## Abstract

The invention relates to a respiratory mask with an interface for the connection of at least two components, wherein the interface is round or oval and has a maximum diameter, and the components each make available at least one subregion of the interface. The component has a grip part which extends radially outward from the subregion and which is configured as a pressing surface or gripping means for fingers or the hand of an operator, wherein the component has two grip parts, wherein the subregions are in form-fit engagement with each other in an assembled state and are movable about a rotation axis (DA), for which purpose the grip part is rotatable to different rotation positions relative to the two grip parts.

## Claims

### Claim 1

A respiratory mask, wherein the mask comprises an interface for connecting of at least two components, wherein the interface is round and has a diameter, the at least two components each providing at least one subregion of the interface, wherein a first one of the two components has a grip part which extends radially outward from a first one of the subregions and is configured as a pressing surface or gripping element for fingers or a hand of an operator, a second one of the two components has two grip parts which extend radially outward from a second one of the subregions and are configured as a pressing surface or gripping elements for fingers or a hand of the operator, and wherein the first and second subregions are in form-fit engagement with each other in an assembled state and are movable about a rotation axis which is perpendicular to the first and second subregions, for which purpose the grip part of the first one of the two components is rotatable to different rotation positions relative to the two grip parts of the second one of the two components.

### Claim 2 (depends on 1)

The mask of claim 1, wherein the grip part of the first component and the grip parts of the second component are dimensioned such that fingers of an operator find sufficient space on them.

### Claim 3 (depends on 1)

The mask of claim 1, wherein the grip part of the first component is configured as part of a forehead support and is formed integrally with the forehead support, the forehead support additionally comprising contact locations for a harness.

### Claim 4 (depends on 1)

The mask of claim 1, wherein the two grip parts of the second component are configured as part of a mask body and are formed integrally with the mask body, the grip parts additionally comprising contact locations for a harness.

### Claim 5 (depends on 3)

The mask of claim 3, wherein the two grip parts of the second component are configured as part of a mask body and are formed integrally with the mask body, the grip parts additionally comprising contact locations for a harness.

### Claim 6 (depends on 1)

The mask of claim 1, wherein surfaces of the grip part of the first component and the grip parts of the second component are provided with friction-enhancing elements to improve haptics thereof.

### Claim 7 (depends on 6)

The mask of claim 6, wherein the friction-enhancing elements comprise knobs.

### Claim 8 (depends on 6)

The mask of claim 6, wherein the friction-enhancing elements comprise ribs.

### Claim 9 (depends on 1)

The mask of claim 1, wherein the interface serves for connecting the first and second components and a third component, the three components being a mask body, a hose connector and a forehead support.

### Claim 10 (depends on 9)

The mask of claim 9, wherein spacer elements are arranged in an interface between the mask body as the first component and the forehead support as the second component.

### Claim 11 (depends on 1)

The mask of claim 1, wherein the grip part of the first component is longer than the diameter of the interface.

### Claim 12 (depends on 11)

The mask of claim 11, wherein the grip parts of the second component are each 50%-200% of the diameter of the interface.

### Claim 13 (depends on 1)

The mask of claim 1, wherein the grip parts of the second component are each 50%-200% of the diameter of the interface.

### Claim 14 (depends on 1)

The mask of claim 1, wherein the two grip parts of the second component are arranged symmetrically opposite each other on the second component.

### Claim 15 (depends on 1)

The mask of claim 1, wherein insertion bevels are present in a region of the interface.

### Claim 16 (depends on 15)

The mask of claim 15, wherein locking elements are present in the first and second subregions and the insertion bevels and the locking elements are configured and arranged such that operating forces needed to release a lock are higher than operating forces needed to close the lock.

### Claim 17 (depends on 1)

The mask of claim 1, wherein in a region of the interface, at least two symmetrically arranged locking elements are present in the first and second subregions.

### Claim 18 (depends on 1)

The mask of claim 1, wherein spacer elements are arranged in the interface between a mask body as the second component and a forehead support as the first component.

### Claim 19 (depends on 1)

The mask of claim 1, wherein the first and second components comprise at least one pointer and at least one symbol, the at least one pointer being capable of being aligned with the at least one symbol by rotation of the grip parts of the first and second components, the at least one symbol being positionally fixed and the at least one pointer being configured to be rotatable relative to the at least one symbol.

### Claim 20

A respiratory mask, wherein the mask comprises an interface for connecting of at least two components, wherein the interface is oval and has a maximum diameter, the at least two components each providing at least one subregion of the interface, wherein a first one of the two components has a grip part which extends radially outward from a first one of the subregions and is configured as a pressing surface or gripping element for fingers or a hand of an operator, a second one of the two components has two grip parts which extend radially outward from a second one of the subregions and are configured as a pressing surface or gripping elements for fingers or a hand of the operator, and wherein the first and second subregions are in form-fit engagement with each other in an assembled state and are movable about a rotation axis which is perpendicular to the first and second subregions, for which purpose the grip part of the first one of the two components is rotatable to different rotation positions relative to the two grip parts of the second one of the two components.
