[0062] a first locking member 30, and a first unlocking member 90 for unlocking the first locking member 30;

[0063] a second locking member 50, and a second unlocking member 60 for unlocking the second locking member 50;

[0064] a table frame lower track 20 fixed to the vehicle floor, a table frame upper track 21 slidably disposed on the table frame lower track 20, and the table frame upper track 21 and the table frame lower track 20 are connected in a releasable manner by the first locking member 30;

[0065] a table frame 40 fixed to the table frame upper track 21, and the table frame 40 and the seat 10 are connected in a releasable manner by the second locking member 50;

[0066] The holding mechanism 70 is provided on the table frame 40. After the first locking member 30 is unlocked, it is held in the unlocked state by the holding mechanism 70;

[0067] When the table frame 40 is used outside the seat 10, the upper track and the lower track 20 of the table frame are locked and connected by the first locking member 30; before the table frame 40 is stored and moved, the locking connection between the upper track 21 of the table frame and the lower track 20 of the table frame is released by the first unlocking member 90;

[0068] When the table frame 40 moves under the seat 10, the seat 10 triggers the holding mechanism 70 to keep the upper track 21 and the lower track 20 of the table frame in the unlocked state, and the table frame 40 and the seat 10 are locked and connected by the second locking member 50.

[0069] As a preferred embodiment of the table board of the vehicle seat of the present invention, in combination with Figures 5 to 11 As shown, the first locking member 30 includes: a bolt 31 movably provided laterally on the side of the upper track 21 of the table frame; a slot 32 provided on the side of the lower track 20 of the table frame; the locking connection is achieved by inserting the bolt 31 into the slot 32.
