A lightweight, compact flight attendant's folding seat assembly is mounted by a plurality of separate brackets to a wall in an aircraft cabin such that the well serves as a connective support structure for various subcomponents of the seat assembly. When the seat pan is pulled down into an open position against a seat return spring, cams actuated by a seat pan frame push forward on a swingably mounted seat back frame forcing the seat back into a downwardly and forwardly sloping seating orientation. The seat back frame and cooperating cams are constructed and arranged in such a way that any rearward force exerted by the occupant against the seat back frame is reacted through the cams into the supporting wall, via the mounting brackets, wherein the intervening cams transmit the load in compression and without being subjected to rotative moment so that the seat pan is not forced to close on the seated occupant. Raising the seat pan withdraws the cams and allows the seat back to swing to a vertical position for stowage along with the upwardly folded seat pan. For maximum compactness when so stowed, the seat pan frame is provided with a contoured seat cushion that complements contouring of a seat back cushion. Integrated with the seat assembly is a retractable, occupant restraint harness including a nonbinding strap guide bracket that is attached to the same wall that mounts the seat assembly and provides for smooth, retraction and pull-out of retractable shoulder straps.
