DETAILED DESCRIPTION

[0038] FIGS. 1A to 1D show a device V for load securement designed according to the invention for a rear-side loading space of a motor vehicle. The device V in particular includes a securing element in the form of a securing mat 2 that is adjustable in a power-operated way between a position of non-use and a position of use. In its position of non-use, this securing mat 2 is accommodated in a receptacle A on a loading area L in a stretched and hence flat condition. From this receptacle A, the securing mat 2 is extendable substantially along the vertical into an extended position of use.

[0039] In the position of use, the securing mat 2 in particular can take a loading position, as it is shown in FIG. 1D, so that below the securing mat 2 moved upwards loaded goods can be arranged on the loading area L. Since the securing mat 2 includes a flexible textile part 20 that on lowering of the securing mat 2 into a securing position can be stretched tightly over the objects arranged on the loading area L, these objects forming the loaded goods are secured against slippage on the loading area L via the securing mat 2.

[0040] To extend the securing mat 2 into its position of use and to adjust the same between a loading position and a securing position, in which the securing mat 2 is stretched tightly over objects arranged on the loading area L in order to hold the same in a defined position on the loading area L, a motorized adjusting device is provided, which is not shown here in all its details. This adjusting device in particular includes a plurality of adjusting elements in the form of link chains 22a to 22d. In the present case, four self-stiffening link chains 22a, 22b, 22c and 22d are provided, which each engage an end piece 21a to 21d of a support frame 21 of the securing mat 2. Between this support frame 21 the flat textile part 20 is stretched. By extending the self-stiffening link chains 22a to 22d from four associated (corner) openings in thehere rectangularloading area L, of which merely 3 openings O1 to O3 are shown in the attached FIGS. 1A to 1D, the support frame 21 can be lifted and lowered and the possibly multilayer textile part 20 thereby can be stretched tightly over loaded goods arranged on the loading area L, when it is adjusted from the loading position into its securing position.

[0041] The link chains 22a to 22d for example are deflected below the respectively associated opening in order to be accommodated in the most space-saving way. The link chain 22a to 22d elastic per se to this end stiffens on extension from the respectively associated opening via chain links positively engaging into each other, as is described for example in the German Patent Application DE 10 2014 218 256.5.

[0042] To protectively cover the securing mat 2, if necessary, in its position of non-use, in which it is stretched and hence accommodated in the receptacle A so as to extend over a large part of the loading area L, and to avoid that objects must be placed directly on the securing mat 2, the device V here is equipped with a floor cover 1. This floor cover 1 in the present case completely covers the securing mat 2 accommodated in the receptacle A, when the same is present in its position of non-use. In addition, the floor cover 1 in the present case is formed such that it can be opened and closed in a power-operated way via a drive unit comprising at least one electromotive, pneumatic and/or hydraulic drive motor.

[0043] In the present case, the floor cover 1 is equipped with a plurality of pivotally mounted covering elements in the form of covering plates 10, 11, 12 and 13. These covering plates 10 to 13 define a multipart loading floor which in the closed position of the floor cover 1 extends above the loading area L and above the securing mat 2 and provides for depositing objects in the loading space without damaging the retracted securing mat 2. The individual covering plates 10 to 13 are comparatively stiff and possibly provided with one or more support domes on their underside facing the securing mat 2 present in its position of non-use and the loading area L for an additional stiffening and/or additional support.

[0044] Two covering plates 10, 11 and 12, 13 each are articulated to each other via a plurality of rotary plate joints in the form of plate hinges 15. One pair of covering plates 10, 11 and 12, 13 each can thereby be folded together in the manner of a folding shutter. The covering plates 10, 11 or 12, 13 articulated to each other thus can be folded onto each other. In addition, one first (left or right) outer covering plate 10 or 13 each is articulated to a component firmly installed in the loading space via a plurality of rotary joints in the form of hinges 14 and thus pivotally mounted thereon. In this way, the total of four covering plates 10 to 13 of the floor cover 1 can be folded up if necessary in order to provide for an extension of the underlying securing mat 2 and gain access to the loading area L.

[0045] When folding up the floor cover 1, two covering plates 10 and 11 or 12 and 13 each are swiveled open to the left or right, i.e. in the mounted condition in the direction of a left or right wheelhouse, and folded onto each other. In the condition folded up, the two pairs of covering plates 10, 11 and 12, 13 face each other along a vehicle transverse axis and extend substantially along the vertical, i.e. in the present case each are rotated by about 90 with respect to their respective position in the closed condition of the floor cover 1.

[0046] For the defined and preferably power-operated adjustment of the covering plates 10 to 13 of the floor cover 1, the respectively inner covering plates 11 and 12 are shiftably held on a component firmly installed in the loading space, preferably on a component of the device V firmly installed in the loading space. Preferably, in the region of a longitudinal edge of a covering plate 11 or 12 each facing the opposed covering plate 12 or 11, a traveling part, possibly equipped with an additional coupling element for the connection to the respective covering flap 11 or 12, is shiftably mounted. Such traveling part is translatorily shiftable transversely to the axes of rotation defined by the hinges 14 and 15, for example via a spindle drive or a Bowden cable drive, and hence is configured and equipped to transmit an adjusting force to the respective inner covering plate 11 or 12 of a pair of foldable covering plates 10, 11 or 12, 13. An adjusting force that acts in the direction of the axis of rotation of the respectively associated outer (second) covering plate 10 or 13 leads to an erection of the two covering plates 10, 11 and 12, 13 articulated to each other and to these covering plates 10, 11 and 12, 13 folding onto each other in pairs, until the covering flaps 10, 11 and 12, 13 at least partly are put up in pairs to such an extent that the securing mat 2 can be extended.

[0047] For torque and speed adaptation, a preferably single-stage spur-gear transmission, a worm gear and/or a toothed belt can be provided in the associated drive unit for the power-operated adjustment of the floor cover 1. Alternatively or in addition, at least one spring element can be provided to support an adjusting movement for opening or closing the floor cover.

[0048] In the illustrated exemplary embodiment of FIGS. 1A to 1D a component of the device V firmly installed in the loading space is formed by a loading floor insert E. This loading floor insert E forms the receptacle A. Furthermore, not only the non-illustrated drive unit can be mounted on the same below the loading area L, but also slotted guides for specifiying a defined path of adjustment transversely to the axes of rotation defined by the hinges 14 and 14 for folding the covering flaps 10 to 13 open and closed as well as parts of an adjusting device comprising the link chains 22a to 22d.

[0049] The loading floor insert E in the present case includes four edge portions R1 to R4 bordering the receptacle A and protruding raised with respect to the receptacle A. On the front and rear edge portions R1 and R3 each extending transversely, the respective inner covering flaps 11 and 12 are shiftably guided. On the two lateral, outer edge portions R2 and R4 the one outer covering flap 10 or 13 each is pivotally mounted.

[0050] The device V can be of modular construction with the loading floor insert E, so that a prefabricated modular unit is formed by means of the loading floor insert E on which the covering plates 10 to 13 already are pivotally mounted, the securing mat 2 is accommodated in the receptacle A, and the adjusting device with the link chains 22a to 22d for the securing mat 2 and the drive unit for the power-operated adjustment of the covering plates 10 to 13 are operable and pre-testably mounted.

[0051] Instead of laterally folding away two pairs of covering plates 10, 11 and 12, 13 in order to open a floor cover 1, it can also be provided to swivel open or fold up an individual covering plate or a plurality of covering plates articulated to each other merely towards one side. This includes in particular a process of swiveling open or folding up, in which the respective covering plate in the open position of the floor cover 1 then is arranged vertically to the rear seat bench or to a right or left wheelhouse of the vehicle. In the case of more than two covering plates, which can be folded onto each other for opening the floor cover, the same can be foldable onto each other in the manner of an accordion.

[0052] In another design variant the covering elements for covering the securing mat 2 in their position of non-use are configured in significantly larger numbers and narrower, in the manner of slats. For opening the floor cover towards the side or towards the vehicle front (in the direction of a rear seat), the slats then articulated to each other can be wound up in order to open the floor cover 1.

[0053] By means of an electronic control unit, an adjusting movement for opening and/or closing the floor cover 1 moreover can be controlled, for example after occurrence of a manually triggered operating event and/or in response to a signal from the on-board electronic system of the vehicle.

[0054] FIGS. 2, 3A to 3C, 4 and 5A to 5B illustrate a variant of a device V according to the invention, which in combination with a securing element 2 can be combined corresponding to the design variant of FIGS. 1A to 1D, but which also can easily be utilized without such a securing element 2. In the variant of FIGS. 2, 3A to 3C, 4 and 5A to 5B components corresponding with the variant of FIGS. 1A to 1D are designated with identical reference numerals. Moreover, the variant of FIGS. 2, 3A to 3C, 4 and 5A to 5B shows details of a drive unit 3 that likewise can be used in a device V according to FIGS. 1A to 1D.

[0055] The device V of FIGS. 2 to 5B in correspondence with the design variant of FIGS. 1A to 1D explained above includes a floor cover 1 that is formed by a plurality of covering plates 10 to 13 of which covering plates 10, 11 and 12, 13 are articulated to each other. The respective outer covering plate 10 or 13 of a pair of covering plates 10, 11 or 12, 13 each is articulated to an edge portion R2 or R4, so that the covering plates 10 to 13 can be folded together and folded up in pairs in order to open the floor cover 1.

[0056] The drive unit 3 provided for the power-operated adjustment of the floor cover 1 in the present case among other things includes a drive motor 30 via which an adjusting force can be applied to the two respective inner covering plates 11 and 12 in order to open and close the floor cover 1. The drive motor 30 here is provided centrally at a front end, i.e. at an end facing a rear seat when the motor is accommodated in a rear-side loading space. Via a motor mount 300 the drive motor 30 is fixed to a guide rail 31 of the drive unit 3. The guide rail 31 in the present case forms a guide element of the drive unit 3 on which the inner covering plates 11 and 12 are longitudinally shiftably guided. To provide for a folding up of the covering plates 10 to 13 for opening the floor cover 1, the inner covering plates 11, 12 each are articulated to a traveling part in the form of a (driver) carriage 32.1 or 32.2 via a coupling element 110 or 120. This carriage 32.1 or 32.2 is translatorily shiftable along the guide rail 31. While the respective coupling element 110 or 112, as shown for example in FIG. 5B, is shiftably held on the guide rail 31, the respective carriage 32.1 or 32.2 is shiftably mounted on two threaded rods 33.1 and 33.2 of a spindle drive of the drive unit 3 which extend parallel to the guide rail 31. The threaded rods 33.1 and 33.2 thus form drive elements by means of which the carriages 32.1 and 32.2, in combination with a spindle nut 35 present per carriage, are moved along an axispreferably synchronously to each otherthat extends transversely to the rotational and hinge axes of the covering flaps 10 to 13. For opening and closing the floor cover 1, the carriages 32.1, 32.2 are driven via the drive motor 30 to perform a translatory adjusting movement in opposite directions of adjustment. The torque of the drive motor 30 is transmitted to the threaded rods 33.1 and 33.2 by means of a single-stage gearwheel transmission 36 of the drive unit 3. This gearwheel transmission 36 is arranged in the motor mount 300. FIG. 4 shows the mounting position of the gearwheel transmission 36 in the motor mount 300.

[0057] The threaded rods 33.1 and 33.2 arranged below the guide rail 31 are held on the motor mount 300 and on rod holders 34.1 and 34.2 spaced apart from each other. Approximately centrally between these rod holders 34.1 and 34.2 the drive motor 30 is placed via the motor mount 300. Both the rod holders 34.1 and 34.2 and the motor mount 300 here are mounted on the guide rail 31. The guide rail 31 thus also forms a cross-beam of the device Vpreferably as part of the loading floor insert Efor fixing and supporting the components of the drive unit 3.

[0058] On one side of the guide rail 31, there can also be held a control device 4, as control unit of the device V, for controlling the adjusting movement of the covering plates 10 to 13. The electronic control system provided by means of the control device 4 can contain an overcurrent detection to safeguard a reliable operation.

[0059] At a rear end of the loading space (in the region of a front loading edge LK) two electric actuation keys 6 of the device V are provided in the present case. A desired opening or closing movement of the floor cover 1 thereby can manually be triggered by a user in the loading space itself. A triggered adjusting movement of the carriages 32.1, 32.2 is stopped automatically upon reaching one of the two possible end positions, which corresponds with a completely open or completely closed condition of the floor cover 1. For stopping automatically, the drive unit 3 in the present case includes a plurality of switches 5a, 5b and a contactor 5c, which upon contact of a contactor 5c with a switch 5a or 5h generate a signal for the defined switching off of the drive motor 30. In the design variant of FIGS. 2 to 5B limit switches 5a and 5b for a carriage 32.1 or 32.2 therefor are provided on the one hand on a rod holder 34.1 or 34.2 and on the other hand on the motor mount 300 (cf. FIG. 5A). The respectively associated contactors 5c, which get in contact with these limit switches 5a or 5b in the respective end position, are provided on the carriage 32.1 or 32.2.

[0060] In particular the drive motor 30 and the carriages 32.1 and 32.2 of the drive unit 3, which are shiftable along the threaded rods 33.1 and 33.2, in the present case are arranged below a loading floor plane that is defined by the closed floor cover 1 and the covering plates 10 to 13 then juxtaposed. Since furthermore the components of the drive unit 3 then also are arranged at a distance from a front loading floor edge LK, which faces a tailgate opening of the vehicle, the drive unit 3 can be accommodated in a space-saving and inconspicuous way in the region of the rear-side loading space and preferably below a rear seat.

[0061] As can be seen in particular with reference to FIG. 2, means for securing the covering plates 11 and 12 to each other in the closed position can be provided on the coupling elements 110 and 120 of the two inner covering plates 11 and 12, which each are fixed to a corner of a covering plate 11 or 12. For example, the two coupling elements 110 and 120 interlock with each other when the floor cover 1 is closed, so that an arrestment 16 is defined thereby. Via this arrestment 16 an inadvertent displacement of the covering plates 11 and 12 with properly closed floor cover 1 is prevented. Only when a longitudinal displacement of the covering plates 11 and 12 by application of opposite adjusting forces is effected via the carriages 32.1 and 32.2 this arrestment 16 is released, so that the floor cover 1 can be opened.

[0062] The sequence of the adjusting movement on opening of the floor cover, which is shown in FIGS. 3A to 3C, substantially is identical to the variant of FIGS. 1A to 1D explained above. When the floor cover 1 corresponding to FIGS. 3C and 4 is completely opened and the covering plates 10 to 13 hence are folded onto each other in pairs, the underlying receptacle A is completely accessible and the loading area L is exposed.

[0063] Although in the design variant shown here the loading area L also is designed with openings (of which the openings O1 and O2 are shown in FIG. 3C) such that a securing element in the form of the securing mat 2 placed in the receptacle A can be extended by means of the link chains 22a to 22d, this is not absolutely necessary. The receptacle A of trough-like design also can be utilized for accommodating other objects. The receptacle A thus forms a kind of storage box which can be closed completely by the floor cover 1 adjustable in a power-operated way and can be opened upon request of a user without a manual intervention. As shown, this storage box can have a base area that occupies at least of the base area of the loading space. In principle, its base area can vary however depending on the size of the loading space and the case of application.

[0064] As can be seen with reference to the detail representation in FIG. 5B, a coupling element 110 (like also a mirror-symmetrical coupling element 120) in the present case includes two guide rollers 1101 and 1102. Via these guide rollers 1101 and 1102 the coupling element 110 (120) fixed to the respective covering plate 11 (or 12) on the one hand is shiftably mounted on the guide rail 31 and on the other hand connected to the associated carriage 32.1 (32.2).

[0065] Corresponding to FIG. 5B, an articulated connection is provided for the connection between the carriage 32.1 and the coupling element 110, via which the coupling element 110 can be entrained by the carriage 32.1 in order to adjust the same along the adjustment path specified by the guide rail 31 and a threaded rod 33.1. Via the articulated connection, the coupling element 110 also is pivotally held on the carriage 32.1 in order to permit a swivel movement of the coupling element 110 and hence of the covering plate 11 in the case of a longitudinal displacement of the carriage 32.1 along the threaded rod 33.1. In the present case, the articulated connection is realized via a drive pin 320, which protrudes from the carriage 32.1 transversely to the direction of extension of the threaded rod 33.1, and a bearing opening on the coupling element 110 for the guide roller 1102, into which this drive pin 320 engages. To avoid an abrupt impact on the coupling element 110 during the adjustment and in particular at the beginning of an adjusting movement and to prevent wedging between closed covering plates 10, 11 and 12, 13, there is no coaxial connection between the drive pin 320 and the coupling element 110, but a relative movement between the coupling element 110 and the associated carriage 32.1 deliberately is permitted via the bearing opening of the coupling element 110. Here, a combination of a short translational movement and a swivel movement of the coupling element 110 is permitted. In addition, the drive pin 320 preferably is provided with a damping material, for example coated with a damping material or connected to a separate damping element made of such a damping material.

[0066] The detail representation of FIG. 5B furthermore reveals a wedge-shaped tab on the coupling element 110, which in the open position of the floor cover 1 has a tapering end pointing in an opening direction along the threaded rod 33.1 (away from the motor mount 300). This tab has an oblique upper side facing the underside of the floor cover 1. When opening the floor cover 1, the retraction of the coupling element 110 below the stationary edge portion R2 thereby is facilitated.
