Definitions

  • the present invention relates to a roller blind system according to the preamble of claim 1.
  • a generic roller blind system is known for example from DE 198 34 777 C2.
  • the roller blind disclosed therein has a roller blind, one end of which is fastened to a winding tube and the other end of which is provided with a draw bar.
  • the roller blind is wound on a winding tube, which coaxially receives a central winding shaft, which is connected to the winding tube via a torsion spring to ensure a constant torque between the winding tube and winding shaft and thus a constant bias of the roller blind for all extract positions of Rollo ⁇ .
  • the roller blind furthermore has a drive device with a bending and pressure-resistant drive element, preferably a tension- and pressure-resistant drive cable, which engages on the pull bar of the roller blind and moves it.
  • the drive element rotates the winding shaft and the winding tube at the same rotational speed.
  • a drive cable may alternatively be provided a rack or a toothed belt, which drives the winding shaft via a gear which meshes with the rack.
  • DE 19844 779 C1 discloses a roller blind system in which a conventional pressure-resistant threaded cable is used as the preferred displacement element for displacing a roller blind.
  • a toothed belt or rack arrangement is mentioned, but without reference to more details. th how to make such a toothed belt or rack assembly is received.
  • DE 101 55 167 A1 discloses a sunshade roller blind arrangement for a vehicle roof, in which the winding shaft is connected via a connecting gear to a drive shaft of a drive motor arranged coaxially with the winding shaft.
  • the drive motor may comprise a planetary gear, which is connected via a toothed belt with the winding shaft.
  • DE 32 11 467 A1 discloses an opening system for a sliding roof for motor vehicles in which in known manner for moving the sunroof a drive unit is provided, the rotatable output pinion two acting on both sides of the sunroof cover tensile and pressure-resistant output elements in opposite directions drives.
  • toothed belts which are accommodated in a slide-resistant manner are provided in a slide rail.
  • a disadvantage of the previously known solutions for driving roller blinds is that due to the flexurally rigid drive cable or rigid toothed rack or closed, circulating toothed belt, a large installation space is necessary to move these elements in the x-direction (vehicle longitudinal axis) and / or z - accommodate direction (vertical axis). In the case of long extension lengths of the roller blinds, increased friction also results due to the drive element in the guide rail, which leads to an increased expenditure of force for moving the roller blinds.
  • the present invention seeks to provide a roller blind of the type mentioned, in which On the one hand the necessary installation space is as small as possible and on the other hand, a movement of the blinds with the lowest possible expenditure of force and high com fort is allowed.
  • the deflection of a toothed belt according to the invention about a toothed wheel can be carried out with substantially smaller radii than in previously known roller blind systems with a deflected or wound tension- and pressure-resistant drive cable.
  • the solution according to the invention furthermore offers the advantage that, in contrast to previously known solutions with toothed racks, not only one tooth of the toothed wheel is in engagement, but the toothed wheel can engage in the toothed belt over a very large area of its circumference, which reduces the noise and further noticeably improves the quality impression.
  • the material expenditure is also reduced (only one deflection).
  • the use of meterware for the timing belt can achieve cost reductions because the same timing belts can be cut for different roofs.
  • FIG. 1 is a schematic, perspective view of a roller blind system according to the invention.
  • FIG. FIG. 2 is a side view of the shade system of FIG. 1 along the vehicle's longitudinal axis.
  • FIG. 1 shows a roller blind system according to the invention for moving a roller blind (not shown here), which is mounted so that it is fastened at one end to a rotatably mounted winding tube 10, which is only indicated schematically here.
  • the other end of the roller blind is connected to a pull bar 14, which is displaceably mounted by means of a guide rail 38.
  • a winding shaft 12 In ⁇ within the winding tube 10 is centrally located a winding shaft 12 which is connected to the winding tube only via a torsion spring 16.
  • the winding shaft is inserted into a star engagement 36, which in turn is in communication with a gear 20.
  • This toothed wheel 20 engages in an open, flexible and in a guide rail 30 drucksteif ge stored and displaceable toothed belt 18 a.
  • the second toothed belt end 24 is connected by means of a connection 26 to the pull bar 14 of the roller blind system.
  • the roller blind is mounted so that it communicates with its front edge with the Switzerlandspriegel 14 and with its rear edge with the winding tube 10 in conjunction.
  • the tension of the roller blind can be adjusted via a pretension of the torsion spring 16, which connects the winding tube 10 and the winding shaft 12. If the Switzerlandspriegel 14 and with him the roller blind pulled by hand or by means of an electric motor, so turns on the one hand the roller blind the winding tube 10 and on the other hand, the toothed belt 18 via the gear 20, the winding shaft 12. If the rotation paths of winding tube 10 and winding shaft 12 are the same, while the torsion spring 16 remains in its original state initial state of tension. Thus, the torsion spring 16 can be adjusted so that it holds the roller blind in a desired tension. In contrast to systems without additional, movable winding shaft, however, this does not allow the roller blind to snap back when the pull bow 14 is released. Thus, the roller blind system remains in any desired position without additional holding devices.
  • the gearwheel 20 is selected to be greater than the diameter of the winding shaft 12 including the completely wound roller blind, the winding shaft and the gearwheel are rotated at different rotational speeds due to the different diameters when the roller blind is pulled out (for example by pulling on the drawbar 14 manually) , Since the gear 20 is connected to the winding shaft 12, thus a relative movement between see the winding tube 10 of the winding shaft 12 forced, which provided between the winding tube 10 and the winding shaft 12 torsion spring 16 on the "basic tension" in the unwound state of the blinds When opening the roller blind (ie when winding the same), this additional tension is used to compensate for the higher actuation forces required when the roller blind is fully extended.
  • FIG. FIG. 2 shows a side view of the guide rails 30 and 38 of toothed belt 18 and tension bow 14, the latter being guided in its guide rail 38 by means of a slider 34.
  • the toothed belt 18 is guided in its guide rail 30 about the gear 20 so that a deflection of approximately 180 ° is realized.
  • the guide rail 30 of the toothed belt 18 serves to make the flexible, open (ie finite and not closed or circulating) toothed belt pressure-resistant. This compressive rigidity is necessary because, unlike a rotating toothed belt, the timing belt 18 is not only loaded on train, but also on pressure.
  • the guide rail 30 is preferably provided with a deflection guide 28 in the region of the toothed wheel 20.
  • the material of the deflection guide 28 must be designed for the lowest possible friction coefficient, which is why here POM (polyoxymethylene) with a proportion of PTFE (Teflon, polytetrafluoroethylene) or with a silicone component has proven ..
  • the connection 26, which as he ⁇ mentions the connection between the toothed belt 18 and the drawbar 14 represents molded onto the timing belt, or be pressed with him, welded or glued. Preferably, it has a tooth or lattice shape, in which the teeth of the toothed belt 18 can engage.
