Automotive Driving Belt is a technological marvel compared to the original idea of a fixed-length belt which simply strapped you to the seat. A 21st century seatbelt will allow you flexibility to move around as you need to under normal driving circumstances, but in the event of an accident it will carefully yet very rapidly pull you back into the seat and let you out again if necessary to control how quickly you (and all your internal organs) slow down as the car itself breaks up around you.
The seatbelt and airbags are designed to work very precisely together. Airbags deploy in specific directions, at specific speeds, and the seatbelt makes sure you are held in the right place to benefit from that. There's no point having an airbag go off to absorb your impact if you miss it because you were thrown around the cabin instead. Airbags on American cars are designed to be much bigger and more powerful than on European cars, because fewer Americans wear seatbelts and the airbag has to try and stop an unrestrained occupant instead of a properly-belted one. Thankfully, seatbelt usage in American has improved significantly in recent years, although it still lags behind the rest of the civilised world. In fact, in New Hampshire there is still no law requiring seat belts to be worn!
The automotive industry has made some spectacular technological advances over the last century, but one of the biggest and most important areas of development has been safety. But what makes a 'safe' car?
The broad umbrella of 'safety' is usually divided into two categories: active safety and passive safety. Active safety is the car's ability to avoid having an accident. Passive safety is the car's ability to protect its occupants once it is actually having an accident. For example, anti-lock brakes are an active safety feature, while airbags are a passive safety feature.
