A seat assembly has a seat cushion that is pivotally mountable to a vehicle floor. The seat cushion is selectively movable between an operative condition and a standup condition. A seat back is pivotally mounted to the seat cushion and is selectively movably angularly relative to the seat cushion. A pair of hinges pivotally receives the seat back and is linked to the seat cushion, whereby movement of the seat cushion from the operative condition to the standup condition rotates the pair of hinges, generally aligning the seat cushion and the seat back when the seat cushion is tumbled forward.
