Abstract
Mounted in the front wall region of a hood is a curved replaceable facepiece lens. In order to obtain a gas-tight joint between the rigid component constituting the facepiece lens and the flexible garment material, as well as obtaining a distribution of the stresses which occur in the region of the junction between the facepiece lens and the garment material, a spherically-bent frame is enclosed by an overlapping cloth frame in the region of the opening for the facepiece lens and forms a firm connecting rim. Located as a seal between the said connecting rim and the rigid facepiece lens is an elastic coupling gasket.
