Abstract
A headgear for securing and positioning a mask suitable for the treatment of sleep disordered breathing is constructed from a composite including polyurethane foam. It includes a back portion with upper and lower straps connected to the back portion. The straps have relatively narrow strap ends the lower straps are displaced downward with respect to the back portion. A quick release mechanism near the front of the face attaches the headgear to the mask. Additional components can be attached to the straps to alter their elasticity and stiffness.

47. A headgear for securing and positioning a mask suitable for the treatment of sleep disordered breathing, comprising:
-
a back portion having an opening to receive an occiput of a patient'"'"'s head; and a pair of elongated first straps connected to the back portion on opposing sides of the back portion and extending away from the back portion;
each first strap having a loop portion positioned along an external surface of its length and a hook portion at a free end thereof for releasably attaching to the loop portion to attach the strap to the mask;wherein a width of the pair of first straps along the loop portion to which the hook portion releasably attaches is sufficiently wider than the hook portion that when the hook portion is attached to the loop portion, in use the strap shields a user'"'"'s face from contact with the hook portion, wherein a width of the loop portion varies along a length of the first pair of straps, and wherein each first strap angles downward to displace downward a length of each first strap with respect to the back portion. - View Dependent Claims (48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62)
