1. A respiratory mask assembly for treatment of sleep disordered breathing, the respiratory mask assembly comprising:
a shell; and
a cushion provided the shell,
wherein the shell is relatively harder than the cushion,
wherein the shell and the cushion form a cavity pressurizable to a therapeutic pressure,
wherein the cushion includes:
a face contacting portion including an upper face contacting region adapted to form a seal along a region of a patient's nose and a lower face contacting region adapted to form a seal along a region of a patient's mouth,
a non-face contacting portion supported by the shell,
a gusset portion provided to at least a section of the cushion between the face contacting portion and the non-face contacting portion, the gusset portion providing a decoupling joint between the face contacting portion and the shell,
wherein, when seen in cross-section:
the gusset portion includes a hanging portion that hangs over an adjacent exterior surface of the cushion, and
the gusset portion includes a first end adjacent to the face contacting portion and a second end adjacent to the non-face contacting portion, and the first end is offset radially outwardly from the second end,
wherein the gusset portion includes only a single gusset,
wherein the single gusset includes a first gusset wall that joins the face contacting portion at the first end, a second gusset wall that joins the non-face contacting portion at the second end, and a tip section that interconnects the first gusset wall and the second gusset wall,
wherein the tip section is positioned radially outwardly with respect to the non-face contacting portion,
wherein the tip section is offset radially outwardly from the first end and the second end, and
wherein a radial offset between the tip section and first end is greater than a radial offset between the first end and the second end.
