Description

[0001] The invention relates to a storage device with the aid of which a parcel shelf bridging a distance between a rear window and a rear seat of a motor vehicle can be pivotally stored in the motor vehicle.

[0002] DE 10 2011 120 090 A1 discloses a parcel shelf that is pivotably mounted in a bearing groove in a side panel via laterally projecting bearing pins. Each bearing groove extends essentially horizontally, so that the bearing pin can be threaded into one end of the bearing groove facing in the direction of travel and is pivotally received in its designated end position at the opposite end of the bearing groove. In this case, the parcel shelf protrudes slightly beyond the position of the bearing pin in the direction of travel.

[0003] From US 4 148 516 A, EP 0 283 363 B1 and FR 2 641 506 A1 it is known to clip a bearing bolt protruding laterally from a parcel shelf in a vertical direction into a bearing receptacle of a side wall panel.

[0004] There is a constant need to increase the durability of automotive components, even in the event of improper handling.

[0005] It is the object of the invention to show measures which enable a high durability of motor vehicle components, in particular a parcel shelf arrangement, even in the event of incorrect handling.

[0006] The object is achieved according to the invention by a storage device having the features of claim 1. Preferred embodiments of the invention are specified in the subclaims, which may each individually or in combination represent an aspect of the invention.

[0007] According to the invention, a bearing device for pivotably supporting a parcel shelf in a side wall panel of a motor vehicle is provided, comprising a bearing block connectable to the parcel shelf and a bearing pin for insertion into a bearing groove of the side wall panel so as to be rotatable about a horizontal bearing axis, wherein the bearing pin is movable relative to the bearing block at least in a partial area with a movement component in the vertical direction, and the bearing pin is locked to the bearing block in a designated use position against relative movement to the bearing block up to a predefined limit force.

[0008] If the bearing pin threaded into the bearing groove is mistakenly not positioned all the way to its end position within the bearing groove, which determines the correct positioning of the bearing axis in the direction of travel, it may happen that a part of the parcel shelf protruding in the direction of travel strikes the material forming the bearing groove when the parcel shelf is pivoted. In this case, the parcel shelf pivots further about an axis running along the contact point between the parcel shelf and the material of the bearing groove. This creates a lever arm between the contact point and the bearing pin inserted in the bearing groove, whereby the bearing pin is pressed against the bearing groove with a correspondingly high force. This force is essentially horizontal.If this force exceeds the predefined limit force, the locking of the bearing pin to the bearing block can be released, allowing the bearing pin to move relative to the bearing block from the designated use position. This prevents the bearing pin from breaking off. The relative movement of the bearing pin relative to the bearing block can, for example, cause the bearing pin to move sideways out of the bearing groove and / or become separated from the bearing block. This immediately makes it obvious to a person pivoting the parcel shelf that a malfunction has occurred.In this situation, the person can re-engage the bearing pin with the bearing block in the designated use position by reversing the previous relative movement and then thread the bearing pin back into the bearing groove. In this case, the bearing pin is more likely to be positioned within the bearing groove to its final position. In particular, the force required to thread and / or engage the bearing pin into the bearing groove is significantly lower than the limit force required to disengage the bearing pin from the bearing block, so that even with a very high disengagement / misuse force, a customer-friendly engagement force is simultaneously achieved when inserting the parcel shelf into the side panel.Due to the different directions of movement when threading in on the one hand and when disengaging on the other, this can easily be achieved by independently designing the forces for threading / engaging on the one hand and disengaging / misuse on the other. In the designated position of use, the bearing pin can enable the intended pivoting of the parcel shelf after reaching the end position in the bearing groove of the side wall panel. Because the bearing pin is relatively movable but locked to the bearing block, if the bearing device is not positioned correctly in the bearing groove, the bearing pin can overcome the locking and avoid the occurring loads before the bearing pin can break off. This means that a high durability of motor vehicle components, in particular a parcel shelf assembly, is enabled even in the event of incorrect handling.

[0009] The bearing block can be fastened, in particular, to a parcel shelf using suitable connecting means. This allows one bearing device to be fastened to a left-hand side of the parcel shelf and another bearing device to a right-hand side of the parcel shelf, in particular to an underside of the parcel shelf pointing downwards in the direction of gravity, wherein the respective bearing bolts of the bearing device are arranged essentially coaxially to one another. The parcel shelf can thus be pivoted about the bearing axis, which runs essentially horizontally and essentially perpendicular to the direction of travel of the motor vehicle. The parcel shelf can, for example, be connected to a tailgate of the motor vehicle, so that when the tailgate is opened, the parcel shelf is automatically pivoted with it, in particular to create an enlarged access opening for a trunk provided in the rear of the motor vehicle.

[0010] The limit force above which the locking of the bearing pin with the bearing block can be released is selected in particular such that the bearing pin is not inadvertently released when the bearing device is inserted into the bearing groove when a parcel shelf arrangement is used which has a parcel shelf and bearing devices fastened to the parcel shelf. The limit force can be higher than the assembly forces acting on the bearing pin when the bearing pin is threaded into the bearing groove and moved to its end position in the bearing groove with a force which may act obliquely to the course of the bearing groove. It can be taken into account here that the bearing groove can in particular have a taper which forms a press fit with the bearing pin and past which the bearing pin must be moved with a corresponding force in order to reach the end position.The tapered section allows the bearing pin to be held in its final position and / or prevents rattling of the parcel shelf. At the same time, the limit force is selected such that the locking mechanism is released before the bearing pin breaks and / or detaches from the bearing block. The limit force F. G For example, 30 N ≤ F G ≤ 100 N, especially 40 N ≤ F G ≤ 80 N and preferably 50 N ≤ F G ≤ 60 N.

[0011] In particular, the bearing pin is pivotally mounted on the bearing block about a pivot axis running transversely to the bearing axis, wherein the bearing pin is locked to the bearing block to prevent pivoting about the pivot axis from the designated use position up to the predefined limit force. In the designated use position of the bearing pin, the limit force can run essentially perpendicular to a plane spanned by the bearing axis and the pivot axis. If the limit force is exceeded due to incorrect use, the retaining pin can, for example, fold downwards away from the parcel shelf. This allows the bearing pin in particular to move out of the bearing groove and lift the parcel shelf, which is connected via the bearing block, from the side wall paneling forming the bearing groove. This can prevent damage. The bearing pin can then be folded back into its designated use position and threaded back into the bearing groove.

[0012] The bearing pin preferably has a pivot pin extending transversely to the bearing axis, wherein the pivot pin is inserted in at least one bearing receptacle of the bearing block in a relatively rotatable manner. The pivot pin inserted in the bearing receptacle can thus form a joint that enables the pivoting of the bearing pin relative to the bearing block. The pivot pin is in particular formed integrally with the bearing pin.

[0013] Particularly preferably, the bearing support of the bearing block is open toward a free end of the bearing pin, which protrudes from the bearing support in the designated use position. The pivot pin can thus be easily inserted into the bearing support by a relative movement of the bearing pin relative to the bearing block along the bearing axis. At the same time, it is possible for the bearing pin to strike the front end when threaded into the bearing groove, thereby pressing the pivot pin into the bearing support. This ensures correct and secure installation of the pivot pin in the bearing support, even if the pivot pin was not previously inserted far enough into the bearing support.

[0014] In particular, the bearing pin is guided transversely to the bearing axis on the bearing block, in particular via a tongue and groove connection, so as to be displaceable along a disengagement direction, wherein the bearing pin is locked to the bearing block to prevent displacement along the disengagement direction from the designated use position up to the predefined limit force. The limit force can run essentially parallel to the disengagement direction, in particular essentially vertically. If the limit force is exceeded due to incorrect use, the retaining pin can, for example, be pushed downwards away from the parcel shelf. This allows the parcel shelf, which is connected via the bearing block, to lift off the side panel forming the bearing groove, while the retaining pin still remains in the bearing groove. Damage can thus be avoided.The parcel shelf can then be pushed back until the bearing pin has engaged in its designated position of use, and then the bearing pin can be pulled into the end position within the bearing groove of the side panel using the parcel shelf.

[0015] It is also possible to provide multiple locking mechanisms connected in series. This allows, for example, a linear movement of the retaining pin along the disengagement direction above a first limit force, and a pivoting movement of the retaining pin around the pivot axis above a second limit force exceeding the first limit force. The retaining pin can thus perform a multi-stage movement in the event of misuse.

[0016] Preferably, the bearing pin has a locking pin extending transversely to the bearing axis, with the locking pin being locked to the bearing block. The locking pin increases the surface area for locking to the bearing block. This allows for a correspondingly high limit force for locking. This prevents unnecessary release of the locking mechanism.

[0017] Particularly preferably, the bearing block has a locking element that is locked to the bearing pin, wherein the locking element is designed as a retaining clip, retaining spring, or pre-tensioned locking ball. The locking element can implement the intended limit force for releasing the locking. With the aid of a retaining spring, a purely frictional locking can be provided by clamping forces. The retaining clip can enable a positive connection with the bearing pin, wherein the holding parts of the retaining clip can spring away when the limit force is reached in order to cancel the positive connection and release the bearing pin. The locking ball can be pressed into a corresponding recess by a spring, in particular designed as a helical spring, wherein the spring force of the spring is aligned in particular substantially perpendicular to the relative movement of the bearing pin relative to the bearing block after the limit force has been overcome.When the limit force is reached, the locking ball can be pushed out of the recess against the spring force of the spring, thereby breaking the positive locking and releasing the bearing pin.

[0018] In particular, the bearing pin has a bearing head at a free end protruding from the bearing block that can be inserted into the bearing groove of the side panel. The bearing head is made of a different material than the bearing pin. The bearing head can, in particular, have a larger diameter than the rest of the bearing pin. The bearing head can, in particular, enable a friction-reduced material pairing with the bearing groove, thus enabling a smooth pivoting movement of the parcel shelf.

[0019] The invention further relates to a parcel shelf arrangement for covering a gap between a rear window and a rear seat of a motor vehicle, comprising a parcel shelf that can be connected in particular to a tailgate, a first bearing device connected to the parcel shelf, which can be designed and developed as described above, for pivotably supporting the parcel shelf in a first bearing groove in a first side wall panel of a motor vehicle, and a second bearing device connected to the parcel shelf, which can be designed and developed as described above, for pivotably supporting the parcel shelf in a second bearing groove in a second side wall panel of the motor vehicle, wherein in particular the first bearing device and / or the second bearing device are fastened to the parcel shelf via a fastening mandrel having locking lugs, in particular dowels and / or expansion dowels.In particular, the bearing block and / or the fastening pin are glued to the parcel shelf. Due to the relatively movable bearing pin of the respective bearing device, which is locked to the bearing block, if the bearing device is not properly positioned in the bearing groove, the bearing pin can overcome the locking and avoid the resulting loads before the bearing pin can break off, thus ensuring a high level of durability for motor vehicle components, especially the parcel shelf assembly, even in the event of incorrect handling. The locking lugs of the fastening pin enable a particularly stable connection between the bearing device and the parcel shelf. This can prevent the bearing device from detaching from the parcel shelf below the limit force.

[0020] The invention further relates to a motor vehicle rear end for a motor vehicle with a first side wall panel having a first bearing groove, a second side wall panel having a second bearing groove and a parcel shelf arrangement pivotably mounted in the first bearing groove and the second bearing groove, which can be designed and developed as described above, wherein the first bearing groove for threading the bearing bolt of the first bearing device and the second bearing groove for threading the bearing bolt of the second bearing device extend transversely to the bearing axis, in particular substantially horizontally.Due to the relatively movable bearing pin, which is locked to the bearing block, if the bearing device is not positioned correctly in the bearing groove, the bearing pin can overcome the locking and avoid the occurring loads before the bearing pin can break off, thus enabling a high level of durability of motor vehicle components, in particular the parcel shelf assembly, even in the event of incorrect handling. In particular, the force required to thread and / or lock the respective bearing pin into the corresponding bearing groove is significantly lower than the limit force required to disengage the bearing pin from the bearing block, so that despite a very high disengagement / misuse force, a customer-friendly locking force is simultaneously achieved when inserting the parcel shelf into the side panel.Due to the different directions of movement during threading on the one hand and disengagement on the other, this can easily be achieved by independently designing the forces for threading / engagement on the one hand and disengagement / misuse on the other.

[0021] The invention will be explained below by way of example with reference to the accompanying drawings using preferred embodiments, wherein the features presented below can represent an aspect of the invention both individually and in combination. They show: Fig. 1: a schematic sectional view of part of a motor vehicle rear with a parcel shelf arrangement in a first position, Fig. 2: schematic sectional view of the rear of the vehicle from Fig. 1 with the parcel shelf arrangement in a second position, Fig. 3: a schematic bottom view of a first embodiment of a bearing device for the parcel shelf arrangement from Fig. 1 and Fig. 2, Fig. 4: a schematic side view of the storage facility from Fig. 3, Fig. 5: a schematic sectional side view of a second embodiment of a bearing device for the parcel shelf arrangement of Fig. 1 and Fig. 2, Fig. 6: a schematic bottom view of the storage facility from Fig. 5, Fig. 7: a schematic sectional side view of a third embodiment of a bearing device for the parcel shelf arrangement of Fig. 1 and Fig. 2, Fig. 8: a schematic bottom view of the storage facility from Fig. 7, Fig. 9: a schematic bottom view of a parcel shelf arrangement for the rear of a motor vehicle from Fig. 1 and Fig. 2, Fig. 10: a schematic sectional side view of a first embodiment of the parcel shelf arrangement from Fig. 9 and Fig. 11: a schematic sectional side view of a second embodiment of the parcel shelf arrangement from Fig. 9.

[0022] The Fig. 1 and Fig. The rear end of the motor vehicle 10 shown in Figure 2 has a side wall panel 12 in which a bearing groove 14 is formed. A parcel shelf assembly 16 can be pivotally received in the bearing groove 14. For this purpose, the parcel shelf assembly 16 has a parcel shelf 18 and a bearing device 20 with a bearing pin 22 inserted in the bearing groove 14. A bearing device 20 can be provided with the parcel shelf 18, in particular on the left side and on the right side, which cooperates with a bearing groove 14 of the respective associated left or right side panel 12. During assembly, the respective bearing pin 22 can be threaded into the associated bearing groove 14 ( Fig. 1) and along the bearing groove 14 past a taper 24 to an end position within the bearing groove 14 ( Fig. 2), in which a proper pivoting movement of the parcel shelf 18 about a bearing axis 26 running through the longitudinal extension of the bearing pin 22 is realized. If, due to incorrect use, the bearing pin 22 is not rotated to the Fig. 2, but before the taper 24, for example in the position shown in Fig. 1, high forces can act on the bearing bolt 22 when the parcel shelf 18 is pivoted due to the leverage effect.

[0023] To prevent the bearing pin 22 from breaking off in the event of misuse, the bearing pin 22 can be secured as shown in Fig. 3 and Fig. 4, for example, be pivotably mounted on a bearing block 28 of the bearing device 20. For this purpose, a pivot pin 30 can protrude perpendicular to the bearing axis 26, which pivot pin 30 is inserted into a bearing receptacle 32 that is open towards the free end of the bearing pin 22 in the designated use position shown, and which enables a pivoting movement of the bearing pin 22 about a pivot axis 34. In the designated use position shown, the bearing pin 22 is inserted and locked in a locking element designed as a holding clip 36. If, due to incorrect use, such high forces act on the bearing pin 22 that a predefined limit force is exceeded, the bearing pin 22 can release the locking mechanism and, by pivoting about the pivot axis 34, can be released from the holding clip 36 before the bearing pin 22 and / or the holding groove 14 can be damaged and / or torn off.Furthermore, the bearing pin 22 can have a bearing head 38 which can be inserted into the bearing groove 14 and which, for example, provides a suitable material pairing with the material of the bearing groove 14.

[0024] At the Fig. 5 and Fig. 6 illustrated embodiment of the bearing device 20, the bearing pin 22 can be compared to the embodiment shown in Fig. 3 and Fig. In the embodiment of the bearing device 20 shown in Figure 4, locking pins 40 protrude perpendicularly to the bearing axis 26 and run essentially parallel to the pivot axis 34. Each locking pin can be locked with a locking element configured as a retaining clip 36 until the limit force is reached. The limit force for releasing the locking can thereby be increased. Furthermore, the retaining pin 22 is positioned largely countersunk into the material of the bearing block 28 in the designated use position.

[0025] At the Fig. 7 and Fig. In the embodiment of the bearing device 20 shown in Figure 8, the bearing pin 22 is not pivotably locked to the bearing block 28, but rather displaceably. For this purpose, the bearing pin 22 can be guided on the bearing block 28 via a tongue and groove connection 42 in the manner of a dovetail connection, allowing linear movement along a disengagement direction 44 running essentially perpendicular to the bearing axis 26. Sufficient locking up to the limit force can be achieved by a locking element designed as a preloaded locking ball 46. For this purpose, the locking ball 46 is pressed into a corresponding recess in the bearing pin 22 by a spring force of a spring 48 acting along the bearing axis 26. When the limit force is reached, the bearing pin 22 can press the locking ball into the bearing block 28 against the spring force of the spring 48 designed as a helical spring and can be displaced in the locking direction 44 relative to the bearing block 28 before damage can occur.

[0026] As in Fig. As shown in Figure 9, the bearing device 20 can be connected to the parcel shelf 18 by fixing the bearing block 28 to the parcel shelf 18, for example, at four points via fastening pins 50. As shown in Fig. As shown in Figure 10, the respective fastening pin 50 can have locking lugs 52 that can block the withdrawal of the fastening pin 50 from the parcel shelf 18. The locking lugs 50 can in particular dig into the material of the parcel shelf 18. The fastening pin 50 can in particular be designed in the manner of a dowel. As shown in Fig.As shown in Figure 10, the fastening mandrel 50 can also be designed in the manner of an expansion dowel. In this case, a particularly metallic expansion pin 54 or an expansion screw can be driven into the fastening mandrel 50, whereby the locking lugs 52 are pressed laterally into the material of the parcel shelf 18 and form a positive connection. Additionally, the fastening mandrel 50 and / or the bearing block 28 can be glued to the parcel shelf.
