Abstract

An electrically and manually operable mirror for a vehicle including a base, a housing rotatably coupled to the base, a transmission gear rotatably coupled to the base and provided between the base and the mirror, a first clutch provided between the transmission gear and the housing, a second clutch provided between the transmission gear and the base and a motor for driving the transmission gear when electric power is applied to the motor.

Claims

1. An electrically and manually operable exterior storage type mirror for a vehicle comprising:

a base for mounting said storage type mirror to a body of said vehicle;

a mirror housing rotatably coupled to said base;

a transmission gear rotatably coupled to said base and provided between said base and said mirror housing;

a first clutch means provided between one surface of said transmission gear and said mirror housing, said first clutch means comprising convex parts on said one surface of said transmission gear, concave parts on said mirror housing engaging with said convex parts and spring means for causing said convex and concave parts to be in resilient engagement;

a second clutch means provided between another surface of said transmission gear and said base, said second clutch means having an engaging force greater than an engaging force of said first clutch, said second clutch means comprising convex parts on said another surface of said transmission gear, concave parts on said base engaging with said convex parts and spring means for causing said convex and concave parts to be in resilient engagement; and

a means fixed to said mirror housing and provided within said mirror housing for rotating said transmission gear when electric power is applied to said means; and

wherein the height of said convex parts of said first clutch is less than a height of said convex members of said second clutch.

2. A mirror according to claim 1, wherein said convex parts of said first and second clutch means are trapezoidal in shape.

3. A mirror according to claim 2, wherein said means for sensing the rotational position comprises a limit switch.

4. A mirror according to claim 1, wherein said means for rotating said transmission gear comprises an electric motor and a gear train provided between an output of said motor and said transmission gear.

5. A mirror according to claim 1, further comprising a means for sensing the rotational position of said mirror housing relative to said base.

6. An electrically and manually operable exterior storage type mirror for a vehicle comprising:

a base adapted to be anchored to a body of said vehicle;

a mirror housing rotatably coupled to said base;

a transmission gear rotatably coupled to said base and provided between said base and said mirror housing;

a means mounted within said mirror housing for rotating said transmission gear when electric power is applied to said means;

a first clutch means provided between one surface of said transmission gear and said mirror housing, said first clutch means comprising convex parts on said one surface and concave parts on said mirror housing engaging with said convex parts;

a second clutch means provided between another surface of said transmission gear and said base, said second clutch means having an engaging force greater than that of said first clutch means, said second clutch means including convex parts on said another surface and concave parts on said base engaging with said convex parts the height of said convex parts of said first clutch means being less than that of said convex parts of said second clutch means; and

a spring means causing said convex and concave parts of said first and second clutch means to be in resilient engagement.
