Seatbelt tensioner during collision
All the seatbelts are equipped with a pyrotechnic seatbelt tensioner.
The pyrotechnic seatbelt tensioner tensions the seatbelt in the event of a collision with sufficient force in order to more effectively restrain the occupant.
Seatbelt tensioner during critical situations
The driver and front passenger seatbelts are equipped with an electric seatbelt tensioner.
The seatbelt tensioners work together and can be activated together with the driver support systems City Safety and Rear Collision Warning. In critical situations, such as panic braking, sharp evasive action, driving off the road (e.g. the car rolls over into a ditch, lifts off the ground or hits some off-road object), skidding, or risk of collision, the seatbelt can be tensioned by the seatbelt tensioner's electric motor.
The electric seatbelt tensioner adjusts the occupant to a better position, reducing the risk of striking the car's interior and improving the effect of safety systems, such as the car's airbags.
Resetting the electric seatbelt tensioner
Once the critical situation has passed, the seatbelt and electric seatbelt tensioner are reset automatically.
Never modify or repair the seatbelts yourself. Volvo recommends that an authorised Volvo workshop should be contacted.
If the seatbelt has been subjected to a major load, such as in conjunction with a collision, the entire seatbelt must be replaced. Some of the seatbelt's protective properties may have been lost even if the seatbelt does not appear damaged. The seatbelt must also be replaced if it shows signs of wear or damage. The new seatbelt must be type-approved and designed for installation at the same location as the replaced seatbelt.
