The seat of said second kind bridges space between the secondary partition wall member and the cabin floor.

## Background
FIELD OF THE INVENTION
The present invention relates to a class divider for a passenger vehicle. More particularly but not exclusively it relates to class divider for at least partially dividing areas having different classes of seats in a passenger vehicle.
BACKGROUND OF THE INVENTION
Currently class dividers that exist between different classes of aircraft seat regions within an aircraft are substantially planar panels. They may be fabricated from a composite panel material and are provided with aluminium trim to facilitate the fastening of the panel to parts of the aircraft. Usually such panels are planar and their normal extends substantially parallel to the longitudinal direction of the plane. However aircraft seats in certain aircraft and in certain classes are no longer positioned in orthogonal directions relative to the aircraft body, but at angled directions. This can result in valuable space within in an aircraft not being utilised between such seats and any class dividers that may be adjacent to such seats. Furthermore where passenger space is desired to be increased, parts of the plane where in-flight entertainment features can be provided may also be restricted. Such components can also generate significant heat that needs to be easily dissipated and hence it may be undesirable to place such components in confined spaces.
It is an object of the present invention to provide a class divider that can offer improved space utilisation and/or at least partially ameliorates some of the abovementioned disadvantages or which at least provides the public with a useful choice.

DETAILED DESCRIPTION OF THE INVENTION
With reference to the above drawings, in which similar features are generally indicated by similar numerals, a class divider according to a first aspect of the invention is generally indicated by the numeral 100.
In one embodiment now described, there is provided a class divider 100 for dividing adjacent seating areas of a passenger vehicle having different types of seats or seating arrangements. The class divider 100 comprises a first wall member 110 located towards the front of the vehicle such as an aircraft, and a second wall member 120 located rearwardly of the first wall member 110. Both the first wall member 110 and the second wall member 120 are made of plastic in a moulding or forming process. Such may include a blow moulding, injection moulding, or any other similar suitable moulding process. The first wall member and the second wall member are secured or securable to each other each other by means of securing fasteners 130. It is envisaged that at least one or both of the first wall member and the second wall member will be relatively thick, to be able to offer a reasonable amount of rigidity to the class divider 100 to structurally support it.
However, in a preferred embodiment, the class divider 100 can also include a support frame 140 that extends between the first wall member 110 and the second wall member 120 to hold them together, support them, and to provide rigidity to the class divider 100.
In one embodiment it is envisaged that the securing fasteners 130 can be integrally moulded formations (not shown) moulded into one or both of the first wall member 110 and the second wall member 120. Alternately they could be snap fit-, clip fit-, screw fit-, threaded-, or bayonet-type formations.
The preferred embodiment of the class divider will follow the contours of part of the seating arrangement in front of it, to help ensure that no redundant space is exists between the seating arrangement 501a&b in front and the dividers.
In the embodiments shown in the figures, two versions of the class divider 100 are envisaged. One version of the divider arrangement, the inboard class divider 100a as shown in FIGS. 14-24 will surround and follow the contours of the rear of an inboard seating arrangement 501a disposed towards the inboard of the aircraft, while the other version of the divider arrangement, the outboard class divider 100b as shown in FIGS. 1-13, will follow the contours of the rear of an outboard seating arrangement 501b disposed towards the outboard of a passenger vehicle. Both versions may cooperate and be positioned adjacent each other as shown in FIG. 12b there together they define a substantial partition between two classes of the aircraft.
In one preferred embodiment as shown in the figures, the first wall member 110 and second wall member 120 of the class dividers 100a&b define complementary concave and convex wall shapes respectively when viewed from the top as they extend around the contours of their respective seating arrangements 501a&b. The first wall member 110 is mounted forward of the second wall member 120, with the first wall member defining a concave forward facing curve when viewed from above, and the second wall member defines a convex forward facing curve when viewed from the rear. In this way, the first wall member 110 and second wall member 120 have complementary nesting concave and convex shapes respectively.
However it is envisaged that in an alternative embodiment, the shape of the first wall member 110 and/or the second wall member 120 could include concave formations, as well as any other three dimensional complex curves in order to follow non-linear contours of an adjacent seating arrangement disposed in front of it (i.e. in an advanced more location in a vehicle).
The first wall member 110 and second wall members 120 enclose a cavity 150 between them. This cavity may also be continued by parts of the seat located in a contiguous manner adjacent the divider.
As seen in FIG. 15 a lower edge 139 of the first wall member is preferably contoured to create an interface with the seat (not shown) in front. The seat in front fills the gap between the first wall member and the cabin floor. This means that the first wall member does not need to be of the same vertical extent as the second wall member, thereby reducing weight of the partition.
The cavity can be used for the installation of cabling for power and In flight Entertainment (IFE) services.
The cavity is preferably open above the location where the IFE screen or monitor is located to allow heat created thereby to rise up through the cavity and exit through its opening into for example ambient conditions above the divider. Other associated electric or electronic components may also have the heat generated thereby dissipated in a similar manner.
The class divider further includes a plinth formation 160 on which one or more of the first wall member 110, the second wall member 120 and the support frame 140 are directly or indirectly mounted or mountable. The plinth formation 160 provides a stable base for the mounting of the first wall member 110, the second wall member 120 and the support frame 140. The purpose of the plinth is structural, specifically to provide lower mounting locations for units, where the aircraft does not have mounting tracks. The plinth spreads the load from the tracks into the units above, and allows them to be positioned wherever required, instead of having to be mounted directly above a pre-existing track location.
In a preferred embodiment, the plinth formation 160 includes seat track attachment formations 170 for attaching the class divider 100 to tracks on the floor (not shown) of the aircraft. The attachment formations 170 can be used to attach the class divider to the same seat tracks that the adjacent seats or seating arrangements 500 a&b are attached to, thereby negating the requirement of providing additional track formations (and additional weight).
The plinth formation further includes a pedestal formation 165 suitable for mounting of a monitor and/or a tray table arrangement, as shown in FIG. 1. It is also envisaged that a pedestal formation 165 could be mounted independently in association with the class divider 100.
The pedestal formation 165 is associated with the aisle seat located behind the class divider 100. The pedestal formation 165 is located adjacent the aisle allowing access by a passenger to an aisle seat disposed behind the class divider 100. The pedestal formation 165 is also located adjacent to the headstrike zone for the seat or seating arrangement that the pedestal formation 165 is associated with.
A tray table arrangement 270 as well as a video monitor 230 and other in-flight entertainment controls and accessories is mounted or mountable on the pedestal formation for presentation to a passenger.
The class divider 100 further includes bin rail attachment formations 180 for attaching the class divider 100 to bin rails (not shown) of an aircraft, or any other high level mounting rails found in an aircraft, to thereby provide additional rigidity and/or stability to the class divider 100 when installed.
In addition, it is envisaged that the class divider 100 can also include a floor proximity light fitting 190 for providing floor proximity lighting for guiding passengers along an aisle alongside the class divider 100. The class divider also can include an in-use light fitting 195 for providing an indication that something onboard the aircraft is in use.
Typically in large aircraft, channels (not shown) run underneath the flooring, through which information and power cabling (not shown) can be routed for distribution throughout the aircraft.
The class divider further includes support formations 210 suitable for supporting a bassinet, in another embodiment can include a bassinet (not shown) itself. In a preferred embodiment, the bassinet is removably attachable to one or more of the first wall member 110 and the second wall member 120.
Preferably, the bassinet is pivotally coupleable to one or more of the first wall member, the second wall member, and the support frame in a removable manner, to move between a stowed position in which it is stowed out of the way of passengers seated behind the class divider 100, and a folded out position in which it is capable of supporting a sleeping infant. It is envisaged that the bassinet will be preferably supported by the support frame, or by a thickened first or second wall member adapted and configured to be capable of supporting the additional weight of an infant.
In a preferred embodiment, the class divider 100 defines one or more apertures 220 (as shown in FIG. 14 for the inboard arrangement) or recesses 222 (as shown in FIG. 1 for the outboard arrangement), suitable for receiving at least part of the legs (not shown) of a passenger (not shown) seated in an adjacent seating arrangement 500 disposed behind the class divider 100, to allow a passengers legs to be at least partially extended underneath the seating arrangement 501 in front of the class divider 100. The aperture 220 could also be a recess (not shown), or a cut-out (not shown). It is envisaged that where the seats or seating arrangements 500 behind the class divider are arranged in a staggered or offset formation, then the aperture 220, will be aperture will be disposed in an offset fashion towards one side of the class divider 100.
Another feature included on the rear side of the class divider 100 is a video monitor 230 for passenger entertainment and information. It is envisaged that the monitor will preferably be as thin as possible, and will include one of a Liquid Crystal display (LCD) screen; a plasma screen monitor screen, an Organic Light Emitting Diode (OLED) screen, or a three dimensional display screen. In a preferred embodiment, the monitor will be mounted to a pivotally moveable bracket (not shown) that will allow it to be moved out of a recess 240 in the first wall member 110 or second wall member 120 and pivoted about at least two axes of rotation for optimum convenience of viewing by a passenger. The monitor may alternatively be mounted in a manner to remain static.
The class divider 100 also includes an electrical supply socket 250 for supplying power to portable electronic device, and for charging of such devices, and a data connection socket 260 such as a Universal Serial Bus (USB) socket for allowing such devices to be networked with each other, to the In flight entertainment system (for example for playing music through the seat speakers), or with the Internet via an Internet portal located elsewhere on the aircraft. Preferably, the electrical power supply socket 250 is adapted and configured for supplying one or both of DC voltage and AC voltage.
Further, the class divider includes a tray table arrangement 270. The tray table arrangement includes a pair of tray members 272 moveable by virtue of a tray table support mechanism 280. Each tray member 272 defines a pair of opposed major faces 274.
The tray member 272 are moveable between a deployed position, in which at least one or both of the tray members 272 are usable by a passenger in seat 500 as a support for items, and a stowed position in which the tray table 270 is stowed in a position less intrusive to a passenger.
