ABSTRACT:
An apparatus, which exposes the blind spot in the direction in which a vehicle makes a turn, to be installed at the back of mechanically or electrically operated side-rear view mirrors. A mechanical device, connected to a mirror unit and to the frame, having a diaphragm sealingly disposed therein. When a winker switch is activated, the diaphragm housing is activated by vacuum, causing the diaphragm to be sucked backwards, resulting in said mirror unit pivoting backwards to expose the blind spot, further, when there is no vacuum the mirror unit is returned to its original position by the returning means. The invention also operates where instead of one mirror, there are two mirrors hinged together, whereby the mechanical device pivots only one of the mirrors to expose the blind spot, such that the other mirror is left to expose the rear-view of the car. The invention can also operate by pivoting the mirror frame to expose the blind spot rather than pivoting the mirror unit.
