A wheelchair has lateral frames each constituted by a prefabricated modular front frame unit and a prefabricated modular rear frame unit secured together against relative longitudinal movement. The front frame unit has a post from which upper and lower rail sections extend in engagement with rail sections secured to a rear post which acts as a wheel mounting tube. The rail sections are interlinked by a spacer tube which carries a pivot sleeve of a cross-brace member. The upper rail section carries a mounting socket for a prefabricated backrest tube. The frame components may be prefinished for local assembly and permit a wide range of wheelchairs of different length, width and backrest configurations to be manufactured from a restricted range of standard parts.

A wheelchair frame adapted to be associated with supporting wheels, the frame being assembled from a plurality of modular units of prefabricated standard configuration that are adapted to be variably positioned relative to one another at the time of assembly and then fixed in adjusted position relative to one another to provide a wheelchair frame having dimensions corresponding to the specific requirements of an individual user of the wheelchair, said wheelchair frame including a pair of opposed parallel lateral frame structures adapted to be disposed in horizontally spaced relation to one another, each of said lateral frame structures comprising: a prefabricated modular forward frame unit having integral upper and lower rail sections; a prefabricated modular rear frame unit having integral upper and lower rail sections, the rail sections of the prefabricated modular forward and rear frame units being respectively disposed in opposing aligned relation to one another to define at least part of upper and lower rails of a closed frame structure, said upper and lower rails being arranged to telescope by displacement of said forward and rear frame units relative to one another in a direction parallel to the directions of said upper and lower rail sections thereby to permit adjustment of the length of said rails to a desired value within a range of lengths during assembly of said wheelchair frame, and means for permanently securing said forward and rear frame units to one another against relative longitudinal movement as assembled at the desired rail length of said closed frame structure.
