ABSTRACT:
An accessory-supporting attachment frame is removably coupled to the vertical bracing members which extend downwardly from the front terminus portions of the wheelchair armrests, said bracing members being disposed substantially rearwardly of the front edge of the wheelchair seat. The coupling is of the swing-down type. Stabilizing locators extend downwardly from the frame and engage the bracing members to position the frame horizontally. The frame is disposed below the plane of the armrests and extends from between the chair back and front seat edge and forwardly to beyond said edge. The frame is adapted to receive thereover an accessory, such as a tray, via a connection therebetween which permits support of the accessory on the tray while holding the accessory against horizontal movement. The coupling between the frame and bracing members is such as to be automatically releasable to protect the patient in the event the wheelchair tips forwardly so that the front edge of the frame and/or accessory engages the floor.
