Maximum length, shortest height
As the name suggests this platform type folds horizontally when stowed. Effectively making a long platform, short when stowed and thereby making it possible to install in a vehicle with a low roof. This is useful for longer mobility devices that need the extra platform space, such as scooters and power chairs. Another use of the folding design is to keep stowed platform below the rear window. This way the vehicle's driver and passengers can have an unblocked view through the window.
