<p>A mechanism for mounting a pilot's breathing mask 2 to a pilot's helmet comprises a rotatable member 14 rotatably mountable to a pilot's mask 2 and first and second tensile members or straps 32, 34 each having a first end and a second opposite end. The first end of at least one tensile member 32, 34 is engaged with the rotatable member 14. The opposite end of each tensile member 32, 34 configured to be coupled to an attachment point on a respective side of a pilot's helmet. The rotatable member 14 is connected to an actuator 22 to enable a pilot to rotate the rotatable member 14 to draw in the at least one tensile member 32, 34 engaged with the rotatable member 14 and thereby adjust the length of the or each strap or tensile member 32, 34 between an attached mask 2 and a pilot's helmet to adjust the tension with which the attached mask 2 is held against a pilot's face.</p> |
