Where are back-wind seatbelt pre-tensioners located?

Explanation:
Back-wind seatbelt pretensioners are located in the lower part of the B-pillar on the rear seating area. This position keeps the pretensioner integrated with the belt retractor and anchor for the rear belt, allowing it to tighten the lap and shoulder belt quickly and effectively without altering the belt’s path or interfering with door or roof components. Placing a pretensioner in the front door or at the buckle would not provide the same reliable, belt-path–aligned action, and the roof area isn’t where rear belt pretensioners are typically mounted.
