An independent claim is included for a method for manufacturing a device for cantilevered fastening a passenger seat to a wall of car body of a vehicle.

Description

The invention relates to a device for cantilever mounting a passenger seat on a wall of a vehicle and a method for producing such a device. Passenger seats are available in various vehicles, e.g. in airplanes, buses or trains, designed to provide seating for passengers, and a body of such a vehicle. The passenger seats usually consist of a seat and a rigid or pivotally connected to this backrest. Such a passenger seat can be either a single or a double or multiple seat.

A passenger seat is hereby usually mounted on a device for fastening the passenger seat, e.g. a base frame or a seat support, attached. The subframe or seat support, in turn, may be connected to a wall, e.g. a side wall to be connected to the vehicle. Also, the base or the seat support can be supported by feet on a floor surface of the vehicle. This results in an increased time required for cleaning, especially in frequently cleaned vehicles, since feet can hinder a cleaning process.

However, there are also known devices for mounting seats that are self-supporting. For example, the DE 195 26 840 A1 a subframe for cantilever mounting a passenger seat on a wall of a vehicle with a wall-mounted attachment and a substantially perpendicular to the wall Sitztragarm. The subframe is formed by at least one parallel to the wall extending extruded profile, which is provided with a substantially extending in the direction of Sitztragarmes stiffening band.

The EP 1 864 855 A1 discloses a seat support having a support portion extending along a support axis for supporting at least one seat and a connection end for mounting the seat support to side fasteners of a passenger compartment. The seat carrier includes two spaced-apart side surfaces extending from the connection end substantially to the free end of the seat carrier, wherein the extension of the side surfaces normal to the carrier axis decreases from the connection end toward the free end of the seat carrier.

Such cantilevered fastening devices are usually solid designed to accommodate the required high bending and torsional moments.

There is a technical problem to provide a device for cantilever mounting a passenger seat and a method for producing such a device and a car body of a vehicle, which make it possible to secure a passenger seat, with a weight and space requirements of the device for cantilever mounting is reduced.

The solution to the technical problem results from the objects having the features of claims 1, 13 and 16. Further advantageous embodiments of the invention emerge from the subclaims.

Proposed is a device for cantilever mounting a passenger seat on a wall, in particular a side wall of a vehicle, such as a rail vehicle. The device may in this case comprise or have a wall-side end face and a free end face. On a wall-side end side, the proposed device may comprise a fastening element or a plurality of fastening elements for fastening the device to the wall of the vehicle. Unsupported means that no further mechanical connection of the proposed device to further areas of the vehicle, for example a floor area or a ceiling area, is necessary at a free end of the device.

The device comprises at least a first support element and at least one further support element. The device may also comprise a plurality of first support elements and a plurality of further support elements. This will be explained in more detail below. The first and the further support element are connected, for example mechanically connected. Thus, at least the first and the further support element form the proposed device.

According to the invention, the first and the further support element are designed and / or mechanically connected in such a way that, by means of the first support element, predominantly or exclusively forces can be absorbed in a main direction. Next are by means of further support member mainly or exclusively absorbable forces in at least one direction, which is different from the main direction. The direction / directions different from the main direction may include, for example, an angle from an angle range of -60 ° to -30 ° and / or an angle range of 30 ° to 60 ° with the main direction.

Preferably, by means of the further support element mainly forces in a first oblique direction can be accommodated, which includes an angle from an angle range of -50 ° to -40 °, preferably an angle of -45 °, with the main direction. Alternatively or cumulatively, forces in a second oblique direction can be absorbed by means of the further support element, which includes an angle from an angle range of 40 ° to 50 °, preferably an angle + 45 °, with the main direction.

In this case, it may predominantly mean that a maximum force acting in a main loading direction, e.g. in the case of the first support member in the main direction, is receivable greater than all other maximum forces that are receivable in directions that are different from the main load direction. For example, the maximum force that is absorbable in the main loading direction may be at least 1.2 times a maximum force out of a set of all other maximum forces that are receivable in directions that are different from the main loading direction. Thus, the first material may be anisotropic with respect to a strength behavior.

The property "exclusively" does not exclude that due to material properties small forces can be absorbed in a direction that is different from the main direction.

The main direction may be a main direction of the first support element or a main direction of the proposed device. The main direction denotes a direction in which the device and in particular the first support element can absorb a maximum force, in particular a tensile or compressive force. Since the first support element and the further support element are mechanically connected, by means of the further support element in the connected state, predominantly forces can be absorbed in one direction, which is different from the main direction. The main direction may be a direction from a wall-side end of the device to a free end of the device Be device. For example, as previously explained in connection with the proposed device, the first support element and the further support element may likewise have a wall-side end and a free end, wherein the wall-side end can be fastened to a wall of the vehicle. In this case, for example, fastening elements for fastening the support element to the wall of the vehicle can be arranged on a wall-side end. The main direction may in this case be a direction from the wall-side end to the free end of the first support element. If the device according to the invention is fastened to a wall of the vehicle, then the main direction extends substantially perpendicular to the wall of the vehicle into a vehicle interior.

In a special embodiment, the fact that primarily forces can be absorbed by the first support element in the main direction is the case when the first support element is designed such that its flexural rigidity is at most transverse to or perpendicular to the main direction for a load. In particular, this load may be a load generated by a weight of a passenger seated in the passenger seat. In this case, a direction of the load from a ceiling of the vehicle to a floor of the vehicle. The maximum bending stiffness may have a predetermined value. In contrast, the further support element is designed such that its bending stiffness at this load is less than the flexural rigidity of the first support element.

In the case of a load transversely or perpendicular to the main direction, in particular under load by a weight of a passenger seated on the passenger seat, areas or layers of the first support element can be subjected to tension in the main direction and other areas or layers to pressure in the main direction. Thus, the property that the first support member can mainly absorb forces in the main direction, in this embodiment, synonymous with the previously described maximum bending stiffness.

The fact that forces which can be absorbed by the further support element predominantly differ from the main direction is the case in a special embodiment when the further support element is designed such that its torsional rigidity has a predetermined value. Also, the torsional rigidity can be at a maximum for a torsional load around the main direction. In contrast, the first one is Support member formed such that its torsional stiffness in this torsional load is less than the torsional stiffness of the other support member.

As a result, the properties of the first support element are predominantly to absorb forces in the main direction and to receive the further support element mainly forces in at least one direction different from the main direction synonymous with the fact that the flexural rigidity of the first support member is greater than that of the further support member and the torsional stiffness of the other Supporting element is greater than that of the first support element.

The device can be formed here as a profile element with a hollow profile. Also, this hollow profile may be filled with a filler, e.g. Foam, be filled. A mechanical connection of the first support element and the further support element may e.g. be a bolt connection. However, the mechanical connection is preferably an adhesive connection. Of course, other releasable or non-releasable mechanical connections, e.g. a welded joint, a screw connection or a riveted joint, conceivable.

The first support element may be made of a first material and the further support element may be formed of a further material. Here, the material properties of the first and the further material may differ at least with respect to a strength behavior of the first and the further material. The first material and / or the further material may each have anisotropic material properties with respect to a strength behavior.

In the proposed arrangement of the first support member relative to the further support member in the mechanically connected state, the material properties of the first support member are different from the material properties of the further support member, the material properties with respect to loads or forces relative to a common coordinate system of the first support member and the further supporting element are defined, are existing material properties.

If the proposed device is fastened (fastened state) to a vehicle wall, for example a side wall of a car body of the vehicle, in such a way that the longitudinal or main direction of the first support element is substantially perpendicular to the vehicle body Vehicle wall is oriented and thus the proposed device protrudes into a vehicle interior, the first support member may preferably absorb forces resulting from a bending of the device. Bending occurs, for example, due to a load generated by a seated passenger. Accordingly, by means of the further support element preferably torsional forces resulting from a torsion of the device can be absorbed. Torsional forces arise in particular when a passenger holds on an approaching vehicle to a backrest of a passenger seat. In this case, therefore, the first support element mainly or exclusively serves to accommodate bending forces and the further support element predominantly or exclusively for absorbing torsional forces which are exerted on the device. Thus, torsional forces refer to a torsion of the device about the main direction of the device.

The proposed device advantageously enables a cantilevered mounting of passenger seats to a wall of a vehicle which can accommodate the necessary bending and torsional forces, whereby a space requirement and a weight of the device can be kept low.

In a preferred embodiment, the first support element is formed from a first fiber composite material, which comprises predominantly or exclusively fibers which are oriented substantially in a main direction. Accordingly, the further support element is formed from a further fiber composite material, which comprises predominantly or exclusively fibers, which are oriented substantially at an angle of + 45 ° and / or -45 ° to the main direction. In this case, the first and the further support element can be mechanically connected in such a way that the desired fiber orientation is produced. Thus, it is also possible that the support elements consist of the same fiber composite material, wherein the support elements are mechanically connected according to the desired fiber orientation.

In this case, predominantly means that in the fiber composite material, a small proportion of fibers, for example a proportion of less than 50% of all fibers, can not be oriented in the direction indicated, for example in the case of the first support element, the main direction. Essentially in one main direction, this means that the first fiber composite material can also have fibers which are oriented at an angle from an angle range of, for example, -15 ° to 15 ° to the ideal main direction.

Substantially at an angle of -45 ° and / or + 45 °, this means that the further fiber composite material may also comprise fibers which are at an angle from an angular range of e.g. -60 to -30 ° and / or are oriented from an angle range of 40 ° to 50 ° to the ideal main direction.

A fiber composite material may in this case be, for example, a glass fiber, carbon fiber or another fiber composite material. The reinforcing fibers may have a variety of shapes, e.g. be designed as short or long single fibers or as woven, braided or sewn semi-finished fiber. The proposed fiber composites preferably have the previously explained anisotropic material properties with respect to a strength behavior. For this purpose, fibers of the fiber composite material may for example be arranged such that they are oriented predominantly or exclusively in one direction, in which direction tensile forces can be absorbed.

The first support element and the further support element are in this case mechanically connected to one another such that the first fiber composite material can absorb forces in particular in the main direction and the further fiber composite material forces in at least one direction different from the main direction. The further fiber composite material may preferably absorb torsional forces. In this case, the device forms a sandwich-composite construction which comprises supporting elements, in particular support elements formed as support layers, of fiber composite materials with different fiber orientation. As a result, anisotropic behavior with respect to a strength behavior of the entire device can be achieved.

This results in an advantageous manner that the device according to the invention can be easily manufactured, with anisotropic properties of the fiber composites are specifically exploited. Since fiber composites generally have a low weight, there is also a reduced total weight of the proposed device.

In a further embodiment, the first support element and the further support element are formed as separate components. These can then, like previously explained, for example by means of an adhesive method, mechanically connected. Due to the design as separate components results in an advantageous manner that a production of the first and the other support element process technology can be separated from each other.

In a further embodiment, the first support element and the further support element are integrally formed. For example, the device according to the invention may comprise a plurality of layers, which are formed from mutually different materials, namely the first and the further material. For example, e.g. it is conceivable that a fiber composite material is produced by orienting fibers in at least one first layer essentially in the main direction explained above, with fibers being oriented in at least one further layer at an angle of + 45 ° and / or -45 ° to this main direction , The first and second layers can also follow each other individually or in several layers alternately. Only then is a potting and thus a bonding of the fibers. Thus, the device is formed as a one-piece device, wherein the first and the further support element are integral parts of this device.

This results in an advantageous manner a durable and very robust mechanical connection of the first and the further support member.

In a further embodiment, the device comprises a first support profile and a further support profile. The first support profile and the further support profile are, e.g. in a connection area, connected. The first support profile comprises a first profile element and a further profile element. The first profile element is connected to the further profile element of the first support profile.

Accordingly, the further support profile comprises a first profile element and a further profile element, wherein the first profile element and the further profile element of the further support profile are connected. The first profile elements form the previously explained at least one first support element of the proposed device. Accordingly, the further profile elements form the at least one further support element of the proposed device.

The profile elements of the first support profile and the profile elements of the further support profile as well as the first support profile and the further support profile are in this case formed and / or mechanically connected to each other, that by means of the first profile elements mainly forces in the main direction can be accommodated, wherein by means of the other profile elements predominantly forces in a direction different from the main direction can be accommodated. The first profile element of the first support profile and the first profile element of the further support profile can be formed, for example, from the first material, in particular the first fiber composite material. The first profile elements thus serve to absorb forces in the main direction. Accordingly, the further profile element of the first support profile and the further profile element of the further support profile of the further material, in particular the further fiber composite material formed. These further profile elements thus serve to absorb forces which are oriented at an angle of from an angle range of -50 ° to -40 °, preferably -45 °, and / or from 40 ° to 50 °, preferably + 45 °, to the main direction are.

Here, the first support profile and the further support profile can be designed and / or mechanically connected such that the resulting device has a hollow profile in a cross section to the main direction. This results in an advantageous manner, a particularly lightweight device for cantilever mounting a passenger seat, while male bending and torsional forces can be maximized.

Here, e.g. the first profile element of the first support profile may be mechanically connected in a connection region with the first profile element of the further support profile.

The first profile elements consist of a fiber composite material which comprises predominantly or exclusively fibers which are oriented essentially in the main direction of the first support element, and the further support element is formed from a further fiber composite material which comprises predominantly or exclusively fibers which are substantially in one Angle of + 45 ° and / or -45 ° to the main direction is oriented, so the first profile element and the further profile element of the first support profile and / or the other support profile, as previously explained with respect to the support members, integrally formed by the manufacturing process different fiber layers with differently oriented fibers placed on each other and then shed.

The formation of the device by two support profiles results in an advantageous manner a simple production of the device according to the invention.

In a further embodiment, the first support profile and the further support profile are integrally formed. An integral embodiment can, as explained above with reference to the support elements, be understood as an integral construction of the support profiles. Alternatively, the first support profile and the further support profile may be formed as separate components. In this case, the support profiles may be connected in a connection area. In this case, the first support profile and the further support profile, e.g. be connected via an adhesive connection, a bolt connection, a screw connection, a rivet connection or another releasable or non-detachable mechanical connection.

In a further embodiment, the first profile element and the further profile element of the first support profile are formed integrally or as separate components. Alternatively or cumulatively, the first profile element and the further profile element of the further support profile are formed integrally or as separate components.

Under an integral training can, as previously explained with reference to the support elements, an integral formation of the profile elements of a support profile are understood. Thus, the first profile element and the further profile element of the respective support profile can be integral elements of the support profile. This will be explained in more detail below.

Alternatively, the first profile element and the further profile element of the respective support profile may be formed as separate components. The profile elements of the first support profile or the profile elements of the further support profile can be mechanically connected to each other in this case. Thus, the first profile element and the further profile element can be connected to one of the previously explained releasable or non-detachable mechanical connection.

In a further embodiment, the further profile element of the first support profile has a substantially U-shaped cross section. Alternatively or cumulatively, the further profile element of the further support profile has a substantially U-shaped cross section. The cross section here refers to a cross section perpendicular to the main direction of the first support element, which may be equal to a main direction of the other profile elements. Here, the U-shaped cross-section on a base leg and two side legs, wherein the side legs each with the base leg an angle from an angular range of e.g. + 30 ° to + 100 °. In a fixed state of the device, a part of the further profile element forming the base leg can be arranged substantially perpendicular to a vehicle side wall and substantially parallel to a bottom surface of the vehicle. On one, e.g. towards a ceiling of the vehicle oriented surface of the base leg forming part passenger seats can be mounted here.

The formation of the further profile elements with a substantially U-shaped cross-section advantageously allows a simple process engineering production of the other profile elements, which are nevertheless suitable for a desired recording of bending and torsional moments resulting from loads.

In a further embodiment, a length of one side leg of the further profile element of the first support profile and / or of the further profile element of the further support profile along the main direction, e.g. towards a free end of the device. Thus, a length or height of a side leg decreases toward the free end of the device. In other words. In a fixed state of the device, a length or height of a side leg of a further profile element at a wall-side end of the support profile maximally and at a free end of the support profile may be minimal. This results in a particularly advantageous manner, a material and space-saving design of the proposed device, which can still accommodate desired bending and torsional forces. Also results in an advantageous manner by the decreasing length or height of the side legs, that a cleaning of the vehicle, especially under the seats, is simplified.

In a further embodiment, the first profile element of the first support profile and / or the first profile element of the further support profile is designed as a support plate. This support plate may have a rectangular or trapezoidal cross section, wherein The cross-section along the main direction can be constant, so it can have a constant width and height. In this case, the first profile element of the first support profile can be encompassed or enclosed by the further profile element of the first support profile. For example, the first profile element embodied as a support plate can be arranged in a volume enclosed by the base leg and the side legs of the further profile element. Corresponding statements apply with respect to the profile elements of the further support profile. This results in an advantageous manner, a particularly simple production of the other profile elements.

In a further embodiment, the first support profile and the further support profile are mechanically connected to one another such that the U-shaped cross sections of the further profile element of the first support profile and of the further profile element of the further support profile are opened to a same side. For example, the further support profile can be arranged within the first support profile. For example, the further support profile may be arranged at least partially in a volume encompassed by the base leg and the side legs of the first profile element of the first support profile. In this case, therefore, the further support profile can be inserted into the first support profile, which allows a particularly simple production of the proposed device. Here, the first support profile and the further support profile form a closed housing with a cavity.

In an alternative embodiment, the first support profile and the further support profile are connected to one another in such a way that the U-shaped cross sections of the further profile elements of the first support profile and of the further support profile are open to one another. Here, the first support profile and the further support profile can also form a closed housing with a cavity. Thus, a circumference of a hollow profile of this closed housing can be advantageously increased, which can lead to an improved absorption of bending and torsional forces.

Furthermore, one side limb of the further profile element of the first support profile and one side limb of the further profile element of the further support profile can each have a connection surface via which the first support profile is mechanically connected to the further support profile. The connection surfaces can in this case rest against one another and be connected, for example, by one of the previously explained detachable or non-detachable mechanical connections.

Further proposed is a car body of a vehicle, in particular a rail vehicle. However, the vehicle may also be a non-rail vehicle, such as a bus. The vehicle body has at least one side wall and comprises at least one of the previously described devices for the cantilever mounting of a passenger seat. The device is attached to the side wall, e.g. by means of appropriate fasteners. The device comprises at least a first support element and at least one further support element, wherein the first and the further support element are mechanically connected. The first support element and the further support element are mechanically connected such that predominantly forces can be absorbed in a main direction of the first support element by means of the first support element, wherein by means of the further support element predominantly forces can be absorbed in at least one direction, which is different from the main direction. The main direction here is a direction that is oriented substantially perpendicular to the side wall of the rail vehicle.

Further proposed is a method for producing a device for the self-supporting attachment of a passenger seat to a wall of a vehicle. In this case, at least one first support element and at least one further support element is provided. The first and the further support element are in this case formed and / or connected to one another that by means of the first support element predominantly forces in a main direction are receivable and by means of the further support element predominantly forces in at least one direction can be accommodated, which is different from the main direction. This results in an advantageous manner a simple production of a device for cantilever mounting, which has a reduced weight and a reduced space requirement.

In a further embodiment, the first support element is made of a first fiber composite material, which comprises predominantly or exclusively fibers, which are oriented substantially in the main direction. Furthermore, the at least one further support element is made of a further fiber composite material which, especially in a mechanically connected state, comprises predominantly or exclusively fibers which are essentially at an angle of + 45 ° and / or -45 ° to the main direction of the above-mentioned having first support element.

As a result, advantageously anisotropic properties of fiber composite materials can be used in the production of a proposed device.

In a further embodiment, a first support profile is provided, wherein the first support profile comprises a first profile element, e.g. from the first material, in particular from the first fiber composite material, and another profile element, e.g. from the further material, in particular the further fiber composite material, wherein the first profile element with the further profile element of the first support profile, e.g. mechanically, is connected. Accordingly, at least one further support profile is provided, wherein the further support profile comprises a first profile element, e.g. from the first material, in particular the first fiber composite material, and another profile element, e.g. from the further material, in particular the further fiber composite material, wherein the first profile element and the further profile element of the further support profile, e.g. mechanically, be connected. Furthermore, the first support profile and the further support profile are connected to one another such that the first profile elements form the first support element and the further profile elements form the further support element.

This results in an advantageous manner a simple production of the proposed device.

Also proposed is a method for producing a car body of a vehicle, in particular a rail vehicle, wherein one of the above-explained devices for cantilever mounting a passenger seat is secured to a side wall of the car body, that the above-explained main direction is oriented substantially perpendicular to the side wall.

Hereinafter, like reference numerals designate elements having the same or similar technical characteristics.

In Fig. 1 is a side view of a first embodiment of a device 1 according to the invention shown. The device 1 is used for self-supporting attachment of passenger seats 2 on a side wall 3 of a car body of a vehicle, such as a rail vehicle. Here it is shown that the device 1 projects beyond a bottom surface 4 of the vehicle in an interior of the vehicle. The device 1 comprises a first support profile 10 and a second support profile 20. The first support profile 10 comprises a first profile element 11 (see eg Fig. 2 ) and another profile element 12. Accordingly, the further support profile 20 comprises a first profile element 21 (see, for example Fig. 2 ) and another profile element 22. The device 1 further comprises a mounting plate 5, by means of which the device 1 is attached to the side wall 3. Here, the device 1 in Fig. 1 shown in a fastened state.

Next, a main direction of the device 1 is shown by an arrow 6. The main direction (arrow 6) is oriented perpendicular to the side wall 3 in the fastened state of the device 1, wherein the main direction (arrow 6) is oriented parallel to the bottom surface 4. The main direction (arrow 6) of the device 1 is in this case at the same time a main direction of the other profile elements 12, 22. The main direction (arrow 6) is from a wall-side end of the device 1, on which the mounting plate 5 is arranged, towards a free end the device 1 directed, which projects into a vehicle interior.

Further, a first oblique direction is represented by an arrow 7, which encloses an angle of + 45 ° with the main direction (arrow 6). Analogously, a second oblique direction is represented by an arrow 8, which encloses an angle of -45 ° with the main direction (arrow 6). In Fig. 1 is shown that the oblique directions (arrows 7, 8) at an angle of + 45 ° and -45 ° with the main direction (arrow 6) include in planes that are approximately perpendicular to the bottom surface 4 and the side wall 3. Such a level can for example, by a surface of a side leg 14, 24 (see also Fig. 2 ) of the further profile elements 12, 22 are formed.

Such a plane can be formed, for example, by a surface of base legs 13, 23 of the further profile elements 12, 22.

In Fig. 2 is a cross section through the device 1 according to the invention, which in Fig. 1 is shown, wherein a cross-sectional plane perpendicular to in Fig. 1 illustrated main direction (arrow 6) runs. In Fig. 2 it is shown that the further profile element 12 of the first support section 10 has a U-shaped cross section. Here, the further profile element 12 has a base leg 13 and side legs 14, wherein in Fig. 2 only one side leg 14 is shown. Further, the first support section 10 comprises a first profile element 11, which is designed as a support plate which covers the base leg 13 at least partially. The first profile element 11 and the further profile element 12 of the first support profile 10 are in this case mechanically connected to one another in the region of the base leg 13. It is shown here that the first profile element 11 is arranged within the volume of the further profile element 12 encompassed by the base leg 13 and the side legs 14.

Also shown is the second support profile 20, which also has a first profile element 21 and a further profile element 22. Here, the further profile element 22 of the second support profile 20 also has a substantially U-shaped cross-section. In Fig. 2 It is shown that the further profile element 22 of the second support section 20 in the region of side legs 24 has an offset 25 or forms. This offset 25 forms a stop for side legs 14 of the further profile element 12 of the first support section 10, when the first support section 10 and the second support section 20 as further explained below are inserted into each other to form the device 1. According to the first support profile 10, the further profile element 22 of the second support profile 20 comprises a base leg 23 and side legs 24. A first profile element 21 is also formed as a support plate which covers the base leg 23 at least partially, and within one of the base leg 23 and side legs 24 included Volume of the other profile element 22 of the second support section 20th arranged and mechanically connected thereto. It is further shown that the further profile elements 12, 22 in the region of side legs 14, 24 each form a connecting surface 16, 26. Here, the first support section 10 and the second support section 20 in the region of these connection surfaces 16, 26 are mechanically connected to each other.

Within the profile elements 11, 21 extend in the main direction (arrow 6, see, eg Fig. 1 ) arranged in layers parallel to the bottom surface. Within the profile elements 12, 22 arranged at an angle of + 45 ° and -45 ° to the main direction (arrow 6) arranged fibers in layers that follow the course of the U-shape.

It is further shown that the U-shaped cross-sections of the further profile elements 12, 22 towards a same side, namely toward a bottom surface 4 (see Fig. 1 ), are open. The device 1 resulting from the mechanical connection of the first support profile 10 and the second support profile 20 has a hollow profile with a cavity 9.

In Fig. 1 It is shown that a height or length L of side legs 14, 24 along the main direction (arrow 6), ie from a wall-side end towards a free end of the device 1, decreases.

Referring to Fig. 3 Now, a structure of the profile elements 11, 12, 21, 22 of the first support section 10 and the second support section 20 will be explained.
