Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor structure of a railway car carriage, a railway car carriage including the railway carriage, and a floor structure of a railway car,

The present invention relates to a carrier element constituting the bottom of a railway car carriage and a floor structure of a railway car carriage. The present invention also relates to a railway car carriage.

In railway vehicle engineering, there is a growing demand for internal fitting-out of railway vehicles. Generally, rail vehicles have two different passenger ratings, referred to as first class and second class. Fitting-out is performed more and more to provide a large-capacity carriage. Generally, the arrangement of the passenger seats is implemented in the form of one, two or even three seats on the left and right of the center passage formed in the large-capacity carriage. The large-capacity carriage can have a table between passenger seats facing each other.

DE 10 2006 032 333 B4 and EP 1 880 914 A1 disclose a floor structure of a railway car carriage having a longitudinal beam which is a bendable steel line formed in the longitudinal direction of the vehicle, The seat foot portion is fixed, and the floor panel is supported on the longitudinal beam. Each longitudinal beam forms a preassembled unit with an elastic material that is secured to the carriage body.

DE 10 2007 036 670 A1 discloses a floor structure of a railway car carriage comprising a plurality of metal rails for securing seats and floor panels. Wherein the inner profile is supported through an elastic element on an outer profile secured to the carriage body shell.

EP 1 112 206 B1 discloses a bottom structure having coupling elements for acoustically separated fastening to a floor anchor.

A variant solution is provided in DE 101 26 404, in which the double seat is completely fixed to the side wall.

KR 10-2009-0015499 provides for securing the seat to the bottom rail and the side wall rail.

NL 1003636 C2 discloses a bottom structure having dual C-shaped rails.

These solutions have the disadvantage that, for example, the lateral load shift occurring during normal use of a passenger seat can only be accommodated to a limited extent. Further, the above-described solutions permit changes to the seating arrangement, for example, only within a narrow range. Moreover, covering the rails is required to cover the transition of the bottom lining, so that the bottom lining is not continuous.

It is therefore an object of the present invention to provide a bottom structure having a rigid shape while permitting a variable configuration of the seat arrangement.

The above object is achieved by a floor structure of a railway car carriage according to claim 1; A carrier element constituting the bottom of the railway car carriage according to claim 12; A railway vehicle carriage according to claim 18; And the method for assembling the floor structure of another railway car carriage according to claim 19. Other embodiments, modifications and improvements will be apparent from the following description and the appended claims.

In one embodiment, which may be combined with other embodiments disclosed herein, the floor structure of a railway vehicle carriage may include at least one carrier element formed in the longitudinal direction of the railway vehicle carriage and secured to the carriage body shell of the railway vehicle carriage Wherein the carrier element is secured to a supply unit such as a passenger seat and a foot bracket of the table, the carrier element including a laterally outwardly directed shoulder surface for supporting the first floor panel. Wherein the carrier element is covered by a second floor panel disposed between adjacent first floor panels supported by the carrier element and at least some of the second floor panels are spaced apart from each other in the longitudinal direction of the railway car carriage So as to make the carrier element accessible to secure the foot bracket of the supply unit to the carrier element.

Accordingly, the floor structure includes two types of floor panels. The first floor panel is supported on the outer shoulder surface of the carrier element, but leaves the carrier element substantially free. Alternatively, the second floor panel covers the carrier element, so that the second floor panel is disposed between the first floor panels. The first floor panel is spaced from each other when viewed in the lateral direction. Alternatively, in the longitudinal direction, the first floor panels may be adjacent to each other or in some other suitable way to form a continuous floor. Thus, the first floor panel forms a continuous bottom in the longitudinal direction of the railway car carriage, and in each case one "duct" or intermediate space is provided between the first floor panels on the carrier element exist.

The second floor panel is provided to cover the "duct" or intermediate space, and the second floor panel is different from the first floor panel, for example by thickness and fixed type. Generally, however, the second floor panel, which is located in the intermediate space, is arranged in the longitudinal direction so as to ensure access to the carrier element for the fixing of one supply unit, for example a single seat or a double seat, Respectively. The intermediate space between the longitudinally spaced supply units is covered by a second floor panel extending transversely to the first floor panel to realize a continuous floor. Generally, the first and second floor panels are designed to form a step-free bottom.

For example, if it is desired to change the layout for the seating arrangement, for example, to change the separation distance (also referred to as "seating pitch"), between the seats of longitudinally adjacent railway cars, lift up said second floor panel, It is only necessary to replace the supply unit and insert a new second floor panel adapted to the seat pitch thus changed.

In one embodiment, which may be combined with other embodiments disclosed herein, the first floor panel supported on the shoulder surface of the carrier element comprises a step formed in the longitudinal direction of the railway car, in each case And at the edge facing the carrier element, the second floor panel covering the carrier element is supported on the step.

Thereby, an overlap is made between the first and second floor panels, firstly to provide an improved connection between the floor panels, and secondly to ensure that the upper part of the floor panel is coplanar with each other . Here, the height of the stepped portion may correspond to the thickness of the second floor panel. Moreover, the arrangement allows sealing of the bottom against the inflow of dust and liquid. This can be further improved through the use of suitable seals.

In one embodiment, which may be combined with the other embodiments disclosed herein, the carrier element comprises two or more profile rails formed in the longitudinal direction of the carrier element and spaced apart from each other in the transverse direction of the carrier element, Wherein the foot bracket of the supply unit is fixed to the two or more profile rails.

In one embodiment, which may be combined with the other embodiments disclosed herein, the carrier elements are formed in the longitudinal direction of the carrier elements, and in each case three profile rails spaced apart from one another in the transverse direction of the carrier elements Such as a C-shape profile, and each foot bracket is secured to two or more profile rails of the carrier element.

As discussed in detail above, the carrier element may comprise up to two or three profile rails. Generally, the bottom has carrier elements of the same configuration. Here, for example, two longitudinally spaced apart carrier elements are possible for use in a railway car carriage, the carrier elements extending through the entire passenger compartment of the railway car carriage. Each carrier element may be in a completely continuous form in the longitudinal direction or may be composed of separate longitudinal segments connected to one another.

In one embodiment, which may be combined with the other embodiments disclosed herein, the profile rail of the carrier element is disposed entirely below the second bottom panel. The profile rail is only covered by the second floor panel, not by the first floor panel.

In one embodiment, which may be combined with other embodiments disclosed herein, a floor lining is disposed on the first and second floor panels, and the floor lining comprises a first floor panel that covers one or more first floor panels in each case Wherein the bottom lining comprises a second surface portion covering each of the one or more second floor panels in each case and the edges of the surface portions are connected to each other in a sealed manner without overlapping.

Thus, the bottom lining can be placed edge-to-edge without the need to cover the rails and the like. Thus, a continuous surface is possible.

In one embodiment, which may be combined with the other embodiments disclosed herein, the floor structure is spaced apart from one another in the transverse direction of the railway car carriage and is formed in the longitudinal direction of the railway car carriage, Wherein the carrier element is secured to the foot bracket of the supply unit and at least some of the first floor panels are supported on both carrier elements.

In one embodiment, which may be combined with other embodiments disclosed herein, the carrier element (s) are secured to a beam that belongs to the carriage body shell through an elastic seat for acoustic isolation.

In one embodiment, which may be combined with other embodiments disclosed herein, a C-shaped bracket is secured to the beam belonging to the carriage body shell. An elastic seat in a generally C-shaped configuration is located within the C-shaped bracket to be supported against the inner wall of the C-shaped bracket, the resilient seating having an engagement web of a stationary element releasably connected to the carrier element, Or receiving grooves connecting the engagement bars.

The C-shaped bracket is coupled around the resilient seating portion to retain the resilient seating portion and the securing element. The fastening element can be inserted into the C-shaped bracket longitudinally with its mating web. The carrier element is then positioned on and preferably screwed onto the stationary element.

In one embodiment, which may be combined with the other embodiments disclosed herein, the foot bracket of the supply unit comprises, in each case, one support beam fixed to either the carrier element or one of the carrier elements, And a cladding or cover surrounding the first and second floor panels.

The support beam constitutes an actual fixation to the feed unit and is mounted in an appropriate manner on the profile rail. The cladding surrounds the support beam, thereby cladding any of the cable terminals of the carrier structure and the supply unit. The cladding also covers an area of the carrier element remaining free by the first and second floor panels. The region left open is located below the supply region. To make a sealed cladding, the cladding is seated on the bottom panel and additional seals can be provided.

In one embodiment, which may be combined with other embodiments disclosed herein, the second floor panel is releasably secured to the carrier element (s). Thus, the second floor panel can be easily removed for inspection purposes or during a switching operation.

In one embodiment, which may be combined with the other embodiments disclosed herein, the feeding unit may be provided with one or more carrier elements in a non-positively locking manner (forced fit) only by the foot bracket And the foot bracket is removable and / or displaceable. Fixing to the wall beam is not necessary.

In one embodiment, which may be combined with other embodiments disclosed herein, a floor of a railway vehicle, formed in a longitudinal direction and having at least one profile rail provided for securing a feed unit, e.g., a passenger seat and a foot bracket of a table, A carrier element for the structure is proposed, and the carrier element can be fixed to the carriage body shell of the railway car carriage. Characterized in that the carrier elements comprise two or more profile rails, in particular C-shaped profiles, formed in the longitudinal direction of the carrier elements and spaced from one another in the transverse direction of the carrier elements, between the profile rails, At least one cable duct is formed in the longitudinal direction, and the profile rail has a seating surface that supports the foot bracket when the foot bracket is mounted on the carrier element.

The profile rail of the carrier element allows free adjustment of the spacing distance of the supply unit in the longitudinal direction of the railway car carriage. Since the profile rails are spaced apart from one another in the transverse direction and enable both fixing of the supply unit, a high lateral load, which takes place during use of the passenger seat, is reliably received by the carrier element and dispersed into the support structure of the railway car . Here, the foot bracket of the supply unit makes a non-positive locking contact (forced fit contact) with the seating surface of the profile rail. Generally, the foot bracket is secured to the seating surface in a non-positive locking manner by a suitable fastening element, e.g., the foot bracket being fixedly threaded to a slide block or slide rail located within the profile rail. Thereby, it is possible that the supply unit is fixed only to the carrier element. Further fixation of the side wall beams of the carriage body shell is no longer necessary.

Further, the entire electrical cable can be received in said cable duct formed between two profile rails below the floor. Here, the cable duct may be opened upward. This facilitates the switching operation during certain changes to the layout of the seating arrangement.

Overall, the use of the carrier elements disclosed herein provides a significant degree of freedom in configuration and variability within the rail vehicle carriage.

In one embodiment, which may be combined with the other embodiments disclosed herein, the carrier element, when viewed in a transverse direction, comprises one lateral outwardly facing shoulder surface for supporting the first floor panel, Adjacent to the rail.

For example, the shoulder surface supports a fixedly mounted floor panel, in which a detachable connection may be used. The floor panel may be referred to as a first floor panel. The shoulder surface may be recessed relative to the seating surface, i.e., lower than the seating surface in a state in which the carrier element is installed. In general, the first floor panels lie with their edges on the shoulder surface, and each carrier element supports two or more floor panels. Viewed in the lateral direction, the first floor panels are spaced apart from each other, in particular the two profile rails and the cable ducts are free.

In one embodiment, which may be combined with the other embodiments disclosed herein, the carrier elements are formed in the longitudinal direction of the carrier elements, and in each case three profile rails spaced apart from one another in the transverse direction of the carrier elements , In particular a C-shaped profile, between which one cable duct is formed in each case in the longitudinal direction of the carrier element.

In the above embodiment, three profile rails spaced apart from one another in the transverse direction are provided to secure the passenger seats, giving an additional degree of freedom to the configuration for the layout of the interior rooms. The feed unit, for example a passenger seat, can be fixed to e.g. two outer profile rails. The outer profile rails are suitable, for example, for securing against double seats, since they are at the greatest distance from one another and thus provide the greatest capacity to accommodate lateral loads. Alternatively, one of the two outer profile rails can be used with the intermediate profile rails to secure separate seats, resulting in lateral variability.

Further, in the above embodiment, two cable ducts are provided which are spatially separated from each other by, for example, intermediate profile rails. As a result, the cable conducting the current can be placed separately from the cable conducting the signal, thereby improving safety and reducing interference. This is basically possible if a single cable duct is used if the cable duct has two or more separate chambers. The chamber can be easily fabricated by means of suitable compartments which can be provided integrally in the cable duct or can be manufactured by a suitable insert which is subsequently positioned within the cable duct.

In one embodiment, which may be combined with the other embodiments disclosed herein, the carrier element comprises, in each case, one inwardly facing shoulder surface for securing and / or supporting a second floor panel covering the profile rail Adjacent the outer profile rails.

In addition to the outwardly directed shoulder surfaces (also referred to as "outer shoulder surfaces") which are generally provided only on the outer profile rails, the carrier elements further have an inwardly directed shoulder surface . The inner shoulder surface may, for example, be provided only on the outer profile rail. The inner shoulder surface may also be provided on the intermediate profile rail.

The inner shoulder surface supports a floor panel that can be designed to be easily removable. The floor panels (also referred to as "second floor panels" or "variable floor panels") function to cover the carrier elements between longitudinally adjacent supply units. During any inspection that may be required or, for example, upon switching of the seating arrangement, it is only necessary to lift the second floor panel to access the carrier element. Alternatively, the first floor panel need not be separated. Accordingly, the first floor panel may be referred to as a fixed floor panel. However, it is obvious that the second floor panel also needs fixing. However, this may conveniently be produced by a hook-and-loop fastener or by a releasable fastening means.

In one embodiment, which may be combined with the other embodiments disclosed herein, the carrier element is a piece, in particular an extruded profile. Accordingly, the profile rail having the shoulder surface may be integral. The carrier element may be formed entirely as a hollow profile having a plurality of chambers, wherein the profile rails and shoulder surfaces are integrally formed thereon. However, it is also possible for the carrier element to be composed of separate components.

In one embodiment, which may be combined with other embodiments disclosed herein, the cable ducts formed between and adjacent to the adjacent profile rails may be open at one side. Thereby, one or more cable ducts are easily accessible.

In one embodiment, which may be combined with other embodiments disclosed herein, a railway vehicle carriage has a variable seat layout and includes two carrier elements formed in the longitudinal direction of the railway vehicle carriage, Wherein the first and second bottom panels or the bottom structure as described above are supported on the carrier element and the supply unit is fixed to the carrier element in a removable and / or displaceable manner.

In one embodiment, which may be combined with other embodiments disclosed herein, a method of assembling a bottom structure may include:

- fixing at least one carrier element formed in the longitudinal direction of the carrier element and comprising two or more profile rails spaced apart from each other in the transverse direction of the carrier element, to a damping element on the carriage body base of the railway car carriage;

- fixing the first floor panel to the carrier element; And

- fixing at least one foot bracket of the supply unit to the carrier element,

First, the first floor panel is fixed to the carrier element adjacent the profile rail in the longitudinal direction of the railway car carriage;

The second floor panel is then fixed to the carrier element between the first floor panels in the longitudinal direction of the railway car, at least a portion of the profile rails in the longitudinal direction are free to be held, And the bracket is fixed at that position.

Generally, the foot bracket of the supply unit is fixed before the second floor panel is placed.

In one embodiment, which may be combined with other embodiments disclosed herein, a first surface portion covering at least one first floor panel and a second surface portion covering at least one second floor panel are cut to size, And the second floor panel, and the edges of the surface portion are connected to each other in a sealed manner without overlapping.

In one embodiment, which may be combined with the other embodiments disclosed herein,

- removing said second floor panel, said first floor panel being in place;

- releasing the foot bracket from the carrier element;

Displacing the foot bracket along the carrier element, or replacing the foot bracket;

- fixing said foot bracket displaced or replaced in said carrier element; And

- installing a second floor panel, the dimensions of the second floor panel being adapted to the spacing of the foot bracket fixed in the longitudinal direction of the railway car,

Lt; / RTI >

In one embodiment, which may be combined with other embodiments disclosed herein, first, the bottom lining is cut or cut at the edges of the first and second surface portions to remove the first floor panel; The floor lining surface portion aligned with the second floor panel installed is then applied; The edges (located at edge-to-edge) of the first and second surface portions of the bottom lining are connected to each other.

In addition, a cover or cladding may be further provided for each foot bracket, which surrounds the foot bracket in a longitudinal direction and covers the carrier element with a fixture. The cover is mounted after assembly of the foot bracket and is removed before the foot bracket is detached during the detachment process.

Overall, a very flexible configuration of the interior rooms is allowed. In particular, the seating arrangement can be changed in a short time without lifting the floor. If the seat pitch is changed, only the second floor panel needs to be removed. If, for example, the seat is changed from first class to second class and vice versa, the second floor panel may be held in place if the seat pitch is maintained and only the seat is replaced.

The carrier element allows the rows of seats to be fixed to the floor only by one foot, regardless of whether the seats are single, double or triple seats. Fixation to the carriage sidewall is not necessary.

The floor structure proposed herein allows a sealed design for the inflow of liquid and dust. Here, the floor area in the passenger compartment can be configured to have a generally uniform floor lining. It is not necessary to cover the profile or edge on the floor in the seating area and thus is not visible.

The predetermined electrical cable of the passenger seat can be placed under the floor in one or more cable ducts and can be conducted to the passenger seat via the seat foot. Therefore, the cables for the consumer and terminal are completely covered.

The carrier element permits acoustical separation of the bottom comprising the fixture from the carriage body shell and acoustical separation of the body itself.

Accordingly, the bottom structure proposed herein allows partial or total satisfaction of the following design requirements.

- permitting variable seating arrangements by means of a bottom bracket having rail-forming carrier elements in the floor area in the longitudinal direction of the carriage, to which the foot (seats, seating rows) of the passenger seats are fixed;

- ensuring a stable transfer of force to a load change from the seat or any desired row of individual seats to the floor bracket via the foot;

Achieve a sealed design of the floor area;

- Design the floor so that the cover is not visible.

Thus, the floor structure provides a clear solution to the collision between a slight outlay and a variable seating row arrangement requiring a continuously flat, uniform, and sealed floor lining.

The carrier elements and proposed bottom structures proposed herein can be used particularly for railway vehicle carriages, especially for local and interregional passenger transport and for cabin for high speed passenger transport.

1 to 3 show a bottom structure according to the first embodiment.

The carriage body shell 250 of the rail vehicle carriage is, for example, an integral design and can be made of aluminum. The interior area of the railway vehicle carriage may be comprised of a mass carriage with different passenger ratings. Seating arrangements shall be in the form of a row of seats including one seat, two seats, or optionally three seats on the left and right of the central passage. Optionally, a table can be provided. The floor structure described herein allows a very free layout.

The bottom structure 200 includes one or more carrier elements 100 that extend in the longitudinal direction of the railway car carriage. Here, the longitudinal direction and the transverse direction refer to the railway car carriage, and the longitudinal direction of the carrier element 100 corresponds to the longitudinal direction of the railway car carriage in the installed state. In this embodiment, the carrier elements 100 are spaced apart from one another in the transverse direction and in this case three C-shaped profiles 130, 132 with a C-shaped rail shape with the slot open upward . Here, the C-shaped profiles 130 and 132 form a profile rail. A stepped shoulder surface 115 is formed on the two outer C-shaped profiles 132. The shoulder surface 115, which is in the form of a hollow profile in the form of a box in the form of a flange, is in each case adjacent to the outer C-shaped profile 132 outwardly.

The carrier element 100 may be integrally formed with a plurality of appropriately formed hollow profiles to provide the carrier element 100 with the required stability, stiffness and strength. Generally, an aluminum extruded profile is used. In particular, it is sought to ensure the strength in the transverse direction. Here, the separate hollow profile has a common aspect, so that it may be suitable to be able to receive and transmit the load.

3, the carrier element 100 may be secured to the carriage body shell 250 in a hollow profile that forms the shoulder surface 115. In particular, Since the hollow profile of the shoulder surface 115 is farthest from each other when viewed in the transverse direction of the railway car carriage, the maximum capacity to accommodate loads in the lateral direction becomes possible. Also, by being structurally fixed in the immediate vicinity of each outer C-shaped profile 132, direct delivery of the load is also ensured.

The carriage body shell 250 may be formed as an aluminum extruded profile and may have a base panel with two opposed walls having a transverse strut arrangement positioned therein. Thus, the base panel constitutes a carrier for the carrier element 100. On the base panel, a preferably integrally formed, inwardly directed C-shaped bracket 170 is formed. For each carrier element 100, two rows arranged in the longitudinal direction of the C-shaped bracket 170 are provided. Its spacing approximately corresponds to the lateral spacing distance of the shoulder surface 115. Alternatively, the C-shaped brackets 170 may be integrally formed on the base panel in a longitudinally continuous manner.

A rubber insert 160 for detachment is inserted into each C-shaped bracket 170. The rubber insert 160 constitutes an elastic seat in the present embodiment and may be formed in the manner of the support element disclosed in EP 1 112 206 B1. Also, the C-shaped bracket 170 may be designed as disclosed in EP 1 112 206 B1. EP 1 112 206 B1 filed on the construction of C-shaped brackets and rubber inserts is incorporated herein.

The rubber insert 160 couples the coupling web of the stationary element 150 and has a receiving groove in the form of a substantially H-shape in this embodiment. The stationary element 150 includes two webs 151, 153 that are integrally connected to each other by a transverse web 152. The web 153 has a curved end surrounded by a rubber insert.

The outer contour of the rubber insert 160 approximately corresponds to the inner contour of the C-shaped bracket 170, which has an angled inner surface and a generally concave inner surface and has sidewalls facing each other. The rubber insert 160 is supported on the inner surface to provide a locking action in the vertical and lateral directions. The rubber insert 160 and the securing element 150 can be inserted under pressure from the open side of the inner contour into the C-shaped bracket 170. Because the securing element 150 is releasably connected to the carrier element 100 during assembly, the securing element 150 with the rubber insert 160 is first inserted separately into the C-shaped bracket, The element 100 is fixedly screwed to the stationary element 150, for example. If height correction is required, an intermediate layer 118, for example in the form of an aluminum panel, may be inserted between the stationary element 150 and the carrier element 100.

The C-shaped brackets 170 can be disposed with a distance from each other in the longitudinal direction of the railway car. The distance between the longitudinally adjacent C-shaped brackets 170 and the length of the C-shaped brackets in the longitudinal direction can be adjusted according to the load received. Thus, the carrier element 100 is longitudinally fixed to the plurality of C-shaped brackets 170. [ As a result of the fixation of the carrier element 100 disclosed herein, acoustical and vibrational separation of the structure in the base region from the carriage body shell is achieved.

In order to prevent slippage in the longitudinal direction, spacers may be located between the inserted fastening elements 150, which keep the fastening elements 150 spaced apart from one another. The spacers can be clamped in a C-shaped bracket 170, for example in the form of a continuous rail, or can be fixedly clamped between longitudinally adjacent C-shaped brackets 170.

2 shows the floor structure at the bottom side, but for better clarity, the carriage body shell including C-shaped brackets is not shown.

The carrier element 100 shown in Figures 1 to 3 further comprises two cable ducts 120 which are laterally spaced apart by a central C-shaped profile and serve to guide the cable, The current conduction supply cable is guided separately.

Between the cable duct 120 and the profile of the outer C-shape in each case is provided an inner shoulder surface 134 which is used for securing the second floor panel 220 in this case. The inner shoulder surface 134 is flangedly attached to the sidewalls of the outer C-shaped profile 132 and then incorporated into the side walls of each cable channel. Thereby, a step is formed on the side of the profile of the outer C-shape. The inner shoulder surface 134 is recessed downward with respect to the seating surface 131 of the C-shaped profiles 130 and 132 but not up to the outer shoulder surface 115.

As a result of the configuration with two upwardly open cable ducts 120 and a C-shaped profile 130 disposed therebetween, the carrier element 100 can be referred to as a W-shaped in cross-sectional view , W are formed by an outer C-shaped profile 132. The outer C- The two outer C-shaped profiles 132 may be spaced approximately 20 cm to 30 cm in the transverse direction relative to their respective centerlines. If a relatively high lateral load is predicted, the spacing can be adjusted accordingly.

The carrier element 100 is formed as a hollow profile with a generally reinforcing inner wall between the hollow profiles forming the shoulder surface 115. The C-shaped profiles 130 and 132 are integrally formed thereon. This results in a very rigid and stable carrier element 100 as a whole.

The slide block 140 is inserted into the C-shaped profiles 130, 132. For the securing of each passenger seat for each C-shaped profile, one slide block 140 with two inner threads is used. The length of the slide block 140 is adapted to the required strength and load capacity. In the embodiment shown here, the slide block 140 is located only in the profile 132 of the outer C-shape and is provided here for securing the double seat. For single seats, it is sufficient that one outer C-shaped profile 132 and an intermediate C-shaped profile 130 are used. Accordingly, the single seats can be laterally offset by the separation distance between the central C-shaped profile 130 and the outer C-shaped profile 132.

The first floor panel 210 is seated on the outer shoulder surface 115 of the carrier element 100. The floor panels are suitably fixed, for example, by adhesive bonding or screws. As can be seen in FIG. 3, the first floor panel 210 may be a multi-layered structure. Here, an edge layer or cover layer 211 which serves as a carrier layer and rests on the shoulder surface 115 is provided, if appropriate by means of a height compensating element or damping element 117, for example a rubber seat.

The edge or cover layer 211 may be, for example, a birch plywood panel. Below the edge layer or cover layer 211 is an additional layer (which may be an insulating layer or an integral bottom heater) that is spaced from the edge of the edge layer or cover layer 211. In addition, an insulating layer 174 may be attached to the bottom surface of the carrier element 100.

The upper side of the edge layer or cover layer 211 may be aligned with the bottom lining 213. As can be seen in Figures 1 and 3, the first floor panel 210 has, at their edges towards the carrier element 100, one step 212 formed in each case in the longitudinal direction , The depth of the step substantially corresponds to the thickness of the second floor panel 220. Accordingly, the second floor panel 220, which is thinner than the first floor panel 210, is placed on the first floor panel 210 at the stepped portion, . Likewise, the second floor panel 220 can be aligned with the bottom lining 223.

In addition, the second floor panel 220 is seated on the seating surface 131 of the C-shaped profiles 130, 132. The inner shoulder surface 134 has the function of securing the second floor panel 220 securely with a corresponding hook-and-loop strip applied to the bottom surface of the second floor panel 220 And may be aligned with a hook-and-loop strip 135. The second floor panel 220 is prevented from sliding laterally by the first floor panel 210 which is fixedly mounted. Alternatively, the second floor panel 220 may be secured to the carrier element 110 by a clip that can be snapped into a C-shaped rail. In addition, shoulder surface 134 may be aligned with resilient seating portion 135, which allows height correction in this case.

Because the first and second floor panels 210, 220 have different thicknesses, the outer and inner shoulder surfaces 115, 134 are disposed at different heights to allow different thicknesses.

The first floor panel 210 is aligned with the first surface portion 213a of the floor lining 213. [ Alternatively, the second floor panel 220 is aligned with the second surface portion 223a of the floor lining 213. The edges of the surface portions 213a and 223a are placed edge-to-edge and are connected to each other in a non-overlapping and sealed manner to form a continuous bottom surface.

It can be seen in FIG. 2 that the first floor panel 210 is beveled at an edge that is formed in the transverse direction to slightly overlap with each other. Alternatively, tongue-and-groove connections are also possible. This allows mutual overlap and support between all floor panels 210, 220, thereby permitting a sealed shield against dust and moisture. Additionally, sealing adhesive bonding may be used.

The area between the assembled passenger seats is covered by the correspondingly cut second floor panel 220 to dimension longitudinally and the area for securing the passenger seat is free to rest.

All floor panels, i.e., the fixed first floor panel 210 and the adjustable second floor panel 220, are covered with a continuous plastic floor lining. The bottom lining of the second floor panel 220 is sealed and welded to the bottom flooring of the first floor panel 210.

The entire floor area is divided into three sections 710, 720, 730 formed in the longitudinal direction. This can be seen, for example, in FIG. One of the first floor panels 720 is positioned between the carrier elements 700, shown schematically in cross-section, only schematically, which is formed in the longitudinal direction of the railway car carriage and forms left and right seat rows . The other two first floor panels 710 and 730 are located in each case between the left and right side walls 740 and the nearest carrier element 700. The first floor panels 710, 720, 730 are spaced apart from each other in the area of the carrier element 700. Here, the bottom is formed by the second floor panel 750.

The securing of the passenger seat is shown, for example, by Fig. Fig. 4 shows a rough cross section along line BB ', while Fig. 3 shows a rough cross section along line AA' in Fig. The foot bracket 280 includes a support beam with a carrier panel 281 that is connected to the slide block 140 by a threaded connection 284 to connect the carrier panel 281 to a C- Particularly on the upper seating surface 131 of the outer C-shaped profile 132. [0064] Here, the carrier panel 281 is also placed on the intermediate C-shaped profile 130.

The carrier panel 281 is connected to a support beam or support 282 that is supported against the carrier panel 281 by one or more ribs 283, e.g., four ribs. The cladding 285 of the foot bracket 280 is shown in dashed lines. The cladding 285 is seated on the first floor panel 210, thus closing the openings that remain freely between the floor panels. In addition, the cladding 285 also rests on the second floor panel 220 to block the opening therefrom.

In the case of changing the layout of the seat row and / or the passenger seat and / or the table, the weld point between the first floor panel 210 and the second floor panel 220 is cut and, if appropriate, The floor panel 220 is removed. If only the inspection is performed, it is sufficient that only the cladding 285 of the foot bracket 280 is removed. Thus, access to the foot bracket 280 and the cable is provided. After a change to the layout is performed, a new second floor panel 220 is inserted, possibly matched to the changed seat pitch.
