AI Technical Summary

Benefits of technology

This approach reduces the natural frequency of the passenger-side mirror system below 60 Hz, enabling the use of lighter materials without distorting the image, thus lowering vehicle weight, reducing costs, and improving fuel efficiency.

Problems solved by technology

However, the use of heavier material results in undesirable characteristics such as a heavier overall vehicle weight, increased mirror cost, and higher fuel consumption.

Embodiment Construction

[0015]Referring now to FIGS. 1 and 2, a motor vehicle 16 is shown from the rear having a passenger-side rearview mirror system 10 and a driver-side rearview mirror system 10′ each of which is mounted to the vehicle 16 in a conventional manner. The passenger-side mirror system 10 comprises a convex reflective element assembly 12 providing an image 18 of an object located rearward of the vehicle. The driver side mirror system 10′ comprises a planar reflective element assembly 12′ providing an image 18′ of the same object. The magnification provided by the driver side mirror system 10′ is 1:1. The magnification provided by the passenger-side mirror system 10 is approximately 2:1.

[0016]The passenger-side reflective element assembly 12 is mounted to the motor vehicle 16 through a base assembly 14. The driver-side reflective element assembly 12′ is mounted to the motor vehicle 16 through a base assembly 14′. The rearview mirror system 10, 10′ can be adapted for pivotal connection of the r...

Abstract

A rearview mirror system comprising a passenger-side mirror having a lower natural frequency and / or more resiliency than the driver-side mirror.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. provisional application Ser. No. 60 / 481,837, filed Dec. 29, 2003, which is incorporated herein in its entirety.FIELD OF THE INVENTION[0002]The invention relates to a rearview mirror system for a motor vehicle, and more particularly to a rearview mirror system comprising a lightweight mirror base exhibiting a reduced natural frequency of vibration.DESCRIPTION OF THE RELATED ART[0003]Rearview mirror systems are ubiquitous for motor vehicles, and can include both driver-side and passenger-side mirrors. The purpose of the rearview mirror system is to provide the driver with a rearward view during operation of the motor vehicle. The driver side mirror typically utilizes a flat reflective surface providing an image magnification of 1:1. In contrast, the passenger-side mirror typically utilizes a convex reflective surface to provide a wider field of view to the driver. This results in an image magnifica...
