Abstract
Abstract A rear view mirror for vehicles which is adjustable in two planes and wherein a mirror support which supports the mirror glass is arranged inside a mirror housing and coupled through a cruciform joint with the housing which accommodates the adjusting drive. Adjustment of the mirror support relative to the mirror housing is obtained by application of the adjusting drive to the axes of the cruciform joint. The mirror assembly provides an absolutely sealed drive housing and is virtually unrestrictedly adjustable about the vertical axes, with minimized constructional depth, as both axes of the cruciform joint are connected with the drive housing, they are directly driven by the adjusting drive and are relatively independently rotatable, one axis being attached to the mirror support and the other axis to the mirror housing.
