Car door mirror equipped with bearing magnetometer
First Claim
1. In a vehicle having a vehicle body defining a driver location and at least one rear view door mirror assembly located outside of said vehicle body and linked to said vehicle body within view of a vehicle driver located at said driver location, the improvement comprising the combination of a direction-indicating magnetic compass on said rear view mirror, said compass defining a magnetic body influenced by the magnetic field of the earth for indicating a compass direction and located within a frame for said mirror but external to said mirror within said frame and at a distance from said vehicle body to reduce the influence of magnetic effects from metal in the body of said vehicle, and a bearing mark located on said compass for indicating at least one compass direction and arranged to be visible to a driver located at said driver location so that the driver is enabled to accurately view directly the direction of travel of said vehicle when viewing said rear view door mirror from the angle of inclination of said driver to said mirror.

Abstract
A compass attached to a car door mirror is disclosed which provides protection for the compass and improved readability, while avoiding the reliability problems of compasses mounted inside the car. The compass is embedded in the frame of the car door mirror which makes it both less obtrusive and physically more secure.

6. In combination, a rear view door mirror assembly, structurally adapted to be linked exteriorly to a door of a vehicle having a vehicle body defining a driver location, and located at a position remote from the body of said vehicle at a location proscribing a view for a driver of said vehicle located at said driver location at a first angle of inclination;
- and
a freely-rotatable compass defining a magnetic body influenced by the magnetic field of the earth for indicating a compass direction of travel of said vehicle, said compass being located in a frame for said rear view door mirror at a distance from said vehicle body to reduce the influence of magnetic effects from metal in the body of said vehicle, said compass further including a bearing mark indicating at least one compass direction arranged to be visible to the driver located at said driver location within said vehicle so that the driver is able to accurately view directly the direction of travel of said vehicle when viewing said rear view door mirror. - View Dependent Claims (7, 8)
