Abstract
An apparatus for loading a scooter-type wheelchair or similar object into a vehicle compartment such that the apparatus and wheelchair loaded thereon are fully contained within the vehicle when in a storage position. The apparatus includes a frame attachable to a lower surface of the vehicle compartment and a platform upon which the wheelchair may be rolled. A pair of upper links and a pair of lower links interconnect the frame and platform. A drive shaft interconnects the lower links, and the shaft may be rotated by an electric motor. Each upper link has a drive shaft which is connected to the first link drive shaft by a chain and sprocket assembly. Thus, as the motor rotates the lower link drive shaft, all links are rotated which raises the platform and wheelchair upwardly, traversing toward the vehicle compartment and lowering the platform and wheelchair into the compartment for storage. During this cycle, the platform passes through a vertical plane defining a maximum elevation. The platform includes wheel locators and positioning plates for locating the wheels of the wheelchair as it is positioned on the platform and for preventing the wheelchair from undesired movement once loaded.
