In the present invention, the use of directional terms such as "front, rear, left, right" generally refers to relative positions with reference to the seat, unless otherwise specified.

The invention provides a seat structure, wherein the seat structure comprises a backrest 1, a side wing 2 and an adaptive seat side wing filling structure 3, the backrest 1 can move in the front-back direction relative to the side wing 2 between a first position and a second position, in the first position, a supporting surface of the backrest 1 and a supporting surface of the side wing 2 are smoothly jointed, in the second position, the supporting surface of the backrest 1 and the supporting surface of the side wing 2 are staggered, and the adaptive seat side wing filling structure 3 forms smooth transition between the supporting surface of the backrest 1 and the supporting surface of the side wing 2.

The seat structure comprises a backrest 1, wherein the backrest 1 can support the back of an occupant, and the backrest 1 can move in the front-back direction to adapt to the occupants with different sizes and different sitting postures.

The side wings 2 are structures provided on both lateral sides (may be provided only on one side) of the backrest 1, which protrude forward with respect to the support surface of the backrest 1, as shown in fig. 3, and can provide support to the occupant in the lateral direction and restrict excessive movement of the occupant in the lateral direction.

When the backrest 1 is in a first position (which may be an extreme position of forward movement of the backrest 1), the support surfaces of the backrest 1 (hereinafter referred to as first support surfaces) and the wing 2 (hereinafter referred to as second support surfaces) are smoothly connected together, and there are substantially no dislocations or steps; when the backrest 1 is moved rearwardly to the second position, the first and second support surfaces are staggered to form a step, in which case the support surface of the adaptive seat side flap filling structure 3 (hereinafter referred to as the third support surface) may be disposed between the first and second support surfaces to provide a smooth transition therebetween to form a complete smooth support surface.

The adaptive seat side flap filling structure 3 may be a sheet, but may also be a block or other shape as long as a support surface that provides a smooth transition between the backrest 1 and the side flap 2 can be formed.

In this scheme, self-adaptation formula seat flank filling structure can provide the holding surface between the back that staggers each other and flank to form complete level and smooth holding surface, eliminated the step difference and the clearance between back and the flank, can avoid article to fall into the interval, both promoted the travelling comfort of seat, also guaranteed pleasing to the eye effect.

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. The left-right direction is a lateral direction of the seat structure. When the backrest 1 is moved to the second position, the drive assembly may drive the adaptive seat side wing filling structure 3 to move between the first and second support surfaces such that the third support surface engages with the first and second support surfaces to form a smooth support surface. For example, the adaptive seat side wing filling structure 3 is located in the cavity when the backrest 1 is in the first position, and the driving assembly drives the adaptive seat side wing filling structure 3 to move when the backrest 1 is moved to the second position, but of course, such movement may be only a portion of the adaptive seat side wing filling structure 3, for example, when it is connected to an edge of the first support surface and an edge of the second support surface, or may be a movement of the whole, for example, in the case where the adaptive seat side wing filling structure 3 is a rigid support structure.

Specifically, the driving assembly comprises a motor 5 and a transmission screw 6. The motor 5 can output torque, and the transmission screw 6 can convert the torque into acting force along a straight line. The motor 5 may be mounted on the adaptive seat side wing filling structure 3 or on the side wing 2. As shown in fig. 4, the seat structure may be provided with two sets of driving assemblies, that is, the adaptive seat side wing filling structure 3 may be stably supported by the driving screw 6 acting on the adaptive seat side wing filling structure 3 at two points.

The control element may be a control element provided separately in the seat structure, or may be a BCM (body control module) of the vehicle. When the backrest 1 needs to be moved backwards to the second position, the control element controls the backrest 1 to move backwards first, and then controls the adaptive seat side wing filling structure 3 to move between the backrest 1 and the side wing 2; when it is desired to move the backrest 1 forward to the first position, the control unit controls the adaptive seat side wing filling structure 3 to move back into the cavity of the side wing 2, and then controls the backrest 1 to return to the first position.

Optionally, the motor 5 is mounted on the side wing 2, and the transmission screw 6 is in transmission connection with the motor 5 and the adaptive seat side wing filling structure 3. The motor 5 can be mounted inside the wing 2 or in the cavity described above, and the drive screw 6 comprises a lead screw which can be drivingly connected to the motor 5 and a nut which is connected to the adaptive seat side wing filling structure 3, so that the motor 5 can drive the adaptive seat side wing filling structure 3 to move, on the one hand, to a position in which it is smoothly connected to the first support surface and the second support surface, and on the other hand, from this position back to the initial position, such as the cavity on the wing 2.

In addition, the seat structure comprises a support plate (not shown in the drawing) arranged on the back of the adaptive seat side wing filling structure 3, and the transmission screw 6 is connected with the support plate in a transmission manner. The support plate is a rigid member and can provide support for the adaptive seat side flap filling structure 3, so that the adaptive seat side flap filling structure 3 can be unfolded, especially if the adaptive seat side flap filling structure 3 is made of a flexible material. In addition, the supporting plate can be used as a medium for connecting the self-adaptive seat side wing filling structure 3 with the transmission screw rods 6, when two sets of driving assemblies are arranged, the two transmission screw rods 6 are connected to the supporting plate, and the supporting plate can enable the two transmission screw rods 6 to move synchronously.

In addition, the seat structure comprises a fixed plate 4 arranged on the side wings 2, and the motor 5 is arranged on the fixed plate 4. The fixing plate 4 provides a mounting base for the motors 5, wherein, when two motors 5 are provided, the fixing plate 4 can enable the two motors 5 to be mounted at specific relative positions so as to ensure that the adaptive seat side wing filling structure 3 stably moves under the action of the two transmission screw rods 6.

The back rest 1 can move horizontally or rotate around a rotating shaft at the lower part; the motor 5 can be controlled by a control element of the vehicle and a contact switch or a distance sensor can be provided at the backrest 1 which is connected to the control element and which is triggered when the backrest 1 is moved into the second position or which detects the movement of the backrest 1 into the second position, whereupon the control element can control the motor 5 such that the adaptive seat side wing filling structure 3 is moved into a suitable position to form a smooth support surface between the backrest 1 and the side wing 2.
