An electric motor circuit for controlling an electric motor of a mirror adjustment mechanism includes a switch-off circuit that is provided with a current sensor for measuring the electrical supply current and, depending thereon, generating a voltage. In an embodiment, a current branch is configured to be rendered conductive in response to the generated voltage; an electronic switch is configured to interrupt the supply current as a result of the current branch being rendered conductive. The current branch may be configured to form a first branch of a current mirror which is out of balance and is dimensioned such that the first branch does not carry current under normal operating conditions of the motor, and a second branch is conductive. In an embodiment, upon the occurrence of a supply current that is greater than a predetermined critical level, the first branch is also rendered conductive.

Mirror adjustment mechanism, wing mirror unit and method

An electric motor circuit utilized, for instance, for adjusting a wing mirror of a vehicle is provided with a motor with a driving circuit. The driving circuit includes a relay switch element included in series with the motor and a protecting circuit for bringing the relay switch element into a non-conductive position at overload of the motor. The protective circuit is provided with an exciting coil and a deenergizing coil. The exciting coil serves for bringing the relay switch element into a conductive position. The exciting coil is included parallel to the motor in series with the relay switch element. The deenergizing coil is included in series with the motor for bringing the relay switch element in a non-conductive position when a current through the deenergizing coil and the motor exceeds a threshold value. Motor and motor protection are preferably included together in the housing of a mirror construction.
