Motor-powered adjustable rear view mirror
First Claim
1. A motor-powered adjustable rear view mirror for motor vehicles, comprising a housing (1, 1'"'"', 1") accommodating and supporting a mirror glass (3, 3'"'"') a fixing device (7, 7'"'"', 7") having means to be rigidly connected to a motor vehicle, a base plate connected in a stationary manner to the fixing means (7, 7'"'"' 7"), a universal joint (14, 14'"'"' 14") which is connected to the fixing device (7, 7'"'"' 7") and which bears the housing (1, 1'"'"', 1") pivotally about a central point (22) of the universal joint (14, 14'"'"', 14") and, at least one positioning drive (28, 29) connected in a stationary manner to the housing (1, 1'"'"', 1") and is coupled to the base plate (39, 39'"'"', 62) via a slider-crank transmission (34, 67, 75), by means of which the housing (1, 1'"'"', 1") is adjusted by pivoting about at least one pivot axis (47, 48) passing through said central point (22), wherein the slider-crank transmission (34, 67, 75) comprises a crank (35, 68, 76) coupled to the base plate (39, 39, 62) via a sliding bearing (42, 43, 74,83) and wherein there is articulated on the crank (35) by means of a crank joint (36) a push rod (37) which is displaceably guided in a bearing sleeve (41) which is connected to the base plate (39, 39'"'"') and wherein the slider-crank (35, 67, 75) is in itself pivotable about a longitudinal axis (44) of the sliding bearing (42, 43, 74, 83).

Abstract
A motor-powered adjustable rear view mirror for motor vehicles, particularly lorries, comprises a housing which supports and accommodates a mirror glass. Positioning drives are provided by means of which the housing can be pivoted and adjusted about two pivot axes which extend substantially at right angles to each other. In order to make the mirror of the simplest possible construction and so that it can be easily assembled and has a shallow but very stable design, each positioning drive is stationary in relation to the housing and is coupled via a slider-crank transmission to a base plate, the slider-crank transmission comprising a crank and a push rod connected thereto via a crank joint. The push rod is coupled to the base plate via a sliding bearing.
