Abstract

Masca de protectie a respiratiei, conform inventiei, este alcatuita dintr-un corp de baza prevazut cu o rama de etansare si o portiune mai mare decît garnitura pe care sunt fixate cinci lame trapezoidale pentru fixarea unor benzi de sustinere, muchiile laterale ale lamelor fiind de lungimi diferite avînd o forma rotunjita la racordul cu portiunea sus-mentionata, forma si lungimea lamelor trapezoidale nepermitînd deformarii ale conturului ramei de etansare, indiferent de pozitia benzilor de fixare, în acest fel masca putînd fi usor montata pe fata purtatorului. Masca, conform inventiei, permite o etanseitate buna pe fata indiferent de pozitia fortelor de tractiune în benzi, iar producerea lor nu mai este legata de un anumit mod de asezare a benzilor.According to the invention, the respiratory protection mask consists of a base body provided with a sealing frame and a larger portion than the gasket on which there are fixed five trapezoidal blades for securing supporting strips, the side edges of the blades being of different lengths having a rounded shape at the connection with the above-mentioned portion, the shape and length of the trapezoidal blades not allowing the deformation of the contour of the sealing frame, regardless of the position of the fastening strips, thus the mask can be easily mounted on the wearer's face. According to the invention, the mask allows for a good seal on the face regardless of the position of the belt traction forces and their production is no longer related to a particular way of seating the bands.
