Definitions

  • the invention has for its object to improve a respirator in such a way that the mask body allows a low-distortion view through the transparent part of the mask body with the largest possible usable field of view and has a small dead space volume.
  • a favorable dead space volume for the mask body results if the radius of curvature of a meridian section plane of the mask body running along the axis of symmetry is greater than 80 millimeters, the dead space volume decreasing with increasing radius of curvature.
