The child car seat with the integrated overheating protection for children provides a solution for the problem of overheating children, which may occur if the child is forgotten in a car, where the sun and other external influences may cause the child to overheat. The child car seat with the integrated overheating protection for children has an integrated temperature sensor, which, at elevated temperatures inside the car, and adjustable through the temperature button, triggers an audible alarm warning, which transmits sound or recorded messages stored in the processor. A certain amount of time after the elevated temperatures have been detected by the temperature sensor, the processor opens a valve, which begins to controllably release water from the water storage container and so begins the cooling-off phase of the child. After the system of the child car seat with the integrated overheating protection for children has been activated, we can dry the seat and refill it with water through the valve so it is ready to be used again.
