Abstract
A wheelchair back assembly suitable for detachable mounting to the back-supporting posts of a wheelchair. The back assembly includes a relatively rigid shell member carrying post-engaging hooks and a plurality of mounting units formed to be mounted on the wheelchair posts. The mounting units are further formed to slidably receive and automatically releasably lock a pair of the post-engaging hooks on the shell member to the posts against unintentional removal of the back assembly from the wheelchair during normal use of the wheelchair. The mounting units are also formed for single-handed automatic unlocking and release of the pair of hooks from the mounting units and posts upon rotation of the shell member forwardly over the wheelchair seat by an amount in excess of any displacement occurring during normal use of the wheelchair.
