As shown in fig. 16 to 18, in the seat structure for a railway vehicle provided in the present embodiment, when the seat panel assembly is connected to the seat frame 30, the specific second support frame 603 is connected to all the first support frames 303 through the seventh connecting member 602, and the seat lower cover 50 is connected to the bottoms of the first support frames 303, so that the installation of the seat structure for a railway vehicle is completed. The inner wall 110 of the vehicle body is provided with a C-shaped groove for mounting the seat frame 30, and the fourth connecting member 305 is connected with the C-shaped groove by fasteners such as a slider, a bolt, a nut and the like, so that the whole seat is mounted on the inner wall 110 of the vehicle body.

The seat structure for the rail vehicle provided by the embodiment adopts the seat panel and the seat framework, strengthens the structure of the framework and the seat framework through the reasonable arrangement of the seat panel, enhances the capability of bearing external load of the seat, and improves the strength of the seat. Particularly, the subway station has great advantages on subways with more and more passengers. Through the smaller size of the section of the seat framework, the size of the seat end plate is correspondingly smaller, the weight of the seat is reduced, and the design of wind shield parts is avoided.

The embodiment also provides a railway vehicle, which comprises the seat structure for the railway vehicle provided by the embodiment.

The structure and the working principle of the seat structure for the rail vehicle have been described in detail in the above embodiments, which are not repeated herein.

The rail vehicle that this embodiment provided adopts the seat structure that is used for rail vehicle, adopts seat panel and seat skeleton, strengthens skeleton and seat skeleton's structure through the rational arrangement seat panel, has strengthened the ability that the seat bore external load, has improved seat intensity. Particularly, the subway station has great advantages on subways with more and more passengers. Through the smaller size of the section of the seat framework, the size of the seat end plate is correspondingly smaller, the weight of the seat is reduced, and the design of wind shield parts is avoided.
