The technical scheme adopted by the invention for solving the technical problems is as follows: the multifunctional chair comprises a chair seat, a chair back and supporting legs, wherein the chair seat comprises a fixed chair seat and a movable chair seat, the supporting legs are of a frame structure, the lower end of the fixed chair seat is connected with the upper ends of the supporting legs, one end of the movable chair seat is hinged with one end of the fixed chair seat, and the lower end surface of the movable chair seat can be in contact connection with the upper end surfaces of the supporting legs; the back of the chair is including fixed back of the chair and activity back of the chair, and fixed back of the chair lower extreme is kept away from articulated one end with fixed seat support and is connected, and the link on fixed back of the chair upper portion is "nearly" font structure, and the lower extreme of the activity back of the chair is provided with the inverted U-shaped opening of adaptation, and the terminal surface of opening both sides is articulated with fixed back of the chair link both sides shoulder upper end, and the activity back of the chair rotates downwards, can make activity back of the chair.

Wherein, the back side of the movable chair back in the device is provided with a groove.

Wherein, the lower part of the chair seat in the device is provided with a supporting plate, and the outer side of the supporting plate is connected with the supporting legs.

Wherein, in the device, the fixed seat and the fixed chair back are integrally formed.

The invention has the beneficial effects that: the device comprises a seat and a chair back which are both formed by two hinged plates, and the upper end of the fixed chair back at the lower part is of a structure like a Chinese character 'ji', so that the lower end of the movable chair back at the upper part is provided with an inverted U-shaped opening. When the infant seat is actually used, the movable seat can be upwards folded by 180 degrees, an infant can be directly placed on the folded seat, and the movable seat back is downwards rotated by 90 degrees, so that the infant can be fixed. The back side of the movable chair back is a dining area for children, and the groove area is designed on the movable chair back, so that food or toys are effectively prevented from being scattered. The device can change an adult chair into a child dining chair, so that the functions of the chair are increased, and the number of people using the chair is increased.
