Referring to fig. 1 to 6, the child seat of the present invention has a child seat airbag, which includes a gas generator 1, an air guide structure 4 and an air bag 3. One end of the gas guide structure 4 is connected with the gas generator, the other end of the gas guide structure extends into the gas bag 3, and a plurality of gas guide holes 5 are formed in one end, extending into the gas bag 3, of the gas guide structure 4. The air guide holes 5 play a role in guiding and buffering gas pressure, the number, size and position of the air guide holes 5 are designed according to protection requirements, and the length of the air guide structure 4 is designed according to protection requirements. One end of the gas guide structure 4 wraps the gas outlet 2 of the gas generator, and the gas generator 1 is fixedly sealed by a metal hoop 8. The gas generator 1, the gas guide 4 and the gas sack 3 are fastened by means of a metal bracket 8 and at the same time have the function of sealing the gas, so that the gas of the gas generator 1 can be completely filled into the gas sack 3 via the gas guide 4. The air guide structure 4 is made of a flexible material, and the flexible material comprises cloth.

The gas generator 1 in this embodiment is located the child seat base 11, and the gas generator 1 is together fixed with the child seat base 11, and the regional children's buttock is avoided in gas generator 2 position, and it is located the dog 13 below region, and the gas generator 1 receives the collision signal after the ignition and produce a large amount of gas rapidly.

When the bag 3 is inflated, the upper portion of the bag 3 forms an upper protection portion 3a for protecting the head and neck of the child, and the middle-lower portion of the bag 3 forms a middle-lower protection portion 3b for protecting the chest and abdomen of the child. The upper protection part 3a is of an outer convex arc-shaped surface structure, and the middle and lower protection parts 3b are of an inner concave arc-shaped surface structure. The air bag 3 in this embodiment encloses the air guide 4 and the gas generator 1, the air bag 3 extending from the seat cushion 12 of the child seat and then into the stop 13.
