Abstract

The connection of a breathing mask to a safety helmet provides increased wearing comfort. A fastening mount (12) with circular arc-shaped inner contour (14) is provided, and the bracket for the breathing mask has a projection corresponding thereto. The projection is in contact with the inner contour (14) of the fastening mount (12), so that the bracket is displaceable in relation to the fastening mount (12) in a rotatingly movable manner.
