ABSTRACT:
An access system for passenger boarding of a vehicle is provided. The access system includes a frame mounted to the vehicle. A ramp is movably mounted in the frame. The ramp is movable with respect to the frame between a stowed position and a deployed position with respect to the vehicle. The ramp includes side barriers extending therealong between an inboard end and an outboard end of the ramp. The side barriers are movable between a stowed orientation and a raised safety barrier orientation by an actuator. The vehicular access system includes a frame positioned below the floor level of a vehicle to which a carriage is moveably mounted. The ramp or transfer member is attached to the carriage by a pivoting rocker assembly. A drive assembly deploys and stows the ramp from the frame. An actuator is moveable between a raised safety barrier orientation and a stowed low-profile orientation with a side barrier that is pivotably mounted and spring biased toward the stowed low-profile orientation. The rocker assembly and actuator are operable with the drive assembly to raise the inboard end of the ramp to the floor level of the vehicle and to pivot the side barrier to the raised safety barrier orientation as the ramp is deployed.
