Embodiment Construction

[0024] Below in conjunction with the drawings, preferred embodiments of the present invention are given and described in detail.

[0025] like Figure 1-Figure 2 As shown, the seat with the self-balancing structure according to the first preferred embodiment of the present invention includes a seat frame 1, a four-bar linkage mechanism 2, a rotating shaft 3 and a table board 4, wherein the seat frame 1 includes a backrest 11 and The seat cushion 12 and the table board 4 are self-balancedly installed on the backrest 11 through the four-bar linkage mechanism 2 and the rotating shaft 3 . In particular, the four-bar linkage mechanism 2 has a stopper 21 that is rotatably installed on the seat frame 1, and the backrest 11 is in the full stroke of turning over relative to the seat cushion 12 (including figure 1 The process of folding back from the design position and figure 2 shown in the process of turning forward from the design position), the angle of rotation of the backrest 1...

Abstract

The invention relates to a seat with a self-balancing structure. The seat comprises a seat framework, a four-bar mechanism, a rotating shaft and a structural member; the seat framework comprises a backrest and a seat cushion; the structural member is mounted on the backrest in a self-balancing manner through the four-bar mechanism and the rotating shaft; the four-bar mechanism is provided with a blocking piece rotatably mounted on the seat framework; the rotating angle of the backrest relative to the cushion is extracted by the blocking piece and compensated to the structural member through the four-connecting-rod mechanism and the rotating shaft so that the structural member can be kept at the horizontal position all the time. According to the seat with the self-balancing structure, the relative rotation angle of the backrest and the cushion is extracted through the blocking piece when the backrest is turned over, and the angle equal to the rotation angle is compensated to the structural member through the four-bar mechanism and the rotating shaft, so that the structural member is always horizontal relative to the floor. In a word, the seat with the self-balancing structure is simple in structure, relatively low in cost and suitable for various seat framework platforms.

Description

technical field [0001] The invention relates to a seat, more particularly to a seat with a self-balancing structure. Background technique [0002] It is known to provide a table on the backrest of the seat for the convenience of rear passengers. When the backrest is adjusted forward or backward, the table will tilt along with the backrest, affecting user experience. In order to solve this problem, someone proposed a related solution on the electrically adjustable seat, that is, the gearbox-flexible shaft drive. The steering and speed are changed through the gear box drive mechanism, and the rotation of the synchronous rod of the recliner is converted into the rotation of the table to keep the table level during use. Apparently, the applicability of this self-leveling table is only limited to electrically adjustable seats, and the structure is complicated and the cost is high. Contents of the invention [0003] In order to solve the above-mentioned problem in the prior a...
