ABSTRACT:
A retractor (24) for seat belt webbing (22) includes a first spool (60) for a first wound length of seat belt webbing (30) and a second spool (62) for a second wound length of seat belt webbing (32). The first and second spools (60, 62) are supported for winding and unwinding rotation. The retractor (24) further includes a cinch mechanism (110). The cinch mechanism (110) blocks unwinding rotation of the first spool (60) in response to a first amount of rotation of the spools (60, 62) which includes a predetermined amount of unwinding rotation of the second spool (62). The cinch mechanism (110) blocks unwinding rotation of the second spool (62) in response to a second amount of rotation of the spools (60, 62) which includes a predetermined amount of unwinding rotation of the first spool (60).
