ABSTRACT:
A vehicle seat belt retractor (10) includes a spindle (22), a ratchet wheel (30) and a locking pawl (44). The locking pawl (44) is movable between a disengaged position and an engaged position in which it blocks rotation of the ratchet wheel (30) and the spindle (22) in an unwinding direction. The locking pawl (44) is moved into its engaged position in response to a predetermined amount of rotation of the spindle (22) in the unwinding direction. The locking pawl (44) moves back to its disengaged position in response to rotation of the spindle (22) in an unwinding direction. The retractor (10) further includes a torsion spring (210) and a leaf spring (250) acting in series between the spindle (22) and the locking pawl (44).
