Abstract
A seat belt retractor comprises a take-up shaft which is spring biased in a belt retracting direction; a planetary gearing having a sun gear nonrotatably mounted to the take-up shaft, a ring gear and a planet pinion; a mechanical tensionless mechanism which prevents the planet pinion from orbiting in the same direction as the belt retracting direction; and a motor actuated slack control mechanism meshing with the ring gear, wherein the tensionless state is established by preventing the orbiting movement of the planet pinion and the slack control is effected by rotating the ring gear.
