  • Patent number: 4155468
    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.
