ABSTRACT:
A passive vehicle seat belt system includes measures to prevent overheating of the drive motor and obstruction of system operation. Drive motor excess current demand is sensed to effect motor de-energization and/or disabling of latching means of a retractor included in the system and/or operation of an indicator light. The indicator light can prompt manual motor de-energization. Disabling of retractor latching means can be effected by a belt movement command signal. Retractors with means for signalling operation of latching means, with solenoid means for disabling latching means, and with means for indicating when a predetermined belt length has been received therein, are described.
