Abstract
A seat belt retractor spool has a spool body with opposed end flanges. A ratchet wheel is arranged on one end flange. A torsion bar is located in a bore in the spool body and is coupled to the ratchet wheel by means of a toothed portion at one end thereof. The other end of the torsion bar has a plurality of radial projections which cooperate with axial protrusions on the end flange to couple the bar 10 to the spool.
