32. A device for manually and/or electromotively adjusting or securing a first vehicle part and a second vehicle part relative to each other, 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,

an output element which is to be arranged on the second vehicle part, is operatively connected to the adjustment part and is drivable in order to move the adjustment part relative to the second vehicle part, and

an electromotive drive device for driving the output element, wherein the drive device has a drive motor and a transmission coupling the drive motor to the output element,

wherein the transmission has a switching device which has a coupling element assigned to a transmission element of the transmission, and at least one switching element which is adjustable between a coupling position, a braking position and a freewheeling position, for acting on the coupling element such that, by means of the switching device, the transmission is switchable between

a coupling state in which the drive motor is coupled to the output element,

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

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

33. The device as claimed in claim 32, wherein the transmission element in the coupling position is held in place relative to a stationary carrier, on which the at least one switching element is arranged, by blocking contact of the at least one switching element against the coupling element,

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 coupling element, and in the freewheeling position is freely movable relative to the carrier.

34. The device as claimed in claim 32, wherein the switching device is designed in order

to keep the at least one switching element in contact with the coupling element with a predefined maximum force in the coupling position and

with a force which is reduced in relation to the maximum force in the braking position.

35. The device as claimed in claim 32, wherein 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.

36. The device as claimed in claim 32, wherein the transmission is designed as a planetary gear transmission.

37. The device as claimed in claim 36, wherein the planetary gear transmission is of single stage design, comprising

a housing section,

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

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

a drivable drive element,

wherein an adjustment force can be transmitted to the output element via the planetary gear stage by driving of the drive element.

38. The device as claimed in claim 37, wherein the planetary gear stage has a sun gear which is in engagement with the at least one planetary gear and is connected to the drive element for rotation therewith.

39. The device as claimed in claim 37, wherein the drive element is in toothing engagement with a drive worm and is drivable via the drive worm.

40. The device as claimed in claim 36, wherein the planetary gear transmission is of two stage design, 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 output element via the first planetary gear stage and the second planetary gear stage by driving of the drive element.

41. The device as claimed in claim 40, wherein the first ring gear part and the second ring gear part are connected to each other for conjoint rotation.

42. The device as claimed in claim 40, 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 output element, one of the sun gears can be secured relative to the housing section and the other of the sun gears is connected to the output element for transmitting the adjustment force.

43. The device as claimed in claim 42, wherein the first carrier element and the second carrier element are connected to each other for conjoint rotation.

44. The device as claimed in claim 42, wherein the first sun gear, the second sun gear and the output element are arranged on a common shaft which is rotatable about a longitudinal axis relative to the housing section.

45. The device as claimed in claim 44, wherein at least one of

the first sun gear and the output element are connected to the shaft for rotation therewith and

the second sun gear is arranged rotatably on the shaft.

46. The device as claimed in claim 42, wherein the coupling element is connected to the second sun gear which realizes the transmission element.

47. The device as claimed in claim 46, wherein the second sun gear

in the coupling position is held in place by blocking contact of the at least one switching element against the coupling element,

48. The device as claimed in claim 32, further comprising a flexible force transmission element which is fastened at a first end and at a second end to the adjustment part in such a manner that, during a rotational movement of the output element, the force transmission element rolls on the output element and thereby adjusts the output element relative to the adjustment part.
