<p>A mechanism 10 for mounting a pilot's breathing mask 2 to a pilot's helmet comprises a rotatable member (14, Fig 2) rotatably mountable to a pilot's mask and, first and second tensile members 32, 34 each having a first end and a second opposite end. The first end of at least one tensile member is engaged with the rotatable member and the opposite end of each tensile member is configured to be coupled to an attachment point on a respective side of a pilot's helmet. The rotatable member is connected to an actuator 22 to enable a pilot to rotate the rotatable member to draw in the at least one tensile member engaged with the rotatable member and thereby adjust the length of the or each tensile member between an attached mask and a pilot's helmet to adjust the tension with which the attached mask is held against a pilot's face. At least one hollow guide member 26 is provided through which the at least one tensile member engaged with the rotatable member extends from the rotatable member toward a respective side of the pilot's helmet.</p> |
