[0023] The utility model is further described below in conjunction with the accompanying drawings.

[0024] See Figure 1 —— Figure 5The utility model is a chair with an adjustable seat cushion, comprising: a seat cushion 7, a bracket 10, and a backrest 11. The bracket 10 is provided in two groups, a left group and a right group. The backrest 11 is located between the rear parts of the two groups of brackets 10. The bracket 10 is provided with a support rod 2 and a rotating rod 3. The seat cushion 7 is installed on the support rod 2 and the rotating rod 3. The support rod 2 and the rotating rod 3 are parallel to each other. The support rod 2 is mainly used to support the seat cushion 7. The rotating rod 3 is used to support the seat cushion 7 and adjust the position of the seat cushion 7. As shown in the figure, the support rod 2 does not have a connecting hole. Of course, the support rod 2 can also adopt the same structure as the rotating rod 3. The side of the mounting rod 1 is provided with a mounting hole, and the support rod 2 and the rotating rod 3 are connected by a fixing bolt 12.

[0025] The upper end surface of the seat cushion 7 of the utility model is provided with an elastic rope 13 to increase comfort and air permeability. The rear end of the seat cushion 7 is provided with a compression bag 8, which is filled with elastic cotton. The compression bag 8 is made of breathable mesh. The compression bag 8 is in contact with the lower end of the backrest 11. When the seat cushion 7 moves backward, the compression bag 8 is compressed, so it will not block the movement of the seat cushion 7. When the seat cushion 7 moves forward, the elastic cotton is reset and can maintain contact with the lower end of the backrest 11 without a gap, thereby maintaining the overall aesthetics.

[0026] See Figure 2 The rotating rod 3 of the utility model is in a straight line shape, and a main hole 5 is opened in the middle of it. The middle of the rotating rod 3 extends outward to form a support part 4, and the support part 4 has a support hole 6. The main hole 5 and the support hole 6 are both located on the central axis of the support part 4. The rotating rod 3 and the support part 4 can support the seat cushion 7. When the seat cushion 7 is adjusted forward and backward, it can be quickly adjusted through the main hole 5 and the support hole 6. There are threaded holes 9 on both sides of the rotating rod 3, which can be fixedly installed on the mounting rod 1 of the chair by fixing bolts 12.

[0027] The seat cushion 7 of the present invention has a connecting hole at the bottom, which is respectively connected to the adjusting bolts passing through the main hole 5 and the supporting hole 6. Only one connecting hole needs to be opened, and only one adjusting bolt is needed. The structure is very simple and the adjustment is very convenient.

[0028] See Figure 3 The support part 4 of the utility model is located at the rear of the rotating rod 3 and connected to the mounting hole of the cushion 7 through the main hole 5. At this time, the compression bag 8 is squeezed more by the backrest 11. The size of the backrest 11 and the front end of the cushion 7 is shorter. This installation method is suitable for people with shorter legs and shorter height, such as people with a height of less than 1.5 meters.

[0029] See Figure 4 The support part 4 of the utility model is located at the rear or front of the rotating rod 3, and is connected to the mounting hole of the seat cushion 7 through the support hole 6. At this time, the compression bag 8 is less squeezed by the backrest 11. The size of the backrest 11 and the front end of the seat cushion 7 is average. This installation method is suitable for people with average legs and average height, such as people with a height of 1.5-1.8 meters.
