摘要： A seat belt retractor having a function of taking up a seat belt using a motor. A spool is fitted in a base frame such that a torsion bar functions as a shaft of the spool. Two gear-clutch casings are disposed on the left and right sides of the spool via a pretensioner and a locking mechanism, respectively, wherein two motors are disposed to the gear-clutch casings, respectively. The two motors achieve respective functions which are different from each other and rotate at respective constant speeds.

摘要： In a seat belt control device of the invention, when a buckle switch detects disengagement of a buckle and a tongue plate of a seat belt, the seat belt is retracted through a motor. In addition, the seat belt is re-retracted, through a motor, when a passenger detector detects that no passenger is present in an automobile, when a door switch detects that a door opens, or when an engine key switch detects that an engine key is pulled out or is in an off state. Thus, the seat belt can be positively retracted. Therefore, when a passenger gets off or is going to get off, the seat belt can be securely retracted to thereby prevent the seat belt from being caught by a projection in a compartment or by the door of the automobile.
摘要翻译：在本发明的安全带控制装置中，当扣环开关检测到带扣和安全带的舌板脱离时，安全带通过马达收回。此外，当车门开关检测到门打开时，或当发动机钥匙开关检测到发动机钥匙时，当乘客检测器检测到没有乘客存在于汽车中时，安全带通过马达被重新缩回被拉出或处于关闭状态。因此，安全带可以被正确缩回。因此，当乘客下车或下车时，安全带可以可靠地缩回，从而防止安全带被车厢内的突起或汽车的门卡住。

摘要： A seat belt retractor is formed of a reel for winding a seat belt, and a spring member connected to the reel for providing a retracting force thereto. The retracting force is weak not to provide a feeling of oppression to a passenger when the passenger has fastened the seat belt. A motor is connected to the reel for driving the reel only in a direction of retracting the seat belt to generate a retracting force greater than that of the spring member. Thus, the seat belt retractor retracts the seat belt by sufficiently great retracting force, but does not provide a feeling of oppression to the person when properly fastened.

摘要： A drive circuit for an ultrasonic motor includes a DC power source, a transformer for applying to the ultrasonic motor two phase high frequency voltage alternating currents having a predetermined phase difference for driving the ultrasonic motor, a switching device interposed between the DC power source and the transformer for allowing a direct current from the direct DC power source to flow to the transformer at a predetermined timing, and a CPU connected to the switching device for controlling the switching device at the predetermined timing. Thus, the alternating current having an optimum frequency can be reliably and easily obtained. The drive circuit may include a vibration attenuating device operated when the ultrasonic motor is stopped. As a result, vibration of a stator of the ultrasonic motor is gradually reduced.

摘要： A seat belt retractor for retracting a seat belt is formed of a first motor for retracting a seat belt with a force not providing a pressing feeling to a passenger, a second motor having a torque greater than that of the first motor for retracting the seat belt with a force forcibly holding the passenger to a seat, and a control circuit connected to the first and second motors for controlling the same. Thus, the seat belt retractor can perform a forced retraction and a normal retraction with an economical structure.

摘要： In controlling a seat belt retractor, at least one of signals selected from a state signal showing a movement of an occupant wearing a seat belt and an external signal obtained from detecting means installed in a vehicle during running thereof is received. Then, a rotational torque of a motor is selected to a predetermined reduction ratio corresponding to at least one of the state signal and the external signal from a plurality of torques. The motor is controlled to a predetermined torque, to thereby wind the webbing on the spool.
