Advanced Restraint Systems are a safety technology designed to improve the efficiency of safety items during a crash. A combination of sensors in the cockpit monitor everything from the occupant’s height, the seating position, safety belt usage and the vehicle’s deceleration to control the airbag deployment and the belt forces during a crash. The data gathered from sensors and accelerometers is gathered and provided to a computer which uses this information to decide which safety restraints (belt limiters and multistage airbags) should be deployed and with how much force.
