Abstract
The invention relates to a head harness for a respirator which comprises a head plate ( ) that is elastic in the X direction and that is substantially nonelastic in the Y direction. Front straps ( ), temple straps ( ) and neck straps ( ) are fastened to the head plate, only the temple and the neck straps being extensible. The strap buckles ( ) provided for fastening the front and temple straps to the mask base are rigidly adjusted according to the head size so that the mask is already correctly positioned and preliminarily fixed when put on and only the neck strap has to be readjusted. The head harness can be adapted to different head shapes and sizes and allows for a high wearing comfort. The respirator can be quickly and easily put on.
