[0002] Seating arrangement

[0003] The invention relates to a seat arrangement, in particular for a vehicle for transporting people, comprising at least one seat and at least one support arm arrangement, wherein the support arm arrangement has a wall bracket and a support arm, wherein the wall bracket has a connecting element for connecting the wall bracket to a wall.

[0004] Furthermore, the invention relates to a vehicle for transporting people, comprising at least one such seating arrangement or one further developed as described below.

[0005] Such seating arrangements are usually used on commuter trains, regional trains or S-Bahn trains and are specially adapted to the needs of such trains.

[0006] Document EP 3 676 150 B1 concerns a generic seating arrangement. This has a modular design, but requires a support and, due to the construction used, is relatively heavy and offers limited flexibility with regard to the seating arrangement.

[0007] The known seating arrangements are often heavy, require additional support to the side wall, and are always unique to a specific vehicle. In previous new vehicles, modifications are almost always necessary, or the body shell has to be adapted to the existing seating arrangement. Based on this, the object of the invention is to provide a seating arrangement that offers greater flexibility and lower weight.

[0008] This object is achieved by the seat arrangement of claim 1 and the vehicle of claim 17.

[0009] Advantageous embodiments and further developments are the subject of the respective subclaims.

[0010] According to the invention, a seat arrangement, in particular for a passenger transport vehicle, is provided, comprising at least one seat and at least one support arm arrangement. The support arm arrangement has a wall mount and a support arm. The wall mount has a connecting element for connecting the wall mount to a wall, wherein the wall mount has a connecting piece which is designed for connection to the support arm.

[0011] The seating arrangement is in particular a seating arrangement for a vehicle for the transport of persons.

[0012] The wall is preferably a side wall.

[0013] According to the invention, a vehicle for transporting people is further provided, comprising at least one such seat arrangement or one further developed as described below.

[0014] In one embodiment, the seat assembly is designed as a cantilever assembly. According to the invention, a seat assembly with a modular design is provided, which ensures easy interchangeability.

[0015] This provides a flexible seating arrangement that can be easily adapted to different vehicle types and is constructed from consistent components. The seating arrangement according to the invention can be used for single, double, or four-seater seats. The seating arrangement according to the invention is lighter and more cost-effective than known seating arrangements and offers the advantage of providing the passenger with more legroom.

[0016] Vehicles suitable for passenger transport are specifically adapted to passenger transport.

[0017] The nozzle is preferably substantially cylindrical or hollow cylindrical.

[0018] In the design of the seat arrangement, it can be provided that the support arm has a hollow cross-section, preferably a substantially circular tubular cross-section, which is designed for connection to the nozzle.

[0019] This results in optimized load distribution (through optimized area moment of inertia) and a very attractive appearance.

[0020] By designing a support arm with a hollow cross-section, it is possible for the support arm to be pushed onto the nozzle, and the nozzle is then accommodated by the hollow cross-section of the support arm. Thus, the nozzle disappears within the hollow cross-section when installed.

[0021] Preferably, the support arm is designed as a tube.

[0022] It is possible to achieve a relatively large support arm diameter with a relatively low weight. The diameter of the support arm is preferably between 10 and 20 cm.

[0023] A large tube diameter has a significantly higher area moment of inertia than the known support arms, which is why the seat arrangement usually does not require additional support.

[0024] In a further development of the seat arrangement, it can be provided that the connecting piece has at least one first form-locking element, preferably a groove, extending in a longitudinal direction of the connecting piece, and the support arm has at least one second form-locking element, preferably a projection, extending in a longitudinal direction of the support arm.

[0025] Preferably, the projection is directed inwards.

[0026] This ensures that the nozzle itself already has the first positive locking element and no further elements need to be provided. Furthermore, it is achieved that the support arm itself already has the second positive locking element and no further elements need to be provided in order to create a positive connection between the support arm and the nozzle. A simple and stable construction is provided. In an embodiment of the seat arrangement it can be provided that the at least one first positive locking element is formed on an outer wall of the nozzle, and wherein the at least one second positive locking element is formed on an inner wall of the support arm.

[0027] This ensures that in the assembled state the at least one first form-locking element and the at least one second form-locking element are concealed.

[0028] In a further development of the seat arrangement, it can be provided that the first form-locking element and the second form-locking element are designed to be complementary to one another and together form a first form-locking connection between the connecting piece and the support arm.

[0029] This provides matching form-locking elements on both the nozzle and the support arm, allowing a modular design and interchangeability.

[0030] In an embodiment of the seat arrangement, it can be provided that the seat arrangement has at least one seat fastening element to which the at least one seat is fastened, wherein the at least one seat fastening element is connected, preferably in a form-fitting manner, to the support arm.

[0031] By providing the seat fastening element, a component of the support arm is created that allows the at least one seat to be fastened to the seat fastening element rather than directly to the support arm. The seat fastening element can be individually adapted to the seat, but can be designed consistently with regard to its structure intended for attachment to the support arm. Furthermore, this ensures a modular design.

[0032] In a further development of the seat arrangement, it can be provided that the support arm has at least one third form-locking element, preferably a groove, extending in a longitudinal direction of the support arm.

[0033] This provides a means for mounting different elements of the support arm device on the support arm .

[0034] In an embodiment of the seat arrangement, it can be provided that the at least one third form-locking element is formed on an outer wall of the support arm.

[0035] Preferably, the at least one third form-locking element extends over the entire length of the support arm.

[0036] This allows the elements of the support arm device to be mounted on support arms by sliding them onto the support arm.

[0037] In a further development of the seat arrangement, it can be provided that the at least one seat fastening element has at least one fourth form-fitting element, preferably a projection, extending in a longitudinal direction of the support arm.

[0038] This provides a seat fastening element that has a positive locking element that prevents the seat fastening element from being rotated in the direction of the longitudinal axis of the support arm when it is mounted on the support arm. The seat fastening element can be moved along the support arm during assembly. It is designed to be fixable. Fixing can be achieved, for example, by a force-locking connection such as a screw connection (frictional connection). Jamming is also conceivable.

[0039] In the design of the seat arrangement, it can be provided that the at least one third form-locking element and the at least one fourth form-locking element are designed to be complementary to one another and together form a second form-locking connection between the seat fastening element and the support arm.

[0040] This provides matching form-locking elements on both the support arm and the seat fastening element, allowing a modular design and interchangeability.

[0041] In a further development of the seat arrangement, it can be provided that the at least one seat fastening element has a first connecting section for fastening to the support arm, which has a cross section that partially, preferably half-circumferentially, surrounds the support arm.

[0042] In an embodiment of the seat arrangement, it can be provided that the at least one seat fastening element has a first connection section for fastening to the support arm, which has a cross section that completely, preferably completely, surrounds the support arm.

[0043] This provides a specific connecting section designed to fasten the seat fastening element to the support arm. The cross-section of the connecting section is specifically adapted to the cross-section of the support arm. The provision of a specific connecting section does not result in any further structural limitations of the seat fastening element with regard to other components.

[0044] In the variant in which the connecting section partially, preferably half-circumferentially, surrounds the support arm, there is the advantage that at least one lightweight fastening element is provided, which is / are preferably designed to accommodate a single seat or double seat.

[0045] In the variant in which the connecting section completely, preferably completely, surrounds the support arm, there is the advantage that at least one stable fastening element is provided, which is / are preferably designed to accommodate a four-seater seat (i.e. two double seats).

[0046] In a further development of the seat arrangement, it can be provided that the at least one seat fastening element has at least one support section to which the at least one seat is fastened.

[0047] This defines a region of the at least one seat fastening element that is specifically designed to accommodate the seat. It is possible that this region is specifically adapted to the type or shape of the seat.

[0048] The design of the connecting section for attachment to the support arm remains unchanged, however, with a specific adaptation of the support section. In the design of the seat arrangement, it can be provided that the at least one support section extends transversely to the longitudinal direction of the support arm on one side and / or both sides.

[0049] This makes it possible to flexibly provide the appropriate seat fastening element, depending on whether a single seat, a double seat or a four-seater seat (e.g. two double seats) is to be supported by the support arm.

[0050] In a further development of the seat arrangement, it can be provided that the seat arrangement has a support element for supporting the support arm, wherein the support element has a second connecting section which surrounds the support arm partially, preferably half-circumferentially or completely, preferably fully circumferentially, and wherein the second connecting section preferably has at least one fifth form-locking element extending in a longitudinal direction of the support arm, which is designed to be complementary to the at least one second form-locking element extending in a longitudinal direction of the support arm.

[0051] This ensures that there is a positive connection between the connecting section of the support element and the support arm, so that the support element cannot rotate about the longitudinal axis of the support arm relative to the support arm.

[0052] Alternatively, a support element can also be designed without a form-locking element.

[0053] It can be provided that the support element can be pushed onto the support arm. This can also be done retroactively. Furthermore, the support element can have a support and a support part that can rest on the wall.

[0054] As a result, the support element and the connecting section of the support element can be fixed axially on the support arm.

[0055] Other elements of the seat assembly located between the connecting section of the support element and the wall bracket can also be axially fixed by the support element. Additionally, the support arm can be axially secured by the support element.

[0056] In the embodiment of the seat arrangement, it can be provided that the fifth form-locking element is formed on an inner wall of the connecting section.

[0057] This ensures that a positive connection between the support arm and the connecting section is not visible in the assembled state and that the connecting section has a smooth surface from the outside.

[0058] The vehicle is preferably a track-guided vehicle.

[0059] The track-guided vehicle is, for example, a rail vehicle or a magnetic levitation train, preferably for passenger transport.

[0060] Preferably, the rail vehicle is a commuter train, a regional train or a suburban train. The invention will be described below with reference to several
