An in-line seat belt pretensioner is provided that includes a frame containing a first guide member and a second guide member for tensioning of seat belt webbing upon pretensioner activation. As the pretensioner is activated, the seat belt is tensioned by activation of an actuator operably coupled to the second guide. The second guide is then routed over a vertically stationary first guide that is slidably engaged within a slot within the frame, thereby contributing to reducing the load on the occupant. A low-friction material employed in the manufacture of the guide member(s), contributes to a smoother and less abrupt tensioning of the seat belt upon activation of the pretensioner.
