Volvo Re-Invents Multi-Adaptive Safety Seat Belts With Smart Tech
Many efforts have been made to improve vehicle safety, particularly with regard to modern technologies such as Advanced Driver Assistance Systems (ADAS). Volvo has made the decision to start over and concentrate on the seat belt, the most important yet fundamental safety item. Volvo invented the three-point seat belt in 1959, and it does not use real-time data to increase the seat belt’s safety features. In 2026, the electric Volvo EX60 will be the first vehicle to use the new multi-adaptive safety belt.
Asa Haglund, head of Volvo Cars Safety Center, says, “The world’s first multi-adaptive safety belt is another milestone for automotive safety and a great example of how we leverage real-time data with the ambition to help save millions of more lives.” “This is a significant improvement over the current three-point safety belt, which was invented by Volvo in 1959 and is thought to have saved over a million lives,” she continued.

Using real-time data input from both external and internal sensors, the new multi-adaptive safety belt may customise protection by changing the settings according to the situation and the profiles of the user, including height, weight, body shape, and seating position. To lessen the chance of a head injury in a catastrophic collision, for instance, a larger occupant will be given a greater belt load setting. A lower belt load setting will be applied to a smaller occupant in a less severe collision in order to lessen the danger of rib fractures.
To do this, the number of so-called load-limiting profile variations—which control the force applied to the occupants in the case of an accident—is greatly increased. Additionally, it improves with time because to over-the-air software updates.

To regulate the amount of force that a modern safety belt delivers to a person’s body in the event of a collision, load limiters are used. By increasing the number of settings and load-limiting profiles from three to eleven, this revolutionary safety belt can optimise performance for any individual and situation.
The new multi-adaptive safety belt may use information from several sensors, such as exterior, interior, and collision sensors, in contrast to conventional systems. The car’s technology quickly analyzes the specifics of a collision, including direction, speed, and passenger posture, and relays that information to the safety belt. The machine chooses the best setting based on this information.
