Examples
As shown in fig. 1-4, the embodiment of the invention provides a seat support with a low seat and a high backrest clearance, which comprises a base 1, a linkage mechanism 2, a linkage side plate 3 and a backrest mechanism 4, wherein the linkage mechanism 2 is rotatably connected between the base 1 and the linkage side plate 3, and the backrest mechanism 4 is rotatably connected with the linkage side plate 3 and the linkage mechanism 2 respectively.
The outer side surface of the linkage side plate 3 is provided with a seat frame mounting surface 31, the height of the plane where the seat frame mounting surface 31 is located is lower than the upper edge of the linkage side plate 3, and the distance H from the highest point of the seat frame mounting surface 31 to the bottom surface of the base 1 is 16cm-19cm. In this embodiment, the overall mounting height of the link side plate and the link mechanism 2 is reduced, the length of the parts in the link mechanism is shortened, the strength is increased, the height of the seat frame mounting surface 31 is reduced, and the stability of the seat frame is increased. Preferably, the distance from the highest point of the seat frame mounting surface 31 to the bottom surface of the base 1 can be 16, 17, 18 or 19cm, so that the design requirement of the low-seat high-function sofa or the seat can be met.
The backrest mechanism 4 comprises a backrest mounting piece 41 and a backrest linkage piece 42, the backrest mounting piece 41 is rotationally connected with the linkage side plate 3, two ends of the backrest linkage piece 42 are respectively rotationally connected with the backrest mounting piece 41 and the linkage mechanism 2, the backrest mounting piece 41 is used for being connected with the backrest frame 40, when the linkage mechanism 2 and the linkage side plate 3 move, the backrest mechanism 4 drives the backrest frame 40 to rotate, and the tail end edge 401 of the backrest frame 40 moves forwards or is kept on a vertical plane where the initial position of the tail end edge 401 is located.
In this embodiment, the initial position of the trailing edge 401 is the position of the trailing edge 401 when the seat frame is fully retracted to the limit position, and the plane of the trailing edge 401 at the initial position is a vertical plane, which is a plane perpendicular to the horizontal plane.
In this embodiment, the trailing edge 401 does not exceed the vertical plane in which the initial position of the trailing edge is located during the movement, which means that the trailing edge 401 does not exceed the vertical plane when moving along with the backrest frame, and the trailing edge 401 may move forward along with the backrest frame away from the vertical plane or remain on the vertical plane. Namely, the back of the seat back frame can be placed close to an adjacent object with zero clearance in the initial sitting posture state, and the seat can be extended to the lying posture position without obstacle.
Preferably, in the present embodiment, when the linkage mechanism 2 and the linkage side plate 3 move, the backrest mechanism 4 is configured to drive the backrest frame 40 to rotate, so that the tail end edge 401 of the backrest frame 40 moves in the vertical direction along the vertical plane where the initial position thereof is located. Specifically, the distance the seat frame moves forward and upward during extension is offset from the distance it is rotated rearward such that the trailing edge 401 of the back mechanism moves in a vertical direction in a vertical plane.

The smaller the angle between the backrest mounting part 411 and the horizontal plane is, the smaller the distance between the highest point of the backrest mounting part and the bottom surface of the base 1 is, so that the lower the height of the head of the seat is after extension, and the weightless lying state of the legs higher than the head can be realized after extension.
Specifically, the linkage mechanism 2 includes a first support member 21, a swinging member 22, a middle connecting member 23, a linkage member 24 and a second support member 25, where the first support member 21 and the second support member 25 are respectively rotatably disposed at two ends of the base 1, the swinging member 22 is rotatably connected with the linkage side plate 3, and two ends of the middle connecting member 23 are respectively connected with the swinging member 22 and the linkage member 24.
Specifically, the interlocking member 24 connects the middle connecting member 23, the interlocking side plate 3, the backrest interlocking member 42, and the second supporting member 25, respectively. The linkage member 24 is provided with a linkage point 241, a support connection point 242, a side plate connection point 243 and a backrest connection point 244, and is connected with the middle connecting member 23 at the linkage point 241, with the second support member at the support connection point 242, with the linkage side plate at the side plate connection point 243 and with the backrest linkage member 42 at the backrest connection point 244. Wherein the ratio of the distance L1 from the connecting point 241 to the supporting connection point 242 to the distance L2 from the supporting connection point 242 to the connection point of the second supporting member to the base is in the range of 0.6-0.7. Preferably, it may be 0.6, 0.65, 0.67 or 0.7. In this embodiment, the length of the parts of the second support member is shortened, the overall height of the linkage mechanism is reduced, the strength is increased, and the structural stability is increased.
In this embodiment, the seat support further includes a leg mechanism rotatably mounted in front of the link side plate, and the leg mechanism is capable of expanding and contracting in front of the link side plate.
In this embodiment, the driving mechanism drives the leg mechanism to expand and contract, thereby driving the linkage mechanism, the linkage side plates, and the backrest mechanism to move, so that the seat support can move between the sitting, extending, and lying positions. Wherein, the leg mechanism and the backrest mechanism are completely contracted to the limit positions in the sitting posture state; the leg mechanism extends forwards in the extending posture; the leg mechanism and the backrest mechanism are fully extended to the extreme positions in the recumbent position.
