A link configuration for a wheelchair having laterally spaced side frames comprises a plurality of links extending between the wheelchair side frames. Each link has opposing ends. One of the ends of each link is pivotally coupled to one of the side frames. The other end of each link is pivotally coupled to the other side frame. Each link has a hinge to permit the links to fold. The links are foldable in non-parallel planes relative to one another. An interference member coupled to the hinge of one of the links is engageable with the hinge of the other link upon unfolding the links to couple the links together.
