Abstract: A rear viewing system allowing the driver to view occupants near the back of the bus comprises of a mirror resiliently mounted to a backing support member. The backing support member is attached to the back of the bus via two types of brackets. The first mounting bracket includes a mounting flange secured to the backing support member and an adjustable length L-shaped strut pivotally connected to the mounting flange and having a mounting surface adapted to be mounted flush to an interior wall of the bus. The second type of mounting bracket has two major components, a backing member strut and a securing strut. The backing member strut is essentially L-shaped as is the securing strut. The second mounting bracket is adjustable in that a fastener connects aligned openings in the backing member strut and securing strut.
