Description

Technical Field

[0001] This application relates to the field of automotive technology, and more specifically, to a child safety seat pedal device and an automobile. Background Technology

[0002] Existing child safety seats are special safety seats designed for children's safe travel in cars, preventing significant safety threats to children whose bodies are still developing during emergency braking and collisions. Nowadays, people are increasingly demanding greater comfort from child seats, including requirements for footrests. Many children aged 6-1 years can extend their legs out of the seat, but because their feet cannot touch the car floor and remain dangling in front of the seat, prolonged sitting can cause poor blood circulation due to pressure from the seat cushion on the thighs, leading to numbness in the feet. Simultaneously, the weight of the lower legs and feet can strain the knee joints, causing pain. Therefore, this dangling-feet seating posture significantly reduces the comfort of children traveling in cars. Furthermore, existing child safety seat footrests offer only one angle adjustment and are inconvenient to fold, further reducing user comfort. Therefore, designing a multi-directional adjustable child safety seat footrest to improve children's comfort is a pressing issue that needs to be addressed. Summary of the Invention
