An aircraft divan includes a lateral bracket connecting between front and rear legs with lateral bracket front and rear ends, a first track defined by the lateral bracket between the lateral bracket front and rear ends, an upright, having upright top and bottom ends, a second track defined by the upright between the upright top and bottom ends, a seat pan having seat pan front and rear ends, the seat pan being slidingly connected to the first track adjacent to the seat pan rear end, and a backrest having backrest top and bottom ends, the backrest being slidingly connected to the second track adjacent to the backrest top end. The seat pan rear end is pivotably connected to the backrest adjacent to the backrest bottom end such that movement of the seat pan is transmitted to the backrest so as to move together between upright and berth positions.

In various embodiments, a drive system with a motor rotary actuator driven linkage and an override system is provided. The override system may be a manually actuated override system that, in response to a power loss or outage, is configured to disengage one or more links of drive system 100 from the electric motor rotary actuator, allowing the disengaged link to be moved and/or repositioned. Moreover, drive system 100 and, more specifically, the override system may be configured to restore normal operation to the disengaged link in response to power being restored (i.e., by reengaging the link).

Purpose is to enable communication with a vehicle installation installed in a vehicle in a manner that facilitates implementation of a security measure and with high sensitivity and at low cost. An in-vehicle communication system includes an interior light with communication function, a seat and a display device, the interior light with communication function including a LED configured to transmit information to the seat and the display device via visible light communication, and the seat and the display device including light receiving units configured to receive information transmitted from the interior light with communication function and control units configured to control themselves based on the information received by the light receiving units.

A double-track vehicle, comprising upper and lower carriages, which are respectively a passenger carriage (1) for providing passenger seats and a cargo carriage (2) for placing cargo, the passenger carriage (1) and the cargo carriage (2) being respectively provided with a passenger door (3) for passengers to get on and off and a cargo door (4) for loading and unloading cargo. The vehicle carries out simultaneous transport of passengers and cargo, allowing for the function of the rail vehicle to no longer be singular and largely reducing transport and maintenance costs. At the same time, passenger transport and cargo transport are divided into two layers, which completely separates cargo transport and passenger transport, thereby providing passengers with a comfortable seating environment and improving seating safety.
