Abstract

A storage compartment for a wheelchair includes a lower tray for holding at least one item, the lower tray or a holding member for the lower tray, being bolted permanently to one arm of the wheelchair and the lower tray having an upper opening. A cover member is pivotally secured on the lower tray for covering the upper opening of the lower tray when the cover member is in a closed position, the cover member having an upper surface which provides an arm rest for a user of the wheelchair. Detachable storage compartments, and compartments for use with clothing guards, are also disclosed. The device is adaptable to all known wheelchairs, and can be used to replace existing arm rests.
