[0038] Now, a shading device 20 for a vehicle and a vehicle door 100 including the shading device 20 according to an exemplary embodiment of the present invention will be described with reference to the accompanying drawings. The vehicle may be a motor vehicle, in particular a passenger car, such as a purely internal combustion engine driven, purely electric or hybrid motor vehicle. Alternatively, the vehicle may also be a truck or a rail vehicle. In the illustrated embodiment, the vehicle door is a frameless vehicle door, and the body 10 of the vehicle door 100 is schematically described, and the window glass not shown can extend from the body 10 in a substantially vertical direction and can be returned to the body 10 in the opposite direction. In an embodiment not shown, the vehicle door may also be a conventional framed vehicle door. In the illustrated embodiment, the shading device is configured for a vehicle door, in particular a frameless vehicle door. However, in an embodiment not shown, the shading device may also be configured for a windshield or a sunroof.

[0039] The shading device 20 comprises a blind assembly 8, which comprises a housing 9, a blind 11 and a pulling element 12, which can be arranged on the free end of the blind 11. The blind 11 can be stored in the housing 9, in particular in a rolled-up manner. For this purpose, a reel can be provided in the housing 9, onto which the blind 11 can be rolled. Alternatively, the blind 11 can be self-winding, and thus a separate reel can be omitted. Alternatively, the blind 11 can be stored in the housing 9 in a Z-folded manner. Alternatively, the blind assembly can also be constructed without a housing.

[0040] In such Figure 1 In the first state shown, the sunshade assembly 8 is in the region of the body 10 of the vehicle door 100, in particular is accommodated in a concealed manner in the body 10, i.e. in a first position, wherein the sunshade 11 is stowed, in other words, is stored in the housing 9. Advantageously, with reference to the longitudinal direction of the vehicle, the sunshade assembly 8 is arranged in the region of the vehicle door close to the rear edge and can be deployed from the rear to the front, wherein in the fully deployed state, the tension element 12 is arranged in the region of the vehicle door close to the front edge.

[0041] In such Figure 2 In the second state shown, the shading device 20 has been lifted in a first direction Z, in particular substantially vertically, from a first position to a second position and is held in the second position, wherein the shading device 20 is located in the region of the vehicle window in the vertical direction of the vehicle.

[0042] In such Figure 3 In the third state shown, the blackout curtain 11 is completely unfolded in the second direction X, in particular in the substantially longitudinal direction. It goes without saying that the blackout curtain 11 can be partially unfolded according to actual needs.

[0043] The shading device 20 has a drive 4, which is in particular an electric motor, such as a DC motor. The shading device 20 also has a flexible shaft 5, which can have a drive end 13. The drive 4 is configured to deliver the flexible shaft 5 so as to allow the shading device 20 to move from Figure 1 The initial state shown is driven to Figure 3 and configured to retract the flexible shaft 5 so as to allow the shading device 20 to return to the final state shown; Figure 1 The initial state is shown.

[0044] If Figure 1 and Figure 2 It can be seen that the shading curtain assembly 8 can be linearly moved between the first position and the second position in the first direction Z when the shading curtain 11 is retracted. To this end, the shading device 20 has a first linear guide device 1. Figure 1 Starting from the first position of the blackout curtain assembly 8 shown, the drive 4 can be activated to deliver the flexible shaft 5 toward the blackout curtain assembly 8, and the driving end 13 of the flexible shaft 5 acts on the blackout curtain assembly 8, for example, directly or indirectly on the housing 9 of the blackout curtain assembly 8, and the flexible shaft 5, more specifically, the driving end 13 of the flexible shaft 5 and a section adjacent to the driving end 13, are guided by the first linear guide device 1 until the blackout curtain assembly 8 is driven from the first position to the second position in the first direction Z.

[0045] like Figure 4 and Figure 5 As shown, when the shade assembly 8 reaches the second position, the flexible shaft 5 operates the locking device 6 with its driving end 13, so that the locking device 6 is switched from the unlocked state to the locked state. The locking device 6 can lock the shade assembly 8 in the second position in the locked state. Conversely, the locking device 6 can release the shade assembly 8 in the unlocked state. In the embodiment shown, the locking device can be constructed according to the principle of the pressing mechanism of a ballpoint pen, and can be switched from one state of the locked state and the unlocked state to the other state each time it is pressed.

[0046] Alternatively, the locking device can be configured as an electromagnetic device, wherein the blind assembly 8 can be held in the second position by magnetic attraction in the power-on state, and the blind assembly 8 can be released in the power-off state. Alternatively, the locking device can also be configured as an electrical locking device, wherein the armature is locked when the power is on and unlocked when the power is off.

[0047] The shading device 20 also has a second linear guide 2, which extends transversely to the first linear guide 1, and the first linear guide 1 has an opening 16 leading to the second linear guide (see Figure 5 ). Figure 4 and Figure 5 In the state shown, the driving end 13 of the flexible shaft 5 is located near the opening 16. Figure 2 In the state shown, the drive end 13 of the flexible shaft 5 has passed through the opening 16 and is engaged with the pull element 12 of the blind assembly 8. In order for the drive end 13 of the flexible shaft 5 to engage with the pull element 12, the pull element 12 may have a recess 14. The drive end 13 can enter the recess 14 and remain in the recess 14 while overcoming a predetermined resistance. In order to provide a suitable resistance, a resistance element 15 (see Figure 5 ), the resistance element 15 is configured to hold the pulling element 12 when the driving end 13 enters the recess 14. The resistance element 15 can be, for example, a magnet and / or a spring-loaded steel ball and / or an elastically deformable protrusion.

[0048] Now, in the second position of the blind assembly 8, starting from the stowed state of the blind 11, the flexible shaft 5 is further delivered by the drive 4, and the flexible shaft 5 is guided by the first linear guide device 1 and the second linear guide device 2, more specifically, the drive end 13 of the flexible shaft 5 and the first section adjacent to the drive end 13 are guided in the second linear guide device 2, and the second section of the flexible shaft 5 adjacent to the first section is guided in the first linear guide device 1. With the help of the drive 4 and the flexible shaft 5, the pulling element 12 is driven, so that the blind 11 can be driven in the second direction X from the stowed state until as shown in FIG. Figure 3 Shown in the expanded state (fully expanded state).

[0049] For better operation of the blind assembly 8, the blind device 20 may further include a third linear guide 3, which is configured to guide the tension element 12 in the first direction Z and move together with the tension element 12 in the second direction X. Advantageously, the third linear guide 3 includes a guide element 7 suspended on the second linear guide 2 and movable in the first direction Z, and the tension element 12 can be linearly moved relative to the guide element 7 in the first direction Z. Particularly advantageously, the third linear guide 3 is configured such that, during the driving of the blind assembly 8 from the first position to the second position, first, the guide element 7 is stationary and the tension element 12 is linearly moved in the first direction Z until the tension element 12 abuts against the guide element 7 in the first direction Z, and then, the guide element 7 and the tension element 12 are linearly moved together in the first direction Z until the guide element 7 abuts against the second linear guide 2 in the first direction Z, at which time the blind assembly 8 reaches the second position.

[0050] exist Figure 6, a cross-sectional view of an exemplary third linear guide 3 is shown in FIG. The pull element 12 has a C-shaped cross section, and the guide element 7 has an I-shaped cross section. The guide element 7 can move linearly relative to the pull element in the first direction Z, and cannot move relative to each other in a plane perpendicular to the first direction Z. The pull element 12 can have a stopper for achieving the stop of the pull element 12 on the guide element 7. The guide element 7 can have another stopper for achieving the stop of the guide element 7 on the second linear guide 2.

[0051] From Figure 3 Starting from the fully extended state of the blackout curtain 11 shown, by appropriately retracting the flexible shaft 5 with the drive 4, since the driving end 13 of the flexible shaft 5 remains engaged with the recess 14 of the pulling element 12, the pulling element 12 can be partially pulled back along the second linear guide device 2, so that the blackout curtain 11 is converted from the fully extended state to the partially extended state.

[0052] By further retracting the flexible shaft 5 with the drive 4 until the flexible shaft 5 reaches the position as shown in FIG. Figure 2 The state shown, in which the blackout curtain 11 is substantially in the stowed state. Next, the drive end 13 of the flexible shaft 5 is pulled out of the recess 14 of the pulling element 12, and the locking device 6 is operated again, so that the locking device is switched to the released state.

[0053] Now, by further retracting the flexible shaft 5 by the drive 4, the entire blind assembly 8 and the third linear guide 3 gradually return to the position as shown below under the effect of gravity. Figure 1 The initial state is shown.
