Volvo just reinvented the seatbelt, and this is why it matters to you

Car changing is a big deal
Volvo’s new seatbelt adapts to your body and the crash before it happens. Consumer writer Siobhan Doyle speaks to the safety experts behind this game-changing tech.
For over six decades, seatbelts have done one thing exceptionally well: holding you in place when everything goes wrong. But what if a seatbelt could also understand you – your body, your posture, even the kind of crash unfolding – and respond accordingly, all before impact?
That’s the idea behind Volvo’s new multi-adaptive safety belt, a world-first technology debuting in the new fully electric Volvo EX60. It represents the biggest reimagining of the seatbelt since Volvo introduced the three-point design in 1959 – a breakthrough that has helped save countless lives worldwide.
“This is a major upgrade to the modern seatbelt,” says Åsa Haglund, head of Volvo Cars’ Safety Centre. “By using real-time data, we’re moving from one-size-fits-all safety to something more personal, and more effective.”
I spoke with Volvo safety experts – Fredrik Heurlin, technical specialist in Protective Safety Applications, and Lotta Jakobsson, senior technical specialist in Injury Prevention – to find out how Volvo’s new technology was developed and how it keeps you safe.

Why one size never fits all
Car safety has traditionally been built around averages: the average adult body, the average crash, the average seating position. But in the real world, no two occupants – or collisions – are alike.
For instance, a larger adult in a high-speed crash may need a stronger belt load to reduce head injuries. Meanwhile, a smaller person in a low-severity collision may need less force to avoid rib fractures. The problem is that today’s seatbelts can’t tell the difference.
Volvo’s multi-adaptive safety belt is designed to change that.
“The system is built on the understanding that safety outcomes depend on who is in the seat and what kind of crash is happening,” Heurlin and Jakobsson tell Carwow. “The belt adapts its response to both.”
A seatbelt that reads the situation
So, how does it work? In the moments leading up to a collision, the multi-adaptive belt draws on data from the car’s interior and exterior sensors, analysing:
- Crash direction and severity
- Vehicle speed and impact
- Occupant size, posture, and seating position
“In less than a blink of an eye, the system selects the belt setting best suited to the specific combination of crash characteristics, occupant, and seating position at the moment of impact,” the safety experts say.
The result isn’t just tighter restraint – it’s smarter restraint.
From three profiles to eleven
At the heart of the technology is a major technical leap. Most modern seatbelts offer up to three load-limiting profiles, which control how much force the belt applies to the chest during a crash. Volvo’s new system expands that to eleven profiles.
The technical specialists say this dramatically increases precision: “The increased number of load-limiting profiles variants allows the belt to manage force more precisely depending on the individual and the crash scenario. It enables better tailoring of protection.”
In practice, a forward-leaning passenger in a moderate crash may get gentler tension to protect the chest, while an upright passenger in a high-speed collision may receive firmer restraint to control torso movement and reduce spinal risk.
Built on over 50 years of real crashes
The multi-adaptive safety belt isn’t theoretical. It’s built on over 50 years of Volvo safety research and lessons learned from more than 80,000 real-world crashes.
“That unique safety knowledge has directly informed the system’s design,” Heurlin and Jakobsson say.
The belt has been tested both physically and virtually in Volvo’s Safety Centre crash lab in Sweden, where engineers can recreate nearly any real-world crash scenario.
“Our crash lab allows us to refine the system across a huge range of scenarios – not just the ones regulators test for, but the ones people actually experience,” the technical specialists note.
No set-up means no guesswork
Heurlin and Jakobsson tell Carwow that, despite its sophistication, the system requires no input from drivers or passengers. “Occupants don’t need to enter information like height or weight,” they say. “The car’s sensors figure out who’s in the seat, how they’re sitting, and what kind of crash might happen, then adjust the belt automatically.”
Comfort stays simple, too: you can still move the shoulder belt up or down as usual, while the safety system works on its own. It works the same way for kids in booster seats, automatically choosing the best settings for them.
A seatbelt that evolves
Perhaps the most surprising thing about this seatbelt is that it doesn’t stop improving once the car leaves the factory. The multi-adaptive belt can get smarter through over-the-air updates, learning from new data to fine-tune how it protects you, Heurlin and Jakobsson add.
“As we gain new insights, the car can improve its understanding of occupants and crash scenarios,” they add. “That allows the belt to get better over time.”
It’s a move from regular, fixed safety features to a system that learns and improves as you drive.
Looking beyond regulations
The system has been developed to Volvo’s Safety Standard, which exceeds many regulatory requirements. While independent ratings such as Euro NCAP haven’t yet been published for the EX60, Heurlin and Jakobsson expect the multi-adaptive belt to play a key role in overall safety performance.
For a company that once gave away the patent for the three-point seatbelt because lives mattered more than profit, the philosophy hasn’t changed – only the tech has. The original three-point seatbelt made automotive safety universal. And Volvo’s new multi-adaptive belt takes the next step, making protection personal.
In a future where cars can see, predict, and respond in real time, the humble seatbelt is no longer just a strap across your chest. It’s an intelligent system, quietly working to protect you – before you even know you need it.
For Volvo, this may be the most meaningful safety innovation since 1959.
