The child safety seat in car is also called the Child Restraint System (CRS). It is a seat designed for children of different ages (or weight), installed in the car, and can effectively improve the safety of children in the car. The 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 or flexible part with a buckle, an adjustment mechanism, and accessories. It can be combined with additional devices such as a portable crib, baby carrier, auxiliary seat, or collision protection. In the case of a car collision or sudden deceleration, reduce the impact on the child and restrict the child’s body movement to reduce their injury and ensure the safety of the child in the car.


As child safety continues to be valued, in the past 40 years, many different car child seats have been developed to protect child occupants of different heights and ages. At present, the common child seats on the market are divided into infant type, infant type, child booster seat, and all-round type. According to ECER44/03, car child safety seats are divided into five categories according to the weight of the child: Group 0 (applicable to weight less than 10kg); Group 0+ (weight less than 13kg); Group I (weight 9-18kg); Group II (Weight 15-25kg); group Ⅲ (weight 22-36kg).
According to the position on the vehicle, it can be divided into general type; semi-general type; restricted type; special vehicle type. Generally, car child safety seats can be divided into 4 categories according to age, namely: child seats for 0 to 1 years old; child seats for 1 to 4 years old; child seats for 4 to 8 years old; 8 to 12 years old Use a child seat. For different types of child seats, their structure, fixing position, and fixing method on the car are different.
According to the placement direction, car child seats are divided into 1) horizontal, portable crib (baby carrier) belongs to this category, when the baby is lying flat, suitable for babies under 1-year-old; 2) rear-facing, Children ride in the direction of the rear of the vehicle. Children tend to lie down when in use. They are equipped with multi-point safety belts. Most of the products are suitable for children aged 1 to 3 years. When children sit normally, they are generally used in combination with adult seat belts. Most products are suitable for children over 3 years old; 4) Convertible, which can be used both backward and forward, generally suitable for older age groups For children, start to adopt the backward style, and switch to the forward style when the child is tall enough.


There are three main ways to install a car child safety seat. The traditional installation method is to fix the child seat on the rear seat of the car by a car seat belt, as shown in Figure 2. However, in the course of long-term use, people have found that the seat belt fixing method is complicated and there are many misuses. Relevant investigations show that the main reason for the failure of child seats is an insufficient fastening force of seat belts, and about 67% of child seats are installed loosely. At present, the child seat has a special fixing system to fix it more closely to the rear seat of the car. Europe and the United States have separately formulated standards for the way child seats are fixed in the car: the United States is called the LATCH system; Europe is called the ISOFIX system.

LATCH system

(Lower Anchors and Tethers for Children)
According to the regulation FMVSS213, all car rear seat positions must be equipped with child safety seat fixing points, located between the car seat back and the seat cushion. The child safety seat has a connector at the bottom, which can be rigid or deformable, and is used to connect the fixed point of the lower position of the car seat. In addition, the car seat must have an upper fixing point to connect the upper strap of the child seat. The lower fixed point and the upper drawstring form the LATCH system.
The safety system for protecting children can work independently without the safety belt, and the installation of the child seat is very simple, reducing the possibility of incorrect use of the child seat, thereby providing better safety guarantee for the child riding.

ISOFIX system

(InterrationalStardard Organization FIX)
ISOFIX system is a standard fast rigid connection system for car child safety seats formulated by the International Organization for Standardization. The rigid connection between the CRS and the vehicle ensures that the car child seat can be installed correctly under all conditions, regardless of the car seat belt. The ISOFIX international standard fast rigid connection system mainly includes: two rigid fixing points located between the back of the car seat and the cushion, which can combine the baby/child safety seat with the car body; the seat facing forward also has an ” Anti-tilt” fixed point. Unlike the LATCH system, ISOFIX has no mandatory requirements for the upper fixed point, except that the lower connection must be rigid. The ISOFIX standardized child safety seat installation method can reduce the casualties of children aged 0-4 by 22%, especially for the protection of the neck. However, currently, nearly 90% of domestic models do not have ISOFIX devices.

Protection mechanism

Car child safety seats play a great role in reducing the death or serious injury of children in traffic accidents. A survey conducted by NHTSA in the United States shows that from 1975 to 2006, in the United States, child safety seats saved the lives of about 8,325 children; in 2006 alone, child safety seats well protected about 425 children under 5 years of age. Research on the protective effect of child safety seats shows that 71% of infants (under 1-year-old) and 54% of preschool children (1 to 4 years old) have reduced deaths due to the use of child seats. Car child safety seats should protect children’s riding safety under the following conditions:
  • (1) In a forward collision or emergency braking, it can effectively prevent the child’s body from moving forward rapidly, avoiding secondary collisions, and not sliding forward due to poor positioning of the restraint system.
  • (2) In a side collision, the side wings of the backrest and the headrest can effectively protect the torso and head of the child.
  • (3) In a rearward collision, the backrest and headrest can support the torso and head of the child to avoid neck injury.
  • (4) When turning over, the child’s body and restraint system are only slightly displaced and must not be loosened.
  • (5) When the child is sleeping, the side wings of the seat can ensure that the child’s body will not be severely skewed, so as to avoid injury in the collision.

In traffic accidents, a reasonable choice to use car child safety seats can protect children of different ages and heights. The misuse of child safety seats requires people to have a clearer understanding of the types, use, and installation methods of child seats. In addition, the new multifunctional child seat has also become a choice suitable for my country’s national conditions. The use of car child safety seats has not yet been popularized, and the corresponding technical regulations have not yet been implemented. As an emerging research field, the research on child safety seats requires more attention and investment from society. It is believed that in the near future, the safety protection performance of child seats will be more perfect. The scope of application is wider, the installation is more convenient, and child safety seats play a more important role in my country’s automobile safety system. [2]
