A pyrotechnic pretensioner is integrated into some seatbelt retractor. The pretensioners are used to tighten the seatbelts during a collision to make sure the occupants are securely held in their seats.
When operated by the Restraints Control Module (RCM), the pretensioners rotate the spool holding the end of the webbing to tighten the seatbelt.
On North American Specification (NAS) market vehicles, a pyrotechnic load limiter actuator is incorporated into the retractor of both driver and passenger seatbelts. This serves as an adaptive load limiter. The adaptive load limiter has 2 different load limits, the standard load limit and a lower load limit. The lower load limit is designed to reduce the chest loading for smaller seat occupants during an impact. It is engaged when the Restraints Control Module (RCM) fires the load limiter actuator.
