Abstract

The invention relates to a bearing for a support rod ( 13 a, 13 b ) of a headrest ( 11 ) for vehicle seats, having at least one frame ( 16 ) forming an opening ( 17 ) through which the support rod ( 13 a, 13 b ) can pass, wherein the frame ( 16 ) at least partially engages around the opening ( 17 ), wherein the bearing ( 10 ) has at least one contact region ( 18 ) for contacting the outer surface ( 27 ) of the support rod ( 13 a, 13 b ) that is connected by a connector to a support region ( 28 ) that is part of the frame ( 16 ).

First claim

The invention claimed is:

1. In combination with a motor-vehicle headrest, a support spaced from the headrest, and a rod extending along an axis between the headrest and the support, a bearing in the headrest or in the support, the bearing comprising:
a frame forming an opening centered on the axis and through which the rod passes axially, the frame completely surrounding the opening;
angularly extending arms angularly equispaced about the axis in the frame about the opening relative to the axis and each having an inner end fixed to the support and, spaced angularly therefrom relative to the axis, an outer end that is radially deflectable relative to the axis; and
a spring annularly surrounding the opening and bearing radially inwardly on at least the outer ends of the arms to urge the arms radially inward into engagement with the rod.

2. The combination according to claim 1 , wherein each arm is elastically deformable.

3. The combination according to claim 1 , wherein each arm at least partially forms a concavity open toward the opening.

4. The combination according to claim 1 , wherein the spring is a circular spring.

5. The combination defined in claim 1 , wherein the bearing has a maximum dimension measured parallel to the axis that is substantially smaller than its maximum dimension measured perpendicular to the axis.

6. The combination defined in claim 5 , wherein the arms are all identical and are unitarily formed with the frame of an elastically deformable material.

7. The combination defined in claim 1 , wherein the spring engages each arm from the respective inner end to the respective outer end.
