ZF has introduced a new seat belt system which ‘adjusts’ occupants into an optimal seating position before a potential collision.
Equipped with sensors, the system responds promptly to potential hazards.
The core is the ACR8 electromechanical belt tensioner which reduces belt slack and can alert the driver through vibrating the belt.
During a crash, the seat belt and airbag work in tandem as protective systems. The seat belt restrains the upper body initially, and then releases, guiding the occupant towards the airbag.
For driving situations, such as hard braking or potential collisions, the system is connected to vehicle sensors and the automatic emergency brake assistant. It then adjusts the occupant’s position, holding them securely during the braking manoeuvre, bolstering their protection.
The ACR8 system also acts as a haptic signal transmitter to alert the occupant. It can send signals to awaken drivers, if the system detects signs of fatigue, and uses high frequency pulsing to prompt the driver to take control when switching between automated and manual driving.
Automakers can opt for a seat integrated version requiring only a 60mm installation depth instead of 82mm.
