Seat Belt Pretensioner (BPT)

Description and Operation

Description

Seat belt pretensioners (BPT) are installed inside the center pillars (LH & RH). When the vehicle is subjected to a certain degree of frontal impact, the seat belt pretensioners help reduce the severity of injuries to front seat occupants by retracting the seat belt webbing.

This prevents front occupants from moving forward and striking the steering wheel or instrument panel in a vehicle collision.
