摘要：
A respiratory mask includes a frame including a breathable gas port, wherein the frame defines an inner chamber to receive at least one of a wearer's nasal region and mouth, and a cushion including a flange connected to the frame, an inner rim defining an opening to the inner chamber of the frame, and a sealing portion disposed between the flange and the inner rim to contact the wearer's face. The sealing portion includes a nasal seal section to span a wearer's face above the wearer's nares, side seal sections extending from each side of the nasal seal section on both sides of the wearer's mouth, and a chin seal section that extends between the side seal sections, wherein the chin seal section is upwardly curved in an arch to follow the chin's bony contour.
