Definitions

  • the present invention relates to a rearvie mirror for a vehicle and more particularly to a rearview mirror combining a flat and a convexly curved reflective surface to provide, in combination, an enhanced field of rearward vision.
  • a rearview mirror for a vehicle comprising a first planar reflective surface, a second longitudinally convex reflective surface providing a wider field of rearward vision relative to the first reflective surface, a frame surrounding the first and second reflective surfaces for maintaining the second reflective surface in a fixed position in parallel longitudinal alignment with the first reflective surface, and markings adjacent the second reflective surface providing a visual indication of a safe lane changing zone.
  • Figure 1 is a front elevational view of the present mirror
  • Figure 2 is a rear elevational view of the mirror of Figure 1;
  • Figure- 3 is a top plan view of the mirror of Figure 1;
  • Figure 4 is a bottom plan view of the mirror of Figure 1;
  • Figure 5 is a side elevational view of an end of the mirror of Figure 1.
  • present mirror 1 combines a conventional first flat reflective surface 4 and a second longitudinally convex reflective surface 8.
  • Mirror 4 provides the usual undistorted but limited field of rearward vision whereas mirror 8, being convex, provides a much wider rearward field of vision which overlaps to both sides with most persons natural peripheral vision, thereby all but eliminating the blind spots in the field of view afforded by mirror 4 alone.
  • both of mirrors 4 and 8 Surrounding both of mirrors 4 and 8 is a frame 12 including a backing 13 and relatively thin raised edges 15 which overlap the adjacent edges of mirrors 4 and 8 to retain the mirrors firmly in place in fixed positions relative to each other. As shown, both mirrors as retained by frame 12 are in parallel longitudinal alignment with mirror 8 preferably, but not necessarily, located vertically above mirror 4.
  • Frame 12 is formed integrally about both mirrors to provide a unitary, seamless, aesthetically pleasing appearance while at the same time making the mirror as a whole compact, unobtrusive, easy to adjust and rigid.
  • the vertical height of mirror 8 is less than that of mirror 4.
  • convex mirrors tend to distort distances, making objects appear further away than they really are. It is important therefore that some means be provided to provide a visual indication of which vehicles appearing in the mirror's field of vision are sufficiently distant to permit a safe lane change.
  • Scale 20 is sub-divided into visually distinct zones 21, 22 and 23 distinguished from one another such as by means of colour, texture or some other form of marking.
  • zones 21 and 23 are coloured red, whereas zone 22 is white, both of which colours contrast with the typically dark plastic or resinous material of frame 12.
  • Any vehicle appearing in mirror 8 beneath zones 21 and 23 is too close to permit a safe lane change.
  • Any vehicle appearing in mirror* 8 beneath white zone 22 is usually sufficiently distant to permit a safe lane change, subject to the usual considerations such as road conditions, weather, the other vehicle's speed of approach and of course the level of traffic.
  • Scale 20 may be marked on mirror surface 8 itself, or the mirror may be sub-divided by means of thin vertical lines 29 (shown in dotted lines) separating the safe and not-safe lane changing zones in the field of vision. Another alternative is to tint the not-safe zones a different colour relative to the safe zone.
  • mirror 1 is conventional in construction and includes the usual post 30 with a ball joint 31 at one end to provide full adjustability of the mirror's angle relative to the driver's eyes and a foot 32 at the other end for attachment to the car's windshield.
  • the mirror may also include a da /night switch 40.

Abstract

On décrit un rétroviseur amélioré pour un véhicule, comprenant une première surface plane réfléchissante (4), une seconde surface réfléchissante (8) convexe dans le sens longitudinal offrant un champ de vision arrière élargie par rapport à la première surface réfléchissante, un cadre (12) entourant les première et seconde surfaces réfléchissantes afin de les maintenir en une position fixe et en alignement longitudinal et parallèle l'une par rapport à 'autre, et des repères (20) adjacents à la seconde surface réfléchissante pour fournir une indication visuelle d'une zone de changement de voie sûre.
