Definitions

  • the invention relates to a shading arrangement for a transparent roof section of a motor vehicle with the features of the preamble of claim 1.
  • Such a shading arrangement is known from the publication DE 102014 108 119 A1 and is designed as a roller blind arrangement, which comprises a roller blind strip as a shading element, which can be adjusted between a shading position and a release position.
  • the transparent roof section is completely filled by the roller blind.
  • the roller blind In the release position, the roller blind at least partially releases the transparent roof section.
  • the roller blind At its lateral edges in relation to a longitudinal central plane of the roof, the roller blind is guided in each case in a roof-mounted guide rail which laterally delimits the transparent roof section. The lateral guidance of the roller blind can keep it taut in the transverse direction of the roof in its areas unwound from a roller blind.
  • This shading arrangement further comprises a lighting device which has lighting means which are received by a respective channel of the guide rails which lies in a plane which is arranged above the shading element.
  • the shading element can be illuminated from above by means of the lighting means, so that a light pattern is generated on the shading element that is visible from the vehicle interior. If the shading element is moved into a release position, however, there is a risk that when the light source is activated, the light then entering the vehicle interior directly is disruptive for vehicle occupants.
  • the invention is based on the object of creating a shading arrangement designed according to the generic type mentioned in the introduction, in which the lighting means in can be operated in any position of the shading element without the risk of dazzling or disturbing vehicle occupants.
  • a drive means which ensures that the lighting means cannot shine directly into a vehicle interior, since it is blinded when the roof section is open or partially opened, i.e. when the shading element is moved into a release position. Direct lighting into the vehicle interior is therefore excluded.
  • the lighting means which in particular forms a light guide, is therefore not visible to a vehicle occupant in any position of the shading element. It is prevented that the lighting means in the open or partially opened state of the roof section shine in a disruptive manner in the vehicle interior. It is of course conceivable in a special embodiment that light that is emitted by the light guides falls obliquely through the released section into the vehicle interior without disturbing the vehicle occupants or striking them directly.
  • the drive means drives the lighting means so that it is displaced in the channel of the relevant guide rail when the shading element is adjusted.
  • the lighting means is brought into a release position out of the field of vision of a vehicle occupant.
  • the drive means comprises a coupling device between the shading element and the lighting means.
  • the lighting means is displaced through the shading element itself and brought out of the field of vision of the vehicle occupants when this is moved into a release position.
  • a separate actuating element can also be provided, which is part of the drive means and acts on the lighting means when the shading element is adjusted.
  • the drive means drive a screen for the illuminant, which moves in front of the illuminant when the shading element is adjusted from the shading position into the release position.
  • the drive means that drives the screen can in particular comprise a coupling device between the shading element and the screen. A movement of the shading element is then transmitted directly to the panel via the coupling device.
  • a separate actuating element is provided which is part of the drive means and which drives the diaphragm when the actuating element is adjusted.
  • the screen which can be moved in front of the lamp, can be a strip of material made of an opaque material, which is guided in a separate guide track of the guide rail in question. It is also conceivable that the diaphragm encompasses the lighting means in the manner of a longitudinally slotted tube and is pulled or pushed over the lighting means for blending. When the shading element assumes its shading position in which the transparent roof section is completely covered, the screen releases the illuminant. The panel is then preferably received by a storage space which can be formed by a guide.
  • the diaphragm can also be arranged as a roll on a winding device.
  • the shading element of the shading arrangement according to the invention is in particular a roller blind which is provided with a tension bow and which, in its release position, is wound up to form a roller blind. It is also conceivable for the shading element to be designed as a web of material which, when it is adjusted into the release position, is introduced into a receiving space of the relevant vehicle roof and deflected.
  • the coupling device which is connected to the illuminant or to the panel, is preferably connected to the tension bow, which then also drives or takes along the illuminant or the panel.
  • FIG. 1 shows a schematic plan view of a roof of a motor vehicle with a shading arrangement according to the invention
  • FIG. 2 shows a schematic plan view of the shading arrangement of the roof according to FIG. 1 on its own;
  • Figure 3 shows a section through the shading arrangement according to Figure 2 along the
  • FIG. 4 shows a section corresponding to FIG. 3 through an alternative embodiment of a shading arrangement according to the invention
  • FIG. 5 shows a plan view of a further embodiment of a shading arrangement according to the invention.
  • FIG. 6 shows a section through the shading arrangement according to FIG. 5 along the line VI-VI in FIG.
  • a vehicle roof 10 of an otherwise not shown passenger car which has a roof cutout 12 which can be closed by means of a transparent cover element (not shown) of a roof opening system. By moving the cover element, the roof cutout 12 can be at least partially released.
  • the vehicle roof can also be designed without a movable cover element, i.e. as a pure fixed roof.
  • the vehicle roof comprises a transparent fixed roof element which forms a transparent roof section and is firmly connected to the vehicle body.
  • the vehicle roof 10 comprises for shading the roof section 12, which represents a transparent roof section regardless of the position of the cover element a roller blind arrangement 14 which represents a shading arrangement and which has a roller blind strip 16 made of a foldable or windable fabric as a shading element.
  • the roller blind 16 On its free end face, the roller blind 16 has a tension bow 18, the drive of which can be used to adjust the roller blind between a shading position that completely covers the roof cutout 12 and a release position that at least partially exposes the roof cutout 12.
  • the roller blind 16 At its edge facing away from the tension bow 18, the roller blind 16 can be wound up to form a roller blind 20, which is arranged in particular on a winding shaft extending in the transverse direction of the vehicle.
  • the tension bow 18 is released or when the tension bow 18 is displaced in the direction of the winding shaft, the roller blind 16 automatically winds up to form the roller blind 20.
  • the roller blind 16 and the tension bow 18 are guided on both sides in a roof-mounted guide rail 22A or 22B, which extends along a lateral edge of the roof cutout 12 or laterally delimits it, based on a vertical longitudinal central plane.
  • the guide rails 22A and 22B can be part of the roof opening system (not shown in more detail) or only be assigned to the roller blind arrangement 14.
  • the roller blind arrangement 14 can have a drive motor which drives the tension bow 18 via drive cables (not shown in detail).
  • the roller blind arrangement 14 can also be actuated purely manually, namely in that the tension bow 18 is manually displaced in the guide rails 22A and 22B in the longitudinal direction of the roof.
  • the roller blind 16 is made of a material which has an underside facing a vehicle interior and an upper side facing the vehicle surroundings and has a certain transparency. A layer of a phosphorescent or fluorescent paste can be applied to the fabric on the upper side. It is also conceivable that the fabric of the roller blind 16 comprises a woven-in light effect fabric or the like. As can be seen in particular from FIGS. 2 and 3, the guide rails 22A and 22B each have a channel 24 which extends in the longitudinal direction and in which a light guide 26 is received.
  • the channel 24, which lies in a plane which is arranged above the roller blind 16, is open in the direction of the roller blind 16, so that light, which can be coupled into the respective light guide 26 by means of an LED arrangement 28, in the direction of the roller blind 16 can be emitted, whereby a light pattern visible from the vehicle interior is generated on the roller blind 16.
  • the blind arrangement 14 has a screen 30 for each of the two light guides 26, which is designed in the manner of a longitudinally slotted tube and with its longitudinal edges is guided in guide tracks 32 and 34 of the relevant guide rails 22A and 22B, respectively.
  • the cover 30 is provided with a drive means which comprises a coupling device 36 which is fixed on the one hand to the cover 30 and on the other hand is connected to the tension bow 18 of the roller blind 16.
  • the panels 30 connected to the tension bow 18 via the coupling device 36 are displaced on the guide rails 22A and 22B in such a way that the light guide areas that lie next to the roller blind 16 are released and the areas of the light guides 26 which lie next to the areas of the roof cutout 12 released by the roller blind 16 are covered.
  • the tension bow 18 is displaced in the direction of the rear of the vehicle, the panels 30 are therefore pulled backwards into the guide rails 22A and 22B.
  • the panels 30 are arranged at the front of the guide rails 22A and 22B and are accommodated in a corresponding storage space or storage guides, which are not specified here.
  • a vehicle roof is of course also conceivable in which a roller blind is pulled out towards the rear in order to shade a transparent roof section. Then the panels are pulled into the guide rails from behind in the direction of the vehicle front, with a storage space or storage guides for the panels being arranged on the rear of the guide rails.
  • a roller blind arrangement according to the invention is shown, which largely corresponds to that according to Figures 2 and 3, but differs from this in that it comprises strip-shaped panels 30, which in guide tracks 32 and 34 of the relevant guide rail 22A or 22B and, corresponding to the embodiment according to FIGS. 2 and 3, each blind a lighting means formed from a light guide 26 in areas that are next to sections of the roof cutout 12 that are exposed by the roller blind 16.
  • the areas of the light guides 26 which lie next to the roller blind 16 can emit light onto the roller blind 16 when the LED arrangements 28 are activated. Vehicle occupants can therefore not be disturbed by the light emitted by the light guides 26, even when the roof cutout 12 is open or partially open.
  • FIG. 4 corresponds to that according to FIGS. 2 and 3, for which reason reference is made to the relevant description.
  • a roller blind arrangement 14 which also includes a roller blind 16, which is adjustable between a shading position covering a roof cutout 12 and a release position at least partially exposing the roof cutout and has a tension bow 18 for adjustment.
  • the roller blind 16 and the tension bow 18 are also guided in lateral guide rails 22A and 22B.
  • the guide rails 22A and 22B each have a channel 24 in a plane which lies above the roller blind 16, in which a light guide 26 is received as a light source. Light from an LED arrangement 28 can be coupled into each of the light guides 26.
  • the light guides 26 can be displaced in the channels 24 of the guide rails 22A and 22B in the longitudinal direction of the blind.
  • the light guides 26 When moving, the light guides 26 can be introduced into rear guides 38 which are formed in the vehicle roof 10.
  • the roller blind 16 always forms a screen for the light guides 26, so that these are not visible to vehicle occupants. The vehicle occupants can therefore not be dazzled by the light emitted by the light guides 26.
  • the tension bow 18 is actuated, the light guides 26 in the channels 24 of the guide rails 22A and 22B are shifted directly in the longitudinal direction of the roof, so that the light guides 26 in the area of the roof cutout 12 are only arranged in the areas that are also shaded by the roller blind 16 .
  • the areas of the roof cutout 12 that are released from the roller blind 16 are not illuminated by the light guides 26, the rear areas of which lie outside the guide rails 22A and 22B and are accommodated by storage spaces formed by the guides 38.
