    摘要: A seat belt retractor for use in seat belt restraint systems. The retractor incorporates dual rotopretensioner units and adaptive load limiting characteristics. Preferably, the rotopretensioners are positioned on opposite ends of a retractor spool for driving the spool for pretensioning rotation. A first pretensioner may be activated alone to provide pretensioning rotation. In one embodiment of the invention, if the second pretensioner is not activated, the system will be engaged to provide a given belt load limiting characteristic. A second rotopretensioner may be fired either after the first pretensioner is fired to increase pay-in capacity or to activate a different load limiting characteristic for the retractor.

    摘要: 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.
