Abstract
A stairway for a motor coach is located in one side wall of the motor coach immediately adjacent the front wall and in front of the front wheel well. The stairway cooperates with a hinged door mounted at the front wall and openable to an angle less than 90.degree. from the coach side. The stairway is defined by a plurality of steps of equal riser height together with two vertical side walls each on a respective side of the stairway. The walls are smoothly curved around a center of curvature rearwardly of the stairway and to one side of the coach so that the stairway smoothly curves from a front edge at the doorway to a ramp section of the aisle commencing at a line at right angles to the side of the coach. The front edge of each step is at an angle to the front edge of the next step so that the steps provide gradual turning from the side of the coach to the front of the aisle. The stairway commences initially into the coach in a direction slightly toward the front of the coach so as to cooperate with the door in directing the passengers along the side of the coach, into the stairway, around the stairway and onto the aisle.
