System for the detachable mechanical and electrical connection of components, in particular a seat removable from a motor vehicle, to a floor structure

The invention relates to a system for the releasable mechanical anchoring of a first stationary component, in particular a floor structure of a motor vehicle, including a first closure element fastened to the first component, to a second, movable component, in particular a seat that can be removed from a motor vehicle, including a second closure element fastened to the second component, and for the releasable electrical connection of a first plug part fastened to the stationary component, such as a plug, to a second plug part fastened to the movable component, such as a plug socket.

For removable vehicle seats or folding seat parts, such as backrests, it is known to use systems of various types with mechanical locking elements, by means of which the respective seat or seat part can be separated from the vehicle floor or another fixed base or releasably connected again, for example, with further (complementary) locking elements on the vehicle floor or the base. The locking elements enter into a mechanical operative connection with one another to establish the connected state of the components, in particular into at least a positive mechanical connection. It is also known to use lever mechanisms and/or lock latches as locking elements. "Electrification", i.e. the presence of an electrical circuit with corresponding plug parts, is generally dispensed with in standard motor vehicle designs in order to minimize costs.

to keep technical effort to a minimum.

However, a system for mechanical and also electrical connection of the type mentioned at the outset is known from DE 199 33 835 A1, which relates to a removable vehicle seat and a vehicle with such a seat. The motor vehicle seat described has anchors suitable for enabling the seat to be quickly attached and detached from the body of a vehicle by mounting and detaching movements, with at least one lower portion belonging to the seat moving along a predetermined direction, called the mounting direction. In order to equip the motor vehicle seat with more functions, it also has at least one electrical circuit that is supplied with power by means of an electrical connection device with two poles that is attached to the lower portion of the seat, this connection device being able to connect to an electrical connection device that is attached to the vehicle chassis or housing. By a movement in the mounting direction, the connection devices on the seat and on the chassis can be brought into mutual engagement and can be released from each other again by a movement in the opposite direction. The electrical circuit of such a seat can, for example, be used to supply seat heating or to detect seat occupancy.

In systems of this type, in which mechanical and electrical connections are formed between different components at the same time, there is a risk that the electrical connector parts may be damaged when removing or inserting a component that can be removed from the system. For example, in the case of electrified seats, you should always remember to remove the electrical connector(s) before removing the seat in order to prevent damage to the wiring harness when removing the seat.

The invention is based on the object of improving a system of the type mentioned at the outset with inexpensive means in such a way that its safety, in particular its installation safety, is increased while ensuring simple installation.

·

According to the invention, this is achieved by a securing device which is arranged and designed in such a way that, when a connection is present between the first plug part and the second plug part, it prevents the anchoring between the first component and the second component from being removed by blocking an anchoring connection between the first closure element and the second closure element, and when a connection is not present between the first plug part and the second plug part, it allows the anchoring between the first component and the second component to be removed by removing the blocking of the anchoring connection between the first closure element and the second closure element.

Such a safety device according to the invention thus simultaneously performs the functions of a sensor and a lock, so that the anchoring of the components can advantageously not be removed as long as the electrical connection is present. If such a system is used in a vehicle seat that can be removed from a motor vehicle and in particular installed and removed without tools, this results in greater assembly safety, as an incorrect sequence of the necessary assembly steps that could potentially lead to damage is ruled out from the outset.

In addition, it can also be advantageously provided that the securing device is arranged and designed in such a way that, if there is no anchoring connection between the closure elements, it prevents the establishment of a connection between the first plug part and the second plug part and, if such an anchoring connection is present, it allows the establishment of a connection between the first plug part and the second plug part.

The assumption of a (locking) safety position for the anchoring connection by the safety device can thus advantageously simultaneously release the electrical connection between the plug parts (allowing the connection to be broken), while the assumption of a safety position for the electrical connection (preventing the connection from being made) can simultaneously release the anchoring connection between the functional parts (allowing the connection to be broken).

allow adjustment of the anchorage).

The securing device can preferably be arranged on the movable component, so that an advantageously large free space remains on the stationary component, such as on the floor of a motor vehicle, after removal of the movable component, such as a seat.

The safety device according to the invention can be activated and deactivated in various ways, e.g. by interrupting or closing a circuit provided for this purpose, which includes the plug parts. In an advantageously simple embodiment, the safety device can also be designed to act purely mechanically, for example with a locking pawl (first functional part) which, when there is a connection between the first plug part and the second plug part, is elastically supported against one of the plug parts and which, when there is an anchoring connection between the locking elements, engages in a spring-loaded manner in a second functional part, whereby this engagement is canceled by a movement away (springing away) of the locking pawl when the connection between the first plug part and the second plug part is released. For this purpose, the second functional part can have a catch, such as a catch opening or a catch projection that can be gripped behind, for the first functional part of the safety device.

Furthermore, in the interests of simple manual operation, a handle for moving the second locking element can be mounted on the mobile component. This handle can be operatively connected to the safety device in such a way that movement of the handle for its operation is inhibited if the safety device blocks the removal of the anchoring connection between the first locking element and the second locking element - in other words: In concrete terms, a positive locking of the handle, e.g. of a removal lever, can take place as long as a seat is in electrical contact with the overall circuit of a vehicle. Conversely, it can also be prevented that a plug can be plugged in as long as there is no anchoring connection, which can also be achieved by clearly distinguishing the presence or

The closing and opening positions of the handle indicating the absence of the anchoring connection can be visually identified.

In an advantageous space-saving and assembly-friendly design, at least the second functional part and the safety device can be mounted in a common mounting channel on the mobile component.

Further advantageous features of the invention are contained in the subclaims and the following description.

The invention will be explained in more detail below using a preferred embodiment illustrated in the drawing. Figs. 1 to 3 each show a top view in various working positions of a system according to the invention for the detachable mechanical and electrical connection of components. Fig. 4 shows - also in top view - parts of an anchoring device for the first, stationary and the second, movable component, into which the system according to the invention can be advantageously integrated.

In the various figures of the drawing, the same parts are always provided with the same reference symbols, so that they are usually only described once.

In detail, the figures show the following main parts of the system: a first closure element S1 belonging to a first, unspecified component, a second closure element S2 belonging to a second, unspecified component, a first and a second plug part (plug 3 and plug socket 4), a first functional part 2 and a second functional part 5 of a securing device 2/5, a handle 6, a tension spring 7, wall parts 8a, 8b, 8c, 8d, 8e and a base 8f with an opening 8g of a mounting channel 8 and a pinion 9 with a suspension pin 10 for the tension spring 7. The functional parts 2, 5 of the securing device 2/5 are mounted in the area of the mounting channel 8.

The first closure element S1 forms an anchoring connection with the second closure part S2. The first functional part 2 is mechanically connected to the second functional part 5 of the safety device 2/5, in particular the two parts 2, 5 are locked together.

The first locking element S1 is designed as a bolt which projects vertically from the stationary component, e.g. from a motor vehicle floor structure, and which has a mushroom-shaped head S1a which sits on a shaft S1b and is partially overlapped by the second functional part 2 of the securing device 2/5 in the locking position.

The second closure element S2 can be arranged on the assembly channel 8 of the movable component or in the area of the assembly channel 8. In the embodiment shown, it is formed by at least a part of the assembly channel 8, namely by the base 8f and the opening 8g in the base 8f of the assembly channel 8, which cooperates in a form-fitting manner with the first closure element S1. The base opening 8g has a slot-like shape and is designed to be open at the edge in the assembly channel 8, so that the shaft S1b of the first closure element S1 can be introduced into the opening 8g by a sliding movement of the entire movable component with the assembly channel 8 against the direction indicated by the arrow Q in Fig. 1, while the head S1a of the first closure element S1 engages over the edges of the opening 8g.

As illustrated in Fig. 1, the securing device 2/5 is arranged and designed such that, when a connection is present between the first plug part 3 and the second plug part 4, it blocks a removal of the anchoring connection between the first closure element S1 and the second closure element S2.

Both functional parts 2, 5 of the safety device 5 are arranged on the movable component.

The first functional part 5 of the safety device is designed as a (substantially hook-shaped) part, in particular at one end, to be attached to a wall part 8a of the mounting channel

8, which, when the connection between the first plug part 3 and the second plug part 4 and the anchoring connection between the locking elements S1, S2 is present, is supported by a spring against one of the plug parts (plug 3) and at the same time engages with its free end in the second functional part 2. In order to make this possible, the second functional part 2 has a special shape, namely a catch 2b, such as a catch opening or a catch projection that can be gripped behind, for the first functional part 5. The spring effect on the first functional part 5 of the safety device 2/5 is advantageously not achieved by a separate spring, but by the functional part 5 itself being designed as a spring tongue.

The second functional part 2 is designed and mounted on the movable component, e.g. on a seat that can be removed from a motor vehicle, in such a way that it can be moved into the locking position shown by rotation. An end stop section 2a formed on the second functional part 2 - the function of which is explained in more detail below - overlaps the first closure element S1, in particular its mushroom head S1a.

In an alternative embodiment, it would also be possible to arrange the end stop section 2a lower than shown, so that it comes into contact with the shaft S1b and forms a positive connection with the first closure element S1, in that the end stop section 2a engages under the mushroom head S1a of the first functional part 1 and, if necessary, also engages around the shaft STb. In this case, the second functional part 2 could thus also serve as a closure element for forming a mechanical anchoring connection between the movable component and the stationary component. If the end stop section 2a of the second functional part 2 engages under the mushroom head SIa, as in the illustration shown, in which it is designed in the shape of a nose, it creates a positive anchoring connection with the first closure element S1, which is effective in a direction running perpendicular to the plane of the drawing. If such a positive anchoring connection is also to be effective in a direction lying in the plane of the drawing (parallel to the surface of the stationary component), the end stop section 2a would have to be designed in a hook-shaped manner so that it engages the shaft 1b

of the first functional part 1.

In the preferred embodiment shown, however, the system according to the invention is only intended as a subsystem (with the primary function of securing) in a higher-level anchoring device VE for the first stationary component and the second movable component. The fixation against movement in the direction of arrow Q is here - as will be explained below with reference to Fig. 4 - taken over by the higher-level anchoring device VE, which has a higher stability than the second functional part 2 and is effective at several points, so that a closing function (direct and complete mechanical anchoring connection with the first closure element S1) does not have to be taken over by the second functional part 2, but this in particular fulfills the function of a control for the securing device 2/5. This makes it possible to manufacture the second functional part inexpensively from a less rigid material, such as plastic.

In the locked state of the system according to the invention shown in Fig. 1, the plug 3 is firmly connected to the stationary component, e.g. to the motor vehicle floor structure, while the plug socket 4 is attached to the movable component, e.g. to the removable motor vehicle seat. "Firmly connected" is understood to mean that the plug 3 can also be located on a freely movable end of a cable laid (e.g. in or on the motor vehicle floor structure).

The handle 6 is operatively connected to the second functional part 2 in such a way that a movement of the handle 6 for its operation is inhibited when the safety device 2/5 in the position shown in Fig. 1 blocks a removal of the anchoring connection between the first closure element S1 and the second closure element S2.

In the embodiment shown, such an operative connection of the handle 6 with the second functional part 2 is achieved in particular by a special design of the second functional part 2 and the handle 6. This design includes

on the one hand, that the handle 6 is designed as a fork latch with a catch mouth 6a at an end facing the second functional part 2 and that on the other hand a locking element 2c is arranged on the second functional part 2, which interacts with the fork latch. When the second functional part 2 is blocked by the first functional part 5, this locking element 2c lies in the catch mouth 6a of the handle 6, and in fact it lies on a first flank 6b of the catch mouth 6a in such a way that the handle 6 cannot be moved - at least not in relation to the second component.

If a person attempts (improperly) to remove the mutual anchoring of the movable component and the stationary component by loosening the anchoring connection between the locking elements S1, S2 when an electrical connection is present, it will become clear to him during the (unsuccessful) attempt to operate the handle 6 (pulling in the direction of arrow P1 in Fig. 1) that the selected assembly sequence is incorrect. Incorrect operation during disassembly is therefore ruled out.

Fig. 2 shows the system according to the invention in a first state after the electrical plug connection between the plug parts 3, 4 has been removed. The engagement of the first functional part 5 of the securing device 2/5 in the second functional part 2 was removed by the first functional part 5 springing away when the connection between the first plug part 3 and the second plug part 4 was released. The securing device 2/5 has thus reached a release position in which it allows the anchoring connection between the first closure element S1 and the second closure element S2 to be removed if there is no connection between the first plug part 3 and the second plug part 4.

Fig. 2 also shows that the safety device 2/5, in particular its first functional part 5, is designed as a lock which, if there is no connection between the first plug part 3 and the second plug part 4 (after springing away), at least partially closes an insertion opening 4a of the plug part designed as a plug socket 4. The second functional part 2 fixes this closed position of the safety device 2/5 in a form-fitting manner.

i · · · &igr;&iacgr;

by blocking a movement of the first functional part 5 away from the insertion opening 4a with a locking section 2d, which comes into contact with the first functional part 5 of the safety device 2/5. Thus, even in the release position of the safety device 2/5, there is an operative connection between the first functional part 5 and the second functional part 2 of the safety device 2/5.

Only after the second functional part 2 has moved away when an anchoring connection is established between the first closure element S1 and the second closure element S2 can the closure of the insertion opening 4a be released again by pushing back the first functional part 5 of the securing device 2/5 against its spring force. This also protects the system according to the invention against incorrect assembly, since the plug 3 cannot be plugged in as long as there is no anchoring connection between the first closure element S1 and the second closure element S2.

The securing device 2/5 is thus arranged and designed in such a way that, in the absence of an anchoring connection between the first closure element S1 and the second closure element S2, it prevents the establishment of a connection between the first plug part 3 and the second plug part 4 and, in the presence of such an anchoring connection, it allows the establishment of a connection between the plug parts 3, 4.

If an operator now pulls on the handle 6 in the direction of the arrow P1 (Fig. 1, 2) starting from the position shown in Fig. 2, the first flank 6b of the jaw 6a of the handle 6 moves the locking element 2c of the second, rotatably mounted functional part 2, which is adjacent to it, on a circular path (clockwise in the selected illustration). The locking element 2c can be guided in a slot-like guide L in a cover wall of the assembly channel 8.

This movement also causes the end stop section 2a of the second functional part 2 to move in a circular arc until it finally comes into contact with a wall part 8a of the assembly channel 8 (Fig. 3), so that the rotary movement of the second functional part 2 is stopped. In the event that the second functional part 2 -

as described above - is also designed as a closure element, a positive mechanical connection of the functional part 2 with the first closure element S1 is also eliminated.

In principle, the anchoring of the movable component with the stationary component can already be released from the position shown in Fig. 2 by moving (displacing) the movable component in the direction of arrow Q so that the first closure element S1 is disengaged from the opening 8g in the bottom 8f of the assembly channel 8. However, if a higher-level anchoring device VE (cf. Fig. 4) is present, such a release of the anchoring (unhindered displacement of the second closure part S2) can still be blocked by this higher-level anchoring device as long as the handle 6 has not reached the position shown in Fig. 3.

The illustrated embodiment of the system according to the invention shows further advantageous features. For example, it has a self-reversing force support for the anchoring or release process of stationary and movable components and corresponding to the process for establishing or releasing the anchoring connection between the closure elements S1, S2 attached to these components.

By rotating the second functional part 2 of the securing device 2/5 by means of the handle 6, the pinion 9, which is also located in the assembly channel 8, in the region of its wall parts 8d, 8e, is driven to rotate (in the selected illustration, counterclockwise), since the second functional part 2 is designed as a toothed segment 2e on a side opposite the pinion 9 and is in engagement with the pinion 9 there.

The pinion 9 is thereby subject to the effect of a spring which is also mounted in the area of the mounting channel 8 (passing through an opening between the wall parts 8b, 8c), which is advantageously designed as a tension spring 7 and is fastened at one end to the above-mentioned suspension pin 10. The other end of the tension spring 7 is fastened to a fastening point B on the movable component and is pivotably mounted about this fastening point B.

When the state of the system according to the invention shown in Fig. 1 is present, the tension spring 7 and the pinion 9 inhibit a rotational movement of the second functional part 2 in a clockwise direction, so that the operation of the handle 6 in order to enable a release of the anchor connection takes place in the direction of the arrow P1 initially against the force of the tension spring 7.

The suspension pin 10 for the tension spring 7 located on the pinion 9 is initially in a position in front of a reversal point that is lower in the drawing (denoted by a cross U). This is illustrated in Fig. 1, among other things, by the fact that the longitudinal axis F-F of the tension spring 7 is located below a center axis R-R of the pinion 9 that runs parallel to this longitudinal axis F-F and on which the reversal point U lies.

Starting from the state shown in Fig. 1, when the handle 6 is operated, the suspension pin 10 initially moves in the direction of this reversal point U (dead center) (to the right in the drawing). The two axes F-F, R-R of the tension spring 7 and the pinion 9 move closer together until they coincide at the reversal point U. (This intermediate state is not shown in the drawing.)

If the reversal point U is exceeded, as is illustrated in Fig. 2 (and 3) by the fact that the longitudinal axis F-F of the tension spring 7 is located above the parallel central axis R-R of the pinion 9, the tensile force of the tension spring 7 additionally drives the pinion 9 in the direction of the arrow P1. As a result, the entire second functional part 2 with the locking element 2c is rotated via the toothed segment 2e to a position as shown in Fig. 2, which - as already mentioned - already enables the removal of the movable component, although the second functional part 2 has not yet reached its end position.

From the above it has already become clear that the second functional part 2 - in comparison with the first functional part 5 of the safety device 2/5 - is more complex

(end stop section 2a, catch 2b, locking element 2c, blocking section 2d, toothed segment 2e), whereby it can advantageously assume a function as a control disk in addition to its function as a component of the safety device 2/5 and its possible function as a locking part.

There is also an additional function. The second functional part 2 can (in conjunction with the first closure element S1) also prevent the handle 6 from being brought into the closed position when the movable component is reinstalled, as long as the movable component is not in exactly the right position.

In order to make the latter possible, the second functional part 2, which is basically circular-segment-shaped when viewed from above, has a special contour design on a side facing the first closure element S1. The contour of the second functional part 2 has a particularly concave contact section 2f for the head S1a of the first closure element S1, which is effective in the rotational position of the second functional part 2 shown in Fig. 2. In this position, the contact section 2f rests on the first closure element S1 over approximately a quarter of the circumference of the head S1a, which prevents the second functional part 2 from rotating further. The locking element 2c is only partially located within the catch mouth 6a and, under the action of the tension spring 7, has come to rest on a second flank 6c opposite the first flank 6b of the catch mouth 6a.

If - as shown in Fig. 3, which shows the system according to the invention in a second state after the electrical plug connection has been removed - the movable component (including the parts mounted on it, such as the second functional part 2, the mounting channel 8 with the second closure element S2, etc.) is moved away from the first closure element S1 in the direction indicated by the arrow Q in order to remove it, the contact between the second functional part 2 and the first closure element S1 is removed. This allows the second functional part 2 to continue to rotate. This happens under the effect of the tensile force of the spring, which continues to rotate the pinion 9 anti-clockwise, causing the second functional part 2 to move clockwise into an end position.

· I

During this movement, the locking element 2c emerges from the catch mouth 6a of the handle 6. The geometry of the locking element 2c is adapted to that of the catch mouth 6a, in particular to that of the second flank 6c of the catch mouth 6a, in such a way that the handle 6 can no longer be pushed back into a position that enables closing (Fig. 2) because the return path is blocked by a locking section 2g of the locking element 2c that acts to block the second flank 6c of the handle 6.

This safety feature prevents incorrect operation, which could lead to incorrect locking. Only when the contact shown in Fig. 2 between the second functional part 2 and the first locking element S1 is re-established by a movement of the movable component (in the opposite direction to the arrow Q), can the anchoring connection between the first locking element S1 and the second locking element S2 be established and locked by the safety device 2/5 by operating the handle 6 in the opposite direction to the arrow PI, with this connection process then being the reverse of the release process. It is important that the contact section 2f of the second functional part 2 forms an end N, in particular shaped as a tip, nose or cam, with an arcuate peripheral region of the second functional part 2. When the anchoring connection between the locking elements S1, S2 is created (displacement of the movable component in the opposite direction to the arrow Q, approach of the second functional part 2 and the first locking element S1), this end N first comes into contact with the head S1a of the first locking element S1 (Fig. 3). Due to its eccentric arrangement with respect to a central axis X-X through the head S1a, which runs parallel to the direction of displacement Q, the end N causes the second functional part 2 to rotate anti-clockwise when the movable component is further displaced in the opposite direction to the arrow Q and to return to the position shown in Fig. 2, whereby the locking element 2c of the second functional part can again be received by the catch mouth 6a of the handle 6.

The disc-shaped second functional part 2 is designed to be stepped over its thickness (which runs perpendicular to the plane of the drawing in the selected illustration). The end stop section 2a has a first thickness and is arranged in such a way that it

- as already mentioned - can overlap the head S1a of the first closure element S1. In the remaining area which is stepped towards the end stop section 2a (locking section 2d, toothed segment 2e, contact section 2f), the second functional part 2 has a second (in particular greater than the first) thickness and is arranged in such a way that in this thickness range, a lateral contact can be made in some areas on the head SIa of the first closure element S1 and on the first functional part 5 of the safety device 2/5. The locking element 2c of the second functional part 2 has a third, preferably even greater thickness.

As already mentioned, the system according to the invention can advantageously be integrated as a subsystem in an anchoring device VE, as shown in Fig. 4. In the drawing, the first closure element S1 is located on a base 11 attached to the stationary component, the securing device 2/5 with its two main functional parts 2, 5 and the other parts, such as the assembly channel 8, are not shown. The possible position of these parts in the higher-level anchoring device VE is, however, clear from the illustration of the handle 6, which can be connected to these parts according to the illustrations in Figs. 1 to 3.

The illustration in Fig. 4 shows that a stable anchoring between the stationary component and the movable component can preferably be achieved using at least one, preferably two, locking part(s) 13 connected to the handle 6 via a lever system 12a, 12b, 12c. A locking part 13 can - as shown - interact with a part that is designed in the same way as the first closure element S1 (and is therefore identified by the same reference numeral). The handle 6 and individual parts of the lever system 12a, 12b, 12c can - as shown - be connected to one another and to the locking part 13 via joints G1, G2, G3, G4, and the locking part 13 itself can also be attached to the movable component via a joint G5 and can thus be pivoted in different directions for operation. The directions of movement of the joints G1, G2, G3, G4 during an opening movement (arrow P1) of the handle 6 are illustrated by the arrows P2, P3, P4, P5 in Fig. 4. · &kgr; ■

·

Due to the anchoring connection of the locking part 13 to the closure element S1 shown in Fig. 4, in the presence of the higher-level anchoring device VE, a movement of the entire movable component to which the handle 6 is attached in the removal direction (arrow Q) is prevented in both the state of the system according to the invention shown in Fig. 1 and in Fig. 2. This is only possible when the handle is pivoted into the position of the handle shown in Fig. 3, since the locking part 13 then releases the closure element S1. Therefore, the state of the system according to the invention shown in Fig. 3 (not already in Fig. 2) for the described embodiment indicates the end position in particular of the handle 6 and of the second functional part 2 of the safety device 2/5.

From the state of the system according to the invention shown in Fig. 1, pivoting of the handle 6 - as shown in Fig. 4 - spaced by a radius R from a hinge point G2 (arrow direction PI) about this hinge point G2 is not possible because the safety device 2/5 is in the locking position, as explained above.

As is already clear from the above statements, the invention is not limited to the embodiment shown, but also includes all embodiments that have the same effect within the meaning of the invention, in particular a different embodiment of the closure elements S1, S2. For example, the first closure element S1 could also be designed as a ring (as described, for example, in DE 199 33 835 A1) and the second closure element S2 could be designed in a suitable complementary manner.

Likewise, the scope of the invention is not departed from if, instead of the described mechanical safety device 2/5, an electrically triggered and/or electromagnetically actuated safety device is provided, for example by interrupting an electric circuit.

The second functional part 2 of the safety device could - as already indicated - also be advantageously designed and mounted on the movable component in such a way that it can be rotated and/or shifted relative to the first

Closure element S1 can be moved into a closed position in which it forms an at least positive anchoring connection with the first closure element S1, in particular via a closure section formed on it, so that the second functional part of the securing device 2/5 would also act as a closure element - in addition to or as an alternative to the second closure element S2 shown in the exemplary embodiment on the movable component.

In addition, the person skilled in the art can provide additional technical design features of the system according to the invention, e.g. that the handle 6, as shown in Fig. 1, has a closed position which it assumes when the anchoring connection between the closure elements S1, S2 is present (contact with a wall part 8e of the assembly channel 8) and which is visually clearly different from the open position (Fig. 3) of the handle 6 which it assumes when the anchoring connection is not present (protruding from the wall part 8e of the assembly channel 8). A non-locking of the entire system is thereby made visually obvious in an advantageous manner.

With regard to further possible features of a higher-level anchoring device VE, reference is made in full to the German utility model application 200 20 753.9.

Furthermore, the invention is not yet limited to the combination of features defined in claim 1, but can also be defined by any other combination of specific features of all the individual features disclosed overall. This means that in principle practically every individual feature of claim 1 can be omitted or replaced by at least one individual feature disclosed elsewhere in the application. In this respect, claim 1 is to be understood as merely a first attempt at formulating the invention.
