The traditional installation method involves securing the child seat to the rear seat of the car using the vehicle's seat belt. However, over long-term use, it has been found that the seat belt fixing method is complex and prone to misuse. 2. The United States has established a standard for securing child seats in vehicles, known as the LATCH system. 3. Europe has developed a standard for securing child seats in vehicles, called the ISOFIX system. Classification of child seats: 1. Infant type. 2. Infant and toddler type. 3.
