[0002] A car child safety seat, also known as a child restraint system, is a seat designed for children of different ages (or weights), installed in a car, and can effectively improve the safety of children riding in a car. In the event of a car collision or sudden deceleration, it reduces the impact force on the child and restricts the child's body movement to reduce their injuries and ensure the child's safety in the car. When in use, the child safety seat is generally fixed to the seat in the car, and support feet are installed at the bottom of the safety seat, which mainly abut against the seat floor and can be retracted and adjusted to provide support. However, the impact force generated by a vehicle collision will act on the support feet, but the support feet do not have a buffering effect, which will transfer a larger impact force upward to the safety seat, posing a safety hazard to the safety seat in which the child is riding.
