Abstract:
A multi-function control apparatus for a motor vehicle, said apparatus comprising:a motor having an output shaft, a gear operably associated with said output shaft so as to be driven by said output shaft, said gear having a hub with a first diameter, a drive shaft having an axis of rotation and being disposed concentrically within said hub of said gear and having a second diameter sufficiently smaller than said first diameter to provide a clearance between said drive shaft and an inside surface of said hub; a wiper device operably driven by rotation of said drive shaft; an elastomeric bushing disposed over said drive shaft within said hub, said elastomeric bushing operating to couple said gear and said drive shaft such that said elastic member transmits a driving force from said gear to said drive shaft to drive said drive shaft rotationally and said elastic member enabling a degree of rotation of said gear relative to said drive shaft in at least one rotational direction if said drive shaft becomes immoveable; and a second device operably driven by movement of said output shaft, said wiper device being substantially stationary when said second device is operably driven, wherein said elastic member further allows movement of said second device if said wiper device is immoveable.
