Seatbelt – No. 1 life saver


Seatbelts are estimated to reduce the overall risk for serious injuries in crashes by 60-70% and the risk for fatalities by about 45%. In rollovers, the risk of fatalities for a belted occupant is reduced by roughly 75%. It is estimated that more than a million people have been saved since seatbelts were first introduced in automobiles in the 1950s. The U.S National Highway Traffic Safety Administration (NHTSA) estimates that in the United States alone, seatbelts save more than 13,000 lives annually, prevent over 300,000 serious personal injuries and save $50 billion every year to the U.S society. 

Seatbelts help reduce the risk of injury in many types of crashes. They help to properly position occupants to maximize the airbag's benefits and --unlike airbags-- they also protect occupants in multiple-collision crashes. Therefore, it is important that seatbelts always be worn, even in airbag-equipped vehicles. 

The seatbelt is designed to stretch at a controlled rate to absorb crash energy and reduce the severity of the occupant's deceleration.

Retractors are stored invisibly at the very bottom of the B-pillar (between the doors) behind the trim. Their job is to pay out the webbing when pulled and block the belt in case of a sudden braking or a crash. 



Buckles are available with sensors to identify whether the occupant is buckled up or not. Other seatbelt components are webbing, pillar loops and fixtures.
As an option, seatbelts may be equipped with Load Limiters that reduce the belt's load on the occupant to a pre-set level to avoid high chest loads. The load limiter normally consists of a torsion bar in the retractor. 
To further reduce the risks, especially if the seatbelt is not correctly positioned on the occupant, Autoliv has developed seatbelt pretensionersactive seatbelts and other innovations. These seatbelt features, as well as load limiters, are also instrumental in Autoliv's integrated systems, where the protective effects from the seatbelt and the airbag are optimally tuned to each other during every phase of a crash.

How to wear the seatbelt

Seatbelts should always be worn with the lap belt low and snug across the hips and the shoulder belt across the chest. Shoulder belts should never be placed under the arm or behind the back. Always try to tighten the belt to remove any slack.











Never drive without!
