ABSTRACT:
A ventilation mask has a base, a hose connection, and at least one sealing element and is provided with a forehead support. The forehead support is arranged in such a way that it can be positioned relative to the base of the mask. A connecting device that couples the forehead support with the base of the mask is flexible. The connecting device is arranged so that it can be moved relative to a guide in such a way that the connecting device projects a predeterminable distance from the guide and can be locked in at least two different positions relative to the guide.
