Abstract
A breathing mask is joined with a head fastening device that has at least one headstrap and at least one neckstrap. The headstrap and the neckstrap are connected with each other in the area of their extensions away from the breathing mask. The headstrap is fastened to the breathing mask at the top, and the neckstrap is fastened to the breathing mask at the sides in the orientation of the breathing mask when it is being worn. Regions of the neckstrap that are located next to the breathing mask are connected with one another by a chinstrap. The chinstrap extends essentially in the longitudinal direction of the neckstrap. End segments of the neckstrap, which are arranged between the breathing mask and the places at which the neckstrap is connected with the chinstrap, run towards the breathing mask at an angle of inclination relative to the chinstrap, so that they move farther and farther away from the chinstrap as they approach the breathing mask.
