  • Bumper integrated school bus safety arm
    Patent number: 6213526
    Abstract: A school bus crossing or a mounting system that more fully integrates the crossing arm and the bumper. To achieve this, the primary mounting brackets for the crossing arm drive system may be mounted to the bus chassis and an opening is formed in the bumper itself. The crossing arm is mounted to the drive system such that the arm projects through the opening in the bumper. Alternatively, the primary mounting brackets may be mounted to an inner surface of the bumper. A recess may be formed into an outer surface of the bumper such that the crossing arm is at least partially tucked into the recess when retracted. In one embodiment, there is no recess in the bumper. The crossing arm is contoured to follow the outer surface of the bumper.
