Abstract

An actuating device ( 100 ) has a first part ( 5 a; 334; 434 ) and a second part ( 5 b; 310; 412 ) which can be pivoted about a first axis (A) relative to the first part ( 5 a ). A first segment ( 140 ) can be coupled to the first part. A second segment ( 150 ) can be rotated about the first axis (A) relative to the first segment ( 140 ) and can be connected to a locking device of a component ( 20 ) and/or to a locking device ( 350; 450 ) of another component ( 330; 430 ). Rotation of a deflecting element ( 120 ) moves a transfer element ( 130 ) such that the second segment ( 150 ) is not rotated about the first axis (A). Changing a distance between the first axis (A) and a second axis © allows the second segment ( 150 ) to be rotated about the first axis by the transfer element ( 130 ). A vehicle seat includes such an actuating device ( 100 ).

First claim

The invention claimed is:

1. An actuating device for connecting to a vehicle seat component, wherein the component has a first part and a second part which is pivotable about a first axis relative to the first part, the actuating device comprising:
a first segment which can be coupled kinematically to the first part;
a second segment which is rotatable about the first axis relative to the first segment and is connectable to a locking device of the component and/or to a locking device of a further component;
an actuating lever;
a deflecting element which is coupled to the actuating lever and has a deflecting surface which is curved about a second axis;
a flexible transmission element, wherein
a distance between the second axis and the first axis is changeable to a limited extent
a first region of the flexible transmission element is fastened to the first segment;
a second region of the flexible transmission element is fastened to the second segment;
the flexible transmission element runs over the deflecting element
upon the deflecting element rotating about the first axis, the flexible transmission element is moved over the deflecting element, is moved over the first segment and is moved over the second segment such that the second segment remains unrotated with respect to the first axis; and
upon the distance between the first axis and the second axis changing, the second segment is rotated about the first axis by the flexible transmission element.

2. The actuating device as claimed in claim 1 , wherein the actuating lever is coupled kinematically to the second part or is coupled to a third part which is connected rotatable about an axis of rotation to the second part, wherein the axis of rotation between the second part and the third part is aligned with the second axis in the unactuated state of the actuating device.

3. The actuating device as claimed in claim 1 , wherein the deflecting element is mounted on the actuating lever so as to be rotatable about the second axis.

4. The actuating device as claimed in claim 1 , wherein the actuating lever is mounted rotatably about a lever axis of rotation.

5. The actuating device as claimed in claim 4 , wherein the first axis of rotation, the lever axis of rotation and the second axis, as a deflecting axis, form corner points of an imaginary triangle, with inside angles that are changeable by actuation of the actuating lever.

6. The actuating device as claimed in claim 1 , wherein the deflecting element is mounted rotatably about the second axis on a coupling lever which is coupled to the actuating lever.

7. The actuating device as claimed in claim 6 , wherein the coupling lever has two ends, wherein a first end is coupled pivotably to the actuating lever and a second end has the deflecting element.

8. The actuating device as claimed in claim 1 , wherein the first segment and the second segment each have a surface which is curved about the first axis.

9. A vehicle seat with an actuating device comprising:
a vehicle seat component, wherein the component has a first part and a second part which is pivotable about a first axis relative to the first part;
a first segment which can be coupled kinematically to the first part;
a second segment which is rotatable about the first axis relative to the first segment and is connectable to a locking device of the component and/or to a locking device of a further component;
an actuating lever;
a deflecting element which is coupled to the actuating lever and has a deflecting surface which is curved about a second axis;
a flexible transmission element, wherein
a distance between the second axis and the first axis is changeable to a limited extent
a first region of the flexible transmission element is fastened to the first segment;
a second region of the flexible transmission element is fastened to the second segment;
the flexible transmission element runs over the deflecting element
upon the deflecting element rotating about the first axis, the flexible transmission element is moved over the deflecting element, is moved over the first segment and is moved over the second segment such that the second segment remains unrotated with respect to the first axis;
upon the distance between the first axis and the second axis changing, the second segment is rotated about the first axis by the flexible transmission element.

10. The vehicle seat as claimed in claim 9 , further comprising:
a seat substructure;
a back rest; and
a fitting system, wherein the back rest is connected to the seat substructure by the fitting system, and the fitting system, in an unlocked state, permits the back rest to pivot freely, and the actuating device actuates the fitting system.

11. The vehicle seat as claimed in claim 10 , wherein the fitting system comprises at least one fitting with a first fitting part associated with the vehicle seat component and a second fitting part, which first fitting part and second fitting part are lockable to each other and, in an unlocked state, are rotatable relative to each other about a back rest axis of rotation.

12. The vehicle seat as claimed in claim 11 , wherein the first segment is coupled kinematically to a fitting lower part of the first fitting part, which fitting lower part is fixedly connected to the first fitting part, and the second segment is connected to a locking device of a transmission element of the at least one fitting, wherein the transmission element is aligned with the back rest axis of rotation, for rotation therewith or is coupled thereto for carrying along therewith.

13. The vehicle seat as claimed in claim 9 , further comprising:
a seat rail arrangement; and
a seat part pivotable about the first axis relative to the seat rail arrangement, wherein:
the locking device of the further component locks the seat rail arrangement;
the actuating device unlocks the locking device of the further component;
the first segment is kinematically coupled to a rail profile of the seat rail arrangement and the actuating lever is kinematically coupled to the seat part.

14. The vehicle seat as claimed in claim 9 , further comprising:
a seat part;
a seat rail arrangement; and
height adjustment kinematics with a front link and a rear link configured to height adjust the seat part relative to the seat rail arrangement, wherein:
the locking device of the further component locks the seat rail arrangement; and
the actuating device unlocks locking device of the further component;
the first segment is kinematically coupled to a rail profile of the seat rail arrangement and the actuating lever is kinematically coupled to the seat part.
