ABSTRACT:
An adjustable lumbar back support system mountable across the back rest of a foldable wheelchair. The system is adjustable vertically and includes two cam members eccentrically mounted on an elongated member to selectively provide fore and aft adjustment as well as side to side adjustment. Additionally, pads can be mounted on the cam members to provide a further range of support to the system. The system provides rigidity to foldable wheelchairs and pivots out of the way when the wheelchair is collapsed. The system is also lightweight and unobtrusive and may be retrofitted to most existing styles of wheelchairs.
