ABSTRACT:
A dual visor operating mechanism in which respective locks disposed between inner and outer visor arm hubs and respective right and left arbors normally prevent movement of the visors in response to force applied directly thereto and in which respective inner and outer visor actuators sequentially release their associated brakes and then move the visors therewith. Brakes prevent movement of the visors after release of the associated lock and before the corresponding visor moves with the actuator.
