CS199436B1 - Sealing rim of protective respirator - Google Patents

Abstract

Breathing mask face contour sealing arrangement consists of a sealing lip (2) moulded onto the mask body (1). The lip is concave inwards between the temporal bones, flat at the cheeks but convex in the chin part. Preferably the concave part of the sealing lip should have a radius equal to the width of the lip. The lip should be divided into a straight or flat part and a concave part, each being half of the lip width.
