摘要：
A headgear assembly for stabilizing and positioning a respiratory mask assembly on a patient’s head, comprising: a pair of upper side straps (16) and a pair of lower side straps (24)； a rear portion including an upper strap, a lower strap, and an intermediate strap arrangement between the upper and lower straps of the rear portion； and a stiffener (46) positioned on the rear portion, wherein the intermediate strap arrangement includes a pair of upper straps (32) angled with respect to the upper strap of the rear portion, a pair of lower straps (34) angled with respect to the lower strap of the rear portion, and a cross-bar strap (36) that extends between the upper and lower straps of the intermediate strap arrangement, wherein the stiffener includes a body (48) that extends along the cross-bar strap to assist in engagement of the cross-bar strap with the patient’s occipital bone, wherein the stiffener includes a pair of arm members (50) that extend along respective lower straps of the intermediate strap arrangement to resist movement between the cross-bar strap and the lower straps to prevent the lower straps from impinging on an inferior portion of the patient’s ear, and wherein the body has a width that is greater than a width of the arm members.
