DETAILED DESCRIPTION

[0053] As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.

[0054] FIGS. 1A-1B, 2A-2B, and 3 show an adjusting device V by way of which a storage compartment for a vehicle is provided in various views and positions of an adjusting part of the adjusting device V that is configured as an adjustable front plate 1. The adjusting device V herein may be configured as a storage compartment or adjusting module which in a pre-assembled for the functional state is capable of being attached in an installation space provided therefore on a dashboard of a motor vehicle. In one variant, attaching the adjusting device V is provided in a trunk, on a center console, on the vehicle seat (for example in the region of a side, on a rear wall, or below the seat cushion of the vehicle seat) or on a vehicle door (for example as part of the door module) of a motor vehicle.

[0055] The adjusting device V defines a storage space SR of the storage compartment, the volume thereof being capable of being set in a variable manner by way of the adjustable front plate 1. The front plate 1 herein lies opposite a support part of the adjusting device V in the form of a bearing plate L, the support component defining a rear wall of the storage space SR. Two mutually opposite lateral parts S1 and S2 which define in each case one lateral wall of the storage space SR run between the bearing plate L and the front plate 1. The length of a lateral wall of the storage space SR that is formed by a lateral part S1 or S2 may be modified in that the lateral parts S1 and S2 are in each case configured so as to be flexible and foldable, for example in the manner of bellows, in particular by adjusting the front plate 1. The front plate 1 in the variant of embodiment illustrated along a deployment or adjustment direction x along an adjustment axis or spatial axis x, as well as be pivoted about a pivot axis (about an axis parallel to the spatial axis y) that runs perpendicular to the spatial axis x, may, for example, be adjusted in a translatory manner relative to the bearing plate L. Not only the volume of the storage space SR but also the shape thereof may be variably adapted in such a manner. For example, the storage space SR in FIGS. 1A and 1B is wedge-shaped or funnel-shaped on account of the front plate 1 that is aligned so as to be inclined to the bearing plate L, wherein the larger base area lies at the top and defines an access opening for incorporating items into the storage space SR. However, the storage space SR may also be configured so as to be cuboid, for example, by pivoting the front plate 1 in a corresponding manner.

[0056] This variability of the storage space SR is controlled by four link chains 2A, 2B, 3A, and 3B which are connected to the front plate 1 at the four corner points of a virtual rectangle on an internal side 1B of the front plate 1 that faces the storage space SR. Each of the link chains 2A, 2B, 3A, and 3B has an end chain-link 21 or 31 which is in each case articulated on one of four articulation elements 10.1, 10.2, 10.3, and 10.4 that are rigidly connected to the front plate 1.

[0057] The four link chains 2A, 2B, and 3A, 3B are presently mutually disposed in such a manner that two (upper) link chains 2A and 2B are deployable in a mutually parallel manner from and retractable into a common xy-plane. The two upper link chains 2A and 2B in turn run so as to be parallel to two further (lower) link chains 3A and 3B which are likewise retractable into and deployable from a common xy-plane. Chain links 20 or 30 of the respective link chain 2A, 2B, of 3A, 3B are in each case connected to one another in unarticulated manner (by way of an articulated connection 201 or 301) such that a non-deployed portion of the respective link chain 2A, 2B, 3A, or 3B is flexible per se. However, the individual chain links 20 or 30 in a deployed state bear on one another in a blocking manner such that a deployed portion of the link chain is (flexibly') rigid and a deployed portion of each link chain 2A, 2B, 3A, or 3B thus projects in the manner of a rod from the bearing plate L and hereby may hold the front plate 1 in a desired spatial position in relation to the bearing plate L. A traction means such as a traction cable which mutually pretensions the individual chain links 20, 30 in order for the chain links 20, 30 in the deployed state to be brought to bear on one another such that the chain links 20, 30 are no longer mutually repositionable may be provided for the blocking bearing of the deployed chain links 20 or 30 of the link chain 2A, 2B, 3A, and 3B. Link chains which become rigid when deployed and otherwise of flexible are widely known in principle.

[0058] Drive installations 4A, 4B, 5A, and 5B are part of the adjusting device V for retracting and deploying the link chains 2A, 2B, 3A, and 3B in a manner activated by an external force. Each link chain 2A, 2B, 3A, and 3B herein is assigned in each case one drive installation 4A, 4B, 5A, or 5B such that each of the link chains 2A, 2B, 3A, and 3B is adjustable individually and thus independently of the other link chains. Each drive installation 4A, 4B, 5A, and 5B has inter alia a chain housing 40A, 40B, 50A, or 50B in which a retracted portion of the respective associated link chain 2A, 2B, 3A, or 3B may be received.

[0059] Each of the chain housings 40A, 40B, 50A, and 50B herein is configured so as to be L-shaped. The associated link chain 2A, 2B, 3A, and 3B with in each L-shaped chain housing 40A, 40B, 50A, and 50B is thus deflected by approx. 90 when retracting and when the individual chain links 20 or 30 no longer bear on one another in a blocking manner. The adjusting device V in such a manner may be of a comparatively compact construction and, despite a comparatively large adjustment path front plate 1 predefined by the link chains 2A, 2B, 3A, and 3B, may be conceived so as to be shorter along the x-axis and thus to require less installation space.

[0060] Each chain housing 40A, 40B, 50A, or 50B configures a housing part 400A, 400B, 500A, or 500B having a guide duct 402A, 402B, 502A, 502B for the retracted portion of the respective link chain 2A, 2B, 3A, or 3B. For simpler assembling and for protecting the respective guide duct 402A, 402B, 502A, or 502A from dirt, the respective housing part 400A, 400B, 500A, or 500B is presently closed off by a cover 401A, 401B, 501A, or 501B that is capable of being separately assembled.

[0061] In order for the attachment installations 4A, 4B, 5A, and 5B be able to be accommodated in an ideally compact manner behind the bearing plate L, the drive installations 4A, 4B, 5A, and 5B are disposed on top of one another in pairs. Two (upper) drive installations 4A and 4B, along a spatial direction z that runs so as to be perpendicular to the spatial direction x along which the front plate (1 may be adjusted in a translatory manner by way of the link chains 2A, 2B, 3A, and 3B, are thus disposed above the two further (lower) drive installations 5A and 5B. Furthermore, it is provided in the case of each pair of drive installations 4A, 4B, and 5A, 5B that one chain housing 40A or 50B extends at least partially about the other chain housing 40B or 50A. Furthermore, the chain housings 40A, 40B, and 50A, 50B run so as to be partially mutually inclined.

[0062] The drive installations 4A, 4B, and 5A, 5B for the upper and the lower chain links 2A, 2B, and 3A, 3B presently are configured in identical pairs. In other words, the drive installation 4A and 4B for the upper link chains 2A and 2B are configured so as to be identical to the drive installations 5A and 5B for the lower link chains 3A and 3B. The upper drive installations 4A and 4B are merely assembled so as to be rotated by 180. Accordingly, only two different types are required for the four drive installations 4A/5B, 4B/5A four driving the total of four link chains 2A, 2B, 3A, and 3B in a manner activated by an external force.

[0063] Each drive installation 4A, 4B, 5A, and 5B presently has an electromotive drive 6A, 6B, 7A, or 7B which is established on the respective chain housing 40A, 40B, 50A, or 50B. An individual link chain 2A, 2B, 3A, or 3B may be deployed from the respective chain housing 40A, 40B, 50A, or 50B by way of the electromotive drive 6A, 6B, 7A, or 7B such that the chain links 20, 30 of one link chains 2A, 2B, 3A, or 3B are pushed out of an associated deployment opening in the form of a longitudinal slot LA, LW, LC, or LD on the bearing plate L and thus may adjust the front plate 1 toward the front along the spatial axis x. In the deployment along the spatial axis x the volume of the storage space SR is increased in relation to an initial position which is illustrated in FIG. 3 and in which the front plate 1 presently is at a minor spacing from the bearing plate L, presently so as to be substantially parallel to the bearing plate L.

[0064] When only the upper link chains 2A, 2B are then deployed from the initial position, for example, the front plate 1 is pivoted about the lower articulation elements 10.3 and 10.4 (and thus about a lower pivot axis defined herein) on which the lower link chains 3A and 3B are articulated. On account thereof, not only the shape of the storage space SR is modified such that the storage space SR appears to be wedge-shaped or funnel-shaped, but also the volume of the storage space SR is increased as compared to the initial position of the front plate 1. By contrast, when the lower link chains 3A, 3B are deployed along the spatial axis x while the upper link chains 2A and 2B remain arrested or are deployed more slowly, the front plate 1 is pivoted about the upper articulation elements 10.2 and 10.1 (and thus about an upper pivot axis defined herein), and the storage space SR is increased on account thereof, optionally with the upper link chains 2A and 2B being arrested, without achieving or increasing herein an access opening to the storage space SR. The link chains 2A, 2B, 3A, and 3B herein may in principle also be deployed in a mutually non-synchronous manner. However, asynchronous adjustment of all link chains 2A, 2B, 3A, and 3B is ultimately possible so as to achieve a purely translatory adjustment of the front plate 1 (that is to say without any superimposed pivoting movement at the articulation elements 10.1 10.4).

[0065] Additionally to adjusting the front plate 12 different first adjustment positions so as to vary the volume and/or the shape of the storage space SR, the front plate 1 presently by way of the link-chain drive having the four link chains 2A, 2B, 3A, and 3B thereof of the adjusting device V is also adjustable to a second adjustment position, referred to as the table position which is illustrated in FIGS. 2A and 2B. The front plate 1 herein by way of the two lower link chains 3A and 3B, with the upper link chains 2A and 2B arrested, is pivoted upward such that an external side 1A of the front plate 1 defines a deposition face as part of a table formed by the front plate 1. The front plate 1 herein by the two lower link chains 3A and 3B is pivoted about the end chain links 21 of the upper link chains 2A, 2B such that the front plate 1 runs so as to be substantially horizontal and items may be set down on the external side 1A of the front plate 1.

[0066] In order for the front plate 1 for assuming the table position to be pivoted upward by means of the two lower link chains 3A, 3B, the drive installations 5A and 5B of the lower link chains 3A, 3B by way of a bearing portion 51A and 51B are mounted so as to be rotatable relative to the support plate L. Each bearing portion 51A and 51B of the two drive installations 5A and 5B herein configures a rotary bearing journal 510A or 510B. The two drive installations 5A and 5B including the chain housings 50A and 50B thereof by way of the two rotary bearing journals 510A, 510B are then mounted so as to be rotatable about a rotation axis D2 relative to the bearing plate L. By way of the deployment openings for the link chains 3A and 3B that are embodied as longitudinal slots LC and LD on the bearing plate L it is here in also ensured that the individual link chains 3A and 3B across a defined angular range may be deployed obliquely to the bearing plate L. The link chains 3A and 3B may thus not only be deployed so as to be substantially perpendicular to the bearing plate L but also at a variable angle in a range from 90 to, for example, 45, in particular in a range from 90 to 60, to the bearing plate L.

[0067] The rotatable mounting of the drive installations 5A and 5B furthermore also serves for equalizing different spacings in the case of upper and lower link chains 2A, 2B, 3A, and 3B that are deployed to a great extent. Against this background, the drive installations 4A and 4B may optionally also be mounted so as to be rotatable relative to the bearing plate L by way of rotary bearing journals 410A and 410B that are configured on the bearing portions 41A and 41B.

[0068] The volume of the storage space SR may in principle be variably adjustable in a manner controlled by a user. Consequently, a user may set the size of the storage space SR by retracting and deploying the four link chains 2A, 2B, 3A, and 3B depending on the desired space requirement.

[0069] Alternatively or additionally, a self-acting adaptation of the storage space volume may also be provided. To this end, the adjusting device V according to FIG. 3 has at least one sensor element 9A on the bearing plate L, for example. A loading state of the storage space SR in this instance is capable of being detected by way of the sensor element 9A, for example, and a size of the storage space SR is capable of being automatically adapted as a function thereof. To this end, the sensor element 9A may operate in a capacitive or optical manner and identify to what extent the available storage space SR in the current adjustment position of the front plate 1 is utilized. In this manner, it may be detected by a sensor whether the volume of the storage space SR should optionally be increased or decreased in order for further items to be able to be received or the space requirement of the storage compartment be decreased.

[0070] The sensor element 9A herein is coupled to a sensor installation SE, for example, which has an evaluation logic for measured signals received by the sensor element 9A. When a loading state which is intended to lead to an automatic adaptation of the volume of the storage space SR is identified by way of the evaluation logic of the sensor installation SE, the sensor installation SE correspondingly actuates the drives 6A, 6B, 7A, and 7B of the drive installations 4A, 4B, 5A, and 5B so as to deploy and/or retract the link chains 2A, 2B, 3A, and 3B for the adjustment of the front plate 1.

[0071] Alternatively or additionally to sensor element 9A four detecting a loading state of the storage space SR, the adjustment direction V may also have a sensor element 9B on the front plate 1 so as to detect in a non-contacting manner an operating incident by a user in order for the storage space SR be rendered accessible to the user and/or for the storage space SR be closed. Part of the sensor element 9B that herein is disposed on the front plate 1 may be at least one electrode, for example for detecting in a capacitive manner a gesture of a user carried out in front of the external side is 1A of the front plate 1 as an operating incident for opening or closing the storage compartment. Such a sensor element 9B in this instance may thus also be coupled in a corresponding manner to a sensor installation SE for controlling the drives 6A, 6B, 7A, and 7B.

[0072] In principle, only one sensor element 9A or 9B by means of which an operating incident in the form of a gesture carried out by a user for adjusting the front plate 1 as well as a loading state of the storage SR is capable of being detected may also be provided. The respective sensor element 9A and 9B herein may also be capable of being operated in different operating modes, for example, so as to be utilizable for control by gesture in a first operating mode and for an automatic adjustment of the front plate 1 as a function of a loading state in a second operating mode.

[0073] The drives 6A, 6B, 7A, and 7B may be electromotive and by way of the gearbox unit act on the chain links 20, 30 of the link chains 2A, 2B, 3A, and 3B so as to adjust the latter. Each drive 6A, 6B, 7A, or 7B presently is coupled to a worm gear mechanism, for example, so as to convert a drive torque generated by the respective drive 6A, 6B, 7A, or 7B for retracting and deploying the associated link chain 2A, 2B, 3A, or 3B. A drive 6B or 7A, illustrated in exemplary manner in FIG. 4, thus acts in each case by way of a gear wheel element in the form of a worm R on a worm gear 80 of a rotatably mounted drive element 8. A chain link here wheel 81 is provided on the drive element 8 so as to be rotationally fixed to the worm gear 80. The chain link gear wheel 81 meshes with a toothed drive face 200 or 300 of A chain link 20 or 30. In that a torque by way of the worm R is transmitted to the worm gear 80 and the chain link gear wheel 81 is thus rotated in one of two potential rotating directions, a chain link 20 or 30 that meshes with the chain-link gear wheel 81 is pushed in one or the other direction along the guide duct 402B, 502A. In that the successive chain links 20 and 30 then likewise mesh with the chain-link gear wheel 81, the rotating movement of the chain-link gear wheel 81 results in the respective link chain 2A, 2B, 3A, or 3B being retracted or deployed, depending on the rotating direction.

[0074] As is yet again visualized by way of the plan view of FIG. 5, the use of dedicated drive is 6A, 6B, 7A, 7B for a pair of upper or lower link chains 2A/2B and 3A/3B also permits an un-synchronous adjustment of the link chains 2A, 2B, or 3A, 3B of a pair of link chains 2A/2B and 3A/3B. The front plate 1 may thus not only be pivoted about pivot axes that run so as to be parallel to the spatial axis y and be displaced parallel to the spatial axis x. Rather, a pivoting movement about a further pivot axis which runs so as to be parallel to the spatial axis z which is oriented so as to be perpendicular to the two afore-mentioned spatial axes x and y is also possible.

[0075] The front plate 1 by way of the use of the link chains 2A, 2B, 3A, and 3B is thus variably adjustable in different ways so as to be able to adapt the shape and/or the volume of the storage space SR. Furthermore, the front plate 1 which forms an external visible face of the storage compartment, by way of the use of the link chains 2A, 2B, 3A, and 3B is also pivotable to a table position such that various (comfort) functions may be reproduced by way of a storage compartment having the adjustment direction V. In this context it is also to be pointed out that the use of four link chains 2A, 2B, 3A, and 3B is of course not mandatory for the illustrated adjustability of the front plate 1. A translatory adjustability and pivotability of the front plate 1 could also be achieved, for example, by way of two link chains, and upper and lower link chain.

[0076] As one example, a holding installation for establishing and arresting a storage-space insert may be provided on the deployed portions of the link chains 2A, 2B, 3A, and 3B and/or the flexible lateral parts 51 and S2. Such an insert may be configured so as to be pouch-shaped or bag-shaped, for example, and/or integrates the flexible lateral parts 51 and S2, herein can be separable from the bearing plate L in the case of an opened storage compartment. The insert, independent of the disposal in the vehicle, may thus be capable of being utilized as a transport container.

[0077] The holding installation for such an insert may be formed, for example, by hooks on a chain link 20, 30 or a plurality of chain links 20, 30, and a corresponding insert being capable of being cooked on the hooks. Alternatively or additionally, at least one magnet may be provided for establishing the insert according to the intended use on the link chains 2A, 2B, 3A, and 3B and/or the front plate 1 as part of the holding installation.

[0078] A rack may also be provided instead of the at least one link chain 2A, 2B, 3A, or 3B. The lower chain links 3A and 3B in one variant may furthermore be replaced by a scissor arm or by a plurality of scissor arms which engage on the front plate 1. Instead of a link-chain drive having the link chains 2A, 2B, 3A, and 3B, a lever mechanism may in principle be provided for varying the volume of the storage space SR in a manner activated by an external force, on the one hand, and for pivoting the front plate 1 to a table position in which the front plate 1 is capable of being utilized as a tabletop, on the other hand.

[0079] While exemplary embodiments are described above, it is not intended that these embodiments describe all possible forms of the invention. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention. Additionally, the features of various implementing embodiments may be combined to form further embodiments of the invention.

However, it should be understood that the use of these terms is for illustrative purposes only with respect to one embodiment. And, use of reference numbers correlating a certain term that is both illustrated in the Figures and present in the claims is not intended to limit the claims to only cover the illustrated embodiment.
