Abstract:
1. A chin support assembly adapted to be selectively coupled to a patient interface that includes a mask shell, a sealing member coupled to the mask shell, and a gas supply conduit coupled to the mask shell at an inlet opening, the chin support assembly comprising; a support member; an attaching member operatively coupled to the support member, wherein the attaching member is adapted to selectively couple the support member to the patient interface by selectively coupling to the patient interface; a chin support bracket operatively coupled to the support member; and a chin pad operatively coupled to the chin support bracket, wherein the attaching member, when coupled to the patient interface, extends downwardly from a portion of the mask shell below the inlet opening toward the chin support bracket, wherein the support member extends from the chin support bracket toward the mask shell, and wherein a distal end of the support member is moveably and adjustably coupled to a distal end of the attaching member in a manner wherein, when the attaching member is coupled to the patient interface, the support member is adjustable relative to the mask shell in a direction parallel to a plane in which the mask shell lies so that a position of the chin pad relative to the mask shell can be adjusted to control a distance between the chin pad and the mask shell.
