Abstract
A vehicle occupant restraint system that includes a clutch mechanism, an electric actuator, a spindle and a power transmission mechanism that transmits motive power from the actuator to the clutch mechanism. The transmission mechanism has a low reduction transmission path that reduces rotation of the actuator at a low reduction ratio, a high reduction transmission path that reduces rotation of the electric actuator at a high reduction ratio, and switching means. When a possible collision is detected, the actuator is positively rotated and rotation is transmitted to the clutch mechanism at a high speed and low torque via the low reduction transmission path, until coupling of the clutch mechanism is complete. Subsequently, the transmission mechanism is switched to the high reduction transmission path and rotation is transmitted to the clutch mechanism, at a low speed and high torque, to wind the seatbelt around the spindle.
