Detailed Description

The invention will be further described with reference to the accompanying drawings in which:

as shown in fig. 1, the novel seat comprises a seat surface 1, a seat body support 2 for supporting the seat surface 1, and a backrest 3 connected to the seat body support 2. The seat 1 comprises a frame body 11 connected with the seat support 2, two rotating shafts 12 connected in the frame body 11, and a ring-shaped bearing belt 13 connected between the adjacent rotating shafts 12 for bearing the weight of the human body. The frame body 11 is connected with a motor for driving the rotating shaft 12 to rotate and a switch for controlling the motor to operate. The motor is controlled to operate through the switch, the motor drives the rotating shaft 12 to rotate, and then the annular bearing belt 13 on the rotating shaft 12 is driven to move, so that the chair surface 1 is replaced, and the structure is simple and the operation is convenient.

Preferably, the distance between the frame body 11 and the ring-shaped carrier belt 13 is 2-3 cm. And an electric fan used for blowing the area of the annular bearing belt 13 is arranged on the seat body support 2. The side which is not supported by the annular bearing belt 13 can be cooled through the arrangement of the electric fan, and meanwhile, the air circulation of the gap between the frame body 11 and the annular bearing belt 13 can be increased, which is beneficial to cooling the chair seat 11. The ring-shaped carrying belt 13 is made of at least two materials, so that a user can freely select the comfort requirements of the chair surface 11 such as temperature, hardness and the like.
