[0034] The seat assembly disclosed in the present utility model mainly includes a seat skeleton and a backrest skeleton 2; the seat skeleton and the backrest skeleton 2 are the main structures of the seat assembly, and in the present utility model, a seat support is provided on the seat skeleton, and the seat support is a movable part. During subsequent use, it can be used to lift the seat cushion, which is convenient for locally supporting and raising the seat cushion to make up for the height difference between the seat cushion and the backrest.

[0035] At the same time, in the present utility model, one end of the seat support away from the backrest skeleton 2 is connected to the seat skeleton through a rotating mechanism; one end of the seat support close to the backrest skeleton 2 is connected to the backrest skeleton 2 through a linkage mechanism; the backrest skeleton 2 can drive the seat support to rotate through the linkage mechanism; based on the above design, the setting of the rotating mechanism enables one end of the seat support to have a rotating fulcrum, which is convenient for subsequent rotating and raising operations, and the setting of the linkage mechanism, firstly, plays a bridging role, and secondly, realizes the connection between the backrest and the seat support. Subsequently, the seat cushion support 10 can be driven to rotate by laying down the backrest, so as to realize the linkage between the backrest laying down and the seat cushion adjustment; the rotating mechanism and the linkage mechanism are distributed on opposite sides of the seat support, which is convenient for one end to act as a rotating fulcrum and the other end to act as an external force application point.

[0036] In addition, in the present utility model, the rotating mechanism can be a rotating shaft, a rotating pin, a hinge or other structures. Theoretically, as long as the rotating connection of the seat support member can be achieved, it can be used.

[0037] Further, in the present utility model, the linkage mechanism includes a transfer bracket 12, a driving rod 3, a linkage rod 4 and a rotating rod 5; one end of the transfer bracket 12 is connected to the backrest frame 2, and the other end is connected to the driving rod 3; the driving rod 3 is connected to the rotating rod 5 through the linkage rod 4, and the rotating rod 5 is connected to the seat support member; the transfer bracket 12, the driving rod 3, the linkage rod 4 and the rotating rod 5 are sequentially movably connected; the rotating rod 5 is also movably connected to the seat support member; the linkage rod 4 is rotatably connected to the seat frame; one end of the linkage rod 4 is connected to the driving rod 3, and the other end is connected to the rotating rod 5; by pulling the driving rod 3, the rotating rod 5 can be driven to move through the linkage rod 4, and the rotating rod 5 can drive the seat support member to rotate around the rotating mechanism; in the present utility model, the transfer bracket 12, the driving rod 3, the linkage rod 4 and the rotating rod 5 form a linkage mechanism. During subsequent use, when the backrest flips, the backrest frame 2 drives the rotating bracket 11 to rotate, the rotating bracket 11 drives the driving rod 3 to rotate, the driving rod 3 pulls the linkage rod 4 to rotate, the linkage rod 4 rotates to drive the rotating rod 5 to move upward, the rotating rod 5 moves upward to drive one end of the seat support member to move upward, and due to the limitation of the rotating mechanism, the seat support member will rotate. Based on the rotation of the seat support member, the longitudinal support force of the seat cushion near the backrest end will be increased, so as to realize the lifting of the rear end of the seat cushion, thereby compensating for or reducing the height difference between the rear end of the seat cushion and the backrest.

[0038] In the present utility model, the transfer bracket 12, the driving rod 3, the linkage rod 4 and the rotating rod 5 are sequentially movably connected; the rotating rod 5 is also movably connected to the seat support member; here, the movable connection can be a hinge connection or a connection through a rotating shaft or a rotating pin.

[0039] In addition, in the present utility model, the linkage rod 4 is connected to the seat frame through a rotating member. The setting of the rotating member plays a role in position limitation and also acts as a rotating fulcrum, facilitating the subsequent rotation of the linkage rod 4 around the rotating member on the seat frame, facilitating the subsequent pulling of the rotating rod 5 by the driving rod 3 through the linkage rod 4, and the linkage rod 4 acts similar to a lever structure.

[0040] In the present utility model, the rotating member includes a rotating column 6; the linkage rod 4 can rotate around the rotating column 6; the rotating column 6 is a rotating shaft structure; it facilitates the installation and fixation of the linkage rod 4 on the seat frame; at the same time, it does not affect the rotation operation of the linkage rod 4.

[0041] In addition, in the present utility model, the rotating column 6 is connected to the seat frame through a bolt mechanism; the bolt mechanism includes a rotating bushing 8.

[0042] In the present utility model, the bolt mechanism plays a role of connection and fixation, facilitating the installation of the linkage rod 4 on the seat frame.

[0043] In the present utility model, the bolt mechanism includes a rotating bushing 8, facilitating the connection of the linkage rod 4 to the rotating column 6. In order to realize the installation of the rotating column 6 on the seat frame, in the present utility model, the rotating column 6 is connected to the seat frame through the rotating bushing 8. A stepped bolt 7 is provided on the rotating column 6, and a nut 9 is provided at the end of the stepped bolt 7; the stepped bolt 7 is inserted into the rotating column 6 and then inserted into the seat frame, thereby realizing the installation and fixation of the linkage rod 4 on the seat frame; in addition, in the present utility model, the rotating column 6 is generally a metal cylinder.

[0044] Furthermore, in the present utility model, the linkage rod 4 includes a first rod body 41 and a second rod body 43, and the first rod body 41 and the second rod body 43 are connected through a connecting plate 42; the first rod body 41 and the second rod body 43 are staggeredly distributed in two planes; based on such a setting, the first rod body 41 and the second rod body 43 are staggeredly distributed, and such a setting can avoid the movement interference between the driving rod 3 and the rotating rod 5 when the linkage rod 4 rotates; in the present utility model, the orthographic projection of the linkage rod 4 is U-shaped; in actual arrangement, the first rod body 41 is above the second rod body 43, the connecting plate 42 is a bent plate, and the horizontal projections of the first rod body 41 and the second rod body 43 do not coincide or do not completely coincide. With such a setting, when the linkage rod 4 rotates in the longitudinal plane, the driving rod 3 and the rotating rod 5 will not have interference problems during installation and movement; at the same time, in the present utility model, the driving rod 3 is connected to the second rod body 43, and the rotating rod 5 is connected to the first rod body 41. With such a setting, when the backrest is reclined, the longitudinal pulling operation of the seat support member can be realized.
