An apparatus (40) for pretensioning seat belt webbing (16) which is extensible about an occupant of a vehicle seat (14) has at least two different output levels. Sensors (110, 120, 130) sense at least one characteristic of the occupant of the vehicle seat (14). A controller (100) is operatively connected to the sensors (110, 120, 130) for controlling the output level of the pretensioning apparatus (40) based on the characteristics of the occupant sensed by the sensors. The at least two output levels of the pretensioning apparatus (40) correspond to respective levels of force applied to the seat belt webbing (16) which in turn correspond to respective levels of force imposed on the vehicle occupant by the seat belt webbing.
