A seat assembly for an automotive vehicle comprises a seat cushion unit, a back rest unit and an arcuate guide and pivotable roller hinge arm arrangement which is rollably received in the arcuate guide and which is operable to initially guide the back rest unit upwardly and forwardly from its normal upright position to an intermediate position above the seat cushion unit when the back rest unit is moved forwardly and then allow the back rest unit to be pivoted forwardly to a folded position in which it overlies the seat cushion unit while remaining operatively connected with the arcuate guide whereby the back rest unit will have its back side substantially horizontally disposed when folded.
