ABSTRACT:
In addition to protective helmets, a breathing protection is required time and again. This purpose is served by a protective breathing mask. It must be made possible to put the mask on in a simple way with one hand, but reliably and in combination with the protective helmet. To this end, the mask is provided with locking means comprising coupling hooks to be moved by means of spreading dogs. While pushing the dogs together, the coupling hooks are displaced outwardly, to spread apart at the end of this motion. Upon putting on the protective mask and releasing the hold of the spreading dogs, the hooks get clamped to the protective helmet where they engage catch seats to lock the mask to the helmet. The breathing mask is thus firmly held toward the face to be protected. The mask is removed in an equally simple way, by pushing the spreading dogs together.
