Abstract

A bearing arrangement ( 4 ), for a rear seat arrangement of a vehicle, includes a bearing pin ( 5.2 ) which forms a rotational axis and a rotary bearing ( 5.3 ) which can be pushed onto the bearing pin ( 5.2 ). The bearing pin ( 5.2 ) and the rotary bearing ( 5.3 ) each have a mutually corresponding structure which secures the bearing pin ( 5.2 ) and the rotary bearing ( 5.3 ) against axial and radial movements relative to each other in a use position. The bearing pin ( 5.2 ) can be guided through openings ( 01, 02 ) of the rotary bearing ( 5.3 ) during assembly. The use position, which is secured against axial and radial movements, can be subsequently adjusted by pivoting the bearing pin ( 5.2 ) and/or the rotary bearing ( 5.3 ). A method for assembling the bearing arrangement ( 4 ) is also provided.

First claim

The invention claimed is:

1. A bearing arrangement for a rear seat arrangement of a vehicle, the bearing arrangement comprising:
a bearing pin forming a rotational axis; and
a rotary bearing which is able to be pushed onto the bearing pin, wherein the bearing pin and the rotary bearing in each case have a mutually corresponding structure which secures the bearing pin and the rotary bearing against axial and radial displacements relative to one another in a position of use, the structure of the bearing pin comprising at least two grooves which are spaced apart from one another and entirely surround an outer surface of the bearing pin, the structure of the rotary bearing comprising at least two wall regions which are arranged at the same distance from one another as the grooves, the wall regions in each case comprising an opening with a sliding surface entirely surrounding the opening in each case, wherein the bearing pin is guidable through openings of the rotary bearing during assembly, and the position of use which is secured against axial and radial displacements is subsequently adjustable by pivoting the bearing pin and/or the rotary bearing, the openings being arranged eccentrically to a rotational axis of the bearing pin which is located in the position of use.

2. The bearing arrangement as claimed in claim 1 , wherein the bearing pin is guided through the openings, wherein the sliding surfaces, surrounding the openings in the position of use of the rotary bearing, are rotatably arranged in the grooves.

3. The bearing arrangement as claimed in claim 1 , wherein the openings have an oval cross section.

4. The bearing arrangement as claimed in claim 3 , wherein the openings are rotated relative to one another by 180°, such that segments of the openings, with the smallest diameters of the respective oval, face in opposing directions.

5. The bearing arrangement as claimed in claim 4 , wherein the diameter of the segments of the openings, with the smallest diameters of the respective oval, corresponds to a second diameter of the bearing pins in the region of the grooves.

6. The bearing arrangement as claimed in claim 4 , wherein a diameter of segments of the openings, with the greatest diameters of the respective oval, corresponds at least to a first diameter of the bearing pins outside the regions of the grooves.

7. A vehicle rear seat arrangement bearing arrangement comprising:
a bearing pin forming a rotational axis and having a bearing pin outer contour;
a rotary bearing defining openings receiving the bearing pin, the openings having an openings contour, the bearing pin outer contour and the rotary bearing openings contour having corresponding shapes to define mutually corresponding structures wherein the mutually corresponding structures define pushing path guideway for the rotary bearing to be pushed onto a bearing pin in an assembly relative rotational extent which is different from a use relative rotational extent and to form a rotational axis of the bearing arrangement and to define a securing connection, securing the bearing pin and rotary bearing against a relative axial and a radial displacement in the use relative rotational extent, the bearing pin outer contour comprising grooves which are spaced apart from one another and which entirely surround an outer surface of the bearing pin, the rotary bearing comprising two wall regions arranged at the same distance from one another as the grooves, the wall regions each defining one of the openings, the openings having an oval cross section.

8. The bearing arrangement as claimed in claim 7 , wherein:
the bearing pin is guided through pushing path guideway; and
sliding surfaces are rotatably arranged in the grooves and surround the openings in the use relative rotational extent.

9. The bearing arrangement as claimed in claim 7 , wherein the openings are eccentric to the rotational axis of the bearing pin.

10. The bearing arrangement as claimed in claim 7 , wherein the openings are rotationally offset 180° relative to one another whereby segments of the openings, with a smallest dimension of the respective oval, face in opposing directions.

11. The bearing arrangement as claimed in claim 10 , wherein the smallest dimensions of the respective oval corresponds to a dimension of the bearing pins in a region of the grooves.

12. The bearing arrangement as claimed in claim 10 , wherein segments of the openings with a greatest dimension of the respective oval correspond at least to a first dimension of the bearing pins outside of a region of the grooves.

13. A bearing arrangement for a rear seat arrangement of a vehicle, the bearing arrangement comprising:
a bearing pin forming a rotational axis; and
a rotary bearing which is able to be pushed onto the bearing pin, wherein the bearing pin and the rotary bearing in each case have a mutually corresponding structure which secures the bearing pin and the rotary bearing against axial and radial displacements relative to one another in a position of use, the structure of the bearing pin comprising at least two grooves which are spaced apart from one another and entirely surround an outer surface of the bearing pin, the structure of the rotary bearing comprising at least two wall regions which are arranged at the same distance from one another as the grooves, the wall regions in each case comprising an opening with a sliding surface entirely surrounding the opening in each case, wherein the bearing pin is guidable through openings of the rotary bearing during assembly, and the position of use which is secured against axial and radial displacements is subsequently adjustable by pivoting the bearing pin and/or the rotary bearing, the openings having an oval cross section.

14. The bearing arrangement as claimed in claim 13 , wherein the openings are rotated relative to one another by 180°, such that segments of the openings, with the smallest diameters of the respective oval, face in opposing directions.

15. The bearing arrangement as claimed in claim 14 , wherein the diameter of the segments of the openings, with the smallest diameters of the respective oval, corresponds to a second diameter of the bearing pins in the region of the grooves.

16. The bearing arrangement as claimed in claim 14 , wherein a diameter of segments of the openings, with the greatest diameters of the respective oval, corresponds at least to a first diameter of the bearing pins outside the regions of the grooves.
