Forehead support for facial mask
First Claim
1. A forehead support for a respiratory mask, comprising:
- a bridge structured and configured to be positioned above the mask adjacent a user'"'"'s forehead, the bridge including upper and lower pad engaging surfaces and at least one pad retainer between the pad engaging surfaces; and
a forehead pad comprising;
an outer wall having a first side configured to engage a user'"'"'s forehead and a second side having engaged surfaces configured to rest against the pad engaging surfaces of the bridge;
at least one retaining wall provided between the first side and the second side; and
at least one retained portion configured to be retained by the at least one pad retainer on the bridge,wherein a space is defined between the first side and the second side, the space comprises a substantially constant cross sectional profile, and the outer wall, the at least one retaining wall, and the engaged surfaces are formed of a deformable elastomeric material, wherein deformation of the pad occurs by deflection of at least the outer wall and the at least one retaining wall.

Abstract
A pad for a forehead support includes an outer wall having a first side configured to engage a user'"'"'s forehead and a second side having engaged surfaces configured to rest against engaging surfaces of the forehead support; at least one retaining wall provided between the first side and the second side; and at least one retained portion configured to be retained by a retainer formed on the forehead support, wherein a space is defined between the outer wall and the engaged surfaces. The space has a substantially constant cross sectional profile, and the outer wall, the at least one retaining wall, and the engaged surfaces are formed of a deformable elastomeric material. Deformation of the pad occurs by deflection of at least the outer wall and the at least one retaining wall.

4. A respiratory mask, comprising:
-
a face contact portion configured to engage the patient'"'"'s face; a forehead support connected to the face contact portion, the forehead support including a bridge structured and configured to be positioned above the mask adjacent the patient'"'"'s forehead, the bridge including upper and lower pad engaging surfaces and at least one pad retainer between the pad engaging surfaces; and a forehead pad comprising; an outer wall having a first side configured to engage a user'"'"'s forehead and a second side having engaged surfaces configured to rest against the pad engaging surfaces of the bridge; at least one retaining wall provided between the first side and the second side; and at least one retained portion configured to be retained by the at least one pad retainer on the bridge, wherein a space is defined between the first side and the second side, the space comprises a substantially constant cross sectional profile, and the outer wall, the at least one retaining wall, and the engaged surfaces are formed of a deformable elastomeric material, wherein deformation of the pad occurs by deflection of at least the outer wall and the at least one retaining wall. - View Dependent Claims (5, 6, 7, 8, 9)

10. A forehead support for a respiratory mask, comprising:
-
a connection structure configured to be positioned above the mask, the connection structure providing a connection point for connecting the forehead support to the mask; a bridge configured to be positioned above the mask adjacent a user'"'"'s forehead, the bridge having a horizontal length; an arm extending along a plane that intersects the connection structure, the arm connecting the bridge to the connection structure, the arm being configured so that movement of the arm relative to the connection structure along the plane translates to linear movement of the bridge that is toward and away from the connection structure and is in a direction substantially parallel to the plane; and a forehead pad mounted on the bridge and extending substantially the horizontal length of the bridge to provide multi-point contact with a wearer'"'"'s forehead, the forehead pad having a central portion and lateral ends, wherein the forehead pad is arranged to be between a wearer'"'"'s forehead and the bridge when the forehead support engages the wearer'"'"'s forehead, and wherein the position of the connection structure is fixed relative to the mask so that when the bridge moves linearly toward and away from the connection structure, the bridge moves linearly toward and away from a front a front plane aligned with a front side of the mask, and wherein the bridge comprises a central portion and two lateral portions, the lateral portions being angled relative to the central portion so that lateral edges furthest from the central portion are rearward of the central portion. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
