Description

FIELD OF THE INVENTION

The invention relates to a bridge of durchschreitbaren in a passage direction transition between two by means of a coupling device hingedly interconnected vehicle parts, comprising at least one person entdeckbares plate pair consisting of a respective base plate with a base plate surface and a slidably resting bridge plate thereon with a bridge plate surface, wherein the base plate and the bridge plate overlap each other in the passage direction, wherein further both the base plate and the bridge plate are pivotally mounted on a respective frame around a respective transverse axis to the pivot axis, and being arranged in the passage direction, the pivot axis of the base plate at one of the bridge plate facing away from the base plate is and the pivot axis of the bridge plate is disposed on one of the base plate averted end of the bridge plate.

STATE OF THE ART

In general passenger and freight traffic vehicles, especially rail vehicles (but also articulated buses) are used, which consist of several parts of the vehicle, which are hinged together. In order to allow passengers a safe transition between two such vehicle parts, transitions are used. These transitions include a bridge, which bridges a distance of the two vehicle parts to each other, which is constructive and depends, for example, on the type of coupling mechanism of the vehicle parts and the maximum pivoting angle of the vehicle parts during cornering of the vehicle.

A possible embodiment of such a bridge is constructed of a plurality of tread members link bridge, as for example from the AT 10938 U1 is known. However, such a link bridge is relatively expensive and therefore expensive, which is why usually a simpler solution with bridge plates is used. For this purpose, it is known from the prior art to use plate pairs consisting of a respective base plate and a bridge plate, wherein the bridge plate rests on the base plate and slides. The base plate in turn is supported by a support device and can be designed to be resilient in a vertical direction, wherein the spring travel in practice is relatively small.

A disadvantage of this solution is that the bridge has strong unevenness in an occurring height offset of the two vehicle parts that alternately significantly exceed an imaginary ideal line and fall below. The result is a very uneven bridge with stumbling edges and barriers.

OBJECT OF THE INVENTION

Object of the present invention is therefore to find a bridge plate solution that allows, regardless of the position of the articulated vehicle parts to each other, especially with a strong height offset between the vehicle parts, a bridge as close to the ideal line, without stumbling edges and barriers.

PRESENTATION OF THE INVENTION

The core of the present invention is first of all the realization that a bridge course close to the ideal line, without tripping edges and barriers, is realized precisely when base and bridge plates are always in contact, ie. H. essentially independent of the position of the vehicle parts connected to one another in an articulated manner, are aligned as parallel as possible. This means that the normal distance from any point on a baseplate surface to any point on a bridgeplate surface will essentially always remain the same. The normal distance is the distance that is normally measured on the base plate surface. It is understood that this applies to the normal operating condition of the vehicle, in which a certain maximum height offset and certain maximum swivel angle between the vehicle parts are not exceeded and the bridge or base plates are not in a maintenance position. In this case, the base and bridge plates represent those parts of the transition, which are trodden by persons passing through the transition between two vehicle parts, for example a rail vehicle or a jointed bus.

In practice, satisfactory results are achieved if the normal distance can vary slightly by a mean characteristic of the respective pair of points, with no more than 5% of the mean being allowed as a variation. As a result, a slightly curved base plate is taken into account, d. H. it is also permissible if the base plate is not perfectly flat, although typically a flat base plate will be used.

The bridge plate, on the other hand, is typically curved in an end region towards the base plate and lies correspondingly with this end region on the base plate or slides on the base plate. In this case, the bridge plate is held by gravity on the base plate, ie in a against the Seen gravity-facing vertical direction, the bridge plate is arranged after the base plate.

Especially when there is a height offset in the vertical direction between the vehicle parts, both bridge plates and base plates must be pivotable in the vertical direction in order to compensate for the height offset by a course of bridge plate surface and base plate surface following approximately an ideal line. For this purpose, bridge plates and base plates are pivotably mounted on different frames, wherein the respective pivot axis is transverse to the passage direction. In order to guarantee a continuous transition, bridge plates and base plates in the passage direction overlap one another, wherein the bridge plates are slidably mounted on the base plates. Accordingly, the pivot axes are arranged at those ends of the base and bridge plates, which point away in the passage direction from the overlap region.

To a normal distance measured on the base plate surface, between an arbitrarily selected point on the base plate surface and an arbitrarily selected point on the bridge plate surface except for a mutually dependent on the position of the interconnected vehicle parts deviation of 5% to a characteristic of the specific pair of points average hold, the base plates are each slidably mounted on a carrier, which limits the pivotability of the base plate in dependence on the position of the interconnected vehicle parts to each other. For this purpose, the respective carrier is designed as a rigid or rigid element and hingedly connected to the two frames.

Therefore, in a bridge, a transitional passageway between two vehicle parts hingedly connected together by a coupling device, comprising at least one pair of personable plates each consisting of a base plate having a base plate surface and a bridge plate slidably supported thereon with a bridge plate surface, the base plate and the bridge plate overlap each other in the passage direction, wherein further both the base plate and the bridge plate are pivotally mounted on a respective frame about a pivot axis transverse to the passage direction, and seen in the passage direction, the pivot axis of the base plate at one end of the base plate facing away from the base plate is arranged and the pivot axis of the bridge plate is disposed on one of the base plate averted end of the bridge plate, according to the invention provided that the di e base plate on a movable support which is pivotally connected to both frames, slidably rests to limit the pivotability of the base plate in dependence on the position of the interconnected vehicle parts to each other.

The frame, to which the at least one bridge plate is attached, is normally a middle frame, which is arranged between the vehicle parts. The middle frame is usually supported on a coupling device, by means of which the vehicle parts are coupled or articulated with each other.

In this case, the base plate is fixed to an end frame mounted in the end portion of a vehicle part. However, it is of course conceivable that the base plate on the center frame and the bridge plate are pivotally mounted on the end frame.

In addition, cases are possible where midframe is completely abandoned. Accordingly, then the at least one base plate is mounted on the end frame of a vehicle part and the bridge plate on the end frame of the other vehicle part.

The carrier connects the frame used in each case articulated. Alternatively, if the use of frames is omitted, the wearer can also connect vehicle parts directly to each other, or a vehicle part with a frame. Accordingly, it is provided in a preferred embodiment of the bridge according to the invention that the movable support with an end frame and an end frame or with an end frame and a center frame or with a vehicle part and a vehicle part or with a vehicle part and a center frame or with a vehicle part and an end frame articulated is connected.

Preferably, the mounting of the plates to the frame by means of a hinge belt, which defines the respective pivot axis. In this case, the pivot axis is parallel to a transverse direction, which extends transversely to the passage direction. Since the center frame is not fixed to an end portion of a vehicle part, this transverse direction does not necessarily have to be normal to a longitudinal axis of the vehicle part or to the passage direction. It is therefore provided in a preferred embodiment of the bridge according to the invention, that it is in the frame to which the at least one bridge plate, preferably by means of a hinge belt is pivotally mounted about its pivot axis about a central frame, which is arranged between the two vehicle parts, or around an end frame, which is arranged in the end region of a vehicle part acts.

Accordingly, it is provided in a preferred embodiment of the bridge according to the invention, that it is in the frame to which the at least one base plate, preferably by means of a hinge belt is pivotally mounted about its pivot axis about an end frame, which is arranged in the end region of a vehicle part, or about a middle frame, which is arranged between the two vehicle parts is.

In a conventional arrangement, the at least one base plate is fixed by means of the hinge strap to an end frame, which in turn is arranged or fixed in the end region of a vehicle part. In each case, such an end frame is fixed to the end regions of both vehicle parts. Between these are usually two interconnected central frame to which the bridge plates corresponding to the base plates are attached. The bridge according to the invention thus typically consists overall of a combination of two mirror-symmetrically arranged systems, each comprising an end frame with base plate pivoted thereto and a center frame with bridge plate pivotally attached thereto, the systems being interconnected via the center frames.

Typically, the end frame has a traverse on which or in the region of the hinge is attached. This runs in a transverse direction transversely to the passage direction or normal to the longitudinal axis of the vehicle part, whereby the hinge band and thus also the pivot axis of the at least one base plate extend parallel to this transverse direction.

The middle frame usually also has a traverse, on which or in the region of a hinge is attached. This is transverse to the passage direction, but, as already noted, not necessarily normal to the vehicle longitudinal axis, since the center frame during operation is usually not constantly oriented parallel to the vehicle parts or to the or the end frame.

In order to allow a smooth sliding of the base plate on the support, the carrier comprises a sliding plate on which slides the base plate. As a result, the base plate is positioned so that it follows approximately the course of the ideal line. Accordingly, it is provided in a particularly preferred embodiment of the bridge according to the invention that the carrier comprises a sliding plate on which the at least one base plate slidably rests.

The at least one base plate is held by gravity on the respective slide plate. Ie. the at least one base plate is arranged above the respective slide plate and folds due to their pivoting against the vertical direction always on the slide plate and is applied to this.

The sliding plates are flat plates without curvature or curvature, d. H. with curvature zero, carried out so that there is always a surface contact between the at least one base plate and the respective sliding plate when the base plate is also designed as a flat plate substantially flat or without curvature. Accordingly, it is provided in a particularly preferred embodiment of the bridge according to the invention that the at least one base plate is flat, and that regardless of the position of the interconnected vehicle parts to each other, the respective sliding plate and the at least one base plate are parallel to each other.

In order to align the at least one base plate by means of the respective carrier or the respective slide plate approximately following the ideal line, the respective carrier or the respective slide plate is positioned according to an imaginary connecting line between the end frame and middle frame. The carrier has a first and a second end. The first end is connected to the end frame, the second end to the middle frame. These compounds are, as already mentioned articulated, so not rigid to account for changes in position of the vehicle parts to each other.

For this purpose, the first end is connected to a carriage, which is linear on the end frame, transversely displaceable to the passage direction. Therefore, it is provided in a particularly preferred embodiment of the bridge according to the invention that the carrier has a first and second end, and that the first end of the carrier with the end frame via a carriage in a transverse direction, which transverse to the passage direction, preferably normal to a longitudinal axis a vehicle part is connected linearly displaceable.

Preferably, a linear guide is arranged on the traverse of the end frame, on which the carriage is parallel to the transverse direction feasible. Accordingly, it is provided in a particularly preferred embodiment of the bridge according to the invention that the carriage can be guided parallel to the transverse direction in a linear guide arranged on the end frame.

This not only contributes to a lateral offset, ie an offset parallel to the transverse direction, the vehicle parts invoice, but above all a changing distance between end frame and center frame. Not least due to the pivoting of the vehicle parts to each other, the distance between the end frame and the center frame along the longitudinal axis is not the same everywhere. Overall, it follows that a varying distance between the end frame and the center frame along the longitudinal axis must be taken into account. Theoretically, it would be conceivable to address this problem with a carrier consisting of several parts which can telescope in and out of one another. However, the solution according to the invention with said linear guide proves to be much more stable or more mechanically resilient. For this purpose, however, it is necessary to combine the linear guide with a rotation of the carrier against the longitudinal axis. Therefore, the carrier is rotatably mounted on the carriage, wherein the axis of rotation encloses a right angle with the transverse direction, to which the linear guide extends in parallel.

In order to take into account a height offset, the carrier must also be pivotable parallel to the vertical direction, which is why the carriage, preferably on the linear guide, is rotatable. The linear guide represents an axis of rotation which is parallel to the transverse direction, preferably parallel to the pivot axis of the at least one base plate. Accordingly, it is provided in a particularly preferred embodiment of the bridge according to the invention that the carriage is rotatably mounted about an axis of rotation which is parallel to the transverse direction.

Moreover, it is provided in a particularly preferred embodiment of the bridge according to the invention that the carrier is rotatably mounted on the carriage, wherein the axis of rotation encloses a right angle with the axis of rotation of the carriage.

With its second end, the carrier is connected to the center frame or, if no middle frame is present, to another end frame via a spherical bearing. In this case, the second end is preferably designed as a joint head. In conjunction with the attachment of the first end of the carrier to the end frame as described above, this guarantees alignment of the carrier or slide plate along the ideal line. The base plate follows the carrier or the slide plate substantially parallel. Accordingly, the base plate surface and the bridge plate surface are approximately the imaginary ideal line and do not form any strong bumps or barriers. Accordingly, it is provided in a particularly preferred embodiment of the bridge according to the invention that the carrier is mounted with its second end on at least one central frame or end frame spherical, wherein the second end of the carrier is preferably designed as a hinge head.

In addition to the already described possibilities of changing the position of the vehicle parts to each other, also a shaking can occur. Here, the vehicle parts rotate each other by angles of a few degrees, typically by 2 ° to 5 °, wherein the axis of rotation extends through the longitudinal axis of a vehicle part. As a result, a corresponding rotation occurs between the end frame and the middle frame or between the end frame and the end frame. Now, if the bridge plate is made in one piece, it can along the direction that is defined by the pivot axis of the bridge plate, come to a significant increase in the bridge plate of the base plate. To avoid this, the bridge plate is divided along this direction into several parts which are mounted pivotably independently of each other in the hinge, whereby a possible continuous contact of the bridge plate is achieved on the base plate. Accordingly, it is provided in a particularly preferred embodiment of the bridge according to the invention that the at least one bridge plate is divided in the direction of its pivot axis into a plurality, preferably three parts. As a result, a stepless contact of the at least one bridge plate on the at least one base plate is made possible with a rotation of the at least one middle frame relative to a vehicle part about its longitudinal axis.

By the at least one bridge plate slides on the associated base plate, a bridge is formed, which takes into account a changing distance between the vehicle parts or between the middle frame or end frame and end frame. In addition to the situations described, which require a change in this distance, it may, in particular when coupling the vehicle parts come to a reduction in distance to a minimum distance. The maximum possible distance results from the design, for example, from the dimensions of the carrier or the dimensions of the base and bridge plates, in particular along the longitudinal axis. Accordingly, it is provided in a particularly preferred embodiment of the bridge according to the invention that in a parallel arrangement of the center frame and end frame or end frame and end frame whose measured along the longitudinal axis distance to each other in normal operation between 290 mm and 550 mm, preferably between 340 mm and 500 mm is variable , These are typical distances, as they occur in normal operation, where there is no damage to the individual elements occur.

For an accident situation it is envisaged that the mentioned distance between end frames and can again reduce center frame or end frame and end frame. In this case, the at least one bridge plate can slide over the hinge band of the associated base plate and penetrate into a region of the vehicle part provided for this purpose, where it can possibly also bend. The transition remains usable here. Therefore, it is provided in a particularly preferred embodiment of the bridge according to the invention that with parallel arrangement of the center frame and end frame or end frame and end frame their measured along the longitudinal axis distance to each other in an accident situation up to 220 mm, preferably reduced to 170 mm, the at least one bridge plate is preferably feasible in a designated area in a vehicle part.

WAYS FOR CARRYING OUT THE INVENTION

1 shows a schematic representation of a transition 8th between each other by means of a coupling device 39 articulated vehicle parts 2 . 3 , which each have a vehicle longitudinal axis 13 exhibit. The transition 8th includes a bridge 1 that of at least one person in a direction of passage 9 is treadable. The transition 8th becomes transverse to the passage direction 9 from a wave bellows 30 completed, resulting in changes in position of the vehicle parts 2 . 3 can easily deform each other in a suitable manner. In the direction of passage 9 the transition extends 8th from a final frame 10 , which in the end region of the first vehicle part 2 is mounted over two center frames 25 up to another end frame 10 , which in the end region of the second vehicle part 3 is mounted.

2 shows in side sectional view a known from the prior art bridge 1 , This bridge 1 is composed of base plates 4 which are on a middle frame 25 are arranged and from a rigid with the middle frame 25 associated support devices 31 supported as well as bridge plates 6 , The base plates 4 are on the middle frame 25 rotatably and resiliently mounted and thus can in a pointing from bottom to top vertical direction 18 from the support device 31 lift off easily. The bridge plates 6 are each on an end frame 10 pivoted so that the bridge plates 6 parallel to the vertical direction 18 can be pivoted. The end frame 10 are in each case a vehicle part 2 . 3 fixed.

The bridge plates 6 lie on the associated base plates 4 sliding up. Im in 2 shown case, the longitudinal axes 13 the vehicle parts 2 . 3 Although parallel, but there is a vertical offset (in vertical direction 18 ) between the vehicle parts and thus between the two end frames 10 and the center frame 25 , Although allows the arrangement shown bridge plates 6 and base plates 4 a closed walk-in bridge 1 , but this has strong bumps, which represent stumbling edges or barriers, and alternately runs well above or below a likewise drawn ideal line 29 caused by the storage of plates - in this case bridge plates 6 - to the end frame 10 runs.

In contrast, shows 3 an axonometric overview of a transition 8th with a bridge according to the invention 1 , which practically without bumps or barriers closely one (in 3 not shown) ideal line 29 follows.

4 shows an enlarged axonometric view of this transition 8th , The bridge according to the invention 1 includes base plates 4 which is a base plate surface 5 have, and bridge plates 6 which is a bridge plate surface 7 exhibit. The bridge plates 6 lie on the base plates 4 on. In the example shown is in each case a base plate 4 on each end frame 10 pivotally mounted, which in turn on a vehicle part 2 . 3 (not shown here) is fixed. In between there are two middle frames 25 that are interconnected. On each of these is a bridge plate 6 pivoted and is by gravity or by means of a (not shown) spring on the associated base plate 4 held.

5 shows the same view, but without showing the bellows 30 and the bridge plates 6 , As a result, are carriers 15 recognizable, each one a middle frame 25 and an end frame 10 connect with each other. Every carrier 15 includes a sliding plate 14 whose plane is parallel to the carrier 15 and thus essentially, ie, to a maximum deviation of 5 °, parallel to the ideal line 29 (in 5 not shown; see. 1 . 8th . 10 ), the ideal line 29 between the bearings of the base plates 4 at the end frame 10 runs straight. On each slide plate 14 in turn lies one base plate each 4 flat on, with the base plate 4 from gravity on the respective sliding plate 14 is held. Thus runs also base plate 4 almost parallel to the ideal line 29 or deviates from this by no more than 5 °.

Every carrier 15 has a first end 20 and a second end 21 on, the connecting line a carrier longitudinal direction 22 Are defined. With the first end 20 is the carrier 15 at the end frame 10 tethered. This shows 6 an axonometric detail view.

In particular to changes in distance between the respective end frame 10 and middle frame 25 Being able to compensate is the connection of the carrier 15 at the end frame 10 not rigid. Instead, that's the first end 20 with a sledge 16 rotatably connected. The sled 16 sits on a linear guide 19 which are at a cross-direction 12 extending crossbar 32 of the end frame 10 is attached. The sled 16 is through the linear guide 19 parallel to the transverse direction 12 linearly guided. The rotation axis 17 of the carrier 15 on the slide closes with the transverse direction 12 a right angle. A change in distance between the end frame 10 and the center frame 25 is therefore by moving the carriage 16 along the linear guide 19 and simultaneous rotation of the carrier 15 around the axis of rotation 17 compensated.

Besides, the sled is 16 on the linear guide 19 rotatably mounted, wherein the linear guide 19 a rotation axis 34 defined parallel to the transverse direction 12 runs. This results in a height offset between end frame 10 and middle frame 25 the carrier 15 and thus the sliding plate 14 around the axis of rotation 34 tilted.

In the 6 not shown) base plate 4 is by means of a hinged band 27 , which is also parallel to the transverse direction 12 running on the crossbar 32 is mounted, pivoting on the end frame 10 stored. It is through the hinge 27 a pivot axis 11 defined parallel to the transverse direction 12 runs. Thus, the base plate 4 on the slide plate 14 rests, the rotational movement of the carriage 16 or the carrier 15 and thus the sliding plate 14 around the axis of rotation 34 Follow by the base plate 4 around the pivot axis 11 swings. The base plate 4 thus always remains parallel to the carrier 15 or to slide plate 14 aligned.

7 shows an axonometric detail view, in which the connection of the second end 21 of the carrier 15 with a center frame 25 is clearly recognizable. The second end 21 is with a traverse 32 of the middle frame 25 about a spherical bearing 35 connected, the second end 21 this a joint head 33 includes. The spherical bearing 35 thus acts as a fulcrum for the wearer 15 with linear displacements of the carriage 16 along the linear guide 19 or at corresponding rotations of the carrier 15 around the axis of rotation 17 on the carriage and during rotations of the carriage 16 and with it the wearer 15 around the axis of rotation 34 ,

In 7 each is a hinged band 27 recognizable, which likewise at the Traverse 32 of the middle frame 25 is mounted and a pivot axis 26 for the respective bridge plate 6 (in 7 not shown), wherein the pivot axis 26 transverse to the passage direction 9 runs. Thus, also the respective bridge plate 6 the pivoting movement of the associated base plate 4 consequences. Ie. also the bridge plate 4 runs approximately parallel to the ideal line 29 , resulting in a total of a course of the bridge 1 close to the ideal line 29 results.

8th shows a side sectional view of a bridge according to the invention 1 without height offset between the end frames 10 and the center frame 25 , The ideal line 29 runs correspondingly horizontal, normal to the vertical direction 18 ,

9 shows an enlarged view of the dashed rimmed area A from this 8th , This is in particular the arrangement of the bridge plate 6 and base plate 4 recognizable to each other. Here is the base plate 4 as a flat plate without curvature, ie with zero curvature executed. The bridge plate 6 is in its end area, by the bearing of the bridge plate 6 by hinge strap 27 on the middle frame 25 points away, against the vertical direction 18 , to the base plate 4 curved down. The bridge plate 6 is therefore not flat on the base plate 4 on, but only with the said end portion, for this purpose on the base plate 4 facing side a sliding coating 36 having.

The storage of the base plate 4 by hinge strap 27 at the end frame 10 allows a continuous surface resting on the sliding plate 14 which in turn align the base plate 4 parallel to the ideal line 29 (see. 1 . 8th . 10 ) guaranteed. The storage of the bridge plate 6 by hinge strap 27 on the middle frame 25 thus also allows the orientation of the bridge plate 6 on the ideal line 29 , Here, the distance between base plate remains 4 and bridge plate 6 always the same. Specifically, a normal hangs on the baseplate surface 5 measured normal distance 38 between any point 23 on the baseplate surface 5 and any point 24 on the bridge plate surface 7 practically not from the position of the end frame 10 to the middle frame 25 from. The normal distance 38 of the selected pair of points varies by at most 5% around a mean value, this variation on the one hand manufacturing tolerances, on the other hand a possible curvature of the base plate 4 owed.

10 shows the situation with height offset analogous to 8th , It is easy to see that the carriers with the sliding plates 14 parallel to the ideal line 29 are aligned and the base plates 4 flat on the respective sliding plates 14 rest. The bridge plate surfaces 7 For the most part, they are also parallel to the ideal line 29 ; due to the curvature of the bridge plates 6 in the end areas with the sliding coating 36 This results in only a small step in the entire course of the bridge 1 , Also clearly visible is the deformation of the bellows 30 according to the height offset.

11 shows a view of the bridge 1 with view in vertical direction 18 ie on the underside of the bridge 1 where a height and side offset between the end frame 10 given is. This situation occurs, for example, when the vehicle parts 2 . 3 go through two consecutive opposite turns, as z. B. in a lane change of a train, in which the train passes through a switch from a first to a second track is given. Between the curves, a short straight piece can be arranged. In addition, a height offset of typically 0-10 mm may occur. Also in this situation are the base plates 4 on the sliding plates 14 flat on.

12 shows the same situation in an axonometric view from above, in this perspective, the on the base plates 4 slidable bridge plates 6 are more recognizable.

Another change of position of the end frame 10 and the center frame 25 each other is caused by a roll of the vehicle parts 2 . 3 caused. This will twist the vehicle parts 2 . 3 around the longitudinal axis 13 a vehicle part 2 . 3 against each other by angles of a few degrees, typically by 2 ° to 5 °.

13 shows a detail axonometric view of a base plate 4 resting bridge plate 6 in such a situation. It can be seen here that the bridge plate 6 in the direction of its pivot axis 26 in three parts 28 is divided, with the parts 28 independently of each other about the pivot axis 26 can swing. In contrast to a one-piece bridge plate 6 This avoids it in the direction of the pivot axis 26 to a clear lift of the bridge plate 6 from the associated base plate 4 comes. By dividing into several parts 28 each part is at least one place on the base plate 4 on, and there is a significantly lower withdrawal of each part 28 from the base plate 4 along the direction of the pivot axis 26 , It thus becomes a possible continuous concern of the bridge plate 6 on the base plate 4 scored even with shaky.

14 represents an axonometric view of a center frame 25 and an end frame 10 when coupling the vehicle parts 2 . 3 This results in the normal operation of the smallest distance 37 between end frames 10 and middle frame 25 in the passage direction 9 , where end frame 10 and middle frame 25 parallel to each other. This smallest distance 37 is typically between 290 mm and 340 mm, with maximum distances during normal operation 37 between 550 mm and 500 mm.

15 shows a side sectional view of the bridge according to the invention 1 at a minimum distance 37 , In this situation, the end area of the bridge plate 6 with the sliding coating 36 completely over the base plate 4 slipped, so that the sliding coating 36 already on the hinged band 27 the base plate 4 to come to rest. The base plate 4 again, in this situation, the hinged band touches 27 the bridge plate 6 just not. Typically, in this situation, the direction of passage is 9 measured distance between the hinge band 27 the bridge plate 6 and the base plate 4 between 0 and 10 mm.

An accident situation can lead to a further reduction of the distance 37 between end frames 10 and middle frame 25 to lead. 16 shows a view of the bridge 1 with view in vertical direction 18 ie on the underside of the bridge 1 ,

17 shows an associated side sectional view. The bridge plate 6 is with its end, which is the sliding coating 36 has, over the hinge strap 27 the associated base plate 4 slipped off and preferably in a designated area (not shown) in a vehicle part 2 . 3 penetrated. In this way will be a further reduction of the distance 37 between end frames 10 and middle frame 25 possible, typically 220 mm to 170 mm. The base plates 4 be in this situation, as in 17 represented, bent or deformed.
