In a bus in which a rear entrance/exit is provided in the rear part of the cabin behind the rear axle as in Patent Document 1, even if there are many passengers and it is difficult to move forward from the rear part of the cabin, passengers can get on and off in the rear. Since it is possible to get on and off from the entrance, convenience is enhanced, but the number of seats in the rear part of the compartment is reduced because a passage for getting on and off from the rear entrance / exit must be secured in the rear part of the compartment.

The congestion situation (number of passengers) inside the bus of a route bus differs depending on the route and time of day, etc., and whether to give priority to the convenience of the rear entrance or the number of seats in the rear of the passenger compartment depends on the congestion situation inside the bus. change accordingly. For example, in a situation where there are few passengers and it is easy to move forward from the rear of the passenger compartment, it is possible to prioritize the number of seats over the convenience of the rear entrance and exit, and increase the number of seats by not using the rear entrance and exit and always closing it. preferable. Conversely, in situations where there are many passengers and it is difficult to move forward from the rear of the passenger compartment, priority should be given to the convenience of the rear entrance/exit over the number of seats, and the number of seats should be reduced and the rear entrance/exit should be used (opened/closed). is preferred.

Therefore, the present disclosure is a bus capable of changing the number of seats that can be seated according to whether or not the rear entrance/exit is used, and allowing smooth boarding/alighting from the rear entrance/exit when the rear entrance/exit is used. The purpose is to provide a rear structure for

In order to achieve the above object, the bus rear structure of the present disclosure includes a rear entrance/exit, a rear floor surface, and a specific seat.

The specific seat is arranged at a position where the seat portion in the sitting position covers a part of the floor surface of the rear aisle from above, and the seat portion in the stowed position is out of the floor surface of the rear aisle.

When the above-configured bus is used as a route bus, for example, and the bus is operated in a manner that uses the rear entrance (a manner in which the rear entrance is opened and closed by the rear door), the seat portion of the specific seat is set to the retracted position. Since the seat portion in the retracted position stands up and is removed from above the floor surface of the rear boarding/alighting aisle, the specific seat does not become an obstacle when the passenger moves in the rear boarding/alighting aisle, allowing the passenger to smoothly board/alight from the rear boarding/alighting opening. be able to. In addition, passengers can use the rear boarding and alighting passage as a space to board the vehicle while standing (standing space), thereby alleviating congestion in the vehicle.

When operating in a manner in which the rear entrance/exit is not used (a manner in which the rear entrance/exit is always closed by the rear door), the seat portion of the specific seat is set to the seating position. The seat portion of the seated position reclines from the retracted position and overlaps a part of the floor surface of the aisle from above, so that the passenger can sit on the seat portion of the specific seat. Therefore, the rear passenger aisle can be effectively used as a seating space for passengers, and the number of seats that can be seated can be increased compared to when the rear passenger door is used.

According to the present disclosure, it is possible to change the number of seats that can be seated depending on whether or not the rear entrance/exit is used, and to enable smooth boarding/alighting from the rear entrance/exit when the rear entrance/exit is used. can be done.
