[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] In this technical solution, an automotive seat cushion mounting base includes a seat body 1. A tightening mounting structure is installed at the lower end of the seat body 1. The tightening mounting structure includes a fixing frame 2, a connecting plate 3, fixing bolts 4, a mounting plate 5, four bearing plates 6, a winding assembly, and a positioning assembly.

[0026] The upper end of the fixed frame 2 is fixedly connected to the lower wall of the seat body 1. One end of the connecting plate 3 is movably embedded in the fixed frame 2. The fixing bolt 4 is movably embedded in the center of the lower wall of the fixed frame 2. The mounting plate 5 is fixedly installed on one side of the connecting plate 3. Four bearing plates 6 are respectively installed on one side of the lower end of the mounting plate 5. The winding assembly is movably embedded in the four bearing plates 6. The positioning assembly is installed on both sides of the lower wall of the mounting plate 5, and one end is movably embedded in the winding assembly.

[0027] In this technical solution, during installation, the workers first fix the fixing frame 2 to the lower end of the seat body 1 by welding or gluing. Then, one end of the connecting plate 3 is embedded into the fixing frame 2, and the connecting plate 3 is fixed by fixing bolts 4. Next, the seat cushion and backrest cushion are laid on the seat body 1 and the seat back. The straps of the seat cushion and backrest cushion are passed through the gap between the seat and the backrest and connected to the winding assembly. Then, the winding assembly in the four bearing plates 6 is turned to tighten the straps to ensure the binding strength of the seat cushion and backrest cushion. Finally, the winding is rotated and positioned by the positioning assembly.

[0028] In some technical solutions, reference Figure 1 The winding assembly includes two mounting shafts 7, two winding shafts 8, two connecting holes 9, two positioning sleeves 10, and several positioning holes 11.

[0029] Two mounting shafts 7 are movably embedded in four bearing plates 6 at both ends. Two take-up shafts 8 are respectively installed on the upper ends of the two mounting shafts 7. Two connecting holes 9 are respectively opened at the center of the two mounting shafts 7 and the two take-up shafts 8. Two positioning sleeves 10 are respectively installed on the outer side of the two mounting shafts 7. Several positioning holes 11 are respectively opened on the side wall of the two positioning sleeves 10.

[0030] In this technical solution, when connecting the straps of the seat cushion and the backrest cushion, one end of the strap is inserted into the connecting hole 9 at the upper end of the winding shaft 8, and then the two mounting shafts 7 in the four bearing plates 6 are rotated to make the straps wrap around the upper end of the winding shaft 8. The straps are connected and wound up by the friction between the straps, thus achieving the purpose of connecting the straps.

[0031] In some technical solutions, reference Figure 1 The positioning assembly includes two fixing sleeves 12, two mounting sleeves 13, two positioning rods 14, and two springs 15;

[0032] Two fixed sleeves 12 are respectively installed on both sides of the lower end of the mounting plate 5, two mounting sleeves 13 are respectively installed inside the two fixed sleeves 12, one end of each of the two positioning rods 14 is movably embedded in the two mounting sleeves 13, two springs 15 are movably embedded in the two mounting sleeves 13, and one end of each spring is in contact with one side of the two positioning rods 14, and the other end of each spring 14 is embedded in one of the two positioning holes 11.

[0033] In this technical solution, after the tightness of the strap is adjusted, the two springs 15 push the two positioning rods 14 to move outward inside the two mounting sleeves 13 until one end of the positioning rod 14 is embedded in the designated positioning hole 11 on the side wall of the positioning sleeve 10. The mounting shaft 7 is rotated and limited by the positioning rod 14. When the mounting shaft 7 needs to be rotated again, the positioning rod 14 can be separated from the positioning hole 11 by turning the handle 16.

[0034] In some technical solutions, reference Figure 1 Both positioning rods 14 are equipped with a lever handle 16 on their lower wall surfaces. An operating nut 17 is installed on the outside of the positioning sleeve. Two fixing rods 18 are provided at the connection between the fixing sleeve 12 and the mounting plate 5. One positioning sleeve 10 corresponds to six positioning holes 11.

[0035] Working principle:

[0036] During installation, the workers first fix the fixing frame 2 to the lower end of the seat body 1 by welding or gluing. Then, one end of the connecting plate 3 is embedded into the fixing frame 2, and the connecting plate 3 is then fixed with fixing bolts 4. Next, the seat cushion and backrest cushion are laid on the seat body 1 and the seat back. The straps of the seat cushion and backrest cushion are passed through the gap between the seat and the backrest, and one end of the strap is inserted into the connecting hole 9 at the upper end of the winding shaft 8. Then, the two mounting shafts 7 in the four bearing plates 6 are rotated to make the straps wrap around the winding shaft. At the upper end of shaft 8, the straps are connected and wound up by the friction between the straps to achieve the purpose of connecting the straps. After the tightness of the straps is adjusted, under the action of the two springs 15, the two positioning rods 14 are pushed to move outward in the two mounting sleeves 13 until one end of the positioning rod 14 is embedded in the designated positioning hole 11 on the side wall of the positioning sleeve 10. The mounting shaft 7 is rotated and limited by the positioning rod 14. When it is necessary to rotate the mounting shaft 7 again, the positioning rod 14 can be separated from the positioning hole 11 by turning the handle 16.
