A foldable armrest unit for a seat having a collapsible seat back, including an armrest one end of which is articulated to first joint device affixed to a lateral surface of the seat back, the armrest unit further including an armrest support member, one end of which is articulated to the armrest and the other end of which is articulated to second joint device affixed to a lateral surface of the seat; the armrest having three limit positions: a first limit position being the position of use, in which the seat back is in an upright position and the armrest is in a substantially horizontal position; a second limit position in which the seat back is still in the upright position, while the armrest is swung towards the seat back to facilitate access to and egress from the seat, and a third limit position in which the armrest is completely folded down, together with the collapsed seat back. second portion of the rotary recliner as aforesaid by means of an idler plate, with the idler plate being in fixed relation to said second portion for selective simultaneous pivotal movement of the sector plate, the idler plate and the second portion about said lower pivot axis under control of the recliner actuation handle in said first modality; andhaving a bearing surface to which the sector plate is journalled to provide for pivotal movement of said sector plate relative to said idler plate about the lower pivot axis between a first position and a second position, thereby to define a second modality of pivotal movement of the sector plate about said lower pivot axis and to provide, when said improved vehicle seat hinge mechanism is installed in said vehicle seat assembly and through agency of said sector plate moving in said second modality, for said seat back to be pivotally movable with respect to said seat cushion about said lower pivot axis between a primary position, whereat the sector plate is at its first position, anda secondary position, tilted forwardly relative to the primary position, whereat the sector plate is at its second position; a quick-release actuation member; a first lock means for selectively releasably locking the sector plate at its first position relative to the idler plate to prevent movement of the sector plate in said second modality, such release being under control of said quick-release actuation member; and first bias means for causing said locking of the first lock means, thereby, when the improved vehicle seat hinge mechanism is installed in said vehicle seat assembly, to permit, under control of the recliner actuation handle, pivotal movement of the seat back to said preferred seating position within said range of angular positions, by agency of said sector plate moving in said first modality; to permit, under control of the quick-release actuation member, the seat back to be tilted forwardly from said preferred seating position towards a forwardly dumped position, whereat the seat back overhangs the seat cushion, by agency of said sector plate moving in said second modality; and to provide seat back memory by means of activation of said first lock means upon return of the seat back in said second modality to said preferred seating position. 2. A hinge mechanism according to claim 1, wherein the sector plate defines an upper pivot axis and the seat back mounting plate defines a seat back axis and is mounted on said sector plate for pivotal movement, about said upper pivot axis and relative to the sector plate, between an extending position, whereat the seat back axis is arranged substantially radially relative to the lower pivot axis, and a nesting position, substantially transverse to the extending position, so as to provide, when said hinge mechanism is installed in said vehicle seat assembly, for said seat back to be pivotally movable with respect to said seat cushion, by agency of said seat back mounting plate pivotally moving between its extending position and its nesting position, between a substantially upright position within the range and a fold-flat position, whereat the seat back substantially horizontally overlies the seat cushion.3. A hinge mechanism according to claim 2, further comprising a second lock means for selectively releasably locking the seat back mounting plate at its extending position.4. A hinge mechanism according to claim 3, further comprising second bias means for causing said locking of the second lock means.5. A hinge mechanism according to claim 4, further comprising an actuation means for releasing the second lock means, under control of the recliner actuation member, upon pivotal movement of the seat back to the upright position from a triggering position which is tilted rearwardly relative to the upright position.6. A hinge mechanism according to claim 5, wherein the first lock means comprises: a first latching lug portion formed on the i
