Description

The invention relates to a storage device for a motor vehicle, by means of which a storage surface is provided on which a user of the motor vehicle can store one or more objects. The storage device has a base plate, an extraction element mounted displaceably with respect to the base plate, and a flexible storage element which is fastened on the one hand to the base plate and on the other hand to the extraction element, such that the storage element is arranged between the base plate and the extraction element in a first position of the extraction element and forms at least one storage surface in a second position of the extraction element, wherein, when the extraction element is displaced from the direction of the first position in the direction of the second position, the storage element is elastically tensioned, such that it exerts a restoring force directed towards the first position on the extraction element. The invention further relates to a motor vehicle having a storage device.The prior art discloses, for example, the publication DE 198 04 461 C1. This relates to a storage device for a vehicle interior with an inflatable storage part made of an elastic material, which can be transferred from a gas-depleted non-use state to a gas-filled use state with the aid of a gas supply device. The storage device is designed such that a storage area can be provided at any time in the vehicle interior, which in the event of a collision with its user does not form a risk of injury to the user. This is achieved by the storage part being fastened in a region of its circumference to a trim element in the vehicle interior, the storage part extending, in the use state, from the trim element into the vehicle interior, the storage part being able to be accommodated in a receptacle provided in the trim element in the non-use state, and the gas supply device being accommodated in the trim element.Furthermore, the document DE 10 2019 210 001 B4 discloses a motor vehicle, having at least one seat, a storage device, which is assigned to at least one of the at least one seat and which is in particular usable during autonomous driving operation, having a storage plate, in particular in the form of a table, and a collision detection device for detecting a collision of the motor vehicle with an object, wherein the storage plate has at least one collapse actuator, which reduces said collapse actuator on the basis of a use state and / or which moves or deforms said collapse actuator on the basis of a risk of injury for an occupant located in the assigned seat, having an assigned triggering unit, wherein the triggering unit is designed for triggering the collapse actuator in the presence of a collision signal of the collision detection device which indicates a collision.The document DE 10 2022 129 172 B3 relates to an adjustable table arrangement for a means of transport, comprising an L-shaped carrier with a first carrier section and a second carrier section adjoining the first carrier section, which beam section protrudes at an angle therefrom, wherein a support structure, which can be telescopically extended from the second carrier section, is provided with a flexible and flat support fastened thereto, wherein the support can be extended together with the support structure and covers the support structure.Furthermore, the documents DE 2009 046 688 A1, DE 10 2018 132 163 A1 and U.S. Pat. No. 2017 / 0 113 589 A1 are known from the prior art.It is provided here that the shelf plate has a sheath defining a pressure chamber and providing a shelf surface on its upper side, wherein the pressure chamber is filled with a gas in the use state, wherein vertically extending support threads connecting the upper side and the lower side of the sheath are provided in the pressure chamber, in particular according to the drop-stitch method.It is the object of the invention to propose a storage device for a motor vehicle, which has advantages over known storage devices, in particular is simple and cost-effective in design and can be retrofitted.This is achieved according to the invention with a storage device for a motor vehicle having the features of claim 1. It is provided that the pull-out element is mounted with respect to the base plate in such a way that the restoring force produced by the storage element holds the pull-out element in the second position corresponding to an over-center point.In principle, a base plate, an extraction element that can be displaced with respect to the base plate, and a flexible storage element are present, which are fastened on the one hand to the base plate and on the other hand to the extraction element, so that the storage element is arranged between the base plate and the extraction element in a first position of the extraction element and forms at least one storage surface in a second position of the extraction element.Advantageous embodiments with expedient developments of the invention are specified in the dependent claims. It is pointed out that the exemplary embodiments explained in the description are not restrictive; rather, any variations of the features disclosed in the description, the claims and the figures can be realized.The storage device is preferably a component of the motor vehicle, but can naturally also be separate from the latter, in particular until the storage device is mounted on or in the motor vehicle. The depositing device serves for providing the depositing surface on or in the motor vehicle, preferably in an interior of the motor vehicle. For example, the storage device is arranged and fastened on an instrument panel, on a seat of the motor vehicle, in particular on a rear side of the seat, on a door or the like.It is known to use foldable or pivotable storage elements which are stored in a space-saving manner in a first position and provide the storage surface in a second position. However, such depositing elements are space-consuming due to the necessary mechanics. In addition, measures must usually be taken to arrange the storage element in the event of an accident of the motor vehicle in order to reduce a risk of injury to an occupant of the motor vehicle.The aim is therefore to provide a storage device which is of simple construction and can therefore be produced cost-effectively. In addition, the storage device should be suitable in particular for retrofitting, and it can therefore also be mounted subsequently on or in the motor vehicle. Moreover, no complicated measures are necessary in order to arrange the storage device in an accident-proof manner in the event of an accident of the motor vehicle.The storage device according to the invention has the base plate, the pull-out element and the storage element. The base plate serves in particular for fastening the storage device to an element of the motor vehicle, in particular an interior fitting element of the motor vehicle, such as, for example, the dashboard, the seat, the door or the like. The base plate is preferably designed as a rigid element and is substantially plate-shaped, i.e. it has in each case larger dimensions in two directions perpendicular to one another, namely a first and a second direction, than in a third direction perpendicular in each case to the two directions. For example, the dimensions of the base plate in the first direction and / or its dimensions in the second direction are each greater than the dimensions in the third direction by a factor of at least 10, at least 25 or at least 50.Furthermore, the depositing device has the pull-out element. This is mounted displaceably with respect to the base plate. This means that the pull-out element can be displaced rotationally and / or translationally with respect to the base plate by a user. For example, a handle is arranged or formed on the pull-out element, by means of which handle the user can engage on the pull-out element. Preferably, the pull-out element is mounted directly on the base plate, that is to say the pull-out element is connected directly to the base plate via a corresponding mounting. However, it can also be provided that only a direct mounting of the pull-out element of a base plate is realized. In this case, the pull-out element engages via the bearing on another element, which is ultimately connected to the base plate or is arranged in a fixed manner with respect to the base plate.The base plate and the pull-out element are connected to one another via the flexible storage element. The storage element is thus fastened on the one hand to the base plate and on the other hand to the pull-out element. The depositing element serves to produce the depositing surface. This means that the storage surface is formed at least temporarily by the storage element or is present on the storage element. The placement surface is to be understood as a surface on which at least one object can be placed at least temporarily by the user. The placement surface is preferably configured to be planar completely or at least in regions, in order to enable a stable parking of the at least one object.The pull-out element can be arranged in different positions with respect to the base plate, namely at least in the first position and in the second position. The first position can also be referred to as the non-use position and the second position as the use position. In the first position, the pull-out element is arranged closer to the base plate than in the second position, in particular a geometric center of gravity of the pull-out element is further away from a geometric center of gravity of the base plate in the second position than in the first position.In the first position of the pull-out element, the storage element is to be arranged between the base plate and the pull-out element, so that the storage element and the storage device have overall compact dimensions. In the second position of the pull-out element, the storage element is clamped between the base plate and the pull-out element to form the storage surface. In order to enable simple displacement of the pull-out element between the first position and the second position or vice versa, the storage element is designed to be flexible. This is to be understood as meaning that the depositing element is reversibly deformable.Preferably, the storage element has a first shape or form in the first position of the pull-out element and a second shape or form in the second position of the pull-out element, which is different from the first shape. The shape is to be understood in particular as an outer contour which differs between the first position and the second position of the pull-out element. For example, the storage element has smaller first dimensions in one direction in the first position of the pull-out element and larger second dimensions in the second position.With the described embodiment of the depositing device, the already mentioned advantages are achieved. In particular, the described depositing device is structurally simple and can be produced cost-effectively. In addition, due to the flexible configuration of the storage element, additional measures for securing the storage device in the event of an accident of the motor vehicle can be dispensed with, since there is no risk of injury due to the flexible configuration of the storage element.A further development of the invention provides that the storage element has regions with different stiffnesses. The storage element is basically configured in one piece. However, it can be composed of different regions which are distinguished by different strengths or stiffnesses. For example, two regions with higher stiffness are connected to one another via a region with lower stiffness. Preferably, the second region is present here in the form of a film hinge or the like. In such a configuration, the depositing element can be configured in one piece and materially uniform, since the lower stiffness of the second region is preferably realized by a smaller material thickness.However, it can also be provided that the regions consist of different materials which are connected to one another in a materially integral manner. In this case, the storage element is produced, for example, by means of a multicomponent injection molding process. The support element composed of the plurality of regions is configured, for example, in the manner of a bellows, i.e. is present at least in regions as a bellows. This achieves simple unfolding and folding of the storage element during the displacement of the pull-out element from the first position into the second position or vice versa.A further development of the invention provides that the flexible depositing element is elastic due to at least regional design from an elastic material. The flexible depositing element consists in regions or completely of the elastic material and is accordingly itself elastic. The elastic material is understood to mean a material which is reversibly deformable by the action of force starting from an initial shape and automatically returns to its initial shape due to its elasticity in the event of the action of force being omitted. The elasticity of the storage element is effected, for example, by entropy elasticity or rubber elasticity.In order to realize the elasticity of the storage element, it consists of the elastic material, preferably of an elastomer. For example, the support element is in the form of a plastic membrane which is relaxed in the first position of the pull-out element and, in the second position of the pull-out element, is braced between the base plate and the pull-out element and thereby forms the support surface. With the described embodiment of the depositing device, the already mentioned advantages are achieved in a particularly cost-effective and simple manner.A further development of the invention provides that the pull-out element is mounted rotatably and / or translationally displaceably with respect to the base plate about an axis of rotation along a displacement path, in particular on the base plate. The pull-out element is mounted in principle in any desired manner so as to be displaceable or displaceable with respect to the base plate. The mounting can be configured such that a rotational movement about the axis of rotation and / or the movement along the displacement path is permitted, in particular exclusively. Preferably, the pull-out element is mounted so as to be displaceable either rotationally or translationally, but not rotationally and translationally.In the case of the mounting for translatory displacement, the pull-out element is displaceable along the displacement path. The displacement path can in principle run as desired, preferably it is continuously straight, so that the bearing ensures a linear displacement of the pull-out element. As already mentioned, the pull-out element is preferably mounted on the base plate itself, but an indirect or indirect mounting can also be realized. With the described mounting of the pull-out element with respect to the base plate, a storage device which is easy to handle is provided.The invention provides that, when the pull-out element is displaced from the direction of the first position toward the second position, the storage element is elastically tensioned, so that it exerts a restoring force on the pull-out element, which restoring force is directed toward the first position. The storage element is arranged between the base plate and the pull-out element in such a way that it is elastically deformed when the pull-out element is displaced in the direction of the second position. Accordingly, it causes a force between the base plate and the pull-out element which is directed towards producing the original shape of the storage element, namely the restoring force. When displacing the pull-out element in the direction of the second position, the restoring force must be overcome by the user of the depositing device in order to successfully produce the depositing surface by means of the depositing element.For example, it is provided that the pull-out element, after its displacement into the second position, is fixed therein, i.e. to generate a holding force which is opposed to the restoring force, in particular by means of a locking mechanism. By fixing the pull-out element in the second position, the storage element remains in its shape corresponding to the second position, so that the storage surface is present. The restoring force can be used, for example after releasing the locking, for displacing the pull-out element out of the second position in the direction of the first position. The elastic tensioning of the depositing element ensures a planar configuration of the depositing surface.The invention provides that the pull-out element is mounted with respect to the base plate in such a way that the restoring force produced by the storage element holds the pull-out element in the second position corresponding to an over-center point. The pull-out element is in this respect preferably mounted with respect to the base plate by means of a lever mechanism. The lever mechanism is configured in such a way that it introduces the restoring force, which is produced by the storage element, into its bearing in at least one position of the pull-out element in such a way that the pull-out element is free of forces with respect to its two positions, that is to say is not forced by the restoring force in the direction of the first position or in the direction of the second position. This position is at a dead point of the lifting mechanism.It is provided that the second position is present at the over-center point of the lever mechanism or corresponds to this. This means that the second position is arranged on the side of the dead center opposite the first position, so that the dead center must be exceeded in order to reach the second position from the first position. In the second position, the restoring force still acts on the pull-out element, but pushes it away from the first position, in particular at an end stop, which prevents a displacement of the pull-out element in the direction of the first position beyond the second position and is arranged or configured accordingly. In such a configuration of the storage device, it is possible to dispense with a locking for the pull-out element, since the securing of the pull-out element is effected by means of the restoring force of the storage element.A further development of the invention provides that the pull-out element is present as a pull-out frame or as a pull-out strip. The pull-out element can thus be frame-shaped or strip-shaped. The pull-out frame is understood to mean an embodiment of the pull-out element in which the latter has a plurality of spars which engage around a central opening of the pull-out element. For example, the extension frame is quadrangular, in particular rectangular. The pull-out frame is preferably mounted in such a way that it engages around the base plate in the first position, that is to say the base plate engages into the opening bounded by the spars. This achieves a particularly compact configuration of the depositing device.Alternatively, the pull-out element is present as a pull-out strip. This is understood to mean a configuration of the pull-out element in which said pull-out element has a rectangular cross section in a plane defined by two directions perpendicular to one another and has an extent in a direction perpendicular to said directions which is significantly greater than the extent in each of the other directions, for example by a factor of at least 10, at least 25 or at least 50.A further development of the invention provides that the axis of rotation is oriented parallel to the base plate and / or the displacement path is angled with respect to the base plate. The base plate has a longitudinal central plane which is arranged centrally in the directions of its greatest extent. The axis of rotation is, for example, completely accommodated in this longitudinal center plane or is arranged at least parallel thereto. Additionally or alternatively, the displacement path is angled with respect to the base plate, in particular again with respect to its longitudinal central plane. This means that the displacement path encloses an angle with the base plate or the longitudinal center plane which is greater than 0° and less than 180°. The angle is preferably at least 60° and at most 120°, at least 75° and at most 105° or approximately or exactly 90°. Again, such a configuration achieves a high level of operating comfort.A further development of the invention provides that the pull-out element is mounted via a damper and / or can be fixed in at least one of the positions by means of a locking mechanism. The damper is arranged and configured in such a way that it brakes or dampens a displacement of the pull-out element from the direction of the second position in the direction of the first position and / or vice versa. This prevents sudden snapping back of the pull-out element due to the restoring force caused by the storage element. Additionally or alternatively, the locking is present. This serves to fix the pull-out element in the at least one position, preferably at least in the first position and / or at least in the second position, but particularly preferably both in the first position and in the second position. This realizes the aforementioned comfortable operation of the storage device.The invention further relates to a motor vehicle having a storage device, in particular a storage device according to the embodiments within the scope of this description. It is provided here that the storage device has a base plate, an extraction element mounted displaceably with respect to the base plate and a flexible storage element which is fastened on the one hand to the base plate and on the other hand to the extraction element, so that the storage element is arranged between the base plate and the extraction element in a first position of the extraction element and forms at least one storage surface in a second position of the extraction element.It is furthermore provided that the pull-out element is mounted with respect to the base plate in such a way that the restoring force produced by the depositing element holds the pull-out element in the second position corresponding to an over-center point.The advantages of such an embodiment of the motor vehicle or of the storage device have already been pointed out. Both the motor vehicle and the storage device can be further developed according to the explanations within the scope of this description, so that reference is made to these in this respect. As already mentioned, the motor vehicle has an interior trim element, for example the dashboard, the seat and / or the door. On the interior fitting element, for example therefore on at least one of the mentioned elements, the depositing device or one of a plurality of depositing devices is arranged or fastened. In particular, only the base plate is fastened to the interior fitting element, whereas the pull-out element and the storage element can be displaced at least temporarily.The features and combinations of features described in the description, in particular the features and combinations of features described in the following description of the figures and / or shown in the figures, can be used not only in the respectively specified combination but also in other combinations or alone without departing from the scope of the invention. Embodiments are therefore also to be considered as encompassed by the invention which are not explicitly shown or explained in the description and / or the figures, but which emerge from the explained embodiments or can be derived from them.The invention is explained in more detail below with reference to the exemplary embodiments shown in the drawing, without any restriction of the invention being effected. The following shows: FIG. 1 shows a schematic illustration of a region of a motor vehicle having a storage device in a first embodiment, wherein an extraction element of the storage device is arranged in a first position, FIG. 2 shows a schematic illustration of the region of the motor vehicle, with the storage device in its first embodiment, wherein the pull-out element is arranged in a second position different from the first position, and FIG. 3 shows a schematic illustration of an area of the motor vehicle with a storage device according to a second embodiment.FIG. 1 shows a schematic illustration of a region of a motor vehicle 1, more precisely of a seat 2 of the motor vehicle 1. the seat 2 has a seat cushion 3 with a seat surface 4 and a backrest 5. The storage element 9 is arranged between the base plate 7 and the pull-out element 8, i.e. is fastened on the one hand to the base plate 7 and on the other hand to the pull-out element 8. In the exemplary embodiment shown, both the pull-out element 8 and the depositing element 9 engage around the base plate 7.The support element 9 is composed, for example, of a plurality of regions 10, which are connected in particular rigidly and via elements 11 with lower rigidity or higher elasticity, which are not visible here. These regions 10 are arranged between the regions 10 in the shown first position of the pull-out element 8 and are concealed by them.FIG. 2 again shows the schematic representation of the motor vehicle 1 with the storage device 6 in the first embodiment, wherein the pull-out element 8 is now arranged in a second position. The displacement of the pull-out element 8 from the first position into the second position takes place according to the arrow 12 as a rotational movement about an axis of rotation 13, which is arranged here, for example, above the base plate 7. Of course, the axis of rotation 13 can also be arranged differently from that shown, for example below the base plate 7.It can be seen that the storage device 6 unfolds as a result of the displacement of the pull-out element 8 from the first position into the second position, wherein the elastic regions 11 present between the regions 10 are clamped. This forms a storage surface 14 for depositing at least one object. The storage surface 14 is additionally bounded by walls 15 which are likewise formed by the storage element 9 and which together with the storage surface 14 and the base plate 7 create a receiving space 16. The walls 15 serve as a boundary for the storage surface 14 and prevent, for example, the object deposited on the storage surface 14 from falling down.FIG. 3 shows a schematic illustration of the motor vehicle 1, again with the seat 2, on the backrest 5 of which the storage device 6 is present in a second embodiment. The depositing element 9 is again composed of a plurality of regions 10 and 11 which are arranged alternately and are only partially marked here. The regions 10 and 11 are combined in a plurality of groups 17 which are arranged next to one another and are fastened in each case to the base plate 7 and to the pull-out element 8. Each of the groups comprises a plurality of regions 10 and a plurality of regions 11. Only a part of the groups 17 is identified.With the described configuration of the motor vehicle 1 or of the storage device 6 for the motor vehicle 1, a storage device 6 that can be easily handled is provided, which is also of simple construction and can be produced cost-effectively. The design of the storage element 9 which is flexible at least in certain regions also has a high level of safety inherent to it without further measures, so that there is no risk of injury to an occupant of the motor vehicle 1 even in the event of an accident of the motor vehicle 1.LIST OF REFERENCE CHARACTERS:1 Motor vehicle 2 seat 3 seat cushion 4 seat surface 5 backrest 6 storage device 7 base plate 8 extension element 9 storage element 10 region 11 region 12 arrow 13 axis of rotation 14 storage surface 15 wall 16 receiving space 17 group
