INTERIOR STRUCTURE OF A MASS TRANSIT VEHICLE

摘要

A public transit vehicle has a vehicle body having a roof defining an interior ceiling surface, two side walls each extending longitudinally of th e vehicle including an upper side wall portion connecting to the roof and a row of windows underneath the upper portion, a central aisle and two rows of seats each on a respective side of the aisle and along the side wall at the windows. Stanchions for supporting passengers while standing are shaped so that they curve upwardly and outwardly of the aisle to a wider spacing at the ceiling than at the seats. Between two stanchion mounting rails is provided a central ceiling panel dropped fro m the roof to define an air supply duct longitudinally along the aisle above the passengers. This is supplied with ventilation air by a roof mounted system and communicates by individual sub-ducts with a series of fans in the side walls. A flap valve a t the fan can be operated to cause heated air when required to be supplied through the main side wall posts to bottom discharge openings at the bottom interior panels o r to cause cooled air to be supplied to a duct along the top of the windows.
