Fold and tumble seat support assembly

A fold and tumble seat support assembly (10) for removably securing a vehicle seat to a pair of front and rear strikers (12, 14) on the floor (16) of a vehicle. The seat support assembly includes a riser (20) having a pair of forward (32) and rearward (34) legs. A rear latch (36) is pivotally connected to each of the rearward legs (34) and operable by a first linkage mechanism (40) to latch and unlatch with the rear strikers (14). A front latch (64) is pivotally connected to each of the forward legs (32) and operable by a front latch handle (68) to latch and unlatch with the front strikers. A rear support leg (74) supports the rearward legs (34) of the riser above the vehicle floor (16). A foot bracket (56) is pivotally connected to each of the forward legs (32) for supporting the riser (20) above the vehicle floor (16) between both a generally horizontal use position and a forwardly pivoted tumbled position. A second linkage mechanism (72) is connected between the foot brackets (56) and the rear support legs (74) for automatically retracting the rear support legs (74) against the riser (20) in response to pivotal movement of the seat about the foot bracket (56) from the use position to the tumbled position. A pair of front (92) and rear (96) wheels are connected to the foot brackets (56) and rearward legs (74), respectively, for providing rolling support of the seat when removed from the vehicle in a roll-away position.
