Seat Belt Pretensioner Hyundai Santa Fe III

Passive Restraints 10 illustrations ~669 words

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.

CAUTIONNever 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.

The Emergency Fastening Device (EFD) operates as well as the belt pretensioner at the same time, if it gets into its deploy condition after a collision. It is located near the anchor on the front seat and it is an equipment to make up for the existing short stroke. The front seat belt EFD is an auxiliary equipment to prevent the driver and passenger from breaking away doubly as the seat belt is pulled towards the anchor side after a collision.

CAUTIONNever measure resistance of EFD directly, current of measuring device may cause unexpected airbag deploy.
