Description

[0001] The invention relates to a load compartment cover for a motor vehicle according to the preamble of patent claim 1. Furthermore, the invention relates to a method for operating such a load compartment cover.

[0002] Load compartment covers for vehicles that separate the cargo area or protect cargo are available in various designs. Roller covers are often used, which are easy to retract and extend. However, this poses a problem when comfort seats are installed in the rear, as there is no continuous rear seat bench to which the roller cover could be attached. These comfort seats require more space and freedom of movement, which can impair the function of the roller covers.

[0003] DE 203 19 225 U1 already discloses a vehicle with a spacious rear cover formed by several similarly shaped slats that are arranged adjacent to one another along their longitudinal sides and partially overlap. The individual slats are pivotally mounted at their ends on a common horizontal axis, and each slat forms a semicircle from this pivot point. Each slat widens in width from the narrow end area supported on the axis to the center of the slat to cover a shell-shaped partial surface.

[0004] Furthermore, DE 102 15 966 ​​B4 discloses an opening vehicle roof comprising a composite of several extendable slats arranged one behind the other in the vehicle's longitudinal direction, which lie flat against one another in a closed position. The slats can be slid parallel to one another in a package-like manner to at least partially expose the roof opening.

[0005] In addition, DE 89 08 186 U1 discloses a vehicle with a side opening which consists on both sides of a door flank segment designed as a hollow body and open upwards, a glazing element and a roof segment, all three of which are guided around the interior cross-section in the front and rear areas on a roll bar each so as to be radially displaceable upwards and downwards in the vehicle's longitudinal axis.

[0006] Another example is JP H 05 246 351 A, which discloses a vehicle with a hood. The hood consists of three U-shaped segments that can be telescoped into one another in the longitudinal direction of the vehicle.

[0007] The object of the invention is to provide a load compartment cover which is particularly easy to operate and saves costs and space, particularly when comfort seats or vehicle seats are arranged in the rear area of ​​the motor vehicle.

[0008] This object is achieved by means of a load compartment cover having the features of patent claim 1 and by means of a method according to the invention. Advantageous embodiments of the invention are the subject of the dependent patent claims and the description.

[0009] A first aspect of the invention relates to a load compartment cover for a motor vehicle, in particular for a passenger car, comprising two louvre devices arranged opposite one another in the transverse direction of the vehicle and in a load compartment of the motor vehicle. Accordingly, two louvre devices arranged opposite one another or standing opposite one another are provided, a distinction being made here between a first louvre device and a second louvre device. Each of these louvre devices comprises a plurality of louvres rotatably connected to a respective axis of rotation, each louvre of the first louvre device being connected to a corresponding louvre of the second louvre device via a respective transverse element.

[0010] In this context, "corresponding slats" mean that the slats of the two slatted devices are coordinated in their arrangement and size. This means that each slat of the first slatted device exactly matches a slat of the second slatted device, for example, in size or sequence. As a result, the slats of both devices are arranged essentially identically, so that they run parallel to each other and are each connected by a cross element. This ensures a smooth and synchronous movement of the slats when the load compartment cover is in use.

[0011] The connection is made via the respective cross element, whereby one slat, together with a corresponding slat of the opposite slat arrangement, forms an arched structure. This means that each slat of the first slat arrangement is connected to a corresponding slat of the second slat arrangement by the cross element. Together, these slat pairs form a cover in the shape of an arched structure. A decreasing size arrangement of the slats is maintained, whereby the arched structure is stepped and runs in decreasing size. In other words, a decreasing size arrangement is provided for the arched structures.

[0012] In this case, it is provided that the slat devices are adjustable between a rest position, in which the respective arched structures are moved together and, due to the decreasing size arrangement, an arched structure always essentially surrounds the next smaller one on the outer circumference, and a use position, in which the respective arched structures are pivoted relative to the respective axes of rotation and the respective transverse elements thus at least partially cover the loading space, with a largest arched structure covering a longest pivoting path. In other words, it is provided that the slat devices are adjustable between two positions: the rest position and the use position. In the rest position, the slats and thus also the arched structures are pushed together in such a way that, due to the decreasing size arrangement, each smaller slat / arched structure is essentially enclosed on the outer circumference by the next larger slat / arched structure.In the use position, however, the slats are rotated around their respective axes of rotation, so that the cross elements and thus also the arched structures at least partially cover the cargo area. The largest arched structure travels the longest pivoting distance. The arched structures can thus be adjusted so that they are nested in the rest position and partially cover the cargo area in the use position, for example, to load a luggage compartment.

[0013] In other words, this means that the slat devices can be adjusted between the rest position and the use position. In the rest position, the slats and therefore also the load compartment cover should essentially be brought together so that they do not cover or separate the load compartment or restrict its volume. In the use position, the slat devices are intended to be operated and thus at least partially separate the load compartment or the load compartment cover is used. Since the respective slat devices are designed in particular as a type of fan system, they can be moved apart. By moving the respective slats apart and connecting them to the cross elements, the arched structures are moved apart. These form a covering surface with the cross elements that extends into the load compartment.

[0014] To provide the rest position, an exemplary embodiment includes three arched structures that can be adjusted around the same axes of rotation - the outermost arched structure, the middle arched structure, and the innermost arched structure. The outermost arched structure is the largest, the middle arched structure is smaller than the outermost arched structure, and the innermost arched structure is the smallest. This descending order of size ensures that no collisions occur between the respective arched structures when they are adjusted back. Accordingly, it is also intended that the largest arched structure also travels the longest pivot path when it is pivoted into the use position. This also applies to the other smaller arched structures in decreasing order of size.

[0015] In summary, the descending size arrangement of the arch structures ensures that they slide into each other in the resting position to save space without colliding.

[0016] In an advantageous embodiment of the invention, the cross elements are flat and angled in such a way that they form a continuous, particularly flat surface relative to one another in the use position. This means that the cross elements are not round or otherwise, but are actually just flat, and the respective flat surface of the respective cross elements, which in the rest position are oriented upwards in the vertical direction of the vehicle, together with the other cross elements and their respective surfaces form the continuous surface. A particularly flat, continuous surface is thus represented by the respective individual cross elements. The flat surfaces of the cross elements thus enable even support, so that together they form a stable and visually appealing surface that serves to protect or cover the cargo space or can be seen / used as a classic parcel shelf.This design offers the advantage of eliminating gaps or unevenness, which not only improves the appearance / design but also functionality. For example, objects can be placed on this surface without slipping or getting caught in gaps.

[0017] For example, a transition element directed towards one another can be arranged or integrated at the edges of the cross elements. This transition element is particularly tapered and made of rubber or plastic, particularly an elastic material, to enable the cross elements to fit snugly against one another. This tapering ensures that the cross elements rest neatly on one another and creates a stable connection. This prevents gaps or uneven transitions between the cross elements, improving the stability of the surface and creating a uniform surface. In particular, this enables a modular formation of the continuous surface.

[0018] It is also possible for the cross elements not to be rigidly arranged on the slats, but to be partially adjustable, for example via their own pivot axes, such as hinge elements. This offers the advantage that when the height of a slat device is adjusted, the cross elements can also be adjusted. Adjusting the height of a slat, for example, could tilt the surface. Depending on the design, the cross elements could also be telescopically extendable and adjusted across the cargo area. Alternatively, a slat device can be both height-adjustable and movable across the vehicle, making it easier to insert special items into the cargo area.In this way, the slatted devices can be flexibly adapted to the shape and size of the load, which also makes it possible to provide not only a continuous surface but also an adjustable, adaptable surface.

[0019] In another advantageous embodiment of the invention, the rotational axis of the respective slat devices is arranged in a load compartment floor and / or at the front in the vehicle's longitudinal direction. This means that the slat devices are positioned in front of the load compartment in the vehicle's longitudinal direction, particularly in the lower area. When the slats are pivoted rearward about the rotational axis, a continuous surface is created that extends from front to rear. This arrangement makes it possible to position / place the slat devices as far forward as possible, directly behind a comfortable seat in the rear, so that conventional roller blinds can be replaced while still largely covering the entire load compartment.

[0020] In a further advantageous embodiment of the invention, it is provided that the slat devices are translationally adjustable along the cargo space. In this case, it is possible, for example, for the slat devices to be moved rearward, in particular in the longitudinal direction of the vehicle, using adjustment devices such as rail elements or actuators. This allows the slat devices to also be moved rearward when the comfort seat in the rear area is adjusted, so that the slats are pivoted rearward in the longitudinal direction of the vehicle from this new position. Furthermore, it is also possible to adjust the height of the slat devices, i.e., up or down in the vertical direction of the vehicle, in order to adapt them to different situations in the cargo space.This could be useful, for example, if larger objects need to be loaded into the cargo area, so the slats are adjusted upwards to create more space. Alternatively, the slats themselves could be telescopically extended in the vehicle's longitudinal direction, or the rotation axis could be adjusted to flexibly respond to different loads / objects. By being able to adjust both longitudinally (forward or backward) and vertically (up or down), this solution offers a high degree of flexibility, allowing the load compartment cover to be optimally adapted to the loaded loads / objects or to cover them.

[0021] The load compartment cover can be designed to detect a signal when the comfort seat is adjusted and automatically adjust accordingly. When the comfort seat is adjusted, the load compartment cover is moved synchronously into the required position to ensure secure coverage of the load compartment. The same applies to opening the load compartment: as soon as the load compartment is opened, the load compartment cover can automatically move to a predetermined position. In addition, the load compartment cover can be equipped with sensors that detect whether there are any cargo / objects on the cover surface or whether a collision is imminent when the tailgate is closed or the comfort seat is adjusted. In such cases, the cover could move independently to a safe position or generate warning signals to prevent damage and ensure smooth adjustment.

[0022] In another advantageous embodiment of the invention, the respective transverse elements are formed in two parts, consisting of two separable transverse element parts. Thus, the transverse elements are not formed in one piece, but in two parts, and their length can be adjusted, for example, so that the load compartment cover, for example, can also be adjusted in the transverse direction of the vehicle. For this purpose, the slat devices, for example, can also be adjusted in the transverse direction of the vehicle by means of a respective adjustment device.For example, the load compartment cover could be adjusted so that it is only positioned behind one comfort seat by connecting the respective cross-element sections to one another, leaving the load compartment behind the other comfort seat uncovered and without a load compartment cover. This would allow, for example, taller loads / objects to be inserted only on one side while still having a load compartment cover for smaller loads / objects on the other side. In other words, the adjustment of the cross elements can be achieved using a mechanical or electrical adjustment device in which the cross element sections are telescopically pulled apart or pushed together to adjust the cover to the desired position.

[0023] In a further advantageous embodiment of the invention, the arched structures are mechanically coupled to one another, so that when one arched structure is adjusted, all the other arched structures are moved simultaneously. This makes it possible, when the load compartment cover is manually operated, for example by pulling on the largest arched structure, to automatically adjust all the other arched structures into the rest position or from the rest position to the use position. This mechanical coupling could be implemented using cables, locking elements or other adjustment mechanisms to enable simple and simultaneous adjustment of the entire load compartment cover. For example, a cable element could be arranged in the central region of one of the arched structures, which moves all the other arched structures synchronously when the largest arched structure is adjusted.This cable element would support the mechanical coupling of the individual arch structures and thus enable simultaneous adjustment without the need to adjust or adjust each arch structure individually.

[0024] In a further advantageous embodiment of the invention, it is provided that at least one arched structure comprises at least one tension element for manually adjusting the slat device. Such a tension element can be designed, for example, as a rope element, with / and / or a spring element, with / and / or a damper with / and / or a cable element, which, for example, has a free end which can be pulled in order to adjust the respective slat devices from the use position to the rest position and back. However, this tension element can also be integrated, for example, in a pulley or in another adjustment mechanism, so that the arrangement of, for example, an actuator or an operating element also enables, in particular, manual adjustment.

[0025] In another advantageous embodiment of the invention, a locking element is provided for adjusting the slat devices and for holding all arched structures in the use position and / or the rest position. This locking element is designed to hold the respective slats and / or the respective arched structures so that they cannot be released again, for example, while driving. In particular, the use position and / or the rest position are to be held without the arched structures, for example, falling back or folding back.In particular, the locking element could be static and made of, for example, a rubber material, so that adjustment between the positions is possible by overcoming force. Alternatively, however, the locking element can also be mechanical, in particular manual, whereby when a control element is operated, the locking element enables movement or adjustment between the positions. Finally, it would also be possible to design the locking element automatically or at least semi-automatically, whereby an electronic control element would enable adjustment, in particular manual adjustment, of the slat devices from the use position to the rest position and back.

[0026] In another advantageous embodiment of the invention, at least one actuator and / or one sensor device is arranged for at least partially automatic adjustment of the slat devices. In this case, an actuator, in particular an actuator coupled to the slat devices, and an adjustment mechanism are designed to enable adjustment between the positions at least partially automatically. In particular, all components are electronically coupled to one another and thus enable adjustment of the respective arch structures.For example, to provide an additional safety measure, a sensor device could be arranged in the cargo space to detect whether a collision with an object or, for example, a pet is about to occur, so that the at least partially automatic adjustment of the slat devices is at least stopped or a warning signal is generated. Further configurations and applications are also possible.

[0027] A further aspect of the invention relates to a method for operating a load compartment cover for a motor vehicle with two slat devices arranged opposite one another in the transverse direction of the vehicle in a loading space, each slat device comprising a plurality of slats rotatably connected to a respective axis of rotation, wherein each slat of a first slat device is connected to a corresponding slat of the other second slat device via a respective transverse element and form a respective floor structure with decreasing size arrangements, wherein the slat device can be moved between a rest position, in which the respective arch structures are moved together relative to the axis of rotation and due to the decreasing size arrangement, an arch structure always encompasses the next smaller one on the outer circumference, and a use position,in which the respective arch structures are pivoted relative to the respective axes of rotation and the respective transverse elements thereby at least partially cover the loading space, with a largest arch structure covering a longest pivoting path.

[0028] Each slat of the first slat assembly is thus connected to a corresponding slat of the second slat assembly via a respective cross member, creating an arched structure with a decreasing arrangement of sizes. In this method, the slat assembly can be adjusted between the rest position, in which the arched structures are nested, and the use position, in which the slats are pivoted and partially cover the cargo space.

[0029] In summary, the invention describes a load compartment cover and a method for adjusting the load compartment cover for motor vehicles, in which opposing slat devices with corresponding slats connected via transverse elements form a sloping arch structure which can be pivoted between a rest position and a use position in order to cover the load compartment.

[0030] Further features of the invention emerge from the claims, the figures, and the description of the figures. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown alone in the figures, can be used not only in the respective combinations specified, but also in other combinations or on their own.

[0031] The invention will now be explained in more detail using a preferred embodiment and with reference to the drawings. They show: Fig. 1 a schematic perspective view of a possible embodiment of a load compartment cover for a motor vehicle; Fig. 2 a schematic side view of the possible design of the load compartment cover in a rest position; Fig. 3 a schematic side view of the possible configuration of the load compartment cover in an intermediate position between the rest position and a use position; and Fig. 4 a schematic side view of the possible design of the load compartment cover in the use position.

[0032] In the figures, identical and functionally identical elements are provided with the same reference symbols.

[0033] Fig.1 shows a schematic perspective view of a possible embodiment of the load compartment cover 10 for a motor vehicle. In particular, the load compartment cover 10 is shown in a cargo space 12 having a cargo floor. Furthermore, a vehicle seat 16 is shown in the rear area 18 of this motor vehicle, behind which the load compartment cover 10 is arranged. The load compartment cover is provided as a covering option in the cargo space 12, which is particularly easy to adjust and operate, particularly in the case of a vehicle seat 16 designed as a comfort seat, while also using as little space as possible.

[0034] This cargo compartment cover 10 offers a flexible way to at least partially cover the cargo area 12, while being particularly easy to adjust and operate, especially when using a comfort seat in the rear. The cargo compartment cover 10 replaces conventional roller blinds attached to bench seats and offers a space-saving and adaptable alternative, especially in combination with the comfort seats.

[0035] The load compartment cover 10 comprises two slat devices 20a, 20b arranged opposite one another in the vehicle transverse direction Y and in the load compartment 12. Thus, a first slat device 20a and a second slat device 20b are shown, each comprising a plurality of slats 22a, 24a, 26a, 22b, 24b, 26b rotatably connected to a respective rotation axis A.

[0036] Here, it is provided that each slat 22a, 24a, 26a of the first slat device 20a is connected to a corresponding slat 22b, 24b, 26b of the second slat device 20b via a respective cross element 28, 30, 32. Thus, the slats 22a, 24a, 26a of the first slat device 20a and the other slats 22b, 24b, 26b of the second slat device 20b correspond. The slats 22a, 24a, 26a of the first slat device 20a and the slats 22b, 24b, 26b of the second slat device 20b are not only arranged correspondingly, but also have the same size and arrangement. This ensures that they are precisely aligned and run parallel, enabling a uniform, symmetrical covering of the loading space 12.

[0037] The transverse elements 28, 30, 32 thus each connect a slat 22a, 24a, 26a of the first slat arrangement 20a with a corresponding slat 22b, 24b, 26b of the second slat arrangement 20b. They are designed to stably connect the slats 22a, 24a, 26a, 22b, 24b, 26b to one another and enable a uniform movement of both slat arrangements 20a, 20b. The transverse elements 28, 30, 32 are preferably of equal width and length to provide a symmetrical connection between the corresponding slats 22a, 24a, 26a, 22b, 24b, 26b of the two slat arrangements 20a, 20b. Nevertheless, the cross elements 28, 30, 32 could also be designed in different dimensions to meet specific adaptations or requirements.

[0038] The slats 22a, 24a, 26a, 22b, 24b, 26b and the transverse elements 28, 30, 32 result in respective arched structures B1, B2, B3 with a decreasing size arrangement. This means that the outermost arched structure B1 is larger than the middle arched structure B2, which in turn is larger than the inner arched structure B3. An arrangement or design of the load compartment cover 10 with slat devices 20a, 20b with many more slats would also provide a much larger arrangement of arched structures, which would also be provided in this systematic, decreasing size arrangement.

[0039] The slat devices 20a, 20b are adjustable between a rest position P1 and an adjustment position P2. In the rest position P1, the respective arched structures B1, B2, B3 are moved together relative to the rotation axes A and, due to the decreasing size arrangement, the larger arched structure B1, B2, B3 always encompasses the next smaller one on the outer circumference. In the use position, the respective arched structures B1, B2, B3 are pivoted relative to the respective rotation axes A and the respective transverse elements 28, 30, 32 thus at least partially cover the loading space 12, with the largest arched structure B1 here covering the longest pivoting path Ay. In this case, it is provided that the transverse elements 28, 30, 32 are flat and, above all, are angled such that, in the use position P2, they form a continuous, in particular flat, surface 34 relative to one another.This surface 34 is the covering surface of the load compartment cover 10, which thus at least partially divides the loading space 12. Objects can be placed on this continuous surface 34, for example; in particular, it can thus be used as a so-called parcel shelf. Below the continuous surface 34 is the loading space, into which respective objects and items are inserted and held by the continuous surface. The continuous surface 34 represents the load compartment cover 10.

[0040] In order to provide particularly advantageous protection, it is provided that the rotation axes A of the respective slat devices 20a, 20b are arranged in the loading space floor 14 and / or at the front in the vehicle's longitudinal direction, thereby providing as much space as possible in the loading space 12 and covering the respective objects by the resulting continuous surface 34, and protecting the interior. It is possible for the slat devices 20a, 20b to be translationally adjustable along the loading space 12 in order to provide as many positioning and adjustment options as possible for the loading space cover 10. For example, the slat devices 20a, 20b can be adjusted forwards or backwards in the vehicle's longitudinal direction. Alternatively, the slat devices can also be adjusted upwards or downwards in the vehicle's vertical direction.In a further embodiment, it would also be possible for the slat devices 20a, 20b to be adjusted from left to right in the vehicle transverse direction Y, whereby the respective transverse elements 28, 30, 32 can be formed, for example, in two parts by two separable transverse element parts. Thus, it is possible to adjust the respective attachment points of the slat devices 20a, 20b along the loading space via respective adjustment devices in such a way that many different configurations are provided for the loading space cover 10.

[0041] It is also possible for the arched structures B1, B2, B3 to be mechanically coupled to one another and / or for all the others to be adjustable when one arched structure B1, B2, B3 is adjusted. This means that adjusting one arched structure B1, B2, B3 results in all the other arched structures B1, B2, B3 also being adjusted, in order to enable particularly simple and intuitive adjustment of the load compartment cover 10. For example, a tension element 36 can be arranged on one of the arched structures, for example on the largest outermost arched structure B1, by means of which the slat devices 20a, 20b can be adjusted into the rest position and / or into the use position.For example, a tension element 36 could be a cable element, which is arranged, in particular, centrally on the transverse element 28 of the first arch structure B1 and thus of the largest arch structure B1, whereby pulling the cable element and thus the tension element 36 would enable the largest arch structure B1 to be returned to the rest position P1. By pulling back the largest arch structure B1, all other arch structures B2, B3 that are mechanically coupled to the largest arch structure B1 would also be returned to the rest position.

[0042] In order to then also be held in this rest position P1, a locking element 38 can be arranged, for example, which can be designed as a static mechanical part, for example as a silicone element, through which a pulling over would only occur under a greater force, so that the locking element 38 can in particular hold all arch structures B1, B2, B3 in the respective position. When returning to the use position P2, the user would have to apply the force to pull over this locking element 38 again, whereby the arch structures B1, B2, B3 could be released again and brought back into the use position P2.Alternatively, however, this locking element can also be mechanically adjustable, for example also comprise spring elements or an operating element for mechanical adjustment and / or could also be designed fully automatically and adjusted by electronic signals so that the adjustment of the slat devices 20a, 20b can be brought between the use position P2 and the rest position P1.

[0043] Furthermore, it is also possible for at least one actuator 40 and / or at least one sensor device 42 to be arranged for the at least partially automatic adjustment of the slat devices 20a, 20b, wherein here an actuator is designed to adjust the slat devices 20a, 20b between the positions P2, P1 via a respective adjustment mechanism. Alternatively, each slat device 20a, 20b can also comprise its own actuator 40. In order to provide a safety measure, it is provided that the sensor device 42 is designed to detect whether an object and / or a pet and / or other items are arranged in the loading space 12, so that the use position P2 is blocked. In this case, a warning signal can be generated or the adjustment from the use position to the rest position or back can be prevented.

[0044] In summary, the invention proposes a load compartment cover with a compartment system.
