Abstract (en)
The face seal (1) for protective masks presents substantially a bellows structure (4) and is asked to surround the whole face of the user; the bellows structure (4) allows the face seal (1) to adapt itself easily to physically different faces, reducing the number of sizes in which the mask utilizing such face seal (1) has to be realized.
