20. A forehead support assembly for a respiratory mask, comprising:
-
a forehead support comprising a pair of apertures, the pair of apertures being provided on opposites sides of a centerline of the forehead support, each aperture extending through the forehead support from a first side to a second side opposite the first side and configured to face a patient'"'"'s forehead; and a forehead pad assembly repeatably attachable to and detachable from the forehead support, the forehead pad assembly comprising a pair of forehead pads, the forehead pad assembly being formed of flexible material, each forehead pad comprising a curved base portion having a first side configured to face the forehead support when the forehead pad assembly is connected to the forehead support and a second side configured to engage the patient'"'"'s forehead; a support post extending from the first side of the base portion, the support post having a proximal end adjacent the first side of the base portion and a distal end opposite the proximal end, the support post comprising a head at the distal end, a first region between the head and the proximal end and a second region between the head and the proximal end, the first region being a necked down region having a cross-sectional area smaller than a cross-sectional area of a base of the head such that a lip is formed between the base of the head and the necked down region, the second region extending to a first distance from a longitudinal axis of the support post, the base of the head having a cross-sectional area that is larger than a cross-sectional area of the apertures of the forehead support and extending from the longitudinal axis of the support post to a second distance that is less than the first distance; and a hollowed out region extending a predetermined distance through the base portion; the forehead pad assembly further comprising a connector that connects the base portions, wherein the forehead pad assembly is attachable to the forehead support by applying an axial force on each base portion in an axial direction of each support post to insert each support post through a respective aperture in the forehead support to distort the head and the lip until the lip reaches an end of the aperture and returns to its undistorted shape and engages a surface of the forehead support surrounding the aperture, and the forehead pad assembly is detachable from the forehead support by applying a pulling force to each base portion in a direction opposite to the pressure applied for insertion to distort the lip and the head to disengage the lip from the surface of the forehead support. - View Dependent Claims (21, 22, 23, 24, 25, 26)

27. A one-piece integrally molded forehead pad comprising:
-
a substantially rectangular base portion having a first side and an opposing second side, the first side being concavely curved and having a raised surface pattern, the second side being convexly curved; a support post projecting from the second side of the base portion at an oblique angle defined between a tangent to the second side of the base portion at a point of contact between the support post and the base portion, the support post comprising at least one undercut adapted to increase a flexibility of the support post; a hollowed out region extending through the base portion and partly into the support post, the hollowed out region configured to make the support post axially compressible; a head adapted to connect the forehead pad to a forehead support of a respiratory mask, a top surface of the head having a substantially rectangular first portion that merges with a substantially triangular second portion, the head being tapered from a bottom portion to the top surface and extending to a first distance from a longitudinal axis of the support post; and a necked down region located between the support post and the head, a cross-sectional area of the necked down region being smaller than a cross-sectional area of a top portion of the support post and smaller than a cross-sectional area of the bottom portion of the head so as to form a first lip at a base of the head and a second lip at the top portion of the support post, wherein the support post includes a tapered portion such that a region at the base portion has a larger cross-sectional area than the head, and wherein a portion of the support post extends to a second distance from the longitudinal axis of the support post, the first distance being less than the second distance. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
