Abstract: A tablet arm assembly for mounting on a wheelchair or the like comprises a tablet arm, a telescoping support for mounting the tablet arm on the wheelchair, a pivot mechanism for pivotally connecting the tablet arm to the support to permit the tablet arm to pivot from a horizontal use position to a vertical storage position alongside the wheelchair, and a slide mechanism for slidably connecting the tablet arm to the support to permit the tablet arm to be adjusted in its horizontal use position and slide downward into its vertical storage position. The pivot mechanism comprises a two-way hinge adapted to permit the table arm to be flipped up from its horizontal use position and to pivot downward to its vertical storage position. The two-way hinge is adjustable to permit the tablet arm to pivot downward in either a forward or rearward direction relative to the wheelchair.
