Abstract
Protective breathing equipment comprises a breathing mask provided with a regulator for connection to a source of pressurized breathing gas and a harness having at least one extensible strap whose ends are connected to the mask and which includes an element that is temporarily inflatable by the pressurized gas to lengthen the strap until it is large enough to enable the user to engage the harness on the head, and exhaustible to allow the strap to press to press the mask against the face. The extensible strap is connected to the face-piece by at least one mechanical member of length that is adjustable by the user while wearing the equipment.
