Passenger seat fixation for a vehicle

Description

BACKGROUND OF THE INVENTION

[0001] The invention relates to a wagon body of a vehicle, in particular a rail vehicle, according to the preamble of claim 1 and comprising a passenger compartment with a compartment floor and a seat fixation device located within the passenger compartment. The passenger compartment defines a longitudinal direction, a transverse direction and a height direction, a centerline plane, a first compartment side and a second compartment side. The centerline plane runs parallel to the longitudinal direction and the height direction, wherein the first and second compartment side are located at opposite sides of the centerline plane. The seat fixation device comprises a first seat fixation unit and a second seat fixation unit located at the compartment floor, the first seat fixation unit being located at the first compartment side at a first distance from the centerline plane and the second seat fixation unit being located at the second compartment side at a second distance from the centerline plane.

[0002] In public transportation, in particular in regional and commuter traffic, train set operators typically desire to achieve and use the maximum transport capacity of the train set in order to be as cost effective as possible. However, the attractiveness of train lines to passengers may reach its limits or even decline due to the passengers' perception of a lack in passenger comfort if train sets are always operated under their maximum seating capacity. This may lead to a situation where potential passengers may choose other perceivably more comfortable means of transportation. A situation which is, obviously, not in the interest of train set operators.

[0003] Thus, from the point of view of a train set operator there is a need for high flexibility in the internal equipment of their rolling stock allowing rapid reactions to changes in passenger comfort preferences, eventually even between different lines (e.g. a local commuter line with higher station frequencies and a regional line with lower station frequencies) operated at a time.

[0004] Conventional wagon bodies as they are known, for example, from WO 98/09860 A1 typically show a seat fixation design with first and second seat fixation units located at the compartment floor at equal distance from the centerline plane. Typically, a so called 2+2 seat arrangement (per row) is chosen with two seats on each vehicle side. The first and second seat fixation units each either support a seat post located at the inner side of the inner seat (i.e. at the central corridor) or located between the two seats supported. Both configurations allow rather limited flexibility in terms of different seat arrangements at low expense.

[0005] A generic wagon body with asymmetric seat fixation design and a so called 2+3 seat arrangement (per row) is known from US 2008/0315036 A1 (corresponding to the preamble of claim 1).

SUMMARY OF THE INVENTION

[0006] It is thus an object of the invention to, at least to some extent, overcome the above disadvantages and to provide a wagon body that allows a more flexible passenger seat arrangement at low expense.

[0007] This and other objects are achieved according to the present invention (as defined by the technical features set forth in claim 1) which is based on the technical teaching that a more flexible passenger seat arrangement at low expense is achieved using an arrangement of the first and second seat fixation units that is noticeably asymmetric with respect to the centerline plane. Such a noticeably asymmetric arrangement allows achieving a more flexible seat arrangement. More precisely, thanks to the noticeably asymmetric arrangement of the first and second seat fixation units, a basic 2+2 seat configuration (per row) can easily be upgraded or modified into a 2+3 seat configuration or even a 2+1 seat configuration, if necessary, without the necessity to modify the seat support structure (such as e.g. vertical support struts or the like).

[0008] Hence, the seat configuration may be easily adapted to the specific needs of the line to be operated in order to offer an optimized number of seats (adapted or tailored to the number of passengers to be expected on this line), the seats in turn being adapted to provide the maximum amount of comfort for the respective configuration. Thus, for example, in a 2+1 seat configuration (i.e. a situation with a comparatively low number of passengers to be expected) very wide seats may be used noticeably enhancing passenger comfort and, thus, the attractiveness of the line. On the other hand, e.g. during peak travel periods, a 2+3 seat configuration may be chosen to provide a maximum of seats for the passengers to be expected.

[0009] Thus, the present invention relates to a wagon body of a vehicle, in particular a rail vehicle, in accordance with claim 1 and comprising a passenger compartment with a compartment floor and a seat fixation device located within the passenger compartment. The passenger compartment defines a longitudinal direction, a transverse direction and a height direction, a centerline plane, a first compartment side and a second compartment side, the centerline plane running parallel to the longitudinal direction and the height direction, the first and second compartment side being located at opposite sides of the centerline plane. The seat fixation device comprises a first seat fixation unit and a second seat fixation unit located at the compartment floor, the first seat fixation unit being located at the first compartment side at a first distance from the centerline plane and the second seat fixation unit being located at the second compartment side at a second distance from the centerline plane. To achieve the noticeably asymmetric arrangement of the first and second seat fixation unit, the second distance ranges from 125% to 225% of the first distance, in particular from 150% to 225% of the first distance, preferably from 175% to 200% of the first distance.

[0010] Depending on the overall dimensions of the wagon body, the first and second distance may have any suitable amount. However, with preferred embodiments of the invention showing advantageous dimensions providing high transport capacity, the first distance ranges from 250 mm to 550 mm, in particular from 300 mm to 500 mm, preferably from 350 mm to 450 mm. In addition or as an alternative, the second distance ranges from 600 mm to 900 mm, in particular from 650 mm to 850 mm, preferably from 700 mm to 800 mm.

[0011] The seat fixation device may be of any suitable design adapted to provide fixation of a seat unit (at each compartment side) comprising one or more passenger seats.

[0012] However, according to the invention, thanks to simple and reliable fixation properties, a conventional arrangement is chosen, wherein the seat fixation device comprises a third seat fixation unit associated to the first seat fixation unit, and the seat fixation device comprises a fourth seat fixation unit associated to the second seat fixation unit. The third seat fixation unit is located in the region of a first side wall of the compartment on the first compartment side, in particular, located at the first side wall, the third seat fixation unit, in the transverse direction, having a third distance from the first seat fixation unit. The fourth seat fixation unit is located in the region of a second side wall of the compartment on the second compartment side, in particular, located at the second side wall, the fourth seat fixation unit, in the transverse direction, having a fourth distance from the second seat fixation unit.

[0013] The first distance and the second distance are selected as a function of an individual seat width (i.e. the individual seat's dimension in the transverse direction) of an individual passenger seat to be mounted is a single seat unit, to be used by a single passenger and to be supported via the second seat fixation unit and the fourth seat fixation unit, the first distance and the second distance being selected such that the third distance ranges from 120% to 160% of the individual seat width, in particular from 130% to 150% of the individual seat width, preferably from 135% to 145% of the individual seat width. By this means it is possible to achieve a configuration where the first and third support unit are adapted to properly support a wide range of different seat units (e.g. a seat unit with two "normal" seats for a conventional 2+2 seat configuration, a seat unit with two "wide" seats for a 1+2 seat configuration, or a seat unit with three "narrow" seats for a 2+3 seat configuration etc).

[0014] In addition or as an alternative, the first distance and the second distance are selected such that the fourth distance ranges from 70% to 110% of the individual seat width, in particular from 80% to 100% of the individual seat width, preferably from 85% to 95% of the individual seat width. By this means it is possible to achieve a configuration where the second and fourth support unit are adapted to a wide range of different seat units (e.g. a seat unit with two "normal" seats for a conventional 2+2 seat configuration, a seat unit with one "wide" seat for a 1+2 seat configuration, or a seat unit with two "narrow" seats for a 2+3 seat configuration etc).

[0015] Again, depending on the overall dimensions of the wagon body, the individual seat width may have any suitable amount. However, with preferred embodiments of the invention showing advantageous dimensions providing high transport capacity at an appropriate level of passenger comfort, the individual seat width ranges from 520 mm to 720 mm, in particular from 580 mm to 690 mm, preferably from 620 mm to 670 mm.

[0016] The seat fixation device may be of any suitable design providing proper fixation of the respective seat units. With preferred embodiments of the wagon body according to invention showing a high flexibility in the seat row pitch (i.e. seat distance in the longitudinal direction of the vehicle), the first seat fixation unit comprises a first seat fixation rail at the compartment floor, in particular within the compartment floor, and/or the second seat fixation unit comprises a second seat fixation rail at the compartment floor, in particular within the compartment floor.

[0017] Furthermore, with preferred embodiments of the invention having a particularly simple and robust design, the seat fixation device comprises a first seat fixation post associated to the first seat fixation unit and extending in the height direction and/or the seat fixation device comprises a second seat fixation post associated to the second seat fixation unit and extending in the height direction. Such seat fixation posts provide a simple and robust support interface to the respective seat units to be installed.

[0018] Mounting on the seat units is further simplified and flexibility in the seat row pitch is enhanced as the seat fixation device comprises a third seat fixation unit associated to the first seat fixation unit, the third seat fixation unit comprising a third seat fixation rail located in the region of, preferably at a first side wall of the compartment on the first compartment side. The same applies r as, in addition, the seat fixation device comprises a fourth seat fixation unit associated to the second seat fixation unit, the fourth seat fixation unit comprising a fourth seat fixation rail located in the region of, preferably at a second side wall of the compartment on the second compartment side.

[0019] With preferred embodiments of the invention, a 2+3 seat configuration is realized, wherein a first seat unit is mounted via the first seat fixation unit and a second seat unit is mounted via the second seat fixation unit; the first seat unit comprising three passenger seats and the second seat unit comprising two passenger seats. Preferably, each of the passenger seats has a seat width, in the transverse direction, ranging from 445 mm to 455 mm.

[0020] With other preferred embodiments of the invention a 2+2 seat configuration is realized, wherein a first seat unit is mounted via the first seat fixation unit and a second seat unit is mounted via the second seat fixation unit, the first seat unit and the second seat unit comprising two passenger seats. Preferably, each of the passenger seats has a seat width, in the transverse direction, ranging from 480 mm to 520 mm.

[0021] With further preferred embodiments of the invention a 1+2 seat configuration is realized, wherein a first seat unit is mounted via the first seat fixation unit and a second seat unit is mounted via the second seat fixation unit, the first seat unit comprising two passenger seats and the second seat unit comprising one passenger seat. Preferably, each of the passenger seats has a seat width, in the transverse direction, ranging from 630 mm to 680 mm.

[0022] It will be appreciated that the present invention may be used in the context of any type of vehicle. For example it may be used in the context of single deck vehicles. Preferably, the present invention is used in the context of double-deck vehicles since, here, its advantages may be particularly effective. It will be further appreciated that the arrangement of the seat fixation device according to the invention may be provided in either one or both of the decks of the double deck vehicle.

[0023] For example, one of the decks (e.g. the upper deck) may be provided with another seat configuration than the other deck (e.g. the lower deck). Thus, for example, the upper deck may be (initially) designed as a first-class area with a 1+2 seat configuration, while the lower deck may be (initially) provided with a conventional 2+2 seat configuration. However, thanks to the flexibility of the seating arrangement provided with the invention, the seat arrangement on the respective deck may be easily adapted to be actual needs of the respective line to be operated.

[0024] The present invention further relates to a vehicle, in particular a rail vehicle, with a wagon body according to the invention.

[0025] Further embodiments of the invention will become apparent from the dependent claims and the following description of preferred embodiments which refers to the appended figures, the scope of the invention being defined by the appended claims.

DETAILED DESCRIPTION OF THE INVENTION

[0027] In the following, a preferred embodiment of vehicle according to the invention in the form of a double deck rail vehicle 101 will be described with reference to Figure 1 to 3. In order to simplify the explanations given below, an xyz-coordinate system has been introduced into the Figures, wherein (on a straight, level track) the x-axis designates the longitudinal direction of the vehicle 101, the y-axis designates the transverse direction of the vehicle 101 and the z-axis designates the height direction of the vehicle 102.

[0028] The vehicle 101 comprises a wagon body 102 with an upper deck compartment 103 and a lower deck compartment 104. Both decks 103, 104 are equipped with passenger seating in a 2+3 seat configuration (per row) as it is suitable for operation on a commuter line with high station frequency for a large number of passengers as will be explained in the following with reference to the upper deck 103.

[0029] The upper deck 103 comprises a first seat unit 105 located at a first compartment side 103.1 of a centerline plane 102.1 of the wagon body 102 and a second seat unit 106 located at a second compartment side 103.2 of the centerline plane 102.1 (the centerline plane 102.1 running parallel to the longitudinal direction and the height direction, i.e. corresponding to the xz-plane).

[0030] The first seat unit 105 comprises three first passenger seats 105.1 with a seat width W1 (i.e. a dimension in the transverse direction y) of about 450 mm combined in a single module mounted to the structure of the wagon body 102. The second seat unit 106 comprises two second passenger seats 106.1 with a seat width W2 = W1 (i.e. a dimension in the transverse direction y) of about 450 mm also combined in a single module mounted to the structure of the wagon body 102.

[0031] Fixation of the first seat unit 105 and the second seat unit 106 is provided via a seat fixation device 107 comprising first to fourth seat fixation units 107.1 to 107.4. More precisely, the first seat unit 105 is mounted via the first seat fixation unit 107.1 and the associated third seat fixation unit 107.3 while the second seat unit 106 is mounted via the second seat fixation unit 107.2 and the associated fourth seat fixation unit 107.4.

[0032] In the embodiment shown, the first to fourth seat fixation units comprise seat fixation rails 107.1 to 107.4 integrated within the floor structure 103.3 of the upper deck compartment 103 (rails 107.1 and 107.2, not shown in greater detail) and compartment side walls (103.4, 103.5) of the structure of the wagon body 102 (rails 107.3 and 107.4), respectively. Such seat fixation rails are beneficial in terms of allowing modification of the seat pitch. However, it will be appreciated that, with other embodiments of the invention, any other seat fixation concept (eventually not allowing such easy modification of the seat pitch) may be chosen.

[0033] In the transverse direction (y direction), the centerline of the first seat fixation rail 107.1 defines a first seat fixation location which has a first distance D1 = 400 mm from the centerline plane 102.1 while the second seat fixation rail 107.2 defines a second seat fixation location which has a second distance D2 = 750 mm from the centerline plane 102.1. Thus, the second distance D2 is 187.5% of the first distance D1 such that a noticeably asymmetric arrangement (in the transverse direction) of the first seat fixation rail 107.1 and the second seat fixation rail 107.2 is achieved. This noticeably asymmetric arrangement is beneficial in terms of enhancing the flexibility of the seat configuration as will be explained further below with reference to Figures 1 to 3.

[0034] The first seat unit 105 is supported via a simple first seat fixation post 107.5 of the first seat fixation unit 107.1, the first seat fixation post 107.5 generally extending in the height direction (z-direction) and mounted at its ends to the first seat unit 105 and the seat fixation rail 107.1, respectively. The second seat unit 106 is supported via a simple second seat fixation post 107.6 of the second seat fixation unit 107.2, the second seat fixation post 107.5 generally extending in the height direction (z-direction) and mounted at its ends to the first seat unit 105 and the second seat fixation rail 107.2, respectively.

[0035] As can be seen from Figure 1, the first seat fixation post 107.5 and the second seat fixation post 107.6 both are designed as comparatively narrow posts having a plane of main extension mainly extending in the height direction (z-direction) of the vehicle 101 in a manner generally parallel to the centerline plane 102.1. However, it will be appreciated that, with other embodiments of the invention, these first and second seat fixation posts do not necessarily have to be arranged substantially parallel to the centerline plane 102.1. More precisely, any other arrangement with an inclination of the plane of main extension of the respective seat fixation post with respect to the centerline plane 102.1 may be chosen as well. Furthermore, any other shape of the respective first and second seat fixation post (in the sectional plane of Figure 1) such as, for example, an arbitrarily curved and/or a generally triangular shape etc may be chosen.

[0036] Figures 2 and 3 show the upper deck 103 of vehicle 101 in different seat configurations, namely a 2+2 seat configuration (per row) in Figure 2 as it is suitable for operation on a regional line with moderate station frequency, and a 1+2 seat configuration (per row) in Figure 3 as it is suitable for operation in a first-class compartment on an intercity line with comparatively low station frequency.

[0037] As can be seen from Figure 2, the only difference with respect to the configuration shown in Figure 1 lies within the fact that a different first seat unit 205 and a different second seat unit 206 are mounted to the otherwise identically configured vehicle 101. The first seat unit 205 comprises two first passenger seats 205.1 with a seat width W3 (i.e. a dimension in the transverse direction y) of about 500 mm combined in a single module mounted to the structure of the wagon body 102. The second seat unit 206 comprises two second passenger seats 206.1 with a seat width W4 = W3 (i.e. a dimension in the transverse direction y) of about 500 mm also combined in a single module mounted to the structure of the wagon body 102.

[0038] As can be seen from Figure 3, the only difference with respect to the configuration shown in Figure 1 lies within the fact that a different first seat unit 305 and a different second seat unit 306 are mounted to the otherwise identically configured vehicle 101. The first seat unit 305 comprises two first passenger seats 305.1 with a seat width W5 (i.e. a dimension in the transverse direction y) of about 650 mm combined in a single module mounted to the structure of the wagon body 102. The second seat unit 306 comprises a single individual second passenger seat 306.1 with an individual seat width W6 = W5 (i.e. a dimension in the transverse direction y) of about 650 mm that is also mounted to the structure of the wagon body 102.

[0039] As can be further seen from Figure 3, the first distance D1 and the second distance D2 are selected such that, in the transverse direction (y-direction), a third distance D3 between the first seat fixation rail 107.1 and the third seat fixation rail 107.3 is about D3 = 940 mm (i.e. about 145% of the individual seat width W6), while a fourth distance D4 between the second seat fixation rail 107.2 and the fourth seat fixation rail 107.4 is about D4 = 580 mm (i.e. about 89% of the individual seat width W6).

[0040] The described selection of the first distance D1 and the third distance D3 has the advantage that any of the first seat units 105, 205 and 305 may be mounted to the vehicle 101 without any modification of the support device 107. The same applies to the described selection of the second distance D2 and the fourth distance D4. Any of the second seat units 106, 206 and 306 may be mounted to the vehicle 101 without any modification of the support device 107.

[0041] In particular, (seen in the transverse direction) comparatively narrow seat units (namely the two seat unit 205.1 and the individual seat unit 306.1) may be mounted as well as comparatively wide seat units (namely the two seat unit 206.1 and the three seat unit 105.1 as well as the two seat unit 205.1) without any modification of the support device 107. Thus, an easy modification of the upper deck compartment 103.1 is possible between a commuter train configuration with a maximum number of passenger seats 105.1, 106.1 (Figure 1), a regional train configuration with a lower number of (wider) passenger seats 205.1, 206.1 (Figure 2) and a first-class intercity train configuration with an even lower number of very wide and high comfort passenger seats 305.1, 306.1 (Figure 3). This greatly increases the flexibility of the vehicle 101 in terms of the seating configuration implemented.

[0042] It will be appreciated that the lower deck compartment 104, in the embodiment shown in Figure 1, has a seat fixation device 108 with a first seat fixation unit in the form of a first seat fixation rail 108.1 and second seat fixation unit in the form of a second seat fixation rail 108.2 of identical design as the first and second seat fixation rail 107.1, 107.2, integrated within the lower deck compartment floor 104.1 in a manner arranged in symmetry with respect to the centerline plane 102.1. However, it will be appreciated that, within other embodiments of the invention, the asymmetric arrangement as described in the context of the seat fixation device 107 of the upper deck compartment may also be realized in addition or exclusively within the lower deck compartment. Moreover, the asymmetric arrangement as described in the context of the seat fixation device 107 may of course also be implemented in a single deck vehicle.

[0043] In the foregoing, the invention has been described in the context of rail vehicles. However, it will be appreciated that the invention may be used in the context of any other type of vehicles used for passenger transport.
