Description

Rail vehicle with a sound and vibration isolated room-in-room cabin

The invention relates to a rail vehicle with a room-in-space cabin with improved sound and vibration isolation.

Modern trains, especially high-speed trains, must meet high standards of ride comfort, including the lowest possible noise level in the interior. Often, passenger areas in the end cars are placed directly behind the driver's cab above the bogies equipped with drive components. In addition, it comes at very high speeds to aeroacoustic suggestions. As a result, the requirement for good sound insulation is particularly evident.

In the prior art, various measures are described how the noise level in the passenger compartment of a rail vehicle can be reduced.

A previously used measure is to line the space between the floor of a compartment and the car body with sound-absorbing material, such as mineral wool, in order to reduce the sound input on the Fu ßboden. Furthermore, the space between the inner side wall of a compartment and the

Car body side wall lined with sound-absorbing material. Furthermore, it is possible to realize the sound insulation by using heavy inner floors and the use of damping pads on the car body shell.

WO 01/05640 discloses a connecting element for connecting a wall and an extension part of a car body, which has a rubber-elastic support member. In addition to the suspension properties, noise-absorbing properties of the support part are also utilized, whereby a low introduction of structure-borne noise into the interior of the car body of a vehicle is to be provided.

However, these known solutions for reducing the noise level in passenger spaces are considered to be insufficient for modern rail vehicles, especially high-speed trains, since a very strong sound and vibration entry occurs in the vehicle interior especially in the bogie. The invention was therefore based on the object to provide a rail vehicle having an improved sound and vibration isolation. In particular, the sound entry and vibration entry should be reduced in a passenger cabin from the bottom, for example on the bogies.

For this purpose, the invention proposes a rail vehicle with the features of claim 1. Advantageous specific embodiments are specified in the subclaims.

The present invention relates to a railway vehicle with sound and

vibration-insulated cab, with

a carbody, having

a carbody floor,

Cart body side walls and

a wagon deck, and

a cabin enclosed by the car body, comprising

Cabin side walls

a cabin ceiling, and

a rigid floor pan, comprising a bottom part and side parts

the cabin being on one or more, between the floor pan and the

Car body floor arranged spring elements is mounted.

The vehicle has a space-in-space structure. The cabin is arranged as a separate space within the car body. The term "cabin" means a space inside a railway vehicle, preferably for the purpose of residing in. Persons covered by the term "cabin" include, without limitation, driver's cabs,

Passenger compartments, open-plan cabins, etc. Examples of rail vehicles are, without limitation, wagons, locomotives and railcars.

According to the basic idea of the invention, the lower region of the cabin is formed by a rigid base trough which is mounted on spring elements, wherein the

Spring elements are arranged on the body floor and the bottom tray is mounted on the spring elements. The cabin side walls connect directly or indirectly, for example via fasteners, to the floor pan and continue the cabin upwards. The spring elements absorb the weight of the floor pan and most of the weight of the cabin. The floor pan is stiff or substantially rigid, meaning that under load it shows no or minimal warping or twisting.

The floor pan is preferably also in a specific embodiment

self-supporting.

The bottom pan has a relatively high mass compared to, for example, the sidewalls, which increases its inertia and reduces its natural frequency while maintaining rigidity. Due to an increased mass and thus reduced natural frequency of the floor pan, the vibration isolation wideband, since the insulation starts from a frequency f of f = (2) ^{1/2 *} natural frequency.

The natural frequency of the well is preferably in the range of 20-100 Hz,

more preferably 20-50 Hz and most preferably 20-30 Hz, the

Natural frequency under base load, i. without passengers in the cabin, meaning.

The mass of the floor pan and the static base load (without passengers staying in the cabin) can, for example, be increased by arranging, for example, support elements, air ducts, storage cabinets and / or electrical operating elements in the side parts of the floor pan. Carrier elements and air channels may e.g. Made of metal. In addition, or instead, the mass of the floor pan may be increased by having the bottom part of the tub comprise a plurality of layers of solid material, e.g. Layers of wood, in particular plywood, or metal.

Finally, the mass of the floor pan can also be increased by putting on the

Floor part cabin side interior furnishings are arranged, such as chairs and / or tables.

The rigid floor pan is decoupled in the enclosed space of the car body and has no rigid connection to the floor, walls and ceilings of the car body. The cabin is mounted on spring elements. As mentioned, the tub is in itself supporting. The spring elements cause a sound and vibration isolation of the cabin, especially in the area of the floor pan, and especially in the field of Fu ßbodens.

The load of the cabin side walls rests at least partially, preferably predominantly, on the floor pan. As a result, static load of the cabin side walls in the vertical direction via the spring elements on which rests the floor pan, be dissipated.

The spring elements also have damping properties in one embodiment, so that they are at the same time spring and damping elements. In other words, in one embodiment, the spring elements are also damped. Vapor properties of the spring elements depend on the choice of material, for example on the type of

Plastic, when the spring elements are made of plastic.

An attenuation causes an increase in the resonant frequency of the bottom pan is avoided or at least limited when an excitation in the field

Resonant frequency occurs.

In one embodiment, additional damper elements are disposed between the floor pan and the carbody floor. In this embodiment, the cab is supported on one or more spring elements disposed between the floor pan and the body floor and one or more damper elements disposed between the floor pan and the body floor. The

Spring elements and the damper elements are mutually different in this embodiment, preferably spatially separated elements.

In a special variant of the invention, the spring elements, and if present the additional damper elements, exclusively between the bottom part of the

Floor pan and the car body floor arranged so that only the bottom part of the floor pan rests on spring elements.

The side panels of the floor pan, in one embodiment, have one or more acoustically decoupled connections to their adjacent carbody sidewalls. The compounds may have elastic connecting elements, which are made of rubber, for example. The side parts of the floor pan have in a further, specific embodiment, no connection to their adjacent car body side walls, in particular no attachment to adjacent car body side walls. Optionally existing stop elements, as described below, which are preferably non-contact, are not a connection. Thus, the side parts of the floor pan preferably have no connection to the surrounding car body. By avoiding connection between the side parts of the floor pan and the respectively adjacent car body side walls of the lower area of the cabin is particularly well sound and vibration isolation and the sound entry into the lower area of the cabin, for example, by sound from the bogies even better reduced.

The term "no connection" means, in particular, that there are no fastening elements, connecting elements or connecting components that could transmit vibrations or sound. In particular, there are no rigid or elastic fastening elements or connecting elements that are able to transmit vibrations or sound However, space between the lower portion of a cabin sidewall and an adjacent body sidewall may, if desired, be non-vibratory, preferably loosely packed

Isolation material may be arranged, such as mineral wool.

In a specific embodiment, the floor pan is floating to the

Car body floor stored. A floating bearing means that the bottom part of the floor pan and the body floor are not firmly connected to each other, neither via the spring elements nor through other connections. Thus, the

Floor pan relative to the body floor theoretically in every horizontal

Spatial direction displaceable. But a shift is on the one hand by the

Dead weight of the floor pan and the cabin, frictional forces between the

Floor pan and the spring elements and the car body floor practically prevented. In addition, stop elements may be present, which prevent a displacement of the cabin.

The floating storage can be carried out in various ways. The spring elements, for example made of elastomeric material can be fixed to the bottom part of the floor pan or on the car body floor, for example by

Screw on or stick on. By contrast, the bottom pan, in particular the bottom part, not fixed to the spring elements. In a further variant, it is also conceivable to arrange the spring elements without any fixing between the bottom part of the floor pan and the car body floor. The spring elements are then held in place by the overlying weight of the tub.

In one embodiment of the invention, the cabin has no openings to a gap, which is located between the cabin and the surrounding car body, whereby the sound insulation is further improved. In the region of the windows, which are arranged in the car body, the cabin side wall, for example, projections to the outside, in the direction of the solid, and the edges of the projections are fixed to the wall of the car body or the window frame. In other areas, seals may be present.

Between the side wall of the floor pan and the car body side wall so-called stop elements can be arranged. The stop elements cause a support of the floor pan in the x and y direction, in particular with lateral forces and forces in the vehicle longitudinal direction. The x-direction is the direction of the longitudinal axis of the carriage and the y-direction is the direction transverse thereto, to the side of the carriage. The Z direction is upwards. Preferably, said stop elements are arranged at the level of the upper edge of the side wall of the floor pan. The

Stop elements may for example be designed as opposite each other in the longitudinal direction of the car straps, wherein a first tab on the

Car body side wall is attached and a second tab on the side wall of the floor pan, in particular at the level of the upper edge of the side wall. The

Stop elements, in particular the tabs, are preferably arranged so that they only touch each other (strike) when the bottom pan is moved over a certain distance relative to the car body, for example, during braking of the car, and that they are otherwise non-contact. In order to damp the abutment against each other, an elastic material may be provided between the tabs, which is attached to one of the tabs.

A rigid, self-supporting tub can be made by any rigid assembly of a bottom part and side parts. A joint connection can be made by all commonly used in rail vehicle joining techniques, but in particular by screws or welding. Alternatively, the tub can also be made in one piece. According to the invention form the bottom part and at least the said side parts in a rigid tub. In the rigid, self-supporting construction but may also be included parts of the cabin side walls.

By the bottom part is meant the lower, horizontally or substantially horizontally extending portion of the floor pan. The bottom part can be made up of several layers. As materials for the bottom part or the various layers of the bottom part are preferably metal, wood, such as

Plywood, and / or plastics used. Individual layers can be glued together. In particular, sound-insulating materials may be arranged between layers of wood, e.g. porous or non-porous plastics, cork, or mixtures thereof. As the last layer towards the interior, a carpet or a plastic covering is preferably applied to the bottom part. Thus, the bottom part in the direction of the inside of the cabin forms the cabin floor.

The side parts of the floor pan extend upwards both in the longitudinal direction of the cabin and from the bottom part. They can also be referred to as side walls of the tub. For example, the side panels begin at the in

Vehicle longitudinal direction extending edges of the bottom part. The side parts of the

Floor pan preferably extend maximally to the lower edge of the

Car window. The side parts of the floor pan take each, starting from the

Bottom portion, preferably up to 25% of the maximum interior height of the entire cabin, more preferably up to 30%, even more preferably up to 35% and most preferably up to 40%.

In one embodiment, the side parts of the floor pan on carrier elements. The support elements give the side panels a rigid and self-supporting structure. In a special embodiment, the side parts have carrier elements which extend from bottom to top. Furthermore, the side parts may also have cross member elements which extend in Wagenkastenlängsrichtung. In particular, the side parts may have a self-supporting skeleton structure of carrier elements.

At least some of the support elements of a skeleton structure are preferably connected to each other. In particular, support elements that run from top to bottom may be connected to carrier elements which extend in the longitudinal direction. The carrier elements can be all types of carriers. An example are profile beams, preferably made of metal. Such a rigid and self-supporting structure can be covered at least in the direction of the interior with cladding elements, such as screens.

In a specific embodiment, at least a part of the carrier elements are at the same time air channel elements. In this embodiment, at least a part of the support elements has a dual function as a supporting element and as an air channel for the ventilation system of the cabin. Air duct elements form part of the ventilation system of the cabin and form part of an air duct for introducing air into the cabin.

Carrier elements, which are at the same time air duct elements, have a cavity in the interior with two openings, wherein first opening may be provided as an inlet opening for air and another opening as an outlet opening for air. The

Air duct element is preferably tubular, so that the cavity in the

Air duct element is a tube. The tube can be any, even within one

Air duct element have varying cross-sections. The cross section can

for example, round, oval, or polygonal, for example rectangular. The

Air duct element may be bent, wherein the bend is preferably adapted to the contour of the car body. The air channel elements may have at their ends a flange for connection to other components. Preferably

Air duct elements, in particular tubular, of metal. The air channel elements preferably extend from bottom to top, from a lower end of the

Side of the floor pan to an upper end of the side part. Air channel elements with a tubular cavity have a high rigidity, whereby they are particularly suitable as load-bearing elements. Furthermore, air duct elements may contribute to reducing the natural frequency of the floor pan by their mass, especially if they are made of metal. Along the side panels of the floor pan are

preferably a plurality of air channel elements arranged parallel to each other.

At the bottom, the above-described air duct elements may be connected to a running in the vehicle longitudinal direction of the hollow profile carrier, the

Air outlet openings may have, so that air passed through the air duct elements enters the hollow profile carrier and from the air outlet openings towards the interior is directed. The hollow profile carrier forms in this embodiment, the lower edge of the side parts of the tub and is placed on the bottom part of the tub. He thus forms a side member of the side part of the floor pan. On the upper side, a plate can be placed on the air duct elements and any other carrier present, which has air passage openings where the air duct elements are attached. At this openings further air channel elements can connect in the cabin side walls. The plate can be the upper conclusion of a

Form side part of the floor pan. The plate can protrude into the interior of the cabin and, for example, form the function of a shelf or sill for windows provided above in the cabin side walls. The plate can also be a longitudinal member of the side part of the floor pan.

Furthermore, operating devices for passengers, for example control devices for air conditioners, cabinets and / or storage compartments, may be provided in the side parts of the floor trays.

The side parts of the floor pan, in particular the advantageous embodiments described above, preferably have a greater thickness, i. a bigger one

Extension transverse to the vehicle longitudinal direction, on than those on the side panels

adjoining side walls. This is particularly the case when the side parts have a rigid, self-supporting structure of support elements, and especially when air duct elements are included. In particular, the side parts of the trough can protrude into the interior of the cabin, wherein the upper edge or the upper side of the side parts can form the function of a shelf or window sill.

Due to the resilient mounting of the trough on spring elements, the trough is deflected under static load, for example, by passengers in the cabin, down, the spring elements are compressed. Due to a high static base load, due to the mass of the floor pan (without passengers), results in a small additional compression of the spring elements at maximum load by passengers. In other words, the mass of the floor pan significantly exceeds the mass of passengers on the floor pan.

The cabin side walls arranged above the floor pan can be flexibly connected to the floor pan, as will be described below, so that upper Areas of the cabin side wall under load are not deflected equally as the floor pan.

In a rail vehicle, a plurality of the above-described bottom troughs can be arranged, which are preferably connected to one another by elastic connections.

Connections of the floor pan, in particular the bottom part of the floor pan to other floor sections, for example floors in the area of the driver's cab or in other car areas, or connections to partitions are preferably made elastic or with gaps between them to the

Floor pan, especially the bottom part of the tub, effective from others

To decouple Fu floor sections.

The cabin side walls may be constructed of several elements.

Cabin side wall elements, which are arranged in the region of the windows, are preferably stationary there, and in particular not arranged to be displaceable upwards or downwards. The cabin sidewalls attach to the upper edge of the side part of the floor pan. In the case of a multi-part cabin side wall, in particular, the part of the cabin sidewall, which includes the window cutouts, attaches to the upper edge of the side part of the trough.

The above the floor pan arranged cabin side walls can over

Suspension elements to be connected to their respective adjacent car body side wall. The suspension elements may, for example, be arranged above the windows and / or in the region of window columns. The suspension elements are preferably elastically movable and serve to fasten the side wall or, in the case of a multi-part side wall, the attachment of side wall elements, including possibly existing luggage racks. They thus allow an elastic movement of the cabin side wall relative to the adjacent car body side wall.

The spring elements for storage and support of the floor pan can

For example, be air springs, gas springs, elastomeric springs. In a preferred embodiment, elastomeric springs, hereinafter referred to as "elastic elements", are used. For example, the elements may be circular, rectangular or strip-shaped. For example, the elastic elements have a strip shape. You can

For example, be aligned along the longitudinal axis of the carriage (x-axis) or along the y-axis or obliquely thereto. The distance between the strips can

for example, in the range of 200 to 600 mm. The space between the strips may be lined with an insulating material, such as mineral wool, such as glass or rockwool, a plastic foam, damp-proofing materials, or a combination thereof. The strips can be attached to the body floor with an adhesive. Particularly suitable materials for the elastic elements are elastomeric plastics. Examples include natural rubber, synthetic rubber,

Polyurethane, polyether urethane, silicone rubber, with cellular / porous materials being particularly suitable. Most preferred materials are among the

Brand names Sylodyn®, SylodynNB® and Sylomer® distributed, for example, by the company Getzner.

The elastic elements also have a damping effect in a preferred variant

Properties are therefore preferably also simultaneously damper elements.

The elastic members preferably combine the properties of static stiffness and dynamic flexibility. When low-frequency

Resonance phenomena are to be reduced, a high damping of the elastic elements is advantageous, in particular for the reduction of low-frequency vibrations.

It is preferred to design elastic elements for the following properties, wherein one or more of the properties may be present:

Creep behavior / maximum thickness reduction of 5% over time,

preferably over a period of 10 years,

maximum 2 mm, preferably maximum 1 mm, deflection at a continuous load of up to 80 kg / m ² ,

a maximum of 2 mm, preferably a maximum of 1 mm, deflection with a short-term load of up to 320 kg / m ²

- resistance to shocks of 3g in the X direction (longitudinal), 1 g in the Y direction (transverse), 3g in the Z direction (up or down) In a specific embodiment, two different elastic materials, hereinafter referred to as first and second elastic material, are used. Here, the first elastic material exclusively, or predominantly, resilient

Properties and the second elastic material exclusively, or predominantly cushioning properties.

The cabin side walls and the floor pan may be connected to each other via an elastic connection. In other words, each cabin side wall may be connected via a resilient connection to the side parts of the floor pan. The

Cab side wall sets at the top of the side part of the floor pan, wherein between the lower edge of the cabin side wall and the upper edge of the

Floor pan the elastic connection is arranged. In the case of a multi-part side wall, in particular, the side wall part is connected via an elastic connection with the bottom pan, which includes the window cutouts.

The elastic connection can be carried out in various ways.

For example, it may be a joint or sealing strip made of elastic

Act material, or connectors or connection angle with rubber-elastic elements or the like. The elastic connection may also be an elastic strip or a resilient profile, which may have a sealing function.

In still another embodiment of the invention, the carbody floor has a car interior horizontal plate, a cart outer horizontal plate and cross struts connecting the two horizontal plates. Furthermore, in this

Embodiment the elastic elements on the car inner plate over

Connecting points of the cross braces to the car inner plate arranged. The

described structure of a car body floor, for example, by a

Profile element, such as an extruded profile, or more composite

Profile elements are formed with inner cross struts. In particular, it is preferable in this embodiment to use first elastic elements in strip form, which are arranged above the junctions of transverse struts in the vehicle longitudinal direction (x-direction). Usually, the cross struts described in

Vehicle longitudinal direction aligned so that the cross braces and the strip-shaped elastic elements have the same course and are substantially above each other, separated from the car inner plate. In this embodiment, the elastic elements arranged at particularly rigid locations of the carbody floor and one achieves a particularly effective elastic decoupling between

Car body floor and cabin floor.

The invention also relates to a method for sound and vibration isolation of a car of a rail vehicle, in which

in a car body, having a body floor,

Wagenkasten sidewalls and a car box ceiling, a cabin is arranged, which is enclosed by the car body and the cabin side walls has a cabin ceiling, and a rigid floor pan,

- the cabin on one or more, between the floor pan and the

Car body floor arranged spring elements is stored.

For the method, reference is made to all previously disclosed objects, including all previously described embodiments of a rail vehicle and a floor pan, so that the method in particular with the previously described

Objects can be combined.

Finally, the present invention also relates to a rail vehicle network, for example a train, which comprises one or more rail vehicles as before

has described.

Air channel elements 42 arranged parallel to each other, as shown in Figs. 6b and 6c.

The beams 42 have a dual function as a supporting element and as an air channel element for the ventilation system of the cabin. The formed air channel is designated 48. Air L may enter the carrier / air channel member through the opening 50 through an upper opening / inlet opening and is introduced into the hollow profile carrier 47 through an outlet opening 53. The hollow profile carrier 47 points in the direction of the cabin

Air outlet openings 49, which are shown in Figures 1 and 2. Thus, air passed through the air duct elements 42 enters the hollow profile support 47 and is directed out of the air outlet openings 49 in the direction of the interior. The inlet openings 50 of the air duct elements 42 are connected to the ventilation system of the cabin, in particular to further air ducts (see Fig. 6c). The air channel element 42 is tubular with a rectangular cross section, as shown in Fig. 6b. The air duct element is bent and the bend is preferably adapted to the contour of the car body. The air channel elements 42 have at their ends

Flanges 53, 54 for connection to other components, such as a top board 52 and the hollow profile support 47, on.

The carrier / air channels 42 have a high rigidity and a relatively high weight, especially if they are made of metal. Therefore, they contribute particularly to the mass and rigidity of the side part 1 1 and thus to the mass and rigidity of the bottom pan 6 at. Further support members 41 and 46, only a few of which are shown by way of example, also extend from bottom to top. The carriers 41, 42 and 46 extend between a lower plate 51 and an upper plate 52 which extend in the longitudinal direction of the side part 1 1 and thus in the longitudinal direction of the vehicle. The carrier 41 are additionally connected via angle 60 with the hollow profile carrier 47. Between

Carrier elements 41 are mounted on angle 45 longitudinally extending carrier 43.

Between the longitudinally extending supports 43, in turn, vertically extending supports 44 are mounted. The carrier 43 and 44 serve for a further stiffening of the side part 1 first In addition, they also serve in this particular embodiment for the attachment of comfort devices, such as magazine holders,

Storage compartments, cabinets, operating devices or the like. On the lower plate 51, a base 70 is mounted for a magazine rack.

The support elements described above, but in particular the carrier / air channels 42, give the side part 1 1 a rigid and self-supporting structure. The air channel elements 42 having a tubular cavity have a high rigidity and a relatively high mass, which contributes to the reduction of the natural frequency of the bottom pan. Towards the cabin cover plates 55 are attached to the supports 41 and 46 (see Fig. 6c).

As shown in Fig. 6a and 6b, at the top of the side part 1 1 on the

Air channel elements 42 and the carrier 41 and 46, an upper plate 52 is placed, which where the air channel elements 42 are attached, has openings, the

are congruent with the openings 50 of the air channel elements 42. At these openings close up further air channel elements 56 in the region of

Cabin side wall 8a, as shown in Fig. 6c. Fig. 6c shows the view cabin side walls 8a and 8c interconnected from the outside Shen, ie by the (not shown) car body side wall 4a toward the cabin interior. Visible are the sides of the cabin side walls 8a and 8c, which are opposite the car body side wall 4a.

The plate 52 forms the upper end of the side part 1 1 of the bottom tray. The side part 1 1 of the bottom pan has a greater thickness, i. a greater extent transverse to the vehicle longitudinal direction, on than the adjoining side wall 8a, as can be seen in Figures 1, 2 and 6c. The side part 1 1 together with the plate 52 protrudes into the interior of the cabin, as seen in Figs. 1 and 6c, and the plates 52 forms a shelf or sill for the window 13a provided above in the cabin side wall 8a. The side part 1 1, in addition to the upper plate 52 and a lower plate 51, which is arranged at the lower end of the side part and as the upper plate extends in the vehicle longitudinal direction. The upper plate 52 and the lower plate 51 take over because of their rigidity and a supporting function for the side part 1 1 of the bottom tray. Corresponding as stated above applies to the side part 1 1 mirror-symmetrical side part 12th

FIGS. 7a and 7b show an elastic connection between a cabin side wall and a side part of the floor pan in the region of the transition between two side wall elements 8a and 8c. Fig. 7a shows a detail from Fig. 6c in the region between the windows 13a and 13c, where two side wall elements 8a and 8c are interconnected. Fig. 7a shows how Fig. 6c shows the view

Cabin side walls 8a and 8c from the outside, i. by the (not shown)

Car body side wall 4a toward the cabin interior. In the lower part of Fig. 7a, a section of the side part 1 1 of the bottom tray with the air channel / carrier elements 42 and the upper plate 52 is shown. On the upper plate 52, an aluminum extruded profile 105 is placed and fixedly mounted on the plate 52. With the profile 105 car body tolerances can be compensated. Fig. 7b shows the structure in section transverse to the longitudinal axis of the vehicle, wherein the cabin space 1 is arranged on the left side. There it can be seen that the profile 105 opens on the left side of the cabin interior 1 in a hollow profile part, which in cross-section approximately

is quarter-circular. This hollow profile part forms the transition between the upper plate 52 and the side walls 8a, 8c and conceals the gap between the plate 52 and the side walls as a diaphragm. FIG. 7 a shows air duct elements 56 in the region of the cabin side walls 8 a and 8 c, which continue the air duct of the carrier / air duct elements 42 upwards and laterally, below the windows 13 a, 13 c. The air channel elements 56 sit with a flange or a projection 1 1 1 on the profile part 105. Between the projection 1 1 1 and the profile part 105, an elastic sealing layer is arranged, which is not shown in this figure. This elastic sealing layer, for example, an elastic sealing foam is an elastic connection between a cabin side wall and a side part of the bottom trough, which allows the side part of the

Floor pan relative to the wall parts, in the area of the windows relative to

surrounding carbody are fixed, and relative to the air channel elements 56 which are fixed to the wall parts can move, e.g. with a movement of the tub in the Z direction down.

The connection between the side walls 8a and 8c is explained with reference to FIG. 7b. A here in cross-section hat-shaped profile 101 covers as cover the slot between two side wall portions 8a and 8c. It can, for example, with a

Adhesive or Velcro fastened to the side wall parts. In Fig. 7b is a section through the center of the profile 101 is shown, approximately at the level of

Connecting line of the walls 8a and 8c, where the profile is spaced from the walls 8a and 8c.

On the aluminum extruded profile 105, which on the upper plate 52 of the

Side part 1 1 of the bottom pan is fixed, an angle 100 is set, which is fastened with its horizontal leg 1 12 to a pin 104. The bolt 104 is part of the profile 105. The vertical leg 10 of the angle 100 bears against the profile 101. By fixing the leg 1 12 to the bolt, the cabin side wall 8a and the cover profile 101 are fixed in position relative to the quarter-circle end of the profile 105 which, as an aperture, obscures the gap between the plate 52 and the side wall 8a.

Between the profile 101 and the vertical leg a felt strip 103 is provided. A protruding from the profile 101 and the profile carrier parallel leg 106 has a vertical slot. In this slot is a horizontally projecting from the vertical leg 1 10 of the angle 100 pin 107 with a stuck on it elastic ring 102 introduced. The bearing of the pin 107 with the elastic ring in the vertical slot allows a resilient relative movement of the bottom pan and the upper board 52 against the cabin side walls 8a and 8c in the z direction in the region of the transition between the side walls.
