Components

1. Seat Belt Pretensioner (BPT)

Seat Belt Pretensioner (BPT) Description and Operation

Description

The Seat Belt Pretensioners (BPT) are installed inside Center Pillar (LH & RH). When a vehicle crashes with a certain degree of frontal impact, the pretensioner seat belt helps to reduce the severity of injury to the front seat occupants by retracting the seat belt webbing. This prevents the front occupants from thrusting forward and hitting the steering wheel or the instrument panel when the vehicle crashes.

(Seat belt pretensioner may be activated in side impact collisions if the vehicle has side airbag or curtain airbag.)

• Never attempt to measure the circuit resistance of the Seat Belt Pretensioner (BPT) even if you are using the specified tester. If the circuit resistance is measured with a tester, the pretensioner will be ignited accidentally. This will result in serious personal injury.

Emergency Fastening Device (EFD) Components and Components Location

Components

1. EFD(Emergency Fastening Device) System

Emergency Fastening Device (EFD) Description and Operation

Description

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.

• Never measure the resistance of the anchor pretensioner directly, the current of the measuring device may cause unexpected airbag deploy.
