Description

technical field

The present invention relates to a passenger transport vehicle. Such a passenger transport vehicle can be designed as a rail vehicle and can be used for the mass transport of people, for example as part of local and long-distance public transport.

Known prior art

It is known that people-carrying vehicles and cars for people-carrying vehicles are individually configured and designed according to specific requirements and needs. In particular, passenger transport vehicles are equipped with different seat configurations.

For example, the U.S. 4,580,832 a passenger seat device for vehicles, in particular an auxiliary seat device which is provided foldable in a wall.

the EP 1 864 850 B1 shows a seat unit with a base arranged on a floor of the vehicle. A secondary seat bottom and seat back are provided in addition to a main seat floor and seat back. These can be moved between a retracted position and an extended position by means of a lateral movement.

Disadvantages of the Prior Art

However, the solutions shown are not designed to be sufficiently variable, in particular to provide a passenger transport vehicle with expanded application options.

problem

It is therefore an object of the present invention to provide a passenger transport vehicle with a flexible seating concept, in which case the passenger transport vehicle can be adapted particularly easily to the transport situation at hand.

Solution according to the invention

The above object is achieved by a passenger transport vehicle according to claim 1.

For an overall contextual understanding of the present disclosure, a longitudinal direction, a horizontal transverse direction oriented perpendicularly to the longitudinal direction and a vertical direction perpendicular thereto are defined, which relate to a car body of the passenger transport vehicle used as intended. Likewise, the passenger transport vehicle thereby defines a horizontal plane. If such reference information, in particular indication of direction, is used in connection with individual components of the passenger transport vehicle, a reference must be made to an intended installation position of this component in the vehicle used as intended. The intended use of the passenger transport vehicle can be defined in such a way that it is positioned on a flat, horizontal and straight surface, for example on a roadway or on rails.

The passenger transport vehicle has a car body with a portal and a portal wall.

The portal can be characterized in that it has a load-bearing structure that differs from the load-bearing structures of walls of the car body. In particular, a portal can have a higher level of rigidity and can serve in particular to stiffen sections of the car body. According to one embodiment, portals run at least partially, in particular essentially completely, in the transverse direction of the passenger transport vehicle. A portal can also be designed in such a way that it narrows a cross section of a passage opening in the longitudinal direction of the passenger transport vehicle, so that in particular a clearance gauge of an interior of the car body or of the passenger transport vehicle in the area of the portal is reduced in comparison to other internal clearance gauges of the passenger transport vehicle.

A portal can be a structural component or section of the passenger transport vehicle or the car body, which is provided, for example, at the end areas of the passenger transport vehicle or a car body. It is also conceivable that such a portal is arranged in a central area or at other locations of the car body.

The portal wall extends over a portal depth that is aligned in the transverse direction of the portal. The transverse direction of the portal runs at least perpendicular to the vertical direction. The term "portal depth" can also be understood as the width of a side of the portal, a portal column or a portal arch.

The passenger transport vehicle also has a folding seat device with a foldable seat device. Furthermore, a fastening device is provided by means of which the Folding seat device is arranged flexibly on the portal wall. The term “flexible arrangement” using the fastening device means that the folding seat device can assume different positions with respect to the portal wall, namely a stowed position and at least one use position, in particular a first seated position and a second seated position.

The flexible fastening device thus makes it possible for the folding seat device to be folded up essentially completely in the stowed position, and for a base area of the passenger transport vehicle directly surrounding the folding seat device to be released for other uses. For example, the released floor space can provide additional standing space for passengers and/or allow passage in the vicinity of the portal or through the portal.

The stowage position can be defined in particular by the fact that a seat surface of the seat device of the folding seat device and/or the entire folding seat device does not protrude beyond the portal depth in the transverse direction of the portal. In this way it is ensured that a base area of the passenger transport vehicle directly surrounding the folding seat device is released for additional use.

The flexible fastening device is designed in such a way that the folding seat device can be moved from the stowed position into at least the first use position. The usage position is defined at least by the fact that a seat surface of the seat device is aligned essentially parallel to a horizontal plane of the passenger transport vehicle, in particular such that a passenger can sit on the seat surface of the seat device. Furthermore, the seat surface at least partially projects beyond the portal wall beyond the depth of the portal, in particular the seat surface projects completely beyond the portal wall in the transverse direction of the portal. A complete protrusion occurs when no significant sections of the seat surface cover the portal wall in the transverse direction of the portal.

According to one embodiment, the folding seat device has a first seat device with a first seat surface and a second seat device with a second seat surface. The folding seat device is designed in such a way that the first seat surface and the second seat surface, located in the stowed position, neither protrude beyond the depth of the portal in the transverse direction of the portal. In the use position, both seat surfaces, the first seat surface and the second seat surface, are arranged substantially parallel to the horizontal plane. Furthermore, the first seat surface and also the second seat surface protrudes beyond the portal wall in the transverse direction of the portal, in particular completely.

The phrase "substantially parallel to the horizontal plane" includes any position that allows a passenger to be seated on the seat surface.

According to one embodiment, the portal and/or the portal wall carrying the folding seat device is/are provided and/or aligned in the car body in such a way, and/or the flexible fastening device is designed in such a way that a seat alignment of the seat device in the use position is either in the longitudinal direction or is aligned in the transverse direction, or that - if each is in the use position - a first seat alignment of the first seat device and / or a second seat alignment of the second seat device are aligned in the longitudinal direction or in the transverse direction.

The term "seat orientation" is defined by an orientation of a seating direction of passengers on a seating arrangement. For example, passengers typically sit in the seat orientation on a seat surface of a seat assembly. That is, a passenger's upper body or knees essentially point in this seat orientation when seated. If the seat device has a backrest with a surface, the seat orientation essentially corresponds to a normal vector of the surface of the backrest.

The flexible fastening device can have at least one or a combination of at least two of the flexible fastening mechanisms described below: a pivoting device that enables pivoting or rotation of the folding seat device or one or both seat devices about an at least partially or essentially exclusively horizontal pivot axis allows; a translation device having guide means for displacing the folding seat device or one or both seat devices at least partially or exclusively along a translation direction running in the portal direction; a device for pivoting and parallel displacement, based on a geometric shape of a parallelogram, the folding seat device or one or both seat devices.

According to one embodiment, the folding seat device is configured such that a seat surface, or both seat surfaces, is/are aligned substantially parallel to the portal wall in the stowed position. In this way, the folding seat device can be stowed in a particularly space-saving manner.

According to a preferred embodiment of the invention, the folding seat device is designed such that the first seat device and the second seat device in the transverse direction of the portal at least partially, in particular completely, overlap in the transverse direction of the portal when the folding seat device with the seat devices is in the stowed position. When the portal wall is viewed perpendicularly, one seat device is located at least partially, in particular completely, behind the other seat device. This configuration results in a further saving in the space required for the folding seat device in the stowed position. The fastening device for fastening the folding seat device to the portal wall and/or the connecting device for connecting the first seat device to the second seat device are configured and designed accordingly for this purpose.

In the context of the embodiment described above, it is conceivable, for example, that the connecting device of the seat devices is provided with a rotation mechanism such that the connecting device—if at least one seat device is in a use position—forms a swing-out axis running in the vertical direction. Correspondingly, one seat device can be swiveled around the other seat device about the vertically extending swing-out axis. In this way, an overlapping of the seat devices can be achieved.

According to the specific embodiment of the passenger transport vehicle, wherein the folding seat device has the first seat device and the second seat device, the connecting device for connecting the first seat device and the second seat device is designed in such a way that a first seat position and a second seat position can be assumed by the seat devices. The first and the second seating position are to be subsumed under the term "useful position".

In particular, the connecting device is designed in such a way that a first seat orientation of the first seat device is oriented in the opposite direction to a second seat orientation of the second seat device. In particular, the seating devices are arranged back to back to one another. Correspondingly, passengers on the seat devices would see in opposite directions, or their backs would be facing each other.

In contrast, in the second seat position, the first seat alignment and the second seat alignment are oriented in the same direction. Consequently, the seat devices are arranged in parallel next to each other and form a double seat.

In particular, the fastening device, folding seat device, first seat device, second seat device, and/or the connecting device are designed in such a way that both seat alignments of the double seat formed by the seat devices are aligned in the longitudinal direction, and that the double seat formed is maximally extended in the transverse direction of the passenger transport vehicle and/or in the transverse direction of the portal a vehicle center protrudes into the interior of the passenger transport vehicle.

The folding seat device, the fastening device, and/or the connecting device is/are consequently designed in such a way that two different usage positions can be assumed by the seat devices as desired, namely the first seat position of the seat devices and the second seat position of the seat devices.

The changeover of the seat devices between the first seat position and the second seat position takes place in particular by pivoting the second seat device about the vertically extending pivot axis of the connecting device.

Furthermore, a locking device is configured and provided in such a way that the first seat device and the second seat device can be fixed in relation to one another in the respective seated position. In particular, the seat devices can be fixed relative to one another in the first seating position and in the second seating position. For example, the locking device can be integrated with the connecting device.

According to one embodiment, a seat device has a backrest, or the first seat device has a first backrest and the second seat device has a second backrest.

In particular, the folding seat device is designed in such a way that a seat surface of a seat device can be transferred about a backrest axis from a folded-up seat surface position into a folded-down seat surface position. For this purpose, the seat surface is connected to the associated backrest with a folding device that forms a backrest axis that runs essentially horizontally. In the raised seat surface position, the seat surface is generally vertical, whereas in the lowered seat surface position, the seat surface is generally horizontal.

According to the specific embodiment with the first and the second seat device, both seat devices are connected to corresponding flap devices, so that both seat devices have their seat surfaces in a high-ge folded and can be placed in a folded down seat surface position. The first backrest axis formed thereby and the second backrest axis are arranged parallel to one another in the first sitting position and aligned with one another in the second sitting position.

According to a further embodiment, the folding seat device is configured such that the first backrest and the second backrest are aligned essentially parallel to the portal wall when the first seat device and the second seat device are in a use position, in particular in the first seat position or in the second seat position . Correspondingly, a respective seat orientation is aligned in the longitudinal direction.

According to a further embodiment, the portal wall can have a receptacle which is designed to receive, in particular to countersink, the folding seat device. For example, the first seat device and the second seat device can be arranged with one another in such a way, in particular by the overlapping arrangement, that the seat devices can be arranged completely in the receptacle. For example, the receptacle is designed as a compartment-shaped volume in the portal wall, so that the folding seat device can be arranged in it in a protected manner.

Furthermore, the folding seat device and/or the portal wall can be designed such that the folding seat device in the stowed position and/or the portal wall forms a support device for standing passengers or passengers in wheelchairs to lean against. For example, a seat device of the folding seat device that is in a vertical position can have support means, for example a cushion.

A seat surface, in particular the first seat surface and the second seat surface, preferably has a seat width of at least 30 cm, in particular at least 35 cm, preferably at least 40 cm.

According to a further embodiment, the portal wall, the fastening device, the folding seat device, the first seat device, the second seat device and/or the connecting device is/are designed in such a way that the folding seat device, in particular the first seat device and the second seat device, can be connected exclusively via the portal wall in the body are supported. In particular, in addition to the devices mentioned, no further support device(s) and/or carriers for dissipating weight forces into the car body, in particular into the floor of the passenger transport vehicle, are provided.

Furthermore, the portal wall, the fastening device, the folding seat device, the first seat device, the second seat device, and/or the connecting device is/are configured and designed in such a way that, with the aid of the first seat device or with the aid of the second seat device, a payload of at least 100 kg, in particular of at least 120 kg, preferably in particular at least 130 kg, carried and derived in the vehicle body.

The embodiments described above can be combined with one another as desired, but in a sensible manner, with the portal having two portal walls in the direction of the portal, on each of which a folding seat device is provided according to one or more of the exemplary embodiments described above.

exemplary embodiments

1 shows a passenger transport vehicle 1 designed as a rail vehicle. In particular, the rail vehicle is designed as a tram. According to the present exemplary embodiment, this comprises a plurality of car bodies 10 connected to one another by articulation devices 11, with each unsupported car body being equipped with a door device 12.

2 represents two such car bodies 10 of the passenger transport vehicle 1 according to FIG 1 in a highly schematic way.

With respect to a car body 10, a longitudinal direction 2, a transverse direction 3, a vertical direction 4, and a horizontal plane 5 are defined.

In a car body 10 according to 2 a plurality of portals 20 is shown schematically, for example, a portal 20 can be arranged at one end of the car body 10, but also in the area of the door device 12. A portal 20 extends in the transverse direction 3 and thus defines a portal transverse direction 23.

The car bodies 10 of a single passenger transport vehicle 1 are connected in the area of the joints by means of passages. For example, such a passage has a bellows.

3 shows a cross section through the car body 10 according to FIG 1 and 2 and thereby clarifies the subject matter of the present invention in a further manner using a specific exemplary embodiment. In particular, the portal 20 is shown in a plan view, which is arranged on a hinge-side end of the car body 10 . Correspondingly shows 3 a passage from a car body 10 into another car body 10 connected to it.

A portal 20 is composed, like a frame, at least of portal walls 21 arranged on both sides and a portal cap 24 connecting the portal walls 21 and extends essentially in the transverse direction 3 , which coincides with the transverse direction 23 of the portal. An extension of one of the portal walls in FIG. 21 in the transverse direction 23 of the portal is referred to as the portal depth 22 .

In particular, a portal depth 22 of the portal wall 21 in the area for arranging a folding seat device 30 is to be measured.

In the present exemplary embodiment, the folding seat device 30 has, but is not limited to, a first seat device 40 and a second seat device 50 . The folding seat device 30 is fastened to the portal wall 21 with the aid of a flexible fastening device 25 in such a way that the folding seat device 30 with the first seat device 40 and with the second seat device 50 can assume a stowed position on the one hand and at least one use position on the other. In 3 For example, the stowed position is represented by a broken line of the first seat device 40 and the second seat device 50, and a use position of the first seat device 40 and the second seat device 50 is represented by solid lines.

In the further detailed description of the present embodiment is also on the 4 until 6 referenced.

The folding seat device 30 with the first seat device 40 and the second seat device 50 is flexibly fastened to the portal wall 21 with the aid of a fastening device 25 . The fastening device 25 is designed in such a way that it forms a pivot axis 26 running in the longitudinal direction 2 . When the folding seat assembly 30 is removed from the stowed position ( 4 ) into a first seating position (usage position, 5 ) is moved, the folding seat device 30 pivots about the pivot axis 26.

The storage position of the folding seat device 30 is using the 4 described. The folding seat device 30 is located essentially completely countersunk in a receptacle 29 of the portal wall 21. The receptacle 29 is designed as a support device 28 forming a backrest, which can be used to lean on or support standing passengers. A region of the floor 13 immediately adjacent to the portal wall 21 serves as a standing area for passengers.

In 4 Illustrated by a broken line is an additional standing area 7 for passengers that is available when the folding seat assembly 30 is in the stowed position.

the 5 and 6 each show a use position of the folding seat device 30, in particular shows 5 a first seating position, and 6 a second seating position of the folding seat device 30.

In 3 the additional style area 7 is smaller, in particular about 50% smaller, than the additional style area 7 in 4 , since the folding seat device 30 in the first seating position partially uses the larger ( 4 ) additional standing area 7 in the vertical direction 4 covered.

The fact that the additional standing area 7 from 4 and 5 in 6 it is not shown that such an additional standing area 7 is not available when the folding seat device 30 is in the second seating position. This is because the folding seat device 30 is arranged essentially completely above the additional standing area 7 in the vertical direction 4 .

With the help of 5 and 6 , the folding seat assembly 30 will be described with respect to a specific embodiment of the first seat assembly 40 and the second seat assembly 50 .

The first seat device 40 is composed of at least a first seat surface 41, a first backrest 43 and a first folding device forming a first backrest axis 44. The first seat surface 41 can be moved by pivoting about the first backrest axis 54 from a folded-in position extending in the vertical direction 4 into an unfolded position extending parallel to the horizontal plane 5 .

The second seat device 50 has at least one second seat surface, a second backrest 53 and a second folding device forming a second backrest axis 54 . The second seat surface 51 can also variably adopt a folded-in position (aligned in the vertical direction 4) and an unfolded position (parallel to the horizontal plane 5) by pivoting the second seat surface 51 about the second backrest axis 54.

In order to move the seat device 30 from the stowed position into the first seated position, after the folding seat device has been pivoted about the pivot axis 26, the first seat surface 41 and the second seat surface 51 are each brought into the unfolded position. Starting from the stowed position, the first backrest 43 and the second backrest 53 are parallel to one another and overlap in the longitudinal direction 2. The first seat position thus means that the first seat device 40 and the second seat device 50 are arranged back to back to one another. Correspondingly, in the first seating position, a first seat orientation 42 of the first seat device 40 is oriented opposite to a second seat orientation 52 of the second seat device 40 . In the first seating position, the folding seat device 30 - due to the back-to-back arrangement of the first seat assembly 40 and the second seat assembly 50 - protrudes only so far into an interior space 19 of the vehicle body 10, so that a reduced additional standing area 7 for standing passengers next to the Folding seat device 30 is available in the first seating position. In particular, a distance between the folding seat device 30 and a vehicle center 18 in the transverse direction 4 is at least equal to a width of the first seat device 40 or the second seat device 50.

If now the folding seat device 30 from the first seat position ( 5 ) to the second seating position ( 6 ) are moved, a connecting device 32 comes into play, which connects the first seat device 40 to the second seat device 50 . The connecting device 32 forms a pivot axis 31 running in the vertical direction 4 about which the second seat device 50 can be pivoted about the first seat device 40 . The second seat position of the folding seat device 30 is realized by pivoting the second seat device 50 from the back-to-back arrangement according to the first seat position into a parallel arrangement next to the first seat device 40 . In this case, the first seat alignment 42 is aligned parallel to the second seat alignment 52 .

In order to increase the safety of passengers, the first seat position and the second seat position can each be firmly assumed with the aid of a locking device 33 . For this purpose, the locking device 33 is designed in such a way that it can temporarily fix both the first seat device 40 and the second seat device 50 together in the first seat position and in the second seat position.

The second seating position is also in 3 shown using the solid lines of the first seat assembly 40 and the second seat assembly 50 . It is clear here that the folding seat device 30 in the second seating position, in particular at its maximum, projects into the interior 19 in the transverse direction 3 or in the transverse direction 23 of the portal up to a center 18 of the vehicle.

In addition or as an alternative to the details of the previous exemplary embodiment, but based on it, a process for moving the folding seat device 30 from the stowed position to the first seating position and then to the second seating position is explained below:

In a first step, the folding seat device 30 is folded about the pivot axis 26, if present, out of the receptacle 29 by approximately 180°. In the stowed position, the first seat surface 41, the second seat surface 51, the first backrest 43 and the second backrest 53 are arranged parallel, perpendicular to the transverse direction 23 of the portal and overlap one another.

A space requirement of the folding seat device 30 is defined in the stowed position essentially by a width and depth of a seat surface 41, 51, and the addition of the thicknesses or strengths of the seat surfaces 41, 51 and the backrests 43, 53. For the sake of clarity, it is stated that this space requirement corresponds to a stacked package of the seat surfaces 41, 51 and the backrests 43, 53.

If the first seating position is to be assumed, the first seat surface 41 is folded down from the first backrest 43 and the second seat surface 51 is folded down from the second backrest 53.

In order to move from the first seated position to the second seated position in an additional step, the locking device 33 can be opened—if present—so that the second seat device 50 is pivoted by approximately 180° about the pivoting axis 31 . If necessary, the seat devices 40, 50 are now to be connected to one another using the locking device 33.

Additionally or alternatively, it is conceivable to move the folding seat device 30 directly from the stowed position into the second seating position. For this purpose, the second seat device 50 is pivoted about the pivot axis 31 immediately after pivoting about the pivot axis 26 . A folding down of the seat surfaces 41, 51 then takes place.

Although specific embodiments have been illustrated and described herein, it is within the scope of the present invention to illustrate appropriate intermediate solutions and/or to appropriately modify the embodiments shown without departing from the scope of the present invention. This is because, for example, the folding seat device 30 can also be arranged on the portal wall 21 with the aid of the fastening device 25 in such a way that the folding seat device 30 does not completely protrude beyond the portal wall 21 in the transverse direction 23 of the portal when in a use position, but instead the first seat device 40 is provided in the region of the portal wall 21 , and, at least partially, the second seat device 50 projects beyond the portal depth 22 into the interior 19 of the vehicle body 10 .
