US Patent:

6488383, Dec 3, 2002

Filed:

Nov 30, 2001

Appl. No.:

10/015336

Inventors:

Karl H. Hanft - Holland MI
Edward A. Gahan - Fennville MI
David N. Sizemore - Cedar Springs MI

Assignee:

Hadley Products - Grandville MI

International Classification:

G02B 782

US Classification:

359871, 359872, 359855, 359864, 359865

Abstract:

A vehicular exterior rearview mirror assembly for large vehicles, such as trucks, includes a reflective element, a support bracket, and an actuator mounting the reflective element to the support bracket. A mirror housing is secured to the support bracket. The electrical actuator is mounted to the support bracket by a plurality of fasteners and includes an actuator housing, which has a peripheral surface extending around the fasteners. The support bracket provides bearing contact for at least a portion of the peripheral surface of the housing to reduce the vibration and improve the stability of the mirror assembly. The electrical actuator includes a movable member which supports the reflective element for movement therewith and which extends into the actuator housing and frictionally engages the housing to minimize vibration of the movable member when it pivots. The electrical actuator preferably includes a biasing member to enhance the friction between the movable member and the housing to further reduce the vibration of the movable member and, therefore, the reflective element supported thereon.
