Wherein the side wings 2 are provided with cavities capable of accommodating the adaptive seat side wing filling structures 3. The side of the backrest 1 facing the wing 2 forms a first side and correspondingly the side of the wing 2 facing the backrest 1 forms a second side, which first and second sides can be brought into abutment with one another, which second side can guide the movement of the backrest 1 in the front-rear direction and in which second position the first and second sides are offset from one another. Wherein the second side may be formed with the cavity to accommodate the adaptive seat side flap filling structure 3. In other embodiments, there may be a small space between the first side and the second side to accommodate the adaptive seat side flap filling structure 3.
Wherein the adaptive seat side flap filling structure 3 has flexibility. The adaptive seat side flap filling structure 3 may be made of a flexible material such as cloth or leather that can be folded to be sandwiched between the side flap 2 and the backrest 1.
Alternatively, the edges of the support surface of the backrest 1 and the support surface of the side wing 2 engaging each other are respectively connected to the adaptive seat side wing filling structure 3. The edge of the first support surface of the backrest 1 and the edge of the second support surface of the wing 2 are defined according to the first position of the backrest 1, the two edges are the boundary of the first support surface and the second support surface in the first position, and the edge of the support surface of the backrest 1 and the edge of the support surface of the wing 2 can be specially processed during processing and manufacturing, and the two edges can be jointed in the first position during assembly to form a smooth support surface. In embodiments where the adaptive seat side flap filling structure 3 is made of a pliable material, the adaptive seat side flap filling structure 3 is attached to the edges of the first and second support surfaces so that a smooth transition can be made between the two support surfaces.
In addition, the seat structure comprises a drive assembly capable of driving the adaptive seat side wing filling structure 3 to move between the support surface of the backrest 1 and the support surface of the side wing 2.
