Abstract: A bus boarder for a wheelchair and its occupant and for the ambulatory impeded, embodies an elevator platform which is mounted within the entrance area at the front of the bus. The floor and the steps at the entrance are removed and a U-shaped reinforcing frame forms a well for the elevator platform. The elevator platform and its operating mechanism are so constructed that the doors open against each side of the entrance opening as originally provided for the bus. The elevator platform is lowerable to the ground or curbstone with the steps folded into a ramp for the wheelchair which is moved thereon by its occupant or an attendant and onto the platform. A fare box is mounted on a pivoted arm which is rotatable horizontally into a well in the bus dashboard, so as not to impede either the vertical motion of the elevator platform, or the maneuvering of the wheelchair thereon. The wheelchair occupant enters the platform backwards if the chair is of extended size, or if of standard size either forward or backward.
