ABSTRACT:
There is provided a passive seatbelt system which is actuated by an electric motor. The seatbelt system comprises command switch means for generating seatbelt activation and deactivation signals, switch means for detecting the position of a seatbelt, and a control circuit for controlling the motor. The control circuit further comprises a driving circuit for driving the motor and a computing circuit for controlling the driving circuit in accordance with the output signals of the two switch means. The driving and computing circuits included in the control circuit are constructed using hybrid integrated circuits (IC) and the thus miniaturized control circuit can be made integral with the electric motor.
