Safety seat is a kind of seat specially designed for children of different weights (or ages), which can effectively improve the safety of children riding. In the case of car collision or sudden deceleration, it can reduce the impact on children and limit their physical activities, thus reducing their injuries.
Safety seat is a kind of seat attached to the car seat, which is an accessory device of the car and has the function of binding protection. The so-called safety seat, child safety seat and child car safety seat all refer to this safety seat. It is a kind of seat only for children, which can restrain children and ensure their safety in the event of a car accident. Its scientific and technological content and value vary from manufacturer to manufacturer. The European enforcement standard ECER44/04 (Netherlands) is defined as a child safety protection system, which can be fixed on motor vehicles and consists of seat belt parts or flexible parts, adjustment mechanism and accessories with ISOFIX interface.
When purchasing safety seats, you can consider the choice of children's seats according to their sex, age and weight:
Babies of different sexes need to use separate safety seats for men and women
Because of the different physiological structures of male and female babies, the five-point seat belt design of traditional safety seats is templated, and male babies will feel uncomfortable when riding. The five-point safety belt of the male safety seat is buckled in front, which reserves more space for the crotch of the male baby; At the same time, the female safety seat buckle inward, which is more suitable for the crotch of the female baby and improves the comfort. ?

According to the age and weight of children, they are divided into four categories:
0+ group: infant type (born to 13 kg, born to1August);
The first group: infants (0- 18kg, newborn to 4 years old);
Group ⅱ: infants (9-36 kg, about 9 months to 12 years old);
Group ⅲ: children (15-36 kg, about 4- 12 years old).
Special attention: children under 9 kg must buy seats that can be reversed, which can protect the baby's head and neck and avoid a strong impact on the baby when braking.
Matters needing attention
Never buy a safety seat without safety certification and safety test.
Do not buy safety seats from unknown sources.
Out-of-stock after-sales warranty, and it takes a long time to allocate parts.
Quality discrimination
One: Judging from the appearance
The main components of children's car safety seat depend on a piece of plastic (adhesive) on the seat back. There are two processes for processing the plastic mould of the chair back: injection molding and blow molding. Blow molding is to put the extruded molten plastic blank into the mold, inflate it with compressed air and attach it to the cavity wall, and then cool and harden it into plastic parts. Injection molding is to use the screw or plunger of the injection machine to inject the molten material in the cylinder into the cavity through the nozzle of the injection machine and the gating system of the mold for solidification. Therefore, the compression resistance and toughness of the injection mold are better.
So how to distinguish between blow-molded and injection-molded seats?
1, intuitive comparison. Blow molded seats are relatively light in weight.
2. Look at the color. Blow molding plastics tend to leave burrs, and the surface smoothness is not as good as that of injection molding. Black can cover up these defects well, so the surface of blow-molded products is mostly black, and generally no other colors will be used.
3. Sensory discrimination. Press the plastic hard with your fingers, and the flexibility of injection molded products is better.
Second: look at comfort.
Closely related to comfort is the material of soft fabric on the seat surface. When choosing a seat, parents should carefully observe how tight the pores of the fabric are, whether it is breathable, and whether it has enough elasticity and toughness. Especially for babies, the breathability and softness of the cushion must be paid attention to.
Three: Look at the safety details.
1, snap design. Seat safety buckle is one of the core components to ensure the safety of children. Many buckles in the domestic market are symmetrical buckles. The disadvantage of this buckle is that it is easy to separate and break. When choosing a seat, parents should pull the button repeatedly to see if it is easy to loosen.
2. Look at the buffer design. The seat of the base and the back cover are connected by a long steel shaft, which can slide in the shaft groove and can be adjusted up and down. The periphery of the shaft groove is not a simple plane design, but a baffle design similar to an accordion. This organ design can be seen in the shaft groove, the edge of the chair back and the skateboard of the base.
3. Design of seat belt connector. When the seat is installed on a vehicle, the seat belt and the seat are fixed and extended by the connector. Qualified seat belt connectors must be smooth to ensure that the seat belt will not be stuck and excessively worn. Qualified seat belt connectors must also ensure sufficient toughness, not too soft or too brittle, and must also ensure that they will not break under the action of fixed seat belts in dangerous situations.
When choosing a safety seat, parents should experience it from the child's point of view to see if it is really safe and comfortable.
