Abstract

A sliding sleeve (6, 60) for fixing in a securing support (5, 50). The sliding sleeve (6, 60) includes a sleeve body (6.2, 60.2) with a coupling section (6.3, 60.3) with at least one flexible coupling face (6.4, 60.4) for bearing against the securing body (5, 50).

First claim

What is claimed is:

1 . A sliding sleeve for fixing in a securing body, the sliding sleeve comprising:
a sleeve body with a coupling section with at least one flexible coupling face for bearing against the securing support, wherein the at least one flexible coupling face comprises at least two flexible coupling faces configured to be arranged in a consecutive manner in a longitudinal direction, wherein an outer surface of each of the flexible coupling faces has a convex shape.

2 . A sliding sleeve according to claim 1 , wherein the outer surface of each of the flexible coupling faces is dome-shaped.

3 . A sliding sleeve according to claim 1 , wherein the outer surface of each of the flexible coupling faces is half-dome-shaped.

4 . A sliding sleeve according to claim 1 , wherein the outer surface of each of the flexible coupling faces is convex in a non-installed state, so that in an installed state the convex outer surface is compressed and is changed into a stressed state.

5 . A sliding sleeve according to claim 1 , wherein the sleeve body comprises at least one longitudinal edge wherein the at least two flexible coupling faces are alternately arranged at least 90° or 180° to each other along the at least one longitudinal edge.

6 . A sliding sleeve according to claim 5 , wherein the sliding sleeve is at least one of square, oval, ring-shaped or rectangular in cross-section and comprises outer sleeve sides next to one another wherein the at least two flexible coupling faces are arranged on outer sleeve sides arranged next to one another.

7 . A sliding sleeve according to claim 5 , wherein the sliding sleeve is at least one of square, oval, ring-shaped or rectangular in cross-section and comprises outer sleeve sides opposite to one another wherein the at least two flexible coupling faces are arranged on outer sleeve sides arranged opposite to one another.

8 . A sliding sleeve according to claim 1 , characterized in that at least one of the flexible coupling faces additionally comprises, in the coupling section, a wall portion with a fully enclosed cavity within the wall portion, wherein the least one fully enclosed cavity is covered to an outside by the bevelled outer surface.

9 . A sliding sleeve according to claim 8 , characterized in that the cavity is of circumferential configuration.

10 . A sliding sleeve according to claim 8 , wherein the cavity extends in a longitudinal direction of the sleeve body.

11 . A sliding sleeve according to claim 9 , wherein a length of the cavity in the longitudinal direction is greater than the depth of the cavity in the wall portion.

12 . A sliding sleeve for fixing in a securing body, the sliding sleeve comprising:
a sleeve body with a coupling section with at least one flexible coupling face for bearing against the securing support, wherein the sleeve body has a cross-section with a circular sector and at least one corner, so that the sleeve body has a longitudinal edge, wherein the flexible coupling face comprises at least two flexible coupling faces arranged in a consecutive manner along the edge and alternating between one side of the edge and the other side.

13 . A sliding sleeve according to claim 12 , wherein an outer surface of each of the flexible coupling faces has a convex shape.

14 . A sliding sleeve according to claim 12 , wherein the outer surface of each of the flexible coupling faces is dome-shaped.

15 . A sliding sleeve according to claim 12 , wherein the outer surface of each of the flexible coupling faces is half-dome-shaped.

16 . A sliding sleeve according to claim 12 , wherein the outer surface of each of the flexible coupling faces is convex in a non-installed state, so that in an installed state the convex outer surface is compressed and is changed into a stressed state.

17 . A sliding sleeve according to claim 12 , wherein at least one of the flexible coupling faces comprises, in the coupling section, a wall portion having an opening which is only accessible from one side of the edge, wherein the opening is covered to an outside by a convex outer surface of at least one of the flexible coupling faces.

18 . A headrest arrangement, in particular for a seat, comprising:
two headrest rods which are spaced apart from one another in parallel; a headrest body which is fastened to the headrest rods; two securing supports which are arrangeable and fixable in a frame of a backrest of the seat; and sliding sleeves, each of the sliding sleeves being arranged in a respective one of the securing supports and each of the sliding sleeves comprising a sleeve body with a coupling section with at least one flexible coupling face for bearing against the securing support, wherein the at least one flexible coupling face comprises at least two flexible coupling faces configured to be at least one arranged above and arranged next to one another in the longitudinal direction, wherein an outer surface of each of the flexible coupling faces has a convex shape.

19 . A headrest arrangement according to claim 18 , wherein the outer surface of each of the flexible coupling faces is dome-shaped.

20 . A headrest arrangement according to claim 18 , wherein the outer surface of each of the flexible coupling faces is half-dome-shaped.

21 . A headrest arrangement according to claim 18 , wherein the outer surface of each of the flexible coupling faces is convex in a non-installed state, so that in an installed state the convex outer surface is compressed and is changed into a stressed state.
