• die Verschiebeeinheit mit einem Federelement ausgebildet ist, mit welchem die Lamellenelemente beim Verschieben aus der Offenposition zwischen den Führungsschienen in die Verschlussposition zwischen den Haltebacken aufgefächert werden.

According to the invention, it is provided according to the first-mentioned solution that

• the holding jaw module is designed with guide rails for guiding a displacement unit between a closing position bridging the holding jaws and an open position bridging the guide rails and permitting the reception of the closing wedge module,
• the displacement unit is formed from at least two strip-shaped lamellar elements, the fan-like overlapping by means of a at one end the lamellar elements arranged pivot axis are pivotally connected to each other, and
• the displacement unit is formed with a spring element, with which the plate elements are fanned out when moving from the open position between the guide rails in the closed position between the holding jaws.

In a vehicle door as a vehicle door, which is coupled by means of the locking wedge system with a side door frame as a structural part of a vehicle body, which now relative to the axis of symmetry of the holding jaw module obliquely extending keyway of the holding jaw is a starting slope for the associated striker, if this holding jaws relative to the vehicle vertical direction of the lower the two holding jaws of the holding jaw module is. With such a run-on slope is achieved that an obliquely down hanging vehicle door is automatically brought into this correct position with this run-in slope.

Of course, it makes sense not only to form a holding jaw with a run-on slope, but also both holding jaws of a holding jaw module with a run-on slope, so that the two run-on slopes are directed conically towards one another. The closing wedges are adapted thereto with obliquely running to each other wedge edges.

With such a displacement unit according to the invention, the starting slope of the holding jaw is compensated. If the vehicle door is closed as a vehicle flap, the closing wedge module is introduced into the holding jaw module for this purpose and at the same time the displacement unit is moved from the closed position in the direction of the vehicle interior between the guide rails into the open position. Since the holding jaws at the Einführstirnseite of the holding jaw module have a greater distance than the vehicle interior facing end side, the displacement unit is pushed together like a fan overlapping. Conversely, the vehicle door is opened, so the Latching module led out of the holding jaw module, the displacement unit is moved from lying between the guide rails open position in the closed position between the holding jaws and fanned out again, so that the holding jaws are bridged.

Preferably, in this embodiment of the invention, the two lamellar elements biasing in Auffächerungsrichtung spring element is formed as arranged on the pivot axis leg spring whose ends are each supported against a lamella element of the displacement unit.

• die Verschiebeeinheit aus wenigstens zwei streifenförmigen Lamellenelementen gebildet ist, die fächerartig überlappend mittels einer an einem Ende der Lamellenelemente angeordneten Spannfeder gegeneinander verschwenkbar verbunden sind, wobei die Lamellenelemente beim Verschieben aus der Offenposition zwischen den Führungsschienen in die Verschlussposition zwischen den Haltebacken aufgefächert werden.

According to the invention, it is provided by the second-mentioned solution that

• the holding jaw module is designed with guide rails for guiding a displacement unit between a locking position bridging the holding jaws and an open position bridging the guide rails and allowing the reception of the closing wedge module, and
• the displacement unit is formed from at least two strip-shaped lamellar elements, which are connected in a fan-like overlapping manner by means of a tension spring arranged at one end of the lamellar elements, wherein the lamellar elements are fanned out from the open position between the guide rails into the closed position between the holding jaws during displacement.

Even with such a displacement unit according to the invention, the starting slope of the holding jaw is compensated and fulfills the same function as the displacement unit described above. The difference from the displacement unit described above is that instead of a leg spring, a tension spring is used, which simultaneously connects the two plate elements. Preferably, the spring element is designed as an omega spring. With such an omega spring, the two lamellar elements are connected simultaneously.

• das Haltebackenmodul mit Führungsschienen zur Führung einer Verschiebeeinheit zwischen einer die Haltebacken überbrückenden Verschlussposition und einer die Führungsschienen überbrückenden und die Aufnahme des Schließkeilmodul zulassenden Offenposition ausgebildet ist, und
• die Verschiebeeinheit aus wenigstens zwei streifenförmigen Lamellenelementen gebildet ist, die mittels eines elastischen Mittelelementes derart verbunden sind, dass unter Nutzung der elastischen Eigenschaft des Mittelelementes die Lamellenelemente aus der Offenposition auffächerbar oder aus der Verschlussposition wieder zusammenlegbar sind.

According to the invention, it is provided by the third-mentioned solution that

• the holding jaw module is designed with guide rails for guiding a displacement unit between a locking position bridging the holding jaws and an open position bridging the guide rails and allowing the reception of the closing wedge module, and
• the displacement unit is formed from at least two strip-shaped lamellar elements, which are connected by means of an elastic middle element such that the lamellar elements can be fanned out of the open position or be folded out of the closed position again using the elastic property of the middle element.

Even with such a displacement unit according to the invention, the starting slope of the holding jaw is compensated and fulfills the same function as the displacement unit described above. The difference from the above-described displacement unit lies in the fact that the two lamellar elements are connected by means of an elastic central element which, in the closed position, presses apart the two lamellar elements, so that these rest against the holding jaws. By moving into the open position, the two lamellar elements are compressed due to the elasticity of the central element. Thus, a one-piece displacement unit can be created with an elastic central element.

Moreover, it is particularly advantageous if, in accordance with further development, a spring element is arranged in the region of the guide rails, with which the displacement unit is biased in the direction of the closure position. With such a spring element ensures that the displacement unit remains in its closed position. The displacement unit is moved against the spring force of this spring element in its open position.

Finally, a last advantageous development of the invention provides that the lamellar elements cover with an end face of the holding jaw module Flanges are formed with adapted to the wedge shape of the keyways lugs. This ensures that the Einführstirnseite the holding jaw module is covered with the vehicle door open and gives an optimal design impression.

This in FIG. 1 illustrated and known closing wedge system 1 represents a coupling device, with which - as described above - by means of a striker module 2 and a holding jaw module 3, a vehicle door 11 is coupled to a side wall frame 12 of a vehicle body 10. In addition to such a coupling device is usually in addition a conventional vehicle lock (in FIG. 1 not shown), this coupling device leads to a stiffening of the vehicle body 10.

The Figures 2 and 3 show a lock wedge module 2 and a holding jaw module 3 of a locking wedge system 1 according to the invention. To FIG. 2 are in a closing wedge holder 2.3 of the striker module 2 on opposite sides in the vertical direction R (z-direction) to a symmetry axis S each have a closing wedge 2.1 and 2.2 slidably disposed. These two closing wedges 2.1 and 2.2 have corresponding wedge surfaces to form a wedge edge 2.10 and 2.20.

To FIG. 3 comprises the holding jaw module 3 two spaced apart on a base plate 3.5 holding jaws 3.1 and 3.2, each with a keyway 3.11 and 3.21. For coupling the striker module 2 with the holding jaw module 3, the striker module 2 is introduced via an insertion end 3.3 of the holding jaw module 3 in the insertion direction E, so that the striker module 2 is located between the two holding jaws 3.1 and 3.2.

By means of a drive device, not shown, the two locking wedges 2.1 and 2.2 are extended in opposite directions R (z-direction) from a non-coupling position in a coupling position, whereby the two locking wedges 2.1 and 2.2 with their end-side wedge surfaces in each of the adapted to the contour of these wedge surfaces keyways 3.11 and 3.21 are pressed and thus a non-positive and positive connection between the locking wedge module 2 and the holding jaw module 3 is produced.

However, the wedges 2.1 and 2.2 of the striker module 2 are not aligned parallel to each other, more precisely, the wedge edges 2.10 and 2.20 of these strikers 2.1 and 2.2 are not parallel to the axis of symmetry S of the striker module 2, but extend in the insertion direction E obliquely toward each other. Thus, the wedge edge 2.10 of the closing wedge 2.1 and the wedge edge 2.20 of the closing wedge 2.2 each have an inclination angle α with the axis of symmetry S. This means that the end-side distance a of the two wedge edges 2.10 and 2.20 at the insertion-side end 2.4 of the striker module 2 is smaller than that Distance A at the opposite end 2.5. In adaptation to this obliquely with respect to the axis of symmetry S extending locking wedges 2.1 and 2.2 are also the splines 3.11 and 3.21 of the two holding jaws 3.1 and 3.2 running obliquely to the axis of symmetry S of the striker module 3 running. This means that the holding jaw surface 3.12 receiving the keyway 3.12 has an inclination angle α relative to the symmetry axis S and the holding jaw surface 3.22 receiving the keyway 3.21 also has an inclination angle α with respect to the symmetry axis S, wherein the distance B of these two holding jaw surfaces 3.12 and 3.22 at the insertion end side 3.3 is greater than the distance b at the opposite end of the two holding jaws 3.1 and 3.2. Thus fit in the introduction of the locking wedge module 2 in the holding jaw module 3, the respective conical curves of the two closing wedges 2.1 and 2.2 and the two holding jaws 3.1 and 3.2 together.

Of course, it is also possible, based on the vehicle vertical direction (z-direction) only the lower striker 2.2 of the striker module 2 with an opposite to the axis of symmetry S oblique wedge edge form 2.20. The wedge edge 2.10 of the upper closing wedge 2. 1 then runs according to the prior art parallel to the axis of symmetry S. Adapted to this are the holding jaws 3.1 and 3.2 of the holding jaw module 3, based on the vehicle vertical direction (z-direction) only the lower holding jaws 3.2 relative to the Symmetry axis S has a slanted keyway 3.21 or holding jaw surface 3.22.

At the opposite ends of the Einführstirnseite 3.3 of the two jaws 3.1 and 3.2 each include a guide rail 3.10 and 3.20 for receiving a in FIG. 3 not shown, which serves with open vehicle door 11, so if the lock wedge module 2 is not retracted into the holding jaw module 3, the space between the two holding jaws 3.1 and 3.2 as well as in the insertion end face 3.3 form-fitting cover. For this purpose, such a displacement unit 4 between a closure position between the two holding jaws 3.1 and 3.2 and a space between the two holding jaws 3.1 and 3.2 releasing open position between the guide rails 3.10 and 3.20 displaceable. Therefore, the holding jaw surfaces 3.12 and 3.22 of the holding jaws 3.1 and 3.2 together with the adjoining end faces of the two guide rails 3.10 and 3.20 form a uniform surface.

The two guide rails 3.10 and 3.20 are frontally and frontally covered by an angle-shaped cover plate 3.6, wherein on the front side of a spring element 3.4 is arranged, the function will be explained below.

A displacement unit 4 in different embodiments will be described below with reference to FIGS. 4 to 14 described.

The displacement unit 4 according to the FIGS. 4 and 5 consists of a first strip-shaped thin plate element 4.1, a second strip-shaped thin plate element 4.2 and a leg spring as a spring element 4.3. Each of the lamellar elements 4.1 and 4.2 is L-shaped with a strip-shaped element 4.10 or 4.20 as a long leg of the L-shape and one of the strip-shaped element 4.10 or 4.20 at right angles projecting flange 4.11 or 4.21 designed as a short leg of the L-shape ,

At the opposite end to the flange 4.11 4.10 of the strip-shaped element is followed by a circular connecting flange 4.13 with a short pivot axis 4.14, via which the two plate elements 4.1 and 4.2 are pivotally connected to each other. For this purpose, the second plate element 4.2 opposite to the flange 4.21 as well as a connecting flange 4.24 with an adapted to the diameter of the pivot axis 4.14 axis opening 4.24.

The first lamellar element 4.1 also has an outgoing from the connecting flange 4.13 and widening cone-shaped overlap region 4.12, which is delimited by means of a running into the flange 4.11 shoulder 4.120 with a thickness of the second fin element 4.2 corresponding shoulder height. In connected via the pivot axis 4.14 state of the two blade elements 4.1 and 4.2, this overlap area is 4.12 fan-like overlapped by the second blade element 4.2. If this overlapping area 4.12 is completely overlapped by the second lamella element 4.2, its side edge rests directly against the shoulder 4.120 and defines the open position of the displacement unit 4 in which it follows FIG. 9 located between the guide rails 3.10 and 3.20. In this state is according to FIG. 8 the free edge of the overlap region 4.12 at a running on the back of the second fin element 4.2 4.220 shoulder, which also has an overlap 4.22 of the second fin element 4.2 according to FIG. 5 Are defined.

In the connected state of the two blade elements 4.1 and 4.2, the leg spring is arranged as a spring element 4.3 on the pivot axis 4.14, wherein the ends are each fixed in a holding 4.16 of the first fin element 4.1 and in a holding 4.26 of the second fin element 4.2 such that the two fin elements 4.1 and 4.2 are pivoted against each other, so are biased in Auffächerungsrichtung D1 and D2.

If the displacement unit 4 is in its open position between the two guide rails 3.10 and 3.20, the closing wedge module 2 is clamped between the two holding jaws 3.1 and 3.2. With the opening of the vehicle door, the striker module 2 is extended from the holding jaw module 3, whereby the displacement unit 4 pushed from its open position between the guide rails 3.10 and 3.20 by a prestressed spring element 3.4 forward in the direction of Einführstirnseite 3.3 becomes. Here, the closing unit 4 is fanned out due to the spring bias of the spring element 4.3, ie the two lamellar elements 4.1 and 4.2 are fanned out in their Auffächerungsrichtung D1 or D2 until the outer edges positively abut positively against the holding jaw surfaces 3.12 and 3.22 of the two holding jaws 3.1 and 3.2 , wherein also on the flanges 4.11 and 4.21 together with their lugs 4.15 and 4.25 a positive connection of the holding jaws 3.1 and 3.2 is achieved at the Einführstirnseite 3.3 of the holding jaw module 3, as in FIG. 7 is shown. This represents the closing position of the displacement unit 4, in which the overlapping area 4.12 in the front view according to FIG. 7 is only partially overlapped by the second fin element 4.2 or the overlapping 4.22 of the second fin element 4.2 in the rear view according to FIG. 6 is only partially overlapped by the first fin elements 4.1. By means of the spring element 3.4, the displacement unit 4 is held in its closed position.

To close the vehicle door, the striker module 2 is inserted via the insertion end 3.3 of the holding jaw module 3 between the holding jaws 3.1 and 3.2 while the displacement unit 4 against the spring force of the spring element 3.4 in the area of the guide rails 3.10 and 3.20 moved until this is in accordance with their open position FIG. 9 reached. With the displacement of the displacement unit 4 from its closed position according to FIG. 7 according to their open position FIG. 9 the two plate elements 4.1 and 4.2 are compressed due to the oblique holding jaw surfaces 3.12 and 3.22 of the two holding jaws 3.1 and 3.2 until the overlap areas 4.12 and 4.23 are completely overlapped and therefore in the front view according to FIG. 9 only the shoulder 4.120 is visible.

If the holding jaw module 3 is executed only with a single obliquely extending keyway 3.21 of the lower holding jaw 3.1, the displacement unit has 4 according to the FIGS. 4 and 5 of course, the same structure.

The FIG. 10 shows an alternative embodiment of the displacement unit 4. This displacement unit 4 according to FIG. 10 differs from the one according to the FIGS. 4 and 5 in that, instead of a leg spring as the spring element 4.3, an omega spring is provided. Otherwise, the structure of this displacement unit 4 corresponds to FIG. 10 the one according to the FIGS. 4 and 5 ,

This displacement unit 4 also comprises a first plate element 4.1 and a second plate element 4.2. The omega spring as the spring element 4.3 connects the two plate elements 4.1 and 4.2, characterized in that one leg of the omega spring frictionally with the first fin element 4.1 and the other leg of the omega spring are positively connected to the second fin element 4.2. Also in this displacement unit 4, the two blade elements 4.1 and 4.2 are biased by means of this omega spring in Auffächerungsrichtung, so that these blade elements 4.1 and 4.2 both in the open position according to FIG. 9 as well as in the closed position according to FIG. 3 pressed against the guide rails 3.10 and 3.20 or to the holding jaws 3.1 and 3.2.

With the use of an omega spring as a spring element 3.4, the first plate element 4.1 and the second plate element 4.2 each have no connecting flange 4.13 or 4.23 with associated pivot axis 4.14 or 4.24 axis opening and no holding 4.16 or 4.26.

The FIGS. 11 and 12 show a further alternative embodiment of a displacement unit 4, wherein instead of the omega spring of the displacement unit 4 after FIG. 10 an arcuate tension spring is used as the spring element 4.3. This spring element 4.3 connects the two fin elements 4.1 and 4.2 in the region of the flanges 4.11 and 4.21, wherein the convex Side of the tension spring in the direction of the flanges 4.11 and 4.21 shows. Also in this displacement unit 4, the connection of the two plate elements 4.1 and 4.2 is carried out to produce a direction of the fanning direction in D1 and D2 directed spring preload. The two blade elements 4.1 and 4.2 according to their structure that of the displacement unit 4 according to FIG. 10 , The FIG. 11 shows the displacement unit 4 in its open position as shown FIG. 9 and the representation after FIG. 12 corresponds to the closing position according to FIG. 4 ,

The FIGS. 13 and 14 show a last alternative embodiment of a displacement unit 4, which also includes a first fin elements 4.1 and a second fin elements 4.2, but which are cuboid with a thickness of the locking wedges 3.1 and 3.2 and the thickness of the guide rails 3.10 and 3.20 example. Made of a plastic material.

The two lamellar elements 4.1 and 4.2 are connected by means of an elastic middle element 4.4 made of a plastic material form-locking and surface-locking in such a way that in the closed position of the sliding element 4 according to FIG. 13 due to the elastic property of the middle element 4.4, the two plate elements 4.1 and 4.2 pressed apart and pressed against the holding jaws 3.1 and 3.2 of the holding jaw module 3. If this displacement unit 4 is pushed out of this closure position into the open position between the guide rails 3.10 and 3.20, the two lamellar elements 4.1 and 4.2 due to the obliquely extending holding jaw surfaces 3.12 and 3.22 using the elastic property of the central element 4.4 in the closed position according to FIG. 14 pressed together.
