First Claim
Patent Images
1. A seatbelt retractor comprising:
- a spool for winding a seatbelt, a motor for generating rotational torque to rotate the spool, a power transmission path situated between spool and the motor, a clutch mechanism attached to the power transmission path for allowing the power transmission path to transmit the rotational torque of the motor to the spool in a connected mode, and for prohibiting the power transmission path to transmit the rotational torque to the spool in a disconnected mode, clutch mechanism disconnection detecting means for detecting disconnection of the clutch mechanism, and a motor control device connected to the motor for stopping the motor according to a clutch disconnection signal from the clutch mechanism disconnection detecting means.

Abstract
A seatbelt retractor includes a spool for winding a seatbelt, a motor for generating rotational torque to rotate the spool, a clutch mechanism for connecting a power transmission path to transmit rotational torque of the motor to the spool in a connected mode and for disconnecting the power transmission path in a disconnected mode, and a clutch mechanism disconnection detecting device for detecting disconnection of the clutch mechanism. A motor control device stops the motor according to a detection signal from the clutch mechanism disconnection detecting device.
