Abstract
A strap for respirator masks comprises a head strap piece, made from elastically flexible synthetic material, with a strap fixing piece and a head plate with a greater wall thickness than the attached head straps. A neck strap, connected to the mask at two fixing points and an extending temple strap, which may be introduced in a detachable and length adjustable manner into fixing clips attached to the head straps, are fixing to the strap fixing piece. The head strap piece thus consists of a straight and a curved piece. The crown-shaped embodiment with the elastic temple band is associated with good fitting and wearing properties and low maintenance requirements.
