摘要： A vehicle seat belt retractor (10) includes a frame (12) supporting a spool (50) on which seat belt webbing (72) is wound for rotation in belt withdrawal (76) and belt retraction (75) directions. A lever (196) for use in preventing rotation of the spool (50) in the belt withdrawal direction (76) has a cylindrical portion (220) and a key (224) extending radially outward from the cylindrical portion (220). The lever (196) is supported for pivotal movement on a support member (112) that has a cylindrical chamber (222) for receiving the cylindrical portion (220) of the lever (196). A keyway (226) extends radially outward from the cylindrical chamber (222) for receiving the key (224) of the lever (196). The keyway (226) includes a surface (227) engageable by the key (224) of the lever (196) to prevent axial movement of the cylindrical portion (220) out of the cylindrical chamber (222).

摘要： A seat belt retractor (10) for mounting on a vehicle seat back (22) includes a spool (110) on which seat belt webbing (32) is wound. The retractor (10) includes inertia sensing means (40) for blocking rotation of the spool (110) in a belt withdrawal direction (124) in response to vehicle deceleration above a predetermined deceleration. The inertia sensing means (40) comprises a first inertia member (222) movable from an unactuated position to an actuated position in response to vehicle deceleration above a predetermined deceleration, and sensor means (230) operable to block rotation of the spool (110) in the belt withdrawal direction (124) in response to movement of the first inertia member (222) from the unactuated position to the actuated position. The sensor means (230) is operable to block rotation of the spool (110) in the belt withdrawal direction (124) in response to tilting of the vehicle seat back (22) by an amount more than a predetermined amount when the first inertia member (222) is in the unactuated position.
