It solves the problem that the air permeability of the seat cushion affects the comfort of the user. There is room for improvement in the air permeability of existing seat cushions, and the seat cushions generally need to be positioned with bolts during installation. Using a large number of bolts to install the seat cushion and the seat is not only laborious, but also inconvenient to disassemble and use, reducing the flexibility and practicality of the seat cushion.

[0006] The sponge base layer adopts a curved surface design, and the upper surface of the sponge base layer is provided with equally spaced curved grooves which are fixed with glue. The outer surface of the sponge base layer is covered with a canvas layer, and when the canvas layer covers the sponge base layer, it is fixed together with the curved grooves.

[0007] Through the above scheme, since the air permeability of the seat cushion will affect the comfort of the user, there is a certain room for improvement in the air permeability of the existing seat cushion, and the seat cushion generally needs to be positioned with bolts during installation. Using a large number of bolts to install the seat cushion and the seat is not only laborious, but also inconvenient to disassemble and use, which reduces the flexibility and practicality of the seat cushion. By providing a curved groove on the upper surface of the sponge base layer, the air permeability of the cushion is optimized, and the rack drives the gear to rotate when moving, so that the threaded rod drives the positioning rod to be retracted and released, which is convenient for installation, positioning or disassembly and maintenance of the cushion.

[0008] Furthermore, the interior of the mounting plate is provided with mounting grooves which are arranged at equal distances, and the outer circumferential surface of the positioning rod is slidably plugged into the mounting plate through the mounting grooves.

[0010] Furthermore, a collar is fixedly connected to the outer circumferential surface of the threaded tube, a cross bar is fixedly connected to the inner wall of the positioning seat, and the inner wall of the collar is slidably sleeved with the outer circumferential surface of the cross bar.

[0011] Through the above solution, the threaded tube is restricted to prevent the threaded tube from rotating following the control rod, thereby increasing the stability of the threaded tube movement.

[0012] Furthermore, a first limiting ring is fixedly sleeved on the outer circumferential surface of the control rod, and the outer circumferential surface of the first limiting ring is rotatably connected to the inside of the positioning seat.

[0015] Through the above solution, the positioning rods on both sides can be moved and retracted in relative directions at the same time, thereby completing the connection positioning of the installation plate or releasing the positioning of the installation plate.

[0016] Furthermore, two second limiting rings are fixedly sleeved on the outer circumferential surface of each of the threaded rods, and the outer circumferential surface of each of the second limiting rings is rotatably connected to the inside of the positioning seat.

[0017] Through the above solution, the threaded rod is restricted to prevent the threaded rod from sliding and deviating, thereby increasing the stability of the threaded rod movement.

[0018] Furthermore, the outer circumferential surface of the positioning rod is fixedly connected to a limiting plate, and the outer surface of the limiting plate is slidably connected to the inside of the positioning seat.

[0019] Through the above solution, the positioning rod is restricted to prevent the positioning rod from rotating along with the threaded rod, so that the positioning rod is always moved laterally.

[0020] Furthermore, a rack is fixedly connected to the outer circumferential surface of the threaded tube, and a gear is fixedly sleeved on the outer circumferential surface of each threaded rod, and the gear is meshed with the rack.

[0021] Through the above scheme, the rack can drive the gear to rotate during the movement, so that the threaded rod drives the positioning rod to be retracted and positioned.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] The breathable cushion optimizes the air permeability of the cushion by arranging curved grooves on the upper surface of the sponge base layer, and drives the gear to rotate when the rack moves, so that the threaded rod drives the positioning rod to be retracted and extended, thereby achieving the effect of improving the air permeability of the cushion and facilitating the installation, positioning or disassembly and maintenance of the cushion, thereby solving the problem that the existing seat cushion has a certain room for improvement in terms of air permeability, and that the use of a large number of bolts to install the seat cushion and the seat is not only laborious, but also inconvenient to disassemble and use, thereby reducing the flexibility and practicality of the seat cushion.

[0043] The curved surface design can improve the comfort of the cushion. The design of the curved groove 2 improves the air permeability of the sponge base layer 1. The mounting plate 13 is connected to the external seat. When the cushion and the seat need to be installed and positioned, the positioning seat 4 can be installed in the mounting plate 13 so that the positioning rod 12 and the mounting groove 14 are aligned. Then, the control rod 5 is rotated to drive the rack 7 to move through the threaded tube 6. The rack 7 drives the threaded rod 11 to rotate through the gear 17. The threaded rod 11 drives the positioning rods 12 on both sides to move toward both sides. The positioning rods 12 are inserted into the mounting groove 14, and then the installation and positioning of the cushion and the seat are completed. When the cushion needs to be removed, it is only necessary to rotate the control rod 5 in the opposite direction to move the positioning rod 12 out of the mounting groove 14 to release the positioning restriction of the cushion and the seat and remove the cushion.
