In the design of child car seats, infants and children before 18Kg (4 years old) generally use a five-point safety belt to protect the human body. This design inspiration is actually derived from the fact that ordinary people have little exposure to aviation. Aerospace seats.
Five-point seat belts, also known as full-body seat belts, are currently widely used in aviation, aerospace, racing, and car seats. It has more restrictive protection for the human body than our ordinary three-point seat belts for automobiles. These areas that have a greater risk of impact on the human body are very popular.
Compared with the three-point seat belt, the five-point seat belt has a crotch point, two points on the waist and two points on the shoulder, a total of five points of constraint, covering the main parts of the human body, so when a strong impact occurs, the same Pressure, the use of five-point seat belts can dissipate in more area of ​​the human body, thereby reducing the pressure at a certain point and reducing the damage of these impacts on the human body.
Because of this, in the design of safety seats, taking into account the immature development of human bones and other human bodies, a five-point seat belt is used to disperse the pressure caused by the impact on all parts of the body, thereby reducing the time of car accidents The impact of the shock on the body of children.
In view of the above introduction, the advantages of the five-point seat belt mainly include the following aspects:
1. The five-point seat belt can dissipate the force generated by the impact in five directions at the same time, and transfer the external force from the child.
Second, the process of dissipating the power of the five-point seat belt is to minimize the accumulation of power and avoid greater harm.
3. The high-performance shoulder pads can effectively absorb the huge impact force, and at the same time, its anti-slip properties reduce the baby's forward and head displacement, to avoid head injuries.
The four- and five-point seat belts can be continuously adjusted according to the baby's body size, thus comprehensively protecting the baby.
5. In the safest state, ensure that the baby has enough space for activity, and at the same time, the baby cannot open the buckle by himself, so that parents can rest assured of the baby's safety.
