    Abstract: A wheelchair lift, as for use with a vehicle, includes a platform for receiving a wheelchair carried as a pivot mechanism including two pairs of cooperating parallelogram structures adopted to be affixed to a vehicle for moving the platform between loading, entry and stowed positions by hydraulic actuation. A bridge plate structure is actuated by the pivot mechanism to be positioned as a bridge into the vehicle in the entry position, as a roll stop when a wheelchair is being carried and as a latch unit in the stowed position. A cam-cable mechanism actuates the bridge plate and the parallelogram structures of each pair are interlocked in moving between the stowed and entry positions.
