What is the purpose of a tether strap?

A tether strap is designed to secure an object, such as a child safety seat, to a vehicle to prevent it from moving or tipping during an accident or sudden stop. It helps enhance the stability and safety of the seat, ensuring it stays in place and protects the occupant. Tether straps are often used in conjunction with seat belts and are an important part of car seat installation guidelines for optimal safety.
