ABSTRACT:
A remotely adjustable rearview truck mirror includes a streamlined housing that is stationarily secured to the exterior of the truck cab, the housing having walls that define an enclosure that has a rearwarly facing rectangular aperture. A generally rectangular mirror support covers the aperture and is pivotally mounted for rotation about a vertical axis through one side of the aperture, and a sealing lid or flange extends generally forward from the periphery of the mirror support so as to lie in close overlapping relationship with the periphery of the aperture, and a sealing element extending along the aperture periphery, slidably engages the flange, and an electrically driven drive mechanism within the enclosure can be controlled from the cab to adjust the orientation of the mirror support. A wiper blade mechanism and a heater are mounted to the mirror support, and spray nozzles on the mirror support are supplied from a reservoir within the enclosure.
