Seat Belt Pretensioner (BPT)

Description and Operation

Description

The seat belt pretensioners (BPT) are installed inside the center pillars (left and right). In a frontal collision of a certain severity, the seat belt pretensioner helps reduce the severity of injuries to front 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.
