POWER DRIVEN WIPER SYSTEM FOR OUTSIDE VEHICLE MIRRORS

摘要

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 minor. A shuttle is supported within th e 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 an d 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.
