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.

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.
摘要翻译：一种用于安全带约束系统的安全带卷收器。牵开器包含双重旋转陀螺仪单元和自适应负载限制特性。优选地，旋转拉伸器位于卷收器卷轴的相对端上，用于驱动卷轴以预张紧旋转。可以单独激活第一预紧器以提供预张紧旋转。在本发明的一个实施例中，如果第二预紧器没有被激活，系统将被接合以提供给定的带负载限制特性。在第一预张紧器被点火之后，可以发射第二个陀螺仪，以增加收费能力或激活牵开器的不同负载限制特性。
