  • Power driven wiper system for outside vehicle mirrors
    Patent number: 6453504
    Abstract: An exterior rear view mirror is wiped by a flexible blade supported by a pivotal arm mounted on a carriage supported for linear movement on a track mounted on a housing attached to the mirror. A shuttle is supported within the housing for reciprocating vertical movement by a motor driven reversing lead screw, and a magnetic coupling connects the shuttle to the carriage with the housing extending therebetween. A cam and follower lift and reset the arm and blade relative to the mirror in response to movement of the carriage at the top of the mirror, and the track and housing are each formed from a non-magnetic material so that the shuttle moves the carriage by a magnetic field.
