Description

Technical Field

[0001] The present invention relates to the technical field of child seats, and in particular to a side protection structure for a child seat and an adjustment method thereof. Background Art

[0002] A child seat, also known as a child restraint system, is a seat designed for children of different ages (or weights) and installed in a car to effectively improve the safety of children riding in a car. European regulation ECE R44 / 03 defines a child safety seat as: a child safety protection system that can be fixed to a motor vehicle and consists of a seat belt assembly with buckles or flexible components, adjustment mechanisms, accessories, etc. It can be combined with additional devices such as a portable crib, infant carrier, booster seat or collision protection. In the event of a car collision or sudden deceleration, it reduces the impact force on the child and restricts the child's body movement to reduce their injuries and ensure their safety.

[0003] Most traditional child seats do not have adjustable side protection structures. When the vehicle turns sharply while driving, the seat will cause it to tilt left or right and generate impact force. Children sitting in the seat may bump into the seat and cause injury. Therefore, there is an urgent need for a retractable and adjustable side protection structure to be used in child seats to effectively and efficiently absorb vibration and energy, reduce impact force and protect children. Summary of the Invention
