Volvo is looking to boost its reputation for safety with the release of a new “multi-adaptive safety belt” that uses real-time data from the vehicle’s sensors to better protect the person wearing it.
Seatbelt technology hasn’t changed much since Volvo patented one of the first modern three-point safety belts in the early 1960s. But cars have changed significantly, adding sensors, cameras, and high-powered computers to power advanced driver assist features and anti-crash technology.
Now, Volvo wants to put those gadgets to work for seatbelts. Modern safety belts use load limiters to control how much force the safety belt applies on the human body during a crash. Volvo says its new safety belt expands the load-limiting profiles from three to 11 and increases the possible number of settings, enabling it to tailor its performance to specific situations and individuals.
As such, Volvo can use sensor data to customize seatbelts based on a person’s height, weight, body shape, and seating position. A larger occupant, for example, would receive a higher belt load setting to help reduce the risk of a head injury in a crash, while a smaller person in a milder crash would receive a lower belt load setting to reduce the risk of rib fractures.
During a crash, Volvo says its vehicles’ safety systems will share sensor data — such as direction, speed, and passenger posture — with multi-adaptive seatbelts to determine how much force to apply to the occupant’s body. And using over-the-air software updates, Volvo promises that the seatbelts can improve over time.
Volvo has previously deviated from traditional practices to introduce new technologies meant to underscore its commitment to safety. The company limits the top speed on all of its vehicles to 112 mph — notably below the 155 mph established by a “gentleman’s agreement” between Mercedes-Benz, Audi, and BMW to reduce the number of fatalities on the Autobahn.
The new seatbelts will debut in the Volvo EX60, the automaker’s mid-sized electric SUV which is scheduled to come out next year.
