Background
Present safety seat is generally used, and when the vehicle collided, supplementary restraint system can absorb partly energy effectively, fixes children in safety seat to the effectual condition of having avoided children to throw away safety seat. In the event of a frontal collision, the injury to the child in the collision is significantly reduced.
The latest European automobile collision safety standard ECE R129 regulation is completely implemented from 2018, new requirements on the limit of the abdominal pressure of children are made in the new regulation, the current collision safety regulation in China refers to the European ECE R44 standard, and the ECE R129 is also certainly referred to in the future to make corresponding updates. When the automobile is in a frontal collision, the impact force applied to a child passenger is about 20 to 30 times of the weight of the child passenger, and all the impact force is finally absorbed by the restraint system and fed back to the child, so that the method for uniformly dispersing the impact force in the collision to the whole body of the child is an effective way for relieving the injury of the child passenger. By means of auxiliary restraint, a part of energy is absorbed by the shoulder and the elastic device when collision happens, and injury to a child passenger is reduced effectively.
The main types of child safety seats currently on the market are the five-point harness restraint and the front body restraint. When the impact force is too large, the safety belt restrains the chest of the child to generate large extrusion force, and the body of the child is easily injured. Aiming at the front protection body type child safety seat, the design of the front protection body type child safety seat considers the comfort requirement of a child, the lower part of the front protection body is usually made into a concave shape adapting to the shape of a leg, and the defect of the prior art is that a gap exists between the protection body and the leg, so that the phenomenon that the child winds the front protection body when the child collides greatly is generated, even the situation that the child is thrown out of the seat is generated, and the casualties of the child passengers are caused to different degrees.
