Definitions

  • the invention relates to a device for covering the interior of a motor vehicle, in particular a window roller blind for a motor vehicle, with an extendable curtain and a tension rod fastened to the displaceable end of the curtain with a multi-part shaft mounted in the interior of the tension rod with a plurality of axially aligned partial shafts, each shaft end-side partial shaft has at its outer end a gear engaged with a rack.
  • Such covering devices are used, for example, to cover a loading space in motor vehicles, for example in so-called combination vehicles, or also to darken or shade windows of a motor vehicle.
  • a device of the type mentioned at the outset is known, for example, from DE 101 34 085 C1.
  • This device has a displaceable cover element which can be pulled out by means of a crossbar.
  • a drive motor is arranged in the central area of the crossbar.
  • the crossbar consists of two aligned partial rods, between which the motor is arranged.
  • the drive motor has a planetary gear on both sides with a drive shaft and a gearwheel arranged on the front side of this drive shaft.
  • the respective gearwheel meshes with a corresponding tooth profile. Due to the guidance on both sides by means of the tooth profiles and gear wheels as well as the propulsion on both sides, the displacement of the cover element is possible more evenly and less prone to failure.
  • the invention is therefore based on the problem of expanding the possible uses of cover devices in the interior of motor vehicles without increasing the susceptibility to malfunction.
  • the invention solves this problem in a device of the type mentioned at the outset in that at least two partial shafts are arranged so as to be axially displaceable relative to one another and all partial shafts are connected to one another in a substantially rotationally rigid manner.
  • the invention synchronizes the feed movement of the tension rod when pulling out and retracting the cover in both guides, each consisting of a toothed rack and a toothed wheel.
  • the invention ensures - by means of a torsionally rigid connection also of the mutually displaceable shaft sections or partial shafts - that when pulling out and retracting the cover the shaft mounted in the tension rod is rotated at both ends at the same rotational speed. Avoiding different rotational speeds of the gears at the shaft ends prevents the shaft from jamming in the guides.
  • This synchronized positive guidance of the shaft ends ensures alignment of the shaft in a predetermined position or direction.
  • the tension rod surrounding the shaft can no longer tilt or jam.
  • the axially displaceable partial shafts are arranged telescopically one inside the other. This arrangement allows a small-sized shaft. This is particularly advantageous because in the area of covers, in particular in the area of motor vehicle windows, the space available is regularly narrow.
  • the tension rod or the multi-part shaft is driven by a drive element guided on an, in particular, essentially linearly running path.
  • the drive element is particularly preferably guided only on one side of the tension rod or the multi-part shaft.
  • advantageously only one drive is required on only one side of the cover. This not only reduces costs, but also avoids complicated synchronization of two drives arranged on both sides of the tension rod or the multi-part shaft.
  • FIG. 1 a window blind for a motor vehicle according to an embodiment of the present invention.
  • the figure shows a device for covering the interior of a motor vehicle in the form of a window blind 1 which has a curtain 3 which can be pulled out from a winding device 2.
  • the curtain 3 is either translucent, but thereby reducing the light irradiation, or also opaque, in particular opaque.
  • Inside the winding device 2 there is a winding shaft which is mounted in a bearing arrangement.
  • the window blind is arranged in the area of a side window 4 of a motor vehicle.
  • the window roller blind can also be attached as a rear window roller blind or roof window roller blind.
  • the winding device 2 (viewed from the side) is arranged substantially vertically aligned with its longitudinal axis. In connection with the concept of vertical arrangement, inclinations of window surfaces in particular should be disregarded. “Vertical” is to be understood in particular in the sense that the longitudinal axis of the winding device is oriented essentially perpendicular to a lower edge 5 and / or an upper edge 6 of the window 4.
  • the curtain 3 can be pulled out of the winding device 2 by means of a pull rod 7 and possibly retracted, in particular with the support of a spring motor accommodated in the winding device 2.
  • the pull rod 7 is connected directly to the curtain 3.
  • the pull rod 7 is hollow.
  • a multi-part shaft with two or more part shafts 8, 9 is mounted in its interior.
  • the partial shafts 8, 9 are aligned axially with respect to one another and can be moved relative to one another, in particular telescopically displaceable. Despite the displaceability of the component shafts, however, all component shafts 8, 9 of the shaft arranged in the tension rod 7 are connected to one another in a rotationally rigid manner. This means that if one of the partial shafts, eg 8, is rotated, all other partial shafts, eg 9, rotate at the same speed of rotation.
  • the partial shafts 8, 9 are engaged, for example, via a tongue and groove connection running in the longitudinal axis, that a rotational movement of a shaft is also forcibly transmitted to the adjacent partial shaft.
  • the tongue and groove connections are designed such that the axial displaceability of at least two partial shafts 8, 9 is not impaired.
  • the end partial shafts 8, 9 each have at their free ends a gear 10, 11 connected to these partial shafts 8, 9 in a rotationally rigid manner. Each of these gears 10, 11 is in engagement with a corresponding rack 12, 13. These racks 12, 13 are fixedly attached to the motor vehicle in the region of the lower edge 5 and the upper edge 6 of the window 4.
  • the racks 12, 13 either run parallel or non-parallel to each other. Even if the toothed racks 12, 13 do not run parallel to one another, the toothed wheels 10, 11 remain in engagement with the toothed racks 12 and 13, respectively, since suitable side guides (not shown) on the toothed wheels 10, 11 and / or the toothed racks 12 , 13 and the axial displacement of the partial shafts 8, 9 prevents the gear wheels 10, 11 from slipping out of the racks 12 and 13, respectively.
  • a drive element 14 is provided which is operatively connected to the partial shaft 8.
  • the drive element 14 has a bearing, for example a bore, for receiving the end section of the partial shaft 8.
  • the drive element 14 is guided in a path 15 which runs along the lower edge 5 of the window 4 and is therefore essentially linear.
  • the drive element 14 itself is driven by a brush cable drive 16, which has a cable 17 and an electric motor 18.
  • the electric motor 18 is in engagement with the cable 17 in such a way that a rotary movement of the electric motor 18 is transformed into a longitudinal movement of the cable 17.
  • One end of the cable 17 can be wound up in the area of the electric motor 18.
  • the opposite end of the cable 17 is connected to the drive element 14, which as a result of a rotary movement of the electric motor and is moved.
  • the cable is housed in a flexible tube (not shown) or hose.
  • This arrangement of the cable 17 in a flexible hose means that the electric motor 18 can be arranged at various points, for example behind an inner door panel. This special drive therefore enables the drive 16 to be accommodated in a very flexible manner.
  • a single drive 16 is sufficient to extend and retract the curtain 3 evenly and safely by means of the pull rod 7.
  • the tension rod 7 is acted upon by the same force at both ends. In this way, the curtain 3 can be pulled out uniformly over its entire length. This not only enables the curtain 3 to be pulled out free of transverse stresses and thus wrinkles-free, but also enables safe and reliable largely trouble-free guidance of the tension rod 7 along the lower edge 5 and the upper edge 6 of the window 4.
  • a further curtain 19 is accommodated in the winding device 2 and can be wound up on a separate winding shaft.
  • the curtain 19 is preferably made of the same material as the curtain 3.
  • the curtain 19 generally has a different shape than the curtain 3, since it is adapted to a triangular section 20 of the window 4.
  • the curtain 19 likewise has a pull rod 21, which is connected by means of a further brush cable drive 22 to a further electric motor 23 via a further cable 24, which likewise runs in a hose, in a manner corresponding to the pull rod 7. is driven.
  • this second curtain 19 non-rectangular window shapes can be created almost completely.
  • the invention was explained on the basis of the figure on a window blind.
  • the device according to the invention can also be used in the area of cargo hold covers. It is therefore not limited to motor vehicle window blinds.
