Rear-view device for motor vehicles
The invention relates to a rear-view device for motor-vehicles which operates like a rear-view mirror, which may be inserted into the classical mirror mounting. According to the invention, the device consists of a diopter made of glass or a transparent plastic material and which may have a, spherical-, conical- or profiled shaped, prism with more convex and concave surfaces having on one side a fixed or mobile mirror, mounted so that some incidental rays suffer refractions at the level of the surfaces of the diopter, and the reflection on the mirror, in their way towards an observer, avoiding the limit angle of total reflection, in the visibility area. The mobile mirror may have variable convergence.
