Hyundai Accent: Seat Belt Pretensioner (BPT). Description and Operation
Hyundai Accent RB (2010-2018) Service Manual / Restraint (Depowered) / Seat Belt Pretensioner / 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.
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.
