A storage apparatus (10) attachable to a wheelchair (44) is pivotable and slidable from a storage position against the back of a wheelchair backrest to an access position adjacent to a wheelchair armrest. Pivoting and sliding is accomplished under power of an operator with the storage apparatus and slide mechanism (11) rotating substantially 90 degrees around vertical pivot member (30) and then sliding on a block member (18). A handle (24) is used to aide with the movement of the storage apparatus and to operate a locking mechanism (28), which secures the storage apparatus in access and storage positions.
