Cross-Reference to Related Application

[0001] The present invention claims the priority of Chinese Patent Application No. 201910101631.5, 201920165639.3, filed to the Chinese Patent Office on January 30, 2019 and entitled "Seat Mounting Structure and Train Having Same".Technical Field

[0002] The present invention relates to the field of train apparatuses, in particular to a seat mounting structure and a train having same.Background

[0003] Rail transit refers to a means of transport or transportation system in which an operating vehicle needs to travel on a particular rail. The most typical rail transit is a railway system consisting of traditional trains and standard railways. As the train and railway technologies develop diversely, the rail transit also becomes increasingly diversified. It is spread over long-distance land transportation, and is also widely applied to medium and short-distance urban public transportation.

[0004] In the seat design of an existing rail vehicle, a transverse seat can provide a more comfortable seat environment than a longitudinal seat. In order to guarantee the structural strength, as shown in Fig. 1, a traditional transverse seat 1 needs to be fixed at the train side wall 2, and moreover, a support leg 3 needs to be additionally provided on the aisle side. The support leg 3 of the transverse seat 1 influences the attractiveness and increase the actual space occupation, which hinders the arrangement of other structures.

[0005] As shown in Fig. 2, the transverse seat structure is improved to a cantilever seat 4, since the support leg at the aisle is omitted, the strength of the seat is guaranteed by additionally arranging a support member 5 at the side wall, and a common structure is provided with a T-shaped support and an inclined supporting beam. The improved cantilever seat 4 is compact in structure, smaller in occupied space and more convenient to clean from below.

[0006] However, the size of the mounting base at the side wall is increased due to the cantilever seat, and a cover plate is usually required to be mounted to shield the mounting base, which influences the overall sealing of the side wall while the attractiveness is influenced, and the overall weight is also increased. In addition, the support area of the mounting base at the side wall is limited, and therefore cannot provide effective support for the aisle side of the seat. Consequently, the seat obviously sinks when used, which affects riding comfort. Meanwhile, the structural strength of the cantilever seat has certain defects.

[0007] US3630566A discloses an end-supported vehicles seat. One end of a vehicle seat is anchored at spaced points to the wall of the vehicle and the other end at the aisle is suspended from the ceiling by a suspension rod or tube braced against turning.

[0008] US5464273A discloses a seat construction. The seat construction includes a composite inner / outer frame to which at least two seat pans are secured.

[0009] EP3257703A1 discloses a passenger transport vehicle comprising a suspended seating device.

[0010] US6416116B1 discloses an interior structure of a mass transit vehicle. A public transit vehicle has a vehicle body having a roof defining an interior ceiling surface. Two side walls each extending longitudinally of the vehicle including an upper side wall portion connecting to the roof and a row of windows underneath the upper portion.Summary
