ABSTRACT:
A vehicle seat belt retractor (10) has a spool (20) on which seat belt webbing (26) is wound. An externally-toothed ratchet wheel (50) is rotatable with the spool (20) in a belt withdrawal direction (22). A first pawl (70) is supported on a housing (12) for pivotal movement about a first axis (72) into engagement with the ratchet wheel (50) to block rotation of the ratchet wheel (50) in the belt withdrawal direction (22). An inertia member (62) supported on the housing (12) is movable in response to vehicle deceleration greater than a predetermined deceleration to pivot the first pawl (70) into engagement with the ratchet wheel (50) and thereby block rotation of the ratchet wheel (50) and the spool (20) in the belt withdrawal direction (22). A second pawl (90) is supported on the housing (12) for pivotal movement relative to the ratchet wheel (50) about a second axis (92) spaced from the first axis (72). The first pawl (70) has a portion for supporting the second pawl (90) and for effecting movement of the second pawl (90) about the second axis (92), upon movement of the first pawl (70) about the first axis (72), into a ready position. The second pawl (90), when in the ready position, is engageable with the ratchet wheel (50) to block rotation of the ratchet wheel (50) and thus of the spool (20) in the belt withdrawal direction (22).
