Abstract: A seatbelt pretensioning retractor assembly for use in a passenger vehicle is provided. The pretensioning assembly includes a one-piece tread head pinion including a ring portion having a plurality of teeth and a pair of flanges on each side of the teeth. The tread head pinion is formed as a single piece and includes a shaft extending from a side and a bearing portion extending from a second side. A bending element mounting portion extends from the bearing portion. The one-piece tread head pinion is attached to a spindle via a torsion bar, and the spindle bears against the bearing portion when the spindle rotates relative to the tread head pinion. The one-piece tread head pinion may include a staking cavity extending into the bearing portion with a staking wall that is deformable toward a digressive bending element inserted into the staking cavity.
