A seat assembly for supporting an occupant above a floor of an automotive vehicle includes a seat cushion extending laterally between spaced apart side members. The seat cushion includes a front cross member extending between the side members. Inboard and outboard front legs are each pivotally assembled at one end to the front cross member for pivotal movement of the seat cushion relative to the front legs between a seating position and forwardly dumped positions. A boss protrudes outwardly from the front cross member for pivotal movement therewith relative to the front legs. A guide flange is fixedly secured to one of the front legs and has a cam surface cammingly engagable with the boss for automatically laterally displacing the seat cushion in response to pivotal movement of the seat cushion relative to the front legs between the seating and forwardly dumped positions.
