Description

本開示は、バスの後部構造に関する。 The present disclosure relates to rear structures of buses.

特許文献1には、前後の乗降口と客室床面をフロントタイヤハウスより後方に設置する低床式の路線バスが記載されている。また、リアタイヤハウスよりも後方に配置された後の乗降口が図示されている。 Patent Literature 1 describes a low-floor route bus in which front and rear entrances and passenger compartment floors are located behind the front tire house. Moreover, the boarding/alighting opening is shown after being arranged behind the rear tire house.

特開2001-247059号公報JP-A-2001-247059

特許文献1のように後車軸よりも後方の車室後部に後乗降口を設けたバスでは、乗客数が多く車室後部から前方への移動が困難な状況であっても、乗客は後乗降口から乗降することができるため、利便性が高まる一方で、後乗降口から乗降する際の通路を車室後部に確保しなければならないため、車室後部の座席数は減少する。 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.

路線バスの車内の混雑状況(乗客数)は、運行する路線や時間帯等によって相違し、後乗降口の利便性と車室後部の座席数の何れを優先するかは、車内の混雑状況に応じて変わる。例えば、乗客が少なく車室後部から前方へ容易に移動できる状況では、後乗降口の利便性よりも座席数を優先し、後乗降口を使用せずに常時閉止して座席数を増やすことが好ましい。反対に、乗客が多く車室後部から前方への移動が困難な状況では、座席数よりも後乗降口の利便性を優先し、座席数を減らして後乗降口を使用する(開閉する)ことが好ましい。 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.

そこで本開示は、後乗降口の使用時と不使用時とに応じて着座可能な座席数を変更することができ、且つ後乗降口の使用時には後乗降口からの円滑な乗降が可能なバスの後部構造の提供を目的とする。 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

上記目的を達成すべく、本開示のバスの後部構造は、後乗降口と後部床面と特定座席とを備える。後乗降口は、後車軸よりも車両後方の車両側面に設けられ、後扉によって開閉される。後部床面は、車室のうち後車軸よりも車両後方の車室後部の下方を区画する。特定座席は、車室後部に設けられる。 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 rear entrance/exit is provided on the side of the vehicle behind the rear axle, and is opened and closed by a rear door. The rear floor defines the lower part of the vehicle compartment behind the rear axle of the vehicle compartment. The specific seat is provided in the rear part of the passenger compartment.

車室後部は、後乗降口の車幅方向内側に配置され、後乗降口から乗降する際の通路となる後乗降通路を含む。後部床面は、後乗降通路の下方を区画する後乗降通路床面を含む。特定座席は、起立した格納位置と格納位置から倒れた着座位置との間で傾動可能なシート座部を有する。特定座席は、着座位置のシート座部が後乗降通路床面の一部を上方から覆い、格納位置のシート座部が後乗降通路床面の上方から外れる位置に配置される。 The rear portion of the passenger compartment includes a rear passageway that is disposed inside the rear entrance in the vehicle width direction and that serves as a passage for getting in and out of the rear entrance. The rear floor includes a rear passenger aisle floor that defines the lower part of the rear passenger aisle. The specific seat has a seat portion that is tiltable between an upright stowed position and a seated position reclined from the stowed position. 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.

上記構成のバスを例えば路線バスに使用し、後乗降口を使用する態様(後扉によって後乗降口を開閉する態様)で運行する場合、特定座席のシート座部を格納位置に設定する。格納位置のシート座部は、起立して後乗降通路床面の上方から外れるので、後乗降通路を乗客が移動する際に特定座席が障害とならず、乗客は後乗降口から円滑に乗降することができる。また、乗客は、立って乗車するスペース(立ちスペース)として後乗降通路を活用することができ、車内の混雑を緩和することができる。 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.

後乗降口を使用しない態様(後扉によって後乗降口を常時閉止する態様)で運行する場合、特定座席のシート座部を着座位置に設定する。着座位置のシート座部は、格納位置から倒れて後乗降通路床面の一部に上方から重なり、乗客は、特定座席のシート座部に着座することができる。従って、後乗降通路を乗客の着座空間として有効に活用することができ、着座可能な座席数を後乗降口の使用時よりも増やすことができる。 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.

本開示によれば、後乗降口の使用時と不使用時とに応じて着座可能な座席数を変更することができ、且つ後乗降口の使用時には後乗降口からの円滑な乗降を行なうことができる。 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.

なお、非特定座席20は、特定座席19と同様に跳ね上げ式座席によって構成してもよく、シートクッション39が傾動せずに固定された非跳ね上げ式座席によって構成してもよい。また、特定座席19を含む後部座席18に、ロック機構を備えない跳ね上げ式座席を用いてもよい。 The non-specific seat 20 may be a flip-up seat similar to the specific seat 19, or may be a non-flip-up seat in which the seat cushion 39 is fixed without tilting. Also, flip-up seats without a locking mechanism may be used for the rear seats 18 including the specific seats 19 .

本実施形態のバス1を例えば路線バスに使用する場合、路線バスの運行者(例えば運行管理者や運転手など)は、後乗降口4を使用するか否かを決める。路線バスの乗客数は、運行する路線や時間帯によって異なるため、例えば乗客数が多い路線や時間帯では、後乗降口4を使用する態様(後扉9によって後乗降口4を開閉する態様)で運行し、乗客数が少ない路線や時間帯では、後乗降口4を使用しない態様(後扉9によって後乗降口4を常時閉止する態様)で運行する。 When the bus 1 of the present embodiment is used as a route bus, for example, a route bus operator (such as an operation manager or a driver) decides whether or not to use the rear entrance 4 . Since the number of passengers on a route bus varies depending on the route and time period of operation, for example, on routes and time periods with a large number of passengers, the mode of using the rear passenger door 4 (the mode of opening and closing the rear door 4 by the rear door 9). , and on routes and time zones when the number of passengers is small, it operates in a manner in which the rear entrance 4 is not used (a manner in which the rear entrance 4 is always closed by the rear door 9).

後乗降口4を使用する態様で運行する場合、路線バスの運行者(例えば運転手など)は、運行開始時に特定座席19のシートクッション39を格納位置に設定しロックする。格納位置のシートクッション39は、起立して後乗降通路床面17の上方から外れるので、後乗降通路15を乗客が移動する際に特定座席19が障害とならず、乗客は後乗降口4から円滑に乗降することができる。また、乗客は、立って乗車するスペース(立ちスペース)として後乗降通路15を活用することができ、車内の混雑を緩和することができる。 When the bus is operated using the rear entrance/exit 4, the bus operator (for example, the driver) sets and locks the seat cushion 39 of the specific seat 19 to the retracted position at the start of operation. Since the seat cushion 39 in the retracted position stands up and is removed from above the rear boarding/alighting passage floor 17, the specific seat 19 does not become an obstacle when the passenger moves in the rear boarding/alighting aisle 15, and the passenger can pass through the rear boarding/alighting opening 4.例文帳に追加You can get on and off smoothly. In addition, passengers can utilize the rear boarding/alighting aisle 15 as a space to board the vehicle while standing (standing space), thereby alleviating congestion in the vehicle.

後乗降口4を使用しない態様で運行する場合、路線バスの運行者は、運行開始時に特定座席19のシートクッション39を着座位置に設定しロックする。着座位置のシートクッション39は、格納位置から倒れて後乗降通路床面17の一部に上方から重なり、乗客は、特定座席19のシートクッション39に着座することができる。従って、後乗降通路15を乗客の着座空間として有効に活用することができ、着座可能な座席数を後乗降口4の使用時よりも増やすことができる。 When the bus is operated without using the rear entrance 4, the operator of the route bus sets and locks the seat cushion 39 of the specific seat 19 at the seating position at the start of operation. The seat cushion 39 at the sitting position falls down from the retracted position and overlaps a part of the floor surface 17 of the aisle aisle from above, so that the passenger can sit on the seat cushion 39 of the specific seat 19. - 特許庁Therefore, the rear boarding/alighting passage 15 can be effectively used as a seating space for passengers, and the number of seats that can be seated can be increased more than when the rear boarding/alighting opening 4 is used.

以上説明したように、本実施形態によれば、乗客が着座可能な座席数を、後乗降口4の使用時と不使用時とに応じて変更することができ、且つ後乗降口4の使用時には、乗客は後乗降口4からの円滑な乗降を行なうことができる。 As described above, according to this embodiment, the number of seats on which passengers can sit can be changed according to whether the rear entrance 4 is used or not, and the rear entrance 4 can be used. At times, passengers can get on and off smoothly from the rear entrance/exit 4 .

また、特定座席19を対面配置としたので、後乗降通路15を乗客の着座空間として活用する際の座席配置を効率良く行うことができる。 Further, since the specific seats 19 are arranged to face each other, it is possible to efficiently arrange the seats when utilizing the rear boarding aisle 15 as a seating space for passengers.

以上、本発明について、上記実施形態に基づいて説明を行ったが、本発明は上記実施形態の内容に限定されるものではなく、当然に本発明を逸脱しない範囲で適宜変更が可能である。すなわち、この実施形態に基づいて当業者等によりなされる他の実施形態、実施例および運用技術等は全て本発明の範疇に含まれることは勿論である。 Although the present invention has been described above based on the above embodiments, the present invention is not limited to the contents of the above embodiments, and can be appropriately modified without departing from the scope of the present invention.
