  • Patent number: 4981347
    Abstract: An electrically driving system for the outer rearview mirror erects or folds the mirror body by the operation switch for rotating the incorporated motor normally or reversively. The system comprises a momentary operation switch, normal and reverse relays and limit switches for disconnecting self-holding circuits of the relays and motors from a power source independently of one another by detecting erected and folded states of the mirror. When the normal or reverse relay is rendered operative by the momentary operation switch, the incorporated motors are driven to cause rotation of a plurality of the mirrors. The mirrors are stopped independently with disconnection of motor circuit caused by the action of the limit switches when they reach to the erected or folded state.

  • Patent number: 4973146
    Abstract: An electrically driving system for the rearview mirrors, wherein the incorporated motors are rotated normally or reversibly in response to the operation of a operational switch, thereby erecting or folding the mirror bodies. The system comprises a momentary operational switch, a relay circuit, a group of limit switches for cutting off the relay circuit and motor circuit respectively by detecting erected and folded positions of the mirror bodies, and a circuit for judging a folded state. When the operational switch is pushed, any folded mirror is detected within delay time of the circuit for judging a folded state. And only when both of the left and right mirror bodies are in the fold positions, the erecting relay is actuated to rotate the motors in the erecting direction.
