Abstract (en)
[origin: EP0463383A2] A breathing protection mask, with a breathing filter and a bellows which seals the mask interior in relation to the environment and extends in the manner of a rigid collar around the breathing filter at its end facing the mask interior, is to be improved in such a manner that changing the breathing filter is made easier. To achieve this aim, it is envisaged that the collar (7) is continued to an elastic sleeve (8) enclosing the breathing filter (2) almost completely, the breathing filter (2) being insertable into the sleeve (7), or removable therefrom, with the sleeve (8) folded back. <IMAGE>
