  • Patent number: 5621569
    Abstract: The invention concerns a vehicle rear-view mirror (1) comprising a plane-mirror section (2) and at least one convex section (3, 11) contiguous with the sides of the plane section. The curvature of the convex side sections is zero at the transition line (4, 12) with the plane-mirror section (2), and increases progressively with increasing are length (L) from the transition line, the cur of vertical orthogonal lines of intersection being equal to the curvature of a horizontal reference line (6, 6A) at their point of intersection. The rear-view mirror (1) proposed enables the driver to view both behind and to the side. The mirror (1) is easy to produce since the curvature of the convex side sections (3, 11) only departs by a small amount from the plane of the plane-mirror section (2).
