Abstract
Applicants have disclosed an “Articulating Headgear Connector for Respiratory Masks” which allows three-dimensional movement of the headgear connector to alleviate the mechanical forces incurred from a wearer's head movement, and thus maintain an effective seal. In the preferred embodiment, the invention comprises: a CPAP mask having a plastic shell; the mask has a stub tube extending outwardly from the shell; a headgear connector mounted loosely onto the stub tube; a T-shaped nib on the elbow guides the headgear's movement; whereby the headgear connector can slide forward on the stub tube (i.e., move along the Z axis), guided by the nib; and, whereby the headgear connector can rock (i.e., about the X-Y axes) and its sides seesaw on the stub tube (i.e., along the Z-axis), with the amount of rotation and seesawing limited by the nib.
