ABSTRACT:
A collapsible carriage or wheelchair, generally comprising a main frame, a seating assembly, a pair of wheel subassemblies, and a pair of rail assemblies. Preferably, the wheelchair further includes a back support assembly, an upper frame section, a front wheel, a front support assembly, and a harness system. The elements and components of the wheelchair are connected together so that the wheelchair can be quickly and easily expanded from a collapsed form to an open form. Generally, the seating assembly is provided to form a seat for a person, the wheel subassemblies are used to support the wheelchair for movement over floors and other flat surfaces, and the rail assemblies are provided to support the wheelchair for movement down stairs. The back support assembly helps to hold the wheelchair stationary while a person is being seated in the chair, the upper frame section provides direct support for the head and upper back of a person seated in the chair, and the harness system is used to hold a person in the wheelchair.
