DETAILED DESCRIPTION

[0031] The present invention will be further described below by way of embodiments and in conjunction with the accompanying drawings:

[0032] like Figure 1-Figure 13 As shown, a manual table installed on a seat back mainly consists of a folding table 1, a connecting rod assembly, a pop-up assembly, an unlocking assembly 16 and a shielding assembly, wherein the folding table 1 is arranged on the rear side of the seat back lining 2 through the connecting rod assembly, and a pop-up assembly is arranged on the front side of the seat back lining 2, and the folding table 1 can be turned over and unfolded with the assistance of the pop-up assembly, and the folding table 1 is unlocked and popped out by the unlocking assembly arranged on the upper end of the seat back lining 2, and a shielding assembly for shielding the folding table 1 after it pops out is arranged on the seat back lining 2. The unlocking assembly adopts the existing technology and will not be described in detail here.

[0033] like Figure 1 , 2As shown in Figure 4, there is one group of connecting rod assemblies on the left and right, and each group of connecting rod assemblies includes an upper connecting rod 3, a lower connecting rod 4 and a connecting rod mounting bracket 5. The connecting rod mounting bracket 5 is mounted on the rear side of a table board fixing bracket 6 arranged on the front side of the seat back lining 2. A table board door hole is arranged on the seat back lining 2, one end of the upper connecting rod 3 is hinged on the folding table board 1, and the other end of the upper connecting rod 3 is hinged to the upper end of the connecting rod mounting bracket 5 after passing through the table board door hole, one end of the lower connecting rod 4 is hinged on the folding table board 1, and the other end of the lower connecting rod 4 is hinged to the lower end of the connecting rod mounting bracket 5 after passing through the table board door hole.

[0034] like Figure 2 and Figure 5 As shown, there is one pop-up assembly on each side, and each pop-up assembly includes a pop-up spring 7 located on the front side of the seat back lining 2, one end of the pop-up spring 7 is pressed on the front side of one end of the upper connecting rod 3 and the connecting rod mounting bracket 5, and the other end is arranged on the front side of the table board fixing bracket 6 through the corresponding spring bracket 17. The pop-up spring adopts a leaf spring, which is not only simple in structure, but also convenient to meet the torque requirements and space requirements, and can be separated from the installation of the connecting rod assembly during installation, so as to facilitate installation.

[0035] The shielding assembly includes two upper shielding assemblies and two lower shielding assemblies which are symmetrically arranged on the left and right. The upper shielding assembly is used to shield the position where the upper connecting rod 3 extends out of the table door opening after the folding table 1 is unfolded, and the lower shielding assembly is used to shield the position where the lower connecting rod 4 extends out of the table door opening after the folding table 1 is unfolded. After the folding table is unfolded, the corresponding upper shielding assembly and lower shielding assembly can block the gap where the connecting rod extends out, thereby ensuring the integrity and aesthetics of the seat, and at the same time preventing the folding table from randomly extending into the gap and pinching the hands when it is unfolded.

[0036] The lower shielding assembly includes a lower shielding valve 8 located on the front side of the seat back lining 2, and a U-shaped lower buckle 9 is provided at the lower position of the front side of the seat back lining 2, wherein the lower end of the lower shielding valve 8 is hinged on the lower buckle 9, and the lower shielding valve 8 is equipped with a lower return spring 10. When the folding table 1 is unfolded, the lower shielding valve 8 can return to its original position under the action of the lower return spring 10 and achieve shielding at the position where the lower connecting rod 4 extends out of the table door opening. The lower shielding valve is arranged on the seat back lining through a hinge shaft, which not only simplifies the movement of the lower shielding valve, but also can be directly pre-installed on the seat back lining during assembly, thereby facilitating installation.

[0037] like Figure 6-9As shown, the specific structure of the upper shielding assembly may include an upper shielding valve 11 located on the front side of the seat back lining 2, a U-shaped upper buckle 12 is provided at the upper position of the front side of the seat back lining 2, the upper end of the upper shielding valve 11 is hinged on the upper buckle 12, and the upper shielding valve 11 is equipped with an upper return spring 13. When the folding table 1 is unfolded, the upper shielding valve 11 can return to its position under the action of the upper return spring 13 and achieve shielding at the position where the upper connecting rod 3 extends out of the table door opening.

[0038] It can also be, Figure 10-13 As shown, the upper shielding assembly includes an upper shielding valve 11 located on the front side of the seat back lining 2, the upper end of the upper shielding valve 11 is hinged on the upper connecting rod 3, and the upper shielding valve 11 is equipped with an upper return spring 13. When the folding table 1 is unfolded, the upper shielding valve 11 can return to its original position under the action of the upper return spring 13 and achieve shielding at the position where the upper connecting rod 3 extends out of the table door opening.

[0039] Preferably, there are structures for installing the upper shielding valve on both the upper connecting rod and the seat back lining, so that the upper shielding valve can be installed in a manner selected according to the actual space, thereby improving the versatility of the installation of the upper shielding assembly.

[0040] Preferably, an upper extension section is extended at one end of the upper connecting rod 3, and an upper thrust rubber block 14 is provided on the rear side of the upper extension section or the front side of the upper end of the upper shielding valve 11. A lower extension section is extended at one end of the lower connecting rod 4, and a lower thrust rubber block 15 is provided on the rear side of the lower extension section or the front side of the upper end of the lower shielding valve 8. When the folding table is unfolded, the upper connecting rod and the lower connecting rod can be pressed on the corresponding shielding valve through the corresponding thrust rubber blocks, so that the shielding valve cannot be pressed in when the folding table is in use, thereby effectively preventing the occurrence of hand pinching. During installation, the upper thrust rubber block and the lower thrust rubber block can be directly attached to the corresponding position through the adhesive backing.

[0041] In order to prevent the upper shielding valve 11 and the lower shielding valve from rotating to outside the corresponding connecting rod extended position under the action of the corresponding return spring, the upper shielding valve 11 and the lower shielding valve 8 are provided with limiting edges.
