Abstract: A seatbelt pretensioner system for use in a seatbelt retractor assembly having a spindle includes a frame assembly having a frame and an attachment bracket adapted to be interlocked to have an inner space for receiving the spindle, 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.

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.
