Abstract

A device for manually and/or electromotively adjusting or securing a first vehicle part and a second vehicle part relative to each other is provided. The device comprising an adjustment part which has a joint for pivotable arrangement on the first vehicle part, wherein the adjustment part is to be arranged on the first vehicle part in such a manner that, when the vehicle parts are adjusted relative to each other, the adjustment part moves relative to the second vehicle part, a traction cable which is fastened at a first end and at a second end to the adjustment part, and a cable drum which is to be arranged on the second adjustment part, is rotatable about a longitudinal axis and on which the traction cable is arranged.

Claims

1. A device for manually or electromotively adjusting or securing a first vehicle part and a second vehicle part relative to each other, the device comprising:

an adjustment part which has a joint for pivotable arrangement on the first vehicle part, wherein the adjustment part is to be arranged on the first vehicle part in such a manner that, when the vehicle parts are adjusted relative to each other, the adjustment part moves relative to the second vehicle part;

a traction cable which is fastened at a first end and at a second end to the adjustment part;

a cable drum which is to be arranged on the second adjustment part, is rotatable about a longitudinal axis, and on which the traction cable is arranged in such a manner that, when the second vehicle part is adjusted relative to the first vehicle part, the traction cable is wound up with one portion onto the cable drum and is unwound with another portion from the cable drum, wherein the cable drum is accommodated in a cable drum housing arranged on the second vehicle part and the cable drum housing is guided on the adjustment part; and

an electromotive drive device for driving the cable drum.

2. The device as claimed in claim 1, wherein the cable drum has at least one fastening device for positive locking fastening of the traction cable to the cable drum.

3. The device as claimed in claim 1, wherein the cable drum has a first fastening device, into which a first portion of the traction cable can be placed in a positive locking manner, and a second fastening device, into which a second portion of the traction cable can be placed in a positive locking manner.

4. The device as claimed in claim 3, wherein the first portion and the second portion are formed by cable portions which are separate from each other.

5. The device as claimed in claim 1, wherein the cable drum housing engages around the adjustment part with at least one limb element and has a guide element which is guided on a side of the adjustment part that faces away from the cable drum.

6. The device as claimed in claim 5, wherein, on the side facing away from the cable drum, the adjustment part has at least one guide track in which the at least one guide element of the cable drum housing is guided.

7. The device as claimed in claim 1, wherein the traction cable is fixed at its first end and at its second end on the adjustment part in a non-positive locking or in a positive locking manner.

8. The device as claimed in claim 7, wherein the adjustment part has two fastening devices for fastening the ends of the traction cable to the adjustment part, wherein the fastening devices are offset with respect to each other along the longitudinal axis about which the cable drum is rotatable.

9. The device as claimed in claim 1, wherein a setting device is arranged on the adjustment part, on which setting device the first end or the second end of a force transmission element is arranged and which is adjustable for setting the length of the traction cable extending freely on the adjustment part between the first end and the second end.

10. The device as claimed in claim 1, wherein the drive device has a drive motor and a transmission coupling the drive motor to the cable drum.

11. The device as claimed in claim 10, wherein the transmission is switchable between:

a coupling state in which the drive motor is coupled to the cable drum,

a freewheeling state in which the coupling between the drive motor and the cable drum is interrupted in such a manner that the cable drum is movable independently of the drive motor, and

a braking state in which the cable drum is movable independently of the drive motor, but is braked in the process.

12. The device as claimed in claim 10, wherein the transmission is designed as a planetary gear transmission comprising:

a housing section,

a first planetary gear stage which has a first carrier element and at least one first planetary gear arranged on the first carrier element,

a second planetary gear stage which has a second carrier element and at least one second planetary gear arranged on the second carrier element,

a first ring gear part which is in toothing engagement with the at least one first planetary gear,

a second ring gear part which is in toothing engagement with the at least one second planetary gear, and

a drivable drive element,

wherein an adjustment force can be transmitted to the cable drum via the first planetary gear stage and the second planetary gear stage by driving of the drive element.

13. The device as claimed in claim 12, wherein the first ring gear part and the second ring gear part are connected to each other for conjoint rotation.

14. The device as claimed in claim 12, wherein the first planetary gear stage has a first sun gear which is in engagement with the at least one first planetary gear, and the second planetary gear stage has a second sun gear which is in engagement with the at least one second planetary gear and is different from the first sun gear, wherein, for transmitting an adjustment force from the drive element to the cable drum, one of the sun gears can be secured relative to the housing section and the other of the sun gears is connected to the cable drum for transmitting the adjustment force.

15. The device as claimed in claim 14, wherein the first carrier element and the second carrier element are connected to each other for conjoint rotation.

16. The device as claimed in claim 14, wherein at least one of

the first sun gear, the second sun gear and the cable drum are arranged on a common shaft which is rotatable about a longitudinal axis relative to the housing section,

the first sun gear and the cable drum are connected to the shaft for rotation therewith, and

the second sun gear is arranged rotatably on the shaft.

17. The device as claimed in claim 14, wherein the transmission has a switching device which has a brake pot connected to the second sun gear, and at least one switching element which is adjustable between a coupling position, a braking position and a freewheeling position and is arranged on a carrier.

18. The device as claimed in claim 17, wherein the second sun gear:

in the coupling position is held in place relative to the carrier by blocking contact of the at least one switching element against the brake pot,

in the braking position is movable in a braked manner relative to the carrier by braking contact of the at least one switching element against the brake pot, and

in the freewheeling position is freely movable relative to the carrier.

19. The device as claimed in claim 17, wherein at least one of

the switching device has an adjusting element, which is connected to an actuator and is drivable via the actuator, for adjusting the at least one switching element, and the switching device has at least one prestressing element prestressing the at least one switching element in the direction of the freewheeling position.
