    Abstract: A vehicle sensitive retractor control system having reduced sensitivity to Z-axis acceleration experienced during normal driving. The retractor control system incorporates a rolling mass and a locking lever which, in a resting position, are arranged such that the locking lever does not engage a ratchet wheel of a seat belt retractor spool. In response to accelerations in the horizontal plane, the rolling ball mass becomes unseated from its resting position and allows the locking lever to rotate due to the position of its center of gravity relative to its pivot point allowing it to pivot and lock the retractor. In response to Z-axis acceleration, the rolling mass is prevented from contacting the locking lever by a mass restrictor.

    Abstract: A seat belt retractor for use with a seat belt webbing includes a spindle, a tread head part, a torsion bar, a stop nut and an energy management element. The spindle is configured for winding the seat belt webbing around the spindle. The tread head part is configured for having a locked condition or a free condition. The torsion bar is engaged with the spindle and the tread head part and configured to deflect torsionally by allowing relative rotation between the spindle and the tread head part when the tread head part is in the locked condition. The stop nut is operatively coupled with the tread head part and the spindle and configured to move in axial direction. Furthermore, the energy management element placed between the stop nut and the tread head part is configured to be deformed by the axial movement of the stop nut.

    Abstract: A seatbelt pretensioner system for use in a seatbelt retractor assembly having a spindle and a frame includes a housing adapted for being mounted to the frame and having an interior cavity, a pretensioner tube having a first tube end in fluid communication with a gas generator and a second tube end in fluid communication with the interior cavity of the housing, a pinion being rotatably mounted in the housing and fixedly coupled to the spindle adapted for taking up seatbelt webbing during pretensioning, and a pretensioner rod disposed inside the pretensioner tube. Further, the pretensioner rod has a proximal end disposed towards the gas generator and a distal end disposed away from the gas generator. In addition, the housing is formed with at least two levels including an inboard portion and an outboard portion to store the pretensioner rod after pretensioning.
