A low-floor-vehicle ramp has a slideway (13) attached to a bottom side of a vehicle floor (2) proximate a door sill, a boarding-ramp assembly (1) hinged to a ramp-control plate (14) that slides on parallel slideways (22, 23, 59, 60, 68) as actuated horizontally by motorized bidirectional actuation o

A low-floor-vehicle ramp has a slideway (13) attached to a bottom side of a vehicle floor (2) proximate a door sill, a boarding-ramp assembly (1) hinged to a ramp-control plate (14) that slides on parallel slideways (22, 23, 59, 60, 68) as actuated horizontally by motorized bidirectional actuation of a ramp-slide actuator (16, 56) that is affixed to the vehicle (3) and has a horizontally actuating member (17, 58) attached to the ramp-control plate. A floor-access plate (9) forms an access bridge between the boarding-ramp assembly and the vehicle floor. Foldable side barriers (7, 8) on outside edges of the boarding-ramp assembly spring to an upright mode automatically in extended mode. A ramp switch (10) is operated by a driver of the vehicle. Tool-operative backup gearing (19) is provided for operation with various types of hand-operative or motor-operative tools (20, 21) in event of failure of the ramp-slide actuator.

A low-floor-vehicle ramp comprising: a slideway attached to a vehicle proximate a bottom side of a floor of the vehicle at a position vertically below a door sill of the vehicle; a boarding-ramp assembly positioned selectively intermediate a vehicle-travel mode on the slideway and a handicap-pickup mode extended from the slideway; a ramp slide having sliding attachment to the slideway; a ramp-control plate on the ramp slide; a ramp floor on the boarding-ramp assembly; the boarding-ramp assembly having an inside end that is hinged to an outside edge of the ramp-control plate; a ramp-slide actuator affixed to the vehicle and having a horizontally actuating member attached to the ramp-control plate; a ramp-support member attached to the vehicle and having a ramp-support surface positioned proximate an outside edge of the vehicle and designedly lower vertically than the door sill; a floor-access plate having an inside edge hinged to an outside edge the floor at a position proximate the door sill; the floor-access plate having an outside edge resting on the ramp-support member with the boarding-ramp assembly in a vehicle-travel mode and the outside edge of the floor-access plate being positioned proximate a top surface of the ramp floor with the boarding-ramp assembly in handicap-pickup mode; and side barriers on sides of the boarding-ramp assembly.
