Emergency Tensioning Devices

(ETDs) and seat belt force limiters
The seat belts are equipped with Emergency
Tensioning Devices and seat belt force limit
ers.
Emergency Tensioning Devices are designed
to activate in the following cases:
• in frontal or rear end impacts exceeding
the system deployment threshold
• if the restraint systems are operational and
functioning correctly
• in collisions with high vehicle deceleration/
acceleration in the longitudinal or lateral
direction, e.g. a head on collision or a side
collision
• on passenger side when the seat is occu
pied and the seat belt is fastened
• in collisions in lateral direction on the side
of the vehicle that is struck
• independently of the front air bags
Occupant safety
When activated, Emergency Tensioning Devic
es remove slack from the seat belts in such a
way that the seat belts fit more snugly against
the body. Seat belt force limiters, when acti
vated, reduce the force exerted by the seat
belts on occupants during a crash.
