Abstract:
An outside rearview mirror assembly for a motor vehicle including a housing adapted to be attached to the motor vehicle and including an annular rim circumscribing a cavity defined by the housing, and a mirror glass assembly positioned in the cavity within the housing rim and mounted for selective movement relative to the housing to selectively vary the position of the mirror glass assembly relative to the housing and thereby selectively vary the image perceived in the mirror glass assembly by a motor vehicle operator, characterized in that:the mirror assembly further includes a damper device positioned within the cavity between the housing and the mirror glass assembly and operative to damp vibrational movement of the mirror glass assembly relative to the housing whereby to present a steady mirror image to the operator; and the damper device comprises a first member, a second member defining a slide structure mounted for reciprocal sliding movement in the first member and thereby defining a chamber therebetween, and a viscous material trapped in and filling the chamber and dampening the reciprocal sliding movement of the slide structure in the first member, wherein said chamber is sealed, and one of said members is connected to said mirror glass assembly and the other of said members is connected to said housing to damp vibrational movement of the mirror glass assembly relative to the housing.
