A folding table plate for a rail transit seat comprises the seat and a seat back rotationally connected to the seat, the seat back is provided with a table plate, the seat is provided with a supporting assembly used for supporting the table plate, and a damping part used for buffering lifting of the table plate is connected between the supporting assembly and the seat; when the table plate is not unfolded, the supporting assembly and the table plate synchronously rotate along with the chair back; when the table plate is unfolded, the chair back, the supporting assembly and the table plate do not influence each other; compared with the prior art, the table board is supported through the supporting assembly rotationally connected to the seat, meanwhile, the table board cannot rotate along with the chair back when unfolded, the stability of the table board is improved, in addition, the damping piece is connected between the supporting assembly and the seat, under the action of the damping piece, the table board folded and unfolded downwards is buffered, and the stability of the table board is improved. When the table board is retracted, assistance is provided through the damping piece, and then the table board is convenient to use.
一种用于轨道交通座椅的折叠桌板,包括座椅和转动连接在座椅上的椅背,椅背上设置有桌板,所述座椅上设有用于对桌板支撑的支撑组件,支撑组件与座椅之间连接有对桌板升降提供缓冲的阻尼件;所述桌板未展开时,支撑组件与桌板跟随椅背同步转动;所述桌板展开时,椅背与支撑组件和桌板互不影响;与现有技术相比,通过转动连接在座椅上的支撑组件对桌板进行支撑,同时在桌板展开时不会跟随椅背转动,提高了桌板的稳定性,另外在支撑组件与座椅之间连接有阻尼件,在阻尼件的作用下,对向下翻折展开的桌板提供缓冲,而当桌板收回时,通过阻尼件提供助力,进而方便了桌板的使用。
