Abstract

See full text

An actuator device for a rearview device of a motor vehicle includes at least one retaining element, at least one adjusting element, at least one driving means, and at least one heat-conducting means. The adjusting element is configured to be transferred into a plurality of functional positions, in particular from a basic position into at least one end position. The driving means includes at least one shape-memory element in the form of a wire, extending between the retaining element and the adjusting element and configured to be secured to both. Extension of the shape-memory element can be modified when electrically energized. The adjusting element can be transferred from one functional position into another functional position by modifying the extension. The heat-conducting means lies in contact with the driving means at least in the end position of the adjusting element. At least one switching means provides no contact between the driving means and the heat-conducting means in the basic position of the adjusting element and causes contact between the driving means and the heat-conducting means.
