AI Technical Summary
Existing child seat seat belt buckles are prone to loosening or falling off when violently shaking or emergency braking, and the thinner seat belts put pressure on the children's waist, causing children to be unwilling to use safety seats.
A seat belt buckle for child seats is designed, including waist belt guards, reinforced connecting belts, first and second connecting belts, first and second connecting belts, first and second buckle blocks, movable plates, clamps, knobs and bolts, etc. Through the synergistic effect of these components, a stronger support and fixing force is achieved, and through the arrangement of breathable holes, vibrators and connecting belts, the pressure on the body is reduced and the comfort is improved.
It provides firmer support and stronger fixation force to ensure that the seat belt will not be unscrewed in unexpected situations. At the same time, the setting of breathable holes and vibrators keeps the belt dry and comfortable, reduces the feeling of pressure on the children's waist, and increases the willingness of children to use safety seats.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of safety belts, and more specifically to a safety belt buckle for a child seat. Background Art
[0002] A child seat, also known as a child safety seat, is a seat device designed for children and installed inside a car to improve the safety of children when riding in a car. It provides a comfortable and safe riding environment for children through special structures and materials combined with ergonomic principles. In the event of a vehicle collision or sudden deceleration, a child seat can effectively mitigate the impact force and limit the movement of the child's body, thereby significantly reducing the risk of injury to the child. The design of a child seat takes into account the child's age, weight and height to ensure that children at different stages can be properly protected. Using a child seat is one of the important measures to ensure the safety of children riding in a car.
[0003] The shortcomings of existing child seat safety belt buckles:
[0004] First, the existing seat belt buckle only fixes the seat belt through the sub-buckle and the main buckle when in use. When there is a violent shake or emergency braking, the seat belt buckle will loosen or fall off, thus affecting its protective effect on children.
[0005] Second, existing child safety belts are relatively thin and put greater pressure on the child's waist when in use, which may cause children to resist the safety seat and be unwilling to sit on it. This may reduce children's willingness to use safety seats when riding in a car, thereby increasing their safety risks. Utility Model Content
