Press, Car seat is a seat that is attached to the seat of a car for children to ride and to restrain children in the event of a car accident. According to Article 4 of the "Implementation and Advocacy Measures for Safe Carriage for Young Children with Small Cars", when a small car is attached to a road, the young child should be placed in a safety chair in the following manner: 1. Under the age of 1 or Infants under the weight of 10 kg should be placed in the back seat of the vehicle for infants in bed or rear seat for young children to be restrained or positioned. 2. Those who are over 1 year old and under 4 years of age and weigh from 10 kg to 18 kg should sit in the seat of the child in the back seat of the vehicle and restrain or position them. 3. Each safety chair is limited to a young child, and the safety chair and the car seat should be firmly connected according to the instructions in the instructions attached to the safety chair product. The first child safety chair use regulations, such as the child's body type can not be used according to the specified user, you must use the appropriate safety chair. Children over the age of 4 to 12 or weighing between 18 kg and 36 kg should sit in the back seat of the vehicle and use seat belts in accordance with the driver's and passenger's seat belt implementation and publicity guidelines.

However, the conventional car safety seat, such as the "Children's Safety Seat Auxiliary Fixing Belt" of the Republic of China Patent No. M259729, is provided with an adjusting belt and two side belts; the side belt has a positioning plate at one end and another One end is coupled with a female buckle; the adjusting belt is provided with a male buckle at both ends and is formed with a belt loop; thereby, the adjusting belt is passed through the wearing hole on both sides of the safety seat, and the male buckle at both ends is inserted The side buckle of the side belt, and then the belt to pull the belt to adjust the length of the adjustment belt, so that the safety seat is fixed on the car seat; however, the car travels to the left and right because of the turn, and accelerates or rushes in the car When the vehicle is braked, the safety seat will be upside down, and the child seated in the safety seat will be uneasy due to the ups and downs.

The utility model also provides a "full-coverage lightweight child safety seat" such as the Republic of China Patent Certificate No. M422503, which is a body formed by a foamed material, which is completely coated on the first hard layer. Between the second hard layer and the second hard layer; thereby, the body can be shock-absorbing or buffered; however, although the body can be shock-absorbing or buffered, the car travels to the left and right due to the turn, and accelerates or rushes in the car. When the vehicle is braked, when the moment is greatly reversed, the body only has limited shock absorption or buffering, which may cause the child lying in the safety seat to be scared and panic.
