The term "seatbelt" which is often used while driving, refers to a safety restraint device that helps to secure the occupants of the car. However, there are many other names in which seatbelts are known such as safety belt, harness, seat strap, and lap belt. The term "safety belt" is the most commonly used synonym for seatbelt. A harness is another type of restraint that secures the driver and passengers in a vehicle, whereas a seat strap and lap belt focus on connecting the seat and the person to the car.
