A steering angle sensor including a case body having a through hole for a steering shaft. The case body is adapted to be fixed to a vehicle body. A cover is attached to an end portion of the case body and a printed board having a flat resistor element is provided at the end portion of the case body. A hollow rotor for passing the steering shaft therethrough is rotatably supported by the case body and the cover, and the hollow rotor has a positioning portion for positioning the steering shaft. A contactor is mounted on the rotor within the cover and disposed in sliding contact with the resistor element of the printed board. A spring is interposed between the steering shaft and the rotor to apply a resilient force thereto. The resistor element has a degree of variation of a sensor output voltage in a first range of steering angles, in straight running of a vehicle, larger than that in a range of steering angles exceeding the first range.

Steering angle sensor

A device for detecting rotation of a steeering wheel for motor vehicles is disclosed which comprises an encoding member rotatable together with a steering wheel and having markers at predetermined position, a sensor so disposed as to correspond to a locus of rotation of the markers; and a signal generating circuit for generating pulse signals representative of information on the rotation of the encoding member whenever the sensor is caused to correspond to the markers. A first casing housing and rotatably holding the encoding member and a second casing housing and holding the signal generating circuit are formed integrally with each other.

Device for detecting rotation of steering wheel for automobiles

An apparatus for controlling a seatbelt system in which the distal end portion of a webbing is moved in the longitudinal direction of a vehicle by a motor, thereby allowing the webbing to be automatically fastened to and unfastened from the body of an occupant. The apparatus has a motor overload detecting circuit which detects an overloaded state of the motor by detecting a change in the current flowing through the motor. When the motor is overloaded, the motor is turned OFF. Accordingly, even when the occupant moves during the movement of the webbing and the webbing consequently interferes with the occupant's neck or head, it is possible to prevent the occupant from feeling uncomfortable and the motor from being burned out.
