Abstract
A vehicle mirror assembly comprises a housing assembly and a mirror unit mounted on the housing assembly. A support assembly is provided which is constructed and arranged to be fixedly mounted on a vehicle and to support the housing assembly thereon in an operative position extending laterally outwardly from the vehicle so that the mirror unit serves as an exterior rear view mirror for the driver of the vehicle. A power operated pivot assembly is provided between the support assembly and the housing assembly constructed and arranged to enable the housing assembly to be pivoted with respect to the support assembly about a generally upright axis (1) between the operative position thereof and a folded position with respect to the vehicle in response to the power operation of the pivot assembly and (2) from the operative position thereof in either direction in response to an unwanted impact blow applied in either direction thereto. The power operated pivot assembly includes at least one tubular member carried by one of the assemblies in concentric relation to the upright axis and an electric motor constructed and arranged within the tubular member to be operated by electrical power in a manner to generate flux for which the tubular member constitutes a flux yoke.
