       DESCRIPTION 
     Field of the Invention 
       [0004]    This disclosure relates to an assembly that allows the driver of a vehicle to obtain the view of incoming traffic where the incoming traffic would be headed toward the passenger&#39;s side or driver&#39;s side of the vehicle when the vehicle operated in reverse, with the use of a rear backup sideview mirror assembly.

       SUMMARY OF THE INVENTION 
       [0017]    The present disclosure is a rear backup sideview mirror assembly to enable the driver of the vehicle to see the lateral views from the back of a vehicle to aid in the prevention of accidents when operating the vehicle in reverse. 
         [0018]    The rear backup sideview mirror assembly has three embodiments. The first embodiment is a rearview mirror assembly to be used in conjunction with the rearview mirror of the vehicle. The second embodiment is driver&#39;s sideview mirror assembly to be used in conjunction with the driver&#39;s side view mirror of the vehicle. The third embodiment is passenger&#39;s sideview mirror assembly to be used in conjunction with the passenger&#39;s side view mirror of the vehicle. 
         [0019]    In each of the embodiments, to optimize the perspective view of the driver, convex mirrors are used. Regarding the use of convex mirrors, according to the optical principal Snell&#39;s Law, as regards to viewing an image in a mirror generally, the angle of incidence is equal to the angle of refraction. When a flat mirror is used to observe a reflection, the angle between the surface of the mirror and incoming view from the driver or the angle of reflection, is the same as the angle between the surface of the mirror and view from the image being viewed, or the angle of incidence and that angle is the same across the entire surface of the mirror. With the use of a convex mirror, the same optical principal applies but because of the curvature of the mirror surface, a different angle of reflection and angle of incidence across the surface of the mirror, which results in a wider perspective of view and makes the image being viewed appear closer to the mirror than the actual distance to the source of the image. The use of convex mirrors with the rear backup sideview mirror assembly means that objects can be detected that would otherwise not be detectable in a flat mirror because of the wider perspective and the enlarged image improves the visibility of those objects. 
         [0020]    The first embodiment of the rear backup sideview mirror assembly is a rearview mirror assembly wherein the driver of the vehicle can look into the rearview mirror of the vehicle to obtain a view of the rearview mirror assembly which is located on the rear of the vehicle and obtain from the rearview mirror assembly perspectives of oncoming traffic toward the driver&#39;s side of the vehicle, toward the passenger&#39;s side of the vehicle, and a downward perspective to see if anything is behind the vehicle but out of the driver&#39;s view. 
         [0021]    The second embodiment of the rear backup sideview mirror assembly is a driver&#39;s sideview mirror assembly wherein the driver of the vehicle can look into the driver&#39;s sideview mirror of the vehicle and obtain a view of from the driver&#39;s sideview mirror assembly which is located on the driver&#39;s side rear of the vehicle perspectives of oncoming traffic toward the driver&#39;s side of the vehicle or toward the passenger&#39;s side of the vehicle. 
         [0022]    The third embodiment of the rear backup sideview mirror assembly is a passenger&#39;s sideview mirror assembly wherein the driver of the vehicle can look into the passenger&#39;s&#39;s sideview mirror of the vehicle and obtain a view of from the passenger&#39;s sideview mirror assembly which is located on the passenger&#39;s side rear of the vehicle perspectives of oncoming traffic toward the driver&#39;s side of the vehicle or toward the passenger&#39;s side of the vehicle. 
         [0023]    The base of the any of the three revealed embodiments of the assembly is attached to the vehicle by a plurality of attachment means, which could include a plurality of threaded fasters, a plurality of suction cups, a plurality of magnets or a plurality of straps. Any of the plurality of convex mirrors on each of the assemblies may be adjustable to optimize the view of oncoming traffic once the rear backup sideview mirror assembly is attached to the vehicle.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0041]    A rear backup sideview mirror assembly  1  to enable the driver  2  of a vehicle  3  to see the lateral views from the back of the vehicle  3  to aid in the prevention of accidents when operating the vehicle  3  in reverse wherein there are three embodiments, a rearview mirror assembly  4 , a driver&#39;s sideview mirror assembly  5  and a passenger&#39;s sideview mirror assembly  6 . 
         [0042]    In each of the three embodiments, to optimize the perspective view of the driver, a plurality of convex mirrors  9  are used. Regarding the use of convex mirrors  9 , according to the optical principal Snell&#39;s Law, as regards to viewing an image  30  in a mirror generally, the angle of incidence is equal to the angle of refraction. When a flat mirror  25  is used to observe a reflection, the angle between the surface  29  of the flat mirror  25  and incoming view, or the angle of reflection  26 , is the same as the angle between the surface  29  of the flat mirror  25  and view from the image  30  being viewed, or the angle of incidence  27  and that angle is the same across the entire surface  29  of the flat mirror  25 . With the use of a convex mirror  9 , the same optical principal applies but because of the curvature  28  of the convex mirror  9  surface  29 , a different angle of reflection  26  and angle of incidence  27  across the surface  29  of the convex mirror  9 , which results in a wider perspective of view and makes the image  30  being viewed appear closer to the mirror than the actual distance to the source of the image  30 . The use of a plurality of convex mirrors  9  with the rear backup sideview mirror assembly  1  means that objects can be detected that would otherwise not be detectable in a flat mirror  25  because of the wider perspective and the enlarged image  30  improves the visibility of those objects in the image  30 .
