Abstract
The invention relates to means for releasably connecting a wheelchair backrest to a wheelchair frame. This is desirable to facilitate collapse of the wheelchair for transport or storage. In the preferred embodiment there is a wheelchair having a support frame, a backrest () and connector comprising a saddle () and a clamp (). The saddle has a slot () with top and front openings and a locking lever (). Two pins () are received in the slot so they extend through the front opening, and the lever () is able to move to divide the slot into top and bottom zones so that a lower one of the pins is prevented from being withdrawn from the slot via the top opening by the lever. The lever can then be moved to unblock the lower pin and allow the slot () and the pins () to be dissociated.
