Description

child seat

technical field

The utility model relates to a child seat, in particular to a child seat that can be used in the field of child seats and can adjust the riding height to provide children with a comfortable ride and a safety protection function to prevent children from falling over or being pinched. seat. the

Background technique

Common child seats are in a fixed form, such as small chairs and low benches, which do not have height-adjustable structures. Therefore, during the growth of children, the sitting posture of children in child seats will change as their height grows, such as thighs. Between the knee joint and the calf, the riding posture with the knee joint as the fulcrum of rotation, the original posture with the soles of the feet on the ground and the thighs parallel to the ground, will cause the thighs to tilt downward from the knees to the buttocks due to the gradual lengthening of the feet, and grow with height , the inclination angle of the thighs will gradually increase, resulting in poor sitting posture and hindering bone development and growth, especially children aged three to seven are in the development stage, and their average height is between 90 cm and 120 cm. Good sitting posture can ensure a correct body and promote Healthy and strong, poor sitting posture will lead to body deformation and endanger growth and development. the

And if a general adult seat is provided for children to ride, then because the adult seat is higher than the child seat, when the child rides, it is very likely that the center of gravity will be unstable due to the shaking of the feet when the child rides. Among the chairs, there is also an adjustable seat structure in which a screw is set under the chair board, and the screw is screwed into the chair frame, and the height of the chair board can be adjusted by screw rotation. The contact parts of the body are pinched, so this kind of seat is not suitable for children in the active period. In addition, the seat structure with multiple legs makes it easy for children to touch or get caught by their feet when walking around it. or get into the range covered by multiple leg tubes due to playing games, resulting in being trapped in the multi-leg tube or being injured by touching and falling over. Therefore, in order to meet the requirements of children riding on When adjusting the height of the seat according to the height of the child, and when adjusting the height of the seat, it is necessary to consider the safety requirements for operation and use, so it is urgent to improve the child seat. the
