Vehicle adjustable and stowable rear seat

Abstract

A longitudinally adjustable vehicle seat, including a seat cushion and a seatback, is supported on a bi-level seat frame for movement from an occupant in-use position to a compact fold-flat stowed position. The bi-level seat frame includes a front lower portion slidably supported on front track assemblies and a rear elevated portion slidably supported on rear track assemblies. A pair of forward upright links each has a lower end pivoted on the seat frame front portion for rotation about a first transverse axis and upper ends pivoted to associated front underlying portions of the seat cushion for rotation about a second transverse axis. A pair of upstanding laterally spaced arms each has a lower end fixed to an aft end of the seat cushion and an upper end pivoted to an intermediate portion of the seatback for rotation about a third transverse axis. The seatback has its lower portion pivoted to a pair of pivot mounts on the seat frame elevated portion for rotation about a fourth transverse pivot axis. Upon the seatback being unlatched and pivoted forwardly about the pivot mounts, the seat cushion undergoes conjoint parallelogram movement, about the four pivot axes to a stowed position adjacent the floor of the vehicle, wherein the seatback is stowed in an overlying manner relative to the seat cushion. The rear surface of the stowed seatback is disposed flush with the surface of the vehicle elevated rear cargo load floor.
