Problems solved by technology

However, while this contact on one side of the tab cancels out most of the vibrational frequencies, it contributes to some harmonics, which become defective damping
In addition, the materials commonly used to make moving plates do not guarantee elasticity and become unstable over time especially at moderate or high temperatures
For this reason, after a certain time of exposure of the tabette to climatic factors, the result may be insufficient damping, or even zero damping

Embodiment Construction

[0014] Reference is made to Figure 1, which shows a frame 21 including vibration damping means for an exterior rearview mirror assembly of a motor vehicle according to the closest state of the art. The aforementioned frame 21 is adapted to support a mobile plate 23 to which at least one mirror 29 is fixed. The above-mentioned mobile plates 23 are assembled by means of joints of the joint type that allow joint rotation of the mobile plates 23 on two coordinate axes. A box is generally mounted on the frame 21, the box housing the adjustment mechanism including movement transmission means connected to the moving plate 23 for changing its position. The box houses said adjustment mechanism, said knuckle-type joint being conventional and schematically shown as a whole by dashed line 22 in FIG. 1 .

[0015] In order to attenuate possible vibrations transmitted from the frame 21 to the mobile plate 23 , the mobile plate 23 comprises tabs 24 protruding outwards from the lower part of ...

Abstract

The present invention relates to a frame comprising a vibration-damping device, which is intended for the outside rear-view mirror assembly of a motor vehicle. According to the invention, a moving plate (3) bearing a mirror (9) is connected to the inventive frame (1) by means of a knuckle-type joint. Optionally, a case (2) is installed on the frame (1) in order to house a position-adjustment mechanism which is connected to the moving plate (3) and which is actuated in order to vary the position of said plate (3) in relation to two co-ordinate axes. According to the invention, a tab (4), which projects out from part of the moving plate (3) opposite the frame (1), is pressed such that it can slide through a damping arrangement (5) comprising a pair of elastic arms (6) which form part of the frame (1) and which extend therefrom. The aforementioned elastic arms (6) are arranged in the form of a clamp in order to form a pressure contact against the opposing faces of the tab (4).

Description

technical field [0001] The present invention relates to a frame for an exterior rearview mirror assembly of a motor vehicle comprising damping means, and more particularly to a frame obtainable by injection molding integral with the damping means forming the part of the shock absorber. Background technique [0002] Exterior rear view mirrors for motor vehicles are well known and comprise a frame fixed to the vehicle and a moving plate to which the mirror is fixed. The moving plate is connected to said frame by a kinematic joint type joint having degrees of freedom of rotation about two mutually perpendicular axes generally parallel to the reflective surface of the mirror. The two axes intersect each other at a point forming the center of the two rotations, so that this point cannot move, so the joint point for joining the mobile plate to the support structure is located on said center. Rear view mirrors generally comprise an adjustment mechanism formed by operating and mov...
