摘要： A seat back assembly for connecting a seat back shell to the seat back tubes of a wheelchair comprises a shell, upper and lower shell connectors, and upper and lower side plate portions. The lower shell connector is mounted to a lower portion of the shell. The upper shell connector is mounted to an upper portion of the shell. The upper side plate portion is adapted to be mounted to an upper portion of the seat back tube. The lower side plate portion is adapted to be mounted to a lower portion of the seat back tube at a position substantially co-linear to the posterior superior illiac spine (PSIS) of a user. The lower shell connector and the lower side plate portion are pivotally engageable with one another along a pivot axis. The upper shell connector and the upper side plate portion are attachable relative to one another at discrete locations so as to permit the angular disposition of the shell to be adjusted.
