Abstract
The present invention provides a rear view mirror for a motor vehicle which is automatically adjustable to prevent the effects of dazzle e.g. by a vehicle approaching from behind at night. The mirror comprises an adjustable mirror surface (2) housed in a casing (3) and connected in an adjustable manner to an actuator (8) which engages an annular cam formation (26) having various cam profile heights whereby the mirror surface (2) can be adjusted by tilting. The cam formation (26) is part of a toothed wheel (11) driven by a small electric motor (21) the control circuit of which is actuated by a photosensor (38) so that mirror tilting is dependent on light intensity thresholds. The arrangement enables the various mirror adjustments to be achieved using uni-directional rotation of the motor and the toothed wheel (11) and this has the advantage of providing more reliable operation with less noise. The present adjusting mirror is also relatively inexpensive to manufacture.
