Definitions

• the invention relates to an actuating device for adjusting a cover, in particular a sunroof of a vehicle according to the preamble of claim 1.
• An actuating device is already known (DE-PS 33 16 653) in which a pinion is in engagement with two cables on both sides, to move the two cables parallel to each other when rotating the pinion.
• the pinion is driven by a drive device via a gear.
• the two cables have coils that extend helically along the cable to engage a corresponding one in engagement with the teeth of the pinion when the pinion is rotated
• the two cables are attached to a cover or to a sunroof of a vehicle, so that the sunroof can be opened or closed depending on the direction of rotation of the pinion.
• the force transmission can only take place with a shock.
• a power transmission subject to impacts leads to disturbing noises.
• the actuating device according to the invention with the characterizing features of claim 1 has the advantage that the adjustment of the helix or the cable is carried out continuously, so that there are no more interference, which can avoid disturbing noises.
• FIG. 1 shows a section of a sunroof with the inventive
• Actuating device, Figure 2 in a schematically simplified representation as an example the structure of the actuating device according to the invention.
• FIG. 1 shows a section of a vehicle roof 3 of a vehicle, for example a motor vehicle.
• the vehicle roof 3 has an opening 5, which from a Cover 7, which is referred to below as a sunroof, can be opened or closed more or less.
• cables 14 and 15 act on it at two points of attack 9 and 10, which are moved by an actuating device 18 in the direction of arrows 20, 21, for example, to close the sliding roof 7 in the direction of a drawn arrow 19.
• the cables 14, 15 are designed to be flexible and can transmit forces in both the pulling and pushing directions.
• the cables 14 and 15 have an outer profile which, as shown in simplified form in FIG. 1, is in the form of a coil 23 or 24.
• the coils 23, 24 are helical structures that surround an outer surface of the cables 14 and 15 like a thread or a spindle.
• the cables 14, 15 equipped with these outer profiles thus form quasi bendable racks.
• the construction of such cables 14, 15 is well known to the person skilled in the art and can be found, for example, in German specification DE 1 525 115.
• two wheels 25 and 26 are provided, which are preferably designed as gear wheels. Both wheels 25, 26 or gears mesh with each other, for example. It is also conceivable to use friction instead of gearwheels to transfer the rotational movement of the driven wheel 26 to the other wheel 25 to be driven, which are made of a corresponding material such as elastic plastic or rubber.
• the wheels 25 and 26 have an opening 28 and 29 in their center. In the openings 28 and 29 are the Cables 14 and 15 with their coils 23, 24 partially.
• the openings 28 and 29 have inner walls 31 and 32, respectively, which have an inner profile 33 and 34, respectively.
• the inner profiles 33 and 34 engage in the outer profiles or in the coils 23, 24 of the cables 14, 15 in order to
• the inner profiles 33, 34 are helical structures which engage in the form of an internal thread on the circumference of the coils 23, 24 of the cables 14, 15. With their openings 28 and 29, the two wheels 25 and 26 thus form hollow spindle wheels, the cables 14 and 15 being actuated like lifting or pulling spindles. Since the outer profiles or the spirals 23, 24 of the cables 14 and 15 are constantly in engagement with the inner profiles 33, 34 of the openings 28, 29, there can no longer be any engagement impacts, so that
• a gear which has a worm 39 which engages in a toothed wheel 40 in order to bring about a corresponding reduction.
• the gear 40 is rotatably, for example, in one piece with the same axis of rotation
