A car seat is a piece of safety equipment designed to protect children while they are riding in cars. It is typically installed in a vehicle and consists of a harness or belt that secures the child into the seat, which is then anchored to the vehicle's seats or frame. Car seats are intended for infants, young children, and sometimes older children who require additional safety measures while riding in cars. They help prevent injuries caused by collisions, sudden stops, or other accidents that may occur on the road. The type of car seat required varies depending on factors such as a child's age, weight, and height, so it is important for parents to research and follow safety guidelines when selecting and installing a car seat for their children.
