1. A vibration-stabilized rearview mirror assembly for vehicles comprising:

  • a mirror housing having an inside surface defining an interior space;

    a reflective mirror element having a perimeter edge and adjustably mounted for pivotal movement about a center of rotation within said housing interior space, said center of rotation having a pair of axes of rotation which are perpendicular to one another and pass therethrough;

    a first vibration stabilizer mounted for sliding movement on said mirror element along one of said axes of rotation, extending beyond said perimeter edge of said mirror element, and engaging a first portion of said inside surface of said housing;

    a second vibration stabilizer mounted for sliding movement on said mirror element along the other of said axes of rotation and extending beyond said perimeter edge at a position spaced from said first stabilizer, said second stabilizer extending perpendicular to said first stabilizer and engaging a second portion of said inside housing surface;

    a spring engaging and biasing said stabilizers outwardly of said mirror element perimeter edge such that said stabilizers continuously engage said inside housing surface to reduce vibration of said mirror element while extending and retracting against said spring to adjust for varying distances between said perimeter edge of said mirror element and said inside housing surface when the position of said mirror element within said housing is adjusted;

    said spring simultaneously engaging both said first and said second stabilizers, simultaneously biasing both said stabilizers into engagement with their respective inside housing surface portions, and being positioned to provide substantially equal force and loading on said first and second stabilizers.
