ABSTRACT:
A ramp assembly for use with a vehicle to provide access to and from the vehicle. The ramp assembly is particularly suited for use by people confined to a wheel chair. The assembly includes a control lever pivotally mounted to a ramp member of the assembly to support a control switch at hand level to someone in a wheel chair. The control lever abuts a portion of the vehicle as the ramp assembly closes and is supported in a substantially vertical position when the assembly is closed to increase the space available within the vehicle. The motor drive for the ramp assembly is positioned on the vehicle between two pivotally mounted ramp members to further increase the available space within the vehicle over past assemblies. The present ramp assembly includes a number of safety features including a warning light system that is turned on when the ramp assembly is in use, automatic stops for the ramp assembly's motor, built-in steps for persons walking on the ramp assembly or pushing a wheel chair over the assembly, windows in the main ramp member for increased visibility, and means to positively move the outer ramp members to a position substantially coplanar with the main ramp member for easy movement between the ramp assembly and the ground.
