Seat back automatic height adjuster and recliner mechanism

摘要

A passenger seat assembly (10) for a motor vehicle (12) includes a seat bottom (24) and seat back (26) which can be folded to a horizontal stowed position for increased storage capacity. The seat assembly (10) comprises a linear recliner (66) for adjustment of the seat back (26) in the upright position and to selectively facilitate forward pivotal folding of the seat back (26) to overlap and cover the seat bottom in the stowed position. The seat back (26) also includes a lower portion (150) pivotally attached to a support stanchion (28) and an upper portion (152) connected to the lower portion (150). An adjustment mechanism (154) automatically adjusts the vertical height of the seat back (26) from a retracted position with the upper portion (152) extended upwardly from the lower portion (150).
