The importance of seatbelts in vehicle safety can not be ignored. Over the yeas, innovations have been introduced to make seatbelts more efficient and convenient for vehicle occupants. New seatbelt designs and technologies are now being developed by a number of companies and automakers. Many automakers are working on seatbelts that are attached to the seats instead of the side or ceiling of the car as in conventional seatbelts. However, this type of seatbelts may not be convenient for rear-seat passengers than front-seat occupants.

Some automakers are also developing seatbelts that amp up the level of protection by automatically tightening as soon as it detects pressure on the brakes in the event of an impending crash. This ensures that the passenger is properly restrained in case of crash. Another seatbelt innovation still in the works is a rear-seatbelt warning system that inflates on impact.

Another high-tech innovation in seatbelts is a built in breathalyzer system that is linked to the car’s starter. Apparently, the car will not start if the breathalyzer detects a high alcohol content level in the driver. Still, this integrated breathalyzer must comply with varying state DUI laws. These new designs will be offered either as standard equipment or part of a safety options package.

Among the current models featuring seat-integrated seatbelts include the 2007 Honda Element, Saab 9-3 convertibles, Mercedes CL-, SL-class. The Infiniti Q45, M35, and M45 also offer electronic sensor system. The rear-seat shoulder belts in the new Ford Reflex concept feature air bags. Meanwhile, Volvo is developing an integrated breathalyzer and seat-belt system called Alcolock.
