ABSTRACT:
A school bus is equipped with a crossing arm mechanism that is mounted on the front bumper at the passenger side. The mechanism includes a crossing arm assembly that is pivoted between a retracted (stored) position adjacent the front bumper and an extended (operative) position where the crossing arm assembly extends outwardly of the bus bumper in a perpendicular fashion to control pedestrian traffic. The crossing arm assembly includes a plastic bracket that is pivotally attached to an actuating mechanism and a cantilever beam that is attached to the bracket at one end. The bracket has two vertically spaced pivot arms and a beam mounting portion that supports the cantilever beam. The cantilever beam is a plastic extrusion that comprises upper and lower tubular sections that are interconnected by a web portion. The extrusion is modified at one end for attachment to the bracket.
