HEADGEAR WITH LOCK DISENGAGEMENT MECHANISM

A directional lock assembly for a respiratory mask headgear comprising a housing; a first and a second lock element; a core member; the housing comprising a first end wall, a second end wall, a first side wall, a second side wall, and wherein the side walls extend between the end walls; the housing further comprising first and second chambers, configured to house the first and second lock elements respectively, the first end wall, second end wall, and the first and second lock elements comprising openings for the core member to pass through, the openings in the first end wall and second end wall being aligned with each other, wherein each of the first and second chambers comprise a pair of lock element retainers that are aligned on opposing side walls of the housing and are configured to pivotally retain the first and second lock elements within the respective first or second chambers, wherein the first and second lock elements are configured to pivot between a first position and a second position, wherein in the first position the openings in the first end wall, second end wall, and the first and second lock elements are aligned, and in the second position the path of the core member through the directional lock is non-linear or tortuous and movement of the core member through the directional lock is restricted, and a disengaging member which is movable between an unactuated position and an actuated position, wherein when the disengaging member is in the unactuated position, the disengaging member does not block the first and second lock elements from moving between the first position and second position, and wherein when the disengaging member is in the actuated position, the disengaging member blocks the first and second lock elements from moving to retain the first and second lock elements in the first position.
