Abstract

An adjusting device ( 1 ) for a motor vehicle interior component includes a housing ( 3 ) in which a rotational element ( 2 ) is provided in a rotatable manner about a rotation axis ( 100 ). A first locking element ( 21 ) is rotationally fixed to the rotational element ( 2 ), and a second locking element ( 22 ) is provided on the housing ( 3 ). The locking elements are reversibly movable relative to each other from a locked situation, in which the locking elements ( 21, 22 ) interact with each other in a positively and/or non-positively engaged manner, into an adjustment situation, in which said positive and/or non-positive engagement is released. The adjusting device has an adapter plate ( 23 ) which is provided in a rotatable manner relative to the rotational element ( 2 ) and the housing ( 3 ) and at least temporarily drives a locking element ( 21, 22 ).

First claim

The invention claimed is:

1. An adjusting device for a motor vehicle interior component, the adjusting device comprising:
a housing in which a rotational element is provided in a rotatable manner about a rotation axis;
a first locking element rotationally fixed to the rotational element;
a second locking element is provided on the housing, said locking elements being reversibly movable relative to each other from a locked situation, in which the locking elements interact with each other in a positively engaged manner, into an adjustment situation, in which said positive engagement is released, second locking element being displaced between said locked situation and said adjustment situation by said second locking element being elastically deformed between one end fixed to said housing and other end engaging with said first locking element;
an adapter plate which is provided in a rotatable manner relative to the rotational element and the housing and at least temporarily drives a locking element;
an actuating means provided on the adapter plate;
an unlocking element on the second locking element, said unlocking element interacting with the actuating means.

2. The adjusting device as claimed in claim 1 , wherein the second locking element is provided as a web shaped sheet metal part formed from spring steel.

3. The adjusting device as claimed in claim 2 , further comprising a spring element pretensioned in a direction of the adapter plate, said spring element being incorporated into said web shaped sheet metal part.

4. The adjusting device as claimed in claim 1 , wherein the second locking element has a fastening means for fastening said locking element to the housing.

5. The adjusting device as claimed in claim 4 , wherein the fastening means is a snap fastener.

6. The adjusting device as claimed in claim 4 , wherein a positive engagement means is provided on the second locking element at a distance from the fastening means and interacts in a positively engaged manner with the first locking element in the locked situation.

7. The adjusting device as claimed in claim 6 , wherein the positive engagement means is incorporated into the material of the second locking element by deformation, primary forming or cutting.

8. The adjusting device as claimed in claim 4 , wherein:
the unlocking element is provided on the second locking element at a distance from the fastening means.

9. The adjusting device as claimed in claim 8 , wherein the unlocking element is provided as at least one of a protuberance and an indentation in the material of the second locking element.

10. The adjusting device as claimed in claim 9 , wherein the second locking means moves at least in sections along a displacement direction from the locked situation into the adjustment situation.

11. The adjusting device as claimed in claim 10 , wherein the protuberance has an oblique surface relative to the displacement direction.

12. The adjusting device as claimed in claim 1 , wherein said adjusting device is part of a vehicle seat.

13. The adjusting device as claimed in claim 5 , wherein a positive engagement means is provided on the second locking element at a distance from the fastening means and interacts in a positively engaged manner with the first locking element in the locked situation.

14. An adjusting device for a motor vehicle interior component, the adjusting device comprising:
a housing;
a rotational element arranged in said housing and rotatable with respect to said housing about a rotation axis;
a first locking element rotationally fixed to said rotational element;
a second locking element having a first end fixed on said housing, said second locking element have a diametrically opposite second end being movable relative to said first locking element along an axial direction of said rotation axis between a locked position rotationally fixing said locking elements to each other, and to an adjustment position in which said locking elements are movable relative to each other about said rotation axis, second locking element being displaced between said locked position and said adjustment position by said second locking element being elastically deformed between said first and second ends;
an adapter plate rotatably mounted on said housing and said rotational element, said adapter plate being adapted to move one of said locking elements when rotated.

15. The adjusting device as claimed in claim 14 , wherein:
said adapter plate moves said second end of said second locking element along said axial direction relative to said housing when said adapter plate is rotated relative to said housing.

16. The adjusting device as claimed in claim 14 , further comprising:
a spring incorporated into said second locking element between said first and second end and biasing said second end of said second locking element into said locked position.

17. The adjusting device as claimed in claim 14 , further comprising:
a fastener as part of said first end of said second locking element and fastening said second locking element to said housing;
an actuator mounted on said adapter plate;
an unlocking element mounted on said second locking element at a position spaced from said fastener.

18. The adjusting device as claimed in claim 17 , wherein:
said unlocking element is adapted to interact with said actuator, said unlocking element being one of a protuberance and an indentation in material of said second locking element.

19. The adjusting device as claimed in claim 14 , wherein:
said second locking element extends diametrically across said rotational element.

20. The adjusting device as claimed in claim 14 , wherein:
said second end of said second locking element bends with respect to said first end of said second locking element to move said second end between said locked position and said adjustment position.
