Fixed method of front and back of car child safety seat
First of all, we have to understand why there are front and back fixing methods: child seats have four stages: infant type (birth to 13 kg, birth to 18 months), infant type (9-18 kg, about 9 months to 4 One year old), child type (15-36 kg, about 4-12 years old). In the infant type, the baby can bear the load capacity is low, adopting the reverse direction will help protect the baby's head, because the infant type needs to be installed in the direction, the other stages are fixed in the front. The weight of the head of a 1-year-old baby accounts for 25% of the weight of the entire human body. When the vehicle is exposed to the front In a collision, the front-facing fixation will cause the neck to lean forward greatly, passing through the human body The model test result can be obtained when the vehicle speed is 50/H collision, the neck load force is 300KG, and Medical experts suggest that the load on the neck should be less than 130KG. Reverse children in use After the seat, the load on the neck is 80KG, which is beneficial to protect the baby. Can it be fixed on the front seat? I don’t know if you have ever seen the prompt on the vanity mirror in the passenger cabin? The above prompt tells us that the airbag can kill children after exploding, and it can kill 12-year-old children at most. This is not alarmist, just take a look. The tips of your vanity mirror in the passenger cabin explain in detail and you will know why. There are a total of 5 steps to fix the front child safety seat, which is relatively simple to operate. When the seat belt is stretched for a long time, it is easy to be stuck when it is stretched again, so at the beginning, pull out as much as possible, which can facilitate work and avoid insufficient length or the need to re-operate when it is stuck. After confirming that the seat belt buckle is inserted into the interface, we need to check the red fixing clip on the back of the child safety seat. This function is used to fix the seat belt and prevent the seat belt from sliding without fixing the seat. The reverse refers to the child safety seat facing the rear of the vehicle. Because the load force generated by the reverse side has a small effect on the child’s neck, the fixing method of the reverse side of the child safety seat is more suitable for younger children. Relatively speaking, the space for children to ride will also be reduced; when choosing the front and back The decision should be made by the age of the child. (The reverse installation in the figure below is referred to as reverse installation) In reverse installation, you need to pull out all the seat belts and find a way to fix them, otherwise the seat belts will return to position or jam, and you will not be able to install them at this time, so you need to completely pull out the seat belts again. This operation is a waste of time.
