A frame securement belt (40) is attached to each of the four corners of the wheelchair frame so that four belts (40) secure the chair to the track sections (12,14). Independent occupant securement is provided with a lap belt (70) which attaches on each side of chair (C) to a track section (12,14). A shoulder harness (90) attaches to the floor behind the occupant of the chair and rearwardly of the occupant separates into two shoulder sections (98) which have buckle loops (102) which secure to the releasable buckle (78,80) of the lap belt (70). A rear stanchion (120) may be provided by attaching the same to the track sections and passing the rearward part of the shoulder harness over the upper part (122) of the stanchion.
