Abstract: A forehead pad for a breathing mask includes a substantially dimensionally stable first wall element and an elastomer second wall element coupled to the first wall element. The second wall element has a contact zone adapted to contact a surface of a user in use. The first and second wall elements define a filling-material-receiving chamber adapted to receive a filling material.
Abstract: A forehead-contacting device for a breathing mask includes a support element made from an elastomer material. The support element forms a support face which in an application position is adapted to seat on a forehead area of a user. The support element includes a jacket that defines a hollow chamber adapted to be filled with a viscous medium.

Abstract: A method and a device are provided for detecting the respiratory activity of a person and for controlling the time progression of breathing gas pressure, especially in accordance with physical parameters and considering parameters indicating the momentary physiological condition of the breathing person. The device for detecting the respiratory activity of a person has at least one sensor that provides a first signal indicating the breathing gas flow, wherein at least one signal processing device is provided for processing the first signal. The signal processing device is configured in such a way that said device determines a reference-relation on the basis of the first signal detected during a first time interval. On the basis thereof, the device determines a correlation-relation between the reference-relation and the first signal.
