Abstract

A shading system for a split side window of a vehicle, including a main shading structure held on a main winding shaft for movement between a stowed position and a shading position, and an auxiliary shading structure held on an auxiliary winding shaft for movement between a stowed position and a shading position. The main shading structure has a main pull-out profile on an end region and the auxiliary shading structure has an auxiliary pull-out element on an end region, which are lengthwise displaceable in vehicle-fixed guiding tracks for displacement between the stowed and shading positions. The main pull-out profile and the auxiliary pull-out element are guided on one side in adjacent guiding tracks extending in parallel to each other, and the main pull-out profile is associated with a drag device entraining the auxiliary pull-out element during a longitudinal displacement from the stowed position to the shading position.

First claim

The invention claimed is:

1. A shading system for a split side window of an automotive vehicle, comprising a main shading structure supported on a main winding shaft for winding up and off between a stowed position and a shading position, an auxiliary shading structure supported on an auxiliary winding shaft for winding up and off between a stowed position and a shading position, the main shading structure having an end region that is a leading end region of the main shading structure during unwinding of the main shading structure from the main winding shaft in a winding off direction, the main shading structure having a main pull-out profile on the leading end region thereof, the main pull-out profile being dimensionally stable and extending along substantially an entire widthwise extent of the main shading structure, the auxiliary shading structure having an end region that is a leading end region of the auxiliary shading structure during unwinding of the auxiliary shading structure from the auxiliary winding shaft in a winding off direction, the auxiliary shading structure having an auxiliary pull-out element on the leading end region thereof, the main pull-out profile and the auxiliary pull-out element being displaceable in vehicle-fixed rails between the respective stowed and shading positions, the main pull-out profile and the auxiliary pull-out element each being respectively guided on one side in first and second ones of the rails, the first and second rails being disposed immediately sidewardly adjacent one another and extending parallel to each other, the shading system further comprising a drag device associated with the main pull-out profile, the drag device entraining the auxiliary pull-out element during a displacement of the main shading structure from the stowed position thereof to the shading position thereof, the second rail defining therein a guiding track which is substantially linear, and the auxiliary pull-out element is guidably supported in the guiding track of the second rail for substantially linear movement therealong during a displacement of the main shading structure from the stowed position thereof to the shading position thereof.

2. The shading system according to claim 1 , wherein the drag device includes at least one entrainer element disposed on the main pull-out profile and/or on the auxiliary pull-out element, the entrainer element being configured for entraining the auxiliary pull-out element in a form-fitting manner during displacement of the main shading structure from the stowed position to the shading position.

3. The shading system according to claim 2 , wherein the at least one entrainer element is positioned on a side of the first and second guiding rails.

4. The shading system according to claim 1 , wherein the first and second rails both extend substantially linearly and substantially in a vertical direction of a split side window of an automotive vehicle.

5. The shading system according to claim 1 , wherein the drag device includes mutually complementary entrainer elements respectively disposed on the main pull-out profile and on the auxiliary pull-out element, each entrainer element projecting into a trajectory of the other entrainer element.

6. The shading system according to claim 1 , further comprising a drive system for displacing the main pull-out profile between the stowed position and the shading position of the main shading structure in a forcedly guided manner.

7. The shading system according to claim 1 , further comprising a return spring device associated with the auxiliary winding shaft to apply torque thereto in a winding-up direction.

8. The shading system according to claim 1 , further comprising a mechanical coupling device coupling the main pull-out profile to the auxiliary pull-out element during displacement from the shading position in a direction towards the stowed position.

9. The shading system according to claim 8 , further comprising a mechanical control device associated with the mechanical coupling device to decouple the auxiliary pull-out element from the main pull-out profile in response to the auxiliary pull-out element reaching the stowed position thereof.

10. The shading system according to claim 9 , wherein the second rail associated with the auxiliary pull-out element includes, in a region of the stowed position of the auxiliary shading structure, a control contour fixed in location relative to the second rail, the control contour cooperating with a movable coupling member of the mechanical coupling device in response to a direction of movement of the auxiliary pull-out element in such a manner that the auxiliary pull-out element is decoupled from or coupled to the main pull-out profile.

11. The shading system according to claim 1 , wherein the auxiliary shading structure includes at least one reinforcement strip oriented transversely to a direction of displacement of the auxiliary shading structure.

12. The shading system according to claim 1 , further including a control device configured to decouple the auxiliary pull-out element from the main pull-out profile in response to the auxiliary pull-out element reaching the stowed position thereof.

13. The shading system according to claim 1 , further including a coupling and decoupling arrangement which couples said main pull-out profile to said auxiliary pull-out element during displacement of said main pull-out profile from the shading position to the stowed position, and which decouples said auxiliary pull-out element from said main pull-out profile when said auxiliary pull-out element reaches the stowed position thereof.

14. The shading system of claim 13 , wherein said main pull-out profile has an end guidably supported on said first rail and said auxiliary pull-out element has an end guidably supported on said second rail, said drag device includes a first entrainer element fixed to said end of said main pull-out profile and a second entrainer element fixed to said end of said auxiliary pull-out element, said first and second entrainer elements being configured and disposed to cooperatively engage one another during displacement of said main pull-out profile from the stowed position to the shading position thereof, said coupling and decoupling arrangement includes a latch member movably mounted on said end of said auxiliary pull-out element, said latch member having a surface disposed in vertically-spaced relation with said second entrainer element, said first entrainer element being disposed between said surface and said second entrainer element to couple said main pull-out profile to said auxiliary pull-out element during displacement of said main pull-out profile from the shading position thereof towards the stowed position thereof, said coupling and decoupling arrangement further including a stop member disposed adjacent said second rail and being non-movable relative thereto, said stop member defining an end stop for said auxiliary shading structure in the stowed position thereof, said stop member defining a control contour thereon, said control contour being configured to move said surface of said latch member out of engagement with said first entrainer element to decouple said auxiliary pull-out element from said main pull-out profile as said auxiliary shading structure approaches the stowed position thereof.

15. A shading system for a split side window of a vehicle, said shading system comprising:
a main winding shaft;
a flexible and sheet-shaped main shading structure having a first end region and a second end region spaced therefrom along a lengthwise extent of said main shading structure, said main
