Abstract
A wheelchair back assembly is provided which has a back plate held in position relative to upright wheelchair cane members by opposed independent mounting assemblies. The mounting assemblies include a support bar which carries a bracket attached to the back support plate. The assemblies further include universal cane clamp members hingedly attached to a pivot mechanism that allows for independent bi-lateral adjustment in a direction transverse to the longitudinal axis of the seat of the wheelchair. The clamping member further includes a through bore, which is seated on the spindle of a compression latch secured to the upright canes of a wheelchair. A pivotable lever acts as a latch member as it compresses elastomeric O-rings in order to latch the hinge in position relative to the spindle member and to provide for a resilient attachment. The lever also has a locking position to retain the lever in its latched position. The plate is further provided with lateral stabilizer members, which are adjustable in and out. It is provided as well as with a cushion and modesty shroud.
