Description

[0001] This application is a divisional application of the invention patent application filed on September 16, 2020, with application number 202010973591.6 and invention title "Seat device for transportation vehicle". Technical Field

[0002] The present invention relates to a seating device for a means of transport, particularly for a passenger transport, wherein the seating device is arranged on the means of transport by means of fastening. Background Technology

[0003] Such transportation vehicles are provided, and these vehicles are suitable for carrying multiple people, and are, for example, rail vehicles or airplanes. Corresponding rail vehicles include, for example, local and / or long-distance trains, suburban trains, subways, etc. It is necessary to optimize the use of available space in such transportation vehicles as much as possible. A transportation vehicle should be able to accommodate as many passengers as possible. By setting up conventional seating arrangements, where users sit in a conventional sitting posture with their legs bent, users occupy a relatively large space in the transportation vehicle. In contrast, by providing standing positions, a considerable number of people can be accommodated in the transportation vehicle. However, standing positions usually also mean an unacceptable loss of travel comfort, especially on longer journeys. Another disadvantage of previous seating arrangements is that they cannot be modified according to the user's needs. For example, the direction of the seats cannot be changed. Orientation adjustments, such as adjustments towards the direction of travel of the transportation vehicle, are generally not possible. Similarly, seating groups are usually set up, where two pairs of seats face each other, or where pairs of seats are arranged in rows. Therefore, it is impossible to accommodate the needs of small travel groups or families using such seating groups. Summary of the Invention

[0004] The object of this invention is to provide a seating device that overcomes the aforementioned disadvantages. Furthermore, the object of this invention is to provide an internal device for a transportation vehicle that overcomes the aforementioned disadvantages.

[0005] A key aspect of the invention is to provide a seating arrangement for a transport vehicle, particularly a passenger transport vehicle, wherein the seating arrangement can be mounted on or within the transport vehicle by means of a fastening device. The seating arrangement is configured and adapted to provide a seated position at a standing height, and includes at least one frame element arranged on the fastening device via at least one mounting shaft, wherein the at least one mounting shaft is received in at least one receiving device of the fastening device, wherein the at least one receiving device is arranged on the fastening element, which is configured as an arm element extending along a height axis (Z).

[0006] In the following text, a coordinate system with a height axis (Z), a width axis (Y), and a depth axis (X) is used for the seating assembly. A coordinate system with a height axis (Z'), a width axis (Y'), and a depth axis (X') is used for at least one frame element. Each axis may also have two directions.

[0007] The frame element preferably includes an upper region and at least one seat region, the upper region for supporting the back, the at least one seat region being integrated into the at least one frame element. Thus, the at least one frame element functions as a backrest and also as a seat portion. Therefore, a very simple and inexpensive seating arrangement is provided. The first and second seat regions of the at least one frame element preferably have an extension between 10 cm and 50 cm, more preferably between 15 cm and 40 cm, along the depth axis (X'). Due to the construction with a seat region integrated into at least one frame element, the seating arrangement already has a smaller range in the depth direction than conventional seating arrangements or vehicles. Since at least one frame element already includes an integrated seat region, no additional seat components are needed or required. Furthermore, the seat region is arranged at a height that allows sitting or leaning at standing height. This seating arrangement is also called a sit-stand seat. Due to the advantageous construction of the sit-stand seat, the occupant of the seating arrangement does not adopt a conventional sitting posture. Instead, the occupant adopts a sitting posture in the seating arrangement that approximately corresponds to a standing posture. This sitting posture requires less space than the conventional sitting posture, in which the legs are bent at approximately a right angle. Therefore, the depth of the advantageous seating arrangement is much less than that of a conventional seat. This provides passengers in the transportation vehicle with a very simple yet comfortable sitting / standing option. Compared to standing, the pressure on the legs and blood circulation is reduced when sitting upright. This promotes healthy "dynamic sitting." Thus, seating options are provided to as many travelers as possible, thereby offering acceptable travel comfort. Furthermore, the available space in the transportation vehicle is optimized as much as possible. Seating areas are advantageously arranged at a height between 40cm and 150cm, preferably between 40cm and 130cm. The seat height is advantageously matched to the intended target population. Seating arrangements intended for children or the elderly preferably have a seat height in the range of 40cm to 60cm. Seating arrangements for adults should have a height in the range of 80cm to 150cm, more preferably between 80cm and 130cm.

[0008] According to a preferred embodiment, at least one frame element is formed by a lower part and an upper part. The at least one frame element preferably has a base region extending along a height axis (Z') and a width axis (Y'). The base region is preferably designed as a polygon. The base region is preferably designed as a square. The base region is preferably substantially designed as a rectangle or substantially designed as a trapezoid. The term "substantially" as used should be interpreted to include small tolerances in shape with respect to length or angle. Thus, the deviation can be an angle preferably less than 10°, more preferably less than 7.5°, and even more preferably less than 5°. This also applies to the term "substantially" as used below. According to another preferred embodiment, the lower and upper parts of at least one frame element are integrally formed, in one or more pieces, particularly two pieces, of at least one frame element. In the case of a one-piece design, the frame element, or the upper and lower parts, are manufactured as a single and unified part, or as a so-called integral unit. The various parts are advantageously made of the same material. One-piece design should be understood in this article as a design where, although not all parts are made up of single and isolated components, they are not only firmly connected but also so closely intertwined that they do not appear as multiple connected components and cannot be separated from each other without being destroyed.

[0009] Advantageously, the lower portion includes at least one first transverse portion extending substantially along the width axis (Y') and a second transverse portion extending substantially along the width axis (Y'). The upper portion preferably includes a third transverse portion extending along the width axis (Y'). The first and second transverse portions preferably have an extension along the depth axis (X'). This extension is advantageously increased compared to the extension of the third transverse portion along the depth axis. Preferably, the first and / or second transverse portions at least partially form the seating area. Preferably, the first and second transverse portions extend in opposite directions along the depth axis. The first and second transverse portions are preferably connected to each other. The first and second transverse portions are preferably formed integrally or in one piece. The first and second transverse portions are advantageously spaced apart from the third transverse portion along the height axis (Z') and connected by means of two support elements. Preferably, the first and second transverse portions extend more along the depth axis (X') than the third transverse portion. Advantageously, the lower and upper portions surround the inner surface. Similarly, the first and second transverse portions surround the two support elements and, together with the third transverse portion, surround the inner surface. Therefore, at least one frame element is substantially plate-shaped, in which case, at the lower end along the height axis, first and second lateral portions with enlarged depth extensions are provided, resulting in the seat area being at least partially formed.

[0010] According to another advantageous embodiment, at least one frame element can pivot relative to the fastening device about a pivot axis extending along the width axis (Y', Y). Thus, at least one frame element can pivot integrally relative to the pivot axis. As a result, both the advantageous upper region for supporting the backrest and the advantageous integrated seat region pivot or rotate simultaneously about the pivot axis. In contrast, in conventional seating arrangements, only the backrest can pivot about the pivot axis. According to another preferred embodiment, at least one frame element can pivot to at least two pivot positions. At least one frame element is preferably pivotable to three pivot positions. At least one frame element is preferably pivotable to a first pivot position. In the first pivot position, the frame element preferably extends substantially perpendicular to a first imaginary plane that extends parallel to the floor of the vehicle. Advantageously, at least one frame element can pivot to a second pivot position that is inclined at an angle (α) relative to the first pivot position. At least one frame element is preferably pivotable to a third pivot position that is inclined at an angle (β) relative to the first pivot position. Advantageously, a second imaginary plane can be defined, which is perpendicular to the first imaginary plane. At least one frame element in the first pivot position is advantageously arranged substantially in the second imaginary plane. In the second and third pivot positions, at least one frame element preferably includes an angle of inclination α or β with respect to the second imaginary plane. Advantageously, at least one frame element is inclined in opposite directions along the depth axis (X) in the second and third pivot positions. The angles of inclination (α) and (β) are therefore advantageously of different signs (±). However, the angles of inclination (α) and (β) preferably have the same amount. The angles of inclination (α, β) are preferably in the range of 10° to 80°, more preferably in the range of 20° to 70°, in which case at least one frame element and the second imaginary plane include this angle of inclination (α, β).

[0011] At least one mounting shaft allows at least one frame element to pivot or rotate about a pivot axis. This pivot axis preferably extends through or along the mounting shaft. According to another preferred embodiment, only one mounting shaft is provided, which is received in at least one receiving device of the fastening device. The mounting shaft is preferably received in two receiving devices of the fastening device, which are spaced apart from each other along width axes (Y, Y′). Advantageously, at least one frame element is arranged between the two receiving devices of the fastening device. According to another preferred embodiment, a through channel for the mounting shaft is provided at the lower end of at least one frame element along a height axis (Z'). The mounting shaft advantageously extends through the through channel of at least one frame element. The through channel is preferably located in the lower portion of at least one frame element. The through channel may preferably extend over the entire width of at least one frame element. The through channel preferably extends along the width direction of at least one frame element in a substantial portion. This substantial portion preferably corresponds to at least half, more preferably at least three-quarters, of the total width of at least one frame element. However, it is also conceivable that the through channel may be discontinuously closed. Furthermore, it is conceivable that the through channel has at least one, preferably two, mounting areas formed by or arranged on at least one frame element. In the remainder of the passage, the mounting shaft may preferably be exposed.

[0012] According to another preferred embodiment, the mounting shaft is non-rotatably or mechanically and rigidly connected to the fastening device or at least one receiving device connected to the fastening device. Advantageously, at least one frame element is pivotable or rotatable relative to and on the mounting shaft. It is also conceivable that the mounting shaft is connected to at least one frame element in a rotationally fixed or mechanically rigid manner. Advantageously, the mounting shaft is rotatably mounted in at least one, preferably two, receiving devices. At least one frame element and the mounting shaft pivot relative to at least one, preferably two, receiving devices or preferably rotate therefrom. It is also conceivable to provide two mounting shafts arranged along a width axis (Y, Y′) on the lower portion of corresponding opposite sides of at least one frame element such that they protrude along the width axis (Y, Y′) above at least one frame element. The two mounting shafts are then rotatably mounted in corresponding receiving devices of the fastening device.

[0013] According to another preferred embodiment, a latching device is provided by means of which at least one frame element can be locked in at least one pivot position. At least one frame element can preferably be locked in at least two or at least three pivot positions by means of the latching device. Advantageously, at least one frame element can be locked in all intended pivot positions by means of the latching device. If at least one frame element pivots to a first pivot position and is preferably locked in that pivot position, it is upright aligned and substantially arranged in a second imaginary plane perpendicular to the first imaginary plane. In this position, the seat assembly is not occupied by a user. The effective depth of the seat assembly in this position substantially corresponds to the sum of the depth extensions of the first and second lateral portions of the at least one frame element. Therefore, the seat assembly occupies minimal space along the depth axis in the first pivot position. The fact that at least one frame element occupies very little space when its upright extension extends makes it possible, for example, to efficiently mount the seat assembly. Furthermore, in the case of multiple seat assemblies arranged in a row, the intermediate space can be expanded by pivoting to the first pivot position. According to another advantageous embodiment, in the second pivot position of at least one frame element, the first seat area is formed by at least the first lateral portion. In the third pivot position of at least one frame element, the second seat area is preferably formed by at least the second lateral portion. At least one frame element can advantageously pivot to the first pivot position, to the second pivot position, and to the third pivot position, and can advantageously lock in these pivot positions. Because the first and second lateral portions preferably extend in opposite directions along the depth axis (X), and because the tilt angles (α, β) of at least one frame element are opposite in the second and third pivot positions, the first and second seat areas are arranged in opposite directions along the depth axis (X). This configuration allows the seat alignment to be easily adapted to the direction of travel. For some vehicles, such as rail vehicles, changes in direction may occur during travel. For example, this can happen when entering or leaving a terminal station. However, some users are uncomfortable when traveling in the opposite direction. By simply pivoting, for example, from the second pivot position to the third pivot position, the orientation of the seat assembly can be easily adapted to the direction of travel.

[0014] According to another preferred embodiment, at least one frame element can advantageously pivot to a first pivot position and a second pivot position, and can advantageously be locked in these pivot positions. Another conceivable embodiment is that at least one frame element can pivot to a first pivot position and a third pivot position, and can advantageously be locked in these pivot positions. Thus, according to these embodiments, the seating arrangement will continue to be configured to be in an upright pivot position only in one seating direction. According to another preferred embodiment, at least one frame element can advantageously pivot to a second pivot position and a third pivot position, and can advantageously be locked in these pivot positions. According to this embodiment, the seating arrangement will be designed for two opposite seating directions. However, no upright pivot position for installation will be provided. Ultimately, it is conceivable that at least one frame element can only be in the second or third pivot position, and is locked or fixed in that pivot position. Of course, it is also conceivable that at least one frame element can pivot to another pivot position and can be locked in these pivot positions. Such another pivot position may be located between the first and second pivot positions, or may be located between the first and third pivot positions. The corresponding tilt angle will be smaller than the aforementioned tilt angle (α, β). This will allow the occupant to adjust the upper tilt to support their back as needed. According to another advantageous embodiment, in a second pivot position of at least one frame element, the first seat area extends substantially parallel to or horizontally to a first imaginary plane. In a third pivot position of at least one frame element, the second seat area preferably extends substantially parallel to or horizontally to the first imaginary plane. The first lateral portion preferably includes an upper surface that extends substantially parallel to the first imaginary plane in the second pivot position. The second lateral portion advantageously includes an upper surface that extends substantially parallel to the first imaginary plane in the third pivot position.

[0015] According to another preferred embodiment, at least one gripping element is provided on at least one frame element. Preferably, the at least one gripping element is arranged along the height axis (Z) on one of the support elements in the upper region. Thus, the gripping element is arranged entirely or at least partially on the upper part of at least one frame element. The seating arrangement advantageously has a first outer side and a second outer side. Advantageously, the gripping element is arranged on one outer side, and when installed in the transport vehicle, the gripping element is located on the aisle. Thus, the gripping element forms a holding option for standing or walking passengers. It is conceivable that only the first outer side is located on the aisle of the transport vehicle. In this case, it is advantageous that the gripping element is arranged on the first outer side of the seating arrangement. However, it is conceivable that the gripping element is arranged on both the first and second outer sides of the seating arrangement. For example, it would be advantageous if there were two aisles in the transport vehicle. However, the arrangement of the gripping element is not limited to the arrangement relative to the aisle. Such a gripping element can also have other functions, such as support when standing, etc.

[0016] According to another preferred embodiment, the seating assembly comprises only one frame element arranged on the fastening device. Advantageously, the frame element is arranged between two receiving devices of the fastening device. Each receiving device is preferably arranged on the fastening element, which is adapted and configured for attaching the receiving device to the transport vehicle. The fastening element advantageously includes an arm element that extends along the height axis (Z) and leads to the base element. The corresponding arm element and receiving device are advantageously designed integrally or as a single piece. It is also advantageous that the arm element and the base element are designed integrally or as a single piece. The base element is preferably arranged below the frame element and centrally located along the height axis. The arm element is designed to converge downward along the height axis (Z). The arm element and the base element are preferably designed with a flat profile. The arm element is preferably substantially designed in a V-shape. Thus, forces can be advantageously introduced symmetrically into the base element. With this configuration, the seating assembly can be designed to be very simple. The fastening element directly engages with the mounting shaft of the frame element. Therefore, no additional components are required for mounting the frame element. The base element can advantageously be directly fixed to the floor of the transport vehicle. It is also conceivable that the fastening device or base element can be displaceably arranged on the floor of the transport vehicle by means of a guiding system. According to another embodiment, the base element includes a foot pedal element designed as a connecting element between arm elements extending along the width axis (Y) and spaced apart from the base element along the height axis. It is also conceivable that a rotating device is provided in or on the base element, by which the seating assembly can be rotated about a rotation axis extending parallel to the height axis (Z).

[0017] According to another preferred embodiment, the seat assembly includes two frame elements arranged on a fastening device. Preferably, the two frame elements are arranged adjacent to each other along a width axis (Y). The two frame elements may have the same or different designs. Each of the two frame elements may independently have the features according to the embodiments described herein. As already described, a first outer side and a second outer side of the seat assembly may preferably be defined. If the seat assembly includes two frame elements, one outer side of the seat assembly is represented by one of the two frame elements. At least one gripping element, as already described, may be arranged on one of the two outer sides. In the installed state, the outer side with the gripping element is advantageously located on the aisle of the transport vehicle. Of course, it is also conceivable to arrange at least one gripping element on both outer sides of the frame elements, thereby on both frame elements. For example, this is advantageous if the two outer sides point towards the aisle of the transport vehicle in the installed state. Of course, it is also conceivable to arrange at least one gripping element on both inner sides of the frame elements. In addition to the gripping elements on the outer sides, these are preferably provided.

[0018] Advantageously, the two frame elements can pivot independently of each other relative to the fastening device about a common pivot axis extending along the width axis (Y). As already described, the two frame elements can preferably pivot independently of each other to first, second, and third pivot positions via tilt angles (α, β). According to another advantageous embodiment, only one mounting shaft is provided. The mounting shaft advantageously extends at least over the entire width of the two frame elements. As already described, the mounting shaft extends through a through-channel between the two frame elements. Preferably, the mounting shaft is received in at least two, preferably exactly two, receiving devices of the fastening device. Each receiving device is preferably arranged on the fastening element. Preferably, at least one fastening element includes an arm element extending along the height axis (Z).

[0019] According to another preferred embodiment, a first receiving device is arranged between two frame elements. Preferably, a second receiving device is arranged on the side of one of the two frame elements, or on one of the two outer sides of the seating assembly. According to an advantageous embodiment, the first receiving device is arranged on a fastening element comprising an arm element extending along a height axis (Z). The second receiving device is preferably arranged on a fastening element, which can be arranged on the transport vehicle via a plate-like element.

[0020] The receiving device can be arranged on the wall element of the transport vehicle via a plate-like element. The plate-like element is thus arranged in a fastening plane extending substantially parallel to the second imaginary plane. The wall element of the transport vehicle advantageously includes the fastening plane. This wall element is preferably a side wall of the transport vehicle. The arm element can be designed as an extendable arm or cantilever. The arm element preferably leads to a second plate-like element, which is also arranged in the fastening plane. The arm element thus extends from the fastening plane toward the first receiving device. The arm element preferably extends obliquely upward along the height axis (Z) from the fastening plane and leads to the first receiving device. According to another advantageous embodiment, instead of the first and second plate-like elements described above, only one plate-like element extending along the fastening plane is provided. The arm element or cantilever preferably extends from this plate-like element to the first receiving device. The second receiving device is preferably arranged on the fastening element. In other words, the first and second plate-like elements described above are formed as an integral plate-like element.

[0021] According to another embodiment, a first receiving device and a second receiving device are respectively arranged on a fastening element, which includes an arm element extending along a height axis (Z). Thus, the fastening device comprises two arm elements. The first receiving device, arranged between two frame elements, is advantageously arranged on the first arm element. The second receiving device is preferably arranged on the second arm element. The second receiving device and the second arm element are advantageously arranged on the outer side of the seat assembly. At least one gripping element is also advantageously arranged on this outer side. By arranging the second receiving device and the second arm element on the same outer side as the at least one gripping element, forces that can be introduced into the seat assembly can be effectively discharged through the second arm element. Therefore, the seat assembly has advantageously increased stability on the outer side of the seat assembly. Both arm elements can be advantageously fixed to the transport floor. It is also conceivable that the arm elements are fixed to a track assembly. With this configuration, the position of the seat assembly in the transport vehicle can be changed. The two arm elements are tilted relative to a reference axis perpendicular to a first imaginary plane at an angle γ. The tilt angle γ is in the range of 5° to 20°, preferably in the range of 10° to 15°. According to another advantageous embodiment, the first and / or second arm elements include a foot pedal element. The foot pedal element is preferably oriented parallel to a first imaginary plane.

[0022] According to another preferred embodiment, a first receiving device and a second receiving device are respectively arranged on the outer side of the seat assembly. Two frame elements are preferably arranged between the first and second receiving devices. Preferably, the first and second receiving devices are respectively arranged on a fastening element comprising arm elements, wherein two arm elements extend along a height axis (Z) and lead to a base element. Preferably, the base element is arranged centrally and below the two frame elements along the height axis (Z). The arm elements are designed to converge downwards along the height axis (Z). The arm elements are preferably substantially designed in a V-shape. This embodiment can advantageously have the same other constructions and advantages as embodiments with only one frame element.

[0023] In the above-described embodiment, it is advantageous that each fastening element, each receiving device, and possibly the base element are designed integrally or as a single unit. Sufficient stability of the seating assembly is provided by mounting the two receiving devices via a continuous mounting shaft. Therefore, no additional third mounting point is required. This provides a seating assembly that saves a significant amount of material.

[0024] According to a preferred embodiment, at least one frame element is made of a metal alloy, preferably aluminum alloy. The fastening device may also be at least partially made of a metal alloy, preferably aluminum alloy. This allows the seating assembly to be constructed as lightweight as possible.

[0025] According to another particularly preferred embodiment, the seat cover is arranged on or within at least one frame element. The at least one frame element preferably includes an inner surface. Therefore, the seat cover is advantageously arranged within this inner surface. Alternatively, it is preferred that the seat cover is arranged on or above the inner surface. It is also conceivable that the seat cover at least partially surrounds the inner surface. The seat cover is advantageously positioned and designed to withstand forces introduced by the user. Therefore, the seat cover advantageously possesses corresponding stability. Therefore, no other support elements are advantageously arranged within the inner surface. The seat cover is preferably a knitted fabric. The seat cover is preferably a tubular knitted fabric or a flat knitted fabric.

[0026] The potential objective is also achieved through the interior equipment of a transport vehicle, particularly a passenger transport vehicle, which includes at least one seating arrangement according to any of the foregoing embodiments. Within the scope of the seating arrangement, the interior equipment can be equipped with all the features already described above, individually or in combination with each other, or vice versa. The interior equipment preferably includes multiple seating arrangements. According to a preferred embodiment, at least one seating arrangement is arranged on the transport vehicle to facilitate fixing or displacement by means of a guiding device, particularly a rail device. The guiding device can be arranged on the floor or wall elements of the transport vehicle. Therefore, the seating arrangement can be advantageously accommodated in the loading area of ​​the transport vehicle, such as a rail vehicle. Thus, the space of the transport vehicle can be filled with large items of luggage, such as bicycles. Depending on demand, a specific number of seating arrangements can be transported from the loading area to the interior and can be correspondingly confined to specific locations. This can be accomplished by means of corresponding advantageous latching devices.

[0027] Finally, a means of transport, particularly a passenger transport vehicle, such as a rail vehicle, is provided, having at least one interior device or at least one seating arrangement. Attached Figure Description

Detailed Implementation

[0030] Figure 1-19 illustrates a seating arrangement 1 for a transport vehicle 101, particularly for a passenger transport vehicle, wherein the seating arrangement 1 can be arranged on or within the transport vehicle 101 via a fastening device 5, wherein the seating arrangement 1 is intended and adapted to provide a seating position at standing height, wherein the seating arrangement 1 includes a frame element 2, 2a, 2b arranged on the fastening device 5 via at least one mounting shaft 22, wherein at least one receiving device 23, 23a, 23b is arranged on a fastening element 25, the fastening element 25 being configured as arm elements 25, 25a, 25b extending along the height axis Z. Hereinafter, a coordinate system having a height axis Z, a width axis Y, and a depth axis X is used for the seating arrangement. A coordinate system having a height axis Z', a width axis Y', and a depth axis X' is used for at least one frame element. Each axis may also have two directions. At least one frame element 2, 2a, 2b includes an upper region 3 and at least one seat region 4, 4a, 4b, the upper region 3 for supporting the backrest, and the at least one seat region 4, 4a, 4b integrated into the at least one frame element 2, 2a, 2b. Therefore, the at least one frame element 2, 2a, 2b functions as both a backrest and a seat. Thus, an extremely simple and inexpensive seating device 1 is provided.

[0031] exist Figures 1a to 2b and Figure 4 In the image, the seat assembly 1 is shown, which consists only of the frame element 2 arranged on the fastening device 5. Figures 5 to 13 The seat assembly 1 is shown, which includes two frame elements 2, 2a, and 2b respectively. Figure 3 Various pivoting positions are shown, applicable to both seating devices 1 with one frame element 2 and seating devices 1 with two frame elements 2, 2a, 2b. A seating device 1 is provided and adapted to provide a seated position at standing height. This type of seat 1 is also referred to as a sit-stand seat. The seating area is preferably arranged at a height between 40cm and 150cm, more preferably between 50cm and 130cm. The seat height can advantageously match the intended target person. Figure 1a , 1b A seating device 1, for example, more suitable for children or the elderly, is shown. The seat height is preferably in the range of 40cm and 60cm. Figure 2a and 2b A seating device 1 more suitable for adults is shown. The seat height will be in the range of 80cm to 150cm, more preferably in the range of 90cm to 130cm.

[0032] In the construction of a seat assembly 1 having one frame element 2, 2a, 2b and in the construction of a seat assembly 1 having two frame elements 2, 2a, 2b, at least one frame element 2, 2a, 2b can be constructed identically. At least one frame element 2, 2a, 2b is formed by a lower portion 7 and an upper portion 8. The lower portion 7 includes at least one first transverse portion 9 extending substantially along the width axes Y', Y and a second transverse portion 10 extending substantially along the width axes Y', Y. The first and second transverse portions are preferably formed integrally or in one piece. The first transverse portion 9 and the second transverse portion 10 may have recesses arranged in a honeycomb lattice structure (e.g., see...). Figure 15As a result, the lower part 7 can have a very light weight, yet still possess sufficient stability. The upper part 8 also includes a third transverse portion 11 extending along the width axes Y, Y'. In this case, the two width axes Y, Y' are aligned. The first transverse portion 9 and the second transverse portion 10 are spaced apart from the third transverse portion 11 along the height axis Z'. The first transverse portion 9 and the second transverse portion 10 are connected by means of two support elements 27. At least one frame element 2, 2a, 2b correspondingly includes an inner surface 28 defined by the upper part 8 and the lower part 7, or by the third transverse portion, the two support elements 27, the first transverse portion 9, and the second transverse portion 10. At least one frame element 2, 2a, 2b is substantially trapezoidal. The width of the third transverse portion 11 is less than the width of the first transverse portion 9 and the second transverse portion 10. The first transverse portion 9 and the second transverse portion 10 extend along the depth axis X' more than the third transverse portion 11. The first transverse portion 9 or the second transverse portion 10 at least partially forms the seating areas 4, 4a, 4b. The lower part 7 and upper part 8 of at least one frame element 2, 2a, 2b are integrally, integrally, or in multiple parts to form at least one frame element 2, 2a, 2b. Figure 4 and 13 The figures show a one-piece design of frame elements 2, 2a, and 2b within the area enclosed by dashed lines. These figures also show another embodiment of frame elements 2, 2a, and 2b, wherein the frame elements are formed in two parts. For this purpose, at least one frame element comprises a lower part 7 and an upper part 8, in which case both the lower part 7 and the upper part 8 are U-shaped. For this purpose, the two support elements 27 are advantageously interrupted and connected by a detachable connection, preferably a plug connection. This releasable connection, for example, is a plug connection. The two parts of the support elements are preferably inserted into each other. A safety device, such as a pin, screw, bolt, etc., is also advantageously provided to prevent accidental loosening of the plug connection.

[0033] At least one frame element 2, 2a, 2b is pivotable relative to the fastening device 5 about a pivot axis 6 extending along the width axis Y. At least one frame element 2, 2a, 2b is pivotable integrally relative to the pivot axis 6. Therefore, the upper region 3 for supporting the backrest and the integrated seat regions 4, 4a, 4b simultaneously pivot or rotate about the pivot axis 6. In contrast, in conventional seating arrangements, only the backrest can pivot about the pivot axis. Preferably, at least one frame element 2, 2a, 2b is pivotable to at least two pivot positions 12a, 12b, 12c. More preferably, at least one frame element 2, 2a, 2b is pivotable to three pivot positions 12a, 12b, 12c. These pivot positions 12a, 12b, 12c are, for example, in… Figure 3The figure shows a double arrow 15, which again indicates the pivoting direction. At least one frame element 2, 2a, 2b can pivot to a first pivot position 12a, in which the at least one frame element 2, 2a, 2b extends substantially perpendicular to a first imaginary plane 13, which extends parallel to the floor 102 of the vehicle 101. In other words, at least one frame element 2, 2a, 2b extends vertically or substantially parallel to the height axis Z of the seating assembly 1 in the first pivot position. In this pivot position, the seating assembly 1 has only minimal space requirements along the depth axis, which substantially corresponds to the range of the first lateral portion 9 and the second lateral portion 10. At least one frame element 2, 2a, 2b can pivot to a second pivot position 12b, which is inclined at an angle α relative to the first pivot position 12a. Furthermore, at least one frame element 2, 2a, 2b can pivot to a third pivot position 12c, which is inclined at an angle β relative to the first pivot position 12a. A second imaginary plane 14 can be defined, extending perpendicular to the first imaginary plane 13. In the first pivot position, at least one frame element 2, 2a, 2b is substantially arranged in the second imaginary plane 14. In the second pivot position 12b and the third pivot position 12c, at least one frame element 2, 2a, 2b includes an angle α or β relative to the second imaginary plane 14, respectively. In this case, at least one frame element 2, 2a, 2b is inclined in opposite directions along the depth axis X in the second pivot position 12b and the third pivot position 12c. Therefore, the angles α and β have different signs (±), but the same amount. The tilt angles α and β are preferably in the range of 10° to 80°, more preferably in the range of 20° to 70°, in which case at least one frame element 2, 2a, 2b and the second imaginary plane 14 include tilt angles α and β.

[0034] Furthermore, a latching device 29 is provided, by which at least one frame element 2, 2a, 2b can be locked in at least one pivoting position 12a, 12b, 12c. Preferably, at least one frame element 2, 2a, 2b can be locked in a first pivoting position 12a, a second pivoting position 12b, and a third pivoting position 12c. It is also conceivable that at least one frame element 2, 2a, 2b can be locked only in the second pivoting position 12b and the third pivoting position 12c. It is also conceivable that at least one frame element can occupy at least the second and third pivoting positions without being latched. Due to the tilt and advantageous stop of at least one frame element, the frame element remains in the corresponding pivoting position 12b, 12c even without any further locking. When the user occupies the seating device, at least one frame element remains in the pivoting position 12b, 12c. In the second pivot position 12b of at least one frame element 2, 2a, 2b, a first seating region 4, 4a is formed at least by a first transverse portion 9. This is, for example, in Figure 1a and 2a As shown in the diagram. In the third pivot position 12c of at least one frame element 2, 2a, 2b, the second seat regions 4, 4b are formed by at least the second lateral portion 10. This is, for example, in... Figure 1b and 2b As shown in the diagram. In the second pivot position 12b of at least one frame element 2, 2a, 2b, the first seat regions 4, 4a extend substantially parallel to the first imaginary plane 13. In the third pivot position 12c of at least one frame element 2, 2a, 2b, the second seat regions 4, 4b extend substantially parallel to the first imaginary plane 13. This substantially parallel extension of the first or second seat regions 4, 4a, 4b allows the occupant to be seated comfortably.

[0035] Figures 11a-11d and 12a-12d show a seat assembly 1 with two frame elements 2, 2a, 2b, positioned at different pivot positions 12a, 12b, 12c. Figures 11a-11d differ from Figures 12a-12d in the design of the fastening device 5. However, the seat assembly 1, including the fastening device 5 according to any other possible configuration, could also be positioned at the shown pivot positions. In Figures 11a and 12a, the two frame elements 2, 2a, 2b are in a second pivot position 12b. Each frame element 2, 2a, 2b thus provides a first seat area 4, 4a in the form of a first lateral portion 9. In Figures 11d and 12d, the two frame elements 2, 2a, 2b are in a third pivot position 12c. Each frame element 2, 2a, 2b thus provides a second seat area 4, 4b in the form of a second lateral portion 10. In Figures 11b and 12b, the first frame element 2a is in the second pivot position 12b, resulting in the provision of the first seat areas 4, 4a in the form of a first lateral portion 9. The second frame element 2b is in the third pivot position 12c, resulting in the provision of the second seat areas 4, 4b in the form of a second lateral portion 10. In Figures 11c and 12c, the first frame element 2a is in the third pivot position 12c, resulting in the provision of the second seat areas 4, 4b in the form of a second lateral portion 10. The second frame element 2b is in the second pivot position 12b, resulting in the provision of the first seat areas 4, 4a in the form of a first lateral portion 9. This design allows for flexible and individual coordination of seat assemblies composed of such seat devices 1.

[0036] At least one frame element 2, 2a, 2b is arranged on the fastening device 5 via a mounting shaft 22. The mounting shaft 22 is received in at least one receiving device 23, 23a, 23b of the fastening element 5 in such a way that the mounting shaft 22 is non-rotatably connected to the fastening device 5. Furthermore, the mounting shaft 22 extends through a through-channel 24 of at least one frame element 2, 2a, 2b, resulting in at least one frame element 2, 2a, 2b being arranged to pivot relative to the fastening device 5 or the mounting shaft 22. The mounting shaft 22... Figure 4 As shown in detail in 13 and 15 to 17c. The mounting shaft 22 is substantially constructed as a hollow cylinder with a substantially circular cross-section, for example, constructed as a profile tube.

[0037] Mounting shaft 22 has at least one, in the present case, two stop elements 30, 31. These stop elements 30, 31 are designed as recesses in the side surface 33 of the mounting shaft. The recesses preferably extend along the width axis Y over the entire extent of the mounting shaft 22. At least one, in the present case, two other stop elements 32a, 32b are arranged in the through channel 24. These two other stop elements 32a, 32b are constructed as protrusions on the inner surface 24a of the through channel 24. The protrusions preferably extend along the width axis Y over the entire extent of the through channel 24. The through channel 24 may extend along the entire width of at least one frame element 2, 2a, 2b or at least along a substantial portion of the width. The substantial portion is at least half, preferably at least three-quarters, of the total width of the frame elements 2, 2a, 2b. The stop elements 30, 31 of the mounting shaft 22 and the other stop elements 32a, 32b of the through channel 24 are arranged diametrically opposite each other. However, it is conceivable that only one stop element 30, 31, 32a, 32b is arranged on the mounting shaft 22 and the through channel 24. The side surface 33 of the mounting shaft 20 has two outer regions 34, and the inner surface 24a of the through channel 24 abuts against these outer regions 34 in a manner that allows rotation of at least one frame element 2, 2a, 2b relative to the mounting shaft 22. Stop elements 30, 31 are provided in the form of recesses between the two outer regions 34 along the circumferential direction 35 of the mounting shaft 22. The radius 36 of the inner surfaces 30a, 31a of the stop elements 30, 31 is therefore smaller than the radius 37 of the outer regions 34. Figures 15 to 17c As shown, the inner surfaces 30a and 31a are designed to bend outwards. During the pivoting movement of at least one frame element 2, 2a, 2b, at least one other stop element 32a, 32b of the through channel 24 is displaced relative to the mounting shaft 22 along the circumferential direction 35. The other stop elements 32a, 32b, designed as protrusions, extend into the stop elements 30, 31, designed as recesses on the mounting shaft. The stop elements 30, 31 each have two stop surfaces 30b, 31b, 30c, 31c, which represent transitions to adjacent outer regions 34. In the second pivot position 12b and the third pivot position 12c, the other stop elements 32a, 32b, configured as protrusions, are located on the diametrically opposed stop surfaces 30b, 31b, 30c, 31c of the stop elements 30, 31, which are designed as recesses.

[0038] Furthermore, a latching device 29 is provided, which can lock the pivoting positions 12a, 12b, 12c that may arise from pivoting. The latching device 29 is arranged on or below at least one frame element 2, 2a, 2b. This is in Figure 14 As an example, the latching device 29 is shown in the diagram. Figures 16 to 17c It is shown in detail in the text. Figure 17c The second pivot position 12b is shown. Figure 17b The third pivot position 12c is shown. The first pivot position is at... Figure 16 and 17a As shown in the image. For clarity, in... Figures 17a to 17cOnly some particularly relevant reference numerals are shown in the figures. The latching device 29 includes a first locking element 42 that can engage with at least one other locking element 46 of the mounting shaft 22. The other locking elements 46 of the mounting shaft 22 are assigned to each pivot position 12a, 12b, 12c of at least one frame element 2, 2a, 2b. Furthermore, the latching device 29 includes an operating element 39 through which the first locking element 42 can be displaced. In this case, by displacing the first locking element 42, engagement with at least one other locking element 46 of the mounting shaft 22 can be released. Additionally, the latching device 29 includes a retaining element 38, through which the latching device 29 is arranged along the height axis Z' on at least one frame element 2, 2a, 2b, preferably on the underside of at least one frame element 2, 2a, 2b, and more preferably on the lower portion 7 of at least one frame element 2, 2a, 2b. The retaining element 38 is fixed to the frame elements 2, 2a, 2b by a clamp connection. However, other connections are also contemplated. An operating element 39 is arranged on a retaining element 38, in which case a mounting element 40 is provided between the retaining element 38 and the operating element 39. The operating element 39 is pivotally attached to the first locking element 42 by means of a shaft 41, and is therefore rotatable. The mounting element 40 is guided in a guide 38e of the retaining element 38. The first locking element 42 is configured as a pin or bolt. Furthermore, a reset device 43 in the form of a compression spring element is provided. It is actuated or compressed during displacement movement to release engagement. After actuation of the operating element 39, the first locking element 42 can be displaced by the reset device 43, thereby engaging with at least one other locking element 46 of the mounting shaft 22. The reset device or compression spring 43 is arranged between the locking element 42 and the retaining element 38. For this purpose, the first locking element 42 has a radially outwardly projecting flange on which the compression spring is placed. Therefore, the locking element 42 is subjected to a spring force that radially inwardly compresses the first locking element 42. In the unused state, the locking element 42 engages in other locking elements 46 of the mounting shaft 22, which are designed as recesses or holes. Preferably, multiple recesses 46 are provided. These recesses 46 are arranged in the outer region 34 of the side surface 33 along the circumferential direction of the mounting shaft 22. Advantageously, three recesses 46 are provided. The arrangement of the recesses 46 is configured such that in predetermined pivot positions 12a, 12b, 12c, the first locking element 42 can engage in the recess 46 respectively assigned to that pivot position. The first locking element 42 protrudes through an opening 38a of the retaining element 38, which is surrounded by an outwardly extending protruding flange 38b. The reset device rests internally against the protruding flange 38b. Two support portions 39a, 39b are located on each of these flanges 38b. The first support portion 39a is opposite the second support portion 39b along the circumferential direction 44. The operating element 39 includes two operating portions 39c, 39d.The first operating portion 39c is opposite the second operating portion 39d along the circumferential direction 44. Compared to the support portions 39a and 39b, the operating portions 39c and 39d are located further outward along the circumferential direction 44 and along the radial direction 45. When the latching device 29 is operated, one of the operating portions 39c and 39d is pressed inward in the radial direction 45. Therefore, the corresponding operating portions 39c and 39d can be moved into the corresponding recessed areas 38c and 38d of the retaining element 38. Due to the spacing between the operating portions 39c and 39d and the support portions 39a and 39b, and the support portions 39a and 39b on the flange 38b, a lever force acts on the shaft 41, which is arranged in the center of the operating element 39 and connects it to the first locking element 42. The first locking element 42 is correspondingly displaced outward in the radial direction 45. This displacement occurs against the elastic force of the compression spring 43, thereby compressing the compression spring 43. The first locking element 42 is released from displacement of the corresponding recess 46, and at least one frame element 2, 2a, 2b can be pivoted.

[0039] Figure 16 The unused position is shown, in which at least one frame element 2, 2a, 2b is located in the first pivot position 12a. Each of the other stop elements 32a, 32b of the through channel 24 is substantially centered along an imaginary arc 47a, 47b of the first stop element 30 or the second stop element 31. This imaginary arc 47a, 47b extends between the first stop surfaces 30b, 31b and the second stop surfaces 30c, 31c in each case. A first locking element 42 engages in a central recess 46 on the outer region 34, and thus locks the first pivot position 12a. In this first pivot position 12a, at least one frame element 2, 2a, 2b is generally positioned substantially perpendicular to the first imaginary plane 13 and is therefore in a retracted position. Figure 17a At least one frame element 2, 2a, 2b in the first pivot position 12a is shown in two views. In the top view, the first operating portion 39c of the operating element 39 has been actuated and thus moved radially inward into the first recessed region 38c of the retaining element 38. In the bottom view, the second operating portion 39d has been actuated and thus moved radially inward into the second recessed region 38d of the retaining element 38. The first locking element 42 is thus released from engagement with the recess 46, and at least one frame element 2, 2a, 2b can pivot to the desired pivot position. Figure 17bAt least one frame element 2, 2a, 2b is located in the second pivot position 12b. A first additional stop element 32a of at least one frame element 2, 2a, 2b abuts against the first stop surface 30a of the first stop element 30. A second additional stop element 32b of at least one frame element 2, 2a, 2b abuts against the second stop surface 31b of the second stop element 31. Forces applied by the user to at least one frame element 2, 2a, 2b are guided by these stop surfaces 30a, 31b from at least one frame element 2, 2a, 2b into the mounting shaft 22 and thus into the fastening device 5. At least one frame element 2, 2a, 2b is locked in the second pivot position 12b because the first locking element 42 of the latching device 29 engages in a recess 46 on the mounting shaft 22 corresponding to the second pivot position 12b. Figure 17c At least one frame element 2, 2a, 2b is located in the third pivot position 12c. A first additional stop element 32a of at least one frame element 2, 2a, 2b abuts against a second stop surface 30b of the first stop element 30. A second additional stop element 32b of at least one frame element 2, 2a, 2b abuts against a first stop surface 31a of the second stop element 31. Forces applied by the user to at least one frame element 2, 2a, 2b are guided by these stop surfaces 30b, 31a from at least one frame element 2, 2a, 2b into the mounting shaft 22 and thus into the fastening device 5. At least one frame element 2, 2a, 2b is locked in the third pivot position 12c because the locking element 42 of the first latching device 29 engages in a recess 46 on the mounting shaft 22 corresponding to the third pivot position 12c.

[0040] Therefore, the tilt angles α and β are predetermined by the lengths of the imaginary arcs 47a and 47b. Furthermore, it is conceivable that the operating element 39 is arranged at different locations on at least one frame element 2, 2a, 2b. For example, the operating element 39 may also be arranged on the upper portion 8 of at least one frame element 2, 2a, 2b. Additionally, a gripping element 16 may be provided, arranged on the upper portion 8. The operating element 39 may be integrated into the gripping element 16. With this configuration, the operating mode for actuating the first locking element 42 described at the beginning can be maintained. The (lever) force acting on the shaft 41 described above can be transmitted from the operating element 39 to the shaft 41 via a transmission mechanism. Such a (mechanical) transmission mechanism may be, for example, a Bowden cable, a joystick, or a gear-based transmission mechanism. These transmission mechanisms may preferably be arranged within or above at least one frame element 2, 2a, 2b. However, it is also conceivable that the transmission mechanism transmits an electrical signal controlling the actuator. The actuator then actuates the first locking element 42.

[0041] Seat cover 18 is disposed on or within at least one frame element 2, 2a, 2b. Seat cover 18 is in or above an inner surface 28 surrounded by frame elements 2, 2a, 2b or by an upper portion 8 and a lower portion 7. If at least one frame element 2, 2a, 2b is integrally or in one piece, then seat cover 18 can be a tubular design. Therefore, a portion of the tubular seat cover 18 can advantageously be disposed on each side above the inner surface 28. For example, this is in Figure 18a and 18b As shown in the diagram. The tubular seat cover 18 includes a first upper open side 48a along the height axis Z', which is preferably closed by a seam and adjacent to the third transverse portion 11. Furthermore, the tubular seat cover 18 includes a second open side 48b, which is lower along the height axis Z', and is preferably closed by means of an openable closure and located on the top or bottom portion 7. In cases where at least one frame element 2, 2a, 2b is a two-piece construction, a flat seat cover 18 can be used. This is in... Figures 1a to 2b As shown in Figures 5 to 12d. The edge of the seat cover 18 is connected from the bottom upwards to at least one frame element 2, 2a, 2b. The seat cover 18 is connected to two support elements 27 and a third transverse portion 11. For this purpose, for example, a piping track may be arranged inside the two support elements 27 and the third transverse portion 11. The piping track is disposed on the inside of at least one frame element 2, 2a, 2b and thus faces the inner surface 28. The seat cover 18 has a piping lug that is arranged or clamped in the piping track.

[0042] The seat cover 18 is advantageously a knitted fabric. This knitted fabric is advantageously made by a knitting machine. This advantageous use of knitted fabric allows for a high degree of variability in the design of areas with different elasticities. Such a knitted fabric has both flexible and rigid or fixed portions, and can be produced very simply and inexpensively compared to woven fabrics. Advantageously, the knitted fabric is produced using a 3D knitting method. This advantageous technique allows both flexible and rigid areas to be incorporated into the knitted portion. Advantageously, the seat cover 18 has at least two areas 19, 20 with different elasticities. The first area 19 is less elastic than the second area 20. The second area 20 is elastically deformable under force. The first area 19 is arranged above the second area 20 along the height axis Z'. Thus, the first area 19 can be provided and adapted to support the user's shoulder area. Then, the second area 20 with higher elasticity can be arranged along the height axis Z' in the middle and / or lower part or above the inner surface 28. Such a second area 20 can be provided and adapted to support the user's lower back and hip area. Of course, it is also conceivable to provide other areas with different elasticities in the seat cover. Furthermore, the seat cover 18 is connected from the bottom upwards to at least one frame element 2, 2a, 2b at its edge. Under the action of force, the second region 20 forms a three-dimensional deformation 21 or a protrusion. This is in Figure 3 The force is schematically shown in the diagram. It is applied by the user's leaning motion. Therefore, when pivoting from the second pivot position to the third pivot position or vice versa, a force is applied in the opposite direction, resulting in three-dimensional deformation also developing in the opposite direction. The seat cover 18 may have a third region 49 arranged below the second region along the height axis Z'. This third region 49 can be connected to at least one frame element 2, 2a, 2b by a preferably detachable connection. The third region 49 can be arranged on the first transverse portion 9 and the second transverse portion 10 and serve as a seat trim. This is, for example, in… Figure 18a and 18b As shown in the diagram. The seat cover 18 may also have a central space or cutout 50. Thus, the third region 49 and the second region 20 are connected only by a mesh portion arranged on the support element 27 of at least one frame element 2, 2a, 2b. Alternatively, the second region 20 may be continuously incorporated into the third region 49. This is in... Figure 5 The example is shown below.

[0043] The seating areas 4, 4a, 4b can be further expanded by providing at least one additional element 17, which is arranged on the lower portion 7 of at least one frame element 2, 2a, 2b. The depth extension of the seating areas 4, 4a, 4b is increased by the additional element 17. The additional element 17 can be arranged on the upper surface of the first transverse portion and / or the second transverse portion, or it can be arranged near the upper surface of the first transverse portion and / or the second transverse portion. Such an additional element... Figure 3 As shown, the seat cover 18 can be attached to frame elements 2, 2a, 2b via friction connections and / or positive-locking connections. Possible connections include clamp connections, screw connections, plug connections, etc. Additional elements 17 can also be provided to secure the seat cover 18. Thus, an effective seat surface in contact with the user can be defined. The effective seat surface advantageously includes a first seat region 4a or a second seat region 4b, and is preferably oriented substantially horizontally or parallel to a first imaginary plane 13. This effective seat surface is provided by either the first or second seat region, depending on the pivot positions 12b, 12c. The effective seat surface can be provided at least partially by the upper surface of the first transverse portion 9 or the upper surface of the second transverse portion 10. However, it is also conceivable that other elements, other layers, coverings, decorations, etc., can be arranged on the upper surfaces of the transverse portions 9, 10, and then at least partially form the effective seat surface. Additional elements 17 can also enhance the effective seat surface. The effective seat surface can preferably be formed at least partially by additional elements 17. However, it is also conceivable to arrange additional layers, coverings, decorations, etc., on the additional element 17, thereby forming at least partially an effective seat surface. The effective seat surface advantageously includes a first seat region 4a or a second seat region 4b of at least one frame element 2, 2a, 2b and a portion of the second region 20 of the seat cover 18. The effective seat surface may also include a transition region between the third region 49 of the seat cover 18 and the second region 20.

[0044] Furthermore, on at least one frame element, at least one gripping element 16 is arranged on at least one support element 27 or upper part 8. The gripping element is typically arranged on the outer side of the seat assembly 1, which is located on the aisle of the vehicle. If two aisles are provided, then of course, gripping elements 16 can also be provided on each outer side of the seat assembly 1.

[0045] Figures 1a to 2b and Figure 4A seat assembly 1 with only one frame element 2 is shown. The fastening device 5 includes two fastening elements 25 in the form of arm elements 25a, 25b, which extend along the height axis Z and lead to a base element 26. Starting from the base element 26, the arm elements 25a, 25b also extend along the width axis Y, such that they extend obliquely upwards. The distance 53 between the first arm element 25a and the second arm element 25b decreases downwards along the height axis Z. The arm elements 25, 25a, 25b each have receiving devices 23, 23a, 23b at their upper ends for mounting a shaft 22. The receiving devices 23, 23a, 23b can be formed integrally, in one piece, or in multiple pieces with the arm elements. In the transition region leading to the receiving devices 23, 23a, 23b, the arm elements 25, 25a, 25b are advantageously oriented substantially parallel to the height axis Z. In the middle or lower regions of the arm elements 25a and 25b, they are inclined relative to a reference axis 61 extending perpendicularly to the first imaginary plane 13. Therefore, an inclination angle γ can be defined between this reference axis 61 and the central axis 62 of the arm elements 25a and 25b. This inclination angle γ depends on the ratio of the width extension of the base element 26 to the width extension of the mounting shaft 22. This is in Figure 8a and 10a The example is shown in the figure. The tilt angle γ is in the range of 5° to 30°, preferably in the range of 10° to 20°. The arm elements 25, 25a, 25b can be designed with a flat profile. In this flat profile, a preferred circular recess can form the receiving devices 23, 23a, 23b. Furthermore, the receiving devices 23, 23a, 23b can be designed to be substantially cylindrical, having a preferably circular lateral portion. The base element 26 has a smaller range along the width axis Y than the mounting axis 22, or as the distance between the receiving devices 23, 23a, 23b. In addition, cover elements 51 are provided on the sides of the receiving devices 23, 23a, 23b. Figures 1a to 2b As shown in Figure 4, the arm elements can extend substantially in a straight line or in a V-shape. However, a generally S-shaped or arcuate range for the arm elements 25, 25a, 25b is also conceivable. The base element 26 is either directly fixed to the floor 102 of the transport vehicle 101 or displaceably arranged on the floor 102 of the transport vehicle 101 via a guide device. This configuration has the advantage that the base element is centrally located below at least one frame element 2, 2a, 2b. Therefore, forces can be symmetrically introduced into the base element 26. This allows for a simpler design of the guidance system. For example, if a track system is used as the guidance system, only one track is sufficient. Figure 1a and 1bThe seat 1 includes a low-height fastening device 5. The base element 26 is configured only as a transverse support extending along the width axis Y and / or a flat profile. This seating device 1 can be used, for example, by the elderly or children. Figure 2a and 2b A seat assembly 1 with a seat height suitable for adults is shown. The base element 26 is designed as a substantially rectangular element comprising two transverse supports extending along the width axis Y. The upper transverse support along the height axis Z serves as a foot support area 52. It is also conceivable that a rotating device is arranged on or within the base element 26, or integrated therein. The fastening device 5 or the seat assembly 1 can then be rotated about a rotation axis 54 extending parallel to the height axis Z. This is in… Figure 1b In 2b and 3, it is indicated by the double arrow 55.

[0046] according to Figures 5 to 13 The embodiment illustrates a seat assembly 1 having two frame elements 2, 2a, 2b, arranged on a fastening device 5. The two frame elements 2, 2a, 2b are arranged side-by-side along a width axis Y. As already described, the two frame elements 2, 2a, 2b can be independently pivoted relative to the fastening device 5 about a common pivot axis 6 extending along the width axis Y to a first pivot position 12a, a second pivot position 12b, and a third pivot position 12c. The fastening device 5 can be designed in various ways. In all embodiments, a mounting shaft 22 is provided, extending along the seat assembly and through a through-channel 24 of each of the two frame elements 2, 2a, 2b. As already described, such through-channels 24 can extend substantially over the entire width of the frame elements 2, 2a, 2b. Partial extension is also conceivable. A latching device 29 is also provided on each of the two frame elements 2, 2a, 2b. The mounting shaft 22 is received in the two receiving devices 23, 23a, 23b of the fastening device 5. Figure 13 It shows something similar to Figure 4 An exploded view of the seating arrangement. However, in Figure 13 Only three possible configurations of the fastening device 5 are shown. Of course, other fastening devices 5 shown can also be inserted. Figure 13 In these embodiments, at least one cover element 51 may also be provided to enclose the mounting shaft 22. The mounting shaft 22 is received in at least two receiving devices 23, 23a, 23b of the fastening device 5. Each receiving device 23, 23a, 23b is arranged on the fastening element 25. Figure 5In the embodiment shown in Figure 11d, the first receiving device 23a is arranged between the first frame element 2a and the second frame element 2b. Another second receiving device 23b is arranged on the side of one of the two frame elements 2a, 2b, or on one of the two outer sides of the seat assembly 1. Both receiving devices 23, 23a, 23b are substantially cylindrical, having substantially circular lateral portions.

[0047] according to Figures 5 to 6d In one embodiment, the second receiving device 23b is arranged on the fastening element 25 in the form of a first plate-like element 56, which can be fastened to the wall element of the transport vehicle 101. The first plate-like element 56 is thus arranged in a fastening plane 58 (see FIG. 6c), which extends substantially parallel to the second imaginary plane 14. The wall element of the transport vehicle 101 advantageously includes the fastening plane 58. The first receiving device 23a is arranged on the fastening element 25 in the form of an arm element 25. The arm element 25 is designed as an extendable arm or cantilever. The arm element 25 thus extends from the first receiving device 23a to the fastening plane 58 and terminates at a second plate-like element 57, which is also arranged in the fastening plane 58 and can be arranged on the wall element of the transport vehicle. Starting from the second plate-like element 57, the lower cantilever portion of the arm element 25 extends obliquely upward along the height axis Z. The lower cantilever portion forms an angle θ1 with the first imaginary plane 13, which is in the range of 10° and 45°. The upper portion of the arm element 25, which is adjacent to the lower portion, forms an angle θ2 with the first imaginary plane 13, which is in the range of 45° to 90°. Figure 5 A perspective view of this embodiment is shown. Figure 6a Figure 6a shows a front view of this embodiment, and Figure 6b shows a rear view of this embodiment. Figure 6c shows a side view of this embodiment. Figure 6d A bottom view of this embodiment is shown. The embodiments according to Figures 11a to 11d are similar to those according to... Figures 5 to 6d The only difference in this implementation is that only a third plate-shaped element 59 is provided. This third plate-shaped element 59 also extends in the fixed plane 58. Furthermore, the second receiving device 23b is arranged on this third plate-shaped element 59. Similarly, the arm element 25 leads to the third plate-shaped element 59. Therefore, the third plate-shaped element 59 can also be understood as a combination of the first plate-shaped element 56 and the second plate-shaped element 57. The plate-shaped elements 57, 58, and 59 also have means through which they can be fastened to a transport vehicle. These are, for example, holes for corresponding threaded connections. Of course, it is conceivable that other similar fastening techniques can be considered.

[0048] According to Figures 7 to 10dIn one embodiment, two fastening elements in the form of arm elements 25, 25a, and 25b are provided, on which receiving devices 23, 23a, and 23b are arranged or integrated. Figure 7 A perspective view of the first embodiment is shown. Figure 8a Figure 8a shows a front view of the first embodiment, and Figure 8b shows a rear view of the first embodiment. Figure 8c shows a side view of the first embodiment. Figure 8d A bottom view of the first embodiment is shown. Figure 9 A perspective view of the second embodiment is shown. Figure 10a A front view of this second embodiment is shown. Figure 10b A rear view of this second embodiment is shown. Figure 10c A side view of this second embodiment is shown. Figure 10d A bottom view of this second embodiment is shown. According to... Figures 7 to 10d In these embodiments, the two arm elements 25, 25a, 25b are configured with a flat profile and can be fixed to the floor of the transport vehicle 101. For this purpose, a fastening region 60 is formed on the respective arm elements 25, 25a, 25b, the fastening region 60 having a portion parallel to the floor of the transport vehicle. Holes can be provided in this portion, by means of which fastening can be performed, for example, by a threaded connection. The two arm elements 25, 25a, 25b are inclined relative to a reference axis 61, which extends perpendicularly to a first imaginary plane 13. Therefore, an inclination angle γ can be defined between the reference axis 61 and the central axis 62 of the arm elements 25, 25a, 25b. This... Figure 8a and 10a The example is shown in the figure. The tilt angle γ is in the range of 5° to 20°, preferably in the range of 10° to 15°. Advantageously, the second receiving device 23b and the second arm element 25b connected thereto are disposed on the outer side of the seat assembly 1, on which the gripping element 16 is also provided. As a result, the force introduced into the seat assembly 1 by a gripping element 16 can be effectively transferred by the second arm element 25b. Therefore, the seat assembly 1 has advantageously increased stability on the outside of the seat assembly 1. As in all the embodiments shown, the arm elements 25, 25a, 25b and the associated receiving devices 23, 23a, 23b can be designed integrally, as a single piece or in multiple pieces. Similarly, the through channel 24 can extend substantially over the entire width of the frame elements 2, 2a, 2b or only partially. For example, in Figure 8dAs can be seen, the through channel 24 extends only in the portion along the width axis Y'. In this case, the two receiving devices 23, 23a, 23b include extension elements 63 extending along the width axis Y' of the frame elements 2, 2a, 2b. The receiving devices 23, 23a, 23b and the corresponding extension elements 63 can be formed integrally, as a single piece, or in multiple pieces. The extension element associated with the first receiving device 23a extends from the intermediate space between the frame elements 2, 2a, 2b along the second frame element 2b. The extension element associated with the first receiving device 23a extends from the outside along the first frame element 2a to the intermediate space between the frame elements 2, 2a, 2b. In contrast, according to Figure 10d The through channel 24 of the embodiment shown extends over a substantial portion of the width of the frame elements 2, 2a, 2b. The substantial portion should be understood to refer to at least half, preferably three-quarters, of the total width of the frame elements 2, 2a, 2b. According to... Figures 7 to 8d In this embodiment, a foot pedal 52 or foot pedal element is provided on each arm element 25, 25a, 25b. Starting from the corresponding arm element 25, 25a, 25b, the foot pedal 52 extends substantially parallel to the first imaginary plane 13, or more precisely, substantially parallel to the floor of the transport vehicle. Furthermore, the foot pedal 52 is substantially designed with a flat profile, and is designed integrally or as a single piece with the corresponding arm element 25, 25a, 25b.

[0049] According to the embodiments shown in Figures 12a to 12d, the first receiving devices 23, 23a and the second receiving devices 23, 23b of the fastening device 5 are arranged on the outside of the seat assembly 1. Therefore, two frame elements 2, 2a, 2b are arranged between the receiving devices 23, 23a, 23b. Only a spacer element 64, preferably sleeve-shaped, is provided between the two frame elements 2, 2a, 2b. This fastening device 5 is based on a similar embodiment... Figure 2a and 2b The fastening device is designed accordingly. Therefore, the corresponding description is similar. Two arched S-shaped or V-shaped fastening elements 25, in the form of arm elements 25a, 25b, also extend to the base element 26. In the middle or lower region of the arm elements 25a, 25b, they are inclined relative to a reference axis 61 extending perpendicular to the first imaginary plane 13. Therefore, an inclination angle γ can be defined between the reference axis 61 and the central axis 62 of the arm elements 25, 25a, 25b. This inclination angle γ depends on the ratio of the width extension of the base element 26 to the width extension of the mounting shaft 22. The inclination angle γ is in the range of 5° to 60°, preferably in the range of 10° to 50°. Therefore, it is also advantageous to introduce force symmetrically to the base element 26. Similarly, a rotating device can also be provided by which the seat device 1 can be rotated about the rotation axis 54. Furthermore, this embodiment can have the same Figures 1a to 2bOther constructions and advantages are the same as those in the implementation in 4.

[0050] exist Figure 19 The diagram shows an interior device 100 for a transport vehicle 101. This interior device 100 includes a plurality of seating units 1. These seating units 1 are securely fixed to the floor of the transport vehicle 101 or guided in a guidance system (not shown). The guidance system may be, for example, a track system, and is preferably arranged on the floor of the transport vehicle 101. Alternatively, the guidance system may be provided on the wall elements of the transport vehicle 101. Thus, a specific number of seating units 1 can be initially stored in the loading area 103 of the transport vehicle 101. As needed, the required number of seating units 1 can be distributed from the loading area 103 within the interior of the transport vehicle 101 along the guidance system. This can be done manually or by actuators. These seat selections should be modifiable to meet different needs. Such needs include, for example, adjustments to seat orientation relative to the direction of travel or adjustments to the facing seat groups. If luggage or large items are present, fewer seating units 1 can be removed from the loading area. This interior device 100 with seating units 1 can provide more than 25% more seating than previous seating devices. In the first pivot position 12a, that is, the upright position, the seat assembly 1 occupies only the depth of the seat portion 4 of the frame elements 2, 2a, 2b along the depth axis X. Therefore, the seat assembly 1 can be stored in a very space-efficient manner. Similarly, in the second pivot position 12b and the third pivot position 12c, the seat assembly 1 has a relatively small space requirement along the depth axis X. The space requirement in the depth direction is determined by the tilt angles α, β and the required foot space. The user adopts a sitting posture in the seat assembly 1, which roughly corresponds to a standing posture. However, this sitting posture has a significantly lower space requirement compared to a conventional sitting posture, in which the legs are bent at approximately a right angle. The seat assembly 1 advantageously allows for extremely comfortable adjustment of the seat orientation due to its pivotability. This means that the seat assembly can also be easily modified. This is in Figure 19 The following is illustrated by example. Seating assembly 1 has two frame elements 2, 2a, and 2b respectively. The first seat group 104 is a group of four. The two frame elements 2, 2a, and 2b of two consecutive seat assemblies 1 are tilted in a manner that allows two users to face each other. The second seat group 105 is a group of three. Here, frame element 2a is oriented such that the user faces the seat assembly with two frame elements 2a and 2b. The remaining frame elements 2b serve as a single seat 106. In the third seat group 107, the seat assembly 1 serves as a two-seater. In this case, the two frame elements 2a and 2b are tilted or aligned in the same direction.
