[0051] like Figure 5 and Figure 7 As shown, a first slide groove 185 and a second slide groove 186 are formed in the sliding track 181, and a first roller 183 and a second roller 184 are respectively provided in the first slide groove 185 and the second slide groove 186. The first roller 183 and the second roller 184 can be connected by rivets. The first roller 183 and the second roller 184 rotate in the first slide groove 185 and the second slide groove 186 respectively. The number of the sliding rails 181 corresponds to the number of the linkage rods 182. One end of the linkage rod 182 is connected to the first roller 183 and the second roller 184. The second linkage member 142 is fixedly connected, and the other end of the linkage rod 182 is connected to the first roller 183 and the second roller 184. The second driving member 152 drives the second linkage member 142 to rotate, thereby driving the linkage rod 182 to move. The linkage rod 182 drives the first roller 183 and the second roller 184 to rotate in the first slide groove 185 and the second slide groove 186 respectively, thereby adjusting the distance between the linkage rod 182 and the sliding track 181. The linkage rod 182 cooperates with the second linkage member 142 to drive the first backrest side panel 1 21 and the second backrest side plate 122 rotate relative to the base 11; wherein, the first roller 183 abuts against one side surface of the first slide groove 185 in the thickness direction, and the second roller 184 abuts against the second slide groove 186 on the other side in the thickness direction, thereby reducing the gap between the first roller 183 and the first slide groove 185 in the thickness direction, and reducing the gap between the second roller 184 and the second slide groove 186 in the thickness direction, so that the seat assembly 1 is more stable during the coordinated movement through the linkage rod 182 and the first roller 183 and the second roller 184, avoiding the gap between the first roller 183 and the first slide groove 185 in the thickness direction, thereby avoiding the collision and friction noise between the first roller 183 and the first slide groove 185 during the movement of the first roller 183 in the first slide groove 185, and similarly, avoiding the collision and friction noise between the second roller 184 and the second slide groove 186 during the movement of the second roller 184 in the second slide groove 186, thereby improving the stability of the seat assembly 1.

[0052] According to one embodiment of the present invention, the first roller 183 and the second roller 184 are coaxially arranged and have different diameters.

[0053] like Figure 7As shown, the first roller 183 and the second roller 184 are coaxially arranged, and the first roller 183 and the second roller 184 can be fixed by rivets to improve the connection stability of the first roller 183 and the second roller 184. The first roller 183 and the second roller 184 have different diameters, which can ensure that when one of the first roller 183 and the second roller 184 is stuck, the other one of the first roller 183 and the second roller 184 can continue to move, ensuring that the first roller 183 and the second roller 184 can operate stably.

[0054] According to one embodiment of the present invention, the first roller 183 is spaced apart from the first sliding groove 185 on one side in the width direction and / or the second roller 184 is spaced apart from the second sliding groove 186 on the other side in the width direction.

[0055] Specifically, the first roller 183 is spaced apart from the first slide groove 185 on one side in the width direction, so that a gap is left between the first roller 183 and the first slide groove 185 on one side in the width direction, so that during the rotation of the first roller 183 in the first slide groove 185, the first roller 183 will not be stuck by the first slide groove 185 on one side in the width direction, thereby ensuring smooth operation of the first roller 183; the second roller 184 is spaced apart from the second slide groove 186 on the other side in the width direction, and a gap is left between the second roller 184 and the second slide groove 186 on the other side in the width direction, so that during the rotation of the second roller 184 in the second slide groove 186, the second roller 184 will not be stuck by the second slide groove 186 on the other side in the width direction, thereby ensuring smooth operation of the second roller 184.
