The seatbelt reduces fatality by 45%.
Seatbelts
Seatbelts are designed to secure the occupants of a vehicle against harmful movement during a collision or a sudden stop. Seatbelts are considered the primary restraint system, because of their vital role in occupant safety, and can reduce the overall risk of serious injuries by 60%.
Top life-saving device
Working together with airbags in a collision, the seatbelt provides occupants with an added sense of safety and can guard from potential further injury. The Autoliv seatbelt systems work together to save more lives: retractors, buckles, load limiters, pretensioners, pre-pretensioners, hardware and active seatbelts.
Retractors
The seatbelt material (known as webbing) is housed in a rotating spool called a retractor, a highly designed mechanical product that Autoliv considers to be a hidden yet important part of its safety systems. As an occupant reaches for the seatbelt to initiate the buckling-up process, the retractor releases webbing to provide comfort to the occupant. The retractor's sensors can tighten up or release webbing in the event of a collision.
Better belts: Pre-pretensioner mechatronic integration (PPMI)
The Pre-pretensioner mechatronic integration offers ideal occupant positioning with reduced pre-crash excursion, prevents belt slack before crash and secures effective ADAS warnings. The Pre-pretensioner can also reduce chest deflection in a crash. The PPMI can support effective haptic warning functions, for example the lane departure warning functionality.
