Abstract

A locking unit ( 10 ) for a vehicle seat ( 1 ) includes a housing with at least on side plate ( 16 ) and/or a cover plate ( 18 ), and at least one bearing bolt ( 51, 52 ) having a bearing axis ( 56 ). The at least one bearing bolt ( 51, 52 ), in an axial direction, is penetrated by a through opening ( 55 ) having a through axis ( 53 ). The through axis ( 53 ) of the through opening ( 55 ) extends offset to the bearing axis ( 56 ) of the bearing bolt ( 51, 52 ).

First claim

The invention claimed is:

1. A locking unit for a vehicle seat, the locking unit comprising:
a housing comprising at least one plate; and
at least one bearing bolt having a bearing axis which, in the axial direction, is penetrated by a through-opening having a through-axis, wherein the through-axis of the through-opening extends offset to the bearing axis of the bearing bolt, wherein the bearing bolt is inserted into at least a bearing bore of the at least one plate, wherein the plate on the edge of the bearing bore has at least one press-fit region, material of the bearing bolt passing therein by means of compression.

2. The locking unit as claimed in claim 1 , wherein the through-axis extends parallel to the bearing axis.

3. The locking unit as claimed in claim 1 , wherein the bearing bolt, on a bearing bolt outside, has a contour which is at least approximately rotationally symmetrical to the bearing axis.

4. The locking unit as claimed in claim 1 , wherein the through-opening has a contour which is at least approximately rotationally symmetrical to the through-axis.

5. The locking unit as claimed in claim 4 , wherein the through-opening has a circular cylindrical contour.

6. The locking unit as claimed in claim 1 , wherein the at least one plate is comprised primarily of metal.

7. The locking unit as claimed in claim 1 , wherein the at least one plate on the edge of the bearing bore has a plurality of press-fit regions.

8. The locking unit as claimed in claim 7 , wherein each press-fit region has the maximum spacing from the respectively adjacent press-fit region.

9. The locking unit as claimed in claim 1 , wherein a plurality of press-fit regions are uniformly distributed along the edge of the bearing bore.

10. The locking unit as claimed in claim 1 , wherein the housing comprises a cover plate, the cover plate being comprised primarily of plastics material.

11. The locking unit as claimed in claim 1 , wherein the housing comprises a cover plate, the cover plate on the edge of a second bearing bore has at least one groove, a stud of the bearing bolt engaging therein.

12. A vehicle seat comprising at least one locking unit, the locking unit comprising:
a housing comprising at least one plate; and
at least one bearing bolt having a bearing axis which, in the axial direction, is penetrated by a through-opening having a through-axis, wherein the through-axis of the through-opening extends offset to the bearing axis of the bearing bolt, wherein the bearing bolt is inserted into at least a plate bearing bore, wherein the at least one plate is comprised primarily of metal, wherein the at least one plate comprises a press-fit region on an edge of the plate bearing bore such that the bearing bolt passing therein by means of compression.

13. A vehicle seat as claimed in claim 12 , wherein:
the through-axis extends parallel to the bearing axis; and
the bearing bolt has a bearing bolt outside with a contour which is at least approximately rotationally symmetrical to the bearing axis;

a through-opening
the through-opening has a contour which is at least approximately rotationally symmetrical to the through-axis.

14. A vehicle seat as claimed in claim 12 , wherein:
the at least one plate comprises at least another press-fit region on an edge of the plate bearing bore the side plate to provide a plurality of press-fit regions;
each press-fit region has a maximum spacing from an adjacent press-fit region;
each of the plurality of press-fit regions is uniformly distributed along the edge of the plate bearing bore.

15. A vehicle seat as claimed in claim 12 , wherein:
the housing comprises a cover plate;
the cover plate is comprised primarily of plastics material;
on an edge of a cover plate bearing bore the cover plate has at least one groove; and
a stud of the bearing bolt engages in the at least one groove.
