ABSTRACT:
TECHNICAL FIELD AND BACKGROUND OF THE INVENTION
The present invention generally relates to an interior rearview mirror assembly and, more particularly, to an interior rearview mirror assembly for a vehicle memory mirror system.
Conventional vehicle memory mirror systems typically include one or more exterior mirror assemblies which are equipped with electrically operated motors that provide for repositioning of the mirror assemblies' reflective elements with respect to one or more axes. Particularly for exterior sideview mirrors, it is known to incorporate memory-positioning systems so that a driver of a vehicle may select a desired position of the exterior sideview mirror by simply pushing a button. Less known, but currently available, are memory mirror systems, which include memory positions not only for the exterior sideview mirror assemblies but further, for the interior rearview mirror assembly. Incorporated into each of these mirror assemblies is a drive mechanism, which provides for the memory positions for each of the reflective elements in the mirror assemblies.
Referring to
FIG. 6
, a conventional interior mirror assembly for a memory mirror system includes a housing with a pivotal portion, such as a casing C, and a fixed portion, such as a mounting arm M, which mounts the casing to a windshield W on, for example a mounting button, as is known in the art. A reflective element assembly R is supported in the pivotal portion or casing by an electrical actuator A. Heretofore, the actuator or drive mechanisms that have been incorporated into these interior rearview mirror assemblies necessarily add weight to the pivotal portion and, further, result in crowding out of other accessories or features which may be incorporated into the interior rearview mirror casing. While such memory mirror systems (which include both exterior and rearview mirror assemblies) are known, they are not widely used. It has been found that the weight of the motor, especially in interior mirror assemblies, has impacted the vibration performance of the mirror assembly. In addition, as the interior rearview mirror assembly has been more recently targeted as a location for storing or holding a multitude of electronic and electrical devices and accessories the space in the interior mirror assembly casing has become more coveted.
For example, interior mirror assemblies now incorporate map lights, displays, videos, and other utility functions, such as described in copending U.S. patent application entitled REARVIEW MIRROR ASSEMBLY WITH UTILITY FUNCTIONS, Ser. No. 09/449,121, filed Nov. 24, 1999, the disclosure of which is herein incorporated by reference in its entirety. Other examples of the various electronic and electrical features now incorporated into interior rearview mirror assemblies include: Video screens, such as disclosed in copending U.S. patent application entitled INTERIOR REARVIEW MIRROR ASSEMBLY INCORPORATING A VIDEO SCREEN, filed Mar. 1, 2000, Ser. No. 60/186,520; microphones and/or speakers, such as disclosed in U.S. patent applications Ser.
