Seat back recliner kit for wheelchair

A seat back recliner kit for attachment to a wheelchair which does not have a reclining seat back. A separate recliner mechanism is attached to each side frame for the wheelchair. Each recliner mechanism includes a rear wheel mounting bracket which attaches to the side frame for providing one or more rear wheel mounting locations spaced further to the rear of the wheelchair than the original rear wheel mounting locations. The new rear wheel mounting locations provide stability when the wheelchair is occupied with the seat back reclined. A pivoting seat back support is attached to the rear of each wheelchair side frame and the wheelchair seat back is attached to the pivoting seat back supports. An adjustable length brace extends between each seat back support and a rear wheel mounting block for adjusting the seat back angle. The brace is released by operating a hand lever while the seat back angle is adjusted and is locked when the lever is released.
