Abstract
In a respirator mask in which the visor panels can be covered by light-absorbing supplementary panels, first and second snap-in hooks are molded onto opposite sides of the visor panel and a stop is molded onto a corner section to form a guide pocket. The outer contour lines and the convexity of the visor panel and the supplementary panel are identical. To attach the flexurally elastic supplementary panel, it is first fastened in the guide pocket and on the first snap-in hook. Then the opposite side is locked into the second snap-in hook after flexing the supplementary panel.
