Abstract
A school bus has a stop sign hinged on a sealed electrical actuator assembly that is attached to the side of the bus. The actuator assembly includes the electrical and mechanical components including an electric motor that pivot the hinged stop sign from a stored position adjacent the bus to an operative position extending outwardly of the bus in perpendicular fashion and back to the stored position. These components and wiring harnesses are protected in an outer sealed housing that has a removable cover to facilitate installation and repair. Installation and repair is further enhanced by a removable inner housing sub-assembly that carries a motor control circuit for the electric motor and provides additional protection for the electric motor. The school bus also has a crossing arm hinged on an identical sealed electrical actuator assembly, that is attached to the front bumper of the bus near the passenger door.
