ABSTRACT:
A wheelchair lift device including a platform located in the stepwell of a motorcoach for raising and lowering a wheelchair between a first position wherein the platform is in horizontal alignment with an elevated floor formed with the motorcoach and a second position wherein the platform is at ground level. The device includes foldable hinged sections that are positioned through a linkage to form steps for use by able-bodied persons and are extendible relative to the stepwell so as to align the hinged sections along a horizontal plane and thereby form the platform for supporting the wheelchair. In addition, a ramp is carried by one of the sections for movement from a stored position to an aligned position with the hinged sections for facilitating movement to and from the platform and to a restraining position for preventing the wheelchair from rolling off the platform.
