Seat belt retracting device
First Claim
1. A seat belt retracting device having a body containing a motor for retracting or retracting and unwinding the seat belt, comprisinga one-chip integrated circuit (IC) for controlling operation of the motor, wherein the one chip IC is mounted on the body of the seat belt retracting device and includes a control output power circuit, a motor control power circuit, a communication control power circuit;
- and wiring connecting the one-chip IC, the motor, and a switch for controlling the motor, and wherein a portion of the wiring is integrally formed within the body of the seat belt retracting device.

Abstract
A seat belt retracting device having a motor for retracting a seat belt having a tongue adapted to engage a buckle. The device includes an electrical circuit for controlling operation of the motor with a one-chip integrated circuit (IC). The circuit includes a control output power circuit; a motor control power circuit; and a communication control power circuit. The motor is configured to operate for a first prescribed period of time to retract the seatbelt from the moment at which disengagement between the buckle and the tongue is detected.

6. A seat belt retracting device having a motor for retracting a seat belt having a tongue adapted to engage a buckle, comprising an electrical circuit for controlling operation of the motor with a one-chip integrated circuit (IC) comprising:
-
a control output power circuit;
a motor control power circuit; and
a communication control power circuit;
wherein the motor is configured to stop operating when the unwinding of the seat belt is detected while the motor is operating to retract the seat belt; and
wherein the motor is configured to restart and operate for a first prescribed period of time after the seat belt is unwound for a second prescribed period of time; and
wherein retraction of the seat belt by the motor is not carried out while engagement between the buckle and the tongue is detected.
