In a broad sense, office chairs refer to all chairs used in offices.

[0003] For common office chairs, there are the following technical problems:

[0004] 1. The seat cushion cannot be removed after installation. If you choose a leather seat cushion, you can only accept that it is not breathable in summer and the leather surface is cold in winter. You can choose a wool seat cushion cover to solve the problem in winter, but the problem of airtightness in summer cannot be solved;

[0005] 2. The seat cushion covers of some office chairs are tied to the office chairs with ropes. There are many types of seat cushion covers: cool mat types for summer and plush types for winter. However, the seat cushion covers are connected to the office desks and chairs with ropes, which are not strong enough. Sudden standing up may cause the ropes to break. In addition, different seat cushion covers also require space for storage, which is more troublesome. Moreover, the seat cushion covers have no ventilation effect. After sitting for a long time, the seat cushion will become hotter and hotter, and even sweating may cause bacteria to grow.

[0016] Beneficial Effects

[0017] The utility model provides a flip-up cushion assembly and an office chair, which have the following beneficial effects:

[0018] (1) This kind of flip-up seat cushion assembly and office chair. In the hot summer, after sitting for a long time in a traditional office chair, the seat cushion is not breathable, which will cause the seat cushion to become hotter and even sweat. In the cold winter, the seat cushion is not warm and will feel "cold" for a period of time after sitting. Both situations are not a good experience for users. The present application sets a flip-up seat cushion assembly, so that the seat cushion can be ventilated in the summer and feel cool when sitting. In the winter, the seat cushion can be flipped over. By setting a heating assembly, the seat cushion can also be heated, and it feels warm when sitting.

[0019] (2) The flip-up seat cushion assembly and the office chair have an antibacterial effect by setting the cool ventilation layer to be made of bamboo fiber, which inhibits the growth of bacteria. A layer of rattan net is put on the outer wall of the cool ventilation layer to protect the bamboo fiber and facilitate ventilation. The inner layer of the thermal insulation and heating layer is filled with latex and the outer layer is plush, making it more comfortable for users to sit on.

[0020] (3) The flip-up seat cushion assembly and office chair can be conveniently fixed with a mounting block in a hot environment. The cooling fan draws outside air into the cavity of the rectangular groove through the first ventilation hole during operation. The air then flows upward through the cavity of the support frame through the cool ventilation layer to cool and ventilate the cool ventilation layer. In a cold environment, the seat cushion can be flipped over and a warm heating layer can be provided to make the user feel soft and warm when sitting. A protective frame is provided with mounting strips and heating wires in the protective frame. The heating wires can heat the air in the cavity of the support frame. The heat is transferred to the warm heating layer through the protective frame to heat the warm heating layer. The user can choose to heat the seat cushion in advance to provide a better experience.
