A wheelchair having opposing sideframes each of which comprise a base section which is pivotally connected by a brace member to an inclinable seat section. An extender mechanism interconnects the seat section to a brace member and provides releasable securement for a wheelchair seat at selected angular positions. Backrest bars are independently adjustable with a similar extender mechanism that interconnects the bars with a respective seat section. The sideframes are spaced-apart with hinged spacer bars which includes a latching device for releasably securing the bars in an open position. The bar and frame sections have elongated slots containing fasteners for adjustable connections with fasteners from adjunct wheelchair assemblies.
