Abstract:
An assembly having a retractor and a pretensioner whereby the pretensioner can be employed to provide load limitation features. The pretensioner may also be used without the load limitation features. The pretensioner has a drive mechanism including a plurality of pretensioner balls sized to engage a pinion, the pinion operatively connected to the seat belt through a force limiting element. The pretensioner defines a guide surface structured to guide the pretensioner balls along a ball path along the pinion. The guide surface includes features to engage a pretensioner ball and block the pinion.
