Abstract: A system for pretensioning a seatbelt includes a minispool and a drive rod. The drive rod includes a spiral portion that, when driven along a longitudinal axis, causes the minispool to rotate about the longitudinal axis. The spiral portion of the drive rod engages the minispool, which includes corresponding structure that tracks the spiral portion. The minispool is restricted from longitudinal travel such that tracking the spiral portion causes the minispool to rotate and the drive rod passes through the minispool. In another form, the minispool can be arranged transverse to the longitudinal axis, with the translation of the drive rod causing the minispool to translate in the same direction of the drive rod. The minispool can include teeth that engage a bracket, such that the translation of the minispool causes the minispool to rotate as it translates.
