Hyundai Elantra: Seat Belt Pretensioner / Emergency Fastening Device (EFD) Description and Operation
The Emergency Fastening Device (EFD) operates at the same
time with the Seat Belt Pretensioner when it satisifies the deployment
condition after a collision. It is an auxiliary equipment to prevent a
driver and passenger from breaking away by pulling the seat belt toward
the anchor side after a collision. It is located near the anchor on the
driver and passenger seat and is supported by two cables.
