Abstract

The invention relates to a table plate for a train seat. The table plate is characterized by consisting of a supporting arm assembly structure and a bearing plate assembly structure, wherein the supporting arm assembly structure and the bearing plate assembly structure can be in rotating connection by a rotating shaft structure, the supporting arm assembly structure is formed by connecting a supporting arm body, a front housing and a back housing, and the front housing and the back housing are respectively arranged on both sides of the supporting arm body. While in use, the table plate consists of the supporting arm assembly structure and the bearing plate assembly structure, wherein the supporting arm assembly structure comprises the supporting arm body, and the supporting arm body is formed by a supporting arm framework and filling foaming by filling the foaming in a cavity. Through the adoption of the technical scheme, the table plate for the seat can be slowly opened in a first level to a limit from the backrest of the seat. The supporting arm of the table plate is independently placed at the backrest of the seat. After the table plate is opened, a passenger can pull and push by hands to adjust the horizontal position of the table plate according to different requirements. The table plate is convenient to operate. Besides, the table plate can be used for safely and steadily bearing articles with certain weight.

Description

technical field [0001] The invention relates to the technical field of train seats, in particular to a table board for train seats.
