ABSTRACT:
A seat belt webbing retractor (10) includes a belt webbing spool (50) and a length of belt webbing (16) wound on the belt webbing spool. A spring (82) biases the belt webbing spool (50) for rotation in a belt retraction direction. A pair of rotatable cable spools (90, 100) and a cable (110) transmit the biasing force of the spring (82) to the belt webbing spool (50) to apply a retraction force to the belt webbing (116). Each of the cable spools (90, 100) has a predetermined configuration to provide a desired retraction force curve (230).
