  • Volvo's innovation uses sensors to help the belt adjust its load
  • The company claims it can help reduce injuries
  • The multi-adaptive safety belt will feature on the EX60

Volvo can claim to be part of the very history of the humble seatbelt, considering Swedish engineer and Volvo employee Nils Bohlin perfected his three-point harness with the company way back in the late 1950s.

Now, it wants to inject some serious smarts into a very simple device that has saved millions of lives over the years.

Thanks to input from the multitude of sensors, cameras, and compute tech onboard the upcoming EX60 (the EX90's sleek little brother), Volvo’s new multi-adaptive safety belt can provide the perfect tension in the unfortunate event of an accident.

Most regular seat belts have three “load-limiting” profile variations that help apply the right load for drivers and occupants of differing heights and weights.

However, Volvo’s latest invention features 11 profiles that adapt to traffic variations and the person wearing it, thanks to real-time data from the car’s advanced sensors, according to the Swedish marque.

Sensors inside can detect height, weight, and seating position of occupants, while the exterior sensor suite can analyze the characteristics of a crash and send the data to the belt to provide the appropriate load "in the blink of an eye".

And how will it help? Well, Volvo gives the example that larger occupants in a serious crash will receive a higher belt load, while smaller occupants in a less severe crash will receive a milder load to prevent common injuries associated with standard seat belts.
