing mask comprises a mask cushion and a mask-holding part, which is connected to a hose connection for a breathing hose, and at least one strap for positioning the breathing mask on the face, in particular on the nose, of a user. Together with the mask part, the mask cushion for the nasal breathing mask forms an inner space for accommodating at least the nose of the user. The mask cushion consists of flexible material with a sealing lip, the sealing lip, when the breathing mask is being used, bearing in a sealed manner on the face of the user by means of a part of its outer surface and, in the process, being deformed. In the bearing part, the sealing lip delimits an opening to the inner space by means of an edge and may have a thickened section. Furthermore, the mask cushion may have an inner supporting wall and a sealing lip wrapped inwardly around the supporting wall, the sealing lip running on that side of the supporting wall which is remote from the inner space and being spaced apart from this wall, and the supporting wall being provided with webs which, when the breathing mask is being used, reduce the deformation thereof.
