    Agricultural transport wagon
    The present invention relates to an agricultural transport truck, in particular in the form of a loading and / or forklift truck, with a loading space bounded by a loading space floor and upright loading space walls, wherein at least one of the loading space walls is of multi-part design and an underlying base part as well as at least one upper hinge part, which can be pivoted about a lying hinge axis with respect to the base part, and with a cover device for covering the load space from above, the cover device comprising at least one cover member which a displacement mechanism selectively between a clamping position, in which the cover member is at least partially stretched over the loading space, and a storage position, in which the cover member is stored on one side of the loading space and releases the top of the loading space, can be moved back and forth.
    With loading or forklifts, in particular with street transport, when driving faster, food loss due to wind may occur, which sweeps from above through the loading space and can raise feed or forage material located there. To prevent this, the top of the loading space can be covered with a suitable covering device, for example in the form of a tarpaulin stretched over the top of the loading space, a clamping net or a clamping grid, for example in the form of an elastic net, but also in the shape of an at least partially stable roof element, which can be stretched over the top of the loading space in the manner of a convertible roof and can be stored on one side of the loading space to release the top. The latter can be applied, for example, when the loading space is filled from above by means of a forage wagon, as is the case, for example, with the maize harvest. Apart from wind and wind problems, covering devices, for example in the form of watertight or water-draining cover plates, are also used to protect the crop from rain during transport.
    Covering devices for loading wagons and forklifts are known, for example, from the patent publications DE 20 2006 017 787 U1, DE 20 2009 014 277 U1, De 20 2008 014 981 U1 or DE 10 2005 049 125 B4.
    In the case of loading and chopping wagons which have a multi-part front wall, the upper part of which is in the form of one or more hinge parts and which can be folded away for chopping, such cover devices which can be folded out over the top are not very simple to implement, since dependent from the position of the upper hinge part the multi-part load space wall can collide with the cover device, or the hinge part cannot be moved in the desired manner when the cover device is suspended in the clamping position on the upper edge of the hinge part. When the clamping device is tensioned and suspended from the upper edge of the hinge part, the hinge part cannot simply be folded away. If the cover device is stable enough, then the hinge part drive is overloaded, on the other hand the hinge part drive is too strong, then the cover member will tear if it is designed, for example, in the form of a very thin cover sheet.
    This problem is exacerbated when said multi-part load space wall comprises a plurality of switched, hingedly connected hinge parts, a first hinge part of which already extends to the top of the load space and the load space is limited above the base part of the load space wall, and the second hinge part is provided to protrude into the loading space at an angle with the vertical and to limit it upwards, in order to be able to give more counter-pressure or to operate the scraper floor when the feed stock builds upwards. With such a multi-part load space wall, if the said second hinge part is hinged too far upwards, when the cover device is stretched over the load space, the second hinge part collides with the cover member, which can lead to damage to said cover member or the hinge mechanism.
    Patent publication DE 20 2006 017 787 U1 shows, for a loading wagon whose front cargo space wall is foldable, a covering device which comprises a winding drum for the tarpaulin suspended from the hinge part. The winding drum is pre-tensioned here with a spring device which can be deactivated by a retractable pawl to prevent unwinding under spring force as required. In use, the tarpaulin will be manually hung on a hook at the rear end of the cargo space on an upper part or, conversely, will be suspended by hand when the tarpaulin is rolled up and the hinge part of the front cargo space wall is pivoted forward into the insertion position. Doing this manually by hanging out is difficult and moreover requires an exit from the tractor driver each time. In addition, activating or deactivating the spring preload of the winding drum as required is prone to incorrect operation. In addition, the device with the winding drum on the hinge part of the front cargo space wall is also unfavorable for folding up said hinge part, since the joint weight of the winding drum and the cover sheet wound on it loads the hinge part, which is particularly important when the insert position is folded forward and corresponding lever arm loads the drive of the hinge part.
    The present invention has for its object to provide an improved agricultural transport vehicle of the type mentioned in the preamble, which avoids the disadvantages of the prior art and advantageously broadens them. In particular, an easy-to-operate cover device will be provided which avoids collisions with the hinge part of the multi-part load space wall and prevents incorrect operation and consequent risk of damage as much as possible.
    According to the invention this object is achieved by an agricultural transport vehicle according to claim 1. Preferred embodiments of the invention are the subject of the dependent claims.
    It is proposed to sensitively monitor the position of the cover device and / or the hinge part of the multi-part load space wall and to control the activation of the displacement drive of the cover device in dependence on the position of the hinge part of the load space wall or vice versa the activation of the control hinge part drive of said hinge part in dependence on the concentrated position of the cover device. In particular, the hinge part drive of the hinge part of the multi-part load space wall is only released when the cover device is in a non-impact sensitive position. According to the invention, the cover device is provided with at least a first detection device for detecting the position of the cover device and / or the displacement mechanism of the cover device. A release device switches the hinge part drive of the hinge part in dependence on a releases signal from the detection device when the cover member is in its storage position, and / or blocks the hinge part drive when the cover member is in its tensioning position. As a result, damage to the cover member, but also overloading of the hinge part drive can be overcome. Incorrect operation is automatically avoided.
    In a further embodiment according to the invention, the hinge part of the multi-part load space wall and / or its hinge part drive can be provided with at least a second detection device for detecting the position of the hinge part, wherein a second release device for releasing / blocking is advantageously is provided with the displacement mechanism of the covering device. Said second release device can then release the displacement mechanism of the cover device in dependence on a signal from said second detection device, in particular when the hinge part is in its raised position, and / or then block the displacement mechanism when the hinge part is not in its final transport position and / or is in a pushed forward position and / or is in a loading position projecting obliquely into the loading space. Releasing or blocking the cover device in dependence on the detected position of the hinge part can prevent the cover device from being closed without the hinge part of the multi-part load compartment wall being in the position suitable for this purpose.
    In an advantageous further embodiment of the invention, the control of the hinge part and / or the displacement mechanism of the cover device can release or block more than just one and, in addition, it can provide for coordinating the displacement movement in dependence on the detected position of the cover member and / or the hinge part. In particular, the control can permit a certain movement as long as there is no danger of collision, or cause or interrupt it as required, until the other component has reached the desired position. In a further embodiment of the invention, the hinge part drive of the hinge part can be provided with a control device which, in dependence on a signal from the first detection device assigned to the cover device, controls said hinge part drive such that when the cover member is moved out of its storage position the hinge part of the multi-part load compartment wall is automatically brought into its raised position, in which the cover member of the cover device can be moved into its clamping position without risk of collision or in accordance with the regulations.
    Alternatively or in addition to such an automatic activation of the hinge part, the said control device can also delay or interrupt the displacement mechanism of the clamping device, until the hinge part in the given case has been brought into a necessary transport position by a manual displacement movement. In a further embodiment of the invention, said control device advantageously comprises control means for delaying and / or controlling and / or interrupting the displacement mechanism of the cover device in dependence on a signal from the second detection device such that the cover member only then fully when the hinge part of the multi-part load compartment wall is in its upright transport position. A movement of the clamping device from its storage position can in any case be permitted here, even when the hinge part is not yet in its intended transport position. As a result, the displacement times can be connected in parallel and the full time for the clamping operation can be shortened. The control means mentioned ensure that the clamping device is brought into the clamping position sufficiently slowly, in a given case with necessary interruption, so that before the clamping device reaches the fully tensioned position, the hinge part is brought into the cooperating position with it.
    The first and / or second detection device can be of substantially different designs, in particular different sensors, which can detect the position of the cover device or the hinge part in different ways. For example, optical or tactile sensors can be used, but other sensor principles can also be used.
    In an advantageous further embodiment of the invention, the first detection device for detecting the position of the covering device and for detecting the clamping position can be provided in an area of the first hinge part or the wall sensor of the load compartment wall adjacent thereto which comprise the clamping sensor arranged thereon cover member in the tensioning position detects or detects when said cover member reaches the full tensioned position. Alternatively or additionally, the first detection device may comprise a storage position sensor which is provided for detecting the cover member in the storage position and detects the cover member and / or the displacement mechanism when the cover member has reached the full storage position. Alternatively or additionally to end position sensors which detect the relevant end position of the cover member, at least one further sensor can also be provided which continuously or stepwise detects the displacement movement of the cover member between the two end positions such that the control device for the displacement drive of the cover device and / or for the hinge part drive of the hinge part continuously or stepwise detects where the cover device is located or in which intermediate position the cover device is located.
    In a further embodiment according to the invention, the aforementioned second detection device which detects the position of the at least one hinge part of the multi-part load space wall may comprise a transport position sensor which detects the hinge part in its transport position and / or insert position sensor comprising the hinge part detects in the insertion position and / or comprises a loading position sensor which detects the hinge part in the loading position. Alternatively or additionally, here too at least one sensor can be provided which continuously or stepwise detects the position of the hinge part, so that the connected control device knows continuously or stepwise what position the hinge part is in.
    The covering device can be held in its stretched position essentially in various ways, for example in that the associated displacement mechanism is braked or locked in the stretched position or is otherwise blocked. Alternatively or additionally, it may also be provided that the cover device in the stretched position is connected to the at least one hinge part of the multi-part load space wall. To this end, in a further embodiment according to the invention, detachable connecting means can be provided with which the cover device can be detachably connected to the said hinge part. Such releasable connecting means can be designed in various ways, wherein, for example, clamping means for clamping the cover device to the hinge part or form-retaining means can be provided, for example in the form of suspension hooks, with which the cover member can be hung on the hinge part. The connecting means are herein advantageously provided with a displacement actuator driven by external energy, in order to be able to release and close the connecting means with external energy, for example that the suspension hooks can be hooked in and out or clamping claws can be brought together or apart.
    In an advantageous further embodiment according to the invention, the cover device can be clamped in the tensioned position. This is in particular advantageous when a bend slab or an elastically flexible cover member, for example in the form of a cover or a cover net, is used. In a further embodiment according to the invention, the displacement mechanism for displacing the cover device can comprise a tensioning device for tensioning the cover member, wherein said tensioning device is advantageously designed so that it can be controlled in dependence on a signal from the aforementioned first detection device. that after reaching the clamping position the clamping device is activated and the cover member is clamped by a feed device reversing the displacement mechanism. Alternatively or additionally, said clamping device can be controlled such that the clamping device is deactivated before the displacement mechanism moves the cover device back from its clamping position to the storage position.
    In a further embodiment according to the invention, the covering device can be provided with a winding drum for winding up the covering member on a loading space wall opposite the hinge part of the multi-part loading space wall. The cover member can be wound up on said wrapping drum to be stored. If the above-mentioned manner and clamping device are provided, it can act on the winding drum and, when the cover member is fully tensioned or is suspended or fixed in the aforementioned manner on the hinge part of the multi-part load compartment wall, by turning back the winding drum.
    The invention will be explained in more detail below with reference to a preferred embodiment and associated drawing. In the drawing: Fig. 1: shows a schematic side view of a preferred embodiment of a loading and chopping wagon for bringing in crop material according to the invention, wherein the loading and chopping wagon is connected to a tug by means of a drawbar, Fig. 2: a perspective view partial representation of the front, upper part of the loading space of the loading wagon of fig. 1, in which two upper hinge parts of the front loading space wall are shown in its loading wagon position, fig. 3: an illustration of the front, upper part of the loading space according to fig. 1, in which both hinge parts of the front cargo space wall are shown in their filling rack for lateral loading of chopped goods, FIG. 4: an image of the cargo space according to FIGS. 2 and 3, the two hinge parts of the front cargo space wall lowered in their forward position insertion position are shown, and fig. 5: a partial side view of the loading wagon according to fig. 1, which shows the cover device for the top of shows the cargo hold in various fixtures, storage and intermediate racks.
    The loading and unloading wagon 1 shown in Figure 1 is designed as a trailer tool in a manner known per se and comprises a chassis 2 which carries a machine frame 3 which is coupled to a tractor 5 by means of a drawbar 4. Provided on the machine frame 3 is a cargo space 6 which is bounded at the bottom by a cargo space floor and on the side, front and rear by cargo space walls 8, 9, 10 and 11, which extend substantially perpendicularly from the edges of said cargo space bottom 7. The top of the loading space 6 is substantially open, but can be covered with a cover device 40 that can be extended from behind, as will be explained in more detail below.
    In a manner known per se, a pick-up conveyor 12 is provided in the part of the front end of the loading space 6, which pick-up comprises a liftable and lowerable pick-up, with which crop material lying on the ground such as hay and grass can be taken from the ground and into the bottom from below. front end of the loading space 6 can be entered.
    The rear cargo space wall 11 can be designed in a manner known per se as a folding rear door, in order to be able to empty the cargo space 6. Provided in the loading space 6 is a scraper floor, not known per se, with which the feed stock present in the loading space 6 can be transported backwards to the rear end of the loading space 6.
    The front cargo space wall 10 is of multi-part design in the manner shown in Figs. 2 to 4. A rigid base part 13 which, in the manner shown, forms approximately the lower half or the lower two-thirds of the front cargo space wall 10 is rigidly connected to the cargo space walls 8 and 9 on the side. A first hinge part 14 is hingedly connected to the top of the base part 11 about a horizontal transverse axis 15, which is thereby pivotable relative to the base part 13. A second hinge part 16 is hingedly connected to said first hinge part 14 about a horizontal transverse axis 17. The second hinge part 16 is hingedly connected to the side of the first hinge part 14 remote from the base part 13, in such a way that the second hinge part 16 can be folded onto the inside of the first hinge part 14. The two hinge parts 14 and 16 are each plate-shaped or wall-shaped and, depending on their position, form a continuation of the load compartment wall part formed by base part 13. In the exemplary embodiment shown, the two hinge parts 14 and 16 are then substantially of comparable dimensions, wherein they are clearly smaller than base part 13. Each of the hinge parts 14 has a height that is roughly one fourth of the total height of the loading space 6.
    As Fig. 2 shows, displacement drives 18 and 19 in the form of hydraulic cylinders 20 and 21 are provided for hinging the two hinge parts 14 and 16. A first hydraulic cylinder is thereby connected at its lower end to a pivot point 22 fixedly connected to the base part and connected at its upper end to the first hinge part 14, in particular to a lever connected thereto. In figure 2 only one hydraulic cylinder is shown, it will be clear that a pair of such first hydraulic cylinders 20 are provided on the right and left at the said suspension points. Alternatively, however, a centrally placed cylinder can also be provided.
    A second hydraulic cylinder 21 is on the one hand pivotally suspended on the first hinge part 14, in particular in the part of the transverse axis 15, around which the first hinge part 14 is pivotable. On the other hand, the second hydraulic cylinder 21 is hinged to the second hinge part 16, in particular to a lifting arm 23 connected thereto, in order to be able to pivot the second hinge part 17 relative to the first hinge part 14. As Fig. 2 shows, said lever arm 23 is thereby staggered, so that it extends in the shape of an arc over the top of the first hinge part 14. Accordingly, the second hinge part 16 can be effortlessly moved back and forth between the position shown in Figure 2, which protrudes from the first hinge part 14 inwardly into the loading space 2, and the position shown in Figure 4, which is folded onto the inside of the first hinge part 14. moved. Advantageously, the pivot axis 17, why the second hinge part 16 can be tilted, is provided somewhat on the inward side of the top of the first hinge part 14, in order to enable the second hinge part 16 to be able to fold substantially completely on the inside of the first hinge part 14. , see figure 4.
    It will be clear that also for the second hinge part 16 on the left and right a pair of such second hydraulic cylinders 21 can be provided, also when figure 2 shows only one.
    Hydraulic cylinders 20 and 21 can be actuated independently of each other. A control device 24, only schematically indicated, which can be formed by a work computer arranged on the loading and forklift truck 1 and / or by a control device on the tractor side, controls for this purpose the hydraulic device of the hydraulic cylinders 20 and 21.
    As a result, the two hinge parts 14 and 16 can be brought in three different configurations, as is shown in figures 2 to 4. In the loading-carriage position shown in Figure 2, the first hinge part 14 is rotated in an upright position above the base part 13, which can be effected by sliding out the first hydraulic cylinder 20. At the top of the first hinge part 14, stops 25 can be provided which hold the first hinge part 14 on the side in a defined position with respect to the cargo space walls 8 and 9. On the other hand, the hydraulic cylinders 21 are used to bring the second hinge part into an inward position protruding into the loading space at an acute angle with respect to the first hinge part 14, as shown in Figure 2. In the embodiment shown, the second hinge part extends - roughly - approximately perpendicular to the rear in the loading space 6, so that the second hinge part 16 assumes a horizontal position and limits the loading space 6 upwards at its front end. In this position of the two hinge parts 14 and 16, the loading and chopping wagon 1 can operate in accordance with a normal loading wagon. The second hinge part 16 herein functions as a compacting valve which compacts the harvested material introduced into the loading space by the pick-up conveyor 12 when it stacks upwards on the front loading space wall 10, more precisely the inside thereof.
    In order to be able to better feed chopped goods into the loading space 6 from above, the second hinge part 16 is folded away, so as not to obstruct the insertion from above. Such a filling position is shown in Figure 3, in which the first hinge part 14 is in the upwardly rotated position, while the second hinge part 16 is folded on the inside of the first hinge part 14 by extending the second hydraulic cylinders 21, so that the second hinge part 16 extends substantially parallel to the first hinge part 14 on its inside. This position is optimal for the lateral introduction of forage material when, for example, the loading wagon rides alongside the forage harvester, so that the forage material is thrown into the loading space 6 substantially over one of the two cargo space walls 8 or 9.
    In order to enable or improve the so-called insertion of the forage material, the two hinge parts 14 and 16 can be lowered towards the outside of the loading space 6, as is shown in figure 4. The second hinge part 16 is in this case in the inside of the first hinge part 14 folded position. The first hinge part 14 is pivoted forward together with the second hinge part 16 folded against it, as shown in figure 4, wherein the first hydraulic cylinder 20 is retracted. In this insertion position according to Figure 4, the two hinge parts 14 and 16 extend substantially lying and, broadly speaking, extend perpendicularly to the base part 13. As a result, the chopped goods can be thrown into the loading space 6 in a flat throwing arch over the tractor through the insertion opening 26, by lowering the two hinge parts 14 and 16 in the middle above the base part 13.
    Advantageously, despite the multiple pivotability of the two hinge parts 14 and 16, a loading machine is integrated in the loading and chopping wagon, which transports the harvested goods over the pick-up conveyor 12 into the loading space 6 and in particular by the scraper floor (not shown) in the loading space 6 controls independently, and this depends on the crop mix that builds up on the front loading space wall 10 or the crop load that is created as a result. Advantageously, the crop pressure is caught by the second hinge part 16 when it is in the loading space position according to Figure 2. To this end, the second hinge part 16 in the shown loading wagon position according to Fig. 2 is movable over a limited path despite an immovably switched displacement drive 19, or more precisely hinged. To this end, a releasing means 27 is provided between the displacement drive 19 and the second hinge part 16, which relieves said limited movability. In the embodiment shown, the release means 27 are formed by elongated slots 28, in which the hinge mounting points of the second hydraulic cylinder 21 are guided movably, such that the second hinge part 16 can be hinged slightly upwards from the position shown in Figure 2, without that the hydraulic cylinder 21 undergoes a movement. On the contrary, the loading wagon position of the two hydraulic cylinders 21 is an end position, such that they cannot be retracted at all.
    The movement of the second hinge part 16 made possible by the freewheel means 27 is detected by a movement sensor 29 which, together with the chosen arrangement and embodiment of the second hinge part 16, forms a harvest material pressure detection device 30 and, as shown in Fig. 2, in different positions can be arranged: without counter-pressure, the second hinge part 16 is pulled down by gravity in the starting position shown in Figure 2. If the harvested material is increasingly pressed against the second hinge part 16 from below, it then pivots accordingly upwards. This pivotal movement is detected by the said movement sensor 29, which is connected to the schematically shown control device 24. This comprises a scraper bottom control unit 31 which, depending on the signal from the movement sensor 29, controls the scraper bottom in the interior of the loading space 6. If the second hinge part is pushed upwards along a predetermined path, the scraper bottom is turned on or switched faster, to be transported backwards under the building up feed stock into the loading space 6 and thereby to reduce the pressure on the hinge part 16. It therefore falls back to its lower starting position, which is again detected by motion sensor 29, so that the scraper floor can be switched off or switched more slowly.
    As Fig. 2 shows, for the second hinge part 16 in its loading wagon position a receiving holder 32 is provided, which in the shown embodiment is provided on the inside of the loading space walls 8 and 9 on the side. The collecting container 32 herein comprises a rigidly arranged stop 33 which protrudes inward from said lateral loading space walls 8 and 9 and which is provided approximately in the area of the rear side of the second hinge part 16 in its loading wagon position. However, in the starting position of the second hinge part 6 shown in Figure 2, the latter is not engaged with the stops 33. This only takes place when the resulting crop pressure pushes the second hinge part 16 upwards in cooperation with the aforementioned freewheel means 27. The stop 33 can be designed as a catch hook or can, in kinematic reversal, be provided on the second hinge part 16 as a corresponding catch hook that catches the stop 33. When the second hinge part 16 comes into engagement with the receiving holder 32, the second hinge part 16 is advantageously not only held upwards but also forwards, so that the first hinge part 14 is also secured against being pushed forward. Through this collecting container 32, the entire construction, that is to say the two hinge parts 14 and 16, as well as their displacement drive 18 and 19, can be dimensioned in a small way and therefore be of light design.
    Advantageously, the arrangement of the collecting container 32 is designed in such a way that it can only come into engagement with the second hinge part 16 when the latter hinges upwards from the loading wagon position according to Figure 2 due to the resulting crop pressure. On the other hand, without the harvest pressure, that is, when the second hinge part 16 is in its lower starting position according to Figure 2, if the first hinge part 14 is rotated forward, the second hinge part 16 moves past the receiving container 32. This prevents damage due to incorrect operation.
    As Figure 5 shows, the top of the cargo space 6 is provided with cover device 40 which, depending on the position, the cover releases or closes off the cargo space, the cover device 14 in the tensioned position being able to extend in particular along or adjacent to the upper edges of the cargo space walls 8, 9, 10 and 11.
    Said covering device 40 can herein advantageously comprise a flat covering member 41, for example in the form of a covering sheet, a covering net or a flexible covering grid or covering fabric, which can be wound onto a winding drum 42.
    As Fig. 5 shows, said winding drum 42 can advantageously be provided in the upper part of the rear cargo space wall 11, wherein the drum rotating axis of said winding drum 42 can advantageously extend in horizontal transverse direction parallel to the wheel axles of the chassis. The cover member 41 can be pulled off from said winding drum 42 to be stretched over the top of the loading space 6. For this purpose a displacement mechanism 43 is provided which can be designed in different ways and advantageously comprises an externally driven displacement drive, in order to be able to open and close the cover device 40 by motor.
    The displacement mechanism 43 can herein, as shown in Fig. 5, comprise at least one swiveling arm 44 which is pivotally suspended about the horizontal transverse axis from the body of the loading and unloading wagon 1, for instance in a part between the front loading space wall 10 and the rear loading space wall 11. In the embodiment shown, a single-axis pivotable hinge bracket 44 is provided, which is pivotally suspended in a lower part of the lateral load space walls 8 and 9 about said transverse axis between the front and rear load space walls 10 and 11. Alternatively, however, it is also possible to provide a plurality of hinge brackets which are connected to one another, for example to support the cover member 41 on different sections, as is known with convertible covers of motor vehicles.
    In a further embodiment of the invention, however, an alternative to such a displacement mechanism with hinge brackets can also be provided for clamping the cover member 41 with a slot guide, which can for instance comprise guide rails arranged on the upper edge portion of the lateral load space walls 8 and 9, in which the cover member 41 can be pulled sideways in the direction of the front cargo space wall 10, wherein said slot guide can be provided with a corresponding drive set, for example a traction cable, a spindle drive, or the like.
    The displacement mechanism 43 with hinge bracket 44 shown in Fig. 5, however, is distinguished by a simple design and moreover has the advantage that during its clamping movement the cover member 41 is stretched forward in a arch which is raised over the loading space walls 1 so that even with fully filled If necessary, filling positions protruding above the upper loading space sides, the cover member 41 can be tensioned without difficulty. Even when the food supply in the loading space protrudes above the upper loading space sides, the tarpaulin can be stretched out without collision and stored in reverse.
    As Fig. 5 shows, the cover member 41 is advantageously provided with a detection device 45, which detects the position of the cover member 41. Said detection device 45 may in a further embodiment according to the invention comprise a position-out sensor 46, which can advantageously be provided in the front, upper edge areas of the lateral cargo space walls 98, in order to be able to detect the cover member 41 when it is located in moves its fully stretched position, i.e. approaches the top of said first hinge part 14, when the latter is in the transport position shown in Figures 2 and 3.
    Alternatively or additionally, said detection device 45 may comprise a storage position sensor 47, which is advantageously provided at a rear upper area of the lateral cargo space walls 8 and 9, or also provided at the rear cargo space wall 11 itself, to detect when it cover member 41 is in the storage position. For example, said storage position sensor 47 can detect a front side of the cover member 41 as it approaches the winding drum 42. For example, a marking or a marking element, for example in the form of a magnetically detectable rod or the like, can be provided here at the front edge portion of the cover member 41.
    The control device 24 assigned to the hinge part drives 18 and 19 is connected to the said detection device 45 and provides control of the hinge parts 18 and 19 depending on the position of the cover device 40. In particular, the said control device 24 include release device 48 which blocks or does not release hinge-part drive 18 and 19 or does not keep it energized when the cover member 41 is in the fully extended position.
    Alternatively or additionally, said control device 24 may also comprise a release device 49 which blocks the displacement drive of the displacement mechanism 43 of the cover device 40 or keeps it inactivable or does not release than when the first and a second hinge part 14 or 16 are not in front of it. the position of the hinge parts 14 and 16 is monitored by a second detection device 50, which can be formed by the above-mentioned movement sensors 29.
