| 摘要 |
A mechanical device integrating the conventional, internal rear view mirror (2), directly adaptable on conventional rear view mirrors (2) or encompassed in those newly manufactured, made, essentially, of a body (1) on which are two preoriented mirrors (5,6), both capable of independent adjustment. This device, that has the same transversal size of the conventional rear view mirrors (2), extends the posterior visual angle in all directions. This invention is particularly suitable to increase the safety of manoeuvres, that need as wide as possible rear visual angle.
