  • the present invention relates in general to a rearview mirror system for vehicles and, more particularly, to a structural improvement in such a rearview mirror system for giving a wider rear view to drivers-
  • vehicles are typically provided with a plurality of accessaries for making driving more convenient and safer for the driver.
  • a vehicle is typically equipped with various types of reflection mirrors for allowing the driver to view the traffic conditions behind the vehicle while driving.
  • the above reflection mirrors equipped in the vehicle include a rearview mirror mounted to the upper front center inside the vehicle's cabin.

  • the typical rearview mirror sometimes fails to allow the driver to drive the vehicle safely. That is, the above typical rearview mirror only gives a limited rear view to the driver as traffic conditions behind the vehicle are partially intercepted by the car body when they are reflected by the rearview mirror. That is, both the rear windshield support frame and trunk of the car body partially intercept the light originating from the traffic conditions behind the vehicle.
  • the field of the rear view provided by the above rearview mirror is limited to the upper and lower angles of about 10 * and left and right angles of about 30 * .

  • the typical rearview mirror mounted to the front center inside the cabin fails to prevent dead angle traffic accidents while driving. That is, the above rearview mirror cannot allow the driver to see the dead spaces about the rear side corners and just below the back of the car body. The above rearview mirror thus often fails to prevent the dead angle traffic accidents while passing, backing up or changing lanes.

Abstract

Système amélioré de rétroviseur destiné à des véhicules. Dans ce système, une lentille orientable (V) est montée à l'arrière du véhicule et un réflecteur parabolique ou ellipsoïdal (M) est monté à l'avant du véhicule. Ce réflecteur comporte un paraboloïde de révolution ou un ellipsoïde de révolution, selon le cas. Le système de rétroviseur reflète ce qui se passe derrière le véhicule sans aucune distorsion d'image, ce qui donne au conducteur une bonne visibilité arrière. Il lui donne un champ de vision aussi large que s'il observait directement ce qui se passe derrière le véhicule à travers la lunette arrière. Ce champ de vision n'est pas altéré par la présence de passagers sur le siège arrière, ce qui donne davantage de sécurité au conducteur lors de la conduite du véhicule.
