DETAILED DESCRIPTION OF THE INVENTION

[0039] Using only schematic figures exclusively showing the essential portion of a cargo space cover the invention is now described based on two embodiments.

[0040] FIG. 1 illustrates a support device 10 configured as profile groove 11 which is configured by a side fairing element 12 of a motor vehicle. In this profile groove a first seat 13 is configured between a lower profile groove end 19 and an upper profile groove end 23 wherein a tension rod 14 of a cargo space cover is inserted into the first seat 13 in the pulled out position of the cargo space cover. Arranged in pull in direction E of the roller blind in front of the first seat 13 and thus transitioning into the lower profile grove end 19, the profile groove 11 includes an inlet 15 through which the tension rod 14 can be extracted from the profile groove or is insertable into the profile groove corresponding to the arrows EB indicating the insertion direction or the arrows AB defining the extraction direction. Eventually a slide 16 is supported in the profile groove 11 and movable by a positioning drive wherein the slide is provided with a lifting lug 17. The slide is arranged in FIG. 1 in its starting position at the upper profile groove end 23 from which it is movable in a direction towards the first seat 13 and back again from there.

[0041] In FIG. 2 the slide 16 was moved far enough in a direction towards the tension rod 14 within the profile groove 11 until the lifting lug 17 contacts the tension rod 14. Using the lifting lug 17 the tension rod is now pushed in pull out direction A of the roller blind from the first seat 13 and received by the slide 16. Thus, as evident from the comparing view of FIGS. 2, 3 and 4 a lifting surface 18 slides under the tension rod 14 and thus moves the tension rod 14 into a tension rod receiver of the slide 16. As soon as the tension rod 14 is inserted into the tension rod receiver of the slide 16 the position of the tension rod within the profile groove 11 is only determined by the position of the slide.

[0042] Using the motor driven slide 16 the tension rod 14 is freely movable within the profile groove 11. Thus, the position of the slide 16 arranged proximal to the first seat 13 at a lower profile groove end 19 defines the so called pull out or cover position of the roller blind in which the roller blind protects the cargo space of the station wagon from view when the hatch is closed.

[0043] Based on FIGS. 5 and 6 it is now illustrated how the slide 16 is moved back within the profile groove 11 in a direction of its starting position at the upper profile groove end 23 so that the tension rod 14 is moved into an intermediary position at least partially releasing the cargo space access. This process of moving the slide 16 in a direction of its starting position illustrated in FIG. 1 can be coupled with the opening process of the trunk hatch of the station wagon, however it is also conceivable that this movement of the slide 16 is decoupled from the opening process.

[0044] As evident from the FIGs. the tension rod can always be moved by hand back into the seat 13. It is also possible anytime to move the tension rod 14 out of the inlet 15 by hand in order to move the roller blind completely in pull in direction E and in order to completely release the cargo space.

[0045] FIGS. 7-12 illustrate a second embodiment of the invention. This embodiment is similar to the embodiment illustrated in FIGS. 1-6 in many respects, in particular with respect to structure and function. Also here the figures illustrate the support device 10 which is formed by a side fairing element 12 with a profile groove 11. This profile groove 11 forms a first seat 13 in which the tension rod 14 is inserted in FIG. 7. A slide 16 illustrated in FIG. 7 in a starting position at an upper profile groove end 23 also includes the described lifting lug 17 with the lifting surface 18. Differently from the first embodiment the first seat 13 defines a first intermediary position, the starting position of the slide 16 defines a second intermediary position of the tension rod 14 and thus of the roller blind. Also here the inlet 15 is not arranged in the portion of the pull out or cover position at a lower profile grove end 19 of the tension rod 14 but in the portion of the seat 13 forming a first intermediary position.

[0046] It is now illustrated in FIG. 8 that the slide was moved from its starting position in a direction towards the first seat 13 and reaches with its lifting lug 17 and the lifting surface 18 under the tension rod 14. The tension rod 14 is now disengaged from the first seat 13 in the pull out direction A of the roller blind as already described with reference to the first embodiment so that the tension rod is supported in the tension rod receiver of the slide 16. The slide 16 now moves further forward at the lower profile groove end 19 towards the pull out or cover position of the roller blind until the slide 16 has reached its pull out or cover position as illustrated in FIG. 9.

[0047] Like in the first embodiment the tension rod 14 is only moveable in a direction towards its starting position into an intermediary position at least partially releasing the cargo space by moving the slide 16 backward. This backward movement which can in induced by opening the hatch back or also independently therefrom is illustrated in FIG. 10. Therein the tension rod 14 that is supported by the slide 16 reaches approximately the first intermediary position illustrated in FIG. 7. During a further displacement of the slide 16 into its starting position illustrated in FIG. 7 the tension rod 14 follows the slide movement and thus moves into a second intermediary position which increases the access opening to the cargo space in size.

[0048] FIG. 12 furthermore illustrates the advantages of the inlet 13 arranged proximal to the first intermediary position. FIG. 12 illustrates schematically that cargo 20 is now arranged in the cargo space. The cargo 20 has a certain height which does not permit a backward movement of the tension rod 14 into the pull out or cover position at the lower profile groove end 19. In this case the tension rod 14 can be moved in a direction towards the inlet 15 by hand and can be removed from the profile groove by a corresponding extraction movement AB.

[0049] It is certainly conceivable to arrange an additional inlet in the portion of the pull out or cover position of the tension rod 14. Furthermore it is evident from the drawing description that an intermediary position of the tension rod 14 most convenient for the user or most appropriate for a loading position can be implemented for optimum coverage or optimum access to the cargo space by a respective control of the separate positioning drive operating the slide 16. Thus, the instant invention provides a high level of flexibility to select advantageous intermediary positions by using the separate positioning drive.

[0050] FIGS. 13-18 illustrate a third embodiment of the invention. FIG. 13 illustrates a side fairing 12 configured as a portion of a support device 10 and provided with a profile groove 11. The profile groove forms a first seat 13 where the pull out or cover position that can be assumed by the tension rod 14 is reached. Arranged thereafter in pull in direction E a first inlet 15 is arranged. FIG. 13 illustrates a second inlet 21 where the profile groove 11 forms a stop 22. This stop 22 provides a tactile identifier for reaching the extraction position when manually operating the tension rod 14.

[0051] Manually extracting the tension rod 14 from the second inlet 21 is illustrated in FIGS. 14 and 15. In FIG. 14 the tension rod 14 has been moved from a lower end of the profile grove at 19 in a direction towards the upper end of the profile groove 20 until the tension rod penetrates the stop 22. Following the pull of the winding shaft motor the winding shaft motor pulls the tension rod 14 out of the second inlet 21 and thus supports extracting the tension rod 14 from the profile groove 11.

[0052] The third embodiment, however illustrates an additional advantageous embodiment. Like in the remaining embodiments a slide 16 is supported in the profile groove wherein the slide 16 forms a lifting lug 17 and provides a receiver for the tension rod 14. Starting from a starting position at the upper profile groove end 23 the slide moves towards the lower profile groove end 19, wherein the slide keeps the tension rod 14 in the tension rod receiver. At the lower profile groove end 19 the tension or cover position of the roller blind is reached. Returning the roller blind into an intermediary position making the cargo space partially accessible is performed by moving the slide 16 in a direction towards the upper profile groove end 23.

[0053] The slide 16, however, is supported by a spring element 24 and is movable against the spring force of the spring element 24 about a defined distance in a direction towards an intermediary position or in a direction towards an upper profile groove end. When this is done as illustrated in FIG. 17 the tension rod 14 can be extracted through the first inlet 15 from the profile groove 11. The first inlet 15 is thus arranged subsequent to the lower profile groove end 19 in a direction towards the upper profile groove end 23. The extraction movement of the tension rod 14 through the first inlet 15 is illustrated in FIG. 18. This provides that the tension rod 14 can also be extracted from the profile groove 11 in case the positioning drive has failed.
