Abstract

A breathing mask arrangement includes a frame portion, a sealing lip provided to the frame portion and adapted to form a seal with a user'"'"'s face, a forehead support provided to the frame portion, and a forehead cushion removably secured to the forehead support. The forehead cushion includes a contact portion having a contact surface adapted to contact a user'"'"'s forehead and a connecting structure structured to couple the forehead cushion to the forehead support and allow pivoting and/or tilting movement of the contact portion relative to the forehead support. The connecting structure includes a support foot adapted to be received within a respective opening provided in the forehead support.

Claims

1. A breathing mask arrangement, comprising:

a frame portion;

a sealing lip provided to the frame portion and adapted to form a seal with a user'"'"'s face;

a forehead support provided to the frame portion; and

a forehead cushion removably secured to the forehead support,

the forehead cushion including a contact portion having a contact surface adapted to contact a user'"'"'s forehead and a connecting structure structured to couple the forehead cushion to the forehead support and allow pivoting and/or tilting movement of the contact portion relative to the forehead support,

the connecting structure including a support foot adapted to be received within a respective opening provided in the forehead support.

2. A breathing mask arrangement according to claim 1, wherein the forehead support includes arm elements adapted to support the forehead cushion, each arm element including an end portion that provides an opening through which a portion of an upper headband arrangement is structured to pass.

3. A breathing mask arrangement according to claim 2, wherein the forehead support is T-shaped.

4. A breathing mask arrangement according to claim 3, wherein the forehead cushion is formed of an elastomeric material.

5. A breathing mask arrangement according to claim 4, wherein the contact portion includes a pad like configuration.

6. A breathing mask arrangement according to claim 5, wherein the contact surface of the contact portion is concavely inwardly curved.

7. A breathing mask arrangement according to claim 6, wherein the forehead cushion includes two forehead cushions.

8. A breathing mask arrangement according to claim 7, wherein the two forehead cushions are connected with each other by a flexible bridge portion.

9. A breathing mask arrangement according to claim 8, wherein the two forehead cushions are formed integrally with one another.

10. A breathing mask arrangement according to claim 9, wherein each forehead cushion includes at least one hole or passage through the contact surface.

11. A breathing mask arrangement according to claim 10, wherein at least a surface portion of the forehead cushion adapted to contact with the skin of the mask user has a velvety matt surface.

12. A breathing mask arrangement, comprising:

a frame portion;

a sealing lip provided to the frame portion and adapted to form a seal with a user'"'"'s face;

a forehead support provided to the frame portion; and

a forehead cushion removably secured to the forehead support, the forehead cushion including;

a contact portion having a contact side providing a contact surface and a rear side, wherein the contact portion is constructed to pivot and/or tilt relative to the forehead support in use; and

a support foot provided to the rear side of the contact portion.

15. A breathing mask arrangement according to claim 12, wherein the forehead support includes arm elements adapted to support the forehead cushion, each arm element including an end portion that provides an opening through which a portion of an upper headband arrangement is structured to pass.

16. A breathing mask arrangement according to claim 15, wherein the forehead support is T-shaped.
