The present invention is characterized in that the present invention is relatively fixed, and the bogie 20 rotates on the holder 10, and the three moving members move in the same plane. The bogie 20 is generally rotatably regulated in the horizontal plane. It is hinged with the three moving members by three fixed points. By the synchronous constraint of the three moving parts, the bogie 20 can only rotate within the limited range in the plane, and realizes the adjustment of a specific direction. The present invention can realize the direction change of the bogie 20 within the limited range, and has higher supporting performance, and its structure is flat, thin and compact. The seat cushion can be installed on the bogie 20 and the steering adjustment of the seat cushion can be carried out. The tops of the first moving member 41, the second moving member 42, and the third moving member 43 are provided with an erected rotating shaft 60, and corresponding axle holes are arranged on the bogie 20 to be connected with the three rotating shafts 60.

[0044] Furthermore, in the steering support seat provided by the present invention, the first movable part 31 and the second movable part 32 are symmetrically arranged, and the third movable part 33 is arranged at the symmetrical center of the first movable part 31 and the second movable part 32. The left-right symmetrical arrangement of the first movable part 31 and the second movable part 32 can make the left and right steering ranges of the bogie 20 also symmetrical and consistent. Further, in the steering support seat provided by the present invention, the first movable part 31 is a slide rail, the first movable member 41 is a slider, the second movable part 32 is a slide rail, the second movable member 42 is a slider, the third movable part 33 is a slide rail, and the third movable member 43 is a slider, and the slider slides on the corresponding slide rail. The sliding of the slider on the slide rail can ensure smooth and noiseless sliding. The use of slide rails and sliders in the present invention is only a preferred solution for relative movable connection. Similarly, alternative structures with similar effects such as slide grooves and sliders can also be used, which are also within the scope of the present invention. Furthermore, the steering support seat provided by the present invention, the first movable part 31 is a linear slide rail, the second movable part 32 is a linear slide rail, the ends of the first movable part 31 and the second movable part 32 on one side are close to each other, and the ends of the first movable part 31 and the second movable part 32 on the other side are far away from each other. The bogie 20 of this embodiment is a T-shaped frame or a Y-shaped frame, and the connection points between the first movable member 41 and the second movable member 42 and the bogie 20 are symmetrically arranged on the left and right sides of the bogie 20. Further, the steering support seat provided by the present invention, the third movable part 33 is a linear slide rail, and the third movable part 33 is arranged on the center line between the first movable part 31 and the second movable part 32. The middle part of the bogie 20 is connected to the third movable member 43, and the three connection points between the bogie 20 and the three movable members are not on the same straight line. The first movable part 31 and the second movable part 32 are arranged obliquely, and an angle is formed between the two, with the angle side as the inner side. In this way, when the bogie 20 turns left, the left end of the bogie 20 (the first movable part 31) moves inward, and the right end of the bogie 20 (the second movable part 32) moves outward until the first movable member 41 moves to the inner end of the first movable part 31. At this time, the bogie 20 turns right, the left end of the bogie 20 moves outward, and the right end of the bogie 20 moves inward until the second movable member 42 moves to the inner end of the second movable part 32. During this unidirectional rotation process, the third movable member 43 will move outward and then move inward to complete a reciprocating motion.

[0045] Preferably, in the steering support seat provided by the present invention, an orienting member 51 is provided between the bogie 20 and the fixing seat 10. The orienting member 51 is fixed to the bogie 20. A positioning portion 52 is provided on the fixing seat 10, and the orienting member 51 is docked with the positioning portion 52. The docking of the orienting member 51 and the positioning portion 52 can achieve the purpose of maintaining the bogie 20 at a specific steering angle.

[0046] Furthermore, the steering support seat provided by the present invention comprises a directional member 51 including a positioning post 53, wherein a ball 55 is disposed within the positioning post 53 and an elastic member 54 that drives the ball 55 to partially protrude from the bottom of the support portion. The elastic member 54 can be a spring. The positioning portion 52 is provided with at least two, each of which is a positioning recess that engages with the ball 55. In this embodiment, the bogie 20 has a rotation angle of 90° and two positioning recesses are provided symmetrically on both sides. A certain gap exists between the positioning post 53 and the fixed seat 10. During steering, the ball 55 of the positioning post 53 rolls on the fixed seat 10. When the positioning post 53 moves above the positioning recess, the ball 55 is pressed into the positioning recess by the elastic member 54. The user can hear a click, indicating that the steering has been adjusted to the desired angle. When the ball 55 is about to move out of the positioning recess, this structure provides a certain resistance, ensuring a certain retention force when steering to the preset angle.

[0047] Furthermore, the steering support seat provided by the present invention, the directional member 51 also includes a limit plate 56, the limit plate 56 is fixedly connected to the directional member 51, and the fixed seat 10 is provided with a limit block 57 that cooperates with the limit plate 56. In this embodiment, there are two limit blocks 57, which are symmetrically arranged on the left and right, and are used to limit the left and right movement range of the bogie 20, and are in conflict with the two ends of the limit plate 56. Further, the steering support seat provided by the present invention, the limit block 57 is also provided with a limit cover 58, and the limit plate 56 moves from under the limit cover 58. The limit plate 56 is located in the gap between the limit cover 58 and the fixed seat 10 and moves, and the limit plate 56 does not contact either of them. Further, the steering support seat provided by the present invention, one end of the limit cover 58 is provided with an introduction inclined plate 59, and the introduction inclined plate 59 is located below the bogie 20. The guide inclined plate 59 is tilted upward to guide the limit plate 56 to move into the limit cover 58, and the limit cover 58 is located on one side of the positioning pit and is used to accommodate the upward movement of the limit plate 56 after it enters and docks with the positioning pit.

[0048] In summary, the fixed seat of the present invention is relatively fixed, the bogie rotates on the fixed seat, and the three movable parts move within the same plane. The bogie is generally rotated and adjusted within a horizontal plane. It is articulated with the three movable parts at three fixed points. Through the synchronous constraints of the three movable parts, the bogie can only rotate within a limited range within the plane, achieving adjustment in a specific direction. The present invention can achieve directional changes of the bogie within a limited range and has high support performance. In addition, its structure is flat, thin and compact, and a seat cushion can be installed on the bogie for steering adjustment.
