AI Technical Summary

Problems solved by technology

[0003] Messenger-type three-point seat belts still have the disadvantages of not being able to disperse the impact force evenly according to the standard weight for adults, but for children, the impact force is large, and the child is not tall enough, so it is easy to strangle the neck and protect the shoulders of the human body.

[0004] Vehicle-mounted child safety seats generally adopt an external form. Due to the small space in the car, the external child safety seat takes up a lot of space in the car, and it is troublesome to install and disassemble, and it is not easy to clean. It also hinders the normal use and maintenance of the car rear seat. Use of space in the trunk

[0005] The car booster pad is actually like a cushion, mainly to increase the child's sitting height so that children and adults can use car seat belts to travel in cars. Car seat belts can't disperse the impact according to the height and weight of adults, let alone children, and The tension of the webbing exceeds the standard range of the child's tolerance, which will cause secondary damage to the child's body, and the car seat belt, that is, the three-point seat belt, has defects such as less protection for the human body's shoulders and head.

[0006] Vehicle-mounted child safety seats generally adopt an external form. Due to the small space in the car, the external child safety seat takes up a lot of space in the car, and it is troublesome to install and disassemble, and it is not easy to clean. It also hinders the normal use and maintenance of the car rear seat. The use of space in the trunk, the safety seat completely restrains the child in the limited space, which limits the freedom of the child and reduces the comfort of the child. Moreover, the plastic on the side of most safety seats on the market is relatively hard, which is prone to accidents. accidental injury to children
