## Abstract

Disclosed is a flap bearing arrangement (10), having a bearing mount (20) with two side parts (24) connected by means of a tube section (22), between which is arranged an O-ring (30) which surrounds the tube section (22). Also disclosed is a flap bearing arrangement (100) for an intake device (200) having a flap shaft (100).

## Claims

### Claim 1

A flap bearing arrangement, comprising:
a bearing mount having two side parts, the two side parts spaced apart from each other;
a tube section extending between and connecting the two side parts, a direction of extension of the tube section defining an axial direction;
an O-ring circumferentially surrounding the tube section, the O-ring arranged between the two side parts.

### Claim 2 (depends on 1)

The flap bearing arrangement according claim 1, wherein
the two side parts each have a substantially rectangular cross-section perpendicular to the tube section extending between and connecting the two side parts.

### Claim 3 (depends on 2)

The flap bearing arrangement according to claim 2, wherein
the two side parts each have a radially outer circumference, where radial relative to the tube section connecting the two side parts;
wherein the O-ring projects radially only sectionally beyond the outer circumference of the two side parts.

### Claim 4 (depends on 3)

The flap bearing arrangement according to claim 3, wherein
the O-ring projects radially outwardly beyond the outer circumference of the two side parts by no more than 50% of an outer diameter of the O-ring.

### Claim 5 (depends on 1)

The flap bearing arrangement according to claim 1, wherein
a cylinder support is arranged on an outer side of each of the two side parts;
wherein the cylinder support projects outward axially, an axial direction relative to the tube section extending axially between and connecting the two side parts.

### Claim 6 (depends on 1)

The flap bearing arrangement according to claim 1, wherein
the bearing mount is formed from polyphenylene sulfide.

### Claim 7 (depends on 1)

The flap bearing arrangement according to claim 1, wherein
the O-ring is an elastomer.

### Claim 8
