Volvo invented the three-point seat belt 67 years ago; now it has improved it
With the launch of its all-new, all-electric EX60, Volvo has put lessons learned from the EX30 and EX90 to use. The EX60 is built on Volvo's new SPA3 platform, made only for battery-electric vehicles. It boasts up to 400 miles (643 km) of range, with fast-charging capabilities Volvo says add 173 miles (278 km) in 10 minutes. Mega casting reduces the number of parts of the rear floor from 100-plus to one piece crafted of aluminum alloy, reducing complexities and weld points.
Inside the cabin, however, the real achievement is Volvo's new multi-adaptive safety belt. Volvo has a history with the modern three-point safety belt, which was perfected by in-house engineer Nils Bohlin in 1959 before the patent was shared with the world. Today at the Volvo Cars Safety Center lab, at least one brand-new Volvo is crashed every day in the name of science. The goal: to test not just how well its vehicles are protecting passengers but what the next frontier is in safety technology.
Senior Safety Technical Leader Mikael Ljung Aust is a driving behavior specialist with 20 years under his belt at Volvo. He says it's easy to optimize testing toward one person or one test point and come up with a good result. However, both from the behavioral perspective and from physics, people are different. What's not different, he points out, is how people drive.
