WlJAT IS CLAIMED IS:
1. A cushion tbr a respiratory mask assembly comprising a frame-cormecting
portion, a face-contacting portion, and a gusset portion disposed between and joining said
flame-connecting and face-contacting portions, wherein the gusset portion includes at
least one perimetrical region which includes a laterally projecting exterior gusset section
and a laterally projecting interior gusset section.
2. The cushion as in claim 1, wherein the gusset portion has said laterally
prqjecting exterior and interior gusset sections about the entire perimeter to the gusset
portion so as to establish a substantially constant widthwise dimension about said entire
perimeter.
3. The cushion as in claim 1, wherein file gusset portion includes said laterally
projecting exterior and interior gusset sections along a lower perimetrical region thereof.
4. The cushion as in claim 1, wherein the gusset portion has a widthwise
dimension which varies about a perimeter thereof.
5. The cushion as in claim 1, wherein the gusset portion has a minimum
widthwise dimension at an upper perimetrical region thereof, a maximum widthwise
dimension at a lower perimetrical region thereof, and widthwise transitions joining said
upper and lower pefimetrical regions thereof.
6. The cushion as in claim 5, wherein the gusset portion has substantially zero
widthwise dimension at said upper perimetrical region thereof.
7. The cushion as in claim 5, wherein said widthwise transitions are
curvilinear.
8. The cushion as in claim 5, wherein the widthwise transitions are linear.

9. The cushion as in claim 5, wherein each said minimum and maximum
width~vise dimensions is substantially constant along said upper and lower perimetrieal
regions, respectively.
10. A cushion for a respiratory mask comprising a frame-connecting portion, a
t~ace-contacting portion, and a gusset portion disposed between and joining said frame-
connecting mad face-contacting portions, wherein said gusset portion has a perimeter
having a widthwise dinaension which varies between at least one region and another
perimetrical region thereof.
11. The cushion as in claim 10, wherein the gusset portion has a minimm~a
widthwise dimension at an upper perimetrical region thereof, a maximum widthwise
dimension at a lower perimetrical region thereof, and widthwise transitions joining said
upper and lower perimetrical regions thereof.
12. The cushion as in claim 11, wherein the gusset portion has substantially
zero widthwise dimension at said upper perimetrical region thereof.
13. The cushion as in claim 11, wherein said widthwise transitions are
Curvilinear.
14. The cushion as in claim 11, wherein the widthwise transitions are linear.
15. The cushion as in claim 11, wherein each said minimum and maximum
widthwise dimensions is substantially constant along said upper and lower perimetrical
regions, respectively.
16. The cushion as in claim 11, wherein the upper perimeter region is between
about 15% to about 30% of the entire perimeter of the cushion, the lower perimeter region
is between about 50% to about 70% 0fthe entire perimeter of the cushion, and the
transition regions are about 10% to about 30% of the entire perimeter of the cushion.

17. The cusl~on as ~ claim 16, wherein the gusset portion has substantially
zero widthwise dimension at said upper perimetrical region thereof.
18. The cushion as in claim 16, wherein said widthwise transitions are
carwilLnear.
19. The cushion as in claim 16, wherein the widthwise transitions are linear.
20. The cushion according to any one of claims 1-19, wherein the face
contacting portion and the gusset portion have a projected surface area in the range of 80-
140 em2.
21. The cushion accord~g to claim 20, ~vherein the face contacting portion and
the gusset portion have a projected surface area of about 130era2.
22. A respiratory face mask comprising a mask frame having an inlet for
supplying a breathable gas, and a cushion as in any one of claims 1-21 attached to the
mask frame.
23. The respiratory face mask according to claim 22, wherein the cushiort is
provided in at least four sizes having dJa-~ensions that are proportional to one another.
