Abstract

An application device for a breathing mask arrangement includes a base portion, a holding portion structured to support a mask and pivotally mounted to the base portion for pivotal movement about a first pivcit axis, a right arm element pivotally mounted to the base portion for pivotal movement about a second pivot axis, and a left arm element pivotally mounted to the base portion for pivotal movement about a third pivot axis. The right and left arm elements are each provided with a contact portion for bearing against a right and a left forehead zone respectively of a mask user. The holding portion, the right arm element, and left arm element can be pivoted with respect to the base portion about the respective first, second, and third pivot axes.

Claims

1-24. -24. (canceled)

25. A breathing mask, comprising:

a frame;

a sealing structure supported by the frame and adapted to form a seal with a user'"'"'s face;

a forehead support provided to the frame; and

a finger-operated adjusting wheel rotatable about an axis of rotation to adjust a position of the forehead support relative to the frame.

26. A breathing mask according to claim 25, wherein the axis of rotation is adapted to extend substantially perpendicular to a surface of the patient'"'"'s forehead.

27. A breathing mask according to claim 25, wherein the forehead support includes a left arm element and a right arm element.

28. A breathing mask according to claim 27, wherein the left and right arm elements include forehead pads.

29. A breathing mask according to claim 27, wherein the adjusting wheel is structured to simultaneously adjust a position of the left and right arm elements relative to the frame.

30. A breathing mask according to claim 25, wherein the adjusting wheel is adapted to be rotated by only one hand of the mask user.

31. A breathing mask according to claim 25, wherein the adjusting wheel is adapted to be rotated by way of the fingertips of the thumb and the index finger of the mask user.

32. A breathing mask according to claim 25, wherein the adjusting wheel is coupled to the forehead support by a drive mechanism.

33. A breathing mask according to claim 32, wherein the drive mechanism includes a screw-type drive mechanism.

34. A breathing mask according to claim 32, wherein the drive mechanism includes a spiral-type drive mechanism including a spiral structure provided to the adjusting wheel operatively engaged with an actuating member provided to the forehead support.

35. A breathing mask according to claim 32, wherein the drive mechanism is self-locking.

36. A breathing mask according to claim 25, wherein the adjusting wheel includes profiling along an outside peripheral region thereof.

37. A breathing mask according to claim 25, wherein the profiling includes a fluted or grooved structure.

38. A breathing mask according to claim 25, wherein the adjusting wheel includes a marking to indicate an adjusting effect achieved by rotating the adjusting wheel.

39. A breathing mask according to claim 25, wherein the forehead support is movable into a defined position by the adjusting wheel.

40. A breathing mask according to claim 25, wherein the forehead support includes arm elements that adapted to be maintained in a substantially horizontal position with respect to the patient'"'"'s forehead while the adjusting wheel is rotated about the axis of rotation.

44. A breathing mask according to claim 40, wherein the adjusting dial is coupled to the forehead support by a screw-type drive mechanism.

41. A breathing mask, comprising:

a frame;

a sealing structure supported by the frame and adapted to form a seal with a user'"'"'s face;

a forehead support provided to the frame; and

an adjusting dial to adjust a position of the forehead support relative to the frame, the adjustable dial rotatable about an axis of rotation adapted to extend substantially perpendicular to a surface of the patient'"'"'s forehead.

42. A breathing mask according to claim 41, wherein the adjusting dial is adapted to be rotated by only one hand of the mask user.

43. A breathing mask according to claim 41, wherein the forehead support includes arm elements that adapted to be maintained in a substantially horizontal position with respect to the patient'"'"'s forehead while the adjusting dial is rotated about the axis of rotation.
