This Ford Technology is more reliable than a regular seat belt as it is designed to provide a higher level of safety to the passengers in the second row outboard seats in the event of a collision, helping to reduce head, neck and chest injuries, especially when the passenger is elderly or a minor, as they are more vulnerable to this type of injury.
The Rear Inflatable Seatbelts work automatically by inflating the belt with cold compressed gas, to contain second row passengers at chest height, at a speed less than an air bag since it is always in contact with the passenger, keeping him in place in the collision event.
