DETAILED DESCRIPTION

[0043] A motor vehicle 1 in the form of a van has a vehicle interior, which is composed of a passenger compartment and a rear loading space 2 which adjoins the passenger compartment. Rear access to the loading space 2 can be closed off by a tailgate 3. Assigned to the loading space 2 is a covering apparatus 4, as described in more detail below on the basis of FIGS. 2 to 19.

[0044] The covering apparatus 4 has a covering arrangement which is formed by a plurality of slats 7 and can be displaced between a compactly stowed inactive position and an extended covering position, shown in FIG. 1. The slats 7 of the covering arrangement are guided and supported in their covering position in oppositely situated lateral guides 5 that are fixed to the vehicle. The oppositely situated lateral guides 5 are respectively provided in a side wall of the loading space 2 and fixedly connected to load-bearing structural parts of the body of the motor vehicle 1 in a manner not illustrated in more detail, in order to allow a crash-proof arrangement of the lateral guides 5 in the side walls of the loading space 2.

[0045] The covering arrangement of the covering apparatus 4 is accommodated in a receiving space 9 of a cassette housing 6, which is likewise arranged fixed to the vehicle, in the compactly stowed inactive position. The cassette housing 6 is made to extend behind a backrest arrangement of a rear seat bench in the vehicle transverse direction and is held fixed to the vehicle at a spacing below a lateral trim of the motor vehicle 1. In the extended covering state, the covering arrangement that can be stowed in the cassette housing 6 forms an intermediate floor according to FIG. 1, which is arranged below a lateral trim delimited by lower edge regions of the side windows but above a loading-space floor. The cassette housing 6 is fastened detachably in the loading space 2 in order to be able to remove the cassette housing 6 including the covering arrangement from the vehicle as required. The cassette housing 6 has a passage slot which faces the vehicle rear in the installed state, extends in the vehicle transverse direction over at least predominantly the entire width of the cassette housing 6, and is aligned in line with the lateral guides 5 in the oppositely situated side walls of the loading space 2.

[0046] In the present exemplary embodiment, the slats 7 are formed by dimensionally stable hollow profiles of a light metal alloy, in the present case an aluminum alloy, which extend in the manner of strips over an entire width of the loading space 2 in the vehicle transverse direction. Each slat 7 is provided at the front with an upwardly facing hook profile 12 and at the rear with a complementary, downwardly directed hook profile 11, wherein a respective front hook profile 12 in the extended covering state of the slats 7 engages in a form-fitting manner in a downwardly protruding, rear hook profile 11 of the adjacent slat 7—as viewed in the extension direction. In the compactly stowed inactive state, the slats 7 are stowed in a manner stacked one on top of another in the receiving space 9 of the cassette housing 6. A support spring, which in the present case is designed as a conically configured helical spring 10 (FIG. 3), constitutes a compression spring which is supported on a floor of the receiving space 9 of the cassette housing 6 and supports the respectively lowermost slat 7 with its upper face end. On account of the conical helical configuration, in the compressed state the helical spring 10 can be compressed to the height of approximately a single helical winding. The rest of the helical windings lie in a spiral-shaped manner in the same plane within this lowermost helical winding, which is the largest in terms of diameter.

[0047] The slats 7 are connected to one another using connecting straps 10, wherein a plurality of connecting straps 10 connect two respective slats 7 to one another. The connecting straps 10 extend in the extension direction and are designed as flat textile straps. Each connecting strap has a respective welt 13, which engages in a form-fitting manner in a welt groove 14 extending in the longitudinal direction of the respective slat 7, on its oppositely situated face-end regions, accordingly at the front and rear in the mounted state. Each welt groove 14 is open in relation to a bottom side of the respective slat 7 so as to form an undercut, with the result that the associated welt 13 of the respective connecting strap 10 is held in the respective welt groove 14 in a form-fitting manner downwardly in the vehicle height direction. Each slat 7 has two welt grooves 14, which are spaced apart parallel to one another and constitute the mating profiles in the context of the invention, in the region of its bottom side. The welts 13 of the connecting straps 10 form complementary profiles to these mating profiles. The welts 13 of the connecting straps 10 can be pushed in in the longitudinal direction of the slats 7 for mounting from an open end face of the respective welt groove 14. As can be clearly seen on the basis of FIGS. 6 to 11, each slat 7 has two welt grooves 14, a first of which is arranged in a front region and a second of which is arranged in a center region of the bottom side of the slat 7. The welt grooves 14 are conjointly shaped in one piece when the hollow profile of the slats 7 is being produced. The front welt groove 14—as viewed in the extension direction—serves to receive a rear welt 13 of a connecting strap 10, while the center welt groove 14 is provided to receive a front welt 13 of a connecting strap 10 that is adjacent to the rear side. It can be seen on the basis of FIGS. 8 to 11 that, in the state in which the slats 7 are stacked one on top of another, the connecting straps 10 are folded upwardly and rearwardly and accordingly lie between the slats 7 which are respectively adjacent one above another. The connecting straps 10 are tensioned both in the inactive state of the slats 7, in which they are stacked one on top of another, and in the extended covering state, as can be gathered from the illustrations. The tensioned or stretched position of the connecting straps 10 in the different end positions, i.e. the inactive state on the one hand and the covering state on the other hand, is selected, however, such that a small amount of play remains, in order that a jamming or wedging of the adjacent slats 7 relative to one another is not brought about.

[0048] A slat 7 which is at the front in the extension direction is provided with a grip element 8, in order to allow a manual extension or retraction of the slats between the covering position and the inactive position.

[0049] In order that an inclination or wedging of the slats in the mutually opposite lateral guides 5 is not brought about during a corresponding manual extending operation, assigned to the covering arrangement is a synchronizing device, which comprises a synchronizing shaft provided with two toothed pinions 17 at oppositely situated face-end regions. The synchronizing shaft extends in the vehicle transverse direction inside the cassette housing 6 and is mounted in a freely rotatable manner in the cassette housing 6. The toothed pinions 17 (FIG. 13) at oppositely situated face-end regions of this synchronizing shaft mesh with toothing portions 16, which extend along the respective lateral guide 5, in the region of side parts 15 of the slats 7, wherein the linear toothing portions 16 (toothed-rack portions) face downward. The toothing portions 16 are arranged on side parts 15 which are fastened to oppositely situated end faces of each slat 7. When the slats 7 are extended along the lateral guide 5, the toothing portions 16 come into contact with the respective toothed pinion 17 from above. The synchronizing device may at the same time be assigned a drive device, which can drive the slats 7 both in the extension direction and in the retraction direction by way of the toothing portions 16 and the toothed pinions 17. Such a drive is configured analogously to WO 2018/156921 A1.

[0050] The side parts 15 additionally have drivers 18 on the one hand and driver profiles 19 on the other hand, wherein a respective driver 18 of a slat permanently engages in a driver profile 19, lying therebeneath, of a side part 15 of the slat 7 arranged adjacently below, specifically as long as the slats 7 are located in their inactive state, in which they are stacked one on top of another, within the receiving space 9 of the cassette housing 6, and also when the slats 7 are transferred into the extended covering state.

[0051] As can be seen on the basis of FIGS. 14 to 19, the driver profiles 19 are configured as longitudinal grooves that are open outwardly and obliquely downwardly at the front and rearwardly. Each side part 15 has a respective driver 18 on a rear, lower end region of the respective side part 15. Each driver profile 19 has a linear portion which extends parallel to a top side of the respective slat 7, and a further linear portion which is angled away therefrom and extends in an inclined manner to the front and downwardly, wherein the linear portions of a respective side part 15 transition into one another in an open manner. In the state in which the slats are stacked one on top of another, a respective driver 18 of the slat 7 lying above a given slat is positioned at the rear in the upper linear portion of the driver profile 19 of the slat 7 lying beneath that given slat. Each driver 18 is designed as a cylindrical journal, with the result that each driver 18 is mounted not only in a longitudinally movable manner in the driver profile 19 of the slat 7 lying beneath a given slat, but also in a rotationally movable manner in this driver profile 19.

[0052] As soon as the frontmost slat 7, which is provided with the grip element 8 and also in the inactive position is positioned in the passage slot of the cassette housing 6 at the height of the lateral guide 5, is extended by hand away from the cassette housing 6 in the extension direction, the driver 18 on each side, i.e. the two drivers 18 on the oppositely situated side parts 15 of this slat 7, entrains the following slat 7. This following slat is already aligned obliquely upwardly on account of the positioning of the frontmost slat 7 and, when the frontmost slat 7 is subjected to tensile loading, is moved in the extension direction via the toothed pinion 17 and guided necessarily into the lateral guides 5 by virtue of the corresponding tensile loading. During this movement, the drivers 18 of this second slat 7 run in the driver profiles 19 of the third slat 7, which is still stacked in the receiving space 9. As soon as the driver 18 arrives in the portions of the driver profiles 19 that are inclined downwardly to the front, this slat 7 is necessarily raised obliquely upward and likewise drawn out toward the toothed pinions 17 and the lateral guides 5. This mode of operation continues until the covering arrangement composed of the multiplicity of slats 7 that are joined to one another has reached the extended covering position. A retraction is effected correspondingly in reverse by manually applying compressive loading to the frontmost slat, as a result of which the rest of the slats 7 are pushed in the direction of the passage slot of the cassette housing 6 and necessarily stack one on top of another again in the receiving space 9. The drivers 18 remain permanently in the driver profiles 19 of the respectively following slat 7.

[0053] A covering apparatus according to FIGS. 20 to 22 corresponds largely to the covering apparatus according to FIGS. 1 to 19 described above. To avoid repetitions, reference is therefore additionally made to the embodiments relating to the covering apparatus according to FIGS. 1 to 19. Components or portions with the same function are provided with the same reference signs, but with the addition of a prime ′. The differences of the covering apparatus according to FIGS. 20 to 22 are addressed below.

[0054] The covering apparatus according to FIGS. 20 to 22 has a multiplicity of dimensionally stable slats 7′, to which a respective side part 15′ is assigned on mutually opposite end faces. A slat which is at the front in the extension direction and thus in the direction of the extended functional position is provided with a grip element 8′, which allows the slat composite to be manually gripped. A significant difference to the covering apparatus according to FIGS. 1 to 19 is that the slat composite composed of the multiplicity of slats 7′ arranged one behind another is connected together via two connecting straps 10′ which are parallel to one another, wherein each connecting strap 10′ extends over the entire length of all of the slats 7′ and thus over the entire length of the slat composite. Each connecting strap 10′ is accordingly connected to all of the slats 7′ of the slat composite. The connection of the connecting straps 10′ to the slats 7′ is effected via mechanical connecting means in the form of rivet connections 20, which can be seen on the basis of FIGS. 20 to 22. The connecting straps 10′ extend parallel next to one another over the length of the slat composite and have a relatively large width which extends approximately over a range between a quarter and a third of the width of the slats 7′. The two connecting straps 10′ adjoin the side parts 15′ directly on the outside and extend with their width transversely to the extension direction toward the center. In the extended functional position of the slat composite, the two connecting straps 10′ are aligned on the bottom side of the slat composite in a planar and stretched manner. In the inactive position of the slat composite, in which the slats 7′ are arranged stacked one on top of another in the receiving space 9′ of the cassette housing 6′, the respective connecting strap 10′ is necessarily folded, as can be seen in FIG. 22. As FIG. 21 shows, the mechanical connecting means, in the present case the rivet or screw connections 20, are positioned in a front half of the respective slat 7′ in such a way that a sufficiently long, loose connecting strap portion is produced between two respective slats 7′ that makes the corresponding folding possible.
