1. A control device to reduce a vibration movement (15) on a device (1) vibrating under spring force with at least two mobile parts (3, 4) vibrating in relation to each other, wherein the parts (3, 4) are connected together by means of mobile connecting arms (5, 6), at least one of the connecting ar
1. A control device to reduce a vibration movement (15) on a device (1) vibrating under spring force with at least two mobile parts (3, 4) vibrating in relation to each other, wherein the parts (3, 4) are connected together by means of mobile connecting arms (5, 6), at least one of the connecting arms (6) is connected at least indirectly with a first spring element end (16a) of at least one spring element (16) and between the parts (3, 4) is arranged at least one damping element (13), characterised in that at least one link track element (18), in or on which under a vibration movement (15) a guide element (24) connected with the first spring element end (16a) and in contact with the first connecting arm (6) is arranged mobile on a link track (19a-d), wherein a movement course of the guide element (24) can be modified by position-changeable curve elements (20, 21) to deviate at least in part from the curve of the link track (19a-19d). 2. The control device according to claim 1, characterised in that the curve elements (20, 21) are connected with the damping element (13) and can be positioned differently (28, 29) in dependency of the momentary size of a damping force of the damping element (13) which depends on a momentary vibration speed of the two mobile parts (3, 4) vibrating in relation to each other. 3. The control device according to claim 2, characterised in that the curve elements (20, 21) can swivel about a swivel axis (22, 23), wherein the curve elements (20, 21) have curve section tracks (20a, 21a) along which the guide element (24) can be guided deviating from the course of the link track (19a-d). 4. The control device according to claim 3, characterised in that the damping element (13) has at least one extendable piston rod (14), on the end (13a) of which are attached at least two rod elements (26, 27) that are connected with the at least two swivelable curve elements (20, 21), wherein the swivel position (28, 29) of the curve elements (20, 21) can be adjusted by extension and retraction of the piston rod (14). 5. The control device according to claim 3 or 4, characterised in that the curve elements (20, 21) are subject to resistance in their swivel movement (28, 29) from a swivel adjustment force. 6. The control device according to claim 5, characterised in that the changing damping force of the damping element (13) is less than, equal to or greater than the swivel adjustment force. 7. The control device according to claim 6, characterised in that the link track (19a-d) reflects at least part of a course of a force-travel vibration springing curve (44, 70-72, 75-77). 8. The control device according to claim 7, characterised in that the course of the vibration springing curve (44, 70-72, 75-77) has a first region (41) with a slight first gradient and for higher vibration speeds a second and third region (42, 43) arranged in the springing end position zones with a second and third gradient steeper than the first gradient. 9. The control device according to claim 8, characterised in that the second region (42) and the third region (43), on a vibration movement (15) in the direction (73, 78) of the springing end positions, have at least partly a shallower gradient (70, 75) than on the opposite vibration movement (74, 79). 10. The control device according to claim 7, characterised in that the course of the vibration springing curve (44, 50, 53) at low vibration speeds has the same gradient both in a first region (41) lying between the springing end position zones and in a second region (42) and third region (43) also lying in one of the springing end position zones. 11. The control device according to claim 1, characterised in that the spring element (16) in the region of the upper part (3) in relation to the other part (4) is arranged running almost horizontal and by the first end (16a) is connected with the guide element (24) and indirectly with the first end (6a) of the connecting arm (6) and by the second end (16b) with the top part (3). 12. The control device according to claim 1, characterised in that it is intended for a vehicle seat with a seat part on the top as a first part (3) and with a seat frame lower part underneath as the second part (4).
