Abstract
The equipment, for use by a pilot, is intended to provide the wearer with breathing gas under a pressure greater than ambient pressure. It comprises a mask having a rigid shell provided with fastening straps for holding the mask on the head, with a coupling for feeding breathing gas under pressure, and with a face cover of elastomer material terminated by an internal sealing lip for pressing against the face. The lip is connected to a front portion of the face cover that is secured to the shell by at least one thin deformable fold. Resilient elements are provided along the fold to exert a force that varies little with the amount of deformation and press the lip against the face.
